Summary
Extracellular signal-regulated kinase 5 (ERK5) is crucial in normal cell functions and increasingly implicated in cancer development and progression. This review highlights ERK5
Area of Science:
- Molecular Biology
- Cell Signaling
- Oncology
Background:
- Extracellular signal-regulated kinase 5 (ERK5) is a unique MAPK family member with a significant role in normal cell growth, survival, and differentiation.
- ERK5 is increasingly recognized for its involvement in inflammatory disorders and various cancers, influencing tumor initiation and progression.
Purpose of the Study:
- To review the gene expression profile of ERK5 in cancers and its correlation with clinical impact.
- To evaluate the prognostic value of ERK5 and phosphorylated ERK5 (pERK5) expression in tumors.
- To summarize ERK5's role in cancer stem-like cell maintenance and the tumor microenvironment.
Main Methods:
- Literature review of studies investigating ERK5 expression, clinical impact, and prognostic value in cancer.
- Analysis of gene expression profiles and their correlation with cancer outcomes.
- Summary of research on ERK5's role in cancer stemness and the tumor microenvironment.
Main Results:
- ERK5 expression profiles correlate with clinical impact across various cancers.
- ERK5 and pERK5 levels serve as potential prognostic markers in tumors.
- ERK5 is vital for maintaining cancer stem-like phenotypes and influences the tumor microenvironment.
Conclusions:
- ERK5 plays a significant role in cancer initiation, progression, and the tumor microenvironment.
- ERK5 and its isoforms represent potential therapeutic targets for cancer treatment.
- Further research into ERK5's molecular regulation and alternative splicing is warranted for clinical applications.

02:38Mitogens and the Cell Cycle
7.0K
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...

03:03mTOR Signaling and Cancer Progression
3.9K
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
6.4K
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...

01:22PI3K/mTOR/AKT Signaling Pathway
4.1K
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
6.6K
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...

02:34Inhibition of Cdk Activity
5.0K
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
