ALB and neoplasm: Formalin-fixed, paraffin-embedded (FFPE) tissues were analyzed from 24 dogs with histologically confirmed HSA (18 splenic, six cardiac) and 12 non-neoplastic controls (six cardiac and six splenic).<h4>Results</h4>A total of 67 and 71 miRNAs were differentially expressed (DE) in splenic and cardiac HSA, respectively, with 18 miRNAs shared between both tumor types.
