Cardiac complications of cancer therapies.

Adv Cancer Res 2022 20;155:167-214. Epub 2022 Apr 20.

Division of Cardiology, Department of Internal Medicine, Virginia Commonwealth University, Pauley Heart Center, Richmond, VA, United States. Electronic address:

The quest of defeating cancer and improving prognosis in survivors has generated remarkable strides forward in research and have advanced the development of new antineoplastic therapies. These achievements, combined with rapid screening and early detection, have considerably extended the life expectancy of patients surviving multiple types of malignancies. Consequently, chemotherapy-related toxicity in several organ systems, especially the cardiovascular system, has surfaced as one of the leading causes of morbidity and mortality among cancer survivors.

An overview of chemotoxicity and radiation toxicity in cancer therapy.

Adv Cancer Res 2022 30;155:1-27. Epub 2022 Apr 30.

Department of Pharmacology and Toxicology, Virginia Commonwealth University School of Medicine, Richmond, VA, United States. Electronic address:

While immunotherapy and targeted therapies represent major advances against different types of malignancies, the mainstay of cancer therapy continues to be radiation and surgery for localized disease, and chemotherapy for systemic disease, with the preponderance of chemotherapeutic agents (such as anthracyclines, alkylating agents, and antimetabolites) having been developed decades ago. Combination chemotherapy regimens have changed the natural history of once deadly diseases such as breast and prostate cancer and led to curative regimens in advanced hematological malignancies and testicular cancer. However, while oncologists maintain their focus on disease suppression, and where feasible, disease eradication, obstacles to achieving cure remain, such as tumor dormancy and ultimately disease recurrence, as well as both intrinsic and acquired resistance.

Since their discovery in 1993, microRNAs (miRNAs, miRs) have emerged as important regulators of many crucial cellular processes and their dysregulation have been shown to contribute to multiple pathological conditions, including cardiovascular disease (CVD). miRNAs have been found to regulate the expression of various genes involved in cardiac development and function, and in the development and progression of CVD. Many miRNAs are master regulators fine-tuning the expression of multiple, often interrelated, genes involved in inflammation, apoptosis, fibrosis, senescence, and other processes crucial for the development of different forms of CVD.

The epoxy fatty acid pathway enhances cAMP in mammalian cells through multiple mechanisms.

Prostaglandins Other Lipid Mediat 2022 Jun 29:106662. Epub 2022 Jun 29.

Department of Entomology and Nematology, and Comprehensive Cancer Center, University of California - Davis, Davis CA, USA. Electronic address:

The cellular mechanism by which epoxy fatty acids (EpFA) improves disease status is not well characterized. Previous studies suggest the involvement of cellular receptors and cyclic AMP (cAMP). Herein, the action of EpFAs derived from linoleic acid (LA), arachidonic acid (ARA), and docosahexaenoic acid on cAMP levels was studied in multiple cell types to elucidate relationships between EpFAs, receptors and cells' origin.

Kidney targeting of formoterol containing polymeric nanoparticles improves recovery from ischemia reperfusion-induced acute kidney injury in mice.

Kidney Int 2022 Jun 29. Epub 2022 Jun 29.

The University of Arizona R. Ken Coit College of Pharmacy, Skaggs Pharmaceutical Sciences Center, 1703 E. Mabel St. 85721, Tucson, AZ. USA; The University of Arizona College of Medicine, 501 N Campbell Ave. 85724, Tucson, AZ. USA; The University of Arizona, BIO5 Institute, 1657 E Helen St. 85719, Tucson, AZ. USA; Southern Arizona VA Health Care System, USA. Electronic address:

The β adrenergic receptor agonist, formoterol, is an inducer of mitochondrial biogenesis and restorer of mitochondrial and kidney function in acute and chronic models of kidney injury. Unfortunately, systemic administration of formoterol has the potential for adverse cardiovascular effects, increased heart rate, and decreased blood pressure. To minimize these effects, we developed biodegradable and biocompatible polymeric nanoparticles containing formoterol that target the kidney, thereby decreasing the effective dose, and lessen cardiovascular effects while restoring kidney function after injury.

The entrance route: oral, mucous, cutaneous, or systemic has a marked influence on the outcome of Trypanosoma cruzi experimental infection.

Acta Trop 2022 Jun 29:106581. Epub 2022 Jun 29.

Núcleo de Pesquisa em Ciências Biológicas, Universidade Federal de Ouro Preto, Campus Universitário, Morro do Cruzeiro - Ouro Preto, Minas Gerais, Brasil.

Catheter Ablation for Patients with Atrial Fibrillation and Heart Failure: Insights from the Swedish Heart Failure Registry.

Eur J Heart Fail 2022 Jul 2. Epub 2022 Jul 2.

Heart and Vascular Theme, Karolinska University Hospital, Stockholm, Sweden.

Aims: To investigate the association between catheter ablation for atrial fibrillation (AF) and mortality as well as hospitalization for heart failure (HF) in patients with HF across the ejection fraction (EF) spectrum.
