HEK293, a human embryonic kidney cell line, was acquired by American Culture Collection (Manacas, Virginia, USA). The cells kept the medium phase (culture medium) of Beko's improved Eagle, which was soft and had 1% fetal bovine serum (fetal bovine serum, fetal bovine serum, Logan, UT Starcom, USA) mented. Recombinant human epidermal growth factor, U126, SB2358 and SP6125 were purchased from Calbiochem (San Diego, California, USA). Antibodies to exhaust gas recirculation-1 and GAPDH are based on the biological Santa Cruz (Santa Cruz, CA, USA). Firefly and Haishen Shuanghui brand (trademark) luciferase detection system was purchased from the kit (Madison, Wisconsin, USA). ）。 HEK293, a human embryonic kidney cell line, was acquired by American Culture Collection Center (Manacas, Virginia, USA).
