Abstract
AbstractObjectiveA total of 205 animals from four Egyptian livestock species; cattle (n = 18), buffaloes (n = 12), sheep (n = 150) and goats (n = 25) were used in this study to detect polymorphism and perform comparative analysis for IGFBP-3 gene using DNA sequencing and (PCR–RFLP).ResultsThe amplified fragments were found to be of length 654 bp in sheep, 651 bp in cattle and 655 bp in buffalo. For Falahy goats, PCR was performed to amplify a 316 bp fragment from exon 2 of the IGFBP-3 gene. The digestion of 654 bp withHaeIIIrestriction enzyme yielded a single restriction pattern for goats, while for cattle, 3 genotypes were identified; (AA), (AB), and (BB). Moreover, for buffalo one genotype (AA) only was found withHaeIIIandTaqIrestriction enzymes, separately. Also, the digestion profile for goats withHaeIIIrevealed one pattern only. Nucleotide sequencing of the amplified fragments of IGFBP-3 gene in sheep, cattle, buffalo, and goat was submitted to the NCBI GenBank (Accession no. MG738671.1, MG738673.1, MG738674.1, and MG738672.1, respectively). The nucleotide sequencing analysis indicated similarity percentages in IGFBP-3 gene fragments of 88.54, 89.63 and 95.06% between “sheep and cattle”, “sheep and buffalo”, and “cattle and buffalo”, respectively.
