            The ALK(F1174L) mutation potentiates the oncogenic activity of MYCN in neuroblastoma.

            The ALK(F1174L) mutation is associated with intrinsic and acquired resistance to crizotinib and cosegregates with MYCN in neuroblastoma. In this study, we generated a mouse model overexpressing ALK(F1174L) in the neural crest. Compared to ALK(F1174L) and MYCN alone, co-expression of these two oncogenes led to the development of neuroblastomas with earlier onset, higher penetrance, and enhanced lethality. ALK(F1174L)/MYCN tumors exhibited increased MYCN dosage due to ALK(F1174L)-induced activation of the PI3K/AKT/mTOR and MAPK pathways, coupled with suppression of MYCN pro-apoptotic effects. Combined treatment with the ATP-competitive mTOR inhibitor Torin2 overcame the resistance of ALK(F1174L)/MYCN tumors to crizotinib. Our findings demonstrate a pathogenic role for ALK(F1174L) in neuroblastomas overexpressing MYCN and suggest a strategy for improving targeted therapy for ALK-positive neuroblastoma.

              Safety and efficacy of phage therapy in difficult-to-treat infections: a systematic review

              According to the latest reports from WHO, the incidence of antibiotic-resistant bacterial infections is increasing worldwide, resulting in increased morbidity and mortality and a rising pressure on health-care systems. However, the development of new antibiotics is an expensive and time-consuming process, urging scientists to seek alternative antimicrobial strategies. Over the past few decades, the concept of therapeutic administration of bacteriophages (also known as phages) has gained popularity worldwide. Although conceptually promising, the widespread implementation of phage therapy in routine clinical practice is restricted by the scarcity of safety and efficacy data obtained according to the strict standards of the applicable clinical trial regulations. In this systematic review, we list clinical data published between Jan 1, 2000 and Aug 14, 2021 on the safety and efficacy of phage therapy for difficult-to-treat bacterial infections, and provide an overview of trials and case studies on the use of phage therapy in several medical disciplines.
