What does the ERK pathway do?

What does the ERK pathway do?

Role of mitogen signaling in cell cycle progression The ERK pathway plays an important role of integrating external signals from the presence of mitogens such as epidermal growth factor (EGF) into signaling events promoting cell growth and proliferation in many mammalian cell types.

What is the difference between MAPK and ERK?

Studies have shown that the JNK and p38 MAPK pathways are mainly related to stress and apoptosis of cells, while the ERK/MAPK signalling pathway, which is the most thoroughly studied MAPK signalling pathway, is closely related to cell proliferation and differentiation and plays a pivotal role in the cell signal …

What is the ERK 1/2 pathway?

The extracellular signal-regulated kinase 1/2 (ERK1/2) cascade is a central signaling pathway that regulates a wide variety of stimulated cellular processes, including mainly proliferation, differentiation, and survival, but apoptosis and stress response as well.

What is ERK in cancer?

A study has demonstrated that activated ERK protects cancer cells from the cytotoxic effects of radiation (51). ERKs promote cell survival in various ways, including via the inhibition of apoptosis, the induction of DNA damage repair and the arrest of the cell cycle.

What is ERK Signalling?

ERK signalling in cell proliferation. In proliferating cells, RAS-induced ERK signalling primarily controls the G1/S-phase transition of the cell cycle. Notably, deletion of the three Ras genes or loss of Erk1 and Erk2 in mouse embryonic fibroblasts (MEFs) induces a cell cycle arrest in G1 phase (refs43,44).

Why is MAPK pathway important?

The mitogen-activated protein kinase (MAPK) pathway plays a role in the regulation of gene expression, cellular growth, and survival. Abnormal MAPK signaling may lead to increased or uncontrolled cell proliferation and resistance to apoptosis. Research into the MAPK pathway has shown it to be important in some cancers.

How does ERK get phosphorylated?

Upon stimulation, ERK is activated by phosphorylation of its regulatory Tyr and Thr [45] that also induce a conformational change that releases it from the anchoring proteins [46].

What is the role of extracellular signal-regulated kinase (ERK) signalling in cancer?

It has been reported that extracellular signal-regulated kinase (ERK) signalling is a crucial pathway for the regulation of cell proliferation, differentiation, survival and cell motility in both normal and cancer cells [ 46 – 48 ], and the activation of ERK1/2 stimulates the expression of VEGFa in breast cancer cells [ 49 ].

Is the BRAF/MEK pathway associated with breast cancer in ER-dependent mode?

BRAF/MEK Pathway is Associated With Breast Cancer in ER-dependent Mode and Improves ER Status-based Cancer Recurrence Prediction Aberrant BRAF/MEK signaling was found in nearly 50% of human malignancies and proved to play a critical role in the tumorigenesis of multiple cancers.

Does ACE2 inhibit breast cancer angiogenesis through vegfa/vegfr2/erk pathway?

Our findings suggest that ACE2, as a potential resister to breast cancer, might inhibit breast cancer angiogenesis through the VEGFa/VEGFR2/ERK pathway. Retrospectively registered. The online version of this article (10.1186/s13046-019-1156-5) contains supplementary material, which is available to authorized users.

Does ERK signaling play a role in ACE2 downregulation of VEGFA?

This revealed that ERK signalling played a role in the process through which ACE2 downregulated VEGFa expression in breast cancer cells. It has been reported that secreted VEGFa usually combines with VEGFR2 on the endothelial cell membrane to promote angiogenesis [ 7 ].
