摘要

Objective: To study the antitoxic role of vesicular monoamine transporter 2 (VMAT_2) in transgenic Chinese Hamster ovary (CHO) cell. Methods: With the technology of trans-gene from PC 12 to CHO, MTT reduction assay was used to detect MPP~+ toxic effect on wild type CHO (wtCHO) and transgenic CHO. Meanwhile, the role of reserpine was also observed in MPP~+ toxic effects. Results: The sensitivity of transgenic CHO to MPP~+ was much less than that of wtCHO with 0. 5 mmol/L MPP~+. Transgenic CHO had the same sensitivity as wtCHO if rotenone was given. WtCHO, by given reserpine alone, didn't change its sensitivity to MPP~+. Conclusions: VMAT_2 has protective effect on transgenic CHO by transporting MPP~+ to vesicles.
