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
Ammonia is a toxic by-product of metabolism that causes cellular stress. Although a number of proteins are involved in adaptive stress response, specific factors that counteract ammonia-induced cellular stress and regulate cell metabolism that facilitate survival against toxicity have yet to be identified. We demonstrated that hypoxia-inducible factor-1 (HIF-1) is stabilised and activated by ammonia stress. HIF-1 activated by ammonium chloride compromises ammonia-induced apoptosis. Furthermore, we identified glutamine synthetase (GS) as a key driver of cancer cell proliferation and glutamine-dependent metabolism under ammonia stress in ovarian cancer stem-like cells expressing CD90. Interestingly, activated HIF-1 counteracts glutamine synthetase function in glutamine metabolism by facilitating glycolysis and elevating glucose dependency. Our studies reveal the hitherto unknown functions of HIF-1 in biphasic ammonia stress management in cancer stem-like cells. GS facilitates proliferation and HIF-1 contributes to metabolic remodelling in cellular energy usage resulting in attenuated proliferation but conversely promoting cell survival.

Description
To establish effective multitargeted KRAS pathway therapy, we analyzed mediators of acquired resistance to chronic momelotinib and MEK inhibitor exposure in A549 cells. Since inhibitor resistance was completely reversible after drug withdrawal for several passages, suggesting epigenetic reprogramming, we investigated whole mRNA expression profiles in A549, momelotinib and selumetinib resistant (MSR)-A549 cells and MSR-A549 cells following drug withdrawal for 10 days. In parallel, we also examined mRNA expression profiles of MSR-A549 cells treated with the BET inhibitor JQ1, to identify specific targets regulated by H3K27 acetylation. Overall design: mRNA profile of MSR-A549 cells with or without JQ1 treatment.

Description
We asked whether combining Notch and VEGF blockade would enhance suppression of tumor angiogenesis and growth, using the NGP neuroblastoma model. NGP tumors were engineered to express a Notch1 decoy construct (N1D), which restricts Notch signaling, and then treated with either the anti-VEGF antibody bevacizumab or vehicle. Combining Notch and VEGF blockade led to blood vessel regression, increasing endothelial cell apoptosis and disrupting pericyte coverage of endothelial cells. Combined Notch and VEGF blockade did not affect tumor weight, but did additively reduce tumor viability. Our results indicate that Notch and VEGF pathways play distinct but complementary roles in tumor angiogenesis, and show that concurrent blockade disrupts primary tumor vasculature and viability further than inhibition of either pathway alone.

Description
During kidney development segmented epithelia of the nephron derive from progenitor cells in the metanephric mesenchyme after induction by secreted molecules from the ureteric bud. We have identified three distinct inductive activities from a ureteric bud cell line. These include leukemia inhibitory factor (LIF), neutrophil gelatinase-associated lipocalin (NGAL) and an active fraction currently referred to as ANX. Each of these activities induces segmented nephron epithelia in isolated rat metanephric mesenchyme over a time period of 7 days. This study was designed to characterize the temporal sequence of gene expression in the course of the conversion process induced by each of the distinct inducers.
