FGF1 treatment increases the basal ECAR in breast cancer cell lines (Castillo-Castrejon et al., 2023), while FGF2 treatment increases lactate production in murine adipocytes (Kihira et al., 2011), rat Sertoli cells (Riera et al., 2002), and human squamous cell carcinoma cells (Fumarola et al., 2017). The gene discussed is FGF1; the disease is breast cancer.
