Fig 1. The analysis of CLOCK, IL1 and DUSP gene expression in the morning and evening during the months of Ramadan and Shabaan.

The expression levels of A)CLOCK, B)IL-1, and C)DUSP genes in the PBMCs of healthy volunteers (N = 23) in the morning (AM) and evening (PM) during Ramadan and Shabaan. Expression levels were normalized to housekeeping genes (β-actin and GADPH), and expressed as fold changes over the mean values of all subjects. Statistical analysis was performed using Student T test, values shown are mean ±SEM, *P<0.05 or **P<0.01.
