Flavonols are a class of flavonoids. Unlike other classes of flavonoids, flavonols strongly accumulate in guard cells, but the role of their accumulation in guard cells is still unclear so far.The overexpression of TaFLS1, a flavonol synthase gene from wheat, improves flavonol content in guard cells of Arabidopsis, while the mutant fls1-3 of Arabidopsis AtFLS1 reduces the content. Both the increase of flavonols by TaFLS1 overexpression and the decrease in fls1-3 change stomatal apeture, showing the association between flavonols and stomatal movements.

View SamplesIt is well known that rennin-angiotensin-aldosterone system (RAAS) plays a critical role in the development of diabetic cardiomyopathy. The present study was aimed to clarify the role of a novel member of RAAS, angiotensin IV (Ang IV) and its downstream mediator forkhead box protein O1 (FoxO1), in the pathogenesis of diabetic cardiomyopathy. In vivo, diabetic mice were treated with low-, medium- and high-dose Ang IV, AT4R antagonist divalinal, FoxO1 inhibitor AS1842856 (AS), or their combinations. In vitro, cardiomyocytes and cardiofibroblasts were treated with different concentrations of glucose, low-, medium- and high-dose Ang IV, divalinal, FoxO1-overexpression plasmid (FoxO1-OE), AS or their combinations.

View SamplesActivation of the systemic and myocardial rennin-angiotensin-aldosterone system (RAAS) by hyperglycemia plays a critical role in the development of diabetic cardiomyopathy. To test the hypothesis that AngIV protects against diabetic cardiomyopathy via stimulation of AT4R and inhibition of overactive autophagy, diabetic mice were treated with low-, medium- and high-dose AngIV, AT4R antagonist divalinal, forkhead box protein O1 (FoxO1) inhibitor AS1842856 (AS) or their combinations. In vitro, cardiomyocytes were treated with different concentrations of glucose, low-, medium- and high-dose AngIV, divalinal, FoxO1-overexpression plasmid (FoxO1-OE), AS or their combinations.

View SamplesDespite much knowledge is well-known on the transcriptional and enzymological regulation of many genes in starch synthesis, including SBEb, Waxy, and SUS-SH1 genes, less information is available on their expression profiles as a consequence of their dysfunction. Hence, transcriptional adjustments in response to mutations were required for a better understanding of starch biosynthesis pathway, others metabolism and cell response.
