Figure Lengend Snippet: Detection of Tyr-397 phosphorylated FAK and total FAK levels in Beta-TC-3 cells following treatment with FAKi. Upper panels: Beta-TC-3 cells were treated with 10 µM or 30 µM of the indicated FAKi (VS-4718, Ifebemtinib, VS-6062, GSK2256098, CEP-37440, or Defactinib) or with DMSO (0.1% or 0.3%) as a vehicle control. After 24 h, protein lysates were analyzed by Western blotting for Tyr-397 phosphorylated FAK (Tyr397-p125FAK) and total FAK (p125FAK). β-actin was used as an internal loading control. Arrows indicate bands corresponding to the expected molecular weight of 125 kDa. Lower panels: Quantification of the indicated protein levels was performed by densitometric analysis using ImageJ version 1.53a software. Expression levels of phosphorylated Tyr-397 FAK and total FAK were normalized to β-actin and are shown relative to DMSO-treated control cells, which were set to 100%. Shown are mean values ± SD from 2 samples. Notable both phosphorylated and total FAK proteins were not only detected at the expected molecular weight of 125 kDa but also at higher and lower molecular weights, suggesting the presence of multiple FAK isoforms in Beta-TC-3 cells [ , ].

Figure Lengend Snippet: Cytotoxic activity of FAKi with dose–response curves in pancreatic tumor cells. The five pancreatic tumor cell lines MIA Paca-2, BxPC-3, Capan-1, AsPC-1, and Beta-TC-3 were incubated with FAKi VS-4718, Ifebemtinib, VS-6062, GSK2256098, CEP-37440, or Defactinib at concentrations of 0.1–500 µM. Cell viability was determined by XTT assay 72 h post-treatment. Data were set relative to DMSO-treated cells. Shown are the nonlinear fits of each FAKi with mean values ± SD from 3 independent experiments.

Figure Lengend Snippet: Influence of FAKi on the replication and cytotoxicity of PD-H. ( A ) Viral growth curves. MIA Paca-2 and Capan-1 cells were infected with 3 and 0.1 MOI of PD-H for 1 h and thereafter incubated with medium containing the FAKi VS-4718, VS-6062, CEP-37440, or Defactinib at indicated concentrations, or DMSO, or cell culture medium alone for 24 h. Virus titers were determined by plaque assay on HeLa cells. Shown are mean values ± SD from 3 independent experiments. Statistical significance compared to PD-H + DMSO, * p < 0.05, ** p < 0.01, and *** p < 0.001; n.s., not significant. ( B ) Cell viability of the PD-H/FAKi approach described under ( A ). Cell viability was determined by XTT assay 24 h post-treatment. Data were set relative to DMSO-treated cells. Statistical significance compared to non-treated cells, * p < 0.05 and *** p < 0.001; n.s., not significant.
