[PMID: 37919370 PMCID: PMC10622533 DOI: 10.1038/s41598-023-46216-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Accepted: 10/30/2023] [Indexed: 11/04/2023] Open
Abstract
Doxorubicin (DOX)-induced cardiotoxicity has been widely observed, yet the specific impact on cardiac fibroblasts is not fully understood. Additionally, the modulation of the transforming growth factor beta (TGF-β) signaling pathway by DOX remains to be fully elucidated. This study investigated DOX's ability to modulate the expression of genes and proteins involved in the TGF-β signaling cascade in mouse fibroblasts from two sources by assessing the impact of DOX treatment on TGF-β inducible expression of pivotal genes and proteins within fibroblasts. Mouse embryonic fibroblasts (NIH3T3) and mouse primary cardiac fibroblasts (CFs) were treated with DOX in the presence of TGF-β1 to assess changes in protein levels by western blot and changes in mRNA levels by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR). Our results revealed a dose-dependent reduction in cellular communication network factor 2 (CCN2) protein levels upon DOX treatment in both NIH3T3 and CFs, suggesting an antifibrotic activity by DOX in these fibroblasts. However, DOX only inhibited the TGF-β1 induced expression of COL1 in NIH3T3 cells but not in CFs. In addition, we observed that DOX treatment reduced the expression of BMP1 in NIH3T3 but not primary cardiac fibroblasts. No significant changes in SMAD2 protein expression and phosphorylation in either cells were observed after DOX treatment. Finally, DOX inhibited the expression of Atf4 gene and increased the expression of Cdkn1a, Id1, Id2, Runx1, Tgfb1, Inhba, Thbs1, Bmp1, and Stat1 genes in NIH3T3 cells but not CFs, indicating the potential for cell-specific responses to DOX and its modulation of the TGF-β signaling pathway.

While DOX treatment diminished the extent of phosphorylation, the reduction did not reach statistical significance. DOX also inhibited the TGF-β1 induced expression of COL1 in NIH3T3 cells and CFs. Finally, DOX inhibited the TGF-β1 induced expression of Atf4 and increased the expression of Cdkn1a, Id1, Id2, Runx1, Tgfb1, Inhba, Thbs1, Bmp1, and Stat1 in NIH3T3 cells but not CFs, indicating the potential for cell-specific responses to DOX and its modulation of the TGF-β signaling pathway. Understanding the underlying mechanisms of the ability of DOX to modulate gene expression and signaling pathways in fibroblasts holds promise for future development of targeted therapeutic strategies to mitigate DOX-induced cardiotoxicity specifically affecting CFs.

Early detection of the impact of combined taxane and carboplatin treatment on autonomic nerves in patients with cervical cancer: Measurement of heart rate variability. Front Physiol 2023; 14:1126057. [PMID: 36926192 PMCID: PMC10011481 DOI: 10.3389/fphys.2023.1126057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Accepted: 02/20/2023] [Indexed: 03/08/2023] Open
Abstract
Background: Previous studies have shown that heart rate variability (HRV) analysis is a sensitive indicator of chemotherapy-induced cardiotoxicity. However, most studies to date have observed long-term effects using long-term analyses. The main purpose of this study was to evaluate the acute effect of chemotherapy on the cardiac autonomic nervous system (ANS) in patients with cervical cancer (CC) by examining short-term HRV. Methods: Fifty patients with CC admitted to the Department of Gynecology and Oncology of the First Affiliated Hospital of Bengbu Medical College were enrolled in the study. Based on their chemotherapy regimens, the patients were divided into a DC group (docetaxel + carboplatin) and a TC group (paclitaxel + carboplatin). A 5-min resting electrocardiogram (ECG) was collected before and the day after chemotherapy: the time domain (standard deviation of normal-to-normal intervals (SDNN) and root mean square of successive differences (RMSSD)) and frequency domain (low-frequency power (LF), high-frequency power (HF), and (LF/HF)) parameters were analyzed, and the differences before and after chemotherapy were compared. Results: The results showed that SDNN, RMSSD and HF were significantly higher in the DC and TC groups after chemotherapy than before (p < 0.05, Cohen's d > 0.5). In addition, LF was significantly higher after TC than before chemotherapy (p < 0.05, Cohen's d > 0.3), and LF/HF was significantly lower after DC than before chemotherapy (p < 0.05, Cohen's d > 0.5). Conclusion: Chemotherapy combining taxane and carboplatin can increase the HRV of CC patients in the short term, and HRV may be a sensitive tool for the early detection of chemotherapy-induced cardiac ANS perturbations.

Chem Biol Interact 2022; 363:110008. [PMID: 35667395 DOI: 10.1016/j.cbi.2022.110008] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Revised: 05/28/2022] [Accepted: 06/01/2022] [Indexed: 11/03/2022]
Abstract
Doxorubicin (DOX) is an effective antitumor drug; however, but its clinical application is seriously limited by the cardiotoxicity induced by its use. Recent studies have found that ferroptosis is an important mechanism underlying DOX-induced cardiotoxicity. However, existing studies are based on DOX-induced acute or subacute cardiotoxicity model. Therefore, we established a murine model of DOX-induced chronic cardiotoxicity using the clinically relevant cumulative dose, to evaluate the potential molecular mechanism underlying ferroptosis of cardiomycocytes. Male C57 mice were received intraperitoneal injections of DOX at a dose of 3 mg/kg body weight, once a week for 12 weeks. We dynamically analysed echocardiographic findings, serum myocardial enzyme levels, haematological indexes and cardiac histopathological changes. The results showed that, after receiving a cumulative DOX dose of 15 mg/kg, the mice developed anaemia and the function and structure of the heart changed significantly with an increase in the cumulative DOX dose. Importantly, with a cumulative DOX dose of 36 mg/kg, iron overload occurred in the heart tissue. Moreover, RNA-sequencing analysis and experimental verification revealed that ferropotosis is the underlying mechanism of DOX-induced chronic cardiotoxicity. Our results showed that DOX inhibits Slc7a11 in system-Xc, resulting in the reduction of GSH synthesis to prevent GPX4 from scavenging lipid peroxides. In addition, DOX induced the occurrence of ferroptosis via down-regulating Nrf2 expression to inhibit HO-1 and GPx4 levels. Our study provides a new perspective for evaluating the pathophysiology of DOX-induced chronic cardiotoxicity in the future, and developing new potential therapeutic strategies for the prevention and treatment of DOX-induced cardiotoxicity.

Abstract
Aim Clinical utility of doxorubicin (DOX) is limited by its cardiotoxic side effect, and the underlying mechanism still needs to be fully elucidated. This research aimed to examine the role of (pro)renin receptor (PRR) in DOX-induced heart failure (HF) and its underlying mechanism. Main Methods Sprague Dawley (SD) rats were injected with an accumulative dosage of DOX (15 mg/kg) to induce HF. Cardiac functions were detected by transthoracic echocardiography examination. The levels of lactate dehydrogenase (LDH) and creatine kinase (CK) in serum were detected, and oxidative stress related injuries were evaluated. Furthermore, the mRNA expression of PRR gene and its related genes were detected by real-time PCR (RT-PCR), and protein levels of PRR, RAC1, NOX4 and NOX2 were determined by Western blot. Reactive oxygen species (ROS) were determined in DOX-treated rats or cells. Additionally, PRR and RAC1 were silenced with their respective siRNAs to validate the in vitro impacts of PRR/RAC1 on DOX-induced cardiotoxicity. Moreover, inhibitors of PRR and RAC1 were used to validate their effects in vivo. Key Findings PRR and RAC1 expressions increased in DOX-induced HF. The levels of CK and LDH as well as oxidative stress indicators increased significantly after DOX treatment. Oxidative injury and apoptosis of cardiomyocytes were attenuated both in vivo and in vitro upon suppression of PRR or RAC1. Furthermore, the inhibition of PRR could significantly down-regulate the expressions of RAC1 and NOX4 but not that of NOX2, while the inhibition of RAC1 did not affect PRR. Significance Our findings showed that PRR inhibition could weaken RAC1-NOX4 pathway and alleviate DOX-induced HF via decreasing ROS production, thereby suggesting a promising target for the treatment of DOX-induced HF.

Monitoring of anthracycline-induced myocardial injury using serial cardiac magnetic resonance: An animal study. Int J Cardiol 2020; 328:111-116. [PMID: 33359332 DOI: 10.1016/j.ijcard.2020.12.040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 12/07/2020] [Accepted: 12/09/2020] [Indexed: 11/23/2022]
Abstract
PURPOSE To assess the feasibility of using comprehensive serial cardiovascular MR (CMR) to evaluate bilateral ventricle mechanical changes and myocardial tissue characteristics, as well as correlations between the serial CMR and histology in a beagle model of anthracycline-induced cardiotoxicity. METHODS This animal study was approved by the institutional review board. Serial CMR imaging was performed in a total of fifteen beagles at baseline (n = 15), at week 16 (n = 10) and week 24 (n = 7) post-anthracycline. Feature-tracking CMR (FT-CMR) was applied to measure bilateral ventricular (left ventricle (LV) and right ventricle (RV)) global peak strain including radial (GRS), circumferential (GCS) and longitudinal (GLS) strain. The changes in strain, LV/RV functional parameters, native T1, extracellular volume fraction (ECV) and collagen volume fraction (CVF) were calculated. RESULTS Compared to baseline at weeks 16 and 24, significantly decreases to LV-GLS and native T1 were observed, while ECV significantly increased (all P < 0.05). LVEF significantly decreased and LV-EDV/ESV significantly increased at week 16 compared to baseline (all P < 0.05), but no further progression was seen at week 24. RV-GLS significantly decreased at week 16, but no further progression was seen at week 24, while RVEF was different until week 24. CVF increased significantly during modeling. Native T1 and ECV showed positive correlation with CVF (r = 0.645, P < 0.001), while LV-GLS showed negative correlation with CVF (r = -0.736, P < 0.05). CONCLUSION Cardiotoxicity affects the RV slightly and less progressively than the LV. FT-CMR-based GLS, native T1 and ECV may potentially be used as imaging biomarkers for early monitoring of anthracycline-induced myocardial Injury.

Abstract
Anthracycline drugs are considered to be pivotal drugs in numerous chemotherapy regimens for breast cancer. However, the cardiotoxicity associated with the treatment is an important issue to be addressed. With the emergence of increasingly diverse antitumor drugs, anthracycline-free therapies are able to reduce the cardiotoxicity caused by anthracycline drugs while ensuring that a therapeutic effect is achieved. In the present review, anthracycline-free oncological therapy regimens for the treatment of patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer and the associated cardiovascular toxicity are discussed, as well as some monitoring strategies. It is recommended that patients with HER2-positive breast cancer patients should receive adjuvant chemotherapy with single or dual-targeted therapy, with or without endocrine therapy according to the hormone receptor status determined by immunohistochemical examination. The main side effects of targeted therapy include cardiac dysfunction, hypertension and arrhythmia. According to individual risk stratification, it is recommended that patients should be periodically monitored using echocardiography, electrocardiography and serum markers, to enable the timely detection of the cardiovascular adverse reactions associated with tumor treatment, thereby preventing the morbidity and mortality caused by the cardiotoxicity of these drugs.
