Figure 5

Analysis of the knock-down of TPD52 and TPD54 in ATDC5 cells. Control, TPD52, and TPD54 siRNAs were transfected into ATDC5 cells, and the cells were subjected to DNA (a), GAG (b), ALPase activity (c), Ca deposition (d), measurements, as well as RT-qPCR for type II collagen (e), aggrecan core protein (f), ALPase (g), and type X collagen (h). For RT-qPCR, the value of the control was designated as “1,” and relative values are shown. Data are shown as the mean with the standard deviation of three sets of cultures. versus the control.
