Title

Down-regulation of HSP40 gene family following OCT4B1 suppression in human tumor cell lines

Pages

  187-193

Abstract

 Objective(s): The OCT4B1, as one of OCT4 variants, is expressed in cancer cell lines and tissues more than other variants and plays an important role in apoptosis and stress (heat shock protein) pathways. The present study was designed to determine the effects of OCT4B1 silencing on expressional profile of HSP40 gene family expression in three different human Tumor cell lines. Materials and Methods: The OCT4B1 expression was suppressed by specific siRNA transfection in AGS (gastric adenocarcinoma), 5637 (bladder tumor) and U-87MG (brain tumor) cell lines employing Lipofectamine reagent. Real-time PCR array technique was employed for RNA qualification. The fold changes were calculated using RT2 Profiler PCR array data analysis software version 3. 5. Results: Our results indicated that fifteen genes (from 36 studied genes) were down-regulated and two genes (DNAJC11 and DNAJC5B) were up-regulated in all three studied Tumor cell lines by approximately more than two folds. The result of other studied genes (19 genes) showed different expressional pattern (up or down-expression) based on Tumor cell lines. Conclusion: According to the findings of the present study, we may suggest that there is a direct correlation between OCT4B1 expression in Tumor cell lines (and tissues) and HSP40 family gene expressions to escape from apoptosis and cancer expansion.
