Real time RT/PCR expression of cassini in response to cellular stress. 8093 ALL cells were treated, as indicated in Methods, with (A) hypertonic medium (n = 1); (B) hypotonic medium (n = 3); (C) radiation (n = 2); (D) heat shock (n = 3); and (E) H2O2 (n = 3). Values are represented as mean ± SD of duplicate real-time RT/PCR. D **p < 0.01 heat shock versus control. Other comparisons, n.s., p > 0.05.
