Description
Smoking is a significant risk factor for lung cancer, the leading cause of cancer-related deaths worldwide. While microRNAs are regulators of many airway gene-expression changes induced by smoking, their role in modulating changes associated with lung cancer in these cells remains unknown. Here, we use next-generation sequencing of small RNAs in the airway to identify miR-4423 as a novel primate-specific microRNA associated with lung cancer and expressed primarily in mucociliary epithelium. The endogenous expression of miR-4423 increases as bronchial epithelial cells undergo differentiation into mucociliary epithelium in vitro and its overexpression during this process causes an increase in the number of ciliated cells. Furthermore, expression of miR-4423 is reduced in most lung tumors and in cytologically normal epithelium of the mainstem bronchus of smokers with lung cancer. In addition, ectopic expression of miR-4423 in a subset of lung cancer cell lines reduces their anchorage-independent growth and significantly decreases the size of the tumors formed in a mouse xenograft model. Consistent with these phenotypes, overexpression of miR-4423 induces a differentiated-like pattern of airway epithelium gene expression and reverses the expression of many genes that are altered in lung cancer. Together, our results indicate that miR-4423 is a novel regulator of airway epithelium differentiation and that the abrogation of its function contributes to lung carcinogenesis.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Arsenic is a potent environmental toxin and a cause of numerous health problems. Most studies have assumed that arsenic-induced changes in mRNA levels result from effects on gene transcription. The influence of arsenic on post-transcriptional regulation, another important locus of gene expression control, has remained largely unexplored.

- Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
Members of the tristetraprolin (TTP) family of CCCH tandem zinc finger proteins can bind directly to AU-rich elements in mRNAs and promote transcript deadenylation and decay. The yeast Schizosaccharomyces pombe expresses a single TTP family member, Zfs1p, that has been linked to the mating response pathway and septum formation. We showed previously that Zfs1p can bind to and promote the destabilization of AU-rich element-containing transcripts. In this study, we identified additional target transcripts by comparing transcript levels in wild type and zfs1 mutant yeast, using deep sequencing and microarray approaches. We also used direct RNA sequencing to determine the locations of the polyA tails in both wild type and mutant strains, and to confirm the presence of potential Zfs1p target sequences within the mRNA. These studies identified a set of transcripts containing potential Zfs1p binding sites that accumulated significantly in the zfs1 mutants; a subset of these turned over more slowly in the zfs1 mutant strain, and bound directly to Zfs1p in co-immunoprecipitations. One apparent direct target encodes the transcription factor Cbf12p, which is known to increase cell-cell adhesion and flocculation when over-expressed. Studies of zfs1 and cbf12 double mutants demonstrated that the increased flocculation seen in zfs1 mutants is due, at least in part, to a direct effect on the turnover of cbf12 mRNA, leading in turn to changes in the levels of its transcriptionally regulated genes. These data suggest that Zfs1p can both directly and indirectly regulate the levels of transcripts involved in cell-cell adhesion in this species.

Description
Mutations in the RUNX1 gene (RUNX1mut) have been established in myelodysplasia (MDS), de novo and secondary acute myeloid leukaemia (AML), and are in general associated with an unfavourable clinical outcome. Familial RUNX1 mutations are associated with familial thrombocytopenia and these patients have a predisposition to AML development. However, a number of studies have been performed so far in mice which might be distinct from the human hematopoietic system. Therefore we studied the cellular phenotypes, the RUNX1 binding pattern and expression profile induced by RUNX1mut in cord blood (CB) CD34+ cells and induced pluripotent stem cell (iPSC) and compared these findings to primary RUNX1mut AML's. Overall design: A total of nine samples were subject to RNA-Seq including RUNX1mut-transduced cord blood CD34 cells and time-course iPSCs.
