Abstract
Analyses of livestock genomes have been used to detect selection signatures, which are genomic regions associated with traits under selection leading to a change in allele frequency. The objective of the present study was to characterize selection signatures in Canchim composite beef cattle using cross-population analyses with the founder Nelore and Charolais breeds. High-density single nucleotide polymorphism genotypes were available on 395 Canchim representing the target population, along with genotypes from 809 Nelore and 897 Charolais animals representing the reference populations. Most of the selection signatures were co-located with genes whose functions agree with the expectations of the breeding programs; these genes have previously been reported to associate with meat quality, as well as reproductive traits. Identified genes were related to immunity, adaptation, morphology, as well as behavior, could give new perspectives for understanding the genetic architecture of Canchim. Some selection signatures identified genes that were recently introduced in Canchim, such as the loci related to the polled trait.

Abstract
Different allelic forms of bovine CD4 were previously described in cattle and were also observed in Canchim calves examined in the present experiment. However, the functional relevance of these different CD4 phenotypes has not yet been investigated. CD4 + T helper cells are known to play a central role in immune control against Babesia bovis infection. Thus, our study aimed to compare the profiles of immune cells, specific antibody titers and blood infection levels measured by qPCR (quantitative polymerase chain reaction) in calves naturally infected with B. bovis, phenotyped as CD4- (absence of anti-CD4 staining), CD4 + (intermediate staining) or CD4 ++ (high staining). The CD4 mRNA precursor was also measured in these animals. Calves with the CD4- phenotype showed higher amounts of B. bovis DNA in blood samples, compared to the other CD4 phenotypes. It was also observed that these calves with higher levels of infection had lower amounts of natural killer cells and higher expression of the CD4 gene, which can be interpreted as a compensation for the failure of the altered CD4 receptor to recognize relevant B. bovis epitopes.

Abstract
It is believed that increased livestock production is limited by tropical climate. Thermal imbalance in bulls can lead to hyperthermia and alter testicular metabolism, causing subfertility or infertility. Therefore, the thermoregulation of composite Canchim bulls (5/8 Charolais × 3/8 Zebu) raised in tropical climate as well as their consequences in the physiological, hematological, hormonal, and andrological parameters were evaluated monthly. The bulls (n = 18; 30.0 ± 1.5 months; 503.8 ± 23.0 kg) were kept on pasture, in a single group, from August 2015 to March 2016, comprising the winter, spring, and summer seasons. Biometeorological variables were continuously monitored, and the Temperature and Humidity Index (THI) was calculated. A greater thermal challenge occurred in spring and summer (THI ≥ 72.0). Nevertheless, the bulls exhibited normothermia (38.6 to 38.9 °C) in these seasons. The cortisol did not vary between seasons (7.0 vs. 8.7 vs. 6.8 ng/mL; P > 0.05) and remained within the physiological patterns. Independent of the seasons, stress leukogram was also not observed, refuting the incidence of acute or chronic thermal stress. It is noteworthy that T3 and testosterone increased (P < 0.0001, P < 0.05) in spring and summer, the time that coincides with the breeding season, when there is increased metabolic requirement from the bulls. The progressive thermal challenge increase did not affect the scrotal thermoregulatory capacity, and in general, scrotal temperature remained at 5.2 °C below the internal body temperature. In summer, there was a 5% reduction in the minor sperm defects (P < 0.05) and DNA fragmentation in 2.4% of spermatozoa, a compatible value for high fertility bulls. The results show that the studied composite bulls can be considered as climatically adapted and constitute a viable alternative to be used in production systems in a tropical climate, even if the breeding seasons occur during the most critical thermal condition periods of the year.

Abstract
The chicken (Gallus gallus) embryo has been used as a classic model system for developmental studies because of its easy accessibility for surgical manipulation during embryonic development. Sex determination in birds is chromosomally based (ZZ for males and ZW for females); however, the basic mechanism of sex determination is still unknown. Here, the dynamics of expression of candidate genes implicated in vertebrate sex determination and differentiation were studied during embryonic chicken gonadal development. Gene expression profiles were obtained before, during, and after gonadal sex differentiation in females and males for DMRT1, SOX3, SOX9, DAX1, SCII, HINTZ, HINTW, and the male hypermethylated (MHM) region. Transcripts for the HINTZ, DMRT1, DAX1, SCII, and SOX9 genes were observed in both sexes, but expression was higher in male gonads and may be correlated with testicular differentiation. The expression patterns of HINTW, SOX3, and MHM suggest that they may act in ovary development and may be involved in meiosis entry. MHM was upregulated and DMRT1 was downregulated in females at the same developmental stage. This may indicate a regulation of DMRT1 by MHM ncRNA. Similar dynamics were observed between HINTW and HINTZ. This study reports on the MHM expression profile during gonadal development and its correlation with the expression of genes involved in vertebrate sex determination.

Abstract
A interação genótipo-ambiente (IGA) foi estudada por meio de dois procedimentos distintos, em características produtivas e reprodutivas de bovinos da raça Nelore. Dados de pesos padronizados aos 120 (P120); 210 (P210); 450 (P450) dias de idade, perímetro escrotal aos 450 dias de idade (PE450) e idade ao primeiro parto (IPP), de 211.744 registros de animais Nelore, criados na região da Amazônia Legal, foram utilizados na análise. O efeito da IGA foi estudado por meio de estimativas de herdabilidade e de correlações entre classificações, comparando os animais da Amazônia Legal com a base geral de animais do PMGRN - Nelore Brasil. As análises bi-característica consideraram o P120 como característica-âncora, com P210; P450 e PE450. A característica IPP foi analisada separadamente, em análise de característica única e considerando como efeito fixo o GCIPP e como aleatórios os efeitos aditivos genético e residual. As estimativas de herdabilidade para P120; P210; P450; PE450 e IPP nos dados da Amazônia Legal foram: 0,20 a 0,49; 0,21; 0,48; 0,45 e 0,21, respectivamente, e nos dados gerais do PMGRN - Nelore Brasil foram: 0,23; 0,25; 0,34; 0,43 e 0,11, respectivamente. As correlações entre classificações de rank para P120; P210; P450; PE450 e IPP foram iguais a 0,77; 0,79; 0,82; 0,78 e 0,38, respectivamente. As análises da IGA, por meio das estimativas de herdabilidade, evidenciaram maiores efeitos sobre os aspectos maternos, de peso aos 450 dias de idade e idade ao primeiro parto, enquanto que as correlações entre classificações mostraram fortes evidências em quase todas as características estudadas.

Abstract
Parameters based on the probability of gene origin were used to describe genetic variability in three reproductive groups from the Breeding Program for Nellore Cattle (PMGRN). The three reproductive populations (cows in reproductive age, bulls from artificial insemination centers and young bulls in progeny test) generated medium to low values. The effective number of founders (Nf ), the effective number of ancestors (Na) and the remaining genomes (Ng) suggest low founder representativeness, high genetic contribution by some ancestors, considerable loss of founder alleles and lack of allelic representativeness in bulls kept in artificial insemination centers and young sires in progeny test in relation to the diversity on the farms participating in the PMGRN. The parameters based on the probability of gene origin in the three reproductive groups were: 84.3, 53 and 54.2 (Nf ); 71, 36.6 and 30 (Na) and 51.4, 19.3 and 19 (Ng) for cows, bulls from artificial insemination centers and young sires in progeny test, respectively. Future matings and the introduction of selected progeny reproduction may decrease the parameters based on the probability of gene origin in each reproductive group, thereby increasing considerably the additive relationship in the three reproductive groups and consequently increasing the probability of inbreeding in the future. Strategies to maintain genetic variability in bull populations must be implemented.

Abstract
Insulin-like growth factor II (IGF-II) is a polypeptide that plays a key role in mammalian growth, influencing fetal cell division, differentiation, and possibly metabolic regulation. In adult humans, polymorphisms of the IGF2 gene have been associated with predisposition to obesity. In the present study, we tested the association between IGF2/ApaI genotype and Body Mass Index (BMI) in 294 healthy volunteers (95 men and 199 women; 18-30y) and correlated the results with their birth weights (BW) in order to investigate the relationship between this polymorphic site, fetal life and adult BMI. Blood samples were obtained for DNA extraction, PCR and genotyping. The statistical analyses were performed by the Chi-square, Kolmogorov-Smirnov normality, and Tukey post hoc tests. Although the IGF2 genotype was not significantly associated with BMI and/or BW, we observed a statistically significant correlation of 0.33 (p < 0.023) between BW and BMI in GG subjects whose BW was higher than 3.5 kg (n = 47). We hypothesize that high BWs associated with homozygosis for the G allele of IGF2/ApaI is not a null factor and might be associated with predisposition to high BMI in young adults.
