Cell proliferation, cell loss and expression of bcl-2 and p53 in human pulmonary neoplasms
1Department of Pathology, Aberdeen University Medical School, Foresterhill, UK.
Abstract:
Immunohistochemical staining of bcl-2 and p53 proteins was compared with thymidine labelling index (TLI) and cell loss factor (O) in lung cancer. Neither bcl-2 nor p53 overexpression was associated with high cell loss but strong bcl-2 staining was associated with higher TLI. Concomitant strong p53 and bcl-2 expression, not the usual inverse relationship, plus high cell-loss factor was present in three neuroendocrine carcinomas. Other factors presumably have a role in controlling cell death in these tumours.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
