Figure 5From: Cancer-associated fibroblasts from human NSCLC survive ablative doses of radiation but their invasive capacity is reducedSecretion of matrix metalloproteases and endogenous inhibitors by CAFs. In panel (A), average determinations of the MMPs levels found in culture supernatants 4 to 6 days post-irradiation from 5 donors is represented (donors #1, #5, #7, #11, #14 in Table 1). Only MMPs that showed values above the detection limit of the assay are shown. Pale grey bars non-irradiated cultures; dark grey bars cells receiving (1 × 18 Gy). Statistically significant differences between control and irradiated cultures were observed for MMP-3 (p < 0.05), and in four out of five donors for MMP-1 (p = 0.06 all donors; p < 0.05 excluding donor-1). In panel (B), expression patterns of TIMP-1, -2, -3 from the same supernatants used in (A) are shown.Back to article page
