MYC and leukemia: On the other hand, some studies present that the WMFs (weak magnetic field) affect the biological system; for example, Lacy-Hulbert et al. (1995) presented that WMF exposure affected human leukemia cells that demonstrated higher levels of the transcription factor c-Myc (major effect of c-Myc is B cell proliferation and has been associated with B cell malignancies) [10,11,12].
