Exposure to an extremely low-frequency electromagnetic field only slightly modifies the proteome of Chromobacterium violaceum ATCC 12472 Genet. Mol. Biol.
Baraúna,Rafael A.; Santos,Agenor V.; Graças,Diego A.; Santos,Daniel M.; Ghilardi Júnior,Rubens; Pimenta,Adriano M. C.; Carepo,Marta S. P.; Schneider,Maria P.C.; Silva,Artur.
Several studies of the physiological responses of different organisms exposed to extremely low-frequency electromagnetic fields (ELF-EMF) have been described. In this work, we report the minimal effects of in situ exposure to ELF-EMF on the global protein expression of Chromobacterium violaceum using a gel-based proteomic approach. The protein expression profile was only slightly altered, with five differentially expressed proteins detected in the exposed cultures; two of these proteins (DNA-binding stress protein, Dps, and alcohol dehydrogenase) were identified by MS/MS. The enhanced expression of Dps possibly helped to prevent physical damage to DNA. Although small, the changes in protein expression observed here were probably beneficial in helping the...
