Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Pathways that govern normal stem cell (SC) function are often subverted in cancer. Here, we report the isolation to near purity of human normal mammary SC (hNMSCs), from cultured mammospheres, based on their ability to retain the lipophilic dye PKH26 as a consequence of their quiescent nature. We demonstrated that PKH26-positive cells possess all the characteristics of hNMSCs. The transcriptional profile of PKH26-positive cells (hNMSC signature) was able to predict biological and molecular features of breast cancers. By using markers of the hNMSC signature, we could prospectively isolate SCs from the normal gland and from breast tumors. Poorly-differentiated aggressive (G3) cancers displayed higher content of prospectively isolated cancer SCs, than well-differentiated less aggressive (G1) cancers. By comparing G3 and G1 tumors in xenotransplantation experiments, we directly demonstrated that G3s are enriched in cancer SCs. Our data support the notion that the heterogeneous phenotypical and molecular traits of human breast cancers are a function of their SC content.

Description
Among acute myeloid leukemias (AML) with normal karyotype (CN-AML), NPM1 and CEBPA mutations define WHO provisional entities accounting for ~60% of cases, but the remaining ~40% remains poorly characterized. By whole exome-sequencing (WES) of one CN-AML patient lacking mutations in NPM1, CEBPA, FLT3, MLL-PTD and IDH1, we newly identified a clonal somatic mutation in BCOR (BCL6 co-repressor), a gene located in chromosome X. Further analyses showed that BCOR mutations occurred in 11/262 (4.2%) CN-AML cases and represented a substantial fraction (14/82, 17.1%) of CN-AML patients showing the same genetic background as the index patient subjected to WES.

Description
This study aims to investigate the role of microRNA-30c on hepatic and metabolic gene expression and physiology Overall design: For this experiment, we used male C57BL/6 mice. At an age of 8 weeks, we started them on Western diet for one month and then injected them with either PBS or increasing dose of Scr or miR-30c mimic (2.5, 5.0, and 7.5 mg/kg) for 6 weeks. Liver from these mice were harvested and flash frozen. RNA from the livers of these mice were extracted and RNA-seq was performed.
