CTSB and neoplasm: Table 2 shows that TNBC MDA-MB-231 cells overexpress Cathepsin B (140–150 ng/mg) while, normal MCF-10A cells express low Cathepsin B (~ 2–8 ng/mg). The incubation of AMP-001/002/003 resulted a significant cell death in TNBC cells compared to normal cells (~ 10–12 times) confirming the earlier IC-50 results. Cathepsin B expression in tumor cells was measured using assay described by Pratt et.al [27].
