Abstract

Protegrin‑1 (PG‑1), a β‑hairpin antimicrobial peptide (AMP), is amongst the shortest AMPs in sequence length while remaining active against a variety of microorganisms. The aim of this study was produce recombinant PG‑1 and investigate its anticancer activity. A DNA sequence encoding the mature PG‑1, fused with a 6His‑tag, was cloned into the pPICZα‑A vector and transformed into Pichia pastoris. Expression was induced following culture for ~96 h with 1% methanol at 28˚C, and ~15.6 mg PG‑1 was expressed in 100 ml culture medium. Following purification using a Ni‑chelating Sepharose column, ~20 mg pure active PG‑1 was obtained from 500 ml culture broth supernatant. The expressed PG‑1/6His exhibited strong dose‑ and time‑dependent anticancer activity against HepG2 cells in vitro.
