OBJECTIVE
Dipeptidyl peptidase-4 (DPP-4) inhibitors improve glycemic control in patients with type 2 diabetes mellitus. There are also reports of an effect of these drugs in reducing inflammation through inhibition of tumor necrosis factor-α (TNF-α) that is an important mediator for several
A Chlorella powder was tested in 118 in vitro enzyme assay systems. The powder showed potent inhibitions of peptidase cathepsin S, thromboxane A(2) synthase and cyclooxygenase-2 in a dose-concentration manner with IC(50)+/-standard error of the mean values of 3.46+/-0.93 microg/ml, 3.23+/-0.69
OBJECTIVE
To assess the enzymatic activity and biochemical status of dipeptidyl peptidase IV (DPP IV), an enzyme that participates in the degradation of proinflammatory molecules, in sera from a group of patients with rheumatoid arthritis (RA; n = 15) treated with a human anti-tumor necrosis
Tumour necrosis factor alpha (TNF α) leads to β cell damage in type 1 diabetes (T1DM) but also causes insulin resistance (IR). It modulates dipeptidyl peptidase-4 (DPP-4) activity, adipokine linked with both IR and T1DM. We were interested if there is an association of TNF α in conjunction with
Surface peptidase activities on the human monocytic lineage cell line U937 were characterized. Two diisopropyl phosphofluoridate (DFP)-inhibitable serine peptidases were identified by differences in their hydrolytic activities on chromogenic peptides: one removed tripeptides from the free
Ubiquitination and deubiquitination of receptor-interacting protein 1 (RIP1) play an important role in the positive and negative regulation of the tumor necrosis factor alpha (TNFalpha)-induced nuclear factor kappaB (NF-kappaB) activation. Using a combination of functional genomic and proteomic
BACKGROUND
The mechanism by which hypertriglyceridemia (HTG) leads to pancreatitis is not clear. We sought to determine whether the genes involved in pancreatic ductal or acinar cell injury, including the cationic trypsinogen gene [protease, serine, 1 (trypsin 1) (PRSS1)], the pancreatic secretory
OBJECTIVE
To seek differentially expressed serum proteins in recovered SARS patients complicating avascular necrosis of femoral head (AVNFH).
METHODS
2-DE and MALDI-TOF MS were used to study the comparative serum proteomics among female SARS AVNFH group, female SARS non-AVNFH group and female
BACKGROUND
The results of recent studies suggest that dipeptidyl-peptidase-4 inhibitors have antiatherogenic effects. However, whether or not dipeptidyl-peptidase-4 inhibitors could suppress arterial inflammation and intimal hyperplasia after injury remains undetermined. The present study aims to
We have studied the production of mouse tumor necrosis factor alpha (mTNF) with Streptomyces lividans as host. mTNF cDNA was fused to the alpha-amylase-encoding gene (aml) of Streptomyces venezuelae ATCC15068 at 12 amino acids (aa) downstream from the signal-peptidase cleavage site so that the aa
The potential atheroprotective effects of glucagon-like peptide-1 (GLP-1), long-acting GLP-1 analogues and inhibitors of the enzyme dipeptidyl peptidase 4 (DPP-4) are currently the subject of intense research. Recent evidence suggests the effects of DPP-IV inhibitors, may, in-part, be mediated by
Herein we describe four patients with acquired hemophilia A (AHA) caused by factor VIII (FVIII) inhibitor and histories of dipeptidyl peptidase-4 inhibitor (DPP4-I) treatment for diabetes mellitus (DM). Drug exposure can cause a breakdown of immune tolerance to FVIII associated with CD4 T cells,
Dipeptidyl peptidase IV (DPP IV) (CD26) plays a critical role in the modulation and expression of autoimmune and inflammatory diseases. We recently reported that sera from patients with rheumatoid arthritis and systemic lupus erythematosus contained low levels of DPP IV and high titers of anti-DPP
UV-sensitive syndrome is an autosomal recessive disorder characterized by hypersensitivity to UV light and deficiency in transcription-coupled nucleotide excision repair (TC-NER), a subpathway of nucleotide excision repair that rapidly removes transcription-blocking DNA damage. UV-sensitive syndrome
The production of human tumor necrosis factor beta (hTNF beta) in Streptomyces lividans was studied. The expression of hTNF beta uses the transcription, translation and secretion signals of subtilisin inhibitor VSI which is naturally produced by Streptomyces venezuelae CBS762.70. In direct secretory
