OBJECTIVE: To investigated the anti-tumor in vivo effect and mechanism of the acid RNA protein complex (FA-2-b-β) of Agaricus blazei Murrill extract.
METHODS: CCK-8 method was used to detected the inhibitory effect of FA-2-b-β on proliferation of primary CML cells from newly diagnosed CML patients, the CML mouse model was established by trail-venous injection of primary CML cells, and the survival time, blood cell count and body weight were observed, the immunoflouresence and immunehistochemistry analysis, RT-qPCR, Western bolt were used to detemine the expression of caspase-3 signal pathway-related apoptosis genes and proteins.
RESULTS: The experiments in vitro showed that the proliferative inhibitory rate in drug-treated group increased with concentration- and time-dependent manner (r24=0.9092, r48=0.9442, r72=0.9546), the inter group comparison showed the statistical difference of results. The experiments in vitro showed that the survival time prolonged, blood cell count increased and body weight recovered in FA-2-b-β-treated group and imatinib-treated group, despite the WBC count is still high. The RT-qPCR and Western blot showed that the expression of BAX and caspase-3 gene and protein were up-regulated, the expression of BCL-2, cytochroime C, caspase-8, caspase-9 and BCL-ABL gene and protein were down-regulated.
CONCLUSION: The FA-2-b-β can induce apoptosis of primary CML cells and prolong the survival time of CML model mouse, which may be related with the caspase-3 signal pathway related genes and proteins.
