Rhabdomyosarcoma (RMS) is an aggressive soft tissue cancer characterized by disturbed myogenic differentiation. Here we report a role for the oxidative stress response factor HO-1 in progression of RMS. We found that HO-1 was elevated and its effector target miR-206 decreased in RMS cell lines and clinical primary tumors of the more aggressive alveolar phenotype (aRMS). In embryonal RMS (eRMS), HO-1 expression was induced by Pax3/7-FoxO1, an aRMS hallmark oncogene, followed by a drop in miR-206 levels. Inhibition of HO-1 by tin protoporphyrin (SnPP) or siRNA downregulated Pax3/7-FoxO1 target genes and induced a myogenic program in RMS...

Despite the recent findings concerning pathogenesis and novel therapeutic strategies, the mortality rate in patients with acute kidney injury (AKI) remains very high. Early detection of patients with impaired renal function may help to ensure more aggresive treatment and to improve clinical outcome. Serum creatinine is still gold standard of kidney injury, although it is well known as an insensitive and unreliable biomarker (for example, its concentration does not increase significantly until about half of the kidney function is lost)...
