Cell response to extremely weak static magnetic fields
The effect of an extremely weak static magnetic field (EWSMF) was studied in diploid fibroblast strains that originated from a healthy donor and an ataxia telangiectasia patient. Indirect immunofluorescence was used to detect p53, p53BP1, and p21. The pattern that occurred in donor cells exposed to EWSMF similar to that observed in DNA damage, viz. the p53 and p21 levels increased and p3BP1 foci formed. No visible change was observed in primary fibroblasts from the ataxia telangiectasia patient. The results implicate ATM signaling in the fibroblast response to EWSMF.
