Project description:Despite buffaloes being primary farm animals, their reproductive performance remains poor mainly due to inaccurate estrus detection methods that ultimately has an economic impact on dairy industry as well as farmers. Recently, numerous studies showed potential of miRNAs as estrus biomarker. However, a miRNA profile of buffalo cell free saliva, a non-invasive fluid, at estrus and diestrus stages is missing. Hence, the present study was planned to identify differential levels of salivary cell free miRNAs in estrus as compared to the diestrus phase of buffalo oestrous cycle (n=3) in order to discover a possible estrus specific miRNAs as biomarkers. miRNA-Seq data analysis showed that in total 10 miRNAs i.e bta-miR-375, bta-miR-200c, bta-miR-30d, bta-let-7f, bta-miR-200a, bta-miR-12034, bta-let-7b, bta-miR-142-5p, bta-miR-2467-3p, bta-miR-30a-5p are significantly altered (log2foldchange >3 and p<0.05) during estrus in comparison to the diestrus phase in buffaloes, suggesting their estrus biomarker potential. Overall, 8 miRNAs i.e bta-miR-375 (6.87 Fold; p-value 0.003), bta-miR-200c (5.98 Fold; p-value 0.003), bta-miR-30d (4.17 Fold; p-value 0.015), bta-let-7f (3.34 Fold; p-value 0.022), bta-miR-200a (4.92 Fold; p-value 0.024), bta-miR-12034 (3.58 Fold; p-value 0.0025), bta-let-7b (3.06 Fold; p-value 0.031), bta-miR-30a-5p (4.7 Fold; p-value 0.036) were upregulated, whereas bta-miR-142-5p (-3.4 Fold; p-value 0.032) and bta-miR-2467-3p (-5.24 Fold; p-value 0.035) were downregulated during estrus. However, further validation study using qPCR is required in a large sample size in order to determine their estrus biomarker potential. In summary, our results revealed differential salivary cell free miRNAs profile during the oestrous cycle that may lead to the development of estrus specific miRNAs based point-of-care test applicable for the reproductive management of buffaloes in the field condition in the near future.

Project description:Background:The morphology of vaginal secretions during estrus and diestrus is characteristic and easy to distinguish. There are also significant differences in hormone levels between the two periods in physiological condition. However, the gene changes during estrus cycle especially the two periods are still unclear. Therefore, this study plans to find out the pathway changes related to the estrus cycle of female mice, the expression of various proteins, predict the genes sensitive to hormone changes in vivo through gene analysis of 15 tissues in the two periods and construct of differential gene expression library. Methods:The wildtype healthy female mice in estrus were compared with those in diestrus. The transcriptome changes between the two periods were probed by using high-throughput RNA-seq techniques. Results:A comprehensive mouse transcriptome map in estrus or diestrus across fifteen tissues including aorta, vein, brown adipose tissue, white adipose tissue, heart, kidney, liver, skeletal muscle, stomach, duodenum, cerebrum, hypothalamus, ovary, womb and spleen were provided. Conclusions:This dataset could serve as a baseline resource for investigating the potential gene changes sensitive to the estrus cycle across different tissues and provide the information for screening the key functional genes or molecular markers of estrus cycle.

Project description:BACKGROUND: Microsatellite markers are highly polymorphic and widely used in genome mapping and population genetic studies in livestock species. River buffalo, Bubalus bubalis is an economically important livestock species, though only a limited number of microsatellite markers have been reported thus far in this species. RESULTS: In the present study, using two different approaches 571 microsatellite markers have been characterized for water buffalo. Of the 571 microsatellite markers, 498 were polymorphic with average heterozygosity of 0.51 on a panel of 24 unrelated buffalo. Fisher exact test was used to detect LD between the marker pairs. Among the 137550 pairs of marker combination, 14.58% pairs showed significant LD (P < 0.05). Further to check the suitability of these microsatellite markers to map these on a radiation hybrid map of buffalo genome, the markers were tested on Chinese hamster genomic DNA for amplification. Only seven of these markers showed amplification in Chinese hamster, and thus 564, of these can be added to the radiation hybrid map of this species. CONCLUSION: The high conservation of cattle microsatellite loci in water buffalo promises the usefulness of the cattle microsatellites markers on buffalo. The polymorphic markers characterised in this study will contribute to genetic linkage and radiation hybrid mapping of water buffalo and population genetic studies.

Project description:More than 40 million households in India depend at least partially on livestock production. Buffaloes are one of the major milk producers in India. The prolactin receptor (PRLR) gene and peroxisome proliferators activated receptor-? coactivator 1-alpha (PPARGC1A) gene are reportedly associated with milk protein and milk fat yields in Bos taurus. In this study, we sequenced the PRLR and PPARGC1A genes in the water buffalo Bubalus bubalis. The PRLR and PPARGC1A genes coded for 581 and 819 amino acids, respectively. The B. bubalis PRLR gene differed from the corresponding Bos taurus at 21 positions and four differences with an additional arginine at position 620 in the PPARGC1A gene were found in the amino acid sequence. All of the changes were confirmed by cDNA sequencing. Twelve buffalo-specific single nucleotide polymorphisms (SNPs) were identified in both genes, with five of them being non-synonymous.

Project description:Toxoplasmosis and neosporosis are diseases with worldwide distribution that are associated with reproductive problems in livestock and responsible for economic losses. This review presents an overview of the current knowledge relative to these diseases in water buffalo (Bubalus bubalis). In general, buffalo are considered resistant to clinical toxoplasmosis because there are studies only reporting serological evidence of natural infection in these animals. Studies have described age, poor hygienic status of the farm, and presence of cats as risk factors for the development of Toxoplasma gondii infection in buffalo. It must be highlighted that buffalo meat, which does not receive adequate freezing treatment, could be a potential source for toxoplasmic human infection as well as the importance of raw buffalo milk in the transmission of toxoplasmosis to human beings. Neospora caninum is considered one of the major causes of abortion and responsible for huge economic losses in cattle. Vertical transmission is the main route to infect calves, and is responsible for maintaining the parasite within a herd. In buffalo, vertical transmission is also described; moreover, although there are indications that N. caninum may be associated with abortion in dairy buffalo, the reproductive importance of neosporosis is apparently lower in buffalo relative to cattle. Most studies have identified a higher time of exposition to N. caninum oocysts relative to age. The household system was also described as a risk factor for infection, possibly due to persistent contact between the home-raised buffalo and canids. The fetal immune competence of buffalo is similar to bovine, and buffalo fetus are highly susceptible to infection during the first trimester of pregnancy, indicating that N. caninum may be an abortigenic agent in buffaloes. Alternatively, it is interesting to note there is evidence that the inflammatory response in pregnant buffalo infected with N. caninum is mild enough to avoid abortion in most cases. It is proposed that the possible transmission of toxoplasmosis through unprocessed milk and buffalo meat may occur, which is important in terms of public health. Additionally, there is strong evidence to suggest that N. caninum may be associated with abortion in buffalo.

Project description:Brucellosis is a costly disease of water buffaloes (Bubalus bubalis). Latent infections and prolonged incubation of the pathogen limit the efficacy of programs based on the eradication of infected animals. We exploited genetic selection for disease resistance as an approach to the control of water buffalo brucellosis. We tested 231 water buffalo cows for the presence of anti-Brucella abortus antibodies (by the agglutination and complement fixation tests) and the Nramp1 genotype (by PCR-denaturing gradient gel electrophoresis). When the 231 animals (58 cases and 173 controls) were divided into infected (seropositive) and noninfected (seronegative) groups and the Nramp1 genotypes were compared, the seropositive subjects were 52 out of 167 (31%) in the Nramp1A+ (Nramp1AA or Nramp1AB) group and 6 out of 64 (9.4%) in the Nramp1A- (Nramp1BB) group (odds ratio, 4.37; 95% confidence limits, 1.87 to 10.19; chi2, 11.65 for 1 degree of freedom). Monocytes from Nramp1BB subjects displayed significantly (P < 0.01) higher levels of Nramp1 mRNA than Nramp1AA subjects and also a significantly (P < 0.01) higher ability in controlling the intracellular replication of several Brucella species in vitro. Thus, selection for the Nramp1BB genotype can become a valuable tool for the control of water buffalo brucellosis in the areas where the disease is endemic.

Project description:The Hox complex contains 39 genes clustered into four groups involved in cell differentiation and development. We cloned full-length sequence of Hoxc11 gene from water buffalo Bubalus bubalis, assessed its copy number, localized the same onto the chromosome 5, and studied its evolutionary conservation across the species. Northern hybridization of Hoxc11 showed a 2.2 kb band in the tissues analyzed. Real-Time PCR showed highest expression of Hoxc11 gene in lung followed by spleen, spermatozoa, and testis. Six interacting partners of this gene showed higher expression in spleen, lung, testis, and spermatozoa. During the early stages of development, Hoxc11 and its interacting partners both showed lower expression, which then became prominent during the age of 1-3 years, regressed drastically thereafter, and remained so until the animal's life time (? 20 years). The high expression of Hoxc11 and its interacting partners in spermatozoa and testis during the onset of puberty suggests its likely role in the differentiation of gonads and subsequent reproductive activities. Additional work on Hoxc11 especially, in the context of respiratory, immunological, and in/fertility in other species, including humans would be useful for establishing its broader biological significance towards the enrichment of functional and comparative genomics.

Project description:Stem cells present an important tool in livestock assisted reproduction and veterinary therapeutic field such as tissue engineering. We report for the first time isolation of pluripotent stem cell-like cells expressing pluripotency markers (alkaline phospahatase, OCT-4, NANOG and SOX-2) from the amnion of water buffalo (Bubalus bubalis). The cells showed no apparent abnormalities in their chromosomal profiles before and after cryopreservation. The cytochemical staining revealed that pluripotent cells were capable of undergoing directed differentiation in vitro into osteocytes. It could be inferred that amnion-derived pluripotent stem cell-like cells can be isolated, cultured for many passages and differentiated into mesoderm lineage, and may be an alternative source to mesenchymal stem cells. These cells can have applications in assisted reproduction, developmental biological and regenerative medicine.

Project description:In the present study, water buffalo MHC (Bubu)-DRB cDNA was cloned and characterized. The 1022 base long-amplified cDNA product encompassed a single open reading frame of 801 bases that coded for 266 amino acids. The Bubu-DRB sequence showed maximum homology with the BoLA-DRB3*0101 allele of cattle. A total of seven amino acid residues were found to be unique for the Bubu-DRB sequence. The majority of amino acid substitutions was observed in the β(1) domain. Residues associated with important functions were mostly conserved. Water buffalo DRB was phylogenetically closer to goat DRB*A.
