Fig 2: Gene expression of prostate human cell lines for GNRH and its receptor subtypes 1 and 2.(A) GNRH1, (B) GNRHR1, (C) GNRH2, and (D) GNRHR2. The white bars show normal cells and the black bars show hyperplasia or cancer cells. Results are presented as a ratio between the target gene relative to the reference gene normalized to the levels of the control. Results shown are means ± standard error from 3 independent experiments performed in triplicates.
