[PMID: 38981196 DOI: 10.1016/j.anireprosci.2024.107544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 06/24/2024] [Accepted: 06/27/2024] [Indexed: 07/11/2024]
Abstract
The Protein Phosphatase 6 Catalytic Subunit (PPP6C) is evolutionarily a conserved gene in eukaryotes known to play a significant role in mammalian reproduction. This study aimed to investigate expression patterns of PPP6C and explore its association with litter size in Shaanbei white cashmere (SBWC) goats. Initially, we determined the mRNA expression levels of PPP6C in both male and female goats across multiple tissues. The results showed that PPP6C mRNA was expressed in multiple tissues, with higher levels in the testis and fallopian tubes, suggesting its involvement in goat reproduction. Additionally, we identified a novel 19 bp InDel within the PPP6C gene in a population of 1030 SBWC goats, which exhibited polymorphism. Statistical analysis revealed a significant association between the19 bp InDel mutation and litter size (P < 0.05). Subsequent, bioinformatics analysis, including linkage disequilibrium (LD) block and selective scanning, highlighted the linkage tendency among most InDel loci did not stand out within B-8 block, there were still some InDel loci linked to the 19 bp within a relatively narrow region. Furthermore, comparative analysis with Bezoars, these selective signals all indicated that this gene was under higher selection pressure, implying that the 19 bp InDel locus within the PPP6C is potentially associated with domesticated traits, particularly in relation to litter size. The results of the present study suggest that the PPP6C is a vital candidate gene affecting prolificacy in goats, with implications for selective breeding programs for goat breeds.

Abstract
SMAD family member 2 (SMAD2) is a member of the TGFβ signaling pathway and functions as an essential regulator in the processes of development, cell proliferation, and bone formation. A previous observation reported that a 12-bp deletion of this gene affected the litter size in goats. However, according to our knowledge, no study has reported an association between this polymorphism and goat body measurement traits. The purpose of this study was to investigate the association of the insertion/deletion (indel) within the SMAD2 gene with the growth traits of goats. The indel polymorphism was found to be significantly associated with chest width and bust (p < 0.05), while cannon circumference was significantly the strongest compared to other traits (p < 0.01) and individuals with the DD genotypes were more dominant genotypes than other genotypes. In summary, we found evidence that the 12-bp indel within the SMAD2 gene could improve goat body measurement traits, paving the way for marker-assisted selection in the field of goat genetics and breeding.
