RAPH1 and breast cancer: Consistent with Lpd's predominant role at the plasma membrane in promoting cell motility and migration,17, 19, 20 we observed a significant association between highly, but not moderately, increased Lpd staining intensity at the plasma membrane and reduced disease-free (Histoscore 3: HR (95% CI): 1.652 (1.24–2.428)) and metastasis-free survival of breast cancer patients (Histoscore 3: HR (95% CI): 1.515 (1.054–2.178); Figure 1e compared with respective histoscore 1).
