<h4>Background</h4>Partial loss of function of the transcription factor FOXL2 leads to premature ovarian failure in women. In animal models, Foxl2 is required for maintenance, and possibly induction, of female sex determination independently of other critical genes, e.g., Rspo1. Here we report expression profiling of mouse ovaries that lack Foxl2 alone or in combination with Wnt4 or Kit/c-Kit.<h4>Results</h4>Following Foxl2 loss, early testis genes (including Inhbb, Dhh, and Sox9) and several no ...[more]

Foxl2 functions in sex determination and histogenesis throughout mouse ovary development, analyzed by Agilent arrays

Project description:Partial loss of function of the transcription factor FOXL2 leads to premature ovarian failure in women. In animal models, Foxl2 is required for maintenance, and possibly induction, of female sex determination independently of other critical genes, i.e., Rspo1 and Wnt4. Here we report expression profiling of mouse ovaries that lack Foxl2 alone or in combination with Wnt4 or Kit/c-Kit, to identify ovarian targets of Foxl2 that, along with some testis genes, were dysregulated during embryonic development. Loss of one copy of Foxl2 revealed strong gene dosage sensitivity, with molecular anomalies that were milder but resembled ovaries lacking both Foxl2 alleles. Furthermore, a Foxl2 transgene disrupted embryonic testis differentiation and increased the levels of key female markers. The results, including a comprehensive principal component analysis of published microarray datasets 1) support the proposal of dose-dependent Foxl2 function and anti-testis action throughout ovary differentiation; and 2) identify candidate genes for a role in sex determination independent of FOXL2 (notably, the transcription factor, ZBTB7C) and in the generation of the ovarian reserve downstream of it (e.g., the cadherin-domain protein CLSTN2, or the sphingomyelin synthase, SGMS2). The gene inventory provides a framework to analyze the genetic bases of ovarian development and female fertility.

FOXL2 interaction with different binding partners regulates the dynamics of granulosa cell differentiation across ovarian development

Project description:FOXL2 is a transcription factor essential for female fertility, expressed in somatic cells of the ovary, notably granulosa cells. In the mouse, Foxl2 deletion leads to partial sex reversal postnatally. However, deletion of the gene in 8-week-old females leads to granulosa to Sertoli cell transdifferentiation. We hypothesised that different outcomes of Foxl2 deletion in embryonic versus adult ovary may depend on a different role played across ovarian development. Therefore, we characterised the dynamics of gene expression and chromatin accessibility changes in purified murine granulosa cells across key developmental stages (E14.5, 1 and 8 weeks). We then performed genome-wide identification of FOXL2 target genes and on-chromatin interacting partners by ChIP-SICAP. We found that FOXL2 regulates more genes at postnatal stages, through the interaction with factors regulating primordial follicle activation (PFA), such as NR5A2, and others regulating steroidogenesis including AR and ESR2. As a proof of principle experiment, we chose one FOXL2 interactor, Ubiquitin specific protease 7 (USP7) and showed that deletion of this gene in granulosa cells leads to a blockage of PFA, impaired ovary development and sterility. Our study constitutes a comprehensive resource for exploration of the molecular mechanisms of ovarian development and causes of female infertility.

Transcription profiling of mouse KK1 granulosa cells transfected with Foxl2-VP16 and Foxl2-MAD

Project description:The Foxl2 transcription factor is required for ovarian function during follicular development. Our approach to begin to understand Foxl2 function is through the identification of Foxl2 regulated genes in the ovary. Transiently transfected KK1 mouse granulosa cells were used to identify genes that are potentially regulated by Foxl2. KK1 cells were transfected in three groups (mock, activated, and repressed) and twenty-four hours later RNA was isolated and submitted for Affymetrix microarray analysis. Experiment Overall Design: To increase the potential of Foxl2 to alter gene expression levels of putative target genes, two fusions were constructed consisting of Foxl2 fused to the activation domain of the Herpes simplex virus VP16 transcription factor (Foxl2-VP16) and Foxl2 fused to the repression domain of the murine MAD transcription factor (Foxl2-MAD). Levels of gene expression were compared between mock transfected cells and those that were transfected with Foxl2-VP16 and Foxl2-MAD, respectively.

BAF250B-associated SWI/SNF chromatin-remodeling complex is required to maintain undifferentiated mouse ES cells

Project description:We used BAF250b-/- ES cells, two independently derived clones, at 18 and 72 hr in culture and compared them with parental cell line (wild-type) at the same time in culture (two replications each). Total RNAs were extracted using Trizol (Invitrogen) according to manufacturer protocol. 2.5 ug of total RNA samples were labeled with Cy3-CTP using a Low RNA Input Fluorescent Linear Amplification Kit (Agilent). A reference target (Cy5-CTP-labeled) was prepared from the Universal Mouse Reference RNA (Stratagene). Labeled targets were purified using an RNeasy Mini Kit (Qiagen) according to the Agilent's protocol, quantitated by a NanoDrop scanning spectrophotometer (NanoDrop Technologies), and hybridized to the NIA Mouse 44K Microarray v2.2 (whole genome 60-mer oligo; manufactured by Agilent Technologies, #014117) (Carter et al. 2005) according to the Agilent protocol (G4140-90030; Agilent 60-mer oligo microarray processing protocol - SSC Wash, v1.0). All hybridizations were carried out in the two color protocol by combining one Cy3-CTP-labeled experimental target and Cy5-CTP-labeled reference target. Microarrays were scanned on an Agilent DNA Microarray Scanner, using standard settings, including automatic PMT adjustment. Keywords: genetic modification design,time series design Biological replications were performed on BAF250b-/- ES cells with their parental line (wild-type) at 18 and 72 hrs after passaging, as well as with 12 other pluripotent cells (ES and EG cells from strains C57BL/6 and 129 data from Sharova et al., 2007) using whole-genome mouse microarrays (NIA 44k V2.2 with 60-mer synthesized oligos).

Identification of protein co-localized with Foxl2 on chromatin

Project description:Foxl2 is a forkhead transcription factor essential for proper reproductive function in females. It is expressed in the somatic cell population of the gonad (granulosa cells) which forms the follicles of the ovary, the structures responsible for embedding and nurturing the oocytes during their development. FOXL2 directly regulate the aromatase that synthesizes estrogens CYP19A1, thus promoting female differentiation, as well as acting as a repressor of the male factors SOX9 and DMRT1.Expression is also found in the eyelids, pituitary gland and uterus. In the goat, frog and many fish species FOXL2 is a sex-determining gene which, when deleted, leads to female-to-male sex reversal.

Gene knockdown and overexpression of 402C>G FOXL2 in COV434 and KGN cells

Project description:Despite their distinct biology, granulosa cell tumours (GCTs) are treated the same as other ovarian tumours. Intriguingly, a recurring somatic mutation in the transcription factor Forkhead Box L2 (FOXL2) 402C>G has been found in nearly all GCTs examined. This investigation aims to identify the pathogenicity of mutant FOXL2 by studying its altered transcriptional targets. The expression of mutant FOXL2 was reduced in the GCT cell line KGN, and wildtype and mutant FOXL2 were overexpressed in the GCT cell line COV434. Comparisons were made between the transcriptomes of control cells and cells altered by FOXL2 knockdown and overexpression, to detect potential transcriptional targets of mutant FOXL2. Comparisons were made between the transcriptomes of control cells and cells altered by FOXL2 knockdown and overexpression, to detect potential transcriptional targets of mutant FOXL2. Mutant FOXL2 was silenced in KGN cells with the use of siRNA and a non-targetting siRNA control. Wildtype and mutant FOXL2 were overexpressed in COV434 cells with the use of overexpression plasmids and an empty plasmid control. Each experiment was performed in triplicate. Total RNA was harvested at 24h post transfection and hybridised to Affymetrix U133 plus 2.0 arrays.
