OJeanJean_eRF3a_ATF4


ABSTRACT: We previously showed that eRF3a depletion in the human colon carcinoma cell line HCT116 p53+/+ induces mTOR signaling pathway inhibition (Chauvin et al., 2007) suggesting that eRF3a belongs to a regulatory mechanism that modulate mTOR activity. However, this mechanism and the precise role of eRF3a remain to be determined. Here, to elucidate the mechanism dictating mTOR signaling pathway inhibition, we aimed to define the transcript expression and polysome profiles of HCT116 cells after short interfering RNA (siRNA)-mediated depletion of eRF3a. Three days after HCT116 cells electroporation with either sh-3a1 which was previously shown for effectively silence eRF3a (Chauvin et al., 2005) or control shRNA (sh-Ctrl), total and polysome-associated RNAs were extracted and we conducted a microarray analysis of differentially expressed genes using the Illumina HumanHT-12 Expression BeadChips.
