Description
The Gata2 transcription factor is a pivotal regulator of hematopoietic stem cell (HSC) development and maintenance. Gata2 functions in the embryo during endothelial cell to hematopoietic cell transition (EHT) to affect hematopoietic cluster, HPC and HSC formation. Although previous studies of cell populations phenotypically enriched in HPCs and HSCs show expression of Gata2, there has been no direct study of Gata2 expressing cells during normal hematopoiesis. In this study we generate a Gata2 Venus reporter mouse model with unperturbed Gata2 expression to examine the hematopoietic function and transcriptome of Gata2 expressing and nonexpressing cells. Overall design: Gata2Venus- HPCs 1 replicate, Gata2Venus+ HPCs 1 replicate

Description
Newborn Balb/c mice were injected with 1.5x10^6 fluorescent-forming units (ffu) of Rhesus rotavirus type-A or 0.9% NaCl (normal saline) intraperitoneally within 24 hours of birth to induce experimental model of biliary atresia. The extrahepatic bile ducts including gallbladder were microdissected en bloc at 3, 7 and 14 days after rhesus rotavirus or saline injection. GeneChip Mouse Gene 1.0 ST Array (Affymetrix, CA) were used to screen mRNAs whose expression was differently regulated after rhusus rotavirus injection compare to the normal saline controls.

Description
BACKGROUND: Young age at portoenterostomy has been linked to improved outcome in biliary atresia, but pre-existing biological factors may influence the rate of disease progression. In this study, we aimed to determine whether molecular profiling of the liver identifies stages of disease at diagnosis. METHODS: We examined liver biopsies from 47 infants with biliary atresia enrolled in a prospective observational study. Biopsies were scored for inflammation and fibrosis, used for gene expression profiles, and tested for association with indicators of disease severity, response to surgery, and survival at 2 years. RESULTS: Fourteen of 47 livers displayed prominent features of inflammation (N=9) or fibrosis (N=5), with the remainder showing similar levels of both simultaneously. Differential profiling of gene expression of the 14 livers displayed a unique molecular signature containing 150 gene probes. Applying prediction analysis models, the probes classified 29 of the remaining 33 livers into inflammation or fibrosis. Molecular classification into the two groups was validated by the findings of increased hepatic population of lymphocyte subsets or tissue accumulation of matrix substrates. The groups had no association with traditional markers of liver injury or function, response to surgery, or complications of cirrhosis. However, infants with an inflammation signature were younger, while those with a fibrosis signature had decreased transplant-free survival. CONCLUSION: Molecular profiling at diagnosis of biliary atresia uncovers a signature of inflammation or fibrosis in most livers. This signature may relate to staging of disease at diagnosis and has implications to clinical outcomes.

Description
To functionally characterize the role of miR-17 family in HCC, lentiviral vector-based miR inhibitor TuD was used to inhibit miR-17 family of microRNAs in HepG2 and SK-Hep1 HCC cell lines Overall design: Methods: HepG2 and SK-Hep1 HCC cell lines were acquired from American Type Culture Collection (ATCC) and miR-17 TuD or NC TuD expressing lines were generated. mRNA profiling of miR-17 TuD or NC TuD expressing samples was performed using Illumina NGS. Total RNA was extracted as per manufacturer’s instructions (RNeasy kit, Qiagen). RNA quality was assessed using BioAnalyzer (Agilent). mRNA expression profiles were determined using next-generation sequencing (NGS) on the Illumina HiSeq 2000 platform producing 50bp paired-end reads. Bowtie/TopHat suites were used to align the reads to mouse genome or transcriptome and RSEM were used to quantify gene abundances. Gene level counts were then normalized with the R/Bioconductor package limma using the voom/variance stabilization method.
