Identification of MicroRNA-Related Tumorigenesis Variants and Genes in the Cancer Genome Atlas (TCGA) Data.

Genes (Basel) 2020 08 19;11(9). Epub 2020 Aug 19.

USF Genomics & College of Public Health, University of South Florida, Tampa, FL 33612, USA.

MicroRNAs (miRNAs) are a class of small non-coding RNA that can down-regulate their targets by selectively binding to the 3' untranslated region (3'UTR) of most messenger RNAs (mRNAs) in the human genome. Single nucleotide variants (SNVs) located in miRNA target sites (MTS) can disrupt the binding of targeting miRNAs. Anti-correlated miRNA-mRNA pairs between normal and tumor tissues obtained from The Cancer Genome Atlas (TCGA) can reveal important information behind these SNVs on MTS and their associated oncogenesis.

Cbfβ2 deficiency preserves Langerhans cell precursors by lack of selective TGFβ receptor signaling.

J Exp Med 2017 Oct 16;214(10):2933-2946. Epub 2017 Aug 16.

Laboratory for Transcriptional Regulation, RIKEN Center for Integrative Medical Sciences, Yokohama, Japan

The mouse Langerhans cell (LC) network is established through the differentiation of embryonic LC precursors. BMP7 and TGFβ1 initiate cellular signaling that is essential for inducing LC differentiation and preserving LCs in a quiescent state, respectively. Here we show that loss of Cbfβ2, one of two RNA splice variants of the gene, results in long-term persistence of embryonic LC precursors after their developmental arrest at the transition into the EpCAM stage.
