A combination of neurotensin and insulin potently decreases YAP phosphorylation at Ser127 and Ser397 in PDAC cells. A combination of neurotensin and insulin potently decreases YAP phosphorylation at Ser127 and Ser397 in PDAC cells. Confluent PANC-1 cells (A and B) or MiaPaca-2 cells (C and D) were stimulated either without (−) or with 5 nmol/L neurotensin (NT), 10 ng/mL insulin (Ins), or their combination (NT + Ins) for 30 or 60 minutes, as indicated. Cultures were then lysed with 2× SDS-PAGE sample buffer and analyzed by immunoblotting with antibodies that detect YAP phosphorylated at Ser127 and Ser397. Immunoblotting for total YAP and GADPH were also included. B and D, Quantification of total YAP phosphorylated at Ser127 and Ser397 was performed using Multi Gauge V3.0. The results represent the mean ± SE; n = 4 (independent experiments) and are expressed as percentage of the maximal level of YAP phosphorylated at Ser127 and Ser397. NT + Ins significantly decreased YAP phosphorylation at Ser127 and Ser397 as compared with untreated controls: **, P < 0.01; *, P < 0.05 (one-way ANOVA with Bonferroni t test). Fang Hao et al.
