The tumor suppressor microRNA let-7 represses the HMGA2 oncogene.

HMGA2, a high-mobility group protein, is oncogenic in a variety of tumors, including benign mesenchymal tumors and lung cancers. Knockdown of Dicer in HeLa cells revealed that the HMGA2 gene is transcriptionally active, but its mRNA is destabilized in the cytoplasm through the microRNA (miRNA) pathway. HMGA2 was derepressed upon inhibition of let-7 in cells with high levels of the miRNA. Ectopi...

Let-7 Represses Carcinogenesis and a Stem Cell Phenotype in the Intestine via Regulation of Hmga2.

Let-7 miRNAs comprise one of the largest and most highly expressed family of miRNAs among vertebrates, and is critical for promoting differentiation, regulating metabolism, inhibiting cellular proliferation, and repressing carcinogenesis in a variety of tissues. The large size of the Let-7 family of miRNAs has complicated the development of mutant animal models. Here we describe the comprehensi...

RAS Oncogene in Brain Tumors, Let-7 MicroRNA Involvement

RAS oncogenes are master regulators of cancers. Somatic mutation in KRAS, HRAS and NRAS genes account for approximately 30% of human cancers. KRAS is the most frequently mutated isoform in RAS-driven cancers. Brain cancers are RAS-driven cancers despite have no RAS mutation or amplification and its pivotal role in brain tumorigenesis has been well documented. Indeed, it’s generally accepted tha...

The let-7 microRNA represses cell proliferation pathways in human cells.

MicroRNAs play important roles in animal development, cell differentiation, and metabolism and have been implicated in human cancer. The let-7 microRNA controls the timing of cell cycle exit and terminal differentiation in Caenorhabditis elegans and is poorly expressed or deleted in human lung tumors. Here, we show that let-7 is highly expressed in normal lung tissue, and that inhibiting let-7 ...

Evolution of the let-7 microRNA Family

The increase of bodyplan complexity in early bilaterian evolution is correlates with the advent and diversification of microRNAs. These small RNAs guide animal development by regulating temporal transitions in gene expression involved in cell fate choices and transitions between pluripotency and differentiation. One of the two known microRNAs whose origins date back before the bilaterian ancest...
