Autophagy has been implicated in the ageing process, but whether autophagy activation extends lifespan in mammals is unknown. Here we show that ubiquitous overexpression of Atg5, a protein essential for autophagosome formation, extends median lifespan of mice by 17.2%. We demonstrate that moderate overexpression of Atg5 in mice enhances autophagy, and that(More)
Prion protein (PRNP) has been implicated in various types of neurodegenerative diseases. Although much is known about prion diseases, the function of cellular PRNP remains cryptic. Here, we show that PRNP mediates amyloid β1–42 (Aβ42)-induced autophagy activation through its interaction with BECN1. Treatment with Aβ42 enhanced autophagy flux in neuronal(More)
Numerous studies have established a link between autophagy and aging; however, the relationship has not been clearly defined. Aging is a very complex process caused by the accumulation of various factors due to the gradual failure of cellular maintenance. Recent studies have shown that autophagy reduces the stress responses induced by starvation, reactive(More)
Existing evidence suggests a possible role of viruses in human bladder cancer development. Recently, Kaposi’s sarcoma-associated herpesvirus (KSHV) was reported to be the most frequently detected virus in bladder cancer tissue from Croatian patients on screening with the Lawrence Livermore Microbial Detection Array. In the current study, to investigate the(More)
Kaposi’s sarcoma-associated herpesvirus (KSHV) is the major etiologic agent of Kaposi’s sarcoma, primary effusion lymphoma, and multicentric Castleman’s disease. Recent studies have indicated that KSHV can be detected at high frequency in patient-derived bladder cancer tissue and might be associated with the pathogenesis of bladder cancer. Bladder cancer is(More)
