The discrepancies in the results obtained by different authors in tissue material from patients with adenoma and CRC may occur for various reasons, including the number and size of CRC samples tested, the primary antibodies used (rabbit/goat anti-human), all being polyclonal and not monoclonal, the suppliers they were sourced from (e.g., Chemicon, Phoenix Pharmaceuticals, Santa Cruz, ABCAM), the lack of differentiation between the types of ghrelin receptors tested, different scoring systems used to assess the intensity of expression, and more. The gene discussed is GHSR; the disease is adenoma.
