Update on a tumor-associated NADH oxidase in gastric cancer cell growth

Figure 1 Tumor-associated NADH oxidase protein expressions in different human gastric cancer lines. Aliquots of cell lysates were separated by SDS-PAGE and analyzed for tNOX expression by western blot analysis. β-Actin was used as an internal control to monitor for equal loading. Gastric cancer cell lines including, AGS (gastric adenocarcinoma), TMC-1 (derived from the lymph node of a moderately differentiated stomach adenocarcinoma), MKN45 (from the lymph node of a moderately differentiated stomach adenocarcinoma), SNU-1 (from a poorly differentiated primary carcinoma of the stomach), TMK-1 (from a poorly differentiated adenocarcinoma), and SCM (human gastric carcinoma), were used to study the expression of tNOX protein. SDS-PAGE: Sodium dodecyl sulfate polyacrylamide gel electrophoresis; tNOX: Tumor-associated NADH oxidase.
