Abstract:
Objective To establish a cell line with overexpression of rat serotonin1A receptor (5-HT1AR).Methods Human neuroblastoma cells-SH-SY5Y were donated by cancer institute attached to the 4 th Affiliated Hospital, Hebei Medical University. Total RNA was extracted from brain tissues of male SD rats and rat 5-HT1A R was obtained by RT-PCR. Plasmid pc-DNA3. 1/hisC containing the rat 5-HT1AR (pc-DNA3.1/hisC-Rat-5-HT1AR)was constructed and transfected into SH-SY5Y cells. The transfected cells were isolated by G418 selection and SH-SY5Y-Rat-5-HT1A R cells were obtained. Expression of 5-HT1A R was detected by Western blot analysis. Cell viability was evaluated by MTT assay. SH-SY5Y-Rat-5-HT1AR cells were further observed for 5-HT1AR by immuno-fluorescence staining. Results Plasmid pc-DNA3. 1/hisC-Rat-5-HT1AR was successfully constructed by linking Rat-5-HT1A R with pc-DNA3.1/hisC and transfected into SH-SY5Y. The SH-SY5Y-Rat-5-HT1A R cells were more slender than SH-SY5Y cells with less and longer processes. MTT showed that the viability of SH-SY5Y-Rat-5-HT1A R cells was much lower than SH-SY5Y. Rat 5-HT1A R was expressed efficiently on the membrane of SH-SY5Y-Rat-5-HT1A R cells. Conclusion A cell line with overexpress of rat 5-HT1A R is successfully established.
