A Novel Rose Hip Preparation with Enhanced Anti-Inflammatory and Chondroprotective Effects

Figure 3

Effect of RH preparations on expression levels in human primary chondrocytes. NHAC-kn cells were stimulated with IL-1β for 4 h and the expression levels of indicated genes were quantified by RT-PCR. Triangles on y-axis indicate the expression levels in IL-1β only treated NHAC-kn. Straight line: RH-A; dashed line RH-B. , (IL-β only versus IL-1β + RHP). and indicate the differences between RH-A and RH-B.
