(Submitter supplied) In this study, we investigated the role of LIN28 in intestinal tumor initiation and invasive progression. We generated animal models with just intestinal LIN28B overexpression, or in combination with Apcmin/+ background. The animals develop intestinal and colorectal tumors with histology ranging from adenoma to adenocarcinoma.

(Submitter supplied) Mutations in TGFBR2, a component of the transforming growth factor (TGF)-β signaling pathway, occur in high-frequency microsatellite instability (MSI-H) colorectal cancer (CRC). In mouse models, Tgfbr2 inactivation in the intestinal epithelium accelerates the development of malignant intestinal tumors in combination with disruption of the Wnt-β-catenin pathway. However, no studies have further identified the genes influenced by TGFBR2 inactivation following disruption of the Wnt-β-catenin pathway. more...

(Submitter supplied) Wilms Tumor, the most common pediatric kidney cancer, evolves from the failure of terminal differentiation of the embryonic kidney. Here we show that over-expression of the heterochronic regulator Lin28 during kidney development in mice markedly expands nephrogenic progenitors by blocking their final wave of differentiation, ultimately resulting in pathology highly reminiscent of Wilms tumor.

Analysis of kidney tumors from Lin28a transgenics at 5 weeks and 4 months of age. Overexpression of heterochronic regulator Lin28 during kidney development promotes Wilms tumor formation. Results provide insight into the role of Lin28 in Wilms tumor formation.

(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) To identify mechanisms involved in growth and glucose metabolism, we performed whole genome mRNA expression analysis in five week old quadraceps muscle from 2 CD-1 background male Lin28A Tg and 2 WT littermates (all male) in which there was 7 fold overexpression of Lin28A, a RNA binding protein that enhances Igf2 translation and suppresses the let-7 microRNA biogenesis.

(Submitter supplied) RNA binding protein (RBP) expression is finite. For RBPs that are vastly outnumbered by their potential target sites, a simple competition for binding can set the magnitude of post-transcriptional control. Here we show that LIN28, best known for its direct regulation of let-7 miRNA biogenesis, is also indirectly regulated by its widespread binding of non-miRNA transcripts. Approximately 99% of LIN28 binding sites are found on non-miRNA transcripts, like protein coding and ribosomal RNAs. more...

(Submitter supplied) We report the mapping of LIN28B binding to RNA in HEK293A at various LIN28B expression levels using enhanced CLIP. We provide small RNA sequencing data regarding miRNA expression in HEK293A and those miRNAs bound by AGO2. We also profile the effect of LIN28B expression on transcriptome-wide ribosome occupancy in HEK293A via RNA-seq. Finally, we provide orthogonal regulatory data by profiling the effect of LIN28B expression on transcriptome-wide ribosome occupancy in NIH3T3 via RNA-seq.

(Submitter supplied) We sought to elucidate functions of LIN28B and potential mechanisms whereby it may promote metastasis by comparing the gene expression profile of LIN28B metastases to primary tumors. Accordingly, we performed microarray analysis on total RNA isolated from empty vector tumors, LIN28B-LoVo tumors, and LIN28B-LoVo metastases

(Submitter supplied) We sought to elucidate the molecular mechanisms whereby LIN28B functions by comparing the gene expression profile of cells constitutively expressing LIN28B to empty vector controls. Accordingly, we performed microarray analysis on total RNA isolated from empty vector LoVo and LIN28B-expressing LoVo colon cancer cell lines.

(Submitter supplied) Aim: RNA binding proteins (RBPs) are expressed broadly during both development and malignant transformation, yet their mechanistic roles in epithelial homeostasis or as drivers of tumor initiation and progression are incompletely understood. Method: Here we describe a novel interplay between RBPsLIN28B and IMP1 in intestinal epithelial cells. Ribosome-profiling and RNA-sequencing identifies IMP1 as a principle nodefor gene expression regulation downstream of LIN28B. more...
