Project description:Mammary epithelial cells (MECs) have strong secretory function, which is an important target cell for studying mammary gland bioreactor. It is also a unique cell with lactation function in mammary gland. It can be used to study cell biological characteristics and molecular biological mechanism in the process of mammary gland growth, development and lactation. At present, mammary epithelial cells are obtained from mammary tissue, and the extraction of tissue block involves surgical anesthesia, which may lead to breast tissue injury and infection. This study aimed to describe the process of isolating and culturing goat mammary epithelial cells (GMECs) from goat milk, and to identify the biological characteristics of GMECs. Our study laid a foundation for the study of the regulation mechanism of mammary gland development and lactation, the improvement of milk quality, the increase of milk production and the establishment of mammary gland bioreactor.

Project description:Dietary supplementation with fish-oil modulates ruminant milk composition towards a healthier fatty acid profile for consumers, but it also causes milk fat depression (MFD). Because the dairy goat industry is mainly oriented towards cheese manufacturing, MFD can elicit economic losses. There is large individual variation in animal susceptibility with goats more (RESPO+) or less (RESPO−) responsive to diet-induced MFD. Thus, we used RNA-Seq to examine gene expression profiles in mammary cells to elucidate mechanisms underlying MFD in goats and individual variation in the extent of diet-induced MFD.

Project description:Fat metabolism is a complicated process regulated by a series of factors. microRNAs (miRNAs) are a class of negative regulator of proteins and play crucial roles in many biological processes, including fat metabolism. Although there have been some researches indicating that miRNAs could influence the milk fat metabolism through targeting some factors, little is known about the effect of miRNAs on goat milk fat metabolism. Here we utilized an improved miRNA detection assay, S-Poly(T), to profile the expression of miRNAs in the goat mammary gland in early-lactation and dry-lactation. Overall, we found 146 miRNAs expression changed between early-lactation and dry-lactation, with 81 up-regulation and 65 down-regulation, among which the miR-27a, miR-200a and miR-200c have been reported to be involved in the milk fat metabolism process.

Project description:The nutritional value of goat milk varies depending on the lactation time(Y. Zhang, Zheng, Liu, & Liu, 2020). Tandem mass tagging (TMT) was employed in this study to explore the differential proteome of mature milk and terminal milk from Guanzhong dairy goats. Goat mature milk was beneficial in the treatment and improvement of malaria patients, as well as in the treatment of pancreatic cancer patients. Terminal milk has been proven to promote angiogenesis, boost antibacterial and anti-inflammatory factor activity, and inhibit tumor formation. These bioinformatics investigations will provide new insights into the physiological activities of proteins in goat milk from Guanzhong dairy goats, as well as a scientific foundation for future study into the creation of specialized functionalised dairy products, such as cancer prevention.

Project description:This investigation reports a differential proteomic analysis of the goat milk to evaluate and understand the protein changes induced by Staphylococcus spp. during a subclinical intramammary infection (IMI). A number of 9 milk samples from multiparous goats were selected for the study, 3 of which in mid-lactation (30-60 Days in milk - DIM) with very low somatic cell count (SCC) from half-udders producing a sterile milk bacterial culture (MLU), 3 of which in late lactation samples (> 250 DIM) with SCC > 2,000,000 cells/mL from half-udders producing a sterile milk bacterial culture for the whole lactation (LHU) and in conclusion 3 in late lactation (> 250 DIM) with SCC > 2,000,000 cells/mL from goat half-udders with a milk bacterial culture repeatedly positive for Staphylococcus aureus (LHS). Samples were analyzed using a shotgun proteomics approach, based on filter-aided sample preparation (FASP) followed by LC-MS/MS and on differential analysis conducted by spectral count approach (1).

Proteomic changes in the milk of water buffaloes (Bubalus bubalis) with subclinical mastitis due to intramammary infection by Staphylococcus aureus and by non-aureus staphylococci. Sci Rep, 2019, 9 (1), 15850. Here, we reported both a characterization of goat milk proteins and a panel of differential proteins specific of S. Aureus-infected milk that mostly affected proteins involved in defense response processes and cytoskeleton organization. In conclusion, our results provide a depth characterization of milk proteins in goat samples uninfected and infected with S. Aureus, describe the changes induced by LHU and LHS subclinical intramammary infection and suggest indications to reveal subclinical staphylococcal mastitis in goat by a proteomic investigation of milk.
