Prognostic significance of miR-34a in Ewing sarcoma is associated with cyclin D1 and ki-67 expression.

2014

ABSTRACT Background At diagnosis, identification of reliable biological indicators of prognosis to allow stratification of patients according to different risks is an important but still unresolved aspect in the treatment of Ewing sarcoma (EWS) patients. This study aimed to explore the role of miR-34A expression on prognosis of EWS patients. Patients and methods Specimens from 109 patients with non-metastatic EWS treated at the Rizzoli Institute with neoadjuvant chemotherapy (protocols ISG/SSGIII, EW-1, EW-2, EW-REN2, EW-REN3, EW-PILOT) and 17 metastases were studied. Sixty-eight patients (62%) remained disease-free and 41 (38%) relapsed (median follow-up: 67 months, range 9–241 months). Ex…

Prognostic and predictive biomarkers for targeted therapy in NSCLC: For whom the bell tolls?

2015

Introduction: The discovery of molecular biomarkers and the advent of targeted therapies have led to a radical change in the treatment of several tumors, including NSCLC. In the last few years, the number of molecular biomarkers has rapidly increased, and a growing interest has been recently focused on their potential prognostic and predictive value in clinical settings. Areas covered: This review describes all the molecular biomarkers with prognostic and predictive value in NSCLC, including both clinically approved biomarkers, and emerging biomarkers under investigation in clinical trials. Liquid biopsy and applications of circulating biomarkers are also described. Expert opinion: The onco…

Recent Patents on Oxidative Stress-Related Biomarkers in Chronic Heart Failure: The Central Role of Endothelium and Myeloperoxidase

2013

Endothelial cells are key modulators of multiple physiological processes, and their impairment may result in the generation of endothelial dysfunction and ultimately cardiovascular diseases. Under physiologic conditions, reactive oxygen and nitrogen mediators of endothelial cells act to propagate signals driven by different stimuli, by forming molecules with a longer half-life like hydrogen peroxide. Reactive oxygen species (ROS) are constantly produced as a consequence of aerobic metabolism. Under physiologic conditions, their tendency to cause oxidative damage is counterbalanced by the action of antioxidants or oxidant-scavenging enzymes. An imbalance in favour of oxidants leads to oxidat…
