Histone deacetylase 2-mediated deacetylation of the Ribonuclease 1 promoter in inflamed human endothelial cells [PDF]

, 2020
Endothelial cells (ECs) function as protective barrier to separate the blood from the surrounding tissue by conducting crucial roles in regulation and maintenance of vascular homeostasis, such as control of vessel permeability or coagulation.

Enhancement of the activity of the antimicrobial peptides HNP1 and LL-37 by bovine pancreatic ribonuclease A [version 3; peer review: 1 approved, 2 approved with reservations, 1 not approved]

F1000Research, 2023
Background: HNP1, LL-37, and HBD1 are antimicrobial against Escherichia coli ATCC 25922 at the standard inoculum but less active at higher inocula.   Methods: The virtual colony count (VCC) microbiological assay was adapted for high inocula and the ...

Intramolecular interactions in pancreatic ribonucleases [PDF]

Protein Science, 1992
AbstractA detailed analysis of the composition and properties of hydrophobic nuclei and microclusters in pancreatic ribonuclease A (RNase A) has been carried out. Distance calculations for all noncovalently bonded atoms revealed that the average number of nonpolar contacts between a side chain of an amino acid and its neighbors is substantially larger ...

Ultra-high resolution X-ray structure of orthorhombic bovine pancreatic Ribonuclease A at 100K

BMC Chemistry, 2023
The crystal structure of orthorhombic Bovine Pancreatic Ribonuclease A has been determined to 0.85 Å resolution using low temperature, 100 K, synchrotron X-ray data collected at 16000 keV (λ = 0.77 Å). This is the first ultra-high-resolution structure of

Human pancreatic ribonuclease 1 [PDF]

Cancer, 2000
Human pancreatic ribonuclease (RNase 1) is a pancreatic enzyme that is present at high levels in the serum of most patients with pancreatic adenocarcinoma. For this reason, the authors studied its patterns of expression at the single-cell level in pancreatic adenocarcinoma tissues by immunohistochemical analysis and in situ hybridization (ISH ...

A novel ligand-receptor relationship between families of ribonucleases and receptor tyrosine kinases

Journal of Biomedical Science, 2018
Pancreatic ribonuclease is known to participate in host defense system against pathogens, such as parasites, bacteria, and virus, which results in innate immune response. Nevertheless, its potential impact to host cells remains unclear.

Protein disulfide-isomerase interacts with a substrate protein at all stages along its folding pathway [PDF]

, 2014
In contrast to molecular chaperones that couple protein folding to ATP hydrolysis, protein disulfide-isomerase (PDI) catalyzes protein folding coupled to formation of disulfide bonds (oxidative folding).

A general approach to high-yield biosynthesis of chimeric RNAs bearing various types of functional small RNAs for broad applications. [PDF]

, 2015
RNA research and therapy relies primarily on synthetic RNAs. We employed recombinant RNA technology toward large-scale production of pre-miRNA agents in bacteria, but found the majority of target RNAs were not or negligibly expressed. We thus developed a

Study Levels of Some Biochemical Parameters in Serum of Pancreatic Cancer Patients

Tikrit Journal of Pure Science, 2018
This study included an estimation for the levels of some biochemical parameters in the serum of those pancreatic cancer patients, by collecting (40) blood samples from patients their ages ranged (30-70) years compared with (55) blood samples of healthy ...

Functional role of glutamine 28 and arginine 39 in double stranded RNA cleavage by human pancreatic ribonuclease. [PDF]

PLoS ONE, 2011
Human pancreatic ribonuclease (HPR), a member of RNase A superfamily, has a high activity on double stranded (ds) RNA. By virtue of this activity HPR appears to be involved in the host-defense against pathogenic viruses.
