Figure 7From: ID helix-loop-helix proteins as determinants of cell survival in B-cell chronic lymphocytic leukemia cells in vitro Relation between in vitro chlorambucil resistance and ID protein expression levels in 14 CLL samples. Data for relative ID expression levels and IC50 values are given in Figure 5B in the main manuscript. The left-hand plots show linear regression analysis where samples are coded according to ID protein expression range (open triangles: lowest 25th percentile; open squares: highest 75th percentile; solid diamonds: remaining samples). The right-hand plots show a comparison of ID protein expression levels between samples grouped according to percentile range of ID protein expression. Significant (<0.05) P values, calculated by Student’s t-test, are indicated in bold-face.Back to article page
