Loss of p16INK4A stimulates aberrant mitochondrial biogenesis through a CDK4/Rb-independent pathway
The tumor suppressor p16INK4A (p16) inhibits cell cycle progression through the CDK4/Rb pathway. We have previously shown that p16 regulates cellular oxidative stress, independent of its role in cell cycle control. We investigated whether loss of p16 had a direct impact on the mitochondria. We found that p16-null primary mouse fibroblasts (PMFs) displayed increased mitochondrial mass and expres...
متن کاملPetri net based modelling and simulation of p16-Cdk4/6-Rb pathway
Tumor suppressor gene p16 is of utmost interest in investigation of signal transduction pathways due to its gatekeeper role at the G1/S checkpoint of the cell cycle. Defects in p16 result in uncontrolled cell division which leads to progression of malignancy in an organism. In the present research we focus on p16-Cdk4/6-Rb pathway which is a cornerstone of G1 phase of the cell cycle. We impleme...
متن کاملNovel insights into the INK4-CDK4/6-Rb pathway: counter action of gankyrin against INK4 proteins regulates the CDK4-mediated phosphorylation of Rb.
The newly discovered oncogenic protein gankyrin, which contains six ankyrin repeats, has been reported to be involved in the phosphorylation and degradation of the retinoblastoma gene product, Rb. Using in vitro systems, we have identified a peptide fragment of gankyrin, 176LHLACDEERN185, which is responsible for binding of gankyrin to Rb. We further demonstrated a different mechanism for ganky...
متن کاملDuhuo Jisheng Decoction‑containing serum promotes proliferation of interleukin‑1β‑induced chondrocytes through the p16‑cyclin D1/CDK4‑Rb pathway.
Duhuo Jisheng Decoction (DHJSD) is a traditional Chinese herbal medicine that has multiple uses, including as a treatment for osteoarthritis (OA). However, the molecular mechanisms underlying the therapeutic effects of DHJSD on OA remain unknown. In the present study, a serum pharmacological method was applied to investigate the effects of DHJSD on the proliferation of chondrocytes treated with...
متن کاملRB-E2F1 Pathway Regulates Autophagy
ownloade ophagy is a protective mechanism that renders cells viable in stressful conditions. Emerging evidence ts that this cellular process is also a tumor suppressor pathway. Previous studies showed that cyclindent kinase inhibitors (CDKI) induce autophagy. Whether retinoblastoma protein (RB), a key tumor ssor and downstream target of CDKIs, induces autophagy is not clear. Here, we show that ...
