Objective To investigate the expression of ClC-2 chloride channels in rat trabecular meshwork as well as possible role of ClC-2 in onset mechanism of glaucoma. Methods Rat model of chronic high intraocular pressure was established by injecting sodium hyaluronate into anterior chamber. The trabecular meshwork tissues of normal and model rats were isolated, in which the transcription level of ClC-2 mRNA was determined by RT-PCR, and the expression level of ClC-2 protein by immunohistochemical method. Results The transcription of ClC-2 mRNA and expression of ClC-2 protein were observed in the trabecular meshwork tissues of both normal and model rats, while the transcription and expression levels in model rats were lower than those in normal rats. Conclusion The expression of ClC-2 chloride channels was proved in rat trabecular meshwork, which was influenced by some pathological factors of trabecular meshwork. LA: Chinese
