Our RT-PCR assays of normal and endometrial cancer cells captured by LCM (Figure 1A) revealed that mRNA transcript levels of TrkB appeared to be higher in the tumors than in the normal specimens, but overall the difference in TrkB mRNA expression between endometrial cancer tissues and the normal endometrium was not statistically significant (P > 0.05) (Figure 1B). This evidence concerns the gene NTRK2 and endometrial cancer.
