Reduced expression of DICER, a key enzyme in the miRNA pathway, is frequently associated with aggressive, invasive disease, and poor survival in various malignancies. Regulation of DICER expression is, however, poorly...
DROSHA and its partner DGCR8 form a heterotrimeric complex named Microprocessor, which is essential for microRNA biogenesis. A recent study by Kwon et al. in Cell reveals the structure of a DROSHA construct in complex...
RNA-Dirccicd DNA mcthylation(RdDM)is an imporiant de novo DNA mcthylution pathway in plant.Small interfering RNAs…are requircd to maintain DNAmethylation at only a subect of loct.
During C. elegans apoptosis, the dicer ribonuclease (DCR-1) is cleaved by the cell death protease CED-3 to generate a truncated DCR-1 (tDCR-1) with one and a half ribonuclease III (RNase III) domains, converting...
microRNAs (miRNAs) play important roles in the regulation of gene expression. In Arabidopsis, mature miRNAs are processed from primary miRNA transcripts (pri-miRNAs) by nuclear HYL1/SE/DCL1 complexes that form Dic...
Found in all metazoans, microRNAs or miRNAs are small non-coding RNA of-22 nucleotides in length that completely reshaped our understanding of gene regulation. This new class ofgene regulator is mostly transcribed by ...
The term epigenetics refers to heritable changes not encoded by DNA. The organization of DNA into chromatin fibers affects gene expression in a heritable manner and is therefore one mechanism of epigenetic inheritance...
In less than 10 years since its inception, RNA interference (RNAi) has had extraordinary impact on biomedical science. RNAi has been demonstrated to influence numerous biological and disease pathways. Development an...
