(Submitter supplied) A developmentally regulated RNA binding protein, LIN28A and its homolog LIN28B may share a similar mechanism to regulate the processing of let-7 microRNAs (miRNAs) in embryonic stem cells (ESCs) or certain cancer cells, although their predominant localization is different in cells. However, little is known about the regulatory mechanism of LIN28A for miRNA processing in the nucleus. Here, we show that SET7/9, a known histone methyltransferase, associates with LIN28A in vivo and in vitro. more...

(Submitter supplied) Lin28, a well-known RNA-binding protein, regulates diverse cellular properties. All physiological functions of Lin28A characterized so far have been attributed to its repression of let-7 miRNA biogenesis or modulation of the mRNA translational efficiency. Here we show that Lin28A directly binds to a consensus DNA sequence in vitro and in mouse embryonic stem cells in vivo. ChIP-seq and RNA-seq reveal the enrichment of Lin28A binding around transcription start sites, and a positive correlation between its genomic occupancy and expression of many associated genes. more...

(Submitter supplied) Dicer, which is required for the processing of both microRNAs (miRNAs) and small interfering RNAs (siRNAs), is essential for oocyte maturation. Oocytes express both miRNAs and endogenous siRNAs (endo-siRNAs). To determine whether the abnormalities in Dicer knockout oocytes during meiotic maturation are secondary to the loss of endo-siRNAs and/or miRNAs, we deleted Dgcr8, which encodes a RNA binding protein specifically required for miRNA processing. more...

(Submitter supplied) let-7c and miR-294 were transfected into Dgcr8 -/- miRNA deficient ES cells and RNA was harvested after 12 hours the goal of this study was to identify direct and indirect targets of the let-7c and miR-294 miRNAs, we chose to harvest RNA early at 12 hours to mimize secondary effects due to ES cell differentiation, prior to performing the array experiment we found that at this time point candidate miRNA targets were maximally downregulated by qPCR

(Submitter supplied) Lin28A and its paralog Lin28B are RNA binding proteins that regulate gene expression by inhibition of the maturation of the Per/Pri Let-7 miRNAs family and also via Let-7 independent mechanism. To study the effect of Lin28A ectopic-expression on mouse embryonic development we used a transgenic mice strain that combine a Cre-Lox system and a Tet-On system (herein Lox-stop-Lox-TetOn-Lin28A mice) and enable spatial and temporal control of transgenic Lin28A over-expression. more...

(Submitter supplied) Execution of pluripotency requires progression from the naïve status represented by mouse embryonic stem cells (ESCs) to a state capacitated for lineage specification. This transition is coordinated at multiple levels. Non-coding RNAs may contribute to this regulatory orchestra. We identified a rodent-specific long non-coding RNA (lncRNA) linc1281, hereafter Ephemeron (Eprn), that modulates the dynamics of exit from naïve pluripotency. more...

(Submitter supplied) Somatic mutations affecting DIS3, the catalytic component of the RNA exosome, have been found in up to 18% of patients affected by the hematological cancer multiple myeloma. Here we show that DIS3 targets and degrades the pluripotency factor LIN28B. In cancer cells, DIS3 inactivation leads to enhanced LIN28B expression, thus disrupting the let-7 miRNAs tumor suppressor network and ultimately increasing protein levels of crucial oncogenes such as MYC and RAS. more...

(Submitter supplied) Cancer stem cells (CSC) dictate tumor cell heterogeneity in diverse cancer types and arise, in part, from microRNA (miRNA)-dependent alteration of gene expression. The let-7 miRNA family induces differentiation by silencing genes that maintain stemness and is repressed by the RNA-binding proteins LIN28A/B, which preserve stemness in normal embryonic and malignant cells. Here, we observed that LIN28A/B is undetectable in glioma stem cells (GSC) whereas let-7 and, paradoxically, their target genes are highly expressed. more...

(Submitter supplied) LIN28A is a highly-conserved RNA-binding protein which is known to be involved in embryonic development, stem cell maintenance and proliferation. LIN28A is expressed in various types of cancer, and they are associated with advanced tumor malignancy. In embryonic stem cell, LIN28A specifically binds to let-7 precursors to suppress biogenesis of the let-7 microRNA family. In addition, LIN28A was reported to bind several mRNAs such as Oct4, cyclin A/B and histone H2A to activate their translation. more...

(Submitter supplied) The precise control of microRNA (miRNA) biogenesis is important for various cellular functions, and its dysregulation is often associated with human diseases. We previously reported that Terminal uridylyl transferase 4 (TUT4) down-regulates let-7 miRNA biogenesis by oligo-uridylating let-7 precursor (pre-let-7) in mouse embryonic stem cells and that a pluripotency marker Lin28 promotes a processivity of TUT4. more...
