Expression analysis of the E-cad gene.

(A) E-cadherin and transferrin receptor RT-PCR products were amplified from bone marrow samples from normal donors and patients with AML. (B) E-cadherin and transferrin receptor RT-PCR products were amplified from blood samples from normal donors and patients with CLL. E-cadherin PCR product is 310bp, and the transferrin receptor PCR product is 323 bp. The sample numbers are labeled above each lane (R, leukemic patient; N, normal sample). The relative amount of E-cadherin expression versus transferrin receptor expression (E-cad/transferrin) is expressed in the graph.
