Effects of anaesthetic concentration of sevoflurane on TM3 mouse leydig cell viability / 中华麻醉学杂志

ABSTRACT

Objective To investigate the effects of anaesthetic concentration of sevoflurane on TM3 mouse leydig cell viability.Methods TM3 mouse leydig cells were randomly divided into 3 groups ( n =24 dishes each)control group (group C),2％ and 5％ sevoflurane groups (groups SEV1 and SEV2 ).The cells were collected after being exposed to sevoflurane or 95 ％ room air + 5 ％ CO2 for 2,4 or 6 h (T1-3) for microscopic examination with optical binocular inverted microscope.The number of live cells was counted by using cell counting kit8.Gene chips were used to indentify differentially expressed genes between group C and group SEV2 after being exposed to air and 5 ％ sevoflurane for 6 h respectively.Results The leydig cell viability was significantly decreased at T3 in group SEV2 as compared with groups C and SEV1.Morphological changes were found only in group SEV2.A total of 45 genes were identified to be differentially expressed in group SEV2 as compared with group C.The level of expression of prostaglandin-endoperoxidase synthase 2 gene (Ptgs2),chemokine (C-C motif) ligand 2(CCL2) gene and dual specificity phosphatase1 (Dusp1) gene increased by at least 4 times in group SEV2.Conclusion Sevoflurane can inhibit the cell viability of TM3 mouse leydig cell in concentration dependent manner through abnormal expression of Ptgs2,CCL2 and Dusp1 genes.
