![A ChIP peak locations within the human EIF4EBP1 promoter, exon 1 and part of intron 1 (hg38; Chr8: 38,030,342 - 38,031,906) from ChIP-sequencing data for MYC (Encode consortium, Encyclopedia of DNA Elements at UCSC [ , ]) and an illustration of the <t>luciferase</t> reporter construct containing the EIF4EBP1 promoter, exon 1 and part of intron 1 (−192; +1372) coupled to Firefly luciferase, with the indicated binding sites of the transcription factor MYC. The three E boxes present in the promoter, and corresponding introduced mutations, are indicated. B , C HEK293-T cells were transfected with the (−192; +1372) EIF4EBP1 promoter reporter construct, together with 25 ng, 50 ng and 100 ng MYC ( B ) or the (−192; +1372) EIF4EBP1 promoter reporter constructs containing a mutation of each of the E boxes (as indicated in A ), together with 25 ng MYC ( C ). For ( B ) and ( C ), a <t>Renilla</t> Luciferase vector was used as an internal control and luciferase activities were detected using the Dual-Luciferase Reporter Assay. Firefly luciferase activity was normalized to Renilla luciferase activity and the ratio was normalized to the corresponding 0 ng ( B ) or control ( C ) condition. Data represent the mean of four ( B ) or three ( C ) independent replicates ± standard deviation (SD). Significance was calculated using an unpaired and two-tailed parametric t test (* p < 0.05, **** p < 0.0001). A representative immunoblot analyzing expression of MYC is presented in ( B ). D , E Med8A ( D ) and HD-MB03 ( E ) MB cells were transiently transfected with negative control siRNAs (siCtrl), or two different siRNAs each targeting MYC (siMYC#1 and siMYC#2). Cells were re-transfected after 96 h with their corresponding siRNA and incubated for a total of 168 h. MRNA was harvested to determine the expression levels of EIF4EBP1 and MYC by qRT-PCR. Data obtained by qRT-PCR represent the mean of three independent replicates ± SD and the fold change in expression was normalized to the negative control (siCtrl). Significance was calculated using an unpaired and two-tailed parametric t test (* p < 0.05, ** p < 0.01, **** p < 0.0001). F Med8A MB cells were transiently transfected with negative control (siCtrl) or a pool of four different siRNAs (see Table ) targeting MYC (siMYC). Cells were incubated 72 h and protein was harvested for immunoblotting using the indicated antibodies. G , H Control and MYC overexpressing (MYC OE) ONS76 ( G ) or UW228.3 ( H ) cells were lysed. Levels of EIF4EBP1 mRNA were determined by qRT-PCR. Levels of 4EBP1 and MYC proteins were determined by immunoblots using the indicated antibodies. Data obtained by qRT-PCR represent the mean of three independent replicates ± SD and the fold change in expression was normalized to the control. Significance was calculated using an unpaired and two-tailed parametric t test (*** p < 0.001, **** p < 0.0001).](https://pub-med-central-images-cdn.bioz.com/pub_med_central_ids_ending_with_7489/pmc12267489/pmc12267489__41420_2025_2601_Fig4_HTML.jpg)
