Peroxiredoxin 4 Involved in Spermatogenesis by Affecting Oxidative Stress and Ferroptosis

Andrology, EarlyView.
ABSTRACT Background The main functions of testes are sperm production and androgen secretion in testicular befitting microenvironment. Excessive level of the reactive oxygen species (ROS) from metabolism and cellular events can lead to oxidative stress (OS) and ferroptosis, which injure the functions of mitochondria and endoplasmic reticulum (ER) of ...

The architecture of redox microdomains: Cascading gradients and peroxiredoxins’ redox-oligomeric coupling integrate redox signaling and antioxidant protection

Redox Biology
In the cytosol of human cells under low oxidative loads, hydrogen peroxide is confined to microdomains around its supply sites, due to its fast consumption by peroxiredoxins.

Non‐canonical PKG1 regulation in cardiovascular health and disease

British Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

Varicocele and testicular function

Asian Journal of Andrology, 2015
Testicular varicocele, a dilation of the veins of the pampiniform plexus thought to increase testicular temperature via venous congestion, is commonly associated with male infertility.

Long-Term Adverse Effects of Oxidative Stress on Rat Epididymis and Spermatozoa

Antioxidants, 2020
Oxidative stress is a common culprit of several conditions associated with male fertility. High levels of reactive oxygen species (ROS) promote impairment of sperm quality mainly by decreasing motility and increasing the levels of DNA oxidation ...

Long non‐coding RNAs at the crossroads of inflammation, cancer and angiogenesis: Molecular mechanisms and their potential as therapeutic targets

British Journal of Pharmacology, EarlyView.
Long non‐coding RNAs (lncRNAs), a broad class of non‐protein‐coding RNAs, are characterized as new regulators of gene expression at the epigenetic, transcriptional, and post‐transcriptional level. Thus, lncRNAs are involved in the regulation of physiological processes and the development of human diseases and cancer by modulating proinflammatory ...

Organ‐Specific Cancer‐Associated Fibroblast Subtypes Across the Digestive System Linked to Cancer Hallmarks

Cancer Science, EarlyView.
We integrated 14 single‐cell RNA‐seq datasets and 18 bulk cohorts to define eight CAF subtypes in GI cancers. myCAF1 and myCAF2 promoted immunosuppressive, poor‐prognosis niches, whereas iCAF1 was linked to favorable prognosis and antitumor immunity.

The redox switch that regulates molecular chaperones

Biomolecular Concepts, 2015
Modification of reactive cysteine residues plays an integral role in redox-regulated reactions. Oxidation of thiolate anions to sulphenic acid can result in disulphide bond formation, or overoxidation to sulphonic acid, representing reversible and ...

Shared dysregulation of complement and phosphorylation pathways in the cerebrospinal fluid of encephalitis, Aicardi–Goutières syndrome, and autism

Developmental Medicine &Child Neurology, EarlyView.
Abstract Aim To identify shared and disorder‐specific molecular alterations across encephalitis, Aicardi–Goutières syndrome (AGS), and autism spectrum disorder (ASD) using cerebrospinal fluid (CSF) proteomics. Method In this cross‐sectional case–control study, mass‐spectrometry‐based proteomics was performed on archived CSF samples collected between ...
