Differential effects of DNA tumor virus nuclear oncogene products on adipocyte differentiation
Abstract:
We have introduced SV40 and polyoma large T antigen- and adenovirus-type 12 E1A genes into mouse 3T3-L1 preadipocyte cells to study the ability of various nuclear oncogene products to modulate cell differentiation. Clones expressing E1A products could differentiate into adipocytes faster than the control in spite of the absence of adipogenic inducers, as measured by the appearance of lipid droplets microscopically and by staining accumulated triglycerides with oil red O. However, clones expressing SV40 and polyoma large T antigens could not differentiate even if they were exposed to the inducers.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
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...
