其他摘要：BACKGROUND: Phosphoinositide 3-kinase (PI3K) plays an important role in cellular proliferation and tumor progression. The objective of this study is to evaluate the potential mechanism and therapeutic effects of new PI3K inhibitor SHBM1009 on various cancer cells of digestive system on proliferation. METHODS: Six human hepatocellular carcinoma cell lines including 97H, 97L, A3, F11, MHCC-1, SMMC7721, one gastric cell line SGC-7901 and three primary testicular cancer TYST,TYST1,TYST2 cells were treated by 100ng/ml epidermal growth factor with or without 1uM NVP-BEZ-235 and SHBM1009 in Cell-IQ system in 24-well plates for 48h and up to 72h. The cell bio-behaviors, especially for cell proliferation of total cell number were measured by a real-time cell monitoring system, Cell-IQ continuous cell culturing platform. Images were captured at 30 min intervals. Cell-IQ system uses machine vision technology for monitoring and recording time-lapse data, and the cell functions and morphological parameters were quantified and analyzed. RESULTS: SHBM1009 could prevent EGF-induced cancer cells proliferation. Different patterns of inhibitory effects of SHBM1009 and NVP-BEZ-235, a dual PI3K/mechanistic target of rapamycin inhibitor, on EGF-induced cancer cells proliferation were observed. CONCLUSIONS: PI3K plays a critical role in the development of cancer progress, including proliferation, differentiation and anti-apoptosis. SHBM1009, a new PI3K inhibitor, could be new therapeutic alternatives for cancer treatment.
