Figure Lengend Snippet: m2AChR signalling in dental pulp stem cells is mediated by the MAPK/ERK signalling pathway. A Analysis of expression of genes involved in the MAPK/ERK signalling pathway following stimulation of DPSCs with the M2 agonist (100 µM APE) for 72 h. (i) ERK1 ( MAPK3 ), (ii) ERK2 ( MAPK1 ) and (iii) Proliferating cell nuclear antigen ( PCNA ), Cells cultured in media alone acted as a control (ctrl). M2 agonist = cells cultured in media containing 100 µM APE. Statistical analysis was performed using unpaired two-tailed t-tests. B Time course of phosphorylation of ERK 1/2 after activation of the dental pulp stem cell m2AChR determined using an in-cell ELISA. Cells cultured in media alone acted as a control (ctrl). M2 agonist = cells cultured in media containing 100 µM APE. Statistical analysis was performed using one-way ANOVA with Dunnett’s multiple comparisons test. Data are presented as mean ± SEM from duplicate wells across three independent experiments. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001
Article Snippet: To evaluate the activation of the extracellular signal-regulated kinases (ERK) 1 & 2, a Phospho-ERK1 (T202/Y204) / ERK2 (T185/Y187) incell ELISA (R&D Systems, UK) was performed.
