Cigarette Smoke‐Induced Alveolar Macrophage Senescence via GEM/SIRT3‐Mediated Mitochondrial Dysfunction

Advanced Science, EarlyView.
Cigarette smoke accelerates the aging of immune cells in the lung. By combining human single‐cell sequencing, cell culture, and mouse models, the authors show that the protein GEM drives mitochondrial damage and senescence in alveolar macrophages by suppressing SIRT3.

Mutations of the p16 gene in gliomas.

Oncogene, 1996
In the present study we investigated the frequency of p16 gene exon 2 mutations in 35 malignant gliomas, using either direct sequencing of the PCR products or cloning into the pCRII vector and sequencing of the cloned PCR products. No mutations were detected during direct sequencing of the PCR products.

ABCB5 and the regulation of p16INK4a by non-coding RNA [PDF]

, 2014
p16INK4a (p16) traps the cell at the restriction point of the cell cycle by binding to cyclin-dependent kinase 4/6 thus preventing the phosphorylation of the retinoblastoma protein (pRB).

Comethylation of p16 and MGMT genes in colorectal carcinoma: Correlation with clinicopathological features and prognostic value

, 2007
AIM: To investigate the significance of p16 and O-6- methylguanine-DNA methyltransferase (MGMT) genes promoter hypermethylation and K-ras mutations on colorectal tumorigenesis and progression.

FUCA2 Sustains AKT Signaling and Suppresses Senescence by Antagonizing FUT3‐Mediated ErbB3 Fucosylation in Lung Adenocarcinoma

Advanced Science, EarlyView.
ABSTRACT While targeted therapies have improved outcomes in lung adenocarcinoma (LUAD), many patients still lack targetable mutations. Here, we identified alpha‐L‐fucosidase 2 (FUCA2) as a crucial driver of LUAD by preventing cellular senescence. Mechanistically, through the restriction of fucosyltransferase 3 (FUT3)‐mediated α‐1,3‐fucosylation of ...

p16 gene homozygous deletions in acute lymphoblastic leukemia [PDF]

Blood, 1995
The p16 protein is a cyclin inhibitor encoded by a gene located in 9p21, which may have antioncogenic properties, and is inactivated by homozygous p16 gene deletion or, less often, point mutation in several types of solid tumors often associated to cytogenetic evidence of 9p21 deletion.

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.

Optimized Ex Vivo Human Liver Slice Culture Maintains Extended Viability and Function for Hepatotoxicity Testing

Advanced Science, EarlyView.
An optimized ex vivo human liver slice culture system preserves tissue architecture, hepatocyte function, and immune‐stromal complexity for at least five days. By refining slice thickness, oxygenation, air‐liquid interface, and extracellular matrix support, the platform enables human‐relevant hepatotoxicity testing and mechanistic studies, offering a ...

Bioadhesive Hydrogel With Polyphenol‐Armored Nanogene Rejuvenates Chondrocyte Senescence for Aged Osteoarthritis Therapy

Advanced Science, EarlyView.
An adhesive hydrogel depot with polyphenol‐armored nanogenes is developed for treating aged osteoarthritis. This system maintains miR‐140 bioactivity, prolongs its intra‐articular retention, and enhances transfection into chondrocytes, leading to the downregulation of senescence‐associated pathways.

A senolytic immunotoxin eliminates p16INK4a-positive T cells and ameliorates age-associated phenotypes of CD4+ T cells in a surface marker knock-in mouse

Experimental Gerontology, 2023
Senescent cells were recently shown to play a role in aging-related malfunctions and pathologies. This consensus has been facilitated by evidence from senolytic model mice capable of eliminating senescent cells in tissues using well-characterized ...
