Implication

Review uncovers bidirectional links between circadian rhythm disruptions and insulin resistance in biological systems, highlighting molecular pathways driving type 2 diabetes.

Key Points

  • To systematically examine the bidirectional biological mechanisms linking circadian rhythm dysregulation with the onset and progression of insulin resistance.
  • Reviewed published molecular and physiological studies investigating the interplay between circadian clock machinery and insulin signaling pathways.
  • Evaluated the roles of core clock genes (CLOCK, BMAL1, PER, CRY) and hormonal variations alongside melatonin receptor (MTNR1B) expression.
  • Circadian disruption alters core clock gene oscillations and hormonal rhythms, leading to impaired insulin sensitivity and compromised glucose regulation.
  • Insulin resistance reciprocally disturbs circadian rhythm function by modifying the expression of melatonin receptors and clock-controlled genes, exacerbating metabolic dysfunction.
