Summary
C-peptide, a proinsulin byproduct, promotes inflammation in atherosclerosis and diabetic complications. Elevated C-peptide levels in patients with insulin resistance and early type 2 diabetes are linked to vessel wall inflammation.
Area of Science:
- Biomedical Science
- Vascular Biology
- Endocrinology
Background:
- Atherosclerosis is an inflammatory condition linked to heart attack and stroke.
- C-peptide, a proinsulin cleavage product, exhibits biological activity affecting vascular complications in type 2 diabetes.
- Elevated C-peptide levels are observed in insulin resistance and early type 2 diabetes.
Purpose of the Study:
- To review recent findings on the proinflammatory effects of C-peptide.
- To explore C-peptide's role in vascular inflammation and diabetic complications.
Main Methods:
- Literature review of recently published studies.
- Analysis of research on C-peptide deposition in vessel walls.
- Examination of C-peptide's proliferative effects on mesangial cells.
Main Results:
- C-peptide has been found to deposit in the vessel wall of ApoE-deficient mice.
- C-peptide can induce local inflammation within the vessel wall.
- C-peptide demonstrates proliferative effects on human mesangial cells.
Conclusions:
- C-peptide contributes to local inflammation in the vessel wall.
- C-peptide's proinflammatory actions may exacerbate atherosclerosis and diabetic complications.
- Further research is warranted to fully elucidate C-peptide's role in vascular disease.

01:58Cell Specific Gene Expression
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...
01:21Acute Pancreatitis II: Pathophysiology
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
01:25Acute Inflammation III: Local and Systemic Effects
Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
01:25cAMP-dependent Protein Kinase Pathways
Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...
01:09GPCRs Regulate Adenylyl Cylase Activity
Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of cells.
