Bisphenol F disrupts lipophagy and lysosomal acidification via ATGL-SIRT1-PPARα signaling in NAFLD-like hepatic changes

Ecotoxicology and Environmental Safety
Bisphenol F (BPF), a widely used substitute for bisphenol A (BPA), has raised growing concerns due to its potential metabolic toxicity. Recent studies suggest that BPF exposure is associated with lipid accumulation and non-alcoholic fatty liver disease ...

Structural Basis for Nucleobase Activation by the Adenine DNA Glycosylase MutY

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
DNA glycosylase MutY engages its adenine nucleobase substrate in a syn orientation with a catalytic Glu. X‐ray crystal structures of MutY with Glu replaced suggest that a disengaged “on hold” state with anti nucleobase orientation may explain how MutY avoids catastrophic activity at inappropriate adenines.

Mutation type‐specific transcriptomic signatures and readthrough therapy rescue in SMC1A‐related developmental and epileptic encephalopathy

Epilepsia, Volume 67, Issue 6, Page 3185-3198, June 2026.
Abstract Objective This study was undertaken to investigate the molecular consequences of pathogenic variants in the SMC1A gene—particularly those associated with developmental and epileptic encephalopathy (DEE85)—and to evaluate the therapeutic potential of ataluren in restoring SMC1A function and mitigating disease‐related transcriptomic and genomic ...

Regulation of reactivated contraction in teleost retinal cone models by calcium and cyclic adenosine monophosphate. [PDF]

, 1984
We have been using lysed cell models of teleost retinal cones to examine the mechanism of contraction in nonmuscle cells. We have previously reported that dark-adapted retinas can be lysed with the detergent Brij-58 to obtain cone motile models that ...

Adenosine Triphosphatase Activities of Muscle Sarcolemma

Journal of Biological Chemistry, 1973
Abstract Isolated sarcolemma hydrolyzed ATP in the presence of Mg2+ and Ca2+. MgATPase was stimulated by low concentrations of Ca2+ and inhibited by high concentrations of this cation. Membranes hydrolyzed p-nitrophenylphosphate in the presence of Mg2+; this activity was stimulated by Ca2+ and K+.

KCNJ4 variants disrupt inward‐rectifier potassium channel function and cause refractory epilepsy

Epilepsia, Volume 67, Issue 6, Page 3199-3210, June 2026.
Abstract Objective Epilepsy is a common neurological disorder with a strong genetic basis, most frequently arising from ion channel dysfunction. Although multiple inwardly rectifying potassium (Kir) channels have been implicated in epileptogenesis, the contribution of KCNJ4, which encodes the Kir2.3 channel, has not previously been established in human

A biochemical study on the level of lipids and glycoproteins in the serum and platelets of liver cirrhotic bleeders [PDF]

, 2006
Bleeding complication and abnormal platelet functions are associated with liver cirrhosis. The aim of the present investigation was to assess the functional integrity of platelets in terms of lipids like cholesterol and phospholipids, glycoproteins and ...

Structure and conformational plasticity of the intact Thermus thermophilus V/A-type ATPase [PDF]

, 2019
V (vacuolar)/A (archaeal)-type adenosine triphosphatases (ATPases), found in archaeaand eubacteria, couple ATP hydrolysis or synthesis to proton translocation across theplasma membrane using the rotary-catalysis mechanism. They belong to the V-typeATPase

Women with epilepsy: Evidence‐based counseling across the lifespan

Epilepsia, Volume 67, Issue 6, Page 2689-2706, June 2026.
Abstract Women with epilepsy (WWE) encounter distinct and evolving challenges across the lifespan that require clinical management extending beyond seizure control alone. Although awareness of sex‐specific aspects of epilepsy has increased, important gaps remain in their integration into routine care.

Differential regulation of mTORC1 by leucine and glutamine [PDF]

, 2015
The mechanistic target of rapamycin (mTOR) complex 1 (mTORC1) integrates environmental and intracellular signals to regulate cell growth. Amino acids stimulate mTORC1 activation at the lysosome in a manner thought to be dependent on the Rag small ...
