Comparison of gene expression in wild-type Drosophila testes with tbrd-1 mutant testes

ABSTRACT: Gene expression is tightly linked to histone acetylation on lysine residues that can be recognized by bromodomains. The testis-specific bromodomain protein tBRD-1 is essential for male fertility and might act as a co-factor of testis-specifc TAFs. Here, we perform microarray analyses and demonstrate that tBRD-1 selectively controls gene expression in male germ cells Testes were dissected from 0-2 day old Drosophila males. The wild-type control sample was w1118. The tbrd-1 mutant is described in Leser et al., 2012 (Leser K, Awe S, Barckmann B, Renkawitz-Pohl R, Rathke C. 2012. The bromodomain-containing protein tBRD-1 is specifically expressed in spermatocytes and is essential for male fertility. Biology Open 1: 597-606)

Multicellular organisms have evolved specialized mechanisms to control transcription in a spatial and temporal manner. Gene activation is tightly linked to histone acetylation on lysine residues that can be recognized by bromodomains. Previously, the testis-specifically expressed bromodomain protein tBRD-1 was identified in Drosophila. Expression of tBRD-1 is restricted to highly transcriptionally active primary spermatocytes. tBRD-1 is essential for male fertility and proposed to act as a co-fa ...[more]

RNA-seq of Drosophila melanogaster testis with or without tbrd-1 knock out or tplus3a/b knock out

Project description:Many protein complexes are involved in gene regulation during Drosophila spermatogenesis. tplus3a and tplus3b code for Plus3 domain proteins and are enriched in spermatocytes. Male flies ∆tplus3a/b carrying deletions of both genes in trans to deficiency Df(2L)BSC151 show severely reduced fertility. tbrd-1 is known to regulate hundreds of genes during spermatogenesis in cooperation with tTAFs. To gain more insight into the regulatory mechanisms during spermatogenesis we used RNA from testes of ∆tplus3a/b/Df(2L)BSC151 and tbrd-11 mutant flies for RNAseq in comparison to w1118 wild-typic control. RNA was isolated with Trizol from 200 Testes dissected from w1118, homozygous tbrd-11 mutants or ∆tplus3a/b/Df(2L)BSC151. After DNAse I digestion RNA was purified and RNAseq was performed in three replicates. Genotype Description: w1118: wild-typic control tbrd-11: homozygous tbrd-11 mutants (knock-out through P{EPgy2}tbrd-11, as described in Leser et al., 2012) ∆tplus3a/b/Df(2L)BSC151: CRISPR/Cas9 deletion mutants, representing knock-out of both tplus3 and tplus3b. Male flies y1cho2v1;∆tplus3a/b/CyO were crossed with virgin females w1118;Df(2L)BSC151/CyO. Male offspring with w1118;∆tplus3a/b/Df(2L)BSC151 were used for RNAseq.

Differential protein expression profiles of testes in Tmprss12-/- and wild-type mice

Project description:Serine protease is considered a relative upstream regulator in the physiological processes including male reproduction. Transmembrane serine protease 12 (TMPRSS12) has been shown to regulate sperm motility and uterotubal junction migration in mice, but its role in the testis remains unknown.In this study, we confirmed the important role of TMPRSS12 in spermatogenesis. To further investigate the mechanism of TMPRSS12 in male reproduction, we used 2-D electrophoresis combined with Matrix-assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry(MALDI-TOF/TOF) to construct differential protein expression profiles of testes in Tmprss12-/- and WT mice. A total of 64 spots with 2-fold or more differential expression between two groups were identified using MALDI-TOF/TOF. As a result, 54 unique proteins were identified successfully, including 39 proteins with decreased expression and 15 proteins with increased expression in Tmprss12-/- mice.

mRNA-Seq profiling of Stra8-deficient and wild-type testes

Project description:We sequenced mRNA in grossly enlarged testes from 1-year-old Stra8-deficient mice, and in testes from adult male wild-type controls, to verify that Stra8-deficient testes are enriched for genes normally expressed in type A spermatogonia. Examination of mRNA levels in 6 whole-testis samples (3 replicates of each genotype). Specifically, we sequenced mRNA in grossly enlarged testes from three 1-year-old Stra8-deficient male mice, and in normal testes from three adult male wild-type controls

Transcription profiling of mouse WT and Nxf2 KO post-natal day 21 testes

Project description:In euakryotes, mRNAs must be exported from the nucleus to the cytsoplasm. NXF2 is highly expressed in the mouse male germ cells. We are interested in its function in spermatogenesis, espically in the nuclear RNA export in the testis. To this end, we made Nxf2 mutant mice by gene targeting. In an attempt to identify the mRNA substrates of NXF2, we perform the microarray experiments on testes. We used microarrays to check the expression profiles of the Nxf2 WT and KO 21d testes on C57BL/6 background. Experiment Overall Design: To examine the expression difference between WT and Nxf2 KO testes, we collected testes from juvenile mice of three ages ( 21d, 26d, 28d). Testis weight was similar between WT and KO mice at post-natal day 21. Three pairs of WT and KO 21d testes were chosen for microarray analysis.

Hipk4 is a manchette-associated protein essential for spermiogenesis

Project description:Nonobstructive azoospermia (NOA) is one of the most severe forms of male infertility, characterized by the absence of spermatozoa in the ejaculate. The etiology and genetic mechanism(s) of this disease remain largely unclear. Using Sanger sequence, we identified 12 heterozygous missense mutations and 2 heterozygous nonsense mutations in the HIPK4, encoding a serine/threonine kinase. Moreover, K490* mutant cause HIPK4 unstable in 293T cells. In accord with these findings, we observed that homozygous Hipk4-/- male mice were infertility owing to malformed and immotile spermatozoa, which are characterized by a deformed nucleus and a detached acrosome. Furthermore, we performed a phosphoproteomic analysis of testis from Hipk4 wild type and knockout mice, revealing multiple targets regulated by Hipk4 during spermiogenesis. Notably, manchette-associated protein Rimbp3 has multiple phosphorylation sites regulated by Hipk4. Moreover, Hipk4 and Rimbp3 deficiency mice display several common phenotypes, in particular with regard to the ectopic positioning of the manchette within spermatids, a presumed cause of sperm head deformities. Thus, Hipk4 might regulate manchette function through phosphorylation of Rimbp3, thereby playing essential role for sperm head formation and male fertility.

Transcription profiling of mouse testis at developmental time points

Project description:The overall objective of this proposal is to map the temporal and spatial dynamics of gene expression in the fetal mouse testis at key developmental timepoints. Urogenital tract malformations are the most common birth defects in males and their incidence together with other male reproductive health concerns such as reduced fertility and testicular cancer are reportedly on the rise in the human population. To better understand the impact of genetic factors and environmental influences on testicular development, it is important to first understand normal gene expression patterns and signaling cascades within the fetal testis during development. The goal of this study is to identify cell-specific genes that can be used as biomarkers for key differentiation events.
