Oligopeptide foldamers are promising as minimalist functional analogues to proteins. Herein, we report a versatile and cost-effective experimental scheme in the gas phase that can facilely identify selective oligopeptides and unambiguously resolve the corresponding folding conformations. Based on this methodology, a stereoselective oligopeptide clamp targeting β-blockers is successfully identified.

NMDA receptors in the prefrontal cortex (PFC) play a crucial role in cognitive functions. Previous research has indicated that angiotensin II (Ang II) affects learning and memory. This study aimed to examine how Ang II impacts NMDA receptor activity in layer V pyramidal cells of the rat PFC.

Angiotensin II (Ang II) is an effective vasoconstriction peptide, a major effector molecule of the renin-angiotensin-aldosterone system (RAAS) and one of the important causes of endothelial dysfunction. Ferroptosis is considered to be involved in the occurrence and development of cardiovascular diseases. This study is dedicated to exploring the role and mechanism of Ang II-induced ferroptosis in HUVECs and to finding molecular targets for vascular endothelial injury and dysfunction during the progression of hypertension.

Aldehyde dehydrogenase 2 (ALDH2), a pivotal enzyme in the metabolism of toxic aldehydes produced by oxidative stress, has been demonstrated to play a cardioprotective role in cardiovascular diseases. Antrodia cinnamomea triterpenoids (ACT) is a medicinal mushroom with anti-inflammatory and antioxidant properties, and our previous study found that ACT can exert anti-fatty liver effects by regulating ALDH2. This study aimed to elucidate the impact of ACT and its monomer on cardiac hypertrophy and investigate the relationship between its pharmacological mechanism and ALDH2.

Background: Sustained pathological cardiac hypertrophy (CH) is an independent risk factor for increased incidence and mortality of cardiovascular events.
Objectives: This research was designed to unravel the role of long non-coding RNA (LncRNA) CCAT2 in CH progression.
Methods: Transverse aortic constriction (TAC) procedures were conducted to construct a pressure overload-induced in vivo CH model.

The pathological activation of cardiac fibroblasts (CFs) plays a crucial role in the development of pressure overload-induced cardiac remodelling and subsequent heart failure (HF). Growing evidence demonstrates that multiple microRNAs (miRNAs) are abnormally expressed in the pathophysiologic process of cardiovascular diseases, with miR-425 recently reported to be potentially involved in HF. In this study, we aimed to investigate the effects of fibroblast-derived miR-425-5p in pressure overload-induced HF and explore the underlying mechanisms.
