Wound healing potential: evaluation of molecular profiling and amplification of Lucilia sericata angiopoietin-1 mRNA mid-part.

ABSTRACT

OBJECTIVE: High prevalence of chronic ulcers and the burden of disease necessitate the increasingly significant production of new recombinant proteins in the world. The angiopoietin-1 enzyme is a part of the growth factors group which is secreted by Lucilia sericata (Diptera Calliphoridae) larvae when they meet lesions to ensure maggot therapy. It is one of the most potent proteins in wound healing. Given its essential role, the angiopoietin-1 gene of L. sericata was characterized, which provided some necessary information on its identity. RESULTS: The mid-part of the angiopoietin-1 mRNA sequence was thus characterized based on the design of different primers such as exon-exon junction, conserved regions, and specific region primers via conventional polymerase chain reaction (PCR). Its structural features were configured by in silico method. The sequence of mid-part (390 bp) of angiopoietin-1 was determined empirically, and BLAST analysis unraveled its high identity (85%) with the sequence of angiopoietin-1 mRNA of the larval housefly, Musca domestica. The homology of this enzyme also exhibited that its nucleic acid sequence was very similar to the domains of angiopoietin-1 in Lucilia cuprina. The current data are instructive and critical to evaluate the action of this enzyme in recombinant protein production in future molecular studies on wound healing.
