Summary
Prostate cancer risk is linked to the RTK/ERK pathway influenced by natural selection. Specific genes and SNPs, like rs17172432, may be key drivers in prostate cancer (PCa) development.
Area of Science:
- Genetics
- Oncology
- Evolutionary Biology
Background:
- Prostate cancer (PCa) is a significant global health concern with high mortality.
- The RTK/ERK pathway is implicated in PCa development, but its evolutionary mechanisms are not fully understood.
Purpose of the Study:
- To investigate the association between the RTK/ERK pathway, genetic variations, and prostate cancer risk.
- To explore the role of natural selection in the evolution of PCa susceptibility.
Main Methods:
- Combined genotypic and phenotypic data from the ChinaPCa consortium with public databases.
- Performed expression of quantitative trait loci (eQTLs) analysis, natural selection analysis, and gene-based pathway analysis.
Main Results:
- Pathway analysis confirmed a positive correlation between PCa risk and several key genes.
- Four genes (EGFR, ERBB2, PTK2, RAF1) and five SNPs, particularly rs17172432, were identified as potentially pivotal in PCa development under natural selection.
- The RTK/ERK pathway, influenced by natural selection, appears critical in modulating PCa risk.
Conclusions:
- The interplay between the RTK/ERK pathway, natural selection, and specific genetic loci contributes to prostate cancer risk.
- Understanding these combined effects may offer insights into PCa prevention and therapeutic 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.

64.7K
Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

15.6K
Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...

01:22PI3K/mTOR/AKT Signaling Pathway
5.2K
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...

02:38The Ras Gene
5.7K
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.
