In vivo acquired resistance to tamoxifen is associated with irreversible loss of IGF1R, upregulation of insulin receptor and enhanced sensitivity to insulin

Katelyn J. Hoff, Priya Periakaruppan, Courtney Baar, Valeria C. Torres Irizarry, Deepali Sachdev

This study shows that in vivo tamoxifen resistance in HR+ breast cancer is linked to IGF1R loss, IR-A upregulation, and increased insulin sensitivity, suggesting potential therapeutic strategies targeting IR-A.
