Then rAAV-DJ-1 was transfected into HEK-293 cells for packaging. AAV vectors encoding human DJ-1 protein were stereotactically injected into the rat SN 4 weeks prior to rotenone lesion in SN. Tyrosine hydroxylase protein was determined using immunohistochemical staining. Ethovison software allowed measurement of movement distance in 30 minutes.

As a member of POU transcription factor family, Oct-4 plays an important role in mammalian early embryonic development and takes part in maintenance of cellular totipotence and undifferentiated state.

Oct-4属POU家族蛋白，是一类在动物早期胚胎发育过程中起重要作用的转录因子，参与维持细胞的全能性及未分化状态。

And 37. 1%, respectively. The results suggest that 18α-GA down-regulated CYP expression at the transcriptive levels.

表明GL在转录水平下调大鼠肝细胞CYP1A1，CYP2E1和3A1表达，以对CYP2E1的抑制作用最强，对CYP3A的抑制作用最弱，对CYP1A1的抑制作用居中，与整体动物的酶学实验结果基本一致。

T739 mice were inoculated with LA795 cells. Angiostatin was given to part of inoculated and uninoculated mice by intraperitoneal injection fourteen days after the inoculation. The treatment lasted 20 days and the size of tumor, survival period, behavior of the mice and pathology of lungs, livers and kidneys were observed.
