FOXI3 and neoplasm: Thus, we propose that when FOXI3 in tumor cells modulate the secretion of other bone factors including SPOCK1, Dlx, MAF, PthrP, HAS2, SVEP1, TGFβ3, and FGF (Jussila et al., 2015; Meng et al., 2016; Shirokova et al., 2016) which further primes the microenvironment, creates a crosstalk to help tumors grow in the bone (Figure 5).
