Abstract:

Objective: To study the inhibitory effect of bioactive peptide derived from oyster meat Guangxi region,
China on the proliferation and migration of human ovarian carcinoma cells with directional high lymphatic metastasis
(SKOV3-PM4 cells). Methods: The 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay
was performed to study the inhibitory effect of the bioactive peptide on cell proliferation in 24 h. The proliferative ability
of SKOV3-PM4 cells was detected by cell counting method and colony formation test. The ability of cell migration and
invasion was examined by cell wound scratch assay and matrigel invasion assay. Results: MTT results showed that the
bioactive peptide could inhibit the proliferation of SKOV3-PM4 within the concentration range of 5?80 mg/L and that half
inhibition concentration (IC50) in 24 hours was 35.36 mg/L. The cell growth curve and cell colony formation showed that
the proliferative ability of SKOV3-PM4 cells was significantly inhibited (P < 0.05). Compared with control cells, after
being treated with 4 mg/L (non-cytotoxic concentration) the bioactive peptide, the migration and invasion capability of
SKOV3-PM4 was also significantly decreased (P < 0.05). Conclusion: The bioactive peptide derived from oyster from
Guangxi region can inhibit the proliferation and migration of SKOV3-PM4 cells within a certain concentration range.

Key words: bioactive peptide derived from oyster, ovarian cancer, lymphatic metastasis, cell migration
