Figure 4From: A comparative study of lung toxicity in rats induced by three types of nanomaterialsReal-time PCR (A) and Western blot (B) analysis of selected genes: SM22α, Transgelin 2. Bars represent the relative fold changes compared with controls. Error bars represent the S.E.M. for the average fold changes. Statistical significance (p < 0.05) between expression following nanomaterial exposure and the controls is denoted by an asterisk (*).Back to article page
