Abstract
Airway mucus constitutes a thin layer of airway surface liquid with component macromolecules that covers the luminal surface of the respiratory tract. The major function of mucus is to protect the lungs through mucociliary clearance of inhaled foreign particles and noxious chemicals. Mucus is comprised of water, ions, mucin glycoproteins, and a variety of other macromolecules, some of which possess anti-microbial, anti-protease, and anti-oxidant activities. Mucins comprise the major protein component of mucus and exist as secreted and cell-associated glycoproteins. Secreted, gel-forming mucins are mainly responsible for the viscoelastic property of mucus, which is crucial for effective mucociliary clearance. Cell-associated mucins shield the epithelial surface from pathogens through their extracellular domains and regulate intracellular signaling through their cytoplasmic regions. However, neither the exact structures of mucin glycoproteins, nor the manner through which their expression is regulated, are completely understood. This chapter reviews what is currently known about the cellular and molecular properties of airway mucins.

Abstract
An investigation was undertaken to study the association between the variable number of tandem repeats polymorphism of the Muc1 gene and the litter size in pigs. Four different alleles were found in three breeds. The sequence analysis shows that the repetitive region of pig Muc1 gene is an array of 108-bp repeats. A total of 2,430 litter records from 897 sows genotyped at Muc1 gene were used to analyze the total number born (TNB) and number born alive (NBA). The study of the effects on litter size suggests that TNB and NBA of genotype AA are the highest in Large White, and the TNB and NBA of the third to ninth parities are 1.61 and 2.29 piglets per litter higher (P < 0.05) than those of the genotype DD, respectively. In Landrace, TNB and NBA of the genotype AA are 1.68 (P < 0.01) and 1.58 (P < 0.05) piglets per litter higher than those of the BB genotype in the third to ninth parities, but for all parities the TNB of genotype AA were 0.76 piglets per litter (P < 0.05) higher than BB. In Duroc, the TNB and NBA of genotype AA are about 1.5 piglets per litter more than those of DD in the third to ninth parities, though not significantly. The research suggests that the smaller allele tends to have higher litter size. The results indicate that Muc1 gene is significantly associated with litter size in pigs.

Abstract
The objective of this study was to describe the VNTR polymorphism of the mucin 1 gene (MUC1) in three Nelore lines selected for yearling weight to determine whether allele and genotype frequencies of this polymorphism were affected by selection for growth. In addition, the effects of the polymorphism on growth and carcass traits were evaluated. Birth, weaning and yearling weights, rump height, Longissimus muscle area, backfat thickness, and rump fat thickness, were analyzed. A total of 295 Nelore heifers from the Beef Cattle Research Center, Instituto de Zootecnia de Sertãozinho, were used, including 41 of the control line, 102 of the selection line and 152 of the traditional. The selection and traditional lines comprise animals selected for higher yearling weight, whereas control line animals are selected for yearling weight close to the average. Five alleles were identified, with allele 1 being the most frequent in the three lines, especially in the lines selected for higher means for yearling weight. Heterozygosity was significantly higher in the control line. Association analyses showed significant effects of allele 1 on birth weight and weaning weight while the allele 3 exert significant effects on yearling weight and back fat thickness. Despite these findings, application of this marker to marker-assisted selection requires more consistent results based on the genotyping of a larger number of animals in order to increase the accuracy of the statistical analyses.

Abstract
The sheep has worldwide agricultural importance, yet the genetic control of the immune responses underlying susceptibility or resistance to ovine disease is little understood. Here, we identify six novel polymorphisms in the ovine immune response genes interferon-γ (IFNG), tumour necrosis factor-α (TNF), interleukin-1β (IL1B) and interleukin-4 (IL4) in pedigree Charollais flocks. We confirm the presence of previously reported polymorphisms in IFNG and IL1B in Charollais. Restriction fragment length polymorphism (RFLP) genotyping assays have been developed for four polymorphisms, IFNGg.168C>T, IFNGg.285A>G, IL1Bg.689C>T and TNFg.3UTRA>G, and a Taqman genotyping assay has been developed for IL4g.485C>T. The previously described IL2g.647C>T polymorphism is adapted for RFLP analysis. Allele frequencies are described in Charollais, Lleyn and Suffolk cross sheep. Polymorphisms are typed in both Charollais ewes and lambs and analysed against abortion phenotypes. A subset of animals have also been analysed for the presence of Toxoplasma gondii, an abortion-causing protozoan. The IFNGg.168T allele is shown to be associated with increased risk of a ewe having an abortion, while the IFNGg.285G allele is associated with increased risk of a lamb being aborted. These assays provide tools for the investigation of the genetic basis of other phenotypes in sheep, including infectious disease susceptibility.

Abstract
BACKGROUND Mucins are large glycoproteins implicated in protection of all mucosal surfaces. In humans and rodents, the mucin gene family has been well described and previous studies have investigated the distribution and function of mucins in the gastrointestinal (GI) tract. In contrast, little data is available on the mucin gene family in polygastric species, such as cattle. The aim of the current study was to identify all members of the bovine mucin family by genome mining and subsequently investigate the transcription pattern of these mucins in the GI tract. RESULTS Nine bovine membrane-associated mucins (MUC1, MUC3A, MUC4, MUC12, MUC13, MUC15, MUC16, MUC20 and MUC21) and six secreted mucins (MUC2, MUC5AC, MUC5B, MUC6, MUC7 and MUC19) were identified in the bovine genome. No homologues could be identified for MUC3B, MUC8 and MUC17. In general, domain architecture of the membrane-associated mucins was found to be similar between humans and cattle, while the protein architecture of the gel-forming mucins appeared to be less conserved. Further analysis of the genomic organization indicated that the previously reported bovine submaxillary mucin (BSM) may be part of a larger gene encoding for MUC19. Analysis of the transcription profile showed that the secreted mucins were transcribed from the abomasum onwards, whereas the membrane associated mucins MUC1 and MUC20 were transcribed throughout the whole GI tract. In contrast to humans, MUC5B transcript was found in both the small and large intestine, but was absent in oesophageal tissue. CONCLUSIONS This study provides the first characterization of the mucin gene family in cattle and their transcriptional regulation in the GI tract. The data presented in this paper will allow further studies of these proteins in the physiology of the GI tract in ruminants and their interactions with pathogens.

Abstract
The genotypes and protein polymorphisms of milk epithelial mucin (MUC1) were analyzed by touch-down PCR and SDS-PAGE respectively using blood samples and milk collected from 50 lactating yaks. A total of seven alleles were revealed, namely A, B, C, D, E, F, and G, and the corresponding number of repetitive units of variable number tandem repeat (VNTR) in MUC1 gene were 21, 20, 19, 18, 17, 16, and 15, respectively. Fifteen genotypes of MUC1 were observed in yaks. The genotypes of MUC1 gene matched completely to the phenotypes of milk MUC1 in each individual. This study demonstrated that the yak MUC1 exhibits abundant polymorphisms in both its gene and protein, and the polymorphisms are due to the expression of VNTR in MUC1 gene. The possible cluster of the VNTR was also discussed in different ruminants.

Abstract
MUC1 is a heavily glycosylated mammalian transmembrane protein expressed by mucosal secretory tissues for both protection against microbial infection and lubrication. An important characteristic of MUC1 is its variable number of tandem repeats (VNTR) containing several sites for O-glycosylation. VNTR length has been associated with many human diseases and with certain economically important traits in domestic ruminants. The aim of the present study was to correlate the length of MUC1 gene VNTR with expected progeny differences (EPDs) obtained for growth, fertility and carcass traits. Five alleles were identified, with alleles containing short VNTRs being more frequent than those with long, thereby demonstrating that Brazilian Nelore cattle are characterized by high frequencies in short MUC1 VNTRs. Statistical analyses revealed there to be no significant association between VNTR length and EPDs for weight at 120 days (W(120) ), scrotal circumference at 365 (SC (365) ) and 450 (SC (450) ) days, age at first calving (AFC), and rib eye area (REA).
