Inhibitory effect of oestradiol on the cardiac KV7.1/KCNE1 channel is species dependent

Experimental Physiology, Volume 111, Issue 1, Page 54-68, 1 January 2026.
Abstract Oestradiol (17β‐E2) is reported to prolong the cardiac action potential duration and QT interval, in part by affecting cardiac ion channels. Previous studies found inhibiting 17β‐E2 effects on the repolarizating cardiac KV7.1/KCNE1 channel, or its native current, in heterologous expression systems or tissue from animal species.

Insufficient or Excessive Niacin Intake Induced Glucose and Lipid Metabolic Disorders and Impaired Liver Health in Nile Tilapia

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Niacin (vitamin B3) is involved in the metabolic regulation of energy metabolism in animals. However, both deficiency and excess supplementation of niacin can induce profound physiological disturbances in fish. The present study investigated the effect of niacin on energy metabolism and liver health in Nile tilapia (Oreochromis niloticus).

Facilitation of I Kr current by some hERG channel blockers suppresses early afterdepolarizations. [PDF]

, 2019
Drug-induced block of the cardiac rapid delayed rectifying potassium current (I Kr), carried by the human ether-a-go-go-related gene (hERG) channel, is the most common cause of acquired long QT syndrome.

Arrhythmogenic Mechanisms of Novel Biomarkers in Cardiac Electrophysiology

Cardiology Research and Practice, Volume 2026, Issue 1, 2026.
Arrhythmia is an important cause of cardiovascular disease deaths and a serious threat to human health, but the current means of identification are limited. Biomarkers, with the advantages of easy access and rapid detection, have shown significant value in arrhythmia risk prediction, precision diagnosis, and prognosis assessment.

Molecular and clinical determinants of drug-induced long QT syndrome: an iatrogenic channelopathy. [PDF]

, 2004
More than 70 drugs present on the Swiss market can cause drug-induced long QT syndrome (LQTS), which is associated with torsades de pointes (TdP) arrhythmias, potentially leading to sudden cardiac death. Basic and clinical investigations performed during

Personalizing therapies over the course of hormone receptor‐positive/HER2‐negative metastatic breast cancer

CA: A Cancer Journal for Clinicians, Volume 76, Issue 1, January/February 2026.
ABSTRACT The hormone receptor (HR)‐positive/human epidermal growth factor receptor 2 (HER2)‐negative breast cancer subtype accounts for most early and metastatic breast cancer (MBC) cases. HR‐positive/HER2‐negative MBC is characterized by a relatively prolonged, although variable, disease course and substantial intertumoral and intratumoral ...

Early LQT2 Nonsense Mutation Generates N-Terminally Truncated hERG Channels with Altered Gating Properties by the Reinitiation of Translation

, 2012
Mutations in the human ether-a-go-go-related gene (hERG) result in long QT syndrome type 2 (LQT2). The hERG gene encodes a K+ channel that contributes to the repolarization of the cardiac action potential.
