Objective To study the mechanism of Wuzi Yanzong Wan (Five-Seed Progeny Pill) on im­proving heat stress resistance of Sertoli cells in rats based on data from the whole genome microarray. Methods Sertoli cells in primary culture were randomly divided into Wuzi Yanzong Wan (WZYZW) group, normal group and model group. The cells in three groups were given WZYZW solution and equal volume of PBS respectively. After 24 hours, rats in WZYZW group and model group were placed in water bath at 43 °C for 15 minutes, while rats in normal group were put in water bath at 37 °C for 15 minutes, then total RNA of three groups were extracted respectively and data was analyzed with gene chip technolo­gy. Results Compared with the model group, there were totally 1,203 differently genes in WZYZW group based on Sertoli cell gene expression profiles, in which 697 were down regulated and 506 were up-regulated. There were totally 473 differently expressed genes in the normal group, including 168 up-regu-later! genes and 305 down regulated genes. Among these down-regulated gene expressions. RGD1305298. Trptl, D113, Abi3 and Ppplrl2b were significant in the WZYZW group and norma! group, while Dusp7 was significant among up-regulated gene expressions. The genes mentioned above were related to cell cycle, apoptosis, cell metabolism, cell adhesion and Notch signal pathway, regula­tion of act in cytoskeleton, MAPK signaling pathway and tight junction pathway, etc. Conclusion The mechanism of Wuzi Yanzong pill in improving heat stress resistance of Sertoli cells may involve mainte­nance of tight junctions between Sertoli cells, inhibition of Sertoli cells apoptosis and promotion of cell dif­ferentiation and maturation.
