Abstract:
We performed loss of heterozygosity (LOH) analysis on matched lymph nodes before and after progression of follicular lymphoma (FL), and found novel LOH on chromosome arm 12p. This LOH has not been previously reported in association with FL transformation. Other sites of frequent LOH include chromosome arms 6q and 9p. LOH was observed in both transformed FL and relapse FL. These data suggest that altered tumor suppressor genes exist on 6q, 9p, and 12p that have an important role in the progression of FL. Genetic changes accumulated in relapsed FL in the absence of histological changes compared to initial diagnosis.

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...

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Cancer-Critical Genes II: Tumor Suppressor Genes
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...
