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...

MetabolomicsTEX44 CPT1B Axis Regulates Mitochondrial Sheath Assembly and Fatty Acid Oxidation in Sperm
Mitochondrial fatty acid β-oxidation (FAO) is essential for energy production and cellular homeostasis, yet its specific role in sperm function has remained unclear. Through whole-exome sequencing of 673 patients with asthenozoospermia, we identified biallelic TEX44 variants in six individuals, all ...

Mitochondrial fatty acid β-oxidation (FAO) is essential for energy production and cellular homeostasis, yet its specific role in sperm function has remained unclear. Through whole-exome sequencing of 673800 patients with asthenozoospermia, we identified biallelic TEX44 variants in six individuals...

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...

MetabolomicsChronic exposure to tire rubber-derived contaminant 6PPD-quinone impairs sperm quality and induces the damage of reproductive capacity in male mice

The study investigates the effects of 6PPDQ on male fertility in adult mice. The findings of this study are essential as the effects of low-dose environmental factors of 6PPDQ on adult male infertility are unclear, with the increasing in male infertility. The results suggest that 6PPDQ adversely ...

TranscriptomicsBiogenesis and function of tRNA fragments during sperm maturation and fertilization in mammals (single embryo)
Parental dietary conditions can influence the metabolic traits of offspring. In mice, paternal consumption of low protein diet alters cholesterol and lipid metabolism of progeny. Here, we examine RNA species expressed in male reproductive tissues of mice. Protein restriction leads to altered levels ...

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...

GenomicsHigh-resolution mapping of chromatin packaging in mouse embryonic stem cells and sperm
Mammalian embryonic stem (ES) cells and sperm exhibit unusual chromatin packaging that plays important roles in cellular function. Here, we extend a recently developed technique, based on deep paired-end sequencing of lightly digested chromatin, to assess footprints of nucleosomes and other DNA-bind...

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...

TranscriptomicsSpermatozoal mRNA is reproducibly detected in purified D. melanogaster sperm.
It is now well established that mature mammalian spermatozoa carry a population of mRNA molecules, at least some of which are transferred to the oocyte at fertilisation. However, the function of the sperm transcriptome remains largely unclear. To shed light on the evolutionary conservation of this...
