A qRT-PCR analysis of TINCR expression (left) of MM13 and MM2 PDX cells infected with lentiviral vectors expressing full-length TINCR cDNA. PDX cells infected with empty vector (Empty) were used as control. TINCR RNA levels relative to L32P housekeeping gene and control (mean±sd) from three biological replicates are shown. Statistical analyses were performed using Student t -test (***: p<0.001).
