Effects of Formaldehyde on Protein Expressions of GluR2 and GABAR in Postnatal Rat Cortex Neurons in Culture / 环境与健康杂志

ABSTRACT

Objective To know the mechanism of the adverse effect of formaldehyde on cortex neurons. Methods In the present study, incubation of postnatal Wistar rat cortex neurons in culture with formaldehyde at 1.0, 2.0, 4.0, 8.0 mg/L (medium) was carried out to have knowledge of the effect of formaldehyde on the expressions of GluR2 and GABAR. For keeping the given concentration of formaldehyde, formaldehyde was added to the medium every hour for 4 consecutive hours. Results Immunocytochemistry showed a significant down-regulation of GluR2 and up-regulation of GABAR after 4 consecutive hours of formaldehyde treatment compared with the control (P
