A database of 146 human CDKN2A gene mutations in cancer was created to standardize information. This resource aids understanding of p16INK4a's role in tumorigenesis.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • The cell cycle is regulated by various factors, including proteins that inhibit cyclin-dependent kinases.
  • The CDKN2A gene (p16INK4A/MTS1) is crucial in cell cycle regulation and is frequently altered in cancers.
  • Inactivation of CDKN2A at the 9p21 locus is linked to familial melanoma, highlighting its significance in cancer development.

Purpose of the Study:

  • To create a standardized database of human CDKN2A gene mutations found in various cancers.
  • To compile comprehensive information on 146 point mutations, including cancer type, cell origin, mutation details, and amino acid changes.
  • To summarize current research on the biochemical and biological functions of p16INK4a, aiding the understanding of its role in tumorigenesis.

Main Methods:

  • Database creation and curation.
  • Systematic collection of data on CDKN2A point mutations from scientific literature.
  • Literature review and summarization of studies on p16INK4a protein function.

Main Results:

  • A database containing 146 human CDKN2A point mutations has been established.
  • Each entry includes detailed information such as cancer type, cell origin, specific mutation, and amino acid alterations.
  • The database serves as a centralized resource for researchers studying CDKN2A in cancer.

Conclusions:

  • Standardized information on CDKN2A mutations is essential for cancer research.
  • The compiled database facilitates a deeper understanding of p16INK4a's function and its implications in tumorigenesis.
  • Further studies on p16INK4a mutations will advance our knowledge of cancer development and potential therapeutic strategies.
