Identification of Candidate Genes in Breast Cancer Induced by Estrogen Plus Progestogens Using Bioinformatic Analysis. (PubMed, Int J Mol Sci)
Importantly, CNNE2 protein level could be upregulated with EPT and attenuated by estrogen receptor antagonist, acolbifene and had interactions with cancer driver genes (AKT1 and KRAS) and high mutation frequency gene (TP53 and PTEN) in breast cancer patients. In conclusion, the current study showed that CCNE2, CDCA5, RAD51, TCF19, KNTC1, MCM10, and NEIL3 might contribute to EPT-related tumorigenesis in breast cancer, with CCNE2 might be a sensitive risk indicator of breast cancer risk in women using MHT.

AGR2 , an estrogen response gene associated with tamoxifen resistance, is modulated by acolbifene in premenopausal women at high risk for development of breast cancer (SABCS 2021)
ERGI and AGR2 change indicate favorable modulation by acolbifene and appear to provide independent information. Conclusions These results suggest that change in expression of benign breast AGR2 might be a useful addition to change in expression of other classic estrogen response genes in evaluating the potential of novel SERMs such as acolbifene compared to standard SERMs like tamoxifen in early phase prevention trials.
