Taurine bulls are highly susceptible to heat stress, leading to increased oxidative stress (OS) and impaired sperm viability. Polyunsaturated fatty acids (PUFAs) supplementation can be an alternative to improve semen quality, which also results in more sperm susceptibility to lipid peroxidation. Moreover, this deleterious effect can be exacerbated in animals affected by heat stress. Vitamin E is a key antioxidant that counteracts lipid peroxidation of sperm membrane caused by OS. Thus, combining PUFAs with vitamin E may improve sperm quality...

Lactoferrin (LF), an ~80 kDa iron-binding glycoprotein, modulates many biological effects, including antimicrobial and immunomodulatory activities. Recently, it was shown that LF also regulates bone cell activity, suggesting its therapeutic effect on postmenopausal bone loss. However, a minimal amount is known regarding the effects of recombinant human LF (rhLF) supplementation on bone status in young healthy infants. We found osteoblast cell differentiation was significantly promoted in vitro. Furthermore, treatment of human osteoblast cells with rhLF rapidly induced phosphorylation of p44/p42 mitogen-activated protein kinase (p44/p42 MAPK, ERK1/2)...

The allelic variants of immunity genes in historical breeds likely reflect local infection pressure and therefore represent a reservoir for breeding. Screening to determine the diversity of the Toll-like receptor gene TLR4 was conducted in two conserved cattle breeds: Czech Red and Czech Red Pied. High-throughput sequencing of pooled PCR amplicons using the PacBio platform revealed polymorphisms, which were subsequently confirmed via genotyping techniques. Eight SNPs found in coding and adjacent regions were grouped into 18 haplotypes, representing a significant portion of the known diversity in the global breed panel and presumably exceeding diversity in production populations...

Peroxisome-proliferator-activated receptor gamma (PPARγ) is a key transcription factor that controls adipocyte differentiation and energy in mammals. Therefore, PPARγ is a potential factor influencing animal growth traits. This study primarily evaluates PPARγ as candidate gene for growth traits of cattle and identifies potential molecular marker for cattle breeding. Per previous studies, PPARγ mRNA was mainly expressed at extremely high levels in adipose tissues as shown by quantitative real-time polymerase chain reaction analysis...

Viral infections can play direct or indirect roles in the etiology of the bovine mastitis. Mx dynamin-like GTPase 2 (MX2) gene is a main effector of the antiviral innate immune defense mediated by type I interferon (IFN I), which was demonstrated to confer positive antiviral responses to many viruses. Given the importance of the MX2 in modulating the host immune response, MX2 gene may be a suitable candidate gene for studying disease resistance in dairy cattle. Here, we scanned the sequence variation of the MX2 gene in Chinese indigenous cattle breeds...

Myostatin (MSTN) is a well-known negative regulator of skeletal muscle development. Reduced expression due to natural mutations in the coding region and knockout as well as knockdown of MSTN results in an increase in the muscle mass. In the present study, we demonstrated as high as 60 and 52% downregulation (p < 0.01) of MSTN mRNA and protein in the primary fetal myoblast cells of goats using synthetic shRNAs (n = 3), without any interferon response. We, for the first time, evaluated the effect of MSTN knockdown on the expression of MRFs (namely, MyoD, Myf5), follistatin (FST), and IGFs (IGF-1 & IGF-2) in goat myoblast cells...

Myostatin (MSTN), also named growth differentiation factor 8 (GDF8), is a transforming growth factor-β (TGF-β) family member with a key role in the negative regulation of skeletal muscle growth. However, its role in ovarian folliculogenesis remains unclear. To provide us with a basis for understanding this role, we cloned MSTN and examined its expression patterns in water buffalo (Bubalus bubalis). The complete ORF of the water buffalo MSTN gene is 1,128 nucleotides, which encode a 375 amino acid protein and sharing 99% identity at the deducted amino acid level with that of Bos taurus...

Bone is a plastic tissue with a large healing capability. However, extensive bone loss due to disease or trauma requires extreme therapy such as bone grafting or tissue-engineering applications. Presently, bone grafting is the gold standard for bone repair, but presents serious limitations including donor site morbidity, rejection, and limited tissue regeneration. The use of stem cells appears to be a means to overcome such limitations. Bone marrow mesenchymal stem cells (BMSC) have been the choice thus far for stem cell therapy for bone regeneration...

Numerous studies have demonstrated that FTO plays an important role in adipogenesis. Herein, we designed a small interfering RNA targeting FTO to knock down its endogenous expression and investigated its effects on the proliferation and differentiation of porcine intramuscular preadipocytes. Its possible mechanism was also investigated. We showed that FTO silencing significantly decreased the level of phospho-Histone H3 protein and inhibited the proliferation of porcine intramuscular preadipocytes. In addition, the expressions of peroxisome proliferators-activated receptor γ (PPARγ) and CAAT/enhancer binding protein (C/EBPα) were down-regulated, but the expression of β-catenin was up-regulated, by FTO silencing...
