Special Issue Information

Dear Colleagues,

Cancer drugs are commonly used to treat tumors. Unfortunately, the majority of cancer drugs (doxorubicin, ponatinib, cisplatin, etc.) induce cardiomyopathy and muscle weakness as a side effect. The exact mechanisms of action of these drugs are far from clear; however, based on current research, it is suggested that increased oxidative stress, inflammation, mitochondrial dysfunction, and cell death are prominent mechanisms involved in the development as well as progression of these diseases. Recent data suggest that researchers are investigating various therapeutic approaches, such as miRNA technology, antioxidative as well as anti-inflammatory drugs, antiapoptotic therapeutic options, cell therapy, and exosomes.

Pharmaceuticals is organizing a Special Issue on the topic of cancer drug toxicity and interventions. In this Special Issue, we invite both original and review articles that cover the current concepts of anticancer-drug-induced toxicity in the heart and muscles. These articles can be of a wider scope, including topics such as oxidative stress, cell signaling, cell death, tissue remodeling, inflammation, and other relevant molecular mechanisms that are involved in anticancer-drug-induced cardiac as well as muscle toxicity. We will also welcome any current therapeutic strategies being investigated to attenuate anticancer-drug-induced side effects in tissues.

Doxorubicin (DOX) is an incessantly used chemotherapeutic drug that can cause detrimental dose-dependent effects such as cardiotoxicity and congestive heart failure. Hence, there is a need to discover innovative therapeutic approaches to counteract DOX-induced cardiotoxicity (DIC). MSC-Exos have shown to reduce apoptosis and cardiac fibrosis and promote cardiomyocyte proliferation in myocardial infracted mice. However, the effect of MSC-Exos on ameliorating DOX-induced pyroptosis has not been investigated. In this current study, H9c2 were first exposed to DOX to stimulate pyroptosis, followed by subsequent treatment with MSC-Exos, with further analysis performed through immunocytochemistry, western blotting, and RT-PCR. Our data depicted that post-treatment with MSC-Exos significantly (p < 0.05) reduced the HMGB1/TLR4 axis, inflammasome formation (NLRP3), pyroptotic markers (caspase-1, IL-1β, and IL-18), and the pyroptotic executioner (GSDMD) in DOX-treated H9c2 cells. In conclusion, our data show that MSC-Exos attenuates inflammation-induced pyroptosis in our in vitro DIC model. Our findings indicate that MSC-Exos may serve as a promising therapeutic intervention for mitigating DIC, as they maintain the therapeutic capabilities of MSCs while circumventing the drawbacks associated with traditional stem cell therapy.

Platelet-derived growth factors (PDGFs) and PDGF receptors (PDGFRs) play essential roles in promoting cholangiocarcinoma (CCA) cell survival by mediating paracrine crosstalk between tumor and cancer-associated fibroblasts (CAFs), indicating the potential of PDGFR as a target for CCA treatment. Clinical trials evaluating PDGFR inhibitors for CCA treatment have shown limited efficacy. Furthermore, little is known about the role of PDGF/PDGFR expression and the mechanism underlying PDGFR inhibitors in CCA related to Opisthorchis viverrini (OV). Therefore, we examined the effect of PDGFR inhibitors in OV-related CCA cells and investigated the molecular mechanism involved. We found that the PDGF and PDGFR mRNAs were overexpressed in CCA tissues compared to resection margins. Notably, PDGFR-α showed high expression in CCA cells, while PDGFR-β was predominantly expressed in CAFs. The selective inhibitor CP-673451 induced CCA cell death by suppressing the PI3K/Akt/Nrf2 pathway, leading to a decreased expression of Nrf2-targeted antioxidant genes. Consequently, this led to an increase in ROS levels and the promotion of CCA apoptosis. CP-673451 is a promising PDGFR-targeted drug for CCA and supports the further clinical investigation of CP-673451 for CCA treatment, particularly in the context of OV-related cases. Full article
