BCAR1 and neoplasm: Additionally, our study in vivo demonstrated that BCAR1 levels were significantly and inversely correlated with tumor differentiation, by either counting positive percents of cells (Kruskal-Wallis test, P = 0.010) or evaluating stained intensity (achromasy = 0, stramineous = 1, buffy = 2, brown = 3; Kruskal-Wallis test, P = 0.014).
