SMYD5 is a regulator of the mild hypothermia response [RNA-Seq]

ABSTRACT: Organisms have homeostatic mechanisms to respond to cold temperature to ensure survival including the activation of the mammalian neuroprotective mild hypothermia response (MHR) at 32°C. Utilizing a forward CRISPR-Cas9 mutagenesis screen, we identify the histone lysine methyltransferase SMYD5 as an epigenetic gatekeeper of the MHR. SMYD5 represses the key MHR gene SP1 at euthermia but not at 32°C. This repression is mirrored by temperature-dependent levels of H3K36me3 at the SP1-locus and globally indicating that the mammalian MHR is regulated at the level of histone modifications. We identified additional SMYD5-temperature dependent genes suggesting a broader MHR-related role for SMYD5. Our study provides an example of how the epigenetic machinery integrates environmental cues into the genetic circuitry of mammalian cells and suggests novel therapeutic avenues for neuroprotection after catastrophic events.

Tissue culture model of 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.

SMYD5 catalyzes histone H3 lysine 36 trimethylation at promoters

Project description:Histone mark, one carrier of epigenetic information, regulates the gene expression in cells. Studies have shown that H3K36me3 is mainly catalyzed by SETD2 to be deposited at gene body regions in mammalian cells. Here, we profile the distributions of H3K36me3 in native cells and uncover that H3K36me3 is also enriched at the promoters beyond the gene body regions. We identify SMYD5 as one methyltransferase responsible for the enrichment of H3K36me3 at promoters. Through RNA polymerase II, SMYD5 is recruited to chromatin to regulate H3K36me3 and gene expression. The enzymatic activity of SMYD5 is dependent on its C-terminal glutamic acid rich domain. Depletion of C-terminal domain reduces the reestablishment of H3K36me3 at promoters when Smyd5 is over-expressed in Smyd5 knockout cells. Furthermore, elevated Smyd5 expression contributes to the tumorigenesis of liver hepatocellular carcinoma. Together, our study reveals SMYD5 as the H3K36me3 methyltransferase at promoters to regulate the gene expression, providing important insights into the localization and function of H3K36me3.

Identification of novel diagnostic markers for fatal hypothermia by body temperature-dependent gene expression analysis in rats

Project description:Diagnosis of fatal hypothermia is considered to be difficult in forensic practice. In this study, in order to identify novel molecular markers of fatal hypothermia, we made rat models of mild, moderate and severe hypothermia, and performed body temperature-dependent gene expression analysis in illiopsoas muscle using next-generation sequencing.
