The enterocytic differentiation of Caco-2 cells, a human colon adenocarcinoma cell line, is accompanied by the transcriptionally regulated expression of a subset of proteins and their correct sorting towards the cell surface. In the present work we have explored the possibility that post-translational events may interfere with this process by investigating the short term effects of a potent ade...

BACKGROUND Dipeptidyl peptidase-4 inhibitors are a class of oral hypoglycemic drugs and are used widely to treat type 2 diabetes mellitus in many countries. Adverse effects include nasopharyngitis, headache, elevated serum pancreatic enzymes, and gastrointestinal symptoms. In addition, a few cases of interstitial pneumonia associated with their use have been reported in the Japanese literature....

Streptococcus gordonii is generally considered a benign inhabitant of the oral microflora, and yet it is a primary etiological agent in the development of subacute bacterial endocarditis (SBE), an inflammatory state that propagates thrombus formation and tissue damage on the surface of heart valves. Strain FSS2 produced several extracellular aminopeptidase and fibrinogen-degrading activities du...

Title:Intraindividual changes of dipeptidyl peptidase-IV in peripheral blood of patients with rheumatoid arthritis are associated with the disease activity

SEE PAGE 573 A n association between diabetes and the risk of heart failure has been seen in observational studies. The mechanism is undefined, and it remains unclear whether dipeptidyl peptidase (DPP)-4 this association is related to concomitantmedical problems associated with diabetes (e.g., ischemic heart disease, renal dysfunction, hypertension) or the direct effect of poorly controlled blo...

In the United States, nearly 13% of adults aged 20 years and older have type 2 diabetes mellitus (T2DM), and its prevalence is still increasing (1,2). Microvascular and macrovascular abnormalities are common in patients with T2DM and are related to the severity and duration of hyperglycemia (3–5). Thus, treatment of hyperglycemia is an important way to prevent or delay diabetic vascular complic...

Methods were developed for the determination of oligoalanine and other short-chain peptides and peptide analogs in ruminal fluid by using reverse-phase high-pressure liquid chromatography. Chromatographic analysis of the breakdown of (Ala)3 and (Ala)4 in ruminal fluid in vitro revealed that the predominant mechanism of hydrolysis was a dipeptidyl peptidase-like activity. Hydrolysis proceeded fr...

The present review focuses initially on experimental studies that were designed to identify acid inhibitory factors, referred to as 'enterogastrones,' that ultimately led to the isolation of gastric inhibitory polypeptide (GIP), a 42-amino acid polypeptide. GIP was shown to inhibit acid secretion in animal models, as well as stimulating gastric somatostatin secretion. However, its role in human...
