The Senescence Marker p16Ink4a—A Player of Liver Endothelial Cells Physiology

Biology and Life Sciences Forum, 2023
P16INK4A is a tumor suppressor and cell cycle regulator that has been linked to aging and senescence. In development, a potential role of p21 and of p19ARF has been postulated, but little is known about p16. Our previous results revealed a highly dynamic

Digital quantification of p16-positive foci in fibrotic interstitial lung disease is associated with a phenotype of idiopathic pulmonary fibrosis with reduced survival

Respiratory Research, 2022
Background Idiopathic pulmonary fibrosis (IPF) is associated with increased expression of cyclin-dependent kinase inhibitors such as p16 and p21, and subsequent induction of cell cycle arrest, cellular senescence, and pro-fibrotic gene expression.

Aberrant Promoter Methylation of p16 and MGMT Genes in Lung Tumors from Smoking and Never-Smoking Lung Cancer Patients

Neoplasia: An International Journal for Oncology Research, 2006
Aberrant methylation in gene promoter regions leads to transcriptional inactivation of cancer-related genes and plays an integral role in tumorigenesis.

Promoter hypermethylation of p16 and APC in gastrointestinal cancer patients

The Turkish Journal of Gastroenterology, 2014
Background/Aims: Cancer is a consequence of the disruption of cellular regulation. Epigenetic is one of the reasons of this disruption. Epigenetic factors play a role in the carcinogenesis by affecting proto-oncogenes and tumor suppressor genes and it is

Comparison of clinicopathological and genomic profiles in anal squamous cell carcinoma between Japanese and Caucasian cohorts

Scientific Reports, 2023
Anal squamous cell carcinoma (ASCC) is a rare tumor of the gastrointestinal tract. We aimed to compare the genetic backgrounds and their effect on clinical outcomes between Japanese and Caucasian patients with ASCC. Forty-one patients diagnosed with ASCC

p16^INK4a hypermethylation and p53, p16 and MDM2 protein expression in Esophageal Squamous Cell Carcinoma

BMC Cancer, 2010
Background Tumor suppressor genes p53 and p16INK4a and the proto-oncogene MDM2 are considered to be essential G1 cell cycle regulatory genes whose loss of function is associated with ESCC carcinogenesis.

Epigenetic Changes in Tumor Suppressor Genes, P15, P16, APC-3 and E-cadherin in Body Fluid

Kaohsiung Journal of Medical Sciences, 2007
The inactivation of tumor suppressor genes by promoter methylation plays an important role in the development of cancers; it can also be used as a marker to distinguish cancerous cells from non-cancer cells.

Correlation between HPV PCNA, p16, and p21 Expression in Lung Cancer Patients

Cellular Microbiology, 2022
Purpose. Evaluate if human papillomavirus (HPV) infection in lung cancer patients might be helping cancer development by altering p16, p21, and PCNA, key human genes involved in cell proliferation and tumor development. Methods.

Methylation signature of lymph node metastases in breast cancer patients

BMC Cancer, 2012
Background Invasion and metastasis are two important hallmarks of malignant tumors caused by complex genetic and epigenetic alterations. The present study investigated the contribution of aberrant methylation profiles of cancer related genes, APC, BIN1 ...

Digital Spatial Profiling identifies distinct patterns of immuno-oncology-related gene expression within oropharyngeal tumours in relation to HPV and p16 status

Frontiers in Oncology
BackgroundThe incidence of oropharyngeal cancer (OPC) is increasing, due mainly to a rise in Human Papilloma Virus (HPV)-mediated disease. HPV-mediated OPC has significantly better prognosis compared with HPV-negative OPC, stimulating interest in ...
