  1. ...relative to miRNAs. This distinction may be reflective of the differences in size, abundance, modifications, and associated Argonaute proteins between tsRNAs and miRNAs. In Drosophila, miRNAs, siRNAs, and piRNAs execute post-transcriptional regulation by primarily binding to AGO1, AGO2, and AGO3/PIWI...
  2. ...whether alteration of IG expression did result in altered proliferation and/or differentiation. We selected several IGs based on their expression pattern in the adipogenic differentiation model and transiently transfected 3T3-L1 cells with siRNAs or cDNAs for 17 and 20 IGs, respectively. Si...
  3. ...and translate them into the output response of cell cycle progression. We next attempted to reconstruct the network of pathways through which the effects of the identified targets were likely enforced. Consequently, we defined the hits identified by our siRNA screen as ‘‘source nodes’’ (Fig. 2A, nodes in dark...
  4. ...). Although most approaches treat miRNA targets as sets of genes, disregarding the complex gene interactions that they form, network-based approaches can integrate protein–protein interactions (PPIs) and other regulators (e.g., transcription factors [TFs]) to achieve a systemic view of the mi...
  5. ...network graphs (Supplemental Figs. 5, 6) show the functional effect of differentially expressed miRNAs on cellular pathways. The large majority of the affected pathways is related to cancer or signal transduction (i.e., Wnt, VEGF, TGF-beta, insulin, phosphatidylinositol signaling, focal adhesion...
  6. ...% of retained introns with cross-linking event. P-value from Fisher's exact test. (F) Bar graphs showing qPCR analysis of UPF1 (top) and IGF2BP1 (bottom) relative mRNA expression levels in MNs (DIV = 21) after being transfected with siRNA targeting UPF1 (UPF1i), IGF2BP1 (IGF2BP1i), or a scrambled control (CTRL...
  7. .... (*) indicates that the motif was identified with medium confidence. (B,C) The majority of the causal transcription factors predicted by IMAGE have an impact on lipid accumulation. (B) Representative images at low and high magnification of Oil Red O staining of hMSCs transfected with the indicated siRNAs...
  8. .... 2017). Over the last decade, advances in bioinformatics and deep sequencing technology have allowed the identification and annotation of tens of thousands of short and long ncRNAs (lncRNAs). These include endogenous microRNAs (miRNAs), small interfering RNAs (endo-siRNAs), PIWI-interacting RNAs (pi...

  9. ...then returned to the abdominal cavity, and the abdominal wall and skin were closed with sutures. The testes were harvested 4 wk after microinjection. All animal experimentation protocols were performed with the approval of the Peking Union Medical College Animal Care and Use Committees. The sequences of siRNAs...
  10. ...; Kagey et al. 2010). To test whether the candidate core TFs play roles in control of ESC identity, we analyzed POU5F1 expression changes and cell nuclei number changes after depletion of each of these TFs using data from a -wide siRNA screen in H1 hESCs (Chia et al. 2010). These data confirm...
