Figure Lengend Snippet: Characteristics of paclitaxel-resistant cells. ( a , b ) Cells were seeded in triplicates in 96-well plates in 0.1 mL culture medium at a density of 1 × 10 4 cells/well. After 24 h, the cells were treated with paclitaxel. MTT assay performed 48 h after treatment showed that the paclitaxel-resistant cells (TOV-21G/PTX and OV-90/PTX) had higher IC 50 than the parental cells. ( c , d ) Paclitaxel treatment reduced the viability of parental cells, while the paclitaxel-resistant cells continued to grow. ( e ) Western blot analysis revealed that DKK3 was lost and that β-catenin and P-glycoprotein were upregulated in paclitaxel-resistant cells (Res) compared to that in their parent cells (Con). β-Actin was used as the loading control. * p < 0.01.

Figure Lengend Snippet: DKK3 cleavage utilization as PD biomarker in the phase 1 study following treatment with anti-HtrA1 Fab15H6.v4.D221. The SAD stage consisted of doses of anti-HtrA1 Fab15H6.v4.D221 ranging from 1 to 20 mg ( n = 15). Levels of cleaved DKK3 were assessed by Western blot in aqueous humor of patients at baseline and at multiple time points following anti-HtrA1 treatment as a biomarker of anti-HtrA1 modulation of HtrA1 protease activity. A plot of percent change from baseline for aqueous humor cleaved DKK3 by study day is shown for each treatment group.
