Combination of nicotinamide mononucleotide and troxerutin induces full protection against doxorubicin-induced cardiotoxicity by modulating mitochondrial biogenesis and inflammatory response.
    Molecular biology reports, 2022, Volume: 49, Issue:9

    Clinical application of doxorubicin (DOX) is restricted due to its cardiotoxicity, reinforcing the significance of exploring new strategies to counteract DOX-induced cardiotoxicity. The present work aimed to investigate the ameliorative impact of combination therapy with nicotinamide mononucleotide (NMN) and troxerutin (TXR) on DOX-induced cardiotoxicity, with mitochondrial function/biogenesis and inflammatory response approach.. Male Wistar rats (n = 30, 250-300 g) were divided into groups with/without DOX and/or NMN and TXR, alone or in combination. Rats underwent 6 consecutive intraperitoneal injections of DOX (cumulative dose: 12 mg/kg). NMN (100 mg/kg/day; intraperitoneally) and/or TXR (150 mg/kg/day; orally) were administered for 28 days before DOX challenge. Seven days following the last injection of DOX, evaluation of cardiac histopathological changes, BNP and LDH levels, mitochondrial function (membrane potential, ROS generation, and ATP levels), expression of proteins involved in mitochondrial biogenesis (PGC-1α, NRF1, and TFAM), and inflammatory cytokines (TNF-α, IL-1β, and IL-6) was performed.. Combination of NMN and TXR significantly decreased the severity of histopathological damages, and BNP and LDH levels (P < 0.01 to P < 0.001). It also restored mitochondrial functional endpoints, and expression of proteins involved in mitochondrial biogenesis (P < 0.05 to P < 0.001), and decreased inflammatory cytokines (P < 0.01 to P < 0.001). The positive impacts of this combination therapy were more potent as compared to monotherapies.. These findings shed new light on the understanding of additive properties of NMN/TXR combination therapy in protecting against DOX-induced cardiotoxicity. The cardioprotective effect of this combination therapy may be mediated in part through the restoration of mitochondrial function/biogenesis associated with the PGC-1α/NRF1/TFAM pathway, and suppression of inflammatory response.

Effect of troxerutin on oxidative stress and expression of genes regulating mitochondrial biogenesis in doxorubicin-induced myocardial injury in rats.
    Naunyn-Schmiedeberg's archives of pharmacology, 2020, Volume: 393, Issue:7

    Because of limitation of doxorubicin (DOX) clinical application in chemotherapy due to its cardiotoxicity, finding new strategies to reduce DOX challenge and improve patients' outcomes is crucial. Due to positive cardiovascular impacts of troxerutin (TXR), here we have investigated the effect of TXR on DOX-induced cardiotoxicity by evaluating the myocardial oxidative stress and expression of genes regulating mitochondrial biogenesis. Male Wistar rats (250-300 g) were randomly allocated into four groups: control, TXR, DOX, and TXR + DOX. Troxerutin (150 mg/kg) was orally administrated once a day through a gavage tube for 4 weeks before DOX challenge. The TXR-treated and time-matched control rats received intraperitoneal injection of DOX (20 mg/kg). Three days after DOX challenge, the left ventricular samples were obtained to determine the expression of genes regulating mitochondrial biogenesis via real-time PCR. Myocardial creatine kinase (CK-mB), oxidative stress markers, and mitochondrial function (generation of reactive oxygen species or ROS and ATP levels) were also evaluated using commercial kits and spectrophotometric and fluorometric methods. DOX administration significantly increased the levels of CK-mB, malondialdehyde (MDA), and mitochondrial ROS levels, while reduced the cellular ATP production and expression levels of SIRT-1, PGC-1α, and NRF-2 as well as superoxide dismutase, glutathione peroxidase, and catalase activity in comparison to control group (P < 0.05 to P < 0.01). Pretreatment of DOX-received rats with TXR significantly upregulated the expression of all biogenesis genes and antioxidant enzymes with non-significant effect on catalase activity, and significantly reduced CK-mB and MDA levels toward control values (P < 0.05 to P < 0.01). Mitochondrial ROS and ATP levels were also restored significantly by pretreatment with TXR (P < 0.05). The data suggested that preconditioning of rats with TXR had protective effect on DOX-induced cardiotoxicity through inducing antioxidative properties and restoring the mitochondrial function and the expression profiles of myocardial SIRT-1/PGC-1α/NRF-2 network.
