Figure Lengend Snippet: Purinergic receptor pattern expression in normal and cancer-derived cell lines. (A) Representative polymerase chain reaction (PCR) from total RNA obtained from AGS (2) or GES-1 (3) cells for P2X receptors (P2XRs) (left) and P2Y receptors (P2YRs) (right). Lane 1 represents a blank control; the data shown is representative of at least three separate experiments. (B) Summary of quantitative PCR (qPCR) experiments showing RNA levels of P2X4R and P2X7R (left graph) or P2Y 1 R, P2Y 2 R, and P2Y4R (right graph) in control GES-1 cells or in gastric cancer (GC)-derived AGS, MKN-45, or MKN-74 cells. * p < 0.05, Kruskal–Wallis and Dunn´s tests. (C) Western blot analysis for the expression of P2X4R, P2X7R, P2Y 1 R, P2Y 2 R, and β-actin in HEK293, AGS, and GES-1 cells. Blots are representative of three different experiments.
Article Snippet: Membranes were blocked with buffer [5% nonfat dry milk in Tris-buffered saline (TBS) with 0.05% Tween-20 (TBS-T)] at room temperature for 1 h. Blots were incubated with primary antibodies against P2X4R, P2X7R, P2Y 2 R, P2Y 1 R (Alomone Labs, Jerusalem, Israel), and β-actin (Sigma-Aldrich, St. Louis, MO, USA) at 4°C overnight.
