MetabolomicsNGT induced mitochondrial dysfunction, led to apoptosis, and changed metabolites associated with oxidized lipids in sperm of Pacific oyster (Crassostrea gigas).

The risk of norgestrel (NGT) exposure in the aquatic environment has been identified, but the toxic effects on invertebrate germ cells are unknown. Therefore, the toxic effects of NGT on oyster sperm were investigated by combining transcriptome and metabolome analysis with histology. Transcriptom...

TranscriptomicsStallion sperm transcriptome as revealed by microarray analysis and RNA sequencing
Purpose: In order to understand the functional significance of sperm transcriptome in stallion fertility, the aim of this study was to generate a detailed body of knowledge about the sperm RNA profile that defines a normal fertile stallion. Methods: The 50 bp single-end ABI SOLiD raw reads were dire...

TranscriptomicsA Restricted Role for Sperm-borne MicroRNAs in Mammalian Fertilization
Prototypical micro RNAs (miRNAs) are 21~25-base-pair RNAs that regulate differentiation, carcinogenesis and pluripotency by eliminating mRNAs or blocking their translation, processes collectively termed RNA interference (RNAi). RNAi mediated by miRNAs regulates early development in zebrafish, and mo...

TranscriptomicsThe Partitioning of RNAs in sperm
A diverse pool of RNAs remain encapsulated within the transcriptionally and translationally silent spermatozoon. These transcripts persist within the male gamete despite the dramatic reduction in cellular volume achieved through expulsion of the cytoplasm and quite possibly the nucleoplasm. The prec...

GenomicsDistinctive Chromatin in Human Sperm Packages Genes that Guide Embryo Development: ChIP-seq
As nucleosomes are widely replaced by protamine in mature human sperm, epigenetic contributions to embryo development appear limited. However, our genome-wide approaches find nucleosomes at low levels genome-wide, but also significantly enriched at imprinted gene clusters, miRNA clusters, HOX gene...

ProteomicsCrocodile Sperm Proteome
In a reproductive strategy that is considered unique to the mammalian lineage, spermatozoa must undergo a series of physiological changes, termed capacitation, in the female reproductive tract prior to developing their capacity to fertilize an ovum. Here, we have employed a comparative proteomic str...

TranscriptomicsSperm RNA: A window to idiopathic infertile couples
We examine how NGS sequencing of sperm can provide a window as to how particular perturbations of the sperm RNA profile from baseline may be indicative of male factor infertility, and may thus provide direction as to proper course of infertility treatment for couple. NGS RNA-seq of 72 sperm samples ...

TranscriptomicsBroad, ectopic expression of the sperm protein, PLCZ1 induces parthenogenesis and ovarian tumours in mice
Mammalian metaphase II (mII) exit and embryogenesis are induced at fertilization by a signal thought to come from the sperm protein, phospholipase C-zeta (PLCZ1). Meiotic progression can also be triggered without sperm, as in parthenogenesis, although the classic mouse in vivo parthenogenetic model...

ProteomicsProteomic analysis of dimorphic sperm in the Cabbage White Butterfly, Pieris rapae
Sperm dimorphism, the production of two distinct sperm morphs by a single male, is a widespread but poorly understood reproductive phenomenon. In Lepidoptera, fertilizing eupyrene sperm coexist with anucleate apyrene sperm, which cannot fertilize eggs but are nevertheless required for successful rep...

ProteomicsIdentification of key genes related to sperm freezability in Holstein bulls using proteomics and association analysis
We compared protein profiles of sperm cells in the high sperm freezability group and the low sperm freezability group of Holstein bulls to identify the important proteins and their mechanisms that affect sperm freezability.
