Redox Biology 2014 - Cancer Therapy, Redox Enzymology
Redox Biology Recent advances in the biochemistry of redox-active species and radicals are beginning to be translated into improvements in prevention and treatment of cancer. Traditionally, reactive species such as superoxide, hydrogen peroxide and nitric oxide (NO) are associated with toxicity; however, NO is useful in the treatment of angina and cardiovascular disease. Also, NO is involved in cancer tumor angiogenesis and apoptosis of cancer cells. This course is an overview presenting how redox-active species and radicals are generated; their effects on the cellular and physiological level, how they alter carcinogenesis, angiogenesis and proliferation in animal models of cancer, and how NO alters patient imaging profiles and response to cancer therapy. It consists of two 1-hour lectures with ample time for discussion and analysis. The participation of postdoctoral and clinical fellows interested in redox biology is encouraged.

Cardiorenal complications of immune checkpoint inhibitors, Published online: 16 July 2018; doi:10.1038/s41581-018-0035-1Immune checkpoint inhibitors (ICIs) have led to a paradigm shift in cancer therapy; however, these agents can induce immune-related adverse events (irAEs) in off-target organs. This Review describes the mechanism of action of ICI therapies and how these agents induce irAEs in the kidney and heart.
Bullous disorders associated with anti-PD-1/PD-L1 therapy are increasingly reported and may pose distinct therapeutic challenges. Their frequency and impact on cancer therapy are not well established.
Intratumoral androgen biosynthesis is one of the mechanisms involved in the progression of prostate cancer, and an important target for novel prostate cancer therapies. Using gas chromatography-tandem mass spectrometry and genome-wide RNA sequencing, we have analyzed androgen concentrations and androgen-regulated gene expression in cancerous and morphologically benign prostate tissue specimens and serum samples obtained from 48 primary prostate cancer patients. Intratumoral dihydrotestosterone (DHT) concentrations were significantly higher in the cancerous tissues compared to benign prostate (P
Abstract Throughout various eras of breast cancer therapy, postmastectomy radiation therapy (PMRT) has played an important role in the treatment of locally advanced breast cancer. PMRT decreases locoregional recurrence and may improve overall survival in patients with tumors over 5 cm or positive lymph nodes. As novel cancer therapies improve survival in breast cancer, the role of radiation therapy is evolving. Individualized recommendations for PMRT dependent on pathologic response after neoadjuvant systemic therapy are under investigation. This review summarizes the role of PMRT during breast cancer therapy...
