BACKGROUND As most colorectal cancers (CRC) develop from villous adenomas, studying alterations in gene expression profiles across the colorectal adenoma-dysplasia-carcinoma sequence may yield potential biomarkers of disease progression. METHODS Total RNA was extracted, amplified, and biotinylated from colonic biopsies of 15 patients with CRC, 15 with villous adenoma and 8 normal controls. Ge...
In situ hybridization is used to survey the tissue-specific and developmental expression of the cloned mouse gene Sparc, coding for a protein homologous to the bovine Ca++-binding protein, osteonectin. High levels of SPARC RNA are found in osteoblasts and odontoblasts. In addition, high grain counts are associated with a variety of other cell types in the embryo and newborn mouse, including par...
Matricellular proteins are extracellular matrix proteins that modulate cell-matrix interactions and cell function, and do not seem to have a direct structural role. The family includes tenascin-C (TN-C), tenascin-X (TN-X), osteonectin, osteopontin, thrombospondin-1 (TSP1) and thrombospondin-2 (TSP2). Expression of matricellular proteins is high during embryogenesis, but almost absent during nor...
Purpose: This study sought to compare the elemental constitution, morphological characteristics, particle size distribution, biocompatibility, and mineralization potential of Ortho MTA (OMTA) and ProRoot MTA (PMTA). Materials and Methods: OMTA and PMTA were compared using energy-dispersive spectrometry, particle size analysis, and scanning electron microscopy. The biocompatibility and mineraliz...
