Description
Myelodysplastic syndromes (MDS) are a heterogenous group of hematopoietic stem cell disorders characterized by dysplastic blood cell formation and peripheral blood cytopenias. Up to 30% of patients with MDS will progress to a highly chemotherapy-resistant secondary acute myeloid leukemia (sAML). We identified mutations in U2AF1 in MDS patients and patients with U2AF1 mutations are at an increased risk of developing sAML.
Publication Title
Recurrent mutations in the U2AF1 splicing factor in myelodysplastic syndromes.

Description
SOX2 is an oncogene and a core pluripotency transcription factor. SOX2 has multiple roles in various malignancies, in the maintainance of pluripotency and during various stages of embryonic development. Human embryonal carcinoma cells express SOX2 and the loss of this results in their differentiation.

Description
RNA-directed DNA methylation (RdDM) is a transcriptional silencing mechanism mediated by small and long noncoding RNAs produced by the plant-specific RNA polymerases Pol IV and Pol V, respectively. Through a chemical genetics screen with a luciferase-based DNA methylation reporter, LUCL, we found that camptothecin, a compound with anti-cancer properties that targets DNA topoisomerase 1a (TOP1a) was able to de-repress LUCL by reducing its DNA methylation and H3K9 dimethylation (H3K9me2) levels. Further studies with Arabidopsis top1a mutants showed that TOP1a promotes RdDM by facilitating the production of Pol V-dependent long non-coding RNAs, AGONAUTE4 recruitment and H3K9me2 deposition at transposable elements (TEs). Overall design: 5 small RNA libraries were sequenced

Description
A zebrafish forward genetic screen for determinants of susceptibility to Mycobacterium marinum identified a hypersusceptible mutant deficient in the lysosomal hydrolase Cathepsin L that manifests the hallmarks of human lysosomal storage diseases. In uninfected mutants, macrophages progressively accumulate undigested material in their lysosomes, leading to impaired migration and the accumulation of unengulfed cell debris. During mycobacterial infection, these vacuolated macrophages cannot migrate to phagocytose infected macrophages undergoing apoptosis in the tuberculous granuloma. Consequently, unengulfed apoptotic macrophages undergo secondary necrosis causing granuloma breakdown and increased mycobacterial growth. Macrophage lysosomal accumulations similarly impair migration to newly infecting mycobacteria. We find that important aspects of this phenotype are recapitulated in human smokers, who are at increased risk for tuberculosis. A majority of alveolar macrophages from smokers exhibit lysosomal accumulations and do not migrate to Mycobacterium tuberculosis. This incapacitation of highly microbicidal first-responding macrophages may contribute to smokers' susceptibility to tuberculosis. Overall design: A forward genetic screen for zebrafish larvae that are hypersusceptible to Mycobacterium marinum infection identified a mutation in the transcription factor snapc1b at 13: 37996163 (T->C). Individuals of wild type (T/T) and mutant (C/C) were genotyped and pooled respectively for RNA isolation and transcriptome analysis.

Description
We report the mRNA profile of aged mice (24 months old) fed either a control diet or a diet containing Rapamycin (14 ppm) for 3 months. After drug treatement, the hearts of the mice were removed and total mRNA was removed from the tissue. Analysis revealed that there were 700 significantly differentially expressed genes between the control fed group and the Rapamycin diet group by our analysis. Overall design: Heart tissue samples from age-matched control mice (n=10) and rapamycin fed mice (n=10) were extracted for total RNA. The samples were sequenced using Illumina HiSeq 2000 (50 basepair paired-end sequencing). The sequencing yielded quality scores greater than 30 with an average of 10 million reads per sample. 34,293 genes were mapped back to the MGSCv37 C57BL/6J mouse genome (maximum paired distance=300 and minimum=130, minimum number of reads per mapping = 5, maximum number of mismatches= 2, with the reads being mapped to unique sites in the genome).
