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.

Sonicated, cross-linked liver nuclear chromatin was then used to identify Cux2 binding sites by ChIP-Seq using antibody specific to Cux2, amino acids 356 to 415

Project description:We identified genes expressed in mouse liver that are regulated by Cux2, a highly female-specific liver transcription factor whose expression is regulated by sex-dependent plasma GH patterns. Using siRNA to knockdown Cux2 expression in female liver, we show that female specific genes are predominantly repressed by Cux2 knockdown. In contrast, similar numbers of male-biased genes are repressed as are induced by Cux2 knockdown. A scrambled, non-specific siRNA was used as a control.

Project description:We identified genes expressed in mouse liver that are regulated by Cux2, a highly female-specific liver transcription factor whose expression is regulated by sex-dependent plasma GH patterns. Using adenovirus to overexpress Cux2 (Adeno-Cux2) in male liver, we show that Cux2 represses ~35% of male-biased genes and induces/de-represses ~35% of female-biased genes. Adeno-CMV was used as a control for adenoviral infection. (Published in: TL Conforto et al 2012, Mol Cell Biol. 2012, 32:4611-4627. PubMed PMID: 22966202; PMCID: PMC3486175)

(Published in Molec Cell Biology, TL Conforto et al, 2012) Liver RNA isolated from the following 3 groups of mice was used in the present study: (1) 8 wk old female mice treated with non-specific siRNA control (n = 13; 6 or 7 per each pool); (2) 8 wk old female mice treated with Cux2 siRNA and euthanized 5 days later (n = 5; 2 or 3 per each pool); (3) 8 wk old female mice treated with Cux2 siRNA and euthanized 8 days later (n = 4; 2 per each pool). These RNA pools were used in two separate sets of competitive hybridization experiments: 1) 8 wk non-specific siRNA treated vs. 8 wk Cux2 siRNA treated for 5 days; 2) 8 wk non-specific siRNA treated vs. 8 wk Cux2 siRNA treated for 8 days. Fluorescent labeling of RNA and hybridization of the Alexa 555-labeled (green) and Alexa 647-labeled (red) RNA samples to Agilent Mouse Gene Expression 4x44k v1 microarrays (Agilent Technology, Palo Alto, CA; catalog # G4122F-014868) were carried out, with dye swapping for each of the two hybridization experiments to eliminate dye bias. Two microarrays, one for each mixed cDNA sample, were hybridized for each of the two fluorescent reverse pairs, giving a total of 4 microarrays.

(Published in Molec Cell Biology, TL Conforto et al, 2012) Liver RNA isolated from the following eight groups of mice was used in the present study: (1) 8 wk old untreated male (M) mice (n = 10; 5 per each pool); (2) 8 wk old untreated female mice (F) mice (n = 11; 5 or 6 per each pool); (3) 8 wk old male mice treated with Adeno-Cux2 and euthanized 5 days later (n = 12; 6 per each pool); (4) 8 wk old female mice treated with Adeno-Cux2 and euthanized 5 days later (n = 8; 4 per each pool); (5) 8 wk old male mice treated with Adeno-CMV and euthanized 5 days later (n = 13; 6 or 7 per each pool); (6) 8 wk old female mice treated with Adeno-CMV and euthanized 5 days later (n = 7; 3 or 4 per each pool); (7) 8 wk old male mice treated with Adeno-Cux2 and euthanized 3 days later (n=11; 5 or 6 per each pool); (8) 8 wk old male mice treated with Adeno-CMV and euthanized 3 days later (n=11; 5 or 6 per pool). These RNA pools were used in four separate sets of competitive hybridization experiments: 1) 8 wk untreated M vs. 8 wk untreated F; 2) 8 wk M + Ad-Cux2 (5 day) vs. 8 wk M + Ad-CMV (5 day); 3) 8 wk F + Ad-Cux2 (5 day) vs. 8 wk F + Ad-CMV (5 day); 4) 8 wk M + Ad-Cux2 (3 day) vs. 8 wk M + Ad-CMV (3 day).
