Heat shock proteins (HSPs) are a family of proteins expressed by cells in response to stressors, with changes in concentration serving as bio-indicators of oxidative stress caused by heavy metals. Exposure to cadmium ion (Cd2+) can increase the expression of HSP70 and HSP27, with the HSP70 family being more sensitive to Cd intoxication than other HSPs.
Heat shock proteins (HSPs) are a family of proteins that are expressed by cells in reply to stressors. The changes in concentration of HSPs could be utilized as a bio-indicator of oxidative stress caused by heavy metal. Exposure to the different heavy metals may induce or reduce the expression of different HSPs. The exposure to cadmium ion (Cd2+) could increase HSP70 and HSP27 over 2- to 10-fold or even more. The in vitro and in vivo models indicate that the HSP70 family is more sensitive to Cd intoxication than other HSPs. The analyses of other HSPs along with HSP70, especially HSP27, could also be useful to obtain more accurate results. In this regard, this review focuses on examining the literature to bold the futuristic uses of HSPs as bio-indicators in the initial assessment of Cd exposure risks in defined environments.
