Diffuse dermal angiomatosis: a rare cause of painful ulceration in renal insufficiency.

Diffuse dermal angiomatosis is a rare, benign, reactive cutaneous vascular proliferation that has been reported in the context of end-stage renal failure and can rarely be associated with arteriovenous fistulas. We report a striking clinical resolution following prompt diagnosis and subsequent arteriovenous fistula reversal. This case further demonstrates that accurate diagnosis is particularly rewarding since correct therapeutic approach can be curative.

Treatment of Polarized Cystic Fibrosis Airway Cells With HGF Prevents VX-661-Rescued F508del-CFTR Destabilization Caused by Prolonged Co-exposure to VX-770.

Cystic fibrosis (CF), the most common inherited disease in Caucasians, is caused by mutations in CFTR, the most frequent of which is F508del. F508del causes ER retention and degradation of the mutant CFTR protein, but also defective channel gating and decreased half-life at the plasma membrane. Despite the recent successes with small-molecule CFTR modulator drugs, the folding-corrector/gating-potentiator drug combinations approved for CF individuals carrying F508del-CFTR have sometimes produced severe side effects.

Arginine and Arginases Modulate Metabolism, Tumor Microenvironment and Prostate Cancer Progression.

Arginine availability and activation of arginine-related pathways at cancer sites have profound effects on the tumor microenvironment, far beyond their well-known role in the hepatic urea cycle. Arginine metabolism impacts not only malignant cells but also the surrounding immune cells behavior, modulating growth, survival, and immunosurveillance mechanisms, either through an arginase-mediated effect on polyamines and proline synthesis, or by the arginine/nitric oxide pathway in tumor cells, antitumor T-cells, myeloid-derived suppressor cells, and macrophages. This review presents evidence concerning the impact of arginine metabolism and arginase activity in the prostate cancer microenvironment, highlighting the recent advances in immunotherapy, which might be relevant for prostate cancer.
