Despite carefully repeated experiments (n = 5 [at least], on each of the cell lines) testing whether the STX agents act mechanistically on the same pathways on which we found them to be very effective on growth and apoptosis in human NF1 tumour cell lines, we currently have been able to detect NO significant effects of either of the agents on the growth, morphology of NF2 cell lines through the pathways that are known to be important for the growth of or cell death in NF1 human tumour cell lines (as detailed in Shen et al., 2015 [30]). Here, NF2 is linked to neoplasm.
