Premedication with pioglitazone prevents doxorubicin-induced left ventricular dysfunction in mice.

BMC Pharmacol Toxicol 2021 May 7;22(1):27. Epub 2021 May 7.

Department of Cardiovascular Medicine, Faculty of Medicine and Graduate School of Medicine, Hokkaido University, Kita-15, Nishi-7, Kita-ku, Sapporo, 060-8638, Japan.

Background: Doxorubicin (DOX) is widely used as an effective chemotherapeutic agent for cancers; however, DOX induces cardiac toxicity, called DOX-induced cardiomyopathy. Although DOX-induced cardiomyopathy is known to be associated with a high cumulative dose of DOX, the mechanisms of its long-term effects have not been completely elucidated. Pioglitazone (Pio) is presently contraindicated in patients with symptomatic heart failure owing to the side effects. Read More

Redd1 knockdown prevents doxorubicin-induced cardiac senescence.

Aging (Albany NY) 2021 May 6;13. Epub 2021 May 6.

Department of Geriatrics, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei 430022, China.

Regulated in development and DNA damage response-1 (Redd1) is a stress-response gene that is transcriptionally induced by diverse stressful stimuli to influence cellular growth and survival. Although evidence suggests that aging may drive Redd1 expression in skeletal muscles, the expression patterns and functions of Redd1 in senescent cardiomyocytes remain unspecified. To address this issue, and models of cardiomyocyte senescence were established by administration of doxorubicin (Dox). Read More

Mangiferin Inhibits Apoptosis in Doxorubicin-Induced Vascular Endothelial Cells via the Nrf2 Signaling Pathway.

Int J Mol Sci 2021 Apr 20;22(8). Epub 2021 Apr 20.

Department of Biochemistry, Saveetha Dental College, Saveetha Institute of Medical and Technical Sciences, Saveetha University, Chennai 600 077, India.

Doxorubicin increases endothelial permeability, hence increasing cardiomyocytes' exposure to doxorubicin (DOX) and exposing myocytes to more immediate damage. Reactive oxygen species are major effector molecules of doxorubicin's activity. Mangiferin (MGN) is a xanthone derivative that consists of C-glucosylxanthone with additional antioxidant properties.

Co-delivery of IOX1 and doxorubicin for antibody-independent cancer chemo-immunotherapy.

Nat Commun 2021 04 23;12(1):2425. Epub 2021 Apr 23.

Zhejiang Key Laboratory of Smart Biomaterials and Key Laboratory of Biomass Chemical Engineering of Ministry of Education, College of Chemical and Biological Engineering, Zhejiang University, Hangzhou, China.

Anti-programmed cell death-1 (PD-1)/programmed cell death-ligand 1 (PD-L1) antibodies are currently used in the clinic to interupt the PD-1/PD-L1 immune checkpoint, which reverses T cell dysfunction/exhaustion and shows success in treating cancer. Here, we report a histone demethylase inhibitor, 5-carboxy-8-hydroxyquinoline (IOX1), which inhibits tumour histone demethylase Jumonji domain-containing 1A (JMJD1A) and thus downregulates its downstream β-catenin and subsequent PD-L1, providing an antibody-independent paradigm interrupting the PD-1/PD-L1 checkpoint. Synergistically, IOX1 inhibits cancer cells' P-glycoproteins (P-gp) through the JMJD1A/β-catenin/P-gp pathway and greatly enhances doxorubicin (DOX)-induced immune-stimulatory immunogenic cell death.

Chinese Herbal Medicine, Guilu Erxian Glue, as Alternative Medicine for Adverse Side Effects of Chemotherapy in Doxorubicin-Treated Cell and Mouse Models.

Evid Based Complement Alternat Med 2021 5;2021:5548968. Epub 2021 Apr 5.

School of Life Science, National Taiwan Normal University, Taipei, Taiwan.

Doxorubicin (DOX), a chemotherapeutic drug, often causes many adverse side effects in patients with cancer, such as weight loss, motor disability, blood circulation defects, myelosuppression, myocardial injury, joint degeneration, and bone loss. The Chinese herbal medicine Guilu Erxian Glue (GEG) has been used in the prevention and treatment of osteoarthritis and osteoporosis for hundreds of years, with considerably fewer side effects. We expected that GEG could serve as a protective and beneficial alternative treatment for DOX-induced adverse side effects. Read More

Polyphenols from Arctium lappa L ameliorate doxorubicin-induced heart failure and improve gut microbiota composition in mice.

J Food Biochem 2021 Apr 17:e13731. Epub 2021 Apr 17.

College of Food Science and Engineering, Yangzhou University, Yangzhou, PR China.

In this study, the ameliorative effect of purified polyphenols from Arctium lappa L (ALPP) on doxorubicin (DOX)-induce heart failure was investigated. Results indicated that ALPP pretreatment significantly reduced the activities of casein kinase and lactate dehydrogenase, lowered the levels of inflammatory indexes (TNF-α and NO), and alleviated antioxidant stress in DOX-induce mice, thus leading to a reduced heart failure syndrome. In addition, according to 16s high-throughput sequencing, the increased abundance of Lactobacillaceae, Muribaculaceae, and Ruminococcaceae and the decreased abundance of Proteobacteria, Enterobacteriaee, and Escherichia_Shigella were observed in ALPP treatment group.

RB1CC1 functions as a tumor-suppressing gene in renal cell carcinoma via suppression of PYK2 activity and disruption of TAZ-mediated PDL1 transcription activation.

Cancer Immunol Immunother 2021 Apr 10. Epub 2021 Apr 10.

Department of Urology, First Affiliated Hospital, University of South China, No. 69, Chuanshan Road, Hengyang, 421001, Hunan Province, People's Republic of China.

Rb1-inducible coiled-coil 1 (RB1CC1) has been demonstrated to function as an inhibitor of proline-rich/Ca-activated tyrosine kinase 2 (PYK2) by binding to the kinase domain of PYK2, which promotes the proliferation, invasion, and migration of renal cell carcinoma (RCC) cells. Additionally, in breast cancer, PYK2 positively regulates the expression of transcriptional co-activator with PDZ-binding motif (TAZ) which in turn can enhance PDL1 levels in breast and lung cancer cells. The current study was performed to decipher the impact of RB1CC1 in the progression of RCC via regulation of the PYK2/TAZ/PDL1 signaling axis. Read More
