High impact information on NC-311

• Both genetic and pharmacologic inhibition of Ctsb in the BDL mouse reduced (a). hepatic inflammation, as assessed by transcripts for CXC chemokines and neutrophil infiltration, and (b). fibrogenesis, as assessed by transcripts for stellate cell activation and sirius red staining for hepatic collagen deposition [6].

• A loss of inotropic reserve, uncovered during beta-adrenergic stimulation, and the presence of cardiac fibrosis, shown by increased Sirius red staining of collagen, were evident in the wild-type diabetic mice but not in the MT-overexpressing transgenic diabetic mice [9].
• Moreover, early and postponed troglitazone treatments were equally effective in diminishing intrapancreatic fibrosis as quantified by Sirius red staining, hydroxyproline content, and laminin staining as well as the increased number of pancreatic stellate cells and pancreas levels of transforming growth factor-beta [10].

Chemical compound and disease context of NC-311

• Collagen content was measured in 38 needle liver biopsies (8 steatosis, 8 chronic hepatitis, 7 fibrosis and 15 cirrhosis) by a new colorimetric method based on the selective capacity of Sirius red and Fast green to bind to collagen and noncollagenous proteins, respectively [11].

• By means of staining with Sirius Red F3BA in a saturated picric acid solution, the collagen contents of rat livers with varying degrees of fibrosis have been measured quantitatively in fixed and sectioned material, using both histophotometry in situ and extraction of bound dye with colorimetric analysis [15].

Biological context of NC-311

• Collagen alpha1(I) gene expression was evaluated by in situ hybridization, total collagen was estimated by Sirius red staining, and collagen type III was detected by immunohistochemistry [16].
• Phosphorylation of MAPK p38 was analysed by western blot, and the total cardiac collagen content was analysed by Sirius red staining [17].
• Cell proliferation and collagen production were evaluated by the colorimetric methylthiazol tetrazolium assay and sirius red assay, respectively [18].
• Histology was performed using Sirius red as a specific stain for collagenous material, and computer-assisted morphometric analyses were carried out [19].
• The density of peritubular capillaries was measured with platelet-endothelial cell adhesion molecule-1 immunostaining, proliferating nuclei were detected by proliferating-cell nuclear antigen staining, apoptosis by the transferase-mediated dUTP nick end-labeling technique, macrophages by ED-1 immunostaining, and collagen by Sirius red staining [20].

Anatomical context of NC-311

• Furthermore, alpha smooth muscle actin immunohistochemistry and Sirius red staining showed an increase in the degree of fibrosis in CAR(+/+) mice fed the MCD diet at 16 weeks [21].
• We measured collagen density on Sirius red-stained serial sections of the left ventricle (LV) with a photomicroscope equipped with specific software and assessed the gene expression of procollagen alpha1(I), atrial natriuretic peptide (ANP), transforming growth factor-beta 1 (TGFbeta1), endothelin converting enzyme, and ET(B) receptor [22].
• Fibrosis was assessed by computer-assisted morphometry in the interstitial space, around coronary arteries, in microscar areas, and on left ventricular sections stained with Sirius red and by biochemical techniques [23].
• The amount of collagen and elastic fibers in the parenchymal strip was assessed semiquantitatively by point-counting in 5-micrometer-thick sections stained with either Sirius Red or Weigert's Resorcin-fuchsin. alpha-Smooth-muscle-specific actin was detected immunohistochemically [24].
• MAIN OUTCOME MEASURES: The total collagen content within the tunica media was detected (Sirius red staining and image analysis), and collagen subtypes were evaluated using polarized light microscopy; under this condition thicker type I collagen fibers appear orange or red, whereas thinner type III collagen fibers are yellow or green [25].

Associations of NC-311 with other chemical compounds

• No difference in degree of interstitial Sirius red-stained area in serial biopsies from area under concentration-over-time curves-guided cyclosporine versus tacrolimus-treated renal transplant recipients at one year [26].
• The collagen content was estimated by morphometry on left ventricle sections stained with Sirius red, and by biochemical quantification of the hydroxyproline concentration [27].
• Histopathology using hematoxylin-eosin, periodic-acid Schiff and Sirius-red staining, immunohistochemistry for macrophages, myofibroblasts, transforming growth factor-beta (TGF-beta)1 and P2X7, and immunofluorescence for apoptotic cells (terminal deoxynucleotidyltransferase-mediated deoxyuridine triphosphate nick-end labeling) were performed [28].

Gene context of NC-311

• Rats receiving control virus developed considerably more fibrotic lesions identified by Sirius Red staining and collagen I immunostaining compared to Sham rats, and eNOS gene delivery significantly reduced collagen accumulation. eNOS gene transfer also reduced TUNEL-positive apoptotic cells [31].

• The extent of interstitial collagen deposition measured with Sirius red and the accumulation of alpha-smooth muscle actin and TGF-beta protein after 6 and 12 mo were similar for both immunosuppressive regimens. mRNA levels of TGF-beta and collagens alpha1(I) and alpha1(III) were not significantly different in the treatment groups either [33].
• Sirius red staining showed that kallikrein gene transfer reduced renal fibrosis, which was confirmed by decreased collagen I and fibronectin levels [34].
• Collagen was stained with Sirius red, and mediators of inflammation were identified by immunolabeling (vascular cell adhesion molecule, nuclear factor-kappaB, infiltrating ED-1-positive macrophages and monocyte chemotactic protein-1) or by western blot (platelet-endothelial cell adhesion molecule-1) [35].
