The imprinted H19 lncRNA antagonizes let-7 microRNAs.
Abundantly expressed in fetal tissues and adult muscle, the developmentally regulated H19 long noncoding RNA (lncRNA) has been implicated in human genetic disorders and cancer. However, how H19 acts to regulate gene function has remained enigmatic, despite the recent implication of its encoded miR-675 in limiting placental growth. We noted that vertebrate H19 harbors both canonical and noncanon...
متن کاملLet-7 microRNAs and Opioid Tolerance
This chapter will focus on the role of microRNAs (miRs) in regulating the actions of opioid drugs through the opioid receptors. Opioids, such as morphine, are analgesics that are used for treating many forms of acute and chronic pain. However, their chronic use is limited by undesirable effects such as opioid tolerance. The μ opioid receptor (MOR) is the primary receptor responsible for opioids...
متن کاملH19 lncRNA controls gene expression of the Imprinted Gene Network by recruiting MBD1.
The H19 gene controls the expression of several genes within the Imprinted Gene Network (IGN), involved in growth control of the embryo. However, the underlying mechanisms of this control remain elusive. Here, we identified the methyl-CpG-binding domain protein 1 MBD1 as a physical and functional partner of the H19 long noncoding RNA (lncRNA). The H19 lncRNA-MBD1 complex is required for the con...
متن کاملMolecular Basis for Interaction of let-7 MicroRNAs with Lin28
MicroRNAs (miRNAs) are small noncoding RNA molecules that regulate gene expression. Among these, members of the let-7 miRNA family control many cell-fate determination genes to influence pluripotency, differentiation, and transformation. Lin28 is a specific, posttranscriptional inhibitor of let-7 biogenesis. We report crystal structures of mouse Lin28 in complex with sequences from let-7d, let-...
متن کاملlet-7 and miR-140 microRNAs coordinately regulate skeletal development.
MicroRNAs (miRNAs) play critical roles in multiple processes of skeletal development. A global reduction of miRNAs in growth plate chondrocytes results in defects in both proliferation and differentiation; however, specific microRNAs responsible for these defects have not been identified. In this study, we provide evidence that let-7 miRNAs and microRNA-140 (miR-140), among other miRNAs express...
