Abstract
Osteoarthritis is a whole-joint disease characterized by the progressive destruction of articular cartilage involving abnormal communication between subchondral bone and cartilage. Our team previously identified 14-3-3ε protein as a subchondral bone soluble mediator altering cartilage homeostasis. The aim of this study was to investigate the involvement of CD13 (also known as aminopeptidase N, APN) in the chondrocyte response to 14-3-3ε. After identifying CD13 in chondrocytes, we knocked down CD13 with small interfering RNA (siRNA) and blocking antibodies in articular chondrocytes. 14-3-3ε-induced MMP-3 and MMP-13 was significantly reduced with CD13 knockdown, which suggests that it has a crucial role in 14-3-3ε signal transduction. Aminopeptidase N activity was identified in chondrocytes, but the activity was unchanged after stimulation with 14-3-3ε. Direct interaction between CD13 and 14-3-3ε was then demonstrated by surface plasmon resonance. Using labeled 14-3-3ε, we also found that 14-3-3ε binds to the surface of chondrocytes in a manner that is dependent on CD13. Taken together, these results suggest that 14-3-3ε might directly bind to CD13, which transmits its signal in chondrocytes to induce a catabolic phenotype similar to that observed in osteoarthritis. The 14-3-3ε-CD13 interaction could be a new therapeutic target in osteoarthritis.

The regulation of the inflammatory response through nuclear factor-kappab pathway by angiotensin IV extends the role of the renin angiotensin system in cardiovascular diseases.

Abstract
The renin angiotensin system (RAS) participates in the pathogenesis of cardiovascular diseases. Although angiotensin II has been considered the effector peptide of RAS, accumulating evidence shows that other RAS peptides also posses important functions, some of them involved in cardiovascular pathology. Many studies support the importance of N-terminal angiotensin degradation product, angiotensin IV (AngIV), in the fields of cognition, renal metabolism, and pathophysiologic conditions. The novel data discussed here show that AngIV could contribute to cardiovascular damage. Angiotensin IV can be generated by degradation of angiotensin II, by aminopeptidase (AP) N, or by other proteases, which could be activated during tissue damage, suggesting that elevated AngIV levels can be found in pathologic conditions. Angiotensin IV binds to a specific receptor, AT(4), which has recently been identified as an insulin-regulated AP. In vascular cells, correspondence between AT(4) binding sites and insulin-regulated AP has been described. Angiotensin IV regulates cell growth in cardiac fibroblasts, endothelial cells, and vascular smooth muscle cells (VSMCs). In VSMC, AngIV, through AT(4), independently of AT(1) and AT(2) receptors, activates the nuclear factor-kappaB pathway and up-regulates several nuclear factor-kappaB-related genes, including the monocyte chemokine monocyte chemoattractant protein-1, the adhesion molecule intercellular adhesion molecule-1, and the cytokines interleukin 6 and tumor necrosis factor alpha. These data indicate that AngIV could be involved in the vascular inflammatory response. Thus, in endothelial cells and VSMC, AngIV up-regulates plasminogen activator inhibitor-1 expression and could participate in thrombus formation. These results reveal novel concepts of RAS in the cardiovascular system, suggesting that AngIV could play an active role in vascular diseases.
