Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

The FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

The Effect of Vitamin D3 Supplementation on the Risk of Falls in a General Population—The Finnish Vitamin D Trial

Journal of the American Geriatrics Society, EarlyView.
ABSTRACT Background The impact of vitamin D on fall incidence remains controversial. We studied the effect of 5 years of vitamin D3 supplementation on the risk of falls in a double‐blind, placebo‐controlled randomized trial with generally healthy, community‐dwelling men and women in Finland.

Cardiac remodelling in type 2 diabetes: Pathophysiological mechanisms and opportunities for multiscale computational modelling and simulation

The Journal of Physiology, EarlyView.
Abstract figure legend Overview of multiscale cardiac remodelling in type 2 diabetes and how to model and simulate these changes using a human‐based, multiscale computational framework. Cardiac remodelling in type 2 diabetes occurs at ionic channel, protein, cellular, tissue and whole‐organ level, affecting the electrophysiological function, mechanical

Stac2 genetic deletion alters mouse chromaffin cells’ CaV channel composition, increases membrane excitability and reduces vesicle exocytosis

The Journal of Physiology, EarlyView.
Abstract figure legend Stac2 adaptor protein is expressed in neurons and endocrine cells. Using a global Stac2 knockout mouse model here we investigated the role of endogenous Stac2 in adrenal gland mouse chromaffin cell (MCC) excitability and catecholamine vesicle exocytosis.

When NCX switches sides: Experimental and computational insights into Ca2+ regulation in the heart

The Journal of Physiology, EarlyView.
Abstract figure legend Due to its presence inside the dyadic cleft, Na+/Ca2+ exchanger (NCX) builds a functional unit together with L‐type calcium channels and ryanodine receptors in the dyadic cleft. NCX acts bidirectionally (forward and reverse mode) dependent on extracellular calcium ([Ca2+]o) and sodium ([Na+]o) concentrations and the membrane ...

Rationale and Trial Design of DAWNA‐FES Trial: Single‐Arm Phase II Study of Endocrine Therapy With Dalpiciclib After Progression on CDK4/6 Inhibition Based on [18F]FES PET/CT in Patients With HR+/HER2− Advanced Breast Cancer

Cancer Innovation, Volume 5, Issue 3, June 2026.
The DAWNA‐FES trial is a prospective, single‐center, single‐arm phase II study evaluating dalpiciclib plus endocrine therapy in patients with HR+/HER2− advanced breast cancer who have progressed on prior CDK4/6 inhibitors and have at least one [18F]FES‐positive lesion.

Oxidative Stress in the Tumor Immune Microenvironment: Mechanisms and Therapeutic Perspectives

MedComm – Oncology, Volume 5, Issue 2, June 2026.
Oxidative stress is involved in several key processes in cancer, including redox regulation, DNA damage, post‐translational modifications, transcriptional regulation, epigenetic modifications, metabolic reprogramming, cell death, and immune modulation. These mechanisms collectively influence tumor progression, immune evasion, and therapeutic responses,
