TGFB1 and breast cancer: While TGF-β1 decreases basal OCR in mink lung epithelial cells (Yoon et al., 2005), breast cancer cells (Lee et al., 2016), and activated human effector memory CD4+ T cells (Dimeloe et al., 2019), it increases basal and maximal OCR in mouse podocytes (Abe et al., 2013) and human fibroblasts (Selvarajah et al., 2019).
