Salvianolic Acid a Disrupts the HSP90α‐AKT‐PERK Ternary Complex to Alleviate Atherosclerosis by Activating Endoplasmic Reticulum Stress of Senescent Vascular Smooth Muscle Cells

Advanced Science, EarlyView.
Salvianolic acid A (SAA) selectively induces senescent vascular smooth muscle cell apoptosis, alleviating atherosclerosis. Mechanistically, SAA targets heat shock protein 90 alpha (HSP90α) to disrupt the protein inase B (AKT)‐PRKR‐Like Endoplasmic Reticulum Kinase (PERK) scaffold, driving ubiquitin‐proteasome‐dependent AKT degradation.

p16(INK4A) positively regulates p21(WAF1) expression by suppressing AUF1-dependent mRNA decay. [PDF]

PLoS ONE, 2013
BACKGROUND: p16(INK4a) and p21(WAF1) are two independent cyclin-dependent kinase inhibitors encoded by the CDKN2A and CDKN1A genes, respectively. p16(INK4a) and p21(WAF1) are similarly involved in various anti-cancer processes, including the regulation ...

Prognostic significance of epigenetic inactivation of p16, p15, MGMT and DAPK genes in follicular lymphoma

, 2013
In this study, methylation-specific polymerase chain reaction was used to investigate the role and potential prognostic significance of the methylation status of p16, p15, MGMT and DAPK genes in 32 specimens of follicular lymphoma (FL).

Tracking CDK1 Dynamics With a Novel Biosensor Mouse and Clinical Cohorts to Predict CDK4/6 Inhibitor Sensitivity in ER+ Breast Cancer

Advanced Science, EarlyView.
Cyclin‐dependent kinase (CDK) 1 activity is a dynamic marker of treatment response in estrogen receptor positive breast cancer. Patient cohorts reveal CDK1 activity increases during progression to invasive disease, where high expression correlates with poor survival. Using a novel Cdk1 biosensor mouse alongside in vitro models, we demonstrate that CDK1

p300/Sp1-Mediated High Expression of p16 Promotes Endothelial Progenitor Cell Senescence Leading to the Occurrence of Chronic Obstructive Pulmonary Disease

Mediators of Inflammation, 2021
Objective. Chronic obstructive pulmonary disease (COPD) is a common chronic disease and develops rapidly into a grave public health problem worldwide. However, what exactly causes the occurrence of COPD remains largely unclear.

Deletions of p15 and/or p16 genes as a poor-prognosis factor in adult T-cell leukemia.

, 1997
PURPOSE To determine the frequency of the deletions of p15/p16 genes in adult T-cell leukemia (ATL) cells and to evaluate their value in the diagnosis of clinical subtypes of ATL patients and the prediction of their clinical outcome.

Restores Aβ Clearance by Overcoming PCSK9–LRP1 Dysregulation and TRIB3‐Mediated Autophagy Blockade in Alzheimer's Disease

Advanced Science, EarlyView.
PCSK9 upregulation in cerebrovascular endothelial cells and microglia destabilizes the Aβ transporter LRP1, while TRIB3‐associated autophagy blockade further limits intracellular Aβ degradation. A RAP‐modified tea‐polyphenol nanoparticle co‐delivers siPCSK9 and siTRIB3 to restore LRP1‐mediated Aβ efflux and autophagy‐dependent degradation, reducing Aβ ...

Inactivation of p16 gene in leukemia.

Chinese medical sciences journal = Chung-kuo i hsueh k'o hsueh tsa chih, 2003
To determine the frequency of p16 gene inactivation in leukemia cells, and to evaluate their value in the prediction of their clinical outcome. Bone marrow or peripheral blood samples from 48 patients with leukemia were examined by multiplex polymerase chain reaction (MPCR) to detect p16 gene homozygous deletion, and restriction enzyme PCR to detect ...

Micro-RNAS Regulate Metabolic Syndrome-induced Senescence in Porcine Adipose Tissue-derived Mesenchymal Stem Cells through the P16/MAPK Pathway

Cell Transplantation, 2018
Mesenchymal stem cells (MSCs) constitute an important repair system, but may be impaired by exposure to cardiovascular risk factors. Consequently, adipose tissue-derived MSCs from pigs with the metabolic syndrome (MetS) show decreased vitality. A growing
