904 nm Low-Level Laser Irradiation Decreases Expression of Catabolism-Related Genes in White Adipose Tissue of Wistar Rats
Study Overview
Description: This study investigated the metabolic effects of photobiomodulation (PBM) on rat adipose tissue and evaluated the role of 904 nm low-level laser irradiation on the expression of catabolism-related genes in white adipose tissue.
Intervention: The rats were divided into four groups: a control group (CTL), a laser-treated group [CTL (L)], a caffeine group (CAF), and a caffeine + PBM group [CAF (L)].
Methods: Blood was extracted to quantify triglyceride and cholesterol levels, and white adipose tissue was collected for gene expression analysis of leptin receptor, hormone-sensitive lipase, tumor necrosis factor alpha, and beta-adrenergic receptor.
Conclusion: he study demonstrated that 904 nm low-level laser irradiation was able to increase the food intake of the animals and the relative mass of adipose tissue in the CTL (L) group. It also decreased the expression of catabolism-related genes in white adipose tissue.
