Article Title: A FAK Inhibitor Boosts Anti-PD1 Immunotherapy in a Hepatocellular Carcinoma Mouse Model
doi: 10.3389/fphar.2021.820446
Figure Lengend Snippet: Combination of FAK inhibition and anti-PD1 therapy effectively inhibited the growth of HCC in mice (A) After 4 weeks of plasmid injection in C57BL/6 J mice, a primary hepatocellular carcinoma model was established and the mice were randomly divided into four groups (Placebo group, n = 7; Anti-PD1 group, n = 7; FAK inhibitor group, n = 7; Combination group, n = 8), and specific information about the administration (time, dosage, and method). (B) The mouse liver after 2 weeks of medication. (C–D) The liver weight of mice and the liver weight/body weight of mice were compared in each group (Placebo group, n = 7; Anti-PD1 group, n = 7; FAK inhibitor group, n = 7; Combination group, n = 8). Significance identification: ns, p ≥ 0.05; *, p < 0.05; **, p < 0.01; ***, p < 0.001. (E) HCC tissues of mice were histologically analyzed by H and E staining (scale bars, 400 μm).
Article Snippet: 2) anti-PD1 group: 200 μg PD1 antibody (anti-mPD1 clone RMP1-14, BioXcell, Cat. # BE0146) was injected by intraperitoneal injection, once every 3 days; 3) FAK inhibitor (VS4718) group: 50 mg/kg FAK inhibitor (VS4718) (Csnpharm, Cat. # CSN16593) dissolved in 0.5% methylcellulose (v/v, saline) was given to mice by gavage, twice a day.
