Glutathione-S-transferases mu 2 (GSTM2), a kind of important Phase II antioxidant enzyme of eukaryotes, is degraded by nonsense mediated mRNA decay due to a C27T substitution in the fifth exon of pigs. As a reproductive performance-related gene, GSTM2 is involved in embryo implantation, whereas, functional deficiency of GSTM2 induces pre- or post-natal death in piglets potentially. To have some insight into the role of GSTM2 in embryo development, high throughput RNA sequencing is performed using the swine testis cells (ST) with the deletion of GSTM2...

CD147 null mutant male mice are infertile with arrested spermatogenesis and increased apoptotic germ cells. Our previous studies have shown that CD147 prevents apoptosis in mouse spermatocytes but not spermatogonia. However, the underlying mechanism remains elusive. In the present study, we aim to determine the CD147-regulated apoptotic pathway in mouse spermatocytes. Our results showed that immunodepletion of CD147 triggered apoptosis through extrinsic apoptotic pathway in mouse testis and spermatocyte cell line (GC-2 cells), accompanied by activation of non-canonical NFκB signaling and suppression of canonical NFκB signaling...

BACKGROUND: Cryptozoospermia (CO) is a situation in which spermatozoa cannot be observed in a fresh semen sample unless an extended centrifugation and microscopic search are performed. CO patients are suggested to use only intracytoplasmic sperm injection (ICSI) as infertility treatment. But still there is debate about the choice of sperm source in cryptozoospermic men candidate for ICSI. OBJECTIVES: This study was conducted to evaluate fertility outcomes in men with idiopathic cryptozoospermia who were treated using ICSI with freshly ejaculated sperm and testis sperm extraction (TESE) or percutaneous epididymal sperm aspiration (PESA)...

BACKGROUND: The expression of sexually selected traits often varies with populations' breeding cycles in many animals. The elucidation of mechanisms underlying the expression of such traits is a research topic in evolutionary biology; however, the genetic basis of the seasonal development of their expression remains unknown. Male Leptobrachium boringii develop keratinized nuptial spines on their upper jaw during the breeding season that fall off when the breeding season ends. To illuminate the genetic basis for the expression of this trait and its seasonal development, we assessed the de novo transcriptome for L...

Atlantic salmon is a valuable commercial aquaculture species that would benefit economically and environmentally by controlling precocious puberty and preventing escapees from reproducing with wild populations. One solution to both these challenges is the production of sterile individuals by inhibiting the formation of germ cells, but achieving this requires more information on the specific factors that control germ cell formation. Here, we identified and characterized novel factors that are preferentially expressed in Atlantic salmon germ cells by screening for gonad-specific genes using available adult multi-tissue transcriptomes...

REVIEW
Anu Bashamboo, Caroline Eozenou, Sandra Rojo, Ken McElreavey
Human sex-determination (SD) involves complex mutually antagonistic genetic interactions of testis- and ovary-determining pathways. For many years both male and female sex-determination was considered to be regulated by a linear cascade of pro-male and pro-female genes respectively, however it has become clear that male and female development is achieved through the repression of the alternative state. A gene determining the formation of a testis may function by repressing the female state and vice-versa. Uniquely in development, SD is achieved by suppression of the alternate fate and maintained in adulthood by a mutually antagonistic double-repressive pathway...

Several species of cervids are currently classified as threatened or endangered due to a rapid decline in their populations. Sperm cryopreservation, in association with assisted reproductive technologies, can find application for the conservation of endangered cervids. In cases of unsuccessful sperm retrieval through other means prior to the death of the animal, adult testis is the only source of sperm. Recovery of viable sperm from adult testes depends on the effective preservation of testicular tissues through optimization of cryopreservation protocols...
