Abstract
Bovine mastitis, the inflammation of the mammary gland, is a contagious disease characterized by chemical and physical changes in milk and pathological changes in udder tissues. Depressed immunity and higher expression of inflammatory cytokines with an elevated milk somatic cell count can be observed during mastitis in dairy cattle. The use of somatic cell count (SCC) and somatic cell score (SCS) as correlated traits in the indirect selection of animals against mastitis resistance is in progress globally. Traditional breeding for mastitis resistance seems difficult because of the low heritability (0.10-0.16) of SCC/SCS and clinical mastitis. Thus, genetic-marker-selective breeding to improve host genetics has attracted considerable attention worldwide. Moreover, genomic selection has been found to be an effective and fast method of screening for dairy cattle that are genetically resistant and susceptible to mastitis at a very early age. The current review discusses and summarizes the candidate gene approach using polymorphisms in immune- and inflammation-linked genes (CD4, CD14, CD46, TRAPPC9, JAK2, Tf, Lf, TLRs, CXCL8, CXCR1, CXCR2, C4A, C5, MASP2, MBL1, MBL2, LBP, NCF1, NCF4, MASP2, A2M, and CLU, etc.) and their related signaling pathways (Staphylococcus aureus infection signaling, Toll-like receptor signaling, NF-kappa B signaling pathway, Cytokine-cytokine receptor, and Complement and coagulation cascades, etc.) associated with mastitis resistance and susceptibility phenotypic traits (IL-6, interferon-gamma (IFN-γ), IL17, IL8, SCS, and SCC) in dairy cattle.

Abstract
Recognition of deleterious non-synonymous single nucleotide polymorphism (SNPs) aids in the assessment of genetic basis of diseases and prediction of clinical phenotypes. In this study, data obtained from whole exome sequencing of Vechur cow using Illumina HiSeq 2500 platform is compared with that of crossbred cattle of Kerala. Sequence analysis of selected 18 mastitis resistant genes, evaluated the consequence of non-synonymous SNPs in these genes from both Vechur and crossbred cattle of Kerala, using sequence and structure-based computational tools such as SIFT, PROVEAN and I-MUTANT 2.0. Compared to Vechur cattle, incidence of missense deleterious mutation to effect protein functioning were relatively higher in crossbred cattle. These results on the type of genetic variants and its impact on normal functioning of a protein will assist to predict and enhance the disease resistance in cattle breeds.

Abstract
Gram‑negative (GN) bacterial infection is a main cause of bovine mastitis. The cluster of differentiation (CD) 14 gene serves an essential role in GN bacterium‑induced innate immune response. CD14 works as a bacterial lipopolysaccharide (LPS) receptor, combines with LPS‑liposaccharide binding protein complex, and causes cellular activation. However, the effects of CD14 single nucleotide polymorphisms (SNPs) on morbidity of clinical mastitis remain unclear. In the present study, To investigate the polymorphisms of CD14 gene and its effects on cows' susceptibility to mastitis, polymerase chain reaction‑single‑strand conformation polymorphism (PCR‑SSCP) assay was used to detect SNPs of CD14 gene in 134 Chinese Holsteins. SNPs were identified in PCR products amplified with 3 sets of primers in CD14 exon 2. A total of three SNPs were located in that exon: g.528 A→C (147Ser→Arg) in allele B; g.612 A→G (175Asn→Asp) in allele D; and g.1022 A→G in allele F (synonymous mutation). The SNPs in alleles B and D affected the secondary structure of CD14. A 3‑dimensional (3D) structural analysis predicted three potential protein forms with a similar structure and indicated that the changes of the above‑mentioned alleles were on the concave surface of the protein. In more detail, 147 Ser→Arg induced a protein kinase C phosphorylation site to move forward, as assessed by the motif analysis. The morbidity rate of AB (mixed type g.528 A/C) and CD (mixed type g.612 A/G) was the highest among all genotypes presented in the current study, and via of tumor necrosis factor‑α and interleukin‑6 mRNA levels were upregulated in animals of this genotype compared with others. Taken together, the CD14 SNPs identified in the present study, may be closely associated with the morbidity of mastitis.

Cell Stress Chaperones 2016; 21:439-52. [PMID: 26813383 PMCID: PMC4837180 DOI: 10.1007/s12192-016-0671-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2015] [Revised: 01/11/2016] [Accepted: 01/12/2016] [Indexed: 12/26/2022] Open
Abstract
Lipopolysaccharide (LPS)-binding protein (LBP) plays a crucial role in the recognition of bacterial components, such as LPS that causes an immune response. The aim of this study was to compare the different effects of recombinant bovine wild LBP and mutant LBP (67 Ala → Thr) on the LPS-induced inflammatory response of bovine mammary epithelial cells (BMECs). When BMECs were treated with various concentrations of recombinant bovine lipopolysaccharide-binding protein (RBLBP) (1, 5, 10, and 15 μg/mL) for 12 h, RBLBP of 5 μg/mL increased the apoptosis of BMECs induced by LPS without cytotoxicity, and mutant LBP resulted in a higher cell apoptosis than wild LBP did. By gene-chip microarray and bioinformatics, the data identified 2306 differentially expressed genes that were changed significantly between the LPS-induced inflamed BMECs treated with 5 μg/mL of mutant LBP and the BMECs only treated with 10 μg/mL of LPS (fold change ≥2). Meanwhile, 1585 genes were differently expressed between the inflamed BMECs treated with 5 μg/mL of wild LBP and 10 μg/mL of LPS-treated BMECs. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses showed that these differentially expressed genes were involved in different pathways that regulate the inflammation response. It predicted that carriers of this mutation increase the risk for a more severe inflammatory response. Our study provides an overview of the gene expression profile between wild LBP and mutant LBP on the LPS-induced inflammatory response of BMECs, which will lead to further understanding of the potential effects of LBP mutations on bovine mammary glands.

Whole-genome sequencing of the endangered bovine species Gayal (Bos frontalis) provides new insights into its genetic features. Sci Rep 2016; 6:19787. [PMID: 26806430 PMCID: PMC4726396 DOI: 10.1038/srep19787] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2015] [Accepted: 12/18/2015] [Indexed: 12/21/2022] Open
Abstract
Gayal (Bos frontalis) is a semi-wild and endangered bovine species that differs from domestic cattle (Bos taurus and Bos indicus), and its genetic background remains unclear. Here, we performed whole-genome sequencing of one Gayal for the first time, with one Red Angus cattle and one Japanese Black cattle as controls. In total, 97.8 Gb of sequencing reads were generated with an average 11.78-fold depth and >98.44% coverage of the reference sequence (UMD3.1). Numerous different variations were identified, 62.24% of the total single nucleotide polymorphisms (SNPs) detected in Gayal were novel, and 16,901 breed-specific nonsynonymous SNPs (BS-nsSNPs) that might be associated with traits of interest in Gayal were further investigated. Moreover, the demographic history of bovine species was first analyzed, and two population expansions and two population bottlenecks were identified. The obvious differences among their population sizes supported that Gayal was not B. taurus. The phylogenic analysis suggested that Gayal was a hybrid descendant from crossing of male wild gaur and female domestic cattle. These discoveries will provide valuable genomic information regarding potential genomic markers that could predict traits of interest for breeding programs of these cattle breeds and may assist relevant departments with future conservation and utilization of Gayal.

Abstract
Powdery mildew is a major disease of economic importance in cut and pot roses. As an alternative to conventional resistance breeding strategies utilizing single-dominant genes or QTLs, mildew resistance locus o (MLO)-based resistance might offer some advantages. In dicots such as Arabidopsis, pea, and tomato, loss-of-function mutations in MLO genes confer high levels of broad-spectrum resistance. Here, we report the isolation and characterization of four MLO homologs from a large rose EST collection isolated from leaves. These genes are phylogenetically closely related to other dicot MLO genes that are involved in plant powdery mildew interactions. Therefore, they are candidates for MLO genes involved in rose powdery mildew interactions. Two of the four isolated genes contain all of the sequence signatures considered to be diagnostic for MLO genes. We mapped all four genes to three linkage groups and conducted the first analysis of alternative alleles. This information is discussed in regards to a reverse genetics approach aimed at the selection of rose plants that are homozygous for loss-of-function in one or more MLO genes.
