Project description:Here we show that the Drosophila nuclear receptor DHR39 is necessary for male reproduction and acts as a global regulator of accessory gland gene expression. Mutants for the DHR39 transcription factor are sterile, with the majority of accessory gland genes expressed at reduced levels. Specific depletion of DHR39 within the accessory gland is sufficient to reduce male fecundity and accessory gland gene expression. Restoration of DHR39 in the accessory gland of DHR39 mutants rescues this sterility and transcriptional reduction. We conclude that DHR39 is a key regulator of most accessory gland genes, including ovulin and sex peptide, and is necessary for male fertility.

Project description:The accessory gland (AG), an important component of the male reproductive system, enhances the fertility of spermatozoa during male reproduction. Some AG proteins are known to bind to the spermatozoa membrane and affect its function and properties. In this study, we describe, for the first time, a comprehensive catalog of proteins of the AG secreted fluid during the mature phase of the Chinese mitten crab (Eriocheir sinensis). AG secreted proteins were separated by one-dimensional gel electrophoresis and analyzed by reverse phase high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS).

Project description:The Drosophila melanogaster male accessory gland (AG) is crucial for reproductive success, producing seminal fluid proteins that impact female post-mating behavior and physiology. To understand the regulatory networks governing accessory gland function, we conducted a bulk RNA sequencing (RNA-Seq) study to analyze the effects of overexpressing three key regulatory genes: dMyc, Yorkie (Yki), and the E2F-Dp heterodimer, compared to wild-type (WT) controls. We found upregulated and downregulated genes in each condition compared to controls, affecting immune response, cell cycle, stress response, and reproductive functions. In both Yki constitutively active, E2F+Dp and dMyc, E2F+DP conditions, several genes known to be involved in wound healing and tumorigenic models in flies were upregulated, including JNK signaling targets Ets21C, MMP1, puckered, and Jak/STAT signaling pathway ligands upd2 and upd3. Conversely, accessory gland-specific genes, such as many Accessory Gland Proteins (Acps), and genes involved in fertility, mating behavior, and sperm competition were downregulated. There was a strong overlap between the Yki constitutively active, E2F+Dp and dMyc, E2F+Dp gene expression signatures, converging on genes commonly misregulated in proliferative tumor models in various larval tissues, including imaginal discs and brains. This study provides insights into the molecular mechanisms by which key regulatory genes influence the function and integrity of the Drosophila male accessory gland.

Project description:In insects, male accessory gland proteins (ACPs) are important reproductive proteins secreted by male accessory glands (MAGs) of the internal male reproductive system. During mating, ACPs were transferred along with sperms inside female bodies and have a significant impact on the physiology of female reproduction. Under sexual selection pressures, the ACPs exhibit remarkably rapid and divergent evolution and varies from species to species. The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is a major insect pest of cruciferous vegetables worldwide. The reproductive physiology on post-mating state of this species is still largely unknown, which is important for management of this pest. In this study, the ACPs transferred into females during mating were identified by using a tandem mass tags quantitative proteomic analysis. The MAGs were compared before and after mating immediately. In total, we identified 123 putative secreted ACPs, including most important physiological: regulators of proteolysis, transporters and protein export machinery, signal transduction and immunity. Comparing P. xylostella with other four insect ACPs, trypsins were the only ACPs detected in all insect species. This was the first time to identify and analyze ACPs in P. xylostella. Our results have provided an important list of putative secreted ACPs, and have set the stage for further explore functions of these putative proteins in P. xylostella reproduction.

The proteomes of copulatory bursas (CB) in mated females shortly after mating were also analyzed by shotgun LC-MS/MS technique. In total, we identified 123 putative secreted ACPs, including most important physiological: regulators of proteolysis, transporters and protein export machinery, signal transduction and immunity. Comparing P. xylostella with other four insect ACPs, trypsins were the only ACPs detected in all insect species. We also identified some new insect ACPs, including protein with chitin binding Peritrophin-A domain, PMP-22/EMP/MP20/Claudin tight junction domain-containing protein, netrin-1, type II inositol 1,4,5-trisphosphate 5-phosphatase, two spaetzles, allatostatin-CC and cuticular protein. This was the first time to identify and analyze ACPs in P. xylostella. Our results have provided an important list of putative secreted ACPs, and have set the stage for further explore functions of these putative proteins in P. xylostella reproduction.

Project description:In Drosophila, the accessory gland proteins (Acps) secreted from the male accessory glands (MAGs) and transferred along with sperm into the female reproductive tract have been implicated in triggering postmating behavioral changes, including refractoriness to subsequent mating and propensity to egg laying. Recently, Acps have been found also in Anopheles, suggesting similar functions. Understanding the mechanisms underlying transcriptional regulation of Acps and their functional role in modulating Anopheles postmating behavior may lead to the identification of novel vector control strategies to reduce mosquito populations. We identified heat-shock factor (HSF) binding sites within the Acp promoters of male Anopheles gambiae and discovered three distinct Hsf isoforms; one being significantly up-regulated in the MAGs after mating. Through genome-wide transcription analysis of Hsf-silenced males, we observed significant down-regulation in 50% of the Acp genes if compared to control males treated with a construct directed against an unrelated bacterial sequence. Treated males retained normal life span and reproductive behavior compared to control males. However, mated wild-type females showed a ∼46% reduction of egg deposition rate and a ∼23% reduction of hatching rate (∼58% combined reduction of progeny). Our results highlight an unsuspected role of HSF in regulating Acp transcription in A. gambiae and provide evidence that Acp down-regulation in males leads a significant reduction of progeny, thus opening new avenues toward the development of novel vector control strategies.

Treated males retained normal life span and reproductive behavior compared to control males. However, mated wild-type females showed a ?46% reduction of egg deposition rate and a ?23% reduction of hatching rate (?58% combined reduction of progeny). Our results highlight an unsuspected role of HSF in regulating Acp transcription in A. gambiae and provide evidence that Acp down-regulation in males leads a significant reduction of progeny, thus opening new avenues toward the development of novel vector control strategies. Total RNA from 4-d-old dsLacZ-treated controls and HSF-silenced males was extracted using TRIzol reagent (Life Technologies), following protocols set according to manufacturer’s instructions. RNA preparation, labelling, hybridization and data analysis were performed by the Oxford Gene Technology (OGT) company. In particular, RNA was further cleaned up using the RNeasy Mini Kit (Qiagen) followed by ethanol precipitation. Sample passing the purity metrics (260/280 and 260/230 ratio) were considered for labeling and hybridization procedures. Labeling was done with cyanine 3 (dsHSF1 and dsHSF123) and cyanine 5 (control dsLacZ). Samples and controls were hybridized in triplicates to the Agilent Mosquito Gene expression arrays (4x44,000, Agilent Technologies, Santa Clara, CA, USA). Data analysis was performed by OGT according to a standardized procedure, as implemented by the software applications Feature Extraction (version 9.5.3.1.), and Genespring GX (version 11.0). Expression data was first normalised using linear and loess normalization in Feature Extraction, then it was imported into Genespring where it was converted into normalised log ratios. The distribution of the data between and within the treatments was checked via boxplots and hierarchical clustering to confirm consistency. Intensity measures from spots flagged as being of poor quality were excluded. Then, the control probes were removed for the statistical analysis: t-tests were carried out for each condition with null hypothesis of log ratio being equal to zero. This was done on the normalised log ratios from the 3 technical replicates. Probes meeting a cut-off of p<0.05 with Benjamini-Hochberg multiple testing correction and with a fold change cutoff greater than 2 were considered statistically and biologically relevant and were used to generate lists of differentially expressed targets.
