The expression of mucin genes and the presence of mucin gene products in the equine endometrium.

The research investigates the expression of mucin genes and their role in the reproductive tract of horses. The study contributes to better understanding of these genes and their effects on host-cell interactions and barrier function.

Objective of the Study

• The aim of the research was to identify the equine equivalents of mammalian mucin genes utilizing available horse sequence data.
• The study sought to profile the expression of these genes in the horse endometrium using reverse transcriptase polymerase chain reaction (RT-PCR).
• The research aimed to find the spatial expression patterns of mucin genes with the help of in situ hybridization.
• The presence of mucin gene products was confirmed through Western blotting and horse-specific mucin antibodies during oestrus and dioestrus.

Findings of the Study

• The study found that the pattern of mucin gene expression in the horse endometrium is similar to that in other mammals.
• However, it also found that several mucins appear to be uniquely expressed in this tissue, specifically eqMUC3B, 7, 18, and 20.
• Notably, one of these mucins, eqMUC3B, was found to be hormonally regulated.

Significance of the Findings

• The findings contribute to a broader understanding of the role and behaviour of mucin genes in equine reproductive health.
• Understanding how these genes behave provides deeper insights into horse breeding and genetic vulnerabilities of horses in relation to their reproductive processes.
• The identification of hormonally regulated mucins could have implications for manipulating or improving equine reproductive functions in the future.
