PC12 cells treated with cisplatin were simultaneously exposed to quercetin and LLLT. We evaluated the effects of quercetin and LLLT on the expression of GAP-43 and Synapsin I genes through real-time PCR, cell viability using MTT assay, apoptosis induction via Annexin and dead assay, mitochondrial potential alterations using a mitopotential assay, and lactate dehydrogenase activity analysis in cells. Our findings revealed that cisplatin led to increased apoptosis, mitochondrial dysfunction, and LDH activity, while reducing cell viability and inhibiting the expression of GAP-43 and Synapsin I genes in both undifferentiated and differentiated PC12 cells. However, the application of quercetin and LLLT resulted in decreased apoptosis, mitochondrial potential alterations, and lactate dehydrogenase activity. We propose further investigation into the in vivo effects of quercetin and low-level laser therapy on cisplatin-induced peripheral neuropathy, as well as exploring the molecular relationship between quercetin and low-level laser therapy.Read More
