A hypothesis that many potential Translational Control Elements (TCEs) may have stable secondary structures which are conserved across closely related genomes has been investigated. The 3’-UTR sequences and PAC (Poly-Adenylation Cleavage) sites information of Human and Mouse orthologous genes have been analyzed. It has been found that orthologous genes usually have very similar 3’-UTR sequences...

Spermatogenesis is a dynamic developmental process requiring precisely timed transitions between discrete stages. Specifically, the germline undergoes three transitions: from mitotic spermatogonia to spermatocytes, from meiotic spermatocytes to spermatids, and from morphogenetic spermatids to spermatozoa. The somatic cells of the testis provide essential support to the germline throughout sperm...

One striking pattern in molecular evolution is that genes encoding proteins involved in reproduction tend to evolve rapidly. Seminal fluid proteins frequently exhibit this pattern and directly affect multiple reproductive processes including enhancing sperm performance and mediating postmating sexual selection. Here, we investigate molecular evolutionary patterns of genes expressed in the foam ...

Mammalian testis development and spermatogenesis play critical roles in male fertility and continuation of a species. Previous research into the molecular mechanisms of testis development and spermatogenesis has largely focused on the role of protein-coding genes and small non-coding RNAs, such as microRNAs and piRNAs. Recently, it has become apparent that large numbers of long (>200 nt) non-co...

Activation of cancer promoting genes or silencing of tumour suppressors is often due to aberrant expression of transcription factors or transcriptional regulators; interestingly, the expression of many of these transcriptional regulators is usually restricted to male germ cells (Rousseaux et al, 2013; Simpson et al, 2005). The similarities between germ cell development and cancer have long been...

Objective(s): Here, we examined the function of our produced monoclonal antibody (mAb10C3) to recognize one of the most important members of the HEAT shock factor family, Hsf5, in embryonic development and in spermatogenic cells of adult mouse testis.Materials and Methods: The targeting effects of mAb10C3 were investigated by immunohisto...

Chinese mitten crab (Eriocheir sinensis) has the spermatozoa with typical aflagellate, decondensed chromatin, cup-shaped nuclei, and radial arms. However, the mechanism of spermatogenesis during which the specific spermatozoa are generated in this species is yet unclear. Here, the transcriptome of developing testis in E. sinensis was analyzed using the ways of RNA-seq and bioinformatics analysi...

Recent developments in high-throughput sequencing techniques have enabled large-scale analysis of genetic variations and gene expression in different tissues and species, but gene expression patterns and genetic variations in livestock are not well-characterized. In this study, we have used high-throughput transcriptomic sequencing of the Finnish Large White to identify gene expression patterns...

The accurate management of testicular germ cell tumors (TGCTs) depends on identifying the individual histological tumor components. Currently available data protein expression in TGCTs are limited. human atlas (HPA) is a comprehensive resource presenting and localization proteins across tissue types diseases. In this study, we have compared from HPA with our in-house immunohistochemistry core T...

To identify genes that are differentially expressed in the developing testis we used representational difference analysis of complementary DNA from gonads of mouse embryos at 13.5 days postcoitum (dpc). Three genes were identified. One of them was a novel gene termed tescalcin that encoded a putative EF-hand Ca(2+)-binding protein. The open reading frame consisted of 642 nucleotides encoding a ...
