Summary
Mitogen-activated protein kinase (MAPK) signaling regulates cell functions but can drive cancer when aberrant. This review overviews MAPK mechanisms in tumor generation and discusses targeted cancer therapies.
Area of Science:
- Cellular signaling pathways
- Molecular biology
- Cancer research
Background:
- Mitogen-activated protein kinase (MAPK) pathways are crucial for cellular responses to stimuli.
- MAPK signaling regulates fundamental biological processes including proliferation, differentiation, and inflammation.
- Aberrant MAPK activation is implicated in various human cancers.
Purpose of the Study:
- To review recent studies on MAPK signaling mechanisms.
- To elucidate how MAPK pathways contribute to tumorigenesis.
- To discuss current and emerging therapeutic strategies targeting the MAPK network in cancer.
Main Methods:
- Extensive analysis of published scientific literature.
- Review of mechanistic studies on MAPK signaling.
- Compilation of data on MAPK pathway alterations in cancer.
Main Results:
- MAPK pathways, particularly the RAS-MAPK pathway, are frequently altered in cancer due to mutations or receptor activation.
- MAPK signaling components like p38, JNK, and ERK are recognized therapeutic targets.
- The role of MAPK signaling in apoptotic cell death remains controversial and requires further investigation.
Conclusions:
- Understanding MAPK pathway dysregulation is key to developing effective cancer treatments.
- Targeting specific MAPK components offers promising therapeutic avenues for various malignancies.
- Further research is needed to clarify MAPK's role in apoptosis and refine treatment strategies.

03:03mTOR Signaling and Cancer Progression
3.6K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

01:07MAPK Signaling Cascades
7.2K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

5.1K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

01:19Interactions Between Signaling Pathways
4.6K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

02:38Mitogens and the Cell Cycle
6.3K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
