HOXB8 and ovarian carcinoma: We also observed upregulated expression of HOXB7 and HOXB8 in EOC tumor samples as well as the association between HOXB7 and HOXB8 expression and overall survival for EOC patients, the results are consistent with previous findings for HOXB7 and HOXB8 in various human cancers including ovarian cancer (Errico et al., 2016; Monterisi et al., 2018; Chen et al., 2020; Ying et al., 2020).
