CML
bcr-abl hybrid |
Translocation of the two chromosomes creates the Philadelphia chromosome, which codes for a pathologic fusion protein (tyrosine kinase).
The protein is constitutively active and activates a number of cell cycle-controlling enzymes, effectively speeding up cell division. It also inhibits DNA repair. |

|
Burkitt's lymphoma
c-myc activation |
Places c-myc (transcription factor - protooncogene) under transcriptional control of the Ig heavy-chain promotor, which leads to overexpression
|

|
Follicular lymphoma
bcl-2 activation |
Places bcl-2 (anti-apoptosis) under transcriptional control of the Ig heavy-chain promotor, which leads to overexpression

AML - M3
responsive to all-trans retinoic acid |
The gene for the retinoic acid receptor (17) is transferred to be adjacent to the PML gene (15). Codes for a pathologic fusion protein that creates an abnormal retinoic acid receptor, and this inhibits myloblastic differentiation. This is why this leukemia can be treated with vitamin A.
