Upregulation of p67 < sup > phox < /sup > in response to ischemia/reperfusion is cardioprotective by increasing ZIP2 expression via STAT3
In conclusion, an increase of p67phox expression in response to Zn2+ is an intrinsic adaptive response to I/R and leads to cardioprotection against I/R by upregulating ZIP2 via STAT3.PMID:35296207 | DOI:10.1080/10715762.2022.2052057

Hexavalent chromium induces centrosome amplification through ROS-ATF6-PLK4 pathway in colon cancer cells
In conclusion, our results suggest that hexavalent chromium induces CA via the ROS-ATF6-PLK4 pathway and provides molecular targets for inhibiting chromium-mediated CA, which may be useful for the assessment of CA in chromium-promoted tumorigenesis and cancer cell metastasis.

Molecules, Vol. 27, Pages 1346: Mitochondrial ROS-Mediated Metabolic and Cytotoxic Effects of Isoproterenol on Cardiomyocytes Are p53-Dependent and Reversed by Curcumin
g-Han Lee
Acute &beta;-adrenergic stimulation contributes to heart failure. Here, we investigated the role of p53 in isoproterenol (ISO)-mediated metabolic and oxidative stress effects on cardiomyocytes and explored the direct protective effects offered by the antioxidant nutraceutical curcumin. Differentiated H9C2 rat cardiomyocytes treated with ISO were assayed for glucose uptake, lactate release, and mitochondrial reactive oxygen species (ROS) generation. Survival was assessed by sulforhodamine B assays. Cardiomyocytes showed significantly decreased glucose uptake and lactate release, as well as increased ce...

Anti-inflammatory and anti-fibrotic effects of modafinil in nonalcoholic liver disease
Biomed Pharmacother. 2021 Dec;144:112372. doi: 10.1016/j.biopha.2021.112372. Epub 2021 Oct 28.ABSTRACTSmall- and intermediate-conductance Ca2+-activated K+ channels, KCa2.3 and KCa3.1, are involved in cellular signaling processes associated with inflammation and fibrosis. KCa2.3 and KCa3.1 are upregulated by proinflammatory cytokines and profibrotic growth factors. Cyclic AMP, which downregulates KCa2.3 and KCa3.1, is elevated by modafinil in cells; accordingly, we investigated whether modafinil exerts anti-inflammatory and anti-fibrotic responses via KCa2.3- and KCa3.1-mediated pathways in high-fat diet (HFD)- or thioacet...

Atractylodin inhibits fructose-induced human podocyte hypermotility via anti-oxidant to down-regulate TRPC6/p-CaMK4 signaling
Eur J Pharmacol. 2021 Nov 12:174616. doi: 10.1016/j.ejphar.2021.174616. Online ahead of print.ABSTRACTHigh fructose has been reported to drive glomerular podocyte oxidative stress and then induce podocyte foot process effacement in vivo, which could be partly regarded as podocyte hypermotility in vitro. Atractylodin possesses anti-oxidative effect. The aim of this study was to explore whether atractylodin prevented against fructose-induced podocyte hypermotility via anti-oxidative property. In fructose-exposed conditionally immortalized human podocytes, we found that atractylodin inhibited podocyte hypermotility, and up-re...

Cigarette Smoke Promotes Interleukin-8 Production in Alveolar Macrophages Through the Reactive Oxygen Species/Stromal Interaction Molecule 1/Ca2+ Axis
In conclusion, our study demonstrates that CSE-induced ROS production may increase the expression of STIM1 in macrophages, which further promotes the release of IL-8 by regulating Ca2+ entry. These data suggest that STIM1 may play a crucial role in CSE-induced ROS production and inflammation, and participate in the pathogenesis of COPD.
