Zusammenfassung: | To investigate the antitumor effects of human placenta hydrolysate (HPH) peptides on three hormone-dependent human cell lines: prostate adenocarcinoma, breast carcinoma, and ovarian cancer by metabolic analysis of cell cultures.
The effect of HPH on tumor and control tumor cell lines was evaluated. Study stages: (A)
peptide sequencing by collision-induced dissociation mass spectrometry; (B) detection of peptides with anti-tumor properties; (C) expert analysis of the obtained lists of peptides.
Dose-dependent cytotoxic effects of HPH on three tumor cell lines are shown: PC-3 (human prostate adenocarcinomas), OAW-42 (human ovarian cancer), BT-474 (human breast carcinomas), and IC
constants (1.3-2.8 mg/ml) were obtained. The analysis of the HPH peptide fraction showed more than 70 peptides with antitumor properties in the composition of this HPH, including kinase inhibitors: mitogen-activated protein kinases, kappa-bi nuclear factor inhibitor kinase, AKT serine/threonine kinase 1, protein kinase C zeta, interleukin-1 receptor-associated kinase 4 and cyclin-dependent kinase 1.
The results of the study indicate not only the oncological safety of the HPH used in therapy but also the mild antitumor effects of this HPH at high concentrations. |
