Identifying Compounds that Alleviate Acute Hypoxic Stress by Fast-tracking Cellular Adaptation

Project description:Severe acute hypoxic stress is a major contributor to the pathology of human diseases, including ischemic disorders. Current treatments focus on managing consequences of hypoxia, with few addressing cellular adaptation to low-oxygen environments. Here, we hypothesize that accelerating hypoxia adaptation could provide a strategy to alleviate acute hypoxic stress. We developed a high-content phenotypic screening platform to identify compounds that fast-track adaptation to hypoxic stress. Our platform captures a high-dimensional phenotypic hypoxia response trajectory consisting of normoxic, acutely stressed, and chronically adapted cell states. Leveraging this trajectory, we identify compounds that phenotypically shift cells from the acutely stressed towards the adapted state, revealing mTOR/PI3K or BET inhibition as strategies to induce this phenotypic shift. Importantly, our compound hits promote the survival of liver cells exposed to ischemia-like stress, and rescue cardiomyocytes from hypoxic stress. Our platform offers a general, target-agnostic strategy to accelerate cellular adaptation, applicable across various stress conditions.

Six homeoproteins and a linc-RNA cooperate at the fast MYH locus to lock terminal fast myofibre phenotype

Project description:Thousands of long intergenic noncoding RNAs (lincRNAs) are encoded by the mammalian genome, which were reported to have multiple biological functions as transcriptional activators acting in cis 1 or trans 2, transcriptional repressors 3,4 or miRNAs decoys 5,6. However, the function of most lincRNAs has not yet been identified in vivo. Here, we demonstrate a role for linc-MYH, a novel long intergenic noncoding RNA, in adult fast-type myofibre specialization. Skeletal myofibre fast and slow phenotypes are established through differential expression of numerous fibre-specific genes7. We show linc-MYH and the fast MYH genes share a common enhancer located in the fast MYH genes locus and regulated by the Six1 homeoproteins. Muscle-specific Six1 mutant mice show increased expression of slow-type genes, and downregulation of linc-MYH and fast-type genes. linc-MYH function revealed by in vivo knockdown and wide transcriptomic analysis, is in fine to prevent expression of genes ensuring slow muscle contractile properties, and to increase fast-type muscle gene expression in fast-type myofibres. Thus, formation of efficient fast sarcomeric units and appropriate Ca++ cycling and excitation/contraction/relaxation coupling in fast- myofibres is achieved through the coordiante control of fast MYHs and linc-MYH expression by a Six bound enhancer.

Soybean fast neutron genotyping: 700k Forward genetics

Project description:CGH was used to compare induced structural variation among soybean fast neutron lines, developed in background M92-220. 114 different soybean fast neutron lines were hybridized against the parental reference genotype M92-220. The soybean tiling array consists of 700k probes, spaced at approximately 1.1 kb intervals.

Fast and chronic ethanol tolerance - time course

Project description:To better understand the molecular mechanisms underlying ethanol action we have developed an assay system to study sensitivity and fast and chronic tolerance to the sedative effects of ethanol. Flies developed fast ethanol tolerance after single exposure to 50% of ethanol vapor for 40 min. Flies can also develope chronic ethanol tolerance after 5x 40 min exposure to 50% ethanol vapor interspersed with 4x 80 min exposure to 10% ethanol vapor. We used microarray analysis to identify genes involved in the development of fast and chronic ethanol tolerance in Drosophila. More than 600 hundred genes were found to have changed their expression level in response to different ethanol treatment. Among these genes, Homer was picked for further study and is demonstrated that its expression in ellipsoid body is critical for the normal sensitivity and fast toleance to ethanol. Keywords: time course
