- Fig. 4 Generation and evaluation of tumor metastasis in Scgb1a1-Cre/PCSK9 fl/fl mice. (A) Strategy of generating lung epithelium-specific PCSK9 conditional KO mice. Lung epithelial cell-specific Scgb1a1 promoter-driven inducible Cre recombinase-estrogen receptor fusion protein (CreER) transgenic mouse (Scgb1a1-CreER) was crossed with Pcsk9 fl/fl mice . For PCSK9 depletion, Scgb1a1 CreER / PCSK9 fl/fl mice were intraperitoneal injected with tamoxifen (75 mg/kg) once a day for five times. (B) Lysates of lung bronchial tissues from Scgb1a1-Cre mice (control) and Scgb1a1-Cre/PCSK9 fl/fl mice were subjected into immunoblot analysis with an antibody to PCSK9. (C) Immunochemistry with antibody to PCSK9 in lung bronchial tissues from Scgb1a1-Cre and Scgb1a1-Cre/PCSK9 fl/fl mice. (D) B16F10 melanoma cells were inoculated into 8-wk-old male Scgb1a1-Cre and Scgb1a1-Cre/PCSK9 fl/fl mice via tail vein injection. The mice were sacrificed after fourteen days. The representative photograph is the dorsal side of a lung with metastatic lesions. (E) The number of metastatic colonies was counted and statistically analyzed with the Mann-Whitney U test. Fig 4

- Figure 5 PCSK9 expression negatively correlates with IL36B and IL36G expression in keratinocytes and skin. ( A ) In cultured keratinocyte cell lines, PCSK9 expression negatively correlated with IL36B and IL36G expression. PCSK9 expression did not correlate with PGK1 expression, a housekeeping gene. In these plots, each dot represents an in vitro cultured keratinocyte cell line under a different culture condition (control, IL-4, IL-13, IL-17A, IFN-alpha, IFN-gamma, TNF-alpha, IL-4 and IL-13, IL-17A and IFN-gamma, IL-17A, and TNF-alpha). Normalized log 2 transformed reads for each gene are plotted on the x axis and y axis. Pearson's correlation coefficients and P values are displayed on each plot. ( B ) Epidermal expression of PCSK9 and IL36G . Representative pictures of an IHC staining for PCSK9 and IL36G as well as the matching isotype controls in lesional skin of a patient with psoriasis (upper row) and healthy control nonlesional skin (lower row). The single arrow points to the basal layer. Double arrows point to the granular layer. Scale bar: 100 mum.
