Of note, increased P2RY2 mRNA levels have also been detected in gastric cancer biopsies from 14 patients (as compared to the adjacent healthy mucosa) (146), but these findings do not allow to determine whether gastric neoplasms were infiltrated by P2RY2+ immune cells or whether they overexpressed P2RY2. The gene discussed is P2RY2; the disease is gastric neoplasm.
