PBM modulate PARs genes expression in DPSCs. Real-time quantitative PCR (qRT-PCR) analysis of gene expression in LPS stimulated DPSCs irradiated with the infrared wavelength (808 nm) with total energy of 6 J (100mW × 60s). The bars represent the mean expression levels of the four PARs genes and standard error. The qRT-PCR analysis of gene expressions was normalized to the housekeeping gene enzyme β-2-microglobulin for DPSCs (control); the relative quantification of the expression levels (experimental/control) was determined based on the 2-ΔCt method. Experiments were performed in triplicate. Different letters indicate statistically significant differences (p < 0.05) in gene expression.
