Figure Lengend Snippet: Proteomics analysis of differential protein expression. A: Principal component analysis (PCA) of normalized protein counts PCA of protein expression across normal, carbon tetrachloride (CCl₄) and PF562271 (PF) conditions. The first principal component (PC1) explains 39.3% of variance, while PC2 explains 9.5%. The three conditions show clear separation; B: Volcano plot showing differentially expressed proteins between the normal and CCl₄ groups. Significant proteins ( P < 0.05, log2 fold change > 1 or < -1) are highlighted; C: Volcano plot comparing the CCl₄ and PF groups. Significant proteins are marked, indicating differential expression between these two conditions ( P < 0.05); D: Mfuzz clustering of protein expression profiles. Clusters 1, 3, and 4 are shown, highlighting distinct expression trends in normal, CCl₄, and PF conditions; E: UpSet plot showing overlaps of differentially expressed proteins between comparisons (normal vs CCl₄, CCl₄ vs PF) and clusters from Mfuzz analysis; F: Venn diagram showing overlap of differentially expressed proteins between the normal vs CCl₄ and CCl₄ vs PF groups. The diagram indicates unique and shared proteins across the conditions.
Article Snippet: LX-2 cells, an activated human HSCs line[ ], were treated with varying concentrations of the FAK inhibitor PF562271 (2.5 μM, 5 μM, 10 μM) based on the IC 50 provided by MCE (MedChem Express).
