2011, Yang et al. 2019), breast cancer (Wang et al. 2010) and sarcoma (Cattaruzza et al. 2013). Thus, Cattaruzza et al. pointed out phosphorylation of FAK as a downstream result of interactions between CSPG4 and collagen VI, promoting migration and invasion (Cattaruzza et al. 2013) and Yang, et al. showed that a pointmutation in CSPG4 reduced malignant melanoma cell survival and decreased phosphorylation of FAK and ERK (Yang et al. 2019). Here, CSPG4 is linked to sarcoma.
