Definitions related to tumor suppressor genes:
  • A type of gene that makes a protein called a tumor suppressor protein that helps control cell growth. Mutations (changes in DNA) in antioncogenes may lead to cancer.

  • Genes whose loss or deactivation leads to neoplastic transformation; compare with ONCOGENE and PROTOONCOGENE.

  • Tumor Suppressor Genes encode proteins whose functions inhibit expression of tumorigenic phenotypes by holding cellular proliferation in check. When inactivated or lost, a barrier to normal proliferation is removed and deregulated growth is possible.

  • (genes, tumor suppressor) Genes that inhibit expression of the tumorigenic phenotype. They are normally involved in holding cellular growth in check. When tumor suppressor genes are inactivated or lost, a barrier to normal proliferation is removed and unregulated growth is possible.

  • Tumour suppressor gene, any of a class of genes that are normally involved in regulating cell growth but that may become cancer-causing when damaged. Tumour suppressor genes encode for proteins that are involved in inhibiting the proliferation of cells, which is crucial to normal cell development...
