[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.

extract (FA-2-b-β) induces apoptosis in chronic myeloid leukemia cells.

(AbM) is a mushroom belonging to the Basidiomycetes family, which is believed to have antitumor and antioxidative activities. Proteoglycans and ergosterol are considered the key compounds of AbM for antitumor properties and so are used in complementary and alternative medicine as an anticancer drug. AbM is used to avoid serious side effects that would inevitably affect patients.
