HDAC6 and chondrosarcoma: The inhibition of intracellular HDAC6 activity can affect the acetylation modification of ciliary microtubules, which can regulate primary cilia assembly in chondrosarcomas through the Aurora A‐HDAC6 signal cascade and eventually downregulate the malignant properties of chondrosarcomas.102 Meanwhile, inhibition of the Hedgehog pathway can suppress the proliferation, migration and invasion capacities of malignant chondrosarcoma cells by disturbing ciliogenesis.103
