Abstract

OBJECTIVE: To explore whether Arctigenin-Valine ester (ARG-V) can treat myelosuppression caused by chemotherapy.

METHODS: The number of peripheral blood cells of the mice was measured by an automatic blood analyzer, and the hematopoietic progenitor colonies CFU-GM, CFU-E, BFU-E, and CFU-Meg were cultured in vitro. Hematopoietic progenitor colonies and BMNCs were counted under an inverted microscope. The expressions of cytokines GM-CSF, EPO and TPO were detected by ELISA. The cell cycle was measured by flow cytometry. The expressions of related proteins MEK and p-ERK were quantitated by western blots, and the thymus index and spleen index were quantitated.

RESULTS: After taking ARG-V, the peripheral blood cells of the mice gradually returned to normal, the number of nucleated cells in the bone marrow increased, the thymus index increased, the spleen index decreased, the number of hematopoietic progenitor cells increased, and the hematopoietic cytokines decreased. And ARG-V promoted the transformation of myelosuppression cells from G0/G1 to S and from S to G2/M. ARG-V could up-regulate the expression of MEK and p-ERK, and low dose ARG-V is not as effective in all aspects as high dose ARG-V.

CONCLUSION: ARG-V can effectively alleviate the myelosuppression that caused by intraperitoneal injection of CTX in 100mg/kg, and ARG-V can promote the proliferation and differentiation of hematopoietic progenitor cells and improve immunity, and the effect of high-dose Arctigenin-Valine ester is more significant to some extent.
