Transcriptional changes in Sohlh1 knockout and Sohlh2 knockout mouse newborn ovaries

ABSTRACT: Sohlh1 and Sohlh2 are germ cell-specific basic helix-loop-helix transcription factors critical in early folliculogenesis. We discovered that Sohlh1 and Sohlh2 knockout females lose oocytes after birth and few remains by postnatal day 14. Here, we show that many genes preferentially expressed in the oocytes are misregulated by Sohlh1 and/or Sohlh2 deficiency.

Transcriptional changes in Sohlh1 knockout and Sohlh2 knockout mouse newborn ovaries

Project description:Sohlh1 and Sohlh2 are germ cell-specific basic helix-loop-helix transcription factors critical in early folliculogenesis. We discovered that Sohlh1 and Sohlh2 knockout females lose oocytes after birth and few remains by postnatal day 14. Here, we show that many genes preferentially expressed in the oocytes are misregulated by Sohlh1 and/or Sohlh2 deficiency. Total RNA samples isolated from wildtype, Sohlh1 KO and Sohlh2 KO mouse newborn ovaries were arrayed on the Illumina BeadChip MouseWG-6 2.0 arrays. We have 4 replicates for wildtype and Sohlh1 KO and 3 replicates for Sohlh2 KO.

Transcriptional changes in Sohlh1/Sohlh2 double knockout newborn mouse ovaries

Project description:Sohlh1 and Sohlh2 are germ cell-specific basic helix-loop-helix transcription factors critical in early folliculogenesis. Differential genes expression by both Sohlh1 and Sohlh2 deficiency in mouse newborn ovaries was accessed using microarray. RNA samples from Sohlh1/ Sohlh2 double knockout and wild-type newborn ovaries were arrayed on the Illumina beadchip mouse WG-6 2.0.

Expression data from testis of day-7 Sohlh1 knock-out mice

Project description:Sohlh1 and Sohlh2 encode a germ cell-specific basic helix-loop-helix transcriptional regulator critical in spermatogonial differentiation. Seven-day-old Sohlh1 or Sohlh2 knockout and wild-type testes were arrayed on the Affy 430 2.0 platform.

FIGLA, LHX8 and SOHLH1 transcription factor networks regulate mouse oocyte growth and differentiation

Project description:Germ-cell transcription factors control gene networks that regulate primordial follicle formation and oocyte differentiation during early, postnatal mouse oogenesis. Taking advantage of gene-edited mice lacking transcription factors expressed in female germ cells, we analyzed global gene expression profiles in perinatal ovaries from wildtype, FiglaNull, Lhx8Null and SohlhNull mice. Figla deficiency dysregulates expression of meiosis-related genes (e.g., Sycp3, Rad51 and Msy2) and a variety of genes (e.g., Nobox, Lhx8, Taf4b, Sohlh1, Sohlh2 and Gdf9) associated with oocyte growth and differentiation. The absence of FIGLA significantly impedes meiotic progression, causes DNA damage and results in oocyte apoptosis. Moreover, we find that FIGLA and other transcriptional regulators (e.g., NOBOX, LHX8, SOHLH1 and SOHLH2) are co-expressed in the same subset of germ cells in perinatal ovaries and Figla ablation dramatically disrupts KIT, NOBOX, LHX8, SOHLH1 and SOHLH2 expression. In addition, not only do FIGLA, SOHLH1 and LHX8 cross-regulate each other, they also cooperate by direct interaction with each during early oocyte development and share downstream gene targets. Thus, our findings substantiate a major role for FIGLA, LHX8 and SOHLH1 as multifunctional regulators of networks necessary for oocyte maintenance and differentiation during early folliculogenesis.

Transcriptional changes in Lhx8 Null newborn mouse ovaries

Project description:Lhx8 is a homeobox gene expressed in oocytes and critical in oogenesis. Lhx8 deficiency leads to rapid loss of postnatal oocytes. Early oocyte differentiation is poorly understood. We hypothesized that lack of Lhx8 perturbs global expression of genes preferentially expressed in oocytes. We compared Lhx8 knockout and wild type ovaries using Affymetrix 430 2.0 microarray platform. Keywords: Genetic Modification

Microarray Analyses of Newborn Mouse Ovaries Lacking Nobox

Project description:Nobox is a homeobox gene expressed in oocytes and critical in oogenesis. Nobox deficiency leads to rapid loss of postnatal oocytes. Early oocyte differentiation is poorly understood. We hypothesized that lack of Nobox perturbs global expression of genes preferentially expressed in oocytes as well as microRNAs. We compared Nobox knockout and wild type ovaries using Affymetrix 430 2.0 microarray platform. We discovered that 28 out of 38 (74%) of the genes down-regulated more than five fold in the absence of Nobox were preferentially expressed in oocytes, while only 5 out of 33 (15%) of genes up-regulated more than five fold in the absence of Nobox, were preferentially expressed in oocytes. Protein binding microarray helped identify nucleotide motifs that NOBOX binds, and that several down-regulated genes contain within putative promoter regions. MicroRNA population in newborn ovaries deficient of Nobox, was largely unaffected. Genes whose proteins are predicted to be secreted, but previously unknown to be significantly expressed in early oogenesis, were down regulated in Nobox knockouts and included astacin-like metalloendopeptidase (Astl), Jagged 1 (Jag1), oocyte secreted protein 1 (Oosp1), fetuin beta (Fetub) and R-spondin 2 (Rspo2). In addition, pluripotency associated genes, Pou5f1 and Sall4 are drastically down-regulated in Nobox deficient ovaries, while testes determining gene Dmrt1 is over-expressed. Our findings indicate that Nobox is likely an activator of oocyte-specific gene expression, and suggest that oocyte plays an important role in suppressing expression of male determining genes such as Dmrt1.
