An endocannabinoid system comprising of Anandamide (AEA) and its receptor has been shown to play a role in sperm acquisition of fertilizing potential and sperm-oviduct interaction. In the present study, we assessed the effect of sperm pre-treatment with AEA or co-incubation of sperm-oviduct explants with AEA in the presence or absence of CB1 receptor antagonist (SR141716A) on sperm-oviduct binding in the water buffalo. Cryopreserved spermatozoa from 3 Murrah buffalo bulls (3 ejaculates from each bull) were utilized for the study...

Elevated intracellular calcium concentration and oxidative damage are two major factors contributing to the poor fertility of cryopreserved spermatozoa. Regucalcin (RGN), also known as Senescence marker protein-30 (SMP-30), is a calcium-binding protein with multiple roles that include calcium homeostasis, anti-oxidative, anti-apoptosis, and anti-proliferation. In Drosophila, regucalcin is reportedly a putative cold-tolerance gene, and a cryoprotective role for regucalcin against intracellular calcium elevation and oxidative stress was reported in P19 cell lines...

Buffalo DGAT1 (diacylglycerol O-acyltransferase 1) was mainly investigated for the characterization of the gene itself and for the identification of the K232A polymorphism, similar to what has been accomplished in cattle, although no information has been reported so far at the mRNA level. The importance of DGAT1 for lipid metabolism led us to investigate the transcript profiles of lactating buffaloes characterized as high (9.13 ± 0.23) and low (7.94 ± 0.29) for milk fat percentage, and to explore the genetic diversity at the RNA and DNA level...

Cryopreservation causes damage to spermatozoa, and methods minimizing this damage are therefore needed. Although much discussed, seminal plasma removal has become an alternative to improve sperm quality and viability after freezing and has been applied to different species in attempt to obtain good results. The objective of this study was to evaluate semen quality in buffaloes submitted to two methods for seminal plasma removal (filtration and centrifugation). Semen samples were collected from seven Murrah buffalo bulls (Bubalus bubalis) once a week for 8 weeks...

The use of frozen semen for artificial insemination is the main approach utilised for the genetic improvement of most domesticated species. The advantages include lower transportation costs, continuous availability of semen, fewer occurrences of sexually transmitted diseases and the incorporation of desirable genes in a relatively short amount of time. Nevertheless, the use of frozen semen in buffalo herds remains limited due to the loss of sperm quality when buffalo semen is frozen. So, the goal of this study was to evaluate the pre- and post-cryopreservation quality of buffalo semen diluted in three distinct freezing media: Tris-egg yolk, Botu-bov® (BB) and ACP-111®...

Although it is understood that spermatozoa are subjected to selection processes to form a functional sperm reservoir in the oviduct, the mechanism remains obscure. With the aim to understand the sperm selection process in the oviduct, in the present in vitro study, we analyzed mitochondrial membrane potential and tyrosine phosphorylation status in oviduct-explants bound and unbound spermatozoa. Frozen semen from Murrah buffalo bulls (n=10) used under progeny testing programme were utilized for the study. Oviduct explants were prepared by overnight culture of epithelial cells in TCM- 199 and washed spermatozoa were added to the oviduct explants and incubated for 4h...
