The study of regulatory non-coding RNAs has deepened our understanding of cancer on the molecular and clinical front. MicroRNAs, which encompass over 1000 short, endogenous nucleic acids, include important candidates that drive carcinogenesis. In this discussion, we review the literature on miR-135b, purporting its role as an oncogene in multiple cancers,(More)
Genetic changes in colon cancer are known to parallel the tissue abnormalities associated with the disease, namely adenoma and adenocarcinoma. The role of microRNA dysregulation in dysplastic progression, however, is not well understood. Here, we show that miR-182 and miR-503 undergo sequential up-regulation and drive the progression of colon adenoma to(More)
The CD4 gene is regulated in a stage-specific manner during T cell development, being repressed in CD4(-)CD8(-) double-negative (DN) and CD8 cells, but expressed in CD4(+)CD8(+) double-positive (DP) and CD4 cells. Furthermore, the expression/repression pattern is reversible in developing (DN and DP) thymocytes, but irreversible in mature (CD4 and CD8) T(More)
We have developed a general strategy for creating littermates bearing either a tissue-specific point mutation or deletion in any target gene, and used the method to dissect the roles of Brg, the ATPase subunit of the chromatin-remodeling Brg-associated factor (BAF) complex, in early thymocyte development. We found that a point mutation that inactivates the(More)
