Potential anti-cancer effects of hibernating common carp (Cyprinus carpio) plasma on B16-F10 murine melanoma: In vitro and in vivo studies.

Melanoma is the major type of skin cancer, which its treatment is still a challenge in the world. In recent years, interest in hibernation-based therapeutic approaches for various biomedical applications has been increased. Many studies indicated that some factors in the blood plasma of hibernating animals such as alpha-2-macroglobulin (A2M) cause anti-proliferative effects. Considering that, the present study was conducted to investigate the anti-cancer effects of hibernating common carp plasma (HCCP) on murine melanoma (B16-F10) in vitro and in vivo. The effect of HCCP on cell viability, migration, apoptosis rate, and cell cycle distribution of B16-F10 cells, tumor growth, and rate of survival were evaluated. To investigate the role of A2M in the anti-cancer effects of HCCP, the gene of interest and proteins in HCCP and non-hibernating common carp plasma (NHCCP) were evaluated by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) assay as well as sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and mass spectrometry analysis. Based on our findings, HCCP significantly decreased B16-F10 cell viability. Moreover, HCCP caused morphological alternations, inhibition of migration, induction of apoptosis, and significantly induced the cell cycle arrest at the G2/M phase. In addition, A2M level was significantly increased in HCCP compared with NHCCP. Taken together, our findings suggested that HCCP had the potential to be a promising novel therapeutic target for cancer treatment because of its anti-cancer properties.
