Metals in the pathogenesis of type 2 diabetes

Area of Science:

• Biochemistry
• Human Physiology
• Nutritional Science

Background:

• Minerals are essential dietary components not synthesized by the body, crucial for numerous biochemical processes.
• Essential metals like zinc (Zn), magnesium (Mg), and manganese (Mn) act as cofactors for hundreds of enzymes.
• Zn is critical for insulin synthesis and secretion, while chromium (Cr) enhances insulin receptor activity.

Purpose of the Study:

• To review the critical roles of essential trace elements in maintaining normal physiological homeostasis.
• To explore how disruptions in essential trace element levels are linked to the pathobiology of type 2 diabetes.

Main Methods:

• Literature review focusing on the physiological functions of essential trace elements.
• Analysis of studies investigating the relationship between trace element status and glucose metabolism.
• Discussion of biochemical pathways involving minerals in insulin signaling and glucose regulation.

Main Results:

• Essential trace elements are indispensable for enzyme function, protein activity, and hormonal regulation, including insulin.
• Insulin deficiency or resistance leads to hyperglycemia, a hallmark of diabetes mellitus.
• Diabetes and poor glycemic control are associated with altered levels of essential trace elements (e.g., Zn, Mg, Mn, Cr, Fe) due to increased urinary excretion.

Conclusions:

• Essential trace elements play fundamental roles in maintaining metabolic balance and physiological function.
• Perturbations in essential trace element homeostasis are significantly implicated in the development and progression of type 2 diabetes.
• Maintaining adequate levels of essential trace elements is important for managing glycemic control and overall health in diabetic individuals.
