Detection of miRNA-15a, miRNA-29b, miRNA-34a and miRNA-223 in Cow, Sheep, Goat, Buffalo, and Donkey Milk and Investigation of Their Relationship with Milk Composition
Abstract
The objective of this study was to ascertain the expression levels of miRNA-15a, miRNA-29b,
miRNA-34a, and miRNA-223 in milk from cows, buffaloes, sheep, goats, and donkeys and to examine their
relationship with milk composition. The miRNA expression levels were quantified by RT-qPCR, and their correlation
with the physicochemical data of the milk was examined. The expression of miRNAs was observed in
all milk samples and there was a correlation between miRNA expression and milk fat, protein, dry matter and
pH. A positive correlation was observed between fat and miRNA-34a in cows’milk, a positive correlation between
fat and miRNA-29b in donkey milk (P<0.05), and a negative and significant correlation between fat and
miRNA-29b in sheep milk (P<0.05). A positive and significant correlation was identified between dry matter
and miRNA-34a in sheep milk (P<0.05), whereas a negative and significant correlation was observed between
dry matter and miRNA-223 in goat milk (P<0.05). Additionally, a negative and significant correlation was found
between dry matter and miRNA-29b in sheeps’milk (P<0.05). A positive and significant relation ship was identified
between miRNA-34a expression and pH in sheep milk (P<0.05). It can be concluded that miRNAs play an
important role in milk composition, hygiene, health and technology. Further studies are recommended to gain a
deeper understanding of these aspects.
