How does acetic acid affect endothelial cell function?5 answersAcetic acid, specifically flavone acetic acid (FAA), has been shown to affect endothelial cell function. FAA inhibits endothelial cell proliferation and compromises tubule formation, which are important processes in angiogenesis. Additionally, FAA reduces vascular development in the chick embryo chorioallantoic membrane, further indicating its impact on endothelial cell function. Acetylsalicylic acid, another form of acetic acid, has been found to have a marked inhibitory effect on metalloproteinase-2 secretion and expression in endothelial cells cultured in high glucose conditions. This suggests that acetylsalicylic acid could potentially prevent the angiogenic process associated with diabetes complications. Overall, acetic acid, in the form of FAA or acetylsalicylic acid, has been shown to have effects on endothelial cell function, including inhibition of proliferation, compromised tubule formation, and reduced metalloproteinase-2 secretion and expression.
Which channels and transporter are involved in cell swelling?5 answersCell swelling is regulated by various channels and transporters. The Na+-K+-Cl- cotransporters (NKCC) have been shown to play a role in cell volume regulation and are involved in astrocyte swelling/brain edema in neurological disorders. Additionally, ClC3 channels/transporters have been found to be upregulated in idiopathic pulmonary arterial hypertension (IPAH) and contribute to excessive proliferation of pulmonary arterial smooth muscle cells (PASMCs). The nonselective cation channel (NSCC) has also been implicated in cell swelling and necrosis, as it becomes activated under severe oxidative stress and leads to Na+ influx. Furthermore, volume-activated taurine efflux pathways, such as volume-sensitive anion channels and the band 3 anion-exchanger, have been proposed to be involved in osmosensitive taurine transport. These channels and transporters play crucial roles in cell swelling and are potential targets for therapeutic interventions in various pathological conditions.
