Hydrogen sulfide protects H9c2 cardiac cells against doxorubicin-induced cytotoxicity through the PI3K/Akt/FoxO3a pathway.

Doxorubicin (DOX) is an efficient drug used in cancer therapy that also produces reactive oxygen species (ROS) that induces severe cytotoxicity, which limits its clinical application. Hydrogen sulfide (H2S), a novel gasotransmitter, has been shown to exert cardioprotective effects. The present study aimed to determine whether exogenous H2S protects H9c2 cardiac cells against DOX-induced cytotoxicity and whether these protective effects are mediated through the PI3K/Akt/FoxO3a pathway.

Resveratrol induces apoptosis through modulation of the Akt/FoxO3a/Bim pathway in HepG2 cells.

Resveratrol is a polyphenolic compound found in wine, which is mainly produced by the grapevine and exerts chemopreventive effects against hepatocellular carcinoma. However, the underlying molecular mechanisms have remained to be fully elucidated. The present study assessed whether resveratrol-induced apoptosis was mediated via the activation of the forkhead box O3a (FoxO3a) transcription factor.

Resveratrol protects cardiomyocytes from doxorubicin-induced apoptosis through the AMPK/P53 pathway.

Doxorubicin (DOX) is an efficient drug used in cancer therapy; however, it has severe cardiotoxic side effects. The aim of the present study was to investigate the effects of resveratrol on the adenosine monophosphate-activated protein kinase (AMPK)/P53 pathway in mediating DOX-induced cytotoxicity. H9c2 cells were exposed to 5 µM DOX for 24 h to establish a model of DOX-induced cardiotoxicity.

Upregulation of peroxiredoxin III in doxorubicin-induced cytotoxicity and the FoxO3a-dependent expression in H9c2 cardiac cells.

Doxorubicin (DOX) is an efficient drug used in cancer therapy; however, it produces reactive oxygen species (ROS) that induce severe cytotoxicity, limiting its clinical application. The aim of the present study was to investigate the role of peroxiredoxin III (Prx III) in DOX-induced H9c2 cell injuries. Following DOX treatment, the expression of phosphorylated-FoxO3a (p-FoxO3a) was decreased and Prx III expression was increased in H9c2 cells.

Hydrogen sulfide attenuates doxorubicin-induced cardiotoxicity by inhibiting the expression of peroxiredoxin III in H9c2 cells.

Doxorubicin (DOX) is a widely used chemotherapeutic agent, which can give rise to severe cardiotoxicity, limiting its clinical use. Preliminary evidence suggests that hydrogen sulfide (H2S) may exert protective effects on DOX‑induced cardiotoxicity. Therefore, the aim of the present study was to investigate whether peroxiredoxin III is involved in the cardioprotection of H2S against DOX‑induced cardiotoxicity.

Hydrogen sulfide attenuates doxorubicin-induced cardiotoxicity by inhibiting reactive oxygen species-activated extracellular signal-regulated kinase 1/2 in H9c2 cardiac myocytes.

Doxorubicin (DOX) is a potent and available antitumor therapeutic agent; however, its clinical application is limited due to its cardiotoxicity. Preliminary evidence suggests that hydrogen sulfide (H2S) may exert protective effects on DOX‑induced cardiotoxicity. Therefore, the aim of the present study was to investigate whether the extracellular signal‑regulated kinase (ERK) 1/2 signaling pathway is involved in the cardioprotection of H2S against DOX‑induced cardiotoxicity.

Hydrogen sulfide attenuates doxorubicin‑induced cardiotoxicity by inhibiting calreticulin expression in H9c2 cells.

Doxorubicin (DOX) is a potent and currently available antitumor therapeutic agent; however, its clinical application is limited by the occurrence of cardiotoxicity. Preliminary evidence indicates that hydrogen sulfide (H2S) may exert protective effects against DOX cardiotoxicity. Therefore, the aim of the present study was to investigate whether calreticulin (CRT) is involved in the cardioprotection of H2S against DOX‑induced cardiotoxicity.

Resveratrol protects PC12 cells from high glucose-induced neurotoxicity via PI3K/Akt/FoxO3a pathway.

Diabetes is known to be associated with neurodegenerative diseases. Resveratrol, a plant-derived polyphenolic compound found in red wine, possesses antioxidant properties. In this study, we aimed to investigate the effects of resveratrol on the phosphatidylinositol-3-kinase/protein kinase B (PI3K/Akt)/FoxO3a pathway in mediating high glucose (HG)-induced injuries in neuronal PC12 cells.
