Downregulation of HDAC2 attenuates ventricular arrhythmias in a mouse model of cardiac hypertrophy through upregulation of KCHIP2 expression.

Aims: Decrease in repolarizing K+ currents, particularly the fast component of transient outward K+ current (Ito,f), prolongs action potential duration (APD) and predisposes the heart to ventricular arrhythmia during cardiac hypertrophy. Histone deacetylases (HDACs) have been suggested to participate in the development of cardiac hypertrophy, and class I HDAC inhibition has been found to attenuate pathological remodeling. This study investigated the potential therapeutic effects of HDAC2 on ventricular arrhythmia in pressure overload-induced cardiac hypertrophy.

A Laterally Excited Bulk Acoustic Wave Resonator Based on LiNbO with Arc-Shaped Electrodes.

High frequency and large bandwidth are growing trends in communication radio-frequency devices. The LiNbO thin film material is expected to become the preferred piezoelectric material for high coupling resonators in the 5G frequency band due to its ultra-high piezoelectric coefficient and low loss characteristics.

6 GHz lamb wave acoustic filters based on A1-mode lithium niobate thin film resonators with checker-shaped electrodes.

The first-order antisymmetric (A1) mode lamb wave resonator (LWR) based on Z-cut LiNbO thin films has attracted significant attention and is widely believed to be a candidate for next-generation reconfigurable filters with high frequency and large bandwidth (BW). However, it is challenging for traditional interdigitated electrodes (IDTs) based LWR filters to meet the requirement of a clean frequency spectrum response and enough out-of-band (OoB) rejection. To solve the problem, we propose LWRs with checker-shaped IDTs for the design of filters that meet the Wi-Fi 6E standard.

The Multifunctional Role of KCNE2: From Cardiac Arrhythmia to Multisystem Disorders.

The KCNE2 protein is encoded by the gene and is a member of the KCNE protein family, also known as the MinK-related protein 1 (MiRP1). It is mostly present in the epicardium of the heart and gastric mucosa, and it is also found in the thyroid, pancreatic islets, liver and lung, among other locations, to a lesser extent. It is involved in numerous physiological processes because of its ubiquitous expression and partnering promiscuity, including the modulation of voltage-dependent potassium and calcium channels involved in cardiac action potential repolarization, and regulation of secretory processes in multiple epithelia, such as gastric acid secretion, thyroid hormone synthesis, generation and secretion of cerebrospinal fluid.
