Fig. 2From: Differential mRNA expression of the main apoptotic proteins in normal and malignant cells and its relation to in vitro resistanceComparison of mRNA levels of selected genes among different tumour cells. Relative mRNA levels of p53, BAX, Bcl-XL and Bcl-2 gene in group of controls versus leukemia samples (a) and between groups of three different tumour samples—breast cancer, colorectal carcinoma and lung cancer samples (b). mRNA level of each gene is normalized to β-actin level. Error bars represent SD. **p < 0.01, ***p < 0.001. CaCo colorectal carcinoma, BCa breast carcinoma, LCa lung carcinomaBack to article page
