WNT4 and neoplasm: Comparison of control tissues to the tissues of the patients with inner half of the myometrium occupied by the tumor or to the tissue of patients where the tumor invades the outer half of the myometrium showed decreased abundance of the WNT4 transcripts in tumor groups (C vs. <50%, p < 0.001; C vs. >50%, p < 0.001; Figure 1F).
