بررسی خاصیت سمیت سلولی زهر عروس دریایی گونه Chrysaora hysoscella علیه سلولهای سرطانی کولون انسانی.

Jellyfish venom contains a variety of compounds including several potential therapeutic properties. The present study investigates the venom of Chrysaora hysoscella jellyfish and analyzes its cytotoxic properties. The fractions of C. hysoscella jellyfish venom were purified using HPLC method, and their molecular weight was determined by SDS-PAGE method. The cytotoxic properties of the fractions were evaluated using the MTT method against HCT116 and Caco-2 cancer cell lines as well as RAW 264.7 normal cells. Based on the obtained results, the raw venom of C. hysoscella had 10 fractions with a molecular weight of 15 to 170 kilodaltons, of which fraction 2 had a strong cytotoxic effect against the studied cancer cell lines. The value of IC₅₀ against HCT116 and Caco-2 cells was 63.21 and 64.36 μg/mL, respectively, while against RAW 264.7 cells, it was 122.88 μg/mL. The obtained results revealed the specific cytotoxic property of fraction 2 against colon cancer cells, while its cytotoxic effect on normal cells was significantly less. These results introduce the fraction 2 as a potential anticancer agent for colon cancer [ABSTRACT FROM AUTHOR]
