( D , E ) Proliferation curves of T24 and 5637 cells treated with DMSO or DHE (20, 40 μM) over 5 consecutive days. ( F , G ) Representative images and statistical quantification of colony formation assays for T24 ( F ) and 5637 ( G ) cells following DHE treatment. ( H ) Wound healing assays evaluating the migratory ability of T24 and 5637 cells treated with increasing concentrations of DHE (0, 10, 20, 40 μM).

Figure Lengend Snippet: Synthesis and biological validation of a DHE-derived photoaffinity probe. ( A ) Schematic representation of the ABPP (Activity-Based Protein Profiling) workflow. The process includes cell lysis, probe incubation, UV-induced cross-linking, click chemistry-mediated biotinylation, and streptavidin-based enrichment followed by LC-MS/MS or SDS-PAGE analysis. ( B ) Synthetic route of the DHE-Probe. Reaction conditions: (a) diazirine–alkyne linker, (b) K 2 CO 3 , DMF, 65 °C, 16 h. The final probe includes a photo-cross-linker and an alkyne handle for target capturing. ( C , D ) Comparison of the anti-proliferative effects of DMSO, DHE, and DHE-Probe (40 μM) in T24 ( C ) and 5637 ( D ) bladder cancer cells. Cell viability was measured 24 h post-treatment.

Figure Lengend Snippet: Invasion of E. coli strains from three phylogenetic groups in HTB-9 and CRL2169. Group AD refers to strains from either phylogenetic group A or D. IBC (intracellular bacterial community) refers to intracellular bacteria recovered. (A) Invasion into HTB-9: colonies recovered. (B) Invasion into HTB-9: cumulative comparison of group B2 vs non-B2 strains. This panel replots all the technical replicates for each strain from panel A. (C) Invasion into CRL2169: colonies recovered. (D) Invasion into CRL2169: cumulative comparison of group B2 vs non-B2 strains. This panel replots all the technical replicates for each strain from panel C. (E) Ratio of invasion into HTB-9 to CRL2169: individual strains. (E) Ratio of invasion into HTB-9 to CRL2169: cumulative comparison.

Figure Lengend Snippet: Comparison of wild-type UTI89 and mutants in the pili major structural subunit, fimA , the flagellar major subunit, fliC , and a double mutant in both fimA and fliC . Statistical significance was determined by Kruskal-Wallis non-parametric test of multiple comparisons. (A) Invasion into CRL2169. For parental, Δ fimA , Δ fliC , and Δ fimA Δ fliC strains, the samples sizes were 5, 3, 6, and 6, respectively. For the double mutant, three replicates had no recoverable bacteria. (B) Invasion into HTB-9. For parental UTI89 and Δ fimA , Δ fliC , and Δ fimA Δ fliC derivatives, the samples sizes were 6, 3, 6, and 6, respectively. For the double mutant, none of the six replicates had recoverable bacteria. (C) Mouse model of urinary tract infection. For parental, Δ fimA , Δ fliC , and Δ fimA Δ fliC strains, the samples sizes were 23, 8, 12, and 8, respectively. For the double mutant, none of the 8 replicates had recoverable bacteria.
