TFPI2 and neoplasm: Similarly, analysis of total RNA from breast cancer and matched adjacent normal tissue from five individuals revealed the presence of TFPI-2as transcripts in two tumours (Figure 1C, upper panel; T1 and T3) that we have previously shown to express LCT13 (22), and in these cases, reduced TFPI-2 expression was also observed (Figure 1C, lower panel).
