Fig. 6From: GDNF-RET signaling and EGR1 form a positive feedback loop that promotes tamoxifen resistance via cyclin D1CCND1 upregulation through GDNF-RET signaling. A UCSC genome browser data showing EGR1 binding motif located on the CCND1 promoter. B CCND1 mRNA levels after 1 μM TAM treatment showing increased transcription in the presence of rGDNF after 2, 3, and 12 h. C ChIP-qPCR data showing increased EGR1 binding to the CCND1 promoter. Student’s paired T-Test was used for statistical analyses. * p < 0.05, *** p < 0.0005Back to article page
