1 The effect of arsenite exposure on cell viability, protein synthesis, energy metabolism and the expression of genes coding for cytoplasmic (hsp70) and endoplasmic reticulum (ER; gadd153, grp78, grp94) stress proteins was investigated in primary neuronal cell cultures. arsenite heat shock protein family A (Hsp70) member 4 Homo sapiens
2 Arsenite induced a transient inhibition of energy metabolism after 1 h of exposure, but energy state recovered completely after 3 h. Arsenite exposure affected the expression and translation of genes coding for HSP70 and GRP78, GRP94, GADD153 to different extents. arsenite heat shock protein family A (Hsp70) member 4 Homo sapiens
