[Primary Study on Chronic Myeloid Leukemia in NCG Mice from Qinba Mushroom].

Objective: The present study was to evaluate the anti-tumor effects of acidic RNA protein complex (FA-2-b-β) extracted from the wild edible Qinba mushroom in inducing of apoptosis and immunoregulation of tumor cell.

Methods: Cell proliferation inducing rate of FA-2-b-β to K562 cell was measured using CCK-8. Apoptosis rate was detected by using flow cytometry.

[Inhibitory Effects of Agaricus Blazei Murrill (FA-2-b-β) on Proliferation of Chronic Myeloid Leukemia Cells in vivo and Its Mechanism].

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 (r=0.
