View Original AbstractCell phone use showed no detectable stress markers in parotid glands, but exposure levels weren't specified.
Plain English Summary
Researchers studied whether cell phone use causes stress-related changes in the parotid salivary glands (located near the ear where phones are held) by comparing saliva from 62 people's exposed and unexposed glands. They found no differences in cellular stress markers, protein levels, or salivary flow between the phone-exposed side and the opposite side, even when accounting for years of use or calling time.
Study Details
We investigated in the parotid glands whether cell phone use alters the expression of gene products related to cellular stress.
We used the saliva produced by the parotid glands of 62 individuals to assess molecular alterations ...
No difference was found for any of these parameters, even when grouping individuals by period of cel...
We provide molecular evidence that the exposure of parotid glands to cell phone use does not alter parotid salivary flow, protein concentration, or levels of proteins of genes that are directly or indirectly affected by heat-induced cellular stress.
