Moreover, expression analysis between normal and tumor ovarian samples from three GEO datasets (GSES18520, GSE27651, and GSE54388) showed that HOXB7 expression was significantly increased in EOC tumors as two out of three GSE datasets showed significantly upregulated HOXB7 expression in EOC tumor samples (Figure 3A). The gene discussed is HOXB7; the disease is neoplasm.
