Associations of Neprilysin and Its Coding Gene Variation With Hypertension in Chinese Adults

open access: yesThe Journal of Clinical Hypertension, Volume 28, Issue 4, April 2026.
ABSTRACT Neprilysin (NEP) degrades several vasoactive peptides and may contribute to blood pressure maintenance. This study aims to examine the associations between serum NEP levels and variants at its coding gene and hypertension in a general Chinese population.

Chloroplast Proteins without Cleavable Transit Peptides [PDF]

open access: yes, 2009
Most chloroplast proteins (cp proteins) are nucleus-encoded, synthesized on cytosolic ribosomes as precursor proteins containing a presequence (cTP), and post-translationally imported via the Tic/Toc complex into the organelle, where the cTP is removed ...

Differential Properties of Venom Peptides and Proteins in Solitary vs. Social Hunting Wasps

open access: yesToxins, 2016
The primary functions of venoms from solitary and social wasps are different. Whereas most solitary wasps sting their prey to paralyze and preserve it, without killing, as the provisions for their progeny, social wasps usually sting to defend their ...

Transcriptional factor regulation network and competitive endogenous RNA (ceRNA) network determining response of esophageal squamous cell carcinomas to neoadjuvant chemoradiotherapy [PDF]

open access: yesPeerJ, 2019
Background Neoadjuvant chemoradiotherapy (nCRT) followed by surgery benefits survival for patients with esophageal squamous cell carcinomas (ESCC) compared with surgery alone, but the clinical outcomes of nCRT are heterogeneous.

Evidence for systems-level molecular mechanisms of tumorigenesis [PDF]

open access: yes, 2007
Background: Cancer arises from the consecutive acquisition of genetic alterations. Increasing evidence suggests that as a consequence of these alterations, molecular interactions are reprogrammed in the context of highly connected and regulated cellular ...

The Genetic Basis of Color Polymorphism in the Orb‐Web Spider Gasteracantha cancriformis

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study investigates the genetic basis of coloration in the polymorphic spider Gasteracantha cancriformis using RNA‐seq data from different female color morphs. We assembled a reference transcriptome and identified differentially expressed genes associated with known pigmentation pathways, including carotenoids, melanin, ommochromes, and pteridines.

Natural and laboratory mutations in kuzbanian are associated with zinc stress phenotypes in Drosophila melanogaster [PDF]

open access: yes, 2017
Organisms must cope with altered environmental conditions such as high concentrations of heavy metals. Stress response to heavy metals is mediated by the metal-responsive transcription factor 1 (MTF-1), which is conserved from Drosophila to humans. MTF-1

A liver metalloendopeptidase which degrades the circulating hypotensive peptide hormones bradykinin and atrial natriuretic peptide

open access: yesBrazilian Journal of Medical and Biological Research, 1999
A new metalloendopeptidase was purified to apparent homogeneity from a homogenate of normal human liver using successive steps of chromatography on DEAE-cellulose, hydroxyapatite and Sephacryl S-200.

Validation of Messenger Ribonucleic Acid Markers Differentiating Among Human Acute Respiratory Distress Syndrome Subgroups in an Ovine Model of Acute Respiratory Distress Syndrome Phenotypes

open access: yesFrontiers in Medicine, 2022
BackgroundThe discovery of biological subphenotypes in acute respiratory distress syndrome (ARDS) might offer a new approach to ARDS in general and possibly targeted treatment, but little is known about the underlying biology yet.
