Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Glioma initiating cells (GICs) are considered responsible for the therapeutic resistance and recurrence of malignant glioma. To clarify the molecular mechanism of GIC maintenance/differentiation, we established GIC clones from GBM patient tumors having the potential to differentiate into malignant gliomas in mouse intracranial xenograft, and established an in vitro glioma induction system by using serum stimulation.
Publication Title
Glioma initiating cells form a differentiation niche via the induction of extracellular matrices and integrin αV.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Therapeutic hypothermia is a clinically effective treatment for various hypoxic and ischemic conditions, but the associated molecular mechanisms remain unclear. To gain insight into hypothermia-induced transcriptional response, mouse embryonic fibroblasts were exposed to mild hypothermia (32C) or normothermia (37C) for increasing time periods. We aimed to identify genes with temporally near-monotonic response as the most obvious candidates for mediating the therapeutic effects of hypothermia.

Illumina Genome Analyzer IIx
Description
To explore functionally crucial tumor-suppressive (TS)-miRNAs in hepatocellular carcinoma (HCC), we performed integrative function- and expression-based screenings of TS-miRNAs in six HCC cell lines. The screenings identified seven miRNAs, which showed growth-suppressive activities through the overexpression of each miRNA and were endogenously downregulated in HCC cell lines. Further expression analyses using a large panel of HCC cell lines and primary tumors demonstrated four miRNAs, miR-101, -195, -378 and -497, as candidate TS-miRNAs frequently silenced in HCCs. Among them, two clustered miRNAs miR-195 and miR-497 showed significant growth-suppressive activity with induction of G1 arrest. Comprehensive exploration of their targets using Argonute2-immunoprecipitation-deep-sequencing (Ago2-IP-seq) and genome-wide expression profiling after their overexpression, successfully identified a set of cell-cycle regulators, including CCNE1, CDC25A, CCND3, CDK4, and BTRC. Our results suggest the molecular pathway regulating cell cycle progression to be integrally altered by downregulation of miR-195 and miR-497 expression, leading to aberrant cell proliferation in hepatocarcinogenesis. Identification of miR-195 and miR-497 target genes by sequencing Ago2-binding mRNAs and total mRNAs of miR-195 or miR-497 overexpressed, or non-treated Hep G2 cell. Overall design: Deep sequencing of RNAs in Ago2-IP fraction and mRNAs extracted from miR-195 or miR-497 overexpressed, or non-treated Hep G2 cell.

Description
Roux-en-Y gastric bypass (RYGB) is the most effective therapy for morbid obesity, but it has a ~20% failure rate. We used our established RYGB model in diet-induced obese (DIO) Sprague-Dawley rats, which reproduces human bi-phasic body weight (BW) loss pattern, to determine mechanisms contributing to success (RGYB-S) or failed (RYGB-F) RYGB. DIO rats were randomized to RYGB, sham operated Obese, and sham operated obese pair fed-linked to RYGB (PF) groups. BW, caloric intake (CI) and fecal output (FO) were recorded daily for 90 days, food efficiency (FE) was calculated, and morphologic changes were determined. Gut, adipose and thyroid hormones were measured in plasma. Mitochondrial respiratory complexes in skeletal muscle, expression of energy-related hypothalamic and fat peptides, receptors and enzymes were quantified. A 25% failure rate occurred. RYGB-S, RYGB-F and PF rats vs. Obese showed rapid BW decrease, followed by sustained BW loss in RYGB-S. RYGB-F and PF gradually increased BW. Expression profiling of both CNS (hypothalamus) and peripheral tissues (subcutaneous abdominal fat) strongly supported the involvement of a number of metabolic and feeding-related genes in the differential outcomes.

Description
To investigate the differences of transcriptional activities between AUG-initiated c-Myc and CUG-initiated c-Myc , we performed a transcriptomic analysis using high throoughput RNA sequencing (RNA-seq). Overall design: Total RNA extracted from KMST6 fibroblast cells stably expressing AUG-initiated c-Myc, CUG-initiated c-Myc, and empty vector (negative control) was subjected to RNA-seq analysis. The sequencing libraries generated from the RNA were analyzed by Illumina Hiseq 4000. The sequencing reads were trimmed for adaptor sequence, and low-complexity or low-quality reads were removed. Subsequently, the sequencing reads were aligned to the human reference GRCh38 genome using Gencode v27 annotations by STAR. Read counts per gene were quantified using the HTSeq Python package.

Description
To investigate the downstream targets of eIF5 mimic protein 1 (5MP1), also known as Basic Leucine Zipper and W2 domains 2 (BZW2; Ensembl:ENSG00000136261), we performed a transcriptomic analysis using high throoughput RNA sequencing (RNA-seq). Overall design: Total RNA extracted from HCT116 cells stably expressing 5MP1 and empty vector-transfected negative control HCT116 cells was subjected to RNA-seq analysis. The sequencing libraries generated from the RNA were analyzed by Illumina Hiseq 4000. The sequencing reads were trimmed for adaptor sequence, and low-complexity or low-quality reads were removed. Subsequently, the sequencing reads were aligned to the human reference GRCh38 genome using Gencode v27 annotations by STAR. Read counts per gene were quantified using the HTSeq Python package.

Proliferative diabetic retinopathy (PDR) is a vision-threatening disorder characterized by the formation of cicatricial fibrovascular membranes leading to traction retinal detachment. Despite the recent advance in the treatment of PDR such as vitreoretinal surgery with use of anti-vascular endothelial growth factor (VEGF) drug as an adjunct, it still remains vision-threatening disease.
