ALDH1A1 and breast cancer: Moreover, the expression of CPT1C was positively correlated with several CSC markers (CPT1C vs. ALDH1A1, R=0.27, P<0.0001; CPT1C vs. ALDH1A2, R=0.25, P<0.0001; CPT1C vs. ALDH1A3, R=0.2, P<0.0001; CPT1C vs. PROM1, R=0.12, P<0.0001; Figure 3G) in breast cancer patients, further suggesting an important role of CPT1C in maintaining cancer stemness.
