摘要

This study investigated the in vitro antioxidant, proapoptotic and anti-proliferative activity of phycocyanin extracted from Ulva lactuca (Chlorophyta) algae extract loaded on albumin nanoparticle (ULANP). The characterization of ULANP profile was done by using FTIR and its cytotoxicity was investigated by using MTT assay against HepG2 and MCF7 cell lines. The proapoptotic markers caspase 8 & 9 were measured. Analysis of ULANP by FTIR showed the characteristic band (2100 cm-1 ~3700 cm-1) that is indicated primarily by -COO, -CO and conjugated double bond. These bonds showed the spectral band at peaks of 2985 cm-1 and 2860 cm-1, 2986 cm-1 respectively. The antioxidant potential and radical scavenging property of ULANP was also appreciable as compared to the vitamin C and gallic acid. The antiproliferative assay carried out by WST-1 suggests that ULANP was effective against both HepG2 (93.17%) and MCF7 (91.3%). Caspase-8 and -9 were significantly elevated (p < 0.001) in both the cell lines of breast and liver cancer. It was concluded that ULANP induced anti-proliferative and pro-apoptotic activities on liver and breast cancer. It is promising as a novel antitumor activity for further investigation the mechanistic pathways mediated this action.
