Project description:Male germ cell meiosis is essential for generating haploid spermatozoa in mice. Here, we investigate the essential role of DIS3L2 in male germ cell meiosis in mice. Conditional inactivation of DIS3L2 in spermatocytes with Stra8-cre transgenic mice have severely impaired meiotic progression, which results in defective meosis and spermatogenesis associated with a Sertoli cell-only syndrome and adult sterility. RNA-seq analysis reveales that Dis3l2 deficiency causes significant dysregulation of the expression of transcripts in mutant testes. Meiosis-assocaited genes are significantly decreased in the absence of DIS3L2. Therefore, we show that DIS3L2 ribonuclease plays a critical role in germ cell meiosis during spermatogenesis in mice.

Project description:Using conditional knockout mice model, here we report the essential role of DIS3L2 in regulating male germline proliferation, growth and differentiation to ensure male fertility. We document that DIS3L2 is essential for spermatogonial homeostasis. DIS3L2-specific deletion in spermatogonia results in the reduction of the undifferentiated spermatogonial population and the block in transition to the differentiating stage in postnatal testes.

Project description:Liver clock regulates transcription of hepatic genes in response to feeding. To explore the possibility that the microbiome influences this process, we measured the liver transcriptome in normal mice (Specific Pathogen Free or SPF mice) and compared it to the transcriptome in mice lacking microbiota (Germ Free or GF mice) at different time points over 24h. We used microarrays to detail the global programme of gene expression in liver of GF and SPF 10-12 weeks-old male C57Bl/6 male mice. There are 40 liver samples, each from an individual mouse. The samples are from germ free mice (GF) and specific pathogen free mice (SPF). Mice of both types were sacrificed at four time points: Zeitgeber Time 0, 6, 12, and 18. There are five replicates per condition.

Project description:DIS3-like 3'-5' exoribonuclease 2 (DIS3L2) degrades aberrant RNAs, however, its function in tumorigenesis remains largely unexplored.hnRNP U regulates the alternative splicing of pre-mRNA, and our results also showed that RNA promoted the interaction between DIS3L2 and hnRNP U, suggesting that DIS3L2 may be involved in splicing regulation. Thus, we next performed RNA-Seq to investigate whether DIS3L2 regulated pre-mRNA alternative splicing in cancer cells.

Project description:Gut microbiota and the circadian clock both regulate metabolism. The circadian clock and associated feeding rhythms were shown to impact on the microbial community. However, to what extent gut microbiota reciprocally affect daily rhythms of gene expression and physiology in the host remains elusive. Here, we analyzed the transcriptomes of male and female germ-free mice. While this revealed subtle changes in circadian clock gene expression in liver, intestine, and white adipose tissue, germ-free mice showed considerably altered expression of genes associated to rhythmic physiology. Strikingly, absence of microbiome severely compromised liver sex-dimorphism at the transcriptome and metabolome level. Their sex-specific rhythmicity was strongly attenuated. The resulting feminization of male and masculinization of female hepatic gene expression in germ-free animals is likely caused by altered sex-dimorphism in sex and growth hormone secretion, linked to differential activation of xenobiotic receptors. This defines a novel mechanism by which the gut microbiome regulates host metabolism.
