Sex-dependent and STAT5a-dependent Liver Gene Expression

ABSTRACT: A series of dual-channel gene expression profiles obtained using Agilent Mouse TOE 75k microarrays was used to examine the sex-dependent and STAT5a-dependent differences in gene expression in adult mouse liver. This series is comprised of 3 randomly chosen independent male and female wildtype mouse liver cDNA samples and 3 randomly chosen independent male and female STAT5a-deficient mouse liver cDNA samples, totalling 12 samples. The samples were paired randomly to generate 4 comparisons of M-WT:F-WT, M-WT:M-KO, F-KO:F-WT, F-KO:M-KO. Comparison of the set of sex-dependent genes with the set of genes responsive to the loss of STAT5a in females shows a small group of the sex-specific genes were also regulated by STAT5a in females. These results indicate a role for STAT5a in female gene expression to a lesser degree than that shown for STAT5b in males. Keywords: genetic knockout and sex response

Sex-dependent and STAT5b-dependent Liver Gene Expression

Project description:A series of dual-channel gene expression profiles obtained using Rosetta/Merck Mouse TOE 75k microarrays was used to examine the sex-dependent and STAT5b-dependent differences in gene expression in adult mouse liver. This series is comprised of 4 pools of 3 randomly chosen independent wildtype male and female mouse liver cDNA samples and 4 pools of 3 randomly chosen independent STAT5b-deficient male and female mouse liver cDNA samples, totaling 16 pools. The pools were paired randomly to generate 4 comparisons of M-WT:F-WT, M-WT:M-KO, F-KO:F-WT, and F-KO:M-KO. Comparison of the set of sex-dependent genes with the set of genes responsive to the loss of STAT5b in males shows that 75% of the sex-specific genes were also regulated by STAT5b in males. Only 20% of the sex-specific genes retained sex-specificity in the absence of STAT5b, indicating a large role for STAT5b in sex-specific liver gene expression. A pool of cDNA from 3 mice is Cy3-labeled and compared to another pool of cDNA from 3 mice that is Cy5-labeled. The pools are then dye-swapped and compared again. The two pairs of data are averaged together, the averages are normalized across the fluorescent reverse pairings, and the log2 value is reported for each average as well as the anti-log. This is replicated 3 times with independent pools of cDNA for each pair of conditions being compared. There are a total of 4 pairs of conditions compared for a grand total of 12 samples.

Sex-dependent and strain-dependent gene liver gene expression

Project description:A series of dual-channel gene expression profiles obtained using Agilent Mouse TOE 75k microarrays was used to examine the sex-dependent differences in gene expression across three outbred mouse strains, 129J x Black Swiss, 129J x BALB/c, and ICR. This series is comprised of samples obtained from 3 pools of randomly chosen independent cDNA samples of male and female 129Jx BALB/c mice and 3 randomly chosen independent cDNA samples of male and female 129J x Black Swiss mice and 5 randomly chosen independent cDNA samples of male and female ICR mice. The ICR mice were randomly distributed into three and two member pools for each sex and two of the 5 samples for each sex were independently hybridized separately as well. Comparison of the sex-specific genes for the three outbred strains generated lists of strain-dependent and strain-independent sex-specific genes. Keywords: sex response and strain response

Transcription profiling of mouse adult male wild-type liver (M-WT), adult female wild-type liver (F-WT), adult male liver-specific HNF4alpha knockout liver (M-KO) and adult female liver-specific HNF4alpha knockout liver (F-KO) to investigate sex-dependent and HNF4alpha-dependent gene expression

Project description:A series of dual-channel gene expression profiles obtained using Rosetta/Agilent Whole Mouse Genome oligonucleotide microarrays, 4 x 44K format, was used to identify sex-dependent and HNF4alpha-dependent differences in gene expression in adult mouse liver. This series is comprised of four sex-genotype combinations: adult male wild-type liver (M-WT), adult female wild-type liver (F-WT), adult male liver-specific HNF4alpha knockout liver (M-KO) and adult female liver-specific HNF4alpha knockout liver (F-KO). Four pools, each comprised of 4 randomly selected individual liver RNAs, were prepared for each sex-genotype combination. The pools were paired randomly to generate 4 separate experimental comparisons: M-WT:F-WT (first array comparison), M-WT:M-KO (second array comparison), F-WT:F-KO (third array comparison), and M-KO:F-KO (fourth array comparison). A total of 4994 HNF4alpha-dependent genes were identified, of which ~1000 fewer genes responded to the loss of HNF4alpha in female liver as compared to male liver. Moreover, 90% of the genes showing sex-specific expression in the liver were shown to lose sex specificity in HNF4alpha-deficient liver. Experiment Overall Design: An Alexa555-labeled cDNA sample is co-hybridized with an Alexa647-labeled cDNA sample. The samples are then dye-swapped and compared again on a second microarray chip. Together, these two mixed cDNA samples are considered a fluorescent reverse pair (dye swap). Similarly, a second fluorescent reverse pair is generated and the two pairs are averaged. The normalized expression ratio for each array is reported along with the two separate intensities. In this way, dye swaps were carried out for each of the four experimental comparisons. Thus, four microarrays, one for each mixed cDNA sample, were hybridized for each of the four fluorescent reverse pairs, giving a total of 16 microarrays.

Sex-dependent and growth hormone (GH)-dependent gene expression

Project description:A series of dual-channel gene expression profiles obtained using MWG Rat 5K microarrays (~5535 unique rat genes) and MWG Rat Liver microarrays (~1353 unique rat genes with 999 of these genes also represented on the Rat 5K microarray) was used to examine the sex-dependent and GH-dependent differences in gene expression in adult rat liver. This series is comprised of 8 randomly chosen pairings of independent male and female rat liver cDNA samples and 8 randomly chosen pairings of independent male and continuous GH-treated male rat liver cDNA samples, totaling 16 samples. Half of the samples were hybridized to the MWG Rat 5K microarrays and the other half were hybridized to the MWG Rat Liver microarrays. Comparison of the set of sex-dependent genes with the set of GH-responsive genes shows that 90% of male-dominant genes are suppressed in male rats treated with a female pattern of GH. Approximately 73% of female-dominant genes were up-regulated in the continuous GH-treated male rats. Keywords = Growth hormone Keywords = liver sexual dimorphism Keywords = cytochrome P450 Keywords = liver gene expression Keywords = dual channel cDNA microarray Keywords: repeat sample

Gene expression profiling of mouse liver with hepatocyte-specific knockout of STAT5a/STAT5b genes (STAT5ab-KO)

Project description:rRNA-depleted RNA isolated from livers of control male and female mice and from male mice with hepatocyte-specific STAT5ab-KO was analyzed by RNA-seq. This study revealed a substantial, albeit incomplete loss of liver sex bias in hepatocyte-specific STAT5a/STAT5b (collectively, STAT5)-deficient mouse liver. Notably, in male liver, many male-biased genes were down regulated in direct association with the loss of STAT5 binding; many female-biased genes, which show low STAT5 binding, were de-repressed, indicating an indirect mechanism for repression by STAT5.

RRBS (reduced representation bisulfite sequencing) analysis of hepatocyte-specific STAT5a/STAT5b Knockout (STAT5ab-KO) mouse liver to identify differentially methylated regions (DMRs)

Project description:The impact of STAT5 on liver DNA methylation was assessed by performing RRBS analysis on male and female mouse liver with a hepatocyte-specific loss of STAT5a and STAT5b. Extensive changes in CpG-methylation were seen in STAT5-deficient liver, where sex differences were abolished at 88% of ~1,500 sex-differentially methylated regions, largely due to increased DNA methylation upon STAT5 loss. STAT5-dependent CpG-hypomethylation was rarely found at proximal promoters of STAT5-dependent genes. Rather, STAT5 primarily regulated the methylation of distal enhancers, where STAT5 deficiency induced widespread hypermethylation at genomic regions enriched for accessible chromatin, enhancer histone marks (H3K4me1, H3K27ac), STAT5 binding, and DNA motifs for STAT5 and other transcription factors implicated in liver sex differences. Thus, the sex-dependent binding of STAT5 to liver chromatin is closely linked to the sex-dependent demethylation of distal regulatory elements linked to STAT5-dependent genes important for liver sex bias.

Liver transcriptome analysis comparing gene expression between Esr1 knockout mice and wild type littermates

Project description:The overall purpose of the study is to understand the origin of the different DNA methylation patterns in mice with different sex phenotypes. Specifically, we look at the roles of three factors associated with sex hormone signaling, including estrogen receptor alpha (ESR1), during development in mouse liver. In order to do that, we compare the transcriptomes of male and female B6N(Cg)-Esr1^tm4.2Ksk/J mice (ESR1 KO) mice and wild type (WT) control littermates, and identify differentially expressed genes. Those genes will then be compared to the differential methylation data obtained using pyrosequenceing.
