Construction of miRNA-miRNA networks revealing the complexity of miRNA-mediated mechanisms in trastuzumab treated breast cancer cell lines.

Trastuzumab is a monoclonal antibody frequently used to prevent the progression of HER2+ breast cancers, which constitute approximately 20% of invasive breast cancers. microRNAs (miRNAs) are small, non-coding RNA molecules that are known to be involved in gene regulation. With their emerging roles in cancer, they are recently promoted as potential candidates to mediate therapeutic actions by targeting genes associated with drug response.

Toscana virus (TOSV) exposure is confirmed in blood donors from Central, North and South/Southeast Anatolia, Turkey.

Toscana virus (TOSV), a sandfly fever virus serotype of medical and public health importance, is a major pathogen involved in aseptic meningtis occurring in Mediterranean countries and poses a threat to the residents as well as travellers. Limited data on TOSV activity are present from Turkey despite being located in the endemic zone. We aimed to identify TOSV exposure in 1115 healthy blood donors at the Hacettepe University Hospital Blood Bank in Ankara, Turkey, using commercial indirect fluorescence assays (IFAs) and virus neutralization test (VNT) for antibody detection and specificity confirmation.
