Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Bisphosphonates are the mainstay of therapy worldwide for osteoporosis. They inhibit the activities of the osteoclasts, the bone resorption cells. While bisphosphonates are known to block farnesyl pyrophsophate synthase to exert their anti-resorptive action, the detailed mechanism is not well understood. Examining the change in expression profile before and after bisphosphonate treatment in the osteoclasts might shed some light on the biological pathways that are perturbed.

Bisphosphonates inactivate human EGFRs to exert antitumor actions.

Description
The peroxisome proliferator-activated receptor-coactivator-11 (PGC-11) regulates genes involved in energy metabolism. Increasing adipose tissue energy expenditure through PGC-11 activation has been suggested to be beneficial for systemic metabolism. Pharmacological PGC-11 activators could be valuable tools in the fight against obesity and metabolic disease. Finding such compounds has been challenging partly because PGC-11 is a transcriptional coactivator with no known ligand-binding activities. Importantly, PGC-11 activation is regulated by several mechanisms but protein stabilization is a limiting step as the protein has a short half-life under unstimulated conditions.

Small molecule PGC-1α1 protein stabilizers induce adipocyte Ucp1 expression and uncoupled mitochondrial respiration.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
The demyelination (dmy) rat is a unique spontaneous myelin mutation that exhibits severe myelin breakdown with a late onset of clinical signs. The causative autosomal recessive mutation has been identified at the MRS2 magnesium transporter (Mrs2) gene, which encodes an essential component of the major Mg2+ influx system in mitochondria.

Description
PAX2 is one of nine PAX genes that regulate tissue development and cellular differentiation in embryos. PAX2 promotes cell proliferation, oncogenic transformation, cell lineage specification, migration, and survival. In our previous study, we found that PAX2 is highly expressed in low-grade ovarian serous carcinoma, but its expression in clear cell, endometrioid, and mucinous cell ovarian carcinomas have not been studied. More importantly, the functional role of PAX2 in ovarian cancer is not known.

Description
In order to investigate the function of heme in the regulation of gene expression, we herein examined variations in mRNA levels in ALA-treated cells from control conditions. A comprehensive anal- ysis by RNA sequencing showed marked changes in the expression of various genes. Among the different amounts of mRNA, we identified the novel heme-inducible protein, SRRD. The plant ho- mologue Sensitivity to Red Light Reduced (SRR1) was previously reported to be involved in the regulation of the circadian clock and phytochrome B signaling in Arabidopsis thaliana. We found that SRRD regulated not only heme biosynthesis, but also the expression of clock genes. The involvement of SRRD in the prolif- eration of cells was also demonstrated. Overall design: Examination of ALA-treated versus untreated NIH3T3 cells.
Publication Title
The novel heme-dependent inducible protein, SRRD regulates heme biosynthesis and circadian rhythms.

Description
Inflammatory hepatocellular adenomas (IHCA) are benign liver tumours defined by the presence of inflammatory infiltrates and by the elevated expression of inflammatory proteins in tumour hepatocytes1,2. Here we show a striking activation of the IL6 signalling pathway in this tumour type, and sequencing candidate genes pinpointed this response to somatic gain-of-function mutations in the IL6ST gene that encodes the signalling co-receptor gp130. Indeed, ~70% of IHCA harbour small in-frame deletions that target the binding site of gp130 for IL6, and expression of the most frequent gp130 mutant, Delta-STVY190, in hepatocellular cells activates STAT3 in absence of ligand. Further, analysis of hepatocellular carcinomas revealed rare gp130 alterations always accompanied by -catenin-activating mutations, suggesting a cooperative effect of these signalling pathways in the malignant conversion of hepatocytes. The recurrent gain-of-function gp130 mutations in these human hepatocellular adenomas explains their inflammatory phenotype, and suggest that similar alterations may occur in other inflammatory epithelial tumours with STAT3 activation.

Description
We transduced clonally MLL-AF9 leukemia cells expressing cas9 with sgRNA targeting the jumonji and zinc finger domains of JMJD1C. GFP (MLL-AF9) and TdTomato (sgRNA) double positive cells were sorted on Day 6 after transduction. Total RNA was isolated followed by mRNA selection. cDNA libraries were generated and NextGen Sequencing was performed. Overall design: We performed RNA-seq in mouse MLL-AF9 cas9 cells harboring sgRNA against jumonji and zinc finger domains of JMJD1C or renilla.
