Figure 5From: MicroRNA-9 regulates survival of chondroblasts and cartilage integrity by targeting protogeninmiR-9 and its target, PRTG is involved in chondrocyte apoptosis. Human articular chondrocytes isolated from biopsy normal cartilage were electroporated with Prtg or miR-9 in the absence or presence of IL-1β and expression levels of apoptotic genes were examined and represented as heat-map.Back to article page
