(A) RT-PCR analysis of the expression of Notch target genes in the AKR1 and AKR1010 thymomas and the 2B4.11 T cell hybridoma. Equivalent amounts of cDNA prepared from control and NotchIC expressing cells were serially diluted 5-fold and amplified using primers specific to the indicated genes. PCR products were analyzed by Southern blotting using specific probes.
(B) RT-PCR analysis of the expression of Notch target genes in DP thymocytes from NotchIC and littermate control mice. DP thymocytes were sorted from NotchIC and littermate control mice.
(C) RT-PCR analysis of the expression of Notch1 target genes in thymocyte subsets. Thymocyte subsets were sorted from B6 mice.
(D) RT-PCR analysis of the expression of Notch1 target genes in peripheral T cells. CD4+ and CD8+ T cells were sorted from peripheral lymph nodes of B6 mice.
