Summary
Oncogene-induced senescence, a cell cycle arrest triggered by oncogenes, acts as a tumor suppressor. This study details a method to induce this senescence in human fibroblasts using oncogenic RAS.
Area of Science:
- Cellular biology
- Cancer research
- Molecular oncology
Background:
- Cellular senescence is a permanent cell cycle arrest that prevents cancer.
- Oncogenes promote cell proliferation and survival, driving cancer progression.
- Oncogene-induced senescence (OIS) is a tumor suppressive mechanism activated by oncogenes.
Purpose of the Study:
- To describe a protocol for inducing OIS in primary human fibroblasts.
- To provide a generalizable method for studying senescence induction by various oncogenes.
Main Methods:
- Induction of oncogenic RAS in primary human fibroblasts.
- Observation and analysis of senescence markers.
Main Results:
- Successful induction of cellular senescence via oncogenic RAS.
- Demonstration of a reliable protocol for OIS induction.
Conclusions:
- Oncogenic RAS effectively induces cellular senescence in human fibroblasts.
- The described protocol is broadly applicable for studying OIS with different oncogenes.

02:38The Ras Gene
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.

02:15Replicative Cell Senescence
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds the telomeric...

01:07MAPK Signaling Cascades
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...
03:03mTOR Signaling and Cancer Progression
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.
