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...
متن کاملRAS Is Regulated by the let-7 MicroRNA Family
MicroRNAs (miRNAs) are regulatory RNAs found in multicellular eukaryotes, including humans, where they are implicated in cancer. The let-7 miRNA times seam cell terminal differentiation in C. elegans. Here we show that the let-7 family negatively regulates let-60/RAS. Loss of let-60/RAS suppresses let-7, and the let-60/RAS 3'UTR contains multiple let-7 complementary sites (LCSs), restricting re...
متن کاملThe primary target of let-7 microRNA.
The let-7 miRNA (microRNA) is an essential regulator of development from nematode worms to humans. Altered expression of let-7 results in larval arrest or lethality in Caenorhabditis elegans. Likewise, under- or over-expression of let-7 in human cells can result in cellular overproliferation or halted cell division respectively. Thus the biogenesis of this critical miRNA is controlled at multip...
متن کاملMicroRNA let-7 in the spotlight: Role in innate immunity
Innate immunity forms the first line of host defense. It is quick and usually shapes the adaptive immune responses which clear off the pathogens. However, dysregulated innate immune responses can lead to excessive inflammation which causes significant damage to the host. As a result, innate immune responses are tightly regulated. In this review, we focus on mechanisms by which microRNA let-7 re...
متن کاملDisease specific enrichment of circulating let-7 family microRNA in MuSK+ myasthenia gravis
Myasthenia gravis (MG) patients with antibodies against the muscle specific tyrosine kinase (MuSK+) have predominantly involvement of cranio-bulbar muscles and do not display thymus pathology, as do acetylcholine receptor antibody seropositive (AChR+) MG patients. In search of novel biomarkers for MuSK+ MG, we evaluated circulating serum microRNAs. Four analyzed microRNAs were specifically elev...
