Grapholita molesta is a globally significant fruit pest. Females achieve maximal reproductive output through efficient sperm utilization following a single copulation. Post-mating maturation of eupyrene sperm is a critical step in reproductive success. Here, we report that a male accessory gland-derived serine protease (named GmAGSP1) is essential for this process. GmAGSP1 was only distantly related to other identified sperm-activating SPs, and its transcript was highly expressed in the A ...[more]

Characterization of human pineal gland proteome

Project description:Pineal gland is a neuroendocrine gland located at the center of the brain. It protects the body from the effect of toxic compounds and regulates sleep-wake cycle, body temperature and sexual maturity through the secretion of melatonin. Abnormal functioning of pineal glands is known to be associated with Smith-Magenis syndrome, autism spectrum disorder, sleep disorders and Alzheimer’s disease. Characterization of pineal gland proteome will facilitate molecular level investigations on pathophysiological conditions underlying these diseases. We aimed to characterize the proteome of human pineal glands using a high resolution mass spectrometry- based approach. A total of 5,752 proteins were identified from human pineal glands in this study. Of these, 1,108 proteins contained signal peptide domain. We identified 2 novel proteins in this study, which are predicted by computational methods. In addition, a large number of proteins were uniquely identified in this study. A comprehensive list of proteins identified from human pineal glands will aid in unraveling the role of pineal glands in sleep disorders, neuropsychiatric and neurodegenerative diseases.

Proteome analysis of male accessory gland secretions in the diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae)

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.

Proteomic analysis of human anterior pituitary gland

Project description:The regulation of pituitary function via the hypothalamus and via intra-pituitary connections represents a complex system. Though hormones secreted from the pituitary glands have been well studied, overall information of proteins expressed in the pituitary glands is very limited. Protein expression profiling of normal pituitary tissue may lead to discovery of novel proteins playing an important role in the physiology of pituitary glands and can lead to better understanding of pituitary gland diseases. We aimed to carry out systematic proteomic profiling of adenohypophysis from human pituitary glands using high-resolution Fourier transform mass spectrometer. A total of 2,175 proteins were identified in this study of which, 105 proteins were identified for the first time as compared to high throughput proteomic-based studies from human pituitary glands. The comprehensive list of proteins identified in this study will facilitate the better understanding the role of this important gland in health and disease.

Human Lacrimal Gland Gene Expression

Project description:Background: The study of human lacrimal gland biology and development is limited. Lacrimal gland tissue is damaged or poorly functional in a number of disease states including dry eye disease. Development of cell based therapies for lacrimal gland diseases requires a better understanding of the gene expression and signaling pathways in lacrimal gland. Differential gene expression analysis between lacrimal gland and other embryologically similar tissues may be helpful in furthering our understanding of lacrimal gland development. Methods: We performed global gene expression analysis of human lacrimal gland tissue using Affymetrix ® gene expression arrays. Primary data from our laboratory was compared with datasets available in the NLM GEO database for other surface ectodermal tissues including salivary gland, skin, conjunctiva and corneal epithelium. Results: The analysis revealed statistically significant difference in the gene expression of lacrimal gland tissue compared to other ectodermal tissues. The lacrimal gland specific, cell surface secretory protein encoding genes and critical signaling pathways which distinguish lacrimal gland from other ectodermal tissues are described. Conclusions: Differential gene expression in human lacrimal gland compared with other ectodermal tissue types revealed interesting patterns which may serve as the basis for future studies in directed differentiation among other areas.

Proteome Analysis of Male Accessory Gland Secretions in the Diamondback Moth, Plutella xylostella (Lepidoptera: Plutellidae).

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 are transferred along with sperms inside female bodies and have a significant impact on the post-mating physiology changes of the females. Under sexual selection pressures, the ACPs exhibit remarkably rapid and divergent evolution and vary from species to species. The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is a major insect pest of cruciferous vegetables worldwide. Mating has a profound impact on the females' behavior and physiology in this species. It is still unclear what the ACPs are in this species. In this study, two different proteomic methods were used to identify ACPs in P. xylostella. The proteins of MAGs were compared immediately before and after mating by using a tandem mass tags (TMT) quantitative proteomic analysis. The proteomes of copulatory bursas (CB) in mated females shortly after mating were also analyzed by the shotgun LC-MS/MS technique. In total, we identified 123 putative secreted ACPs. 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 proteins 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 is the first time that ACPs have been identified and analyzed in P. xylostella. Our results have provided an important list of putative secreted ACPs, and have set the stage for further exploration of the functions of these putative proteins in P. xylostella reproduction.
