Chromosomal deletions and tumor suppressor genes in prostate cancer.

Abstract excerpt

Chromosomal deletion appears to be the earliest as well as the most frequent somatic genetic alteration during carcinogenesis. It inactivates a tumor suppressor gene in three ways, that is, revealing a gene mutation through loss of heterozygosity as proposed in the two-hit theory, inducing haploinsufficiency through quantitative hemizygous deletion and associated loss of expression, and truncating a genome by...
