The photocytotoxicity of the photosensitisers and conjugates was assayed by the MTT assay using the SKOv3-CEA-1B9 cell line (35A7 and FSP 77) and the Colo 320 cell line (17.1A).
In the latter, the epithelial cells undergo morphological changes to acquire fibroblast or myofibroblast markers such as fibroblast-specific protein 1 (FSP-1), α-smooth muscle actin, N-cadherin, and vimentin, while losing epithelial markers such as E-cadherin, occludin, and desmoplakin.
Immunofluorescence staining was performed to detect the co-expression of endothelial markers, such as CD31, and fibroblast markers, such as fibroblast-specific protein 1 (FSP-1).
Primary antibodies used were alpha sarcomeric actinin (αSA, ab9465, Abcam, UK), fibroblast specific protein 1 (FSP-1, PAK0073, Linaris, Germany), alpha smooth muscle actin (αSMA, 6198, Sigma, Germany), or a non-immune immunoglobulin.
Fibroblast-specific protein 1 (FSP-1; also known as S100A4 and MTS-1), an S100 class of cytoskeletal protein, α-SMA, and collagen I have provided reliable markers to characterize the mesenchymal products generated by the EMTs that occur during the development of fibrosis in various organs [ 21].
377 frameshift antigens were represented in 830 FSP peptides on the array.
Microstructural examinations showed that the GNP distribution was significantly improved as the number of FSP passes increased, with a uniform dispersion of GNPs achieved after 2 FSP passes.
The working sample is of 756 FSP with monthly data covering a period of 44 months, from October/2005 to June/2009 (1 month was missing in FLOSSmole, July 2008).
The previously developed photosensitisers were conjugated to MAb 35A7, FSP 77 and 17.1A.
Given with AlCl3, FSP decreased plasma glucose to the normal value.
