Here, we confirmed the association of SLURP-1 antiproliferative effect in epidermoid carcinoma A431 cells with α7-nAChR (Figures 1A–C) and showed its dependence on mitogenic signaling pathways, Src family kinases and STAT transcription factors (Figures 1D, 2). Here, SLURP1 is linked to squamous cell carcinoma.
