Figure 1A shows the DCTPP1 expression profile in 33 cancers (GEPIA). Analysis of DCTPP1 expression in three Oncomine datasets relative to normal tissues revealed DCTPP1 overexpression in BRCA tissue relative to normal breast tissue (Figures 1B–D, p ≤ 0.01). Fold differences were all >1.5. Analysis of DCTPP1 expression in BRCA tumors vs. normal tissues using UALCAN revealed that regardless of age, gender, disease stage, nodal metastasis, major subclasses, or menopause status, DCTPP1 transcription levels were remarkably elevated in BRCA patients than in healthy controls (Figure 2). Here, DCTPP1 is linked to invasive breast carcinoma.
