Bromodomain and extraterminal domain (BET) promote autophagy in buffalo sertoli cells.

Sertoli cells (SCs) play a pivotal role in spermatogenesis, with autophagy modulation being an evolutionarily conserved mechanism for maintaining cellular homeostasis and protecting spermatogenic cells against apoptosis. The bromodomain and extraterminal domain (BET) family are transcriptional regulators of autophagy. This study investigated the relationship between BET inhibition and autophagy in buffalo SCs.

Padi6 expression patterns in buffalo oocytes and preimplantation embryos.

The subcortical maternal complex, which consists of maternal-effect genes, plays a crucial role in the development of oocytes and preimplantation embryo until the activation of the zygote genome. One such gene, known as peptidyl-arginine deiminase VI (), is involved in the oocyte maturation, fertilization and embryonic development. However, the precise function of gene in buffalo is still unclear and requires further investigation.

Proteomic and antimicrobial peptide analyses of Buffalo colostrum and mature Milk whey: A comparative study.

Buffalo colostrum is the initial mammary secretion after parturition, consisting of nutritional and bioactive components. In this study, we conducted a proteomic analysis of buffalo colostrum whey to identify bioactive proteins and peptides. A total of 107 differentially expressed proteins (DEPs) were identified in buffalo colostrum whey compared to those in mature milk.

Comparative proteomic analysis of seminal plasma exosomes in buffalo with high and low sperm motility.

Background: Exosomes are nanosized membranous vesicles secreted by various types of cells, which facilitate intercellular communication by transporting bioactive compounds. Exosomes are abundant in biological fluids including semen, and their protein composition and the potential of seminal plasma exosomes (SPEs) as fertility biomarkers were elucidated in humans, however, little information is available regarding buffalo (Bubalus bubalis). Here, we examined protein correlation between spermatozoa, seminal plasma (SP), and SPEs, and we compared and analyzed protein differences between high-motility (H-motility) and low-motility (L-motility) SPEs in buffalo.

Single-cell RNA sequencing uncovers dynamic roadmap and cell-cell communication during buffalo spermatogenesis.

Spermatogenesis carries the task of precise intergenerational transmission of genetic information from the paternal genome and involves complex developmental processes regulated by the testicular microenvironment. Studies performed mainly in mouse models have established the theoretical basis for spermatogenesis, yet the wide interspecies differences preclude direct translation of the findings, and farm animal studies are progressing slowly. More than 32,000 cells from prepubertal (3-month-old) and pubertal (24-month-old) buffalo testes were analyzed by using single-cell RNA sequencing (scRNA-seq), and dynamic gene expression roadmaps of germ and somatic cell development were generated.

Comparative Proteomic Analyses of Poorly Motile Swamp Buffalo Spermatozoa Reveal Low Energy Metabolism and Deficiencies in Motility-Related Proteins.

The acquisition of mammalian sperm motility is a main indicator of epididymal sperm maturation and helps ensure fertilization. Poor sperm motility will prevent sperm cells from reaching the fertilization site, resulting in fertilization failure. To investigate the proteomic profiling of normal and poorly motile buffalo spermatozoa, a strategy applying liquid chromatography tandem mass spectrometry combined with tandem mass targeting was used.

Quercetin Alleviates Endoplasmic Reticulum Stress-Induced Apoptosis in Buffalo Ovarian Granulosa Cells.

Endoplasmic reticulum (ER) stress plays a crucial role in granulosa cell (GCs) apoptosis, which is the main cause of follicular atresia. Quercetin (QC), a plant-derived flavonoid, has antioxidant, anti-inflammatory, and other biological properties. However, whether QC can alleviate the effects of ER stress on buffalo GCs remains unknown.

Genomic Identification, Evolution, and Expression Analysis of Bromodomain Genes Family in Buffalo.

Bromodomain (BRD) is an evolutionarily conserved protein-protein interaction module that is critical in gene regulation, cellular homeostasis, and epigenetics. This study aimed to conduct an identification, evolution, and expression analysis of the BRD gene family in the swamp buffalo (). A total of 101 BRD protein sequences deduced from 22 BRD genes were found in the buffalo genome.

Nlrp5 and Tle6 expression patterns in buffalo oocytes and pre-implantation embryos.

Maternal-effect genes (MEGs) accumulate in oocytes during oogenesis and mediate the pre-implantation embryo developmental programme until activation of the zygote genome. Nlrp5 and Tle6 are required for normal pre-implantation and embryonic development. However, the precise function of these MEGs in buffalo (Bubalus bubalis) remains to be elucidated.
