Alternative Pathway for Methyl Supply through the Coupling of SHMT1 and PEMT to Maintain Astrocytic Homeostasis in Parkinson's Disease

Advanced Science, Volume 13, Issue 7, 3 February 2026.
In Parkinson's disease, SHMT1 downregulation disrupts its interaction with PEMT in astrocytes, reducing SAM levels. This leads to H3K4me1 hypomethylation and decreased Slc1a2/Glul expression, ultimately exacerbating neuroexcitotoxicity and dopaminergic neuron loss.

Spermidine Reproduces the Anti‐Inflammatory Effects of Intermittent Fasting and Prevents Urate and Calcium Pyrophosphate Crystal‐Induced Inflammation

Arthritis &Rheumatology, Volume 78, Issue 2, Page 449-462, February 2026.
Objective Gout caused by the formation of monosodium urate (MSU) crystals and calcium pyrophosphate (CPP) deposition disease are two major types of microcrystalline pathologies in adults. They are responsible for recurrent flares that rely on interleukin (IL) 1β via activation of the NLRP3 inflammasome.

A dodecylamine derivative of cyanocobalamin potently inhibits the activities of cobalamin-dependent methylmalonyl-CoA mutase and methionine synthase of Caenorhabditis elegans

FEBS Open Bio, 2014
In this study, we showed that cyanocobalamin dodecylamine, a ribose 5′-carbamate derivative of cyanocobalamin, was absorbed and accumulated to significant levels by Caenorhabditis elegans and was not further metabolized.

Consequences of the divergence of Methionine AdenosylTransferase [PDF]

, 2020
AbstractMethionine adenosyltransferase (MAT), which catalyzes the biosynthesis of S-adenosylmethionine from L-methionine and ATP, is an ancient, highly conserved enzyme present in all three domains of life. Although the MAT enzymes of each domain are believed to share a common ancestor, the sequences of archaeal MATs show a high degree of divergence ...

Lactylated SPTAN1 Accelerates Hepatocellular Carcinoma Progression by Promoting NOTCH1/HES1 Activation and Immunosuppression

Advanced Science, Volume 13, Issue 6, 30 January 2026.
This study identifies SPTAN1‐kla as a novel oncogenic driver in HBV‐driven HCC, linking metabolic, epigenetic, and immune mechanisms. SPTAN1‐kla promotes HCC progression via NOTCH1/HES1 activation and immunosuppression. Findings highlight that targeting SPTAN1‐kla provides a framework for HCC treatment to improve clinical outcomes in HBV infected ...

Sex-specific dysregulation of cysteine oxidation and the methionine and folate cycles in female cystathionine gamma-lyase null mice: a serendipitous model of the methylfolate trap

Biology Open, 2015
In addition to its role in the endogenous synthesis of cysteine, cystathionine gamma-lyase (CGL) is a major physiological source of the vasorelaxant hydrogen sulfide.

Activation of USP30 Disrupts Endothelial Cell Function and Aggravates Acute Lung Injury Through Regulating the S‐Adenosylmethionine Cycle

Advanced Science, Volume 13, Issue 2, 9 January 2026.
USP30 deubiquitinates and stabilizes MAT2A, thereby regulating DNA methylation and miRNA expression, which ultimately leads to disruption of lung endothelial barrier and inflammation. Abstract Microvascular dysfunction is a key contributor to the development of acute inflammatory diseases, characterized by heightened vascular hyperpermeability and ...

A Modular Chemoenzymatic Cascade Simplifies Divergent Synthesis of Natural and Unnatural Benzylisoquinoline Alkaloids

Advanced Science, Volume 13, Issue 1, 5 January 2026.
A simplified chemoenzymatic platform is designed to integrate an enzyme cascade with subsequent chemical steps, enabling the divergent production of diverse benzylisoquinoline alkaloids (BIAs). Demonstrating remarkable versatility and enantioselectivity, four distinct classes of BIAs are efficiently generated, in which the natural medicine papaverine ...

Methionine Adenosyltransferase Purified from Rat Liver

Croatica Chemica Acta, 2002
Methionine adenosyltransferase (MAT III), also known as S-adeno-sylmethionine synthetase, was purified from rat liver and crystallized. X-ray diffraction data were collected using a microfocused synchrotron radiation. The crystallization conditions were extensively optimized but final crystal size was never larger than 303 pm3.
