Figure Lengend Snippet: Representative images showing collagen XXIII staining in the NSCLC subtypes: A) lung adenocarcinoma, B) large cell carcinoma, and C) squamous cell carcinoma. D) Collagen XXIII staining is absent in small cell lung cancer tissues. Staining was performed using the 468642 antibody and images were acquired using a 20X objective lens.

Figure Lengend Snippet: A) Bar graph showing percentage of patient tumor or normal tissue cores expressing collagen XXIII across all NSCLC TMAs and each individual TMA. Single asterisks indicate unavailable data. Patients lacking detectable collagen XXIII staining in all of their representative tissue cores were considered negative for collagen XXIII protein expression (Supplementary Table 1). Chi-squared analysis of a 3 by 2 contingency table for the combined TMA data was highly significant (p<0.001). A two-tailed p-value was calculated for each comparison between NSCLC subtype and normal lung tissue using Fisher’s Exact Test. Highly significant differences (p<0.001) are indicated (***). For immunohistochemical analysis, the 468642 antibody was used on the US Biomax and M.D. Anderson Cancer Center TMAs, while the 6.1B antibody was used on the Brigham and Women’s Hospital TMA. B) ROC curve plotting the true positive rate against the false positive rate for the different possible collagen XXIII staining intensity thresholds. (Tabulated data in supplementary table 2) Area under the curve = 0.860. C) Representative Kaplan Meier curves demonstrating reduced recurrence-free survival in patients with high (>85) collagen XXIII staining intensity (p= 0.013). Data for all examined threshold values is included in supplementary table 4.

Figure Lengend Snippet: A) Collagen XXIII is detected in urine from 23 of 29 (79%) NSCLC patients but only in 15 of 54 (28%) control urine samples (Fisher’s Exact test; p<0.0001 ***). B) Representative Western blot demonstrating collagen XXIII positivity in a subset of urine samples using the 468642 antibody. Recombinant collagen XXIII corresponding to the cleaved ectodomain was used as a positive control (+ con) and is the predominant form of urinary collagen XXIII. Arrow indicates potential non-reduced protein complexes.

Article Title: The Methoxyflavonoid Isosakuranetin Suppresses UV-B-Induced Matrix Metalloproteinase-1 Expression and Collagen Degradation Relevant for Skin Photoaging

doi: 10.3390/ijms17091449

Figure Lengend Snippet: Effect of isosakuranetin on the level of type-1 procollagen in UV-B-irradiated NHDF cells. After pretreatment of fibroblast cells with different concentrations of isosakuranetin for 24 h, cells were irradiated with UV-B (20 mJ/cm 2 ), and then cells were further incubated for 24 h. Total collagen levels were measured in the culture media of control cells or UV-B-treated cells by SirCol assay. Data shown are mean values ± S.D. * p < 0.05 vs. non-UV-B-irradiated cells, ** p < 0.05 vs. UV-B-irradiated cells.
