Gene knockout techniques. Medical search

Techniques to alter a gene sequence that result in an inactivated gene, or one in which the expression can be inactivated at a chosen time during development to study the loss of function of a gene.

Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

Inbred C57BL mice are a strain of laboratory mice that have been produced by many generations of brother-sister matings, resulting in a high degree of genetic uniformity and homozygosity, making them widely used for biomedical research, including studies on genetics, immunology, cancer, and neuroscience.

The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

A species of halophilic archaea found in the Dead Sea.

RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.

Probabilistic protein function prediction from heterogeneous genome-wide data. (1/2316)

Dramatic improvements in high throughput sequencing technologies have led to a staggering growth in the number of predicted genes. However, a large fraction of these newly discovered genes do not have a functional assignment. Fortunately, a variety of novel high-throughput genome-wide functional screening technologies provide important clues that shed light on gene function. The integration of heterogeneous data to predict protein function has been shown to improve the accuracy of automated gene annotation systems. In this paper, we propose and evaluate a probabilistic approach for protein function prediction that integrates protein-protein interaction (PPI) data, gene expression data, protein motif information, mutant phenotype data, and protein localization data. First, functional linkage graphs are constructed from PPI data and gene expression data, in which an edge between nodes (proteins) represents evidence for functional similarity. The assumption here is that graph neighbors are more likely to share protein function, compared to proteins that are not neighbors. The functional linkage graph model is then used in concert with protein domain, mutant phenotype and protein localization data to produce a functional prediction. Our method is applied to the functional prediction of Saccharomyces cerevisiae genes, using Gene Ontology (GO) terms as the basis of our annotation. In a cross validation study we show that the integrated model increases recall by 18%, compared to using PPI data alone at the 50% precision. We also show that the integrated predictor is significantly better than each individual predictor. However, the observed improvement vs. PPI depends on both the new source of data and the functional category to be predicted. Surprisingly, in some contexts integration hurts overall prediction accuracy. Lastly, we provide a comprehensive assignment of putative GO terms to 463 proteins that currently have no assigned function. (+info)

"Gene knockout techniques" refer to a group of biomedical research methods used in genetics and molecular biology to study the function of specific genes in an organism. These techniques involve introducing a deliberate, controlled genetic modification that results in the inactivation or "knockout" of a particular gene. This is typically achieved through various methods such as homologous recombination, where a modified version of the gene with inserted mutations is introduced into the organism's genome, replacing the original functional gene. The resulting organism, known as a "knockout mouse" or other model organisms, lacks the function of the targeted gene and can be used to study its role in biological processes, disease development, and potential therapeutic interventions.

A "knockout" mouse is a genetically engineered mouse in which one or more genes have been deleted or "knocked out" using molecular biology techniques. This allows researchers to study the function of specific genes and their role in various biological processes, as well as potential associations with human diseases. The mice are generated by introducing targeted DNA modifications into embryonic stem cells, which are then used to create a live animal. Knockout mice have been widely used in biomedical research to investigate gene function, disease mechanisms, and potential therapeutic targets.

C57BL/6 (C57 Black 6) is an inbred strain of laboratory mouse that is widely used in biomedical research. The term "inbred" refers to a strain of animals where matings have been carried out between siblings or other closely related individuals for many generations, resulting in a population that is highly homozygous at most genetic loci.

The C57BL/6 strain was established in 1920 by crossing a female mouse from the dilute brown (DBA) strain with a male mouse from the black strain. The resulting offspring were then interbred for many generations to create the inbred C57BL/6 strain.

C57BL/6 mice are known for their robust health, longevity, and ease of handling, making them a popular choice for researchers. They have been used in a wide range of biomedical research areas, including studies of cancer, immunology, neuroscience, cardiovascular disease, and metabolism.

One of the most notable features of the C57BL/6 strain is its sensitivity to certain genetic modifications, such as the introduction of mutations that lead to obesity or impaired glucose tolerance. This has made it a valuable tool for studying the genetic basis of complex diseases and traits.

Overall, the C57BL/6 inbred mouse strain is an important model organism in biomedical research, providing a valuable resource for understanding the genetic and molecular mechanisms underlying human health and disease.

Gene targeting is a research technique in molecular biology used to precisely modify specific genes within the genome of an organism. This technique allows scientists to study gene function by creating targeted genetic changes, such as insertions, deletions, or mutations, in a specific gene of interest. The process typically involves the use of engineered nucleases, such as CRISPR-Cas9 or TALENs, to introduce double-stranded breaks at desired locations within the genome. These breaks are then repaired by the cell's own DNA repair machinery, often leading to the incorporation of designed changes in the targeted gene. Gene targeting is a powerful tool for understanding gene function and has wide-ranging applications in basic research, agriculture, and therapeutic development.

Gene deletion is a type of mutation where a segment of DNA, containing one or more genes, is permanently lost or removed from a chromosome. This can occur due to various genetic mechanisms such as homologous recombination, non-homologous end joining, or other types of genomic rearrangements.

The deletion of a gene can have varying effects on the organism, depending on the function of the deleted gene and its importance for normal physiological processes. If the deleted gene is essential for survival, the deletion may result in embryonic lethality or developmental abnormalities. However, if the gene is non-essential or has redundant functions, the deletion may not have any noticeable effects on the organism's phenotype.

Gene deletions can also be used as a tool in genetic research to study the function of specific genes and their role in various biological processes. For example, researchers may use gene deletion techniques to create genetically modified animal models to investigate the impact of gene deletion on disease progression or development.

Metabolic engineering is a branch of biotechnology that involves the modification and manipulation of metabolic pathways in organisms to enhance their production of specific metabolites or to alter their flow of energy and carbon. This field combines principles from genetics, molecular biology, biochemistry, and chemical engineering to design and construct novel metabolic pathways or modify existing ones with the goal of optimizing the production of valuable compounds or improving the properties of organisms for various applications.

Examples of metabolic engineering include the modification of microorganisms to produce biofuels, pharmaceuticals, or industrial chemicals; the enhancement of crop yields and nutritional value in agriculture; and the development of novel bioremediation strategies for environmental pollution control. The ultimate goal of metabolic engineering is to create organisms that can efficiently and sustainably produce valuable products while minimizing waste and reducing the impact on the environment.

Animal disease models are specialized animals, typically rodents such as mice or rats, that have been genetically engineered or exposed to certain conditions to develop symptoms and physiological changes similar to those seen in human diseases. These models are used in medical research to study the pathophysiology of diseases, identify potential therapeutic targets, test drug efficacy and safety, and understand disease mechanisms.

The genetic modifications can include knockout or knock-in mutations, transgenic expression of specific genes, or RNA interference techniques. The animals may also be exposed to environmental factors such as chemicals, radiation, or infectious agents to induce the disease state.

Examples of animal disease models include:

1. Mouse models of cancer: Genetically engineered mice that develop various types of tumors, allowing researchers to study cancer initiation, progression, and metastasis.
2. Alzheimer's disease models: Transgenic mice expressing mutant human genes associated with Alzheimer's disease, which exhibit amyloid plaque formation and cognitive decline.
3. Diabetes models: Obese and diabetic mouse strains like the NOD (non-obese diabetic) or db/db mice, used to study the development of type 1 and type 2 diabetes, respectively.
4. Cardiovascular disease models: Atherosclerosis-prone mice, such as ApoE-deficient or LDLR-deficient mice, that develop plaque buildup in their arteries when fed a high-fat diet.
5. Inflammatory bowel disease models: Mice with genetic mutations affecting intestinal barrier function and immune response, such as IL-10 knockout or SAMP1/YitFc mice, which develop colitis.

Animal disease models are essential tools in preclinical research, but it is important to recognize their limitations. Differences between species can affect the translatability of results from animal studies to human patients. Therefore, researchers must carefully consider the choice of model and interpret findings cautiously when applying them to human diseases.

A phenotype is the physical or biochemical expression of an organism's genes, or the observable traits and characteristics resulting from the interaction of its genetic constitution (genotype) with environmental factors. These characteristics can include appearance, development, behavior, and resistance to disease, among others. Phenotypes can vary widely, even among individuals with identical genotypes, due to differences in environmental influences, gene expression, and genetic interactions.

Transgenic mice are genetically modified rodents that have incorporated foreign DNA (exogenous DNA) into their own genome. This is typically done through the use of recombinant DNA technology, where a specific gene or genetic sequence of interest is isolated and then introduced into the mouse embryo. The resulting transgenic mice can then express the protein encoded by the foreign gene, allowing researchers to study its function in a living organism.

The process of creating transgenic mice usually involves microinjecting the exogenous DNA into the pronucleus of a fertilized egg, which is then implanted into a surrogate mother. The offspring that result from this procedure are screened for the presence of the foreign DNA, and those that carry the desired genetic modification are used to establish a transgenic mouse line.

Transgenic mice have been widely used in biomedical research to model human diseases, study gene function, and test new therapies. They provide a valuable tool for understanding complex biological processes and developing new treatments for a variety of medical conditions.

Genetic engineering, also known as genetic modification, is a scientific process where the DNA or genetic material of an organism is manipulated to bring about a change in its characteristics. This is typically done by inserting specific genes into the organism's genome using various molecular biology techniques. These new genes may come from the same species (cisgenesis) or a different species (transgenesis). The goal is to produce a desired trait, such as resistance to pests, improved nutritional content, or increased productivity. It's widely used in research, medicine, and agriculture. However, it's important to note that the use of genetically engineered organisms can raise ethical, environmental, and health concerns.

Integrases are enzymes that are responsible for the integration of genetic material into a host's DNA. In particular, integrases play a crucial role in the life cycle of retroviruses, such as HIV (Human Immunodeficiency Virus). These viruses have an RNA genome, which must be reverse-transcribed into DNA before it can be integrated into the host's chromosomal DNA.

The integrase enzyme, encoded by the virus's pol gene, is responsible for this critical step in the retroviral replication cycle. It mediates the cutting and pasting of the viral cDNA into a specific site within the host cell's genome, leading to the formation of a provirus. This provirus can then be transcribed and translated by the host cell's machinery, resulting in the production of new virus particles.

Integrase inhibitors are an important class of antiretroviral drugs used in the treatment of HIV infection. They work by blocking the activity of the integrase enzyme, thereby preventing the integration of viral DNA into the host genome and halting the replication of the virus.

"Essential genes" refer to a category of genes that are vital for the survival or reproduction of an organism. They encode proteins that are necessary for fundamental biological processes, such as DNA replication, transcription, translation, and cell division. Mutations in essential genes often result in lethality or infertility, making them indispensable for the organism's existence. The identification and study of essential genes can provide valuable insights into the basic mechanisms of life and disease.

Molecular sequence data refers to the specific arrangement of molecules, most commonly nucleotides in DNA or RNA, or amino acids in proteins, that make up a biological macromolecule. This data is generated through laboratory techniques such as sequencing, and provides information about the exact order of the constituent molecules. This data is crucial in various fields of biology, including genetics, evolution, and molecular biology, allowing for comparisons between different organisms, identification of genetic variations, and studies of gene function and regulation.

Signal transduction is the process by which a cell converts an extracellular signal, such as a hormone or neurotransmitter, into an intracellular response. This involves a series of molecular events that transmit the signal from the cell surface to the interior of the cell, ultimately resulting in changes in gene expression, protein activity, or metabolism.

The process typically begins with the binding of the extracellular signal to a receptor located on the cell membrane. This binding event activates the receptor, which then triggers a cascade of intracellular signaling molecules, such as second messengers, protein kinases, and ion channels. These molecules amplify and propagate the signal, ultimately leading to the activation or inhibition of specific cellular responses.

Signal transduction pathways are highly regulated and can be modulated by various factors, including other signaling molecules, post-translational modifications, and feedback mechanisms. Dysregulation of these pathways has been implicated in a variety of diseases, including cancer, diabetes, and neurological disorders.

I apologize for any confusion, but "Haloferax volcanii" is not a medical term or concept. It is actually a species of archaea (single-celled microorganisms) that is commonly found in extremely salty environments, such as salt lakes and salt mines. The name "Haloferax volcanii" refers to the fact that this organism is halophilic (salt-loving) and was first isolated from a volcanic site.

Here is a brief scientific definition of "Haloferax volcanii":

Haloferax volcanii is a species of halophilic archaea belonging to the family Haloferacaceae. It is a rod-shaped, motile organism that is commonly found in hypersaline environments such as salt lakes and salt mines. The optimum growth temperature for H. volcanii is around 45°C, and it can tolerate a wide range of salinities (up to 3 M NaCl). It has a relatively large genome (around 4 Mb) that contains many genes involved in DNA repair and stress response, making it well-adapted to life in extreme environments. H. volcanii is also known for its ability to form stable triparental mating structures, which are used in genetic studies of archaea.

Messenger RNA (mRNA) is a type of RNA (ribonucleic acid) that carries genetic information copied from DNA in the form of a series of three-base code "words," each of which specifies a particular amino acid. This information is used by the cell's machinery to construct proteins, a process known as translation. After being transcribed from DNA, mRNA travels out of the nucleus to the ribosomes in the cytoplasm where protein synthesis occurs. Once the protein has been synthesized, the mRNA may be degraded and recycled. Post-transcriptional modifications can also occur to mRNA, such as alternative splicing and addition of a 5' cap and a poly(A) tail, which can affect its stability, localization, and translation efficiency.

A mutation is a permanent change in the DNA sequence of an organism's genome. Mutations can occur spontaneously or be caused by environmental factors such as exposure to radiation, chemicals, or viruses. They may have various effects on the organism, ranging from benign to harmful, depending on where they occur and whether they alter the function of essential proteins. In some cases, mutations can increase an individual's susceptibility to certain diseases or disorders, while in others, they may confer a survival advantage. Mutations are the driving force behind evolution, as they introduce new genetic variability into populations, which can then be acted upon by natural selection.

'Gene expression regulation' refers to the processes that control whether, when, and where a particular gene is expressed, meaning the production of a specific protein or functional RNA encoded by that gene. This complex mechanism can be influenced by various factors such as transcription factors, chromatin remodeling, DNA methylation, non-coding RNAs, and post-transcriptional modifications, among others. Proper regulation of gene expression is crucial for normal cellular function, development, and maintaining homeostasis in living organisms. Dysregulation of gene expression can lead to various diseases, including cancer and genetic disorders.

"Cells, cultured" is a medical term that refers to cells that have been removed from an organism and grown in controlled laboratory conditions outside of the body. This process is called cell culture and it allows scientists to study cells in a more controlled and accessible environment than they would have inside the body. Cultured cells can be derived from a variety of sources, including tissues, organs, or fluids from humans, animals, or cell lines that have been previously established in the laboratory.

Cell culture involves several steps, including isolation of the cells from the tissue, purification and characterization of the cells, and maintenance of the cells in appropriate growth conditions. The cells are typically grown in specialized media that contain nutrients, growth factors, and other components necessary for their survival and proliferation. Cultured cells can be used for a variety of purposes, including basic research, drug development and testing, and production of biological products such as vaccines and gene therapies.

It is important to note that cultured cells may behave differently than they do in the body, and results obtained from cell culture studies may not always translate directly to human physiology or disease. Therefore, it is essential to validate findings from cell culture experiments using additional models and ultimately in clinical trials involving human subjects.

'Abbreviations as Topic' in medical terms refers to the use and interpretation of abbreviated words or phrases that are commonly used in the field of medicine. These abbreviations can represent various concepts, such as medical conditions, treatments, procedures, diagnostic tests, and more.

Medical abbreviations are often used in clinical documentation, including patient records, progress notes, orders, and medication administration records. They help healthcare professionals communicate efficiently and effectively, reducing the need for lengthy descriptions and improving clarity in written communication.

However, medical abbreviations can also be a source of confusion and error if they are misinterpreted or used incorrectly. Therefore, it is essential to use standardized abbreviations that are widely recognized and accepted within the medical community. Additionally, healthcare professionals should always ensure that their use of abbreviations does not compromise patient safety or lead to misunderstandings in patient care.

Examples of commonly used medical abbreviations include:

* PT: Physical Therapy
* BP: Blood Pressure
* HR: Heart Rate
* Rx: Prescription
* NPO: Nothing by Mouth
* IV: Intravenous
* IM: Intramuscular
* COPD: Chronic Obstructive Pulmonary Disease
* MI: Myocardial Infarction (Heart Attack)
* Dx: Diagnosis

It is important to note that some medical abbreviations can have multiple meanings, and their interpretation may depend on the context in which they are used. Therefore, it is essential to use caution when interpreting medical abbreviations and seek clarification if necessary to ensure accurate communication and patient care.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

Cobblestone lissencephaly is a type of brain malformation characterized by a smooth brain surface with no normal convolutions (gyri) or indentations (sulci). Instead, the brain surface has a pebbly or "cobblestone" appearance. This condition is caused by abnormal migration of nerve cells during fetal development.

In cobblestone lissencephaly, the nerve cells that should form the outer layer of the brain (the cerebral cortex) fail to migrate properly and instead accumulate in thick layers beneath the surface of the brain. This can lead to severe intellectual disability, seizures, muscle spasticity, vision problems, and other neurological issues.

Cobblestone lissencephaly is often associated with genetic disorders such as Walker-Warburg syndrome, Muscle-eye-brain disease, and Fukuyama congenital muscular dystrophy. It can also be seen in some cases of congenital infection or exposure to environmental toxins during pregnancy.

"Gene knock-in techniques" refer to a group of genetic engineering methods used in molecular biology to precisely insert or "knock-in" a specific gene or DNA sequence into a specific location within the genome of an organism. This is typically done using recombinant DNA technology and embryonic stem (ES) cells, although other techniques such as CRISPR-Cas9 can also be used.

The goal of gene knock-in techniques is to create a stable and heritable genetic modification in which the introduced gene is expressed at a normal level and in the correct spatial and temporal pattern. This allows researchers to study the function of individual genes, investigate gene regulation, model human diseases, and develop potential therapies for genetic disorders.

In general, gene knock-in techniques involve several steps: first, a targeting vector is constructed that contains the desired DNA sequence flanked by homologous regions that match the genomic locus where the insertion will occur. This vector is then introduced into ES cells, which are cultured and allowed to undergo homologous recombination with the endogenous genome. The resulting modified ES cells are selected for and characterized to confirm the correct integration of the DNA sequence. Finally, the modified ES cells are used to generate chimeric animals, which are then bred to produce offspring that carry the genetic modification in their germline.

Overall, gene knock-in techniques provide a powerful tool for studying gene function and developing new therapies for genetic diseases.
