Evaluation of galectin-3 expression in ameloblastoma stromal fibroblasts and its association with recurrence
Introduction: Ameloblastoma is a benign odontogenic neoplasm with a high risk of recurrence. Ameloblastoma stromal fibroblasts are associated with tumor growth and invasion; however, a few studies have evaluated the immunohistochemical characteristics of stromal fibroblasts and their association with recurrence in Ameloblastoma. Galectin-3 (gal-3) is a member of the B-galactoside bonding protei...
متن کاملModulation of TGF-beta signaling by proinflammatory cytokines in articular chondrocytes.
OBJECTIVE The normal structure and function of articular cartilage are the result of a precisely balanced interaction between anabolic and catabolic processes. The transforming growth factor-beta (TGF-beta) family of growth factors generally exerts an anabolic or repair response; in contrast, proinflammatory cytokines such as interleukin 1 beta (IL-1beta) and tumor necrosis factor-alpha (TNF-al...
متن کاملCharacterization of the human proline/arginine-rich end leucine-rich repeat protein (PRELP) gene promoter and identification of a repressor element.
The 5'-flanking region of the human proline/arginine-rich end leucine-rich repeat protein (PRELP) gene has been characterized for both promoter and repressor activity by using a variety of reporter gene constructs and transient transfection into chondrocytes or fibroblasts. The human PRELP gene lacks a TATA box, and in its absence a Sp1-binding site residing 29 bp upstream of the transcription ...
متن کاملDetection and characterization of Sp1 binding activity in human chondrocytes and its alterations during chondrocyte dedifferentiation.
We have detected DNA binding activity for a synthetic oligonucleotide containing an Sp1 consensus sequence in nuclear extracts from human chondrocytes. Changes in the levels of Sp1 oligonucleotide binding activity were examined in nuclear extracts from freshly isolated human chondrocytes, from chondrocytes that had been cultured under conditions that allowed the maintenance of a chondrocyte-spe...
متن کامل-prostaglandin J2 Inhibits Bay 11-7085-induced Sustained Extracellular Signal-regulated Kinase Phosphorylation and Apoptosis in Human Articular Chondrocytes and Synovial Fibroblasts*
We have previously shown that nuclear factorB inhibition by adenovirus expressing mutated I Bor by proteasome inhibitor increases human articular chondrocytes sensibility to apoptosis. Moreover, the nuclear factorB inhibitor BAY11-7085, a potent anti-inflammatory drug in rat adjuvant arthritis, is itself a proapoptotic agent for chondrocytes. In this work, we show that BAY 11-7085 but not the p...
