BCL2L2 and lymphoma: It was previously reported that the absence of BCL-W substantially and significantly delayed lymphoma development in Eμ-Myc mice, with Eμ-MycT/+;Bcl-w+/+ mice all having succumbed to lymphoma before the first Eμ-MycT/+;Bcl-w−/− mouse even fell ill, and the Eμ-MycT/+;Bcl-w−/− mice survived upwards of 3 times longer than the controls [25].
