Cell adhesion regulates the interaction between the docking protein p130(Cas) and the 14-3-3 proteins. (1/356)

Integrin ligand binding induces a signaling complex formation via the direct association of the docking protein p130(Cas) (Cas) with diverse molecules. We report here that the 14-3-3zeta protein interacts with Cas in the yeast two-hybrid assay. We also found that the two proteins associate in mammalian cells and that this interaction takes place in a phosphoserine-dependent manner, because treatment of Cas with a serine phosphatase greatly reduced its ability to bind 14-3-3zeta. Furthermore, the Cas-14-3-3zeta interaction was found to be regulated by integrin-mediated cell adhesion. Thus, when cells are detached from the extracellular matrix, the binding of Cas to 14-3-3zeta is greatly diminished, whereas replating the cells onto fibronectin rapidly induces the association. Consistent with these results, we found that the subcellular localization of Cas and 14-3-3 is also regulated by integrin ligand binding and that the two proteins display a significant co-localization during cell attachment to the extracellular matrix. In conclusion, our results demonstrate that 14-3-3 proteins participate in integrin-activated signaling pathways through their interaction with Cas, which, in turn, may contribute to important biological responses regulated by cell adhesion to the extracellular matrix.  (+info)

Alternatively spliced EDA segment regulates fibronectin-dependent cell cycle progression and mitogenic signal transduction. (2/356)

Fibronectin (FN) is comprised of multiple isoforms arising from alternative splicing of a single gene transcript. One of the alternatively spliced segments, EDA, is expressed prominently in embryonic development, malignant transformation, and wound healing. We showed previously that EDA+ FN was more potent than EDA- FN in promoting cell spreading and cell migration because of its enhanced binding affinity to integrin alpha5beta1 (Manabe, R., Oh-e, N., Maeda, T., Fukuda, T., and Sekiguchi, K. (1997) J. Cell Biol. 139, 295-307). In this study, we compared the cell cycle progression and its associated signal transduction events induced by FN isoforms with or without the EDA segment to examine whether the EDA segment modulates the cell proliferative potential of FN. We found that EDA+ FN was more potent than EDA- FN in inducing G1-S phase transition. Inclusion of the EDA segment potentiated the ability of FN to induce expression of cyclin D1, hyperphosphorylation of pRb, and activation of mitogen-activated protein kinase extracellular signal regulated kinase 2 (ERK2). EDA+ FN was also more potent than EDA- FN in promoting FN-mediated tyrosine phosphorylation of p130(Cas), but not focal adhesion kinase, which occurred in parallel with the activation of ERK2, suggesting that p130(Cas) may be involved in activation of ERK2. These results indicated that alternative splicing at the EDA region is a novel mechanism that promotes FN-induced cell cycle progression through up-regulation of integrin-mediated mitogenic signal transduction.  (+info)

Agonist-stimulated cytoskeletal reorganization and signal transduction at focal adhesions in vascular smooth muscle cells require c-Src. (3/356)

Thrombin and angiotensin II (angII) have trophic properties as mediators of vascular remodeling. Focal adhesions and actin cytoskeleton are involved in cell growth, shape, and movement and may be important in vascular remodeling. To characterize mechanisms by which thrombin and angII modulate vessel structure, we studied the effects of these G protein-coupled receptor ligands on focal adhesions in vascular smooth muscle cells (VSMCs). Both thrombin and angII stimulated bundling of actin filaments to form stress fibers, assembly of focal adhesions, and protein tyrosine phosphorylation at focal adhesions, such as p130Cas, paxillin, and tensin. To test whether c-Src plays a critical role in focal adhesion rearrangement, we analyzed cells with altered c-Src activity by retroviral transduction of wild-type (WT) and kinase-inactive (KI) c-Src into rat VSMCs, and by use of VSMCs from WT (src+/+) and Src-deficient (src-/-) mice. Tyrosine phosphorylation of Cas, paxillin, and tensin were markedly decreased in VSMCs expressing KI-Src and in src-/- VSMCs. Expression of KI-Src did not inhibit stress fiber formation by thrombin. Surprisingly, actin bundling was markedly decreased in VSMCs from src-/- mice both basally and after thrombin stimulation, compared with src+/+ mice. We also studied the effect of KI-Src and WT-Src on VSMC spreading. Expression of KI-Src reduced the rate of VSMC spreading on collagen, whereas WT-Src enhanced cell spreading. In conclusion, c-Src plays a critical role in agonist-stimulated cytoskeletal reorganization and signal transduction at focal adhesions in VSMCs. c-Src kinase activity is required for the cytoskeletal turnover that occurs in cell spreading, whereas c-Src appears to regulate actin bundling via a kinase-independent mechanism.  (+info)

NSP1 defines a novel family of adaptor proteins linking integrin and tyrosine kinase receptors to the c-Jun N-terminal kinase/stress-activated protein kinase signaling pathway. (4/356)

As part of a program to further understand the mechanism by which extracellular signals are coordinated and cell-specific outcomes are generated, we have cloned a novel class of related adaptor molecules (NSP1, NSP2, and NSP3) and have characterized in more detail one of the members, NSP1. NSP1 has an Shc-related SH2 domain and a putative proline/serine-rich SH3 interaction domain. Treatment of cells with epidermal growth factor or insulin leads to NSP1 phosphorylation and increased association with a hypophosphorylated adaptor protein, p130(Cas). In contrast, cell contact with fibronectin results in Cas phosphorylation and a transient dissociation of NSP1 from p130(Cas). Increased expression of NSP1 in 293 cells induces activation of JNK1, but not of ERK2. Consistent with this observation, NSP1 increases the activity of an AP-1-containing promoter. Thus, we have described a novel family of adaptor proteins, one of which may be involved in the process by which receptor tyrosine kinase and integrin receptors control the c-Jun N-terminal kinase/stress-activated protein kinase pathway.  (+info)

Rho-dependent and -independent tyrosine phosphorylation of focal adhesion kinase, paxillin and p130Cas mediated by Ret kinase. (5/356)

Glial cell line-derived neurotrophic factor (GDNF) signals through a unique receptor system that includes Ret receptor tyrosine kinase and a glycosyl-phosphatidylinositol-linked cell surface protein. In the present study, we have identified several proteins in neuroblastoma cells that are phosphorylated on tyrosine in response to GDNF. The phosphorylated proteins include focal adhesion kinase (FAK), paxillin and Crk-associated substrate, p130Cas, all of which are known to be associated with focal adhesions. Of these, paxillin and p130Cas interacted with Crk proteins in GDNF-treated neuroblastoma cells. GDNF also induced reorganization of the actin cytoskelton. Tyrosine phosphorylation of FAK, paxillin and p130Cas was inhibited by cytochalasin D or two specific inhibitors of phosphatidylinositol-3' kinase (PI-3' kinase), wortmannin and LY294002, indicating that their tyrosine phosphorylation depends on the formation of actin stress fiber and activation of PI-3' kinase. In addition, phosphorylation of FAK but not of paxillin and p130Cas was markedly impaired by the Clostridium botulinum C3 exoenzyme that specifically ADP-ribosylates and inactivates Rho. These results suggested the presence of Rho-dependent and -independent signaling pathways downstream of PI-3' kinase that mediate tyrosine phosphorylation of FAK, paxillin and p130Cas through Ret kinase.  (+info)

CMS: an adapter molecule involved in cytoskeletal rearrangements. (6/356)

Cas ligand with multiple Src homology (SH) 3 domains (CMS) is an ubiquitously expressed signal transduction molecule that interacts with the focal adhesion protein p130(Cas). CMS contains three SH3 in its NH2 terminus and proline-rich sequences in its center region. The latter sequences mediate the binding to the SH3 domains of p130(Cas), Src-family kinases, p85 subunit of phosphatidylinositol 3-kinase, and Grb2. The COOH-terminal region contains putative actin binding sites and a coiled-coil domain that mediates homodimerization of CMS. CMS is a cytoplasmic protein that colocalizes with F-actin and p130(Cas) to membrane ruffles and leading edges of cells. Ectopic expression of CMS in COS-7 cells resulted in alteration in arrangement of the actin cytoskeleton. We observed a diffuse distribution of actin in small dots and less actin fiber formation. Altogether, these features suggest that CMS functions as a scaffolding molecule with a specialized role in regulation of the actin cytoskeleton.  (+info)

Induced focal adhesion kinase (FAK) expression in FAK-null cells enhances cell spreading and migration requiring both auto- and activation loop phosphorylation sites and inhibits adhesion-dependent tyrosine phosphorylation of Pyk2. (7/356)

Focal adhesion kinase (FAK) is a nonreceptor protein tyrosine kinase involved in integrin-mediated control of cell behavior. Following cell adhesion to components of the extracellular matrix, FAK becomes phosphorylated at multiple sites, including tyrosines 397, 576, and 577. Tyr-397 is an autophosphorylation site that promotes interaction with c-Src or Fyn. Tyr-576 and Tyr-577 lie in the putative activation loop of the kinase domain, and FAK catalytic activity may be elevated through phosphorylation of these residues by associated Src family kinase. Recent studies have implicated FAK as a positive regulator of cell spreading and migration. To further study the mechanism of adhesion-induced FAK activation and the possible role and signaling requirements for FAK in cell spreading and migration, we utilized the tetracycline repression system to achieve inducible expression of either wild-type FAK or phosphorylation site mutants in fibroblasts derived from FAK-null mouse embryos. Using these Tet-FAK cells, we demonstrated that both the FAK autophosphorylation and activation loop sites are critical for maximum adhesion-induced FAK activation and FAK-enhanced cell spreading and migration responses. Negative effects on cell spreading and migration, as well as decreased phosphorylation of the substrate p130(Cas), were observed upon induced expression of the FAK autophosphorylation site mutant. These negative effects appear to result from an inhibition of integrin-mediated signaling by the FAK-related kinase Pyk2/CAKbeta/RAFTK/CadTK.  (+info)

Integrin-mediated activation of focal adhesion kinase is required for signaling to Jun NH2-terminal kinase and progression through the G1 phase of the cell cycle. (8/356)

The extracellular matrix exerts a stringent control on the proliferation of normal cells, suggesting the existence of a mitogenic signaling pathway activated by integrins, but not significantly by growth factor receptors. Herein, we provide evidence that integrins cause a significant and protracted activation of Jun NH2-terminal kinase (JNK), while several growth factors cause more modest or no activation of this enzyme. Integrin-mediated stimulation of JNK required the association of focal adhesion kinase (FAK) with a Src kinase and p130(CAS), the phosphorylation of p130(CAS), and subsequently, the recruitment of Crk. Ras and PI-3K were not required. FAK-JNK signaling was necessary for proper progression through the G1 phase of the cell cycle. These findings establish a role for FAK in both the activation of JNK and the control of the cell cycle, and identify a physiological stimulus for JNK signaling that is consistent with the role of Jun in both proliferation and transformation.  (+info)

Explanation: Neoplastic cell transformation is a complex process that involves multiple steps and can occur as a result of genetic mutations, environmental factors, or a combination of both. The process typically begins with a series of subtle changes in the DNA of individual cells, which can lead to the loss of normal cellular functions and the acquisition of abnormal growth and reproduction patterns.

Over time, these transformed cells can accumulate further mutations that allow them to survive and proliferate despite adverse conditions. As the transformed cells continue to divide and grow, they can eventually form a tumor, which is a mass of abnormal cells that can invade and damage surrounding tissues.

In some cases, cancer cells can also break away from the primary tumor and travel through the bloodstream or lymphatic system to other parts of the body, where they can establish new tumors. This process, known as metastasis, is a major cause of death in many types of cancer.

It's worth noting that not all transformed cells will become cancerous. Some forms of cellular transformation, such as those that occur during embryonic development or tissue regeneration, are normal and necessary for the proper functioning of the body. However, when these transformations occur in adult tissues, they can be a sign of cancer.

Examples of mammary neoplasms in animals include:

* Mammary adenocarcinoma: A type of tumor that develops in the mammary gland of animals and is characterized by the growth of abnormal cells that produce milk.
* Mammary fibroadenoma: A benign tumor that develops in the mammary gland of animals and is characterized by the growth of fibrous and glandular tissue.
* Inflammatory mammary carcinoma: A type of tumor that develops in the mammary gland of animals and is characterized by the presence of inflammatory cells and abnormal cells.

These tumors can be caused by a variety of factors, including genetic mutations, hormonal imbalances, and exposure to certain environmental agents. They can also be induced experimentally using chemical carcinogens or viruses.

The study of mammary neoplasms in animals is important for understanding the molecular mechanisms underlying breast cancer development and progression, as well as for identifying potential therapeutic targets and developing new treatments.

Starvation is a condition where an individual's body does not receive enough nutrients to maintain proper bodily functions and growth. It can be caused by a lack of access to food, poverty, poor nutrition, or other factors that prevent the intake of sufficient calories and essential nutrients. Starvation can lead to severe health consequences, including weight loss, weakness, fatigue, and even death.

Types of Starvation:

There are several types of starvation, each with different causes and effects. These include:

1. Acute starvation: This occurs when an individual suddenly stops eating or has a limited access to food for a short period of time.
2. Chronic starvation: This occurs when an individual consistently does not consume enough calories and nutrients over a longer period of time, leading to gradual weight loss and other health problems.
3. Malnutrition starvation: This occurs when an individual's diet is deficient in essential nutrients, leading to malnutrition and other health problems.
4. Marasmus: This is a severe form of starvation that occurs in children, characterized by extreme weight loss, weakness, and wasting of muscles and organs.
5. Kwashiorkor: This is a form of malnutrition caused by a diet lacking in protein, leading to edema, diarrhea, and other health problems.

Effects of Starvation on the Body:

Starvation can have severe effects on the body, including:

1. Weight loss: Starvation causes weight loss, which can lead to a decrease in muscle mass and a loss of essential nutrients.
2. Fatigue: Starvation can cause fatigue, weakness, and a lack of energy, making it difficult to perform daily activities.
3. Weakened immune system: Starvation can weaken the immune system, making an individual more susceptible to illnesses and infections.
4. Nutrient deficiencies: Starvation can lead to a deficiency of essential nutrients, including vitamins and minerals, which can cause a range of health problems.
5. Increased risk of disease: Starvation can increase the risk of diseases such as tuberculosis, pellagra, and other infections.
6. Mental health issues: Starvation can lead to mental health issues such as depression, anxiety, and irritability.
7. Reproductive problems: Starvation can cause reproductive problems, including infertility and miscarriage.
8. Hair loss: Starvation can cause hair loss, which can be a sign of malnutrition.
9. Skin problems: Starvation can cause skin problems, such as dryness, irritation, and infections.
10. Increased risk of death: Starvation can lead to increased risk of death, especially in children and the elderly.

It is important to note that these effects can be reversed with proper nutrition and care. If you or someone you know is experiencing starvation, it is essential to seek medical attention immediately.

1) They share similarities with humans: Many animal species share similar biological and physiological characteristics with humans, making them useful for studying human diseases. For example, mice and rats are often used to study diseases such as diabetes, heart disease, and cancer because they have similar metabolic and cardiovascular systems to humans.

2) They can be genetically manipulated: Animal disease models can be genetically engineered to develop specific diseases or to model human genetic disorders. This allows researchers to study the progression of the disease and test potential treatments in a controlled environment.

3) They can be used to test drugs and therapies: Before new drugs or therapies are tested in humans, they are often first tested in animal models of disease. This allows researchers to assess the safety and efficacy of the treatment before moving on to human clinical trials.

4) They can provide insights into disease mechanisms: Studying disease models in animals can provide valuable insights into the underlying mechanisms of a particular disease. This information can then be used to develop new treatments or improve existing ones.

5) Reduces the need for human testing: Using animal disease models reduces the need for human testing, which can be time-consuming, expensive, and ethically challenging. However, it is important to note that animal models are not perfect substitutes for human subjects, and results obtained from animal studies may not always translate to humans.

6) They can be used to study infectious diseases: Animal disease models can be used to study infectious diseases such as HIV, TB, and malaria. These models allow researchers to understand how the disease is transmitted, how it progresses, and how it responds to treatment.

7) They can be used to study complex diseases: Animal disease models can be used to study complex diseases such as cancer, diabetes, and heart disease. These models allow researchers to understand the underlying mechanisms of the disease and test potential treatments.

8) They are cost-effective: Animal disease models are often less expensive than human clinical trials, making them a cost-effective way to conduct research.

9) They can be used to study drug delivery: Animal disease models can be used to study drug delivery and pharmacokinetics, which is important for developing new drugs and drug delivery systems.

10) They can be used to study aging: Animal disease models can be used to study the aging process and age-related diseases such as Alzheimer's and Parkinson's. This allows researchers to understand how aging contributes to disease and develop potential treatments.

There are different types of Breast Neoplasms such as:

1. Fibroadenomas: These are benign tumors that are made up of glandular and fibrous tissues. They are usually small and round, with a smooth surface, and can be moved easily under the skin.

2. Cysts: These are fluid-filled sacs that can develop in both breast tissue and milk ducts. They are usually benign and can disappear on their own or be drained surgically.

3. Ductal Carcinoma In Situ (DCIS): This is a precancerous condition where abnormal cells grow inside the milk ducts. If left untreated, it can progress to invasive breast cancer.

4. Invasive Ductal Carcinoma (IDC): This is the most common type of breast cancer and starts in the milk ducts but grows out of them and invades surrounding tissue.

5. Invasive Lobular Carcinoma (ILC): It originates in the milk-producing glands (lobules) and grows out of them, invading nearby tissue.

Breast Neoplasms can cause various symptoms such as a lump or thickening in the breast or underarm area, skin changes like redness or dimpling, change in size or shape of one or both breasts, discharge from the nipple, and changes in the texture or color of the skin.

Treatment options for Breast Neoplasms may include surgery such as lumpectomy, mastectomy, or breast-conserving surgery, radiation therapy which uses high-energy beams to kill cancer cells, chemotherapy using drugs to kill cancer cells, targeted therapy which uses drugs or other substances to identify and attack cancer cells while minimizing harm to normal cells, hormone therapy, immunotherapy, and clinical trials.

It is important to note that not all Breast Neoplasms are cancerous; some are benign (non-cancerous) tumors that do not spread or grow.
