Semiquantitative RT–PCR. Ratio of NGF, TrkA, and p75NTR mRNA expression in the tumour portion (T) and corresponding normal epithelium (N) in 19 OESCC patients (T/N ratio) was examined. In 89% (17 of 19) of the patients, NGF mRNA levels were higher in the tumour portion and in 84% (16 of 19) TrkA mRNA levels were higher; 42% (eight of 19) of the pateints had lower p75NTR mRNA levels in the tumour portion.
