Comparative Analysis of Macaque and Human Sperm Proteomes: Insights into Sperm Competition

Abstract

Male macaques produce faster sperm than male humans due to a higher pressure of sperm competition in macaques. To explore the molecular basis of this biological difference, we firstly constructed macaque and human sperm proteomes using liquid chromatography-tandem mass spectrometry. We then detected the positively selected genes specifically on the branch of macaque based on branch-site likelihood method. We identified 197 positively selected genes specifically on the branch of macaque which are unselected in corresponding human orthologs. These genes are highly associated with mitochondria and axoneme which directly drive sperm motility. We further compared the ultrastructural differences of the mid-piece between macaque and human sperms to provide evidence for our findings using transmission electron microscopy. In conclusion, our results provide potential molecular targets for explaining the different phenotypes under sperm competition between macaques and humans, and also provide resources for the analysis of male fertility.

Proteomic analysis of N-glycosylation of human seminal plasma

Abstract

Seminal plasma is a mixture of secretions from several male accessory glands. The seminal plasma contains many secreted proteins which are important for sperm function and male fertility. In this study, we employed N-linked glycosylated peptide enrichment, combined with LC-MS/MS analysis, and establish the first large scale N-linked glycoproteome of human seminal plasma. Combined with the results of five biological replicates, a total of 720 N-glycosylated sites on 372 proteins were identified. Analysis of variations among five individuals revealed similar compositions of N-glycosylated proteins in seminal plasma. The N-linked glycoproteome could help us understanding the biological functions of human seminal plasma. The data set could also be a resource for further screening of biomarkers for male diseases including cancer and infertility at the level of N-glycosylation. For example, N-glycosylated prostate-specific antigen is known to be an efficient biomarker that can distinguish benign prostate hyperplasia from prostate cancer.

Abstract

Recently, emerging evidence has shown that Stat3 controls tumor cell migration and invasion. However, the molecular mechanisms by which Stat3 controls the cell movement remain largely unknown. Embryonic gastrula progenitors display coordinated and orientated migration, called collective cell migration. Collective cell migration is the simultaneous movement of multiple cells and is universally involved in physiological and pathological programs. Stat3 activity is required for the migration of gastrula progenitors, but it does not affect cell specification, thus suggesting that gastrula movements are an excellent model to provide insight into Stat3 control of cell migration in vivo. In this study, we reveal a novel mechanism by which Stat3 modulates extracellular matrix (ECM) assembly to control the coherence of collective migration of prechordal plate progenitors during zebrafish embryonic gastrulation. We show that Stat3 regulates the expression of Efemp2a in the prechordal plate progenitors that migrate anteriorly during gastrulation. Alteration of Stat3-Efemp2a signaling activity disrupted the configuration of fibronectin (FN) and laminin (LM) matrices, resulting in defective coherence of prechordal plate progenitor movements in zebrafish embryos. We demonstrate that Efemp2a acts as a downstream effector of Stat3 to promote ECM configuration for coherent collective cell migrations in vivo. © 2014. Published by The Company of Biologists Ltd.

Stem cell science on the rise in China

Cell Stem Cell. 2012 Jan 6;10(1):12-5. doi: 10.1016/j.stem.2011.12.002.

Abstract

China's output in fundamental stem cell research has increased markedly in recent years. Vigorous public investment and infrastructure development have enabled major productivity gains, but challenges in regulation, governance, and the management of clinical expectations must be addressed to ensure scientific quality and sustainable growth.
