New components in genetic regulation of age‐dependent compound leaf architecture in pea
Compound leaf development in pea (Pisum sativum). Summary Pea (Pisum sativum L.) is a classic model for compound leaf development. Pea leaves typically consist of a proximal series of paired lateral leaflets substituted distally by filiform tendrils, and the number of lateral organ pairs increases with ontogeny.

Identification of Sodium/Myo‐Inositol Transporter 1 as a Major Determinant of Arterial Contractility
The tonicity‐responsive enhancer binding‐protein (TonEBP) and serum glucocorticoid kinase (SGK) sense a rise in extracellular hypertonicity resulting in an increase SMIT1 membrane abundance in vascular smooth muscle cells. SMIT1 associates with Kv7.4/5, Gβγ, and KCNE4, promoting hyperpolarization, reduced voltage‐gated calcium channel (VGCC) opening ...

Discovery of Ro 41‐0960, a Non‐Steroidal Inhibitor of the Na+/K+‐ATPase
Ro 41‐0960 is a non‐steroidal Na+/K+‐ATPase inhibitor with low micromolar potency and a mixed inhibitory mechanism distinct from classical cardiotonic steroids, without acute pro‐arrhythmic effects in human cardiomyocytes. The Na+/K+‐ATPase (NKA) is a central regulator of cardiac ion homeostasis and a validated target for heart failure.

Copper(II/III) Redox Couple Enables C─H Methylation via a Radical Mechanism Analogous to SAM Enzymes
Biological C–H methylation proceeds through radical pathways mediated by one‐electron redox cofactors, yet no synthetic model has reproduced this reactivity. Here, we report the first isolable Cu(II/III)–methyl complexes that mediate C–H methylation through hydrogen atom transfer and methyl radical rebound.

Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

BCL9 and BCL9L drive bladder cancer progression by enhancing β‐catenin signaling, promoting proliferation, migration, invasion, and organoid growth. Genetic depletion of BCL9(L) suppresses malignant phenotypes, while pharmacological disruption of the β‐catenin/BCL9(L) complex with ZW4864 inhibits canonical Wnt signaling and tumor‐associated cellular ...

An integrated probiotic system is engineered to execute a programmed therapeutic cascade against inflammatory bowel disease. Upon pathological signals, the system sequentially performs ROS scavenging, tungsten release, and selective pathogen suppression, thereby breaking the oxidative stress–dysbiosis cycle to remodel gut microbiota and reinforce ...

Biological function arises from aggregates rather than from molecules. Comparing biomimetic systems on a common basis reveals three transferable design rules governing hierarchical assembly, interfacial gradients, and stimulus‐coupled anisotropy, and identifies self‐healing and single‐step multiscale integration as properties that do not transfer to ...

Perinatal lead (Pb) exposure and alterations to amyloid beta and metabolic profiles in the brain
Abstract INTRODUCTION Developmental neurotoxicant exposures (e.g., lead [Pb]) are suspected contributors to dementia. Dementia is characterized by amyloid beta (Aβ) plaques and dysregulated metabolism. To better understand the relationship between environment and dementia risk, we assessed the impact of perinatal Pb exposure on dementia‐related ...
