Mitochondria spatially and temporally modulate VSMC phenotypes via interacting with cytoskeleton in cardiovascular diseases.

Cardiovascular diseases caused by atherosclerosis (AS) seriously endanger human health, which is closely related to vascular smooth muscle cell (VSMC) phenotypes. VSMC phenotypic transformation is marked by the alteration of phenotypic marker expression and cellular behaviour. Intriguingly, the mitochondrial metabolism and dynamics altered during VSMC phenotypic transformation.

Pin1/YAP pathway mediates matrix stiffness-induced epithelial-mesenchymal transition driving cervical cancer metastasis via a non-Hippo mechanism.

Cervical cancer metastasis is an important cause of death in cervical cancer. Previous studies have shown that epithelial-mesenchymal transition (EMT) of tumors promotes its invasive and metastatic capacity. Alterations in the extracellular matrix (ECM) and mechanical signaling are closely associated with cancer cell metastasis.

Investigation of the mechanism of reverse redistribution in thallium-201 myocardial perfusion scintigraphy in patients with suspicion for coronary artery spasm.

Background: Reverse redistribution (RR) is one of the features on myocardial perfusion scintigraphy (MPS) in patients with coronary artery spasm (CAS). This study was aimed to explore the mechanism of RR in patients with suspicion for CAS.

Methods And Results: Thirty patients with RR and suspicion for CAS but without coronary artery stenosis (RR group) and 32 control patients without RR (control group) underwent coronary angiography before and after a dipyridamole administration.

Characteristics of stress tests and symptoms in patients with myocardial bridge and coronary artery spasm.

Background: A relationship between coronary artery spasm (CAS) and myocardial bridge (MB) has been noticed. This study was designed to investigate the differences of stress tests and symptoms between CAS patients with or without MB.

Methods: Two hundred and sixteen patients with atypical chest pain who underwent coronary angiography and acetylcholine provocation test were divided into MB group (n=68) and nonmyocardial bridge group (NMB, n=148).
