HepatomiRNoma: The proposal of a new network of targets for diagnosis, prognosis and therapy in hepatocellular carcinoma

Abstract: The diagnosis and treatment of hepatocellular carcinoma (HCC) underwent a huge advancement in the last years. Recently, microRNAs (miRNAs) have been also studied to provide a new tool for early diagnosis of high risk patients, for prognostic classification to identify those patients who benefit cancer treatment and for predictive definition to select the right targeted drug. In this review we revised all the available data obtained to explore the role of miRNAs in HCC. This analysis led to identification of miRNAs which could gain a diagnostic, prognostic or predictive role. The results of studies on miRNAs involved in HCC are initial and far from providing scientific evidences to…

The synergistic effect of SAHA and parthenolide in MDA-MB231 breast cancer cells

Abstract: The sesquiterpene lactone Parthenolide (PN) exerted a cytotoxic effect on MDA-MB231 cells, a triple-negative breast cancer (TNBC) cell line, but its effectiveness was scarce when employed at low doses. This represents an obstacle for a therapeutic utilization of PN. In order to overcome this difficulty we associated to PN the suberoylanilide hydroxamic acid (SAHA), an histone deacetylase inhibitor. Our results show that SAHA synergistically sensitized MDA-MB231 cells to the cytotoxic effect of PN. It is noteworthy that treatment with PN alone stimulated the survival pathway Akt/mTOR and the consequent nuclear translocation of Nrf2, while treatment with SAHA alone induced autophagi…

Curcumin induces selective packaging of miR-21 in exosomes released by Chronic Myelogenous Leukemia cells

Effects of exosomes released by NSCLC cells on osteoclasts differentiation.

Effects of exosomes released by NSCLC cells on osteoclasts differentiation Pucci M., Taverna S., Corrado C., Giallombardo M., Rolfo C. and Alessandro R. Non-small cell lung cancer (NSCLC) has a poorly 5-year survival rate, as a consequence of the delay in the detection of the disease. The majority of patients are diagnosed in an advanced disease stage. Bone metastasis is the most frequent complication in NSCLC resulting in osteolytic lesions. The perfect balance between bone-resorbing osteoclasts (OCs) and bone-forming osteoblasts (OBs) activity is lost in bone metastasis, inducing osteoclastogenesis. Most of the patients with lung cancer are treated with EGFR inhibitors (TKIs). Numerous st…
