The novel coronavirus, SARS-CoV-2, broken out as the COVID-19 epidemic, is transported into cytoplasm by angiotensin-converting enzyme-2 (ACE2), a key protein of renin-angiotensin-system (RAS). ACE2 protective that reduces angiotensin (Ang) II, bioactive component RAS, converting it to its potent antagonist, Ang-(1-7) peptide, in order provide pathophysiological response stimuli. Although ACE-2...

We describe a family with an apparently autosomal-dominant trait that caused extremely high circulating concentrations of the carboxyl-terminal propeptide of type I procollagen (PICP). All family members examined had normal values for other biochemical markers of bone formation and degradation and no related clinical abnormalities. Furthermore, their serum concentrations of the amino-terminal p...

OBJECTIVES As myocardial fibrosis might be an important contributor to the association of obesity with left ventricular (LV) dysfunction and heart failure, we investigated the effects of spironolactone on LV function and serological fibrosis markers (procollagen type III N-terminal propeptide (PIIINP) and procollagen type I C-terminal propeptide (PICP)) in patients with obesity and abnormal LV ...

The effect of chronic cardiac lymphatic obstruction on the myocardial synthesis of collagen type I and III was investigated in a rabbit model. In the lymphatic obstruction group (n=16), plasma C-terminal propeptide type I procollagen (PICP) and N-terminal propeptide type III procollagen (PIIINP) were elevated at 7, 14 and 30 days after the operation (p<0.05). The elevated PICP and PIIINP return...

The propeptides PICP and PINP are derived from the synthesis of type I collagen, a major matrix protein of bone and soft tissues. The aim of this cross-sectional study was to investigate their value as indicators of the aggressivity of breast cancer. Serum PINP, PICP, and total alkaline phosphatase were determined from 89 breast cancer patients. Forty had major bone and/or soft tissue metastase...

Abstract A key hallmark of Alzheimer’s disease is the extracellular deposition amyloid plaques composed primarily amyloidogenic amyloid-β (Aβ) peptide. The Aβ peptide a product sequential cleavage Amyloid Precursor Protein, first step which gives rise to C-terminal Fragment (C99). Cleavage C99 by γ-secretase activity releases several lengths and Aβ42 isoform in particular has been identified as...

A tetracosapeptide (peptide-24) corresponding to the amino-terminal sequence of the carcinoembryonic antigen (CEA) was synthesized and characterized. Antisera were produced to the peptide-24, and a radioimmunoassay was developed utilizing peptide-24 with a tyrosine residue on the amino-terminal end (Tyr-peptide-24). Inhibitions of anti-peptide-24-125I-Tyr-peptide-24 complex formation were done ...

Antimicrobial resistance (AMR) is on the rise, leading to 700 000 deaths worldwide in 2020. peptides (AMPs) are antibiotic agents that active against multi-drug resistant pathogens and also have a reduced risk of AMR development. Previous studies shown dimerisation proline-rich antibacterial peptide (PrAMP) Chex1–Arg20 can enhance its antimicrobial activity while reducing toxicity. To determine...
