Figure 4 (A) Cell lysates or untreated cocultured with Helicobacter pylori strains 60190 or Tx30a, blotted to β‐catenin. Bands are fainter with coculture, particularly for 60190. Duplicate experiments were run in parallel are shown. (B) HT29 lysates blotted to E‐cadherin. Three different ratios of bacteria:cell have no effect on the amount of total E‐cadherin. (C) HT29 lysates blotted to β‐catenin. The total amount of β‐catenin is seen to reduce as bacterial density increases. Total protein loading was equal in each lane in (A), (B) and (C).
