Diabetes-induced Proteome Changes Throughout Development

Area of Science:

• Endocrinology
• Metabolic Diseases
• Molecular Biology

Background:

• Diabetes Mellitus (DM) is a complex endocrine disorder affecting insulin secretion by pancreatic beta cells.
• DM is associated with significant comorbidities, including hypertension, renal disease, and microvascular complications.
• The disease disrupts glucose homeostasis, impacting multiple organ systems.

Purpose of the Study:

• To review the molecular underpinnings of glucose homeostasis disruption in DM.
• To explore the links between pancreatic, renal, and microvascular pathologies in DM.
• To highlight the roles of oxidative stress and the Unfolded Protein Response (UPR) in DM pathogenesis.

Main Methods:

• This review synthesizes current research on the molecular mechanisms of DM.
• It examines the interplay between genetic and environmental factors in DM development.
• Focuses on biomolecular changes related to glucose metabolism and associated diseases.

Main Results:

• Type 1 DM involves autoimmune beta-cell destruction, while Type 2 DM features insulin resistance and beta-cell overload.
• Both types result in insulin deficiency, with Type 2 also involving insulin resistance.
• Oxidative stress and UPR are identified as central molecular links connecting pancreatic, renal, and microvascular damage in DM.

Conclusions:

• Understanding the molecular basis of DM, including proteome changes, is crucial for advancing therapeutic strategies.
• Targeting oxidative stress and UPR pathways may offer novel treatment avenues for DM and its complications.
• Further research into proteomic alterations can lead to more effective and personalized diabetes management.
