Spermatozoal RNA Profiles (HumanRef-8 BeadChip)

(Submitter supplied) Normal human spermatogenesis concludes with the formation of large numbers of morphologically well developed spermatozoa. While transcriptionally quiescent these cells carry an RNA payload that reflects the final spermiogenic phase of transcription. We report here the spermatozoal transcript profiles characteristic of normally fertile individuals and infertile males suffering from a consistent and severe teratozoospermia in which under 4% of spermatozoa are morphologically normal. more...

rRNA cleavage ensures translational cessation in the mature sperm

(Submitter supplied) We report how unique RNA seq profiles of ribosomal RNA (18S, 28S) present in sperm indicate specific cleavage sites. Additionally, these sequencing results reveal how overall character of RNA (GC content) can significantly affect overall distribution of mapped reads.

Characterization of the small RNA population in Human spermatozoa

(Submitter supplied) Small noncoding RNAs (sncRNA) are becoming recognized for their participation in a diverse range of cellular functions. In this study, their global characterization in human spermatozoa from donors with proven fertility was undertaken. Reads were analyzed in two classes, those mapping to unique locations and those that could be aligned to up to 10 genomic locations. All libraries showed comparable distribution of reads between intergenic, intronic and exonic genomic regions. more...

Expression of Mouse and Human Sense-Antisense Transcript

(Submitter supplied) Increasing numbers of sense–antisense transcripts (SATs), which are transcribed from the same chromosomal location but in opposite directions, have been identified in various eukaryotic species, but the biological meanings of most SATs remain unclear. To improve understanding of natural sense–antisense transcription, we performed comparative expression profiling of SATs conserved among humans and mice. more...

Comparison of human epididymal gene expression in the caput epididymides of infertile and fertile patients

(Submitter supplied) Caput epididymides biopsies from 4 patients suffering from non-obstructive azoospermia and from 4 patients with active spermatogenesis were compared. 414 genes in the caput epididymides were differentially regulated in infertile men by at least a 2-fold change as compared to the fertile men.

Use of spermatozoal total RNA profiles to study gene-environment interactions in human germ cells

(Submitter supplied) Paternal exposure to genotoxic compounds is thought to contribute to diseases in their offspring. Therefore, mRNA profiles from sperm in ejaculates of cigarette smokers (N=4) were compared with non-smokers (N=4). Smoking behaviour was verified by assessing cotinine levels in seminal plasma. Gene-expression analysis was subsequently performed using microarray technology (Agilent human 4x44k) to investigate the use of gene-expression profiling as biomarker of gene-environment interactions in human testis

Expression data from brain tissue of Rattus norvegicus treated with D-Serine

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...

D-serine effect on the brain: dose response

Analysis of forebrains of animals treated with up to 500 mg/kg D-serine for 96 hours. D-serine is involved in many physiological processes through its interaction with the glycine binding site of the NMDA receptor. Results provide insight into the impact of D-serine exposure on neuronal functions.

Stallion sperm transcriptome as revealed by microarray analysis and RNA sequencing

(Submitter supplied) 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 directly aligned with the horse reference sequence EcuCab2 using ABI aligner software (NovoalignCS version 1.00.09, novocraft.com) which uses multiple indexes in the reference genome, identifies candidate alignment locations for each primary read, and allows completion of the alignment. more...

Region specific gene expression profiling along the human epididymis

The data generated in this study demonstrate a region specific gene expression pattern along the human epididymis that seems to coincide with the morphological distinctive features of the excurrent duct.

Spermatozoal mRNA is reproducibly detected in purified D. melanogaster sperm.

(Submitter supplied) 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 feature of sperm biology, we analysed highly purified populations of mature sperm from the fruitfly, Drosophila melanogaster. more...

The Transcript Integrity Index (TII) provides a standard measure of sperm RNA

(Submitter supplied) Human sperm RNA-seq was performed and sequences used for the generation of a RNA integrity index capable of assessing samples with high RNA fragmentation. A two-prong approach was used including both manual and computational analysis. This identified a series of sperm RNAs that are consistently intact, and acceptable for use in determining sample RNA quality. These RNAs function in roles related to spermatogenesis and/or fertilization.
