NE regulated the EMT and MMP expression levels via β2-AR in SACC cells.

Notes: (A, B) qRT-PCR analysis of the expression of indicated genes in SACC-83 and SACC-LM cells treated with 10 μM NE and/or 10 μM ICI118,551. GAPDH expression was detected as an internal control. The mRNA expression levels of E-cadherin, N-cadherin, Vimentin, Slug, MMP2, and MMP9 were quantified and expressed as fold-changes compared to the control groups. (C, D) Western blot analysis of the expression of the indicated proteins in SACC-83 and SACC-LM cells treated with 10 μM NE and/or 10 μM ICI118,551. GAPDH expression was detected as an internal control. (E, F) Protein expression levels in SACC-83 and SACC-LM cells were quantified and expressed as fold-changes compared with control groups. *P<0.05, **P<0.01, ***P<0.001. The error bars indicate the SD.
