In particular, Rab5, -11 and -27 were found increased in MDR cells in both models (Figure 1B) although this was only statistically significant for Rab5 and Rab11 in NSCLC cells and for Rab27 in CML cells (NSCLC: Rab5, 1.00 ± 0.0 vs. 1.31 ± 0.8, p ≤ 0.05; Rab11, 1.00 ± 0.0 vs. 1.49 ± 0.12, p ≤ 0.05; Rab27, 1.00 ± 0.0 vs. 1.58 ± 0.45; CML: Rab5, 1.00 ± 0.0 vs. 1.76 ± 0.46; Rab11, 1.00 ± 0.0 vs. 1.79 ± 0.61; Rab27, 1.00 ± 0.0 vs. 3.01 ± 0.33, p ≤ 0.05). Here, RAB5A is linked to non-small cell lung carcinoma.
