Reinartz et al. (2016) observed a slight but non-significant higher level of ALOX15B expression in TAMs, when compared to ovarian carcinoma tumors. Indeed Roffeis et al. (2007) revealed an increase of ALOX15B expression in ovarian tumors in comparison to normal ovarian tissue, however the precise cell type that expresses ALOX15B was not determined. The gene discussed is ALOX15B; the disease is ovarian neoplasm.
