In accordance with the transcript profiling results, expression of LGALS4 was highly and specifically expressed in MOC (median expression 72% of cells staining positive) compared to the other ovarian carcinoma subtypes (serous and endometroid, P<0.001; clear cell P=0.002) and to normal ovarian surface epithelium (P=0.002), all of which had a median expression equivalent to zero (Figure 4A). The gene discussed is LGALS4; the disease is ovarian carcinoma.
