Inhibition of in vitro enteric neuronal development by endothelin-3: mediation by endothelin B receptors. (1/16085)
The terminal colon is aganglionic in mice lacking endothelin-3 or its receptor, endothelin B. To analyze the effects of endothelin-3/endothelin B on the differentiation of enteric neurons, E11-13 mouse gut was dissociated, and positive and negative immunoselection with antibodies to p75(NTR )were used to isolate neural crest- and non-crest-derived cells. mRNA encoding endothelin B was present in both the crest-and non-crest-derived cells, but that encoding preproendothelin-3 was detected only in the non-crest-derived population. The crest- and non-crest-derived cells were exposed in vitro to endothelin-3, IRL 1620 (an endothelin B agonist), and/or BQ 788 (an endothelin B antagonist). Neurons and glia developed only in cultures of crest-derived cells, and did so even when endothelin-3 was absent and BQ 788 was present. Endothelin-3 inhibited neuronal development, an effect that was mimicked by IRL 1620 and blocked by BQ 788. Endothelin-3 failed to stimulate the incorporation of [3H]thymidine or bromodeoxyuridine. Smooth muscle development in non-crest-derived cell cultures was promoted by endothelin-3 and inhibited by BQ 788. In contrast, transcription of laminin alpha1, a smooth muscle-derived promoter of neuronal development, was inhibited by endothelin-3, but promoted by BQ 788. Neurons did not develop in explants of the terminal bowel of E12 ls/ls (endothelin-3-deficient) mice, but could be induced to do so by endothelin-3 if a source of neural precursors was present. We suggest that endothelin-3/endothelin B normally prevents the premature differentiation of crest-derived precursors migrating to and within the fetal bowel, enabling the precursor population to persist long enough to finish colonizing the bowel. (+info)A Wnt5a pathway underlies outgrowth of multiple structures in the vertebrate embryo. (2/16085)
Morphogenesis depends on the precise control of basic cellular processes such as cell proliferation and differentiation. Wnt5a may regulate these processes since it is expressed in a gradient at the caudal end of the growing embryo during gastrulation, and later in the distal-most aspect of several structures that extend from the body. A loss-of-function mutation of Wnt5a leads to an inability to extend the A-P axis due to a progressive reduction in the size of caudal structures. In the limbs, truncation of the proximal skeleton and absence of distal digits correlates with reduced proliferation of putative progenitor cells within the progress zone. However, expression of progress zone markers, and several genes implicated in distal outgrowth and patterning including Distalless, Hoxd and Fgf family members was not altered. Taken together with the outgrowth defects observed in the developing face, ears and genitals, our data indicates that Wnt5a regulates a pathway common to many structures whose development requires extension from the primary body axis. The reduced number of proliferating cells in both the progress zone and the primitive streak mesoderm suggests that one function of Wnt5a is to regulate the proliferation of progenitor cells. (+info)Retinoids are produced by glia in the lateral ganglionic eminence and regulate striatal neuron differentiation. (3/16085)
In order to identify molecular mechanisms involved in striatal development, we employed a subtraction cloning strategy to enrich for genes expressed in the lateral versus the medial ganglionic eminence. Using this approach, the homeobox gene Meis2 was found highly expressed in the lateral ganglionic eminence and developing striatum. Since Meis2 has recently been shown to be upregulated by retinoic acid in P19 EC cells (Oulad-Abdelghani, M., Chazaud, C., Bouillet, P., Sapin, V., Chambon, P. and Dolle, P. (1997) Dev. Dyn. 210, 173-183), we examined a potential role for retinoids in striatal development. Our results demonstrate that the lateral ganglionic eminence, unlike its medial counterpart or the adjacent cerebral cortex, is a localized source of retinoids. Interestingly, glia (likely radial glia) in the lateral ganglionic eminence appear to be a major source of retinoids. Thus, as lateral ganglionic eminence cells migrate along radial glial fibers into the developing striatum, retinoids from these glial cells could exert an effect on striatal neuron differentiation. Indeed, the treatment of lateral ganglionic eminence cells with retinoic acid or agonists for the retinoic acid receptors or retinoid X receptors, specifically enhances their striatal neuron characteristics. These findings, therefore, strongly support the notion that local retinoid signalling within the lateral ganglionic eminence regulates striatal neuron differentiation. (+info)Deletion analysis of the Drosophila Inscuteable protein reveals domains for cortical localization and asymmetric localization. (4/16085)
The Drosophila Inscuteable protein acts as a key regulator of asymmetric cell division during the development of the nervous system [1] [2]. In neuroblasts, Inscuteable localizes into an apical cortical crescent during late interphase and most of mitosis. During mitosis, Inscuteable is required for the correct apical-basal orientation of the mitotic spindle and for the asymmetric segregation of the proteins Numb [3] [4] [5], Prospero [5] [6] [7] and Miranda [8] [9] into the basal daughter cell. When Inscuteable is ectopically expressed in epidermal cells, which normally orient their mitotic spindle parallel to the embryo surface, these cells reorient their mitotic spindle and divide perpendicularly to the surface [1]. Like the Inscuteable protein, the inscuteable RNA is asymmetrically localized [10]. We show here that inscuteable RNA localization is not required for Inscuteable protein localization. We found that a central 364 amino acid domain - the Inscuteable asymmetry domain - was necessary and sufficient for Inscuteable localization and function. Within this domain, a separate 100 amino acid region was required for asymmetric localization along the cortex, whereas a 158 amino acid region directed localization to the cell cortex. The same 158 amino acid fragment could localize asymmetrically when coexpressed with the full-length protein, however, and could bind to Inscuteable in vitro, suggesting that this domain may be involved in the self-association of Inscuteable in vivo. (+info)JunB is essential for mammalian placentation. (5/16085)
Lack of JunB, an immediate early gene product and member of the AP-1 transcription factor family causes embryonic lethality between E8.5 and E10.0. Although mutant embryos are severely retarded in growth and development, cellular proliferation is apparently not impaired. Retardation and embryonic death are caused by the inability of JunB-deficient embryos to establish proper vascular interactions with the maternal circulation due to multiple defects in extra-embryonic tissues. The onset of the phenotypic defects correlates well with high expression of junB in wild-type extra-embryonic tissues. In trophoblasts, the lack of JunB causes a deregulation of proliferin, matrix metalloproteinase-9 (MMP-9) and urokinase plasminogen activator (uPA) gene expression, resulting in a defective neovascularization of the decidua. As a result of downregulation of the VEGF-receptor 1 (flt-1), blood vessels in the yolk sac mesoderm appeared dilated. Mutant embryos which escape these initial defects finally die from a non-vascularized placental labyrinth. Injection of junB-/- embryonic stem (ES) cells into tetraploid wild-type blastocysts resulted in a partial rescue, in which the ES cell-derived fetuses were no longer growth retarded and displayed a normal placental labyrinth. Therefore, JunB appears to be involved in multiple signaling pathways regulating genes involved in the establishment of a proper feto-maternal circulatory system. (+info)Cloning of a novel gene specifically expressed in clonal mouse chondroprogenitor-like EC cells, ATDC5. (6/16085)
We cloned a full-length cDNA encoding a novel mouse protein, A-C2, by differential display method using mouse embryonic fibroblast C3H10T1/2 cells and mouse chondroprogenitor-like EC cells, ATDC5. The deduced amino acid sequence of A-C2 consisted of 106 amino acids with no significant homology to the sequences previously reported. Northern blot analysis showed two major bands of 2.1 and 1.8 kb sizes. Expression of A-C2 mRNA was exclusive to ATDC5 cells at their undifferentiated stage. None of ATDC5 cells at their differentiated stage and adult mice tissues examined expressed A-C2 gene. (+info)Reciprocal control of T helper cell and dendritic cell differentiation. (7/16085)
It is not known whether subsets of dendritic cells provide different cytokine microenvironments that determine the differentiation of either type-1 T helper (TH1) or TH2 cells. Human monocyte (pDC1)-derived dendritic cells (DC1) were found to induce TH1 differentiation, whereas dendritic cells (DC2) derived from CD4+CD3-CD11c- plasmacytoid cells (pDC2) induced TH2 differentiation by use of a mechanism unaffected by interleukin-4 (IL-4) or IL-12. The TH2 cytokine IL-4 enhanced DC1 maturation and killed pDC2, an effect potentiated by IL-10 but blocked by CD40 ligand and interferon-gamma. Thus, a negative feedback loop from the mature T helper cells may selectively inhibit prolonged TH1 or TH2 responses by regulating survival of the appropriate dendritic cell subset. (+info)Endothelial cells modulate the proliferation of mural cell precursors via platelet-derived growth factor-BB and heterotypic cell contact. (8/16085)
Embryological data suggest that endothelial cells (ECs) direct the recruitment and differentiation of mural cell precursors. We have developed in vitro coculture systems to model some of these events and have shown that ECs direct the migration of undifferentiated mesenchymal cells (10T1/2 cells) and induce their differentiation toward a smooth muscle cell/pericyte lineage. The present study was undertaken to investigate cell proliferation in these cocultures. ECs and 10T1/2 cells were cocultured in an underagarose assay in the absence of contact. There was a 2-fold increase in bromodeoxyuridine labeling of 10T1/2 cells in response to ECs, which was completely inhibited by the inclusion of neutralizing antiserum against platelet-derived growth factor (PDGF)-B. Antisera against PDGF-A, basic fibroblast growth factor, or transforming growth factor (TGF)-beta had no effect on EC-stimulated 10T1/2 cell proliferation. EC proliferation was not influenced by coculture with 10T1/2 cells in the absence of contact. The cells were then cocultured so that contact was permitted. Double labeling and fluorescence-activated cell sorter analysis revealed that ECs and 10T1/2 cells were growth-inhibited by 43% and 47%, respectively. Conditioned media from contacting EC-10T1/2 cell cocultures inhibited the growth of both cell types by 61% and 48%, respectively. Although we have previously shown a role for TGF-beta in coculture-induced mural cell differentiation, growth inhibition resulting from contacting cocultures or conditioned media was not suppressed by the presence of neutralizing antiserum against TGF-beta. Furthermore, the decreased proliferation of 10T1/2 cells in the direct cocultures could not be attributed to downregulation of the PDGF-B in ECs or the PDGF receptor-beta in the 10T1/2 cells. Our data suggest that modulation of proliferation occurs during EC recruitment of mesenchymal cells and that heterotypic cell-cell contact and soluble factors play a role in growth control during vessel assembly. (+info)Stem cell factor (SCF) is a protein that plays a crucial role in the development and maintenance of blood cells. It is also known as c-kit ligand because it binds to a protein called c-kit, which is found on the surface of certain types of cells, including hematopoietic stem cells. SCF is produced by a variety of cells, including endothelial cells, fibroblasts, and macrophages, and it acts as a growth factor for hematopoietic stem cells. It promotes the proliferation and differentiation of these cells, leading to the production of various types of blood cells, including red blood cells, white blood cells, and platelets. In addition to its role in hematopoiesis, SCF has been implicated in a variety of other biological processes, including angiogenesis, wound healing, and immune function. It has also been studied for its potential therapeutic applications in the treatment of various diseases, including cancer, anemia, and bone marrow failure.
Octamer Transcription Factor-3 (Oct3/4) is a transcription factor that plays a crucial role in the regulation of gene expression during embryonic development and stem cell maintenance. It is a member of the POU family of transcription factors, which are characterized by a conserved DNA-binding domain called the POU domain. Oct3/4 is expressed in the inner cell mass of the blastocyst, which gives rise to the embryo proper, and in the embryonic stem cells that can differentiate into all cell types of the body. It is also expressed in some adult tissues, such as the brain and testes. In stem cells, Oct3/4 is essential for maintaining their self-renewal capacity and pluripotency, which allows them to differentiate into any cell type in the body. It does this by binding to specific DNA sequences called Octamer boxes, which are located in the promoter regions of genes that are important for stem cell maintenance and differentiation. In addition to its role in stem cells, Oct3/4 has also been implicated in the development of various diseases, including cancer. For example, some cancer cells can reprogram themselves to express Oct3/4, which allows them to evade immune surveillance and continue to grow and divide uncontrollably. Therefore, targeting Oct3/4 may be a promising strategy for the treatment of certain types of cancer.
SOXB1 transcription factors are a family of proteins that play a crucial role in regulating gene expression in various biological processes, including development, differentiation, and homeostasis. The SOXB1 family includes three members: SOX9, SOX8, and SOX10. SOX9 is primarily expressed in the developing testis and is essential for the development of male sexual characteristics. It also plays a role in the development of the skeleton, cartilage, and bone. SOX8 is expressed in a variety of tissues, including the brain, heart, and skeletal muscle. It is involved in the regulation of cell proliferation and differentiation, as well as the development of the nervous system. SOX10 is expressed in neural crest cells, which give rise to a variety of cell types, including melanocytes, Schwann cells, and neurons. It is involved in the development of the peripheral nervous system, as well as the development of the skin and eyes. Mutations in SOXB1 transcription factors have been associated with a variety of human diseases, including developmental disorders, cancers, and neurological disorders. Understanding the function of these transcription factors is important for developing new treatments for these diseases.
Proto-oncogene proteins c-kit, also known as CD117 or c-Kit, are a family of receptor tyrosine kinases that play a critical role in cell growth, differentiation, and survival. They are expressed on various types of cells, including hematopoietic cells, mast cells, and interstitial cells of Cajal in the gastrointestinal tract. In the context of cancer, mutations in the c-kit gene can lead to the activation of the protein, resulting in uncontrolled cell growth and the development of tumors. This is particularly relevant in gastrointestinal stromal tumors (GISTs), which are the most common type of mesenchymal tumor of the gastrointestinal tract. GISTs often express high levels of c-kit, and targeted therapy with drugs that inhibit the activity of the protein has been shown to be effective in treating these tumors. Overall, the study of c-kit and its role in cancer has important implications for the development of new treatments for various types of malignancies.
Nestin is a type of intermediate filament protein that is expressed in various types of stem cells, including neural stem cells, muscle stem cells, and hematopoietic stem cells. It is a marker of neural progenitor cells and is often used to identify and isolate these cells for research and therapeutic purposes. In the medical field, Nestin is also used as a diagnostic tool to identify certain types of tumors, such as gliomas and neuroblastomas, which often express high levels of Nestin. Additionally, Nestin has been shown to play a role in the development and maintenance of neural stem cells, making it a potential target for therapies aimed at promoting neural regeneration and repair.
Homeodomain proteins are a class of transcription factors that play a crucial role in the development and differentiation of cells and tissues in animals. They are characterized by a highly conserved DNA-binding domain called the homeodomain, which allows them to recognize and bind to specific DNA sequences. Homeodomain proteins are involved in a wide range of biological processes, including embryonic development, tissue differentiation, and organogenesis. They regulate the expression of genes that are essential for these processes by binding to specific DNA sequences and either activating or repressing the transcription of target genes. There are many different types of homeodomain proteins, each with its own unique function and target genes. Some examples of homeodomain proteins include the Hox genes, which are involved in the development of the body plan in animals, and the Pax genes, which are involved in the development of the nervous system. Mutations in homeodomain proteins can lead to a variety of developmental disorders, including congenital malformations and intellectual disabilities. Understanding the function and regulation of homeodomain proteins is therefore important for the development of new treatments for these conditions.
Transcription factors are proteins that regulate gene expression by binding to specific DNA sequences and controlling the transcription of genetic information from DNA to RNA. They play a crucial role in the development and function of cells and tissues in the body. In the medical field, transcription factors are often studied as potential targets for the treatment of diseases such as cancer, where their activity is often dysregulated. For example, some transcription factors are overexpressed in certain types of cancer cells, and inhibiting their activity may help to slow or stop the growth of these cells. Transcription factors are also important in the development of stem cells, which have the ability to differentiate into a wide variety of cell types. By understanding how transcription factors regulate gene expression in stem cells, researchers may be able to develop new therapies for diseases such as diabetes and heart disease. Overall, transcription factors are a critical component of gene regulation and have important implications for the development and treatment of many diseases.
Green Fluorescent Proteins (GFPs) are a class of proteins that emit green light when excited by blue or ultraviolet light. They were first discovered in the jellyfish Aequorea victoria and have since been widely used as a tool in the field of molecular biology and bioimaging. In the medical field, GFPs are often used as a marker to track the movement and behavior of cells and proteins within living organisms. For example, scientists can insert a gene for GFP into a cell or organism, allowing them to visualize the cell or protein in real-time using a fluorescent microscope. This can be particularly useful in studying the development and function of cells, as well as in the diagnosis and treatment of diseases. GFPs have also been used to develop biosensors, which can detect the presence of specific molecules or changes in cellular environment. For example, researchers have developed GFP-based sensors that can detect the presence of certain drugs or toxins, or changes in pH or calcium levels within cells. Overall, GFPs have become a valuable tool in the medical field, allowing researchers to study cellular processes and diseases in new and innovative ways.
A teratoma is a type of tumor that is composed of multiple types of tissue, including bone, cartilage, fat, and neural tissue. It is also known as a "mixed germ cell tumor" because it is derived from primitive cells that have the potential to develop into any type of tissue in the body. Teratomas are most commonly found in the ovaries, testes, and brain, but they can occur in any part of the body. They are usually benign, meaning they are not cancerous, but in some cases they can be malignant and may require treatment. Teratomas are often diagnosed through imaging tests such as ultrasound or MRI, and a biopsy may be performed to confirm the diagnosis. Treatment for teratomas depends on the size and location of the tumor, as well as whether it is benign or malignant. In some cases, surgery may be necessary to remove the tumor, and in other cases, chemotherapy or radiation therapy may be used to treat the tumor.
Graft-versus-host disease (GVHD) is a condition that can occur after a bone marrow or stem cell transplant. It happens when the transplanted cells (the graft) attack the recipient's (the host) tissues and organs. This can cause a range of symptoms, including skin rash, diarrhea, liver problems, and inflammation of the lungs, gut, and blood vessels. GVHD can be a serious and potentially life-threatening complication of transplantation, but it can also be treated with medications and other therapies.
Granulocyte Colony-Stimulating Factor (G-CSF) is a protein that stimulates the production and differentiation of granulocytes (a type of white blood cell) in the bone marrow. It is primarily used to treat neutropenia (a condition characterized by a low number of neutrophils in the blood), which can occur as a side effect of chemotherapy or radiation therapy for cancer, or as a result of certain infections or autoimmune disorders. G-CSF is typically administered as a daily injection for several days, and it works by binding to specific receptors on the surface of bone marrow cells, which triggers a signaling cascade that leads to the production and release of granulocytes into the bloodstream. This helps to increase the number of neutrophils in the blood and reduce the risk of infection. In addition to its use in treating neutropenia, G-CSF has also been studied for its potential use in other medical conditions, such as bone marrow transplantation, chronic granulomatous disease, and some types of anemia. However, more research is needed to determine its effectiveness and safety in these settings.
CD24 is a type of antigen, which is a molecule that is present on the surface of cells and can be recognized by the immune system. CD24 is a transmembrane glycoprotein that is expressed on a variety of cells, including epithelial cells, endothelial cells, and immune cells. It is also known as sialomucin or cluster of differentiation 24. CD24 plays a role in cell adhesion and signaling, and it has been implicated in a number of different biological processes, including cell proliferation, differentiation, and migration. It is also involved in the regulation of immune responses, and it has been shown to play a role in the development and function of various immune cells, including T cells, B cells, and dendritic cells. In the medical field, CD24 is often studied in the context of cancer. It has been found to be overexpressed in a number of different types of cancer, including breast cancer, ovarian cancer, and lung cancer. This overexpression has been associated with poor prognosis and increased risk of recurrence. As a result, CD24 has been proposed as a potential target for cancer therapy, and there are ongoing efforts to develop drugs that can specifically target CD24 on cancer cells.
Hematologic neoplasms are a group of disorders that affect the blood and bone marrow, including the production of blood cells. These disorders are characterized by the abnormal growth and proliferation of blood cells, which can lead to an overproduction of certain types of blood cells (such as leukemias) or a deficiency of certain types of blood cells (such as anemia). Hematologic neoplasms can be either benign (non-cancerous) or malignant (cancerous), and they can affect people of all ages. Some common types of hematologic neoplasms include leukemia, lymphoma, multiple myeloma, and myelodysplastic syndromes. Treatment for hematologic neoplasms typically involves a combination of chemotherapy, radiation therapy, and/or stem cell transplantation.
Receptors, Notch are a family of cell surface receptors that play a critical role in cell fate determination, differentiation, proliferation, and apoptosis in various tissues and organs during embryonic development and in adult organisms. The Notch signaling pathway is activated by binding of a ligand, such as Delta or Jagged, to the extracellular domain of the Notch receptor, leading to a series of intracellular events that ultimately regulate gene expression and cellular behavior. Dysregulation of Notch signaling has been implicated in a variety of human diseases, including cancer, cardiovascular disease, and neurodegenerative disorders.
In the medical field, RNA, Messenger (mRNA) refers to a type of RNA molecule that carries genetic information from DNA in the nucleus of a cell to the ribosomes, where proteins are synthesized. During the process of transcription, the DNA sequence of a gene is copied into a complementary RNA sequence called messenger RNA (mRNA). This mRNA molecule then leaves the nucleus and travels to the cytoplasm of the cell, where it binds to ribosomes and serves as a template for the synthesis of a specific protein. The sequence of nucleotides in the mRNA molecule determines the sequence of amino acids in the protein that is synthesized. Therefore, changes in the sequence of nucleotides in the mRNA molecule can result in changes in the amino acid sequence of the protein, which can affect the function of the protein and potentially lead to disease. mRNA molecules are often used in medical research and therapy as a way to introduce new genetic information into cells. For example, mRNA vaccines work by introducing a small piece of mRNA that encodes for a specific protein, which triggers an immune response in the body.
Intermediate filament proteins (IFPs) are a type of cytoskeletal protein that provide structural support to cells. They are found in all types of cells, including epithelial cells, muscle cells, and nerve cells. IFPs are composed of multiple subunits that form long, fibrous polymers that are arranged in a helical structure. These filaments are intermediate in size between the microfilaments and microtubules, which are other types of cytoskeletal proteins. IFPs play a number of important roles in cells, including maintaining cell shape, providing mechanical strength, and anchoring organelles in place. They are also involved in a variety of cellular processes, such as cell division, migration, and differentiation.
Wnt proteins are a family of signaling molecules that play a crucial role in regulating cell proliferation, differentiation, migration, and survival. They are secreted by cells and bind to receptors on the surface of neighboring cells, activating a signaling cascade that regulates gene expression and cellular behavior. In the medical field, Wnt proteins are of great interest because they are involved in a wide range of diseases and conditions, including cancer, developmental disorders, and neurodegenerative diseases. For example, mutations in Wnt signaling pathways have been implicated in the development of colorectal cancer, and dysregulated Wnt signaling has been linked to the progression of other types of cancer as well. Wnt proteins are also being studied as potential therapeutic targets for a variety of diseases. For example, drugs that target Wnt signaling have shown promise in preclinical studies for the treatment of cancer, and there is ongoing research into the use of Wnt signaling inhibitors for the treatment of other conditions, such as inflammatory bowel disease and osteoporosis.
In the medical field, "Disease Models, Animal" refers to the use of animals to study and understand human diseases. These models are created by introducing a disease or condition into an animal, either naturally or through experimental manipulation, in order to study its progression, symptoms, and potential treatments. Animal models are used in medical research because they allow scientists to study diseases in a controlled environment and to test potential treatments before they are tested in humans. They can also provide insights into the underlying mechanisms of a disease and help to identify new therapeutic targets. There are many different types of animal models used in medical research, including mice, rats, rabbits, dogs, and monkeys. Each type of animal has its own advantages and disadvantages, and the choice of model depends on the specific disease being studied and the research question being addressed.
Hematopoietic cell growth factors (HCGFs) are a group of proteins that regulate the growth, differentiation, and survival of hematopoietic stem cells and their progeny, which include all types of blood cells. These factors are produced by a variety of cells, including stromal cells, endothelial cells, and immune cells, and act on hematopoietic cells through specific receptors on their surface. HCGFs play a critical role in the maintenance of the hematopoietic system, which is responsible for producing all of the blood cells in the body. They are also important in the treatment of certain blood disorders, such as anemia, leukemia, and lymphoma, by promoting the growth and differentiation of blood cells. Some examples of HCGFs include erythropoietin (EPO), granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), and thrombopoietin (TPO). These factors are often used in the clinic to stimulate the production of specific types of blood cells, such as red blood cells, white blood cells, or platelets, in patients with low blood counts or other hematological disorders.
Cell transformation, neoplastic refers to the process by which normal cells in the body undergo genetic changes that cause them to become cancerous or malignant. This process involves the accumulation of mutations in genes that regulate cell growth, division, and death, leading to uncontrolled cell proliferation and the formation of tumors. Neoplastic transformation can occur in any type of cell in the body, and it can be caused by a variety of factors, including exposure to carcinogens, radiation, viruses, and inherited genetic mutations. Once a cell has undergone neoplastic transformation, it can continue to divide and grow uncontrollably, invading nearby tissues and spreading to other parts of the body through the bloodstream or lymphatic system. The diagnosis of neoplastic transformation typically involves a combination of clinical examination, imaging studies, and biopsy. Treatment options for neoplastic transformation depend on the type and stage of cancer, as well as the patient's overall health and preferences. Common treatments include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy.
Nerve tissue proteins are proteins that are found in nerve cells, also known as neurons. These proteins play important roles in the structure and function of neurons, including the transmission of electrical signals along the length of the neuron and the communication between neurons. There are many different types of nerve tissue proteins, each with its own specific function. Some examples of nerve tissue proteins include neurofilaments, which provide structural support for the neuron; microtubules, which help to maintain the shape of the neuron and transport materials within the neuron; and neurofilament light chain, which is involved in the formation of neurofibrillary tangles, which are a hallmark of certain neurodegenerative diseases such as Alzheimer's disease. Nerve tissue proteins are important for the proper functioning of the nervous system and any disruption in their production or function can lead to neurological disorders.
CD44 is a cell surface glycoprotein that is expressed on many different types of cells, including immune cells, epithelial cells, and cancer cells. It is a member of the immunoglobulin superfamily of cell adhesion molecules and plays a role in cell-cell interactions, cell migration, and signaling. In the context of the immune system, CD44 is a receptor for hyaluronic acid, a large glycosaminoglycan that is found in the extracellular matrix.

In the medical field, IL-11 has been studied for its potential therapeutic applications in various diseases, including cancer, inflammatory bowel disease, and anemia. It has been shown to promote the growth of certain types of cancer cells, and may be useful in treating certain types of anemia by stimulating the production of red blood cells. However, further research is needed to fully understand the potential benefits and risks of using IL-11 as a therapeutic agent.
In the medical field, a nodal protein is a type of signaling protein that plays a crucial role in the development and differentiation of cells. Nodal proteins are members of the transforming growth factor-beta (TGF-beta) superfamily and are involved in the regulation of various cellular processes, including cell proliferation, migration, and differentiation. Nodal proteins are particularly important during embryonic development, where they help to establish the body plan and determine the fate of different cell types. They are also involved in the development of various organs and tissues, including the heart, lungs, and limbs. In the context of cancer, nodal proteins have been implicated in the development and progression of various types of tumors. For example, overexpression of nodal proteins has been associated with the development of breast cancer, ovarian cancer, and other types of cancer. Overall, nodal proteins are important signaling molecules that play a critical role in the development and function of various tissues and organs in the body.
Hepatic Veno-Occlusive Disease (VOD) is a rare but serious condition that affects the liver. It is also known as sinusoidal obstruction syndrome (SOS) or veno-occlusive disease of the liver (VOD/L). VOD occurs when the small blood vessels in the liver (sinusoids) become blocked or narrowed, leading to liver damage and dysfunction. VOD can be caused by a variety of factors, including chemotherapy, radiation therapy, stem cell transplantation, and exposure to certain toxins or medications. The symptoms of VOD can include jaundice, abdominal pain, nausea, vomiting, fatigue, and loss of appetite. In severe cases, VOD can lead to liver failure and death. Treatment for VOD typically involves managing the symptoms and addressing the underlying cause of the condition. This may include medications to reduce inflammation and improve liver function, as well as supportive care to manage symptoms and prevent complications. In some cases, a liver transplant may be necessary to restore liver function.
Proteins are complex biomolecules made up of amino acids that play a crucial role in many biological processes in the human body. In the medical field, proteins are studied extensively as they are involved in a wide range of functions, including: 1. Enzymes: Proteins that catalyze chemical reactions in the body, such as digestion, metabolism, and energy production. 2. Hormones: Proteins that regulate various bodily functions, such as growth, development, and reproduction. 3. Antibodies: Proteins that help the immune system recognize and neutralize foreign substances, such as viruses and bacteria. 4. Transport proteins: Proteins that facilitate the movement of molecules across cell membranes, such as oxygen and nutrients. 5. Structural proteins: Proteins that provide support and shape to cells and tissues, such as collagen and elastin. Protein abnormalities can lead to various medical conditions, such as genetic disorders, autoimmune diseases, and cancer. Therefore, understanding the structure and function of proteins is essential for developing effective treatments and therapies for these conditions.
Fusion proteins, specifically BCR-ABL, are a type of abnormal protein that occurs as a result of a genetic mutation in certain types of leukemia and other blood disorders. The BCR-ABL fusion protein is formed when two separate genes, BCR (breakpoint cluster region) and ABL (abelson murine leukemia virus), fuse together and become a single gene. This fusion gene is then expressed as a single protein, which is known as BCR-ABL. BCR-ABL is a tyrosine kinase, which is an enzyme that is involved in regulating cell growth and division. In the case of BCR-ABL, the abnormal activity of the fusion protein leads to uncontrolled cell growth and division, which can result in the development of leukemia or other blood disorders. BCR-ABL is typically diagnosed through a blood test that detects the presence of the fusion protein in the blood. Treatment for BCR-ABL-positive leukemia typically involves the use of targeted therapies, such as tyrosine kinase inhibitors, which are designed to specifically block the activity of the BCR-ABL fusion protein and prevent it from promoting uncontrolled cell growth and division.
In the medical field, "RNA, Untranslated" refers to a type of RNA molecule that does not code for a functional protein. These molecules are often referred to as non-coding RNA (ncRNA) and can play important roles in regulating gene expression and other cellular processes. There are several types of untranslated RNA, including microRNAs (miRNAs), small interfering RNAs (siRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs). These molecules can interact with messenger RNA (mRNA) molecules to regulate gene expression by blocking the translation of mRNA into protein or by promoting the degradation of the mRNA. Untranslated RNA molecules have been implicated in a wide range of diseases, including cancer, neurological disorders, and infectious diseases. Understanding the function and regulation of these molecules is an active area of research in the field of molecular biology and has the potential to lead to the development of new therapeutic strategies for these diseases.

- The principal investigator on this seminal fasting/stem cell study in mice, Ömer H. Yilmaz, M.D., Ph.D., shared the possible future implications on his research, that "fasting has many effects in the intestine, which included boosting regeneration as well as potential uses in any type of ailment that impinges on the intestine, such as infections or cancers. (mindbodygreen.com)
- This paper gives an Islamic perspective on some of these advances, including abortion, in vitro fertilization, genetic engineering, cloning and stem cell research. (who.int)
Patients2
- Likewise, in asplenic ALPS patients with, stress the infection risks, including the pneumococcal sepsis associated with asplenia (which may be compounded by lack of memory B cells and autoimmune neutropenia). (medscape.com)
- Because of deficient memory B-cell function, these patients are often unable to produce or maintain protective antibodies against polysaccharide antigens after vaccination. (medscape.com)
Infection1
- One concern about the procedure is that immune cells in cord blood do not have experience with the viruses responsible for latent infections, leading to a higher percentage of naive T cells and thus increased vulnerability to reactivation of cytomegalovirus or Epstein-Barr virus infection. (msdmanuals.com)
Infusion1
- Stem cell infusion is a relatively simple process that is performed at the bedside. (medscape.com)
Tumor2
- As an HuR/mRNA disruptor, KH-3 treatment successfully mimicked the effects of HuR knockdown in pancreatic cancer cell lines: KH-3 significantly inhibited pancreatic cancer cell migration, invasion, tumor sphere formation and EMT. (ku.edu)
- The CSC is defined as a cancer cell with self-renewing capacity that can regenerate the original tumor in all its differentiated heterogeneity. (medscape.com)
Type2
- When a stem cell divides, each "daughter" cell has the potential to either remain a stem cell or become another type of cell with a more specialized function, such as a heart muscle cell, a red blood cell, or a brain cell. (mindbodygreen.com)
- In order to examine a particular cell type, one must first be able to clearly distinguish it from others. (analytica-world.com)
Immune system2
- Although mice may show changes in stem cell function after just 24 hours, in humans, studies indicate prolonged fasts (several days) may be used to trigger stem-cell-based regeneration that rejuvenates the immune system. (mindbodygreen.com)
- Rheumatoid arthritis (RA) is an autoimmune and inflammatory disease that occurs when a person's immune system attacks healthy cells in the body. (medicaldaily.com)
Human6
- Jensen, K. B. & Watt, F. M. Single-cell expression profiling of human epidermal stem and transit-amplifying cells: Lrig1 is a regulator of stem cell quiescence. (nature.com)
- Recombinant human GM-CSF (rhGM-CSF) promotes the production of myeloid cells of the granulocytic (neutrophils, eosinophils and basophils) and monocytic lineages in vivo. (stemcell.com)
- Human adult mobilized CD34+ cells were cultured for 21 days under normoxia (21% O 2 ) or hypoxia (2% O 2 ) in vessels coated with optimized concentrations of Delta1. (confex.com)
- To corroborate these findings molecularly, we performed transcriptomic analyses and found significant upregulation of a distinct HSC gene expression signature in cells cultured with Delta1 in hypoxia (Fig. A). Collectively, these data show that hypoxia supports a superior ex vivo expansion of human HSCs with LTR activity compared with normoxia at optimized densities of Delta1. (confex.com)
- Based on established in vivo doses that induce significant pulmonary disorders, physiologically relevant in vitro doses (i.e., 0.02 - 0.2 microg/cm2) of NPs, including carbon nanotube s (CNTs) and iron oxide NPs (nFe2O3), were used to evaluate their toxic effects on human lung cells under long-term exposure condition (up to 6.5 months). (cdc.gov)
- Present study data showed that NPs were able to induce dose- and time-dependent cytotoxicity, inflammation, fibrogenesis and neoplastic transformation of human lung cells, consistent with in vivo data. (cdc.gov)
Declines2
- As we age, stem cell activity naturally declines, accelerating the aging process. (expertclick.com)
- The study has profound implications for promoting healthier aging processes, as immune cell function and protection from disease declines with age. (mindbodygreen.com)
