CUT&RUN of TAF4b and H3K4me3 in E16.5 oocytes

ABSTRACT: Research has shown that Taf4b-deficient female mice display excessive perinatal germ cell death, delayed germ cell cyst breakdown, and increased chromosome asynapsis. Therefore, we hypothesized that TAF4b, as part of TFIID, regulates oogenesis and meiotic gene programs. However, the direct targets of TAF4b have not been thoroughly explored. Therefore, we performed Cleavage Under Targets and Release Using Nuclease (CUT&RUN) in E16.5 mouse oocytes.

Oocyte transcriptome changes in Taf4b-deficient female mice [E16.5]

Project description:Research has shown that Taf4b-deficient female mice display excessive perinatal germ cell death, delayed germ cell cyst breakdown, and increased chromosome asynapsis. Therefore, we hypothesized that TAF4b, as part of TFIID, regulates oogenesis and meiotic gene programs. However, the transcriptomic effects of Taf4b-deficiency and how this may lead to the infertility we observe in mice has not yet been studied. Therefore, we performed RNA-seq to examine gene expression changes in E16.5 female Taf4b-heterozygous and Taf4b-deficient germ cells

Oocyte transcriptome changes in Taf4b-deficient female mice [E14.5]

Project description:Research has shown that Taf4b-deficient female mice display excessive perinatal germ cell death, delayed germ cell cyst breakdown, and increased chromosome asynapsis. Therefore, we hypothesized that TAF4b, as part of TFIID, regulates oogenesis and meiotic gene programs. However, the transcriptomic effects of Taf4b-deficiency and how this may lead to the infertility we observe in mice has not yet been studied. Therefore, we performed RNA-seq to examine gene expression changes in E14.5 female Taf4b-wildtype, Taf4b-heterozygous, and Taf4b-deficient germ cells

CUT&RUN of TAF4b and H3K4me3 in E16.5 prospermatogonia

Project description:Taf4b-deficient male mice are initially sub-fertile and become infertile due to a depletion of the spermatogonial stem cell (SSC) reserve. During embryonic time points, significantly reduced numbers of germ cells have been observed in the Taf4b-deficient male gonad and previous research has shown that Taf4b mRNA expression peaks at E15.5. Therefore, we hypothesized that TAF4b, as part of TFIID, regulates cell cycle and SSC gene programs. However, the direct targets of TAF4b have not been thoroughly explored. Therefore, we performed Cleavage Under Targets and Release Using Nuclease (CUT&RUN) in E16.5 mouse prospermatogonia.

Functional characterization of Taf4b in Arabidopsis thaliana

Project description:Expression analysis was performed with two TDNA insertion mutants of taf4b i.e; taf4bprm (TDNA insertion in promoter region) and taf4bint (TDNA insertion in intronic region), Taf4b overexpression lines, taf4bprmcpr5 double mutant lines (Double mutant was generated by crossing taf4bprm with cpr5) and Col-0 in normal condition as well as with taf4bprm mutant and Col-0 infected with fungi AB (Alternaria brassicicola) and bacteria ES4 (Pseudomonas syringae pv.maculicola ES4326 ) in different perspectives. Affymatrix expression analysis was executed to provide mechanistic details of regulation of genes by Taf4b in plants.

TBP2/TFIIA complex drives an oocyte-type promoter usage grammar leading to female germ cell specific mRNA and endogenous retroviral element transcription

Project description:The transcriptional machinery involved in RNA polymerase II (Pol II) transcription during oogenesis is not well characterized. In somatic cells, the Pol II general transcription factor, TFIID, containing the TATA binding protein (TBP) and 13 TBP-associated factors, is the first to bind gene promoters to nucleate pre-initiation complex formation. During oocyte growth TBP is replaced by TBP2 and Tbp2-/- female mice are sterile. Here, we show that in oocytes TBP2 stably associates with TFIIA but does not assemble into a TFIID-type complex but stabily associates with TFIIA. we demonstrate that in female germ cells the specific TBP2-TFIIA-containing transcription machinery drives transcription from oocyte-specific core promoters, which are different from those occupied by TBP/TFIID in somatic cells.

Gene expression differences between TAF4b-KO, Het and WT ovaries at 3 weeks of age

Project description:The rapid decline of ovarian function in TAF4b-null mice begins in early postnatal life and follicle depletion is completed by sixteen weeks. To uncover differences in gene expression that may underlie accelerated ovarian aging, we compared genome-wide expression profiles of three week old, pre-pubescent TAF4b-null and wild-type ovaries. Total RNA from 9, 3-week-old mice (3 wild-type, 3 TAF4b-heterozygous, 3 TAF4b-null) was obtained as described as above. RNA quality was checked using a Bioanalyzer, and concentration determined using a Nanodrop. 300 ng of each RNA sample was used in the Affymetrix Whole-transcript Sense Target Labeling Assay (Rev 3) followed by hybridization to a GeneChipÂ® Mouse Gene 1.0 ST Array. 9 GeneChips were used to provide biological triplicates of each genotype. The Affymetrix Expression Console (v 1.1) was used to normalize data and determine signal intensity (RMA-Sketch).
