OBJECTIVE Previous studies have confirmed Slug as a key player in regulating phenotypic changes in several cell models, however, its role in smooth muscle cells (SMC) has never been assessed. The purpose of this study was to evaluate the expression of Slug during the phenotypic switch of SMC in vitro and throughout the development of vascular remodeling. METHODS AND RESULTS Slug expression wa...
The study of two-phase fluid flow behavior in hydraulic structures such as pressurized flow tunnels, culverts, sewer pipes, junctions and other similar conduits is of great importance. A two-phase mixture flowing in a pipe can exhibit several interfacial geometries such as bubbles, slugs or films, depending on the fluid and hydrodynamic properties of flow. The main variables, giving rise to a v...
An epithelial-mesenchymal cell transformation occurs during the development of the endocardial cushions in the atrioventricular (AV) canal of the heart. We hypothesized that the transcription factor Slug is required for this epithelial-mesenchymal cell transformation since Slug is required for similar transformations during gastrulation and neural crest differentiation in chicken embryos. We fo...
Here, a unified 3D numerical model of gas-liquid two-phase flow in horizontal pipe was established using the interface capture method based on open source software package OpenFOAM. Through simulation natural slugging and development process slug under different working conditions, motion, phase structure, pressure velocity field distributions liquid were fully developed analyzed. The results a...
Many volcanoes around the world are persistently active with continuous degassing for years or even centuries, sometimes exceeding historic records. Such long-term stability contrasts short-term instability, reflected in eruptive episodes that punctuate passive degassing. These two aspects of persistent activity, as opposed to often conceptualized through distinct model frameworks: Exchange-flo...
One of highly pathogenic breast cancer cell types are the triple negative (negative in the expression of estrogen, progesterone, and ERBB2 receptors) breast cancer cells. These cells are highly motile and metastatic and are characterized by high levels of the metastasis regulator protein SLUG. Using isogenic breast cancer cell systems we have shown here that high motility of these cells is dire...
