Expression of genes involved in the regulation of p16 in psoriatic involved skin

, 2006
It has been suggested that the up-regulation of the tumour suppressor p16 gene and induction of senescence protect the phenotype of psoriatic involved skin from malignant transformation.

A Bi‐Adjuvant Senolytic Nanovaccine Modulating Dendritic Cell Senescence Ameliorates Aging‐Related Metabolic Dysfunction

Advanced Science, EarlyView.
An active biomaterial‐based bi‐adjuvant nanovaccine restores the immunocompetence of aged dendritic cells to overcome senescent cell tolerance. Accompanied by the downregulation of mitotic kinases Aurka/b and attenuation of senescence‐associated PI3K/AKT phosphorylation, the nanovaccine enhances antigen‐presenting capacity and promotes potent cytotoxic

Bone marrow p16^INK4a-deficiency alters hepatic, but not AT HFD-induced gene expression.

, 2013
p16+/+ BMT (chow n = 9; HFD n = 12) or p16−/− BMT (chow n = 8; HFD n = 12) mice were sacrificed after 22 weeks of dietary treatment. Epidydimal AT (A) and liver (B) mRNA were isolated and inflammatory genes were measured by qPCR.

PHGDH‐Mediated Serine Metabolism in Nucleus Pulposus Cells Is a Potential Therapeutic Target for Intervertebral Disc Degeneration

Advanced Science, EarlyView.
When nucleus pulposus cells senesce, PHGDH decreases, reducing serine synthesis and glutathione, impairing antioxidant capacity. The intermediate α‐KG also drops, lowering JMJD3 demethylase activity, increasing H3K27me3 at the Rap1b promoter, and reducing Rap1b expression, whose down‐regulation in turn activates mTORC1 and suppresses autophagy ...

Microenvironment‐Responsive Biomimetic Hydrogels Delivering Cistanche Deserticola‐Derived Nanovesicles for Intervertebral Disc Degeneration

Advanced Science, EarlyView.
An injectable, microenvironment‐responsive hydrogel (HAPOCS@CDNVs) is developed for sustained delivery of Cistanche deserticola‐derived nanovesicles (CDNVs). By scavenging ROS, restoring mitochondrial function, and attenuating SASP, this platform effectively suppresses nucleus pulposus cell senescence and facilitates extracellular matrix reconstruction,

Carcinoma gástrico e gastrite crónica: regulação epigenética por metilação dos genes CDH1 (Caderina-E), CDKN2A (p16INK4A), PTGS2 (COX2) e EGFR.

Acta Médica Portuguesa, 2010
The genetic and epigenetic alterations are being studied as one of the causes of gastric cancer (GC) progression and development. DNA methylation is an epigenetic alteration which leads to suppressor gene silencing and proto-oncogene activation, playing ...

Methylation and mutation analysis of p16 gene in gastric cancer

World Journal of Gastroenterology, 2003
To study methylation, frequencies of homozygous deletion and mutation of p16 gene in gastric carcinoma.The methylation pattern in exon 1 and exon 2 of p16 gene was studied with polymerase chain reaction (PCR), using methylation sensitive restriction endonuclease HpaII and methylation insensitive restriction endonuclease MspI.

Cloning and characterization of murine p16(INK4a) and p15(INK4b) genes

, 1995
Progression through the G1 phase of the cell cycle is regulated in part by the D-type cyclin-dependent kinases, cdk4 and cdk6. Genes encoding two specific inhibitors of these kinases, human p16((INK4a/MTS1)) and p15((INK4b/MTS2)) map to a region of ...

Genetic detection of bladder cancer by microsatellite analysis of p16, RB1 and p53 tumor suppressor genes

, 2001
Purpose: We investigated the incidence of genetic alterations in urine specimens from patients with bladder cancer. Materials and Methods: A total of 28 cytological urine specimens were assessed for microsatellite alternations, and 15 microsatellite ...
