Over 180.000 SARS-COV-2 positive cases have been confirmed in Italy as April 20, with the number of deaths exceeding 23 thousand, making Italy the second Country for world COVID-19 deaths. Such enormous occurrence of infected and dead people raises the urgent demand of effective fast available treatments to control and diminish this pandemic. Discovering the cellular/molecular mechanisms of SARS-COV-2 pathogenicity is of paramount importance to understand how the infection becomes a disease and for therapeutically approaching it. From literature data, through a bioinformatics approach, an in silico analysis was performed, to predict the putative virus targets and evidence the already available therapeutics. Literature experimental results identified angiotensin-converting enzyme ACE and Spike proteins particularly involved in COVID-19. We thus investigate on the signaling pathways modulated by the two proteins through query miRNet, the platform linking miRNAs, targets and functions. We predicted microRNAs (miRs), miR-335-5p and miR-26b-5p, as being modulated by Spike and ACE together with deacetylate histones pathway HDAC. Our results matched with the available clinical data. We hypothesize the current and EMA-approved, SARS-COV-2 off-label, HDAC inhibitors (HDACis) drugs may be repurposed to limit or block host-virus interactions. A ranked list of compounds is given that can be tested. |
