Group A Rotavirus Associated with Encephalitis in Red Fox.

In 2011, a group A rotavirus was isolated from the brain of a fox with encephalitis and neurologic signs, detected by rabies surveillance in Italy. Intracerebral inoculation of fox brain homogenates into mice was fatal. Genome sequencing revealed a heterologous rotavirus of avian origin, which could provide a model for investigating rotavirus neurovirulence.

Detection of coronaviruses in bats of various species in Italy.

Bats are natural reservoirs for many mammalian coronaviruses, which have received renewed interest after the discovery of the severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS) CoV in humans. This study describes the identification and molecular characterization of alphacoronaviruses and betacoronaviruses in bats in Italy, from 2010 to 2012. Sixty-nine faecal samples and 126 carcasses were tested using pan-coronavirus RT-PCR.

MicroRNA-23b mediates urokinase and c-met downmodulation and a decreased migration of human hepatocellular carcinoma cells.

Urokinase-type plasminogen activator (uPA) and c-met play a major role in cancer invasion and metastasis. Evidence has suggested that uPA and c-met overexpression may be coordinated in human hepatocellular carcinoma (HCC). In the present study, to understand whether the expression of these genes might be coregulated by specific microRNAs (miRs) in human cells, we predicted that Homo sapiens microRNA-23b could recognize two sites in the 3'-UTR of uPA and four sites in the c-met 3'-UTR by the algorithm pictar.
