Reduced Mechanical Tactile Stimulation Under Space Microgravity Affects Synaptic Signaling and Contributes to Neuromuscular Aging in Caenorhabditis elegans

The FASEB Journal, Volume 40, Issue 12, 30 June 2026.
Microgravity (μG) reduces mechanical tactile stimulation in Caenorhabditis elegans, causing neuromuscular decline, altered gene expression, synaptic defects, and accelerated aging phenotypes. The gentle‐touch mechanoreceptor MEC‐4 mediates μG‐induced body length reduction and extracellular matrix gene downregulation.

The crystal structure of an extracellular catechol oxidase from the ascomycete fungus Aspergillus oryzae

, 2013
Catechol oxidases (EC 1.10.3.1) catalyse the oxidation of o-diphenols to their corresponding o-quinones. These oxidases contain two copper ions (CuA and CuB) within the so-called coupled type 3 copper site as found in tyrosinases (EC 1.14.18.1) and ...

Steric control of copper nuclearity in sulfur ligated oxidase mimics alters catechol and phenoxazinone oxidation

Scientific Reports
Control over copper nuclearity is a key issue in bioinspired oxidation chemistry, yet its mechanistic consequences in sulfur-donor environments remain insufficiently understood.

Two candidate gene polymorphisms in ADHD children: a case-control study of catechol-O-methyltransferase (COMT) and monoamine oxidase B (MAOB) genes

Archives of Medical Science, 2006
Introduction: Attention-deficit hyperactivity disorder (ADHD) is a common polygenic heritable disorder. We have investigated the relationship between ADHD and polymorphisms of catechol-O-methyltransferase (COMT) and monoaminooxidase B (MAOB) genes. It is
