The expression of HSP70 is affected by PZ and ASA. Confluent RIE1 were incubated with 70 µM PZ for 24 h prior to ASA stimulation (15 mM) for 24 h and (A) WB and (B) densitometry were performed to assess HSP70 expression. The WB result is a representative image of three separate experiments. The value of densitometry indicates relative HSP70 expression with actin as a control. The value is the mean ± SEM of three separate WB. *p<0.005 compared with 0 h (PZ). **p<0.005 compared with 0 h (ASA). ***p<0.005 compared with 0 h (PZ + ASA).
