A 5′-DIG and 3′-DIG-labeled, locked nucleic acid-incorporated miRNA probe (miRCURY LNATM Detection probe, Exiqon, Woburn, MA, USA) was applied for the detection of miR-323a-3p in BCa TMAs. The probe sequence of hsa-mir-323a-3p was designed as follows: 5′-AGAGGTCGAC CGTGTAATGTG-3′. The specific manipulations were performed as previously described.48 (link) Both the intensity and proportion of positive cells were considered for the semi-quantification of the strength of positivity.
