In recent years, there has been increasing global concern about the rising prevalence and rapid progression of psychosomatic disorders (PD). This surge can be attributed to irregular biological conditions and the increasingly stressful lifestyles that individuals lead, ultimately resulting in functional impairments of vital organs. PD arises from intricate interactions involving the central nervous, endocrine, and immune systems. Notably, the hypothalamic-pituitaryadrenal (HPA) axis plays an essential role, as its dysregulation is influenced by prolonged stress and psychological distress...

The endoplasmic reticulum (ER) is a sub-cellular organelle that is responsible for the correct folding of proteins, lipid biosynthesis, calcium storage, and various post-translational modifications. In the disturbance of ER functioning, unfolded or misfolded proteins accumulate inside the ER lumen and initiate downstream signaling called unfolded protein response (UPR). The UPR signaling pathway is involved in lipolysis, triacylglycerol synthesis, lipogenesis, the mevalonate pathway, and low-density lipoprotein receptor recycling...
