Instructions: Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: The molecular identity of calcium-activated chloride channels (CaCCs) in vascular endothelial cells remains unknown. This study sought to identify whether anoctamin-1 (Ano1, also known as TMEM16A) functions as a CaCC and whether hypoxia alters the biophysical properties of Ano1 in mouse cardiac vascular endothelial cells (CVECs).', 'Western blot, quantitative real-time PCR, confocal imaging analysis and patch-clamp analysis combined with pharmacological approaches were used to determine whether Ano1 was expressed and functioned as CaCC in CVECs.', 'Ano1 was expressed in CVECs. The biophysical properties of the current generated in the CVECs, including the Ca(2+) and voltage dependence, outward rectification, anion selectivity and the pharmacological profile, are similar to those described for CaCCs. The density of ICl ( C a) detected in CVECs was significantly inhibited by T16Ainh -A01, an Ano1 inhibitor, and a pore-targeting, specific anti-Ano1 antibody, and was markedly decreased in Ano1 gene knockdown CVECs. The density of ICl ( C a) was significantly potentiated in CVECs exposed to hypoxia, and this hypoxia-induced increase in the density of ICl ( C a) was inhibited by T16Ainh -A01 or anti-Ano1 antibody. Hypoxia also increased the current density of ICl ( C a) in Ano1 gene knockdown CVECs.
Output:
Does hypoxia augment the calcium-activated chloride current carried by anoctamin-1 in cardiac vascular endothelial cells of neonatal mice?
