A Nonketotic Hyperglycinemia Mouse Shows Wide‐Ranging Biochemical Consequences of Elevated Glycine, Reduced Folate One‐Carbon Charging, and Serine Deficiency

Journal of Inherited Metabolic Disease, Volume 49, Issue 1, January 2026.
ABSTRACT Nonketotic hyperglycinemia is a severe neonatal epileptic encephalopathy caused by deficient glycine cleavage enzyme activity, for which currently no effective treatment exists. Incomplete understanding of brain biochemistry represents a major knowledge gap to develop new treatments.

Connecting the Dots: Bridging Microsamples and Conventional Blood Matrices in Metabolic Biomarker Analysis

Analytical Science Advances, Volume 6, Issue 2, December 2025.
ABSTRACT Bridging the gap between microsampling techniques and standard blood matrices presents a groundbreaking opportunity in metabolic biomarker analysis, offering minimally invasive, patient‐centric alternatives to traditional venipuncture. This review presents the current knowledge obtained from the comparison of biomarkers analysis in liquid ...

Uncovering Hyperhomocysteinemia: Global Risk Patterns and Molecular Disruption in Brain and Vascular Health

Journal of Neurochemistry, Volume 169, Issue 12, December 2025.
Elevated homocysteine results from genetic variants, impaired one‐carbon metabolism, nutritional deficiencies, and metabolic disorders. Hyperhomocysteinemia drives oxidative stress, inflammation, excitotoxicity, and epigenetic disruption, affecting multiple organs and systems.

Trial Readiness: Understanding the Natural History of Rare Diseases

Journal of Inherited Metabolic Disease, Volume 48, Issue 6, November 2025.
ABSTRACT Inherited metabolic diseases (IMD) represent the largest and still growing group of treatable genetic disorders and are increasingly amenable to targeted interventions that achieve varying degrees of prognostic improvement. Innovative therapies are on the horizon and offer promising opportunities for disease‐changing treatment for a variety of

Betaine Mitigates Paclitaxel‐Induced Hepatotoxicity in Rats by Regulating Oxidative Stress, Inflammation, Apoptosis, and Autophagy

Food Science &Nutrition, Volume 13, Issue 10, October 2025.
This study investigated the protective effect of betaine (BTN) against paclitaxel (PTL)‐induced liver injury in rats. The results showed that betaine reduced PTL‐induced liver injury by improving antioxidant levels, reducing inflammation, apoptosis, and regulating autophagy.

Effectiveness of Pyridoxal‐5′‐Phosphate in PNPO Deficiency: A Systematic Review

Journal of Inherited Metabolic Disease, Volume 48, Issue 5, September 2025.
ABSTRACT Pyridox(am)ine 5′‐phosphate oxidase (PNPO) deficiency is an ultrarare inherited neurometabolic disease, characterized by primarily neonatal‐onset B6‐responsive epileptic encephalopathies. Treatment often requires sustainable access to high‐quality pyridoxal‐5′‐phosphate (PLP, i.e., active vitamin B6), although some patients (also) respond to ...

Neurocognitive Impairment in Inherited Metabolic Disorders due to Intoxication and Energy Defects: A Systematic Review

Journal of Inherited Metabolic Disease, Volume 48, Issue 5, September 2025.
ABSTRACT Inherited metabolic disorders (IMD) can disrupt brain development and functioning, leading to cognitive and behavioral abnormalities. This systematic review aims to provide a comprehensive synthesis of the evidence regarding neurocognitive impairments in intoxication IMD due to the accumulation of small molecule disorders and energy‐related ...
