TAM might bind and activate ERα36—a variant of ERα in BC stem cells that is associated with poor prognoses—in order to enhance the stemness and metastasis of BC cells via the transcriptional stimulation of the protein-coding gene Aldehyde Dehydrogenase 1 Family Member A1 (ALDH1A1) [98]. Here, ALDH1A1 is linked to breast cancer.
