[Diagnostics value and regulatory functions of roinsulin.]

Area of Science:

• Endocrinology
• Metabolic Research
• Neuroscience

Background:

• Proinsulin is a key indicator of pancreatic islet cell function.
• An elevated proinsulin to insulin ratio is observed in insulin-independent diabetes mellitus.
• Hyperproinsulinemia, or elevated proinsulin levels, warrants further investigation into its causes and implications.

Purpose of the Study:

• To review the causes of hyperproinsulinemia.
• To evaluate the diagnostic utility of proinsulin in patients with type 1 and type 2 diabetes mellitus.
• To discuss the broader roles of proinsulin in cellular function and potential therapeutic applications.

Main Methods:

• Literature review of studies on proinsulin, hyperproinsulinemia, and diabetes mellitus.
• Analysis of the role of proinsulin in metabolic regulation and cellular preservation.
• Examination of research on proinsulin's neuroprotective and therapeutic potential.

Main Results:

• Hyperproinsulinemia is linked to pancreatic dysfunction and specific diabetes types.
• Proinsulin plays a role in metabolic pathways and cellular health across physiological and pathological states.
• Emerging evidence suggests proinsulin possesses neuroprotective properties.

Conclusions:

• Proinsulin's multifaceted roles justify its classification within the signaling factor superfamily.
• Proinsulin holds potential as a therapeutic agent for neurodegenerative diseases and retinal dystrophy.
• Further research into proinsulin's functions can enhance diabetes diagnostics and uncover novel therapeutic strategies.
