Abstract:
HMG-I/Y is overexpressed in human cancer, although a direct role for this gene in transformation has not been established. We generated transgenic mice with HMG-I targeted to lymphoid cells. All seven informative founder HMG-I mice developed aggressive lymphoma by a mean age of 4.8 months. Tumors express T-cell markers and are transplantable. We also demonstrate that HMG-I mRNA and protein are increased in human acute lymphocytic leukemia samples. Our results show that HMG-I functions as an oncogene and suggest that it contributes to the pathogenesis of leukemia and other cancers with increased HMG-I expression.

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.

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
