p16 - Wikipedia
Webp16 (also known as p16 INK4a, cyclin-dependent kinase inhibitor 2A, CDKN2A, multiple tumor suppressor 1 and numerous other synonyms), is a protein that slows cell division by slowing the progression of the cell cycle from the G1 phase to the S phase, thereby acting as a tumor suppressor.

WebJan 25, 2024 · Definition / general. Tumor suppressor protein encoded by CDKN2A gene (9p21.3) Prevents progression into S phase of cell cycle. Inhibits cyclin D dependent protein kinases (CDK4 and CDK6) therefore maintaining Rb in its hypophosphorylated state which prevents its dissociation from E2F transcription factor. Protein expression often …
Oral Cavity and Oropharyngeal Cancer Stages
WebOropharyngeal cancers that contain HPV DNA (called p16-positive) tend to have a better outlook than those without HPV (p16-negative). Because p16-positive cancers have a better prognosis than p16-negative oropharyngeal cancers, separate staging systems are used. Both systems are described below.

WebNov 14, 2023 · p16 is a protein made by normal cells throughout the body. It can also be made by abnormal cells including some types of cancers. It is a type of protein called a tumour suppressor. This means that the normal role of this protein is to stop the cell from changing into a cancer cell.
How Does p16 Play a Major Role in Cancer Research?
Webp16 is a tumor suppressor protein that plays an important role in cell cycle regulation. It is now being used as a biomarker for a number of cancers. Since its discovery, p16 has become highly significant in cancer research.
