Project description:Enhanced expression of the cold-shock protein RNA binding motif 3 (RBM3) is highly neuroprotective both in vitro and in vivo. Whilst upstream signalling pathways leading to RBM3 expression have been described, the precise molecular mechanism of RBM3 induction during cooling remains elusive. To identify temperature-dependent modulators of RBM3, we performed a genome-wide CRISPR-Cas9 knockout screen using RBM3-reporter human iPSC-derived neurons. We found that RBM3 mRNA and protein levels are robustly regulated by several splicing factors, with heterogeneous nuclear ribonucleoprotein H1 (HNRNPH1) being the strongest positive regulator.

Project description:Background: Moderate hypothermia (32oC for 12 – 72 hours) has therapeutic applications, but the mechanisms by which it affects cellular function are unclear. We tested the hypothesis that moderate hypothermia produces broad changes in gene expression by human cells at the level of mRNA. Methods: Acute monocytic leukemia THP-1 cells were incubated under control conditions (37oC) or moderate hypothermia (32oC) for 24 hours. Cellular mRNA was extracted and a cold stress response was confirmed by examining the expression of the cold-inducible gene CIRBP by reverse transcription PCR (RT-PCR). Gene expression analysis was performed on seven sets of samples with Affymetrix U133A chips, using established statistical methods. Sequences were considered to be affected by cold if they showed statistically significant changes in expression and also met published post-hoc filter criteria (changes in geometric mean expression of 2-fold or greater and detection calls of “present” or “marginal” in at least half of the experiments). The changes in expression of a select number of these sequences were further confirmed by PCR. Results: 167 sequences met our prospectively defined criteria for a change in expression; 67 showed increases in expression and 100 showed decreases in expression. Consistent with prior literature, the cold-inducible genes CIRBP and RBM3 showed increases in expression. Functional categories affected by cold stress included genes involved in immune responses, cell growth, proliferation, and differentiation, and metabolism and biosynthesis. Several heat shock proteins (HSPs) showed decreases in expression. Conclusions: Moderate hypothermia produces substantial changes in cellular gene expression, in categories potentially of importance to systemic function. Interestingly, cold exposure without re-warming decreased the expression of several HSPs. Our in vitro findings suggest that moderate hypothermia in vivo might produce physiologically important changes in gene expression by circulating leukocytes. Keywords: Stress response / hypothermia

Project 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 (32°C) or normothermia (37°C) 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.

We aimed to identify genes with temporally near-monotonic response as the most obvious candidates for mediating the therapeutic effects of hypothermia. Hypothermia was compared against normothermia at seven different time-points. Hypothermic and normothermic mouse embryonic fibroblasts (MEF, in 100 mm dishes, one array per time-point) were submitted to gene expression analysis using Mouse Gene 1.0 ST GeneChip® (Affymetrix) microarrays. Differential gene expression analysis was performed with R package DEMI (http://biit.cs.ut.ee/demi/).

Project description:Innate lymphoid cells (ILCs) promote lung inflammation in diseases such as asthma through cytokine production. RNA-binding proteins (RBPs) are critical post-transcriptional regulators of cellular function though the role of RBPs in innate lymphoid cells is unknown. Here, we demonstrate that RNA-binding motif 3 protein (RBM3) is one of the most highly expressed RBPs in Thy1.2+ lung ILCs after fungal allergen challenge and is further induced by epithelial cytokines TSLP and IL-33 in both human and mouse ILCs. Single (rbm3-/-) and double (rbm3-/-rag2-/-) knockout mice exposed via the airway to the asthma-associated fungal allergen Alternaria alternata displayed increases in eosinophilic lung inflammation and ILC activation compared to control mice. In addition to increased Th2 cytokine production, rbm3-/- ILCs produced elevated IL-17A. The negative regulation by RBM3 in ILC responses was direct as purified rbm3-/- ILCs were hyperinflammatory in vitro and in vivo after stimulation with IL-33. Transcriptomic analysis by RNA-sequencing of rbm3-/- lung ILCs showed increased type 2 and 17 cytokines as well as global expression differences in critical cytokines, receptors, transcription factors, and survival transcripts compared with WT ILCs. Importantly, these transcript changes were independent of the numbers of AU-rich elements (AREs) which RBM3 is known to bind. Thus, regulation of ILC responses by RNA-binding proteins offers novel mechanistic insight into lung ILC biology and ILC-driven inflammatory diseases.

Project description:The goal of this study was to identify changes in muscle gene expression that may contribute to loss of adaptability of old muscle. Muscle atrophy was induced in young adult (6-month) and old (32-month) male Brown Norway/F344 rats by two weeks of hind limb suspension (HS) and soleus muscles were analyzed by cDNA microarrays. We conclude that a cold shock response may be part of a compensatory mechanism in muscles undergoing atrophy to preserve remaining muscle mass and that RBM3 may be a therapeutic target to prevent muscle loss.
