1 There was a substantial decrease in c-myc mRNA levels when 100 microg/ml bestatin was added to 10 nmol/L ATRA (P < 0.05). Tretinoin MYC proto-oncogene, bHLH transcription factor Homo sapiens
2 Various concentrations (50, 75, 100 microg/ml) of bestatin combined with 10 nmol/L ATRA down-regulated the expression of c-Myc protein, which was negatively correlated with the NBT reduction activity of NB4 cells induced by 10 nmol/L ATRA alone or plus bestatin at various concentrations (r = -0.940, P = 0.017). Tretinoin MYC proto-oncogene, bHLH transcription factor Homo sapiens
3 Various concentrations (50, 75, 100 microg/ml) of bestatin combined with 10 nmol/L ATRA down-regulated the expression of c-Myc protein, which was negatively correlated with the NBT reduction activity of NB4 cells induced by 10 nmol/L ATRA alone or plus bestatin at various concentrations (r = -0.940, P = 0.017). Tretinoin MYC proto-oncogene, bHLH transcription factor Homo sapiens
4 It is concluded that an aminopeptidase inhibitor bestatin can potentiate ATRA-inducing differentiation of NB4 cells, possibly by down-regulating c-myc expression in synergy with ATRA. Tretinoin MYC proto-oncogene, bHLH transcription factor Homo sapiens
