Summary
The PRMT5-E2F1 pathway regulates cell cycle control and cancer progression. Targeting this axis, involving arginine methylation of E2F1, offers a potential therapeutic strategy for cancer.
Area of Science:
- Molecular Biology
- Cancer Biology
- Cell Cycle Regulation
Background:
- The pRb-E2F pathway is crucial for cell cycle control, and its dysregulation is a hallmark of cancer.
- Arginine methylation by PRMT5 significantly influences E2F1 activity, a key target of pRb.
Purpose of the Study:
- To investigate the functional role of the PRMT5-E2F1 axis in cancer cell biology.
- To identify genes regulated by PRMT5 and E2F1 and their impact on malignant phenotypes.
Main Methods:
- Genome-wide expression analysis to identify PRMT5 and E2F1 target genes.
- Functional assays assessing cancer cell viability, migration, invasion, and adherence.
Main Results:
- The PRMT5-E2F1 axis influences cancer cell viability, migration, invasion, and adherence.
- A distinct set of genes, critical for cell migration and invasion, are under PRMT5-dependent control.
- Elevated PRMT5 and E2F1 expression in human tumors correlates with poor prognosis.
Conclusions:
- A causal relationship exists between PRMT5 and E2F1 in promoting the malignant phenotype.
- The PRMT5-E2F1 pathway represents a significant therapeutic target for cancer intervention.

mTOR Signaling and Cancer Progression
4.5K
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.

Mitogens and the Cell Cycle
7.5K
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...

Abnormal Proliferation
5.0K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

MAPK Signaling Cascades
7.6K
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...

PI3K/mTOR/AKT Signaling Pathway
5.0K
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...

The Ras Gene
6.9K
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
