HSF1 and B-cell chronic lymphocytic leukemia: The analysis of HSF1 and HSP70 expression levels showed that HSF1 decreased from 1.15 ± 0.69 to 0.50 ± 0.64 and HSP70 from 1.13 ± 0.69 to 0.54 ± 0.35, in CLL cells cultured alone and with 40 μM RSV, respectively (p < 0.01, paired Student’s t test—Figure 1C).
