Project description:To investigate the functional difference between rs1260326:C>T in the regulation of lipogenesis in the liver, we established human induced pluripotent stem cell lines from GCKR CC and GCKR TT variants.
Project description:Nitrogen is a key factor impacting plant physiological processes and protein abundance. Although many proteins were changed substantially in poplar under N deficiency, the post-translational modifications in male and female poplars are still unclear. Therefore, we selected male and female poplars and analysed the changes of protein phosphorylation in response to N-deficient conditions.
Project description:Growth hormone (GH)-regulated transcription factors, notably STAT5 and BCL6, play a major role in regulating genes showing sex differences in expression in mouse liver, primarily through their effects in male liver, where male-biased genes are up regulated and many female-biased genes are actively repressed. Here we investigate whether complementary mechanisms, involving up regulation of female-biased genes and down regulation of male-biased genes occur in female liver. To address this question, we identified genes regulated by Cux2, a highly female-specific transcription factor that is repressed in male liver and is induced by the female plasma GH pattern in female liver. ChIP-seq analysis identified Cux2 binding sites in female liver only, where they are enriched at sites of male-biased DNase hypersensitivity and at genomic regions showing male-enriched STAT5 binding. Cux2 binding sites were enriched at genes repressed by adenoviral-Cux2, but not at genes induced by adenoviral-Cux2 (see GSE35897), indicating a direct binding mechanism in Cux2 repression but not in Cux2-dependent gene induction.

Project description:CircRNA microarray was conducted to further explore the underlying circRNA expression alterations in extramedullary infiltration (EMI) of AML. 4 matched samples from EMI, non-EMI AML patients and healthy volunteers were selected. Mononuclear cells from 12 bone marrow samples were separated according to protocols. RNA was then extracted and hybridization for further microarray analysis.
Project description:∼40,000 HNF6 binding sites were identified in mouse liver chromatin, including several thousand sites showing significant differences in level of HNF6 binding between male and female mouse liver. These sex-biased HNF6 binding sites showed strong enrichment for sex-biased DNase hypersensitive sites and for proximity to genes showing local sex-biased chromatin marks and a corresponding sex-biased expression. ~90% of genome-wide CUX2 binding sites identified previously in female mouse liver (Conforto TL, Zhang Y, Sherman J, Waxman DJ., Mol Cell Biol. 2012;32(22):4611-4627) were also bound by HNF6, giving evidence for genome-wide competition between HNF6 and CUX2 for chromatin binding in female mouse liver. These HNF6/CUX2 common binding sites were enriched for genomic regions more accessible in male than in female mouse liver chromatin, and showed strongest enrichment for male-biased genes, suggesting HNF6 displacement by CUX2 as a mechanism to explain the observed CUX2 repression of male-biased genes in female liver. However, HNF6 binding was sex-independent at a majority of its binding sites, and peak regions of HNF6 binding were frequently associated with co-binding by multiple other liver transcription factors, consistent with HNF6 playing a global regulatory role in both male and female liver.
