Label-Free Proteomics of Oral Mucosa Tissue to Identify Potential Biomarkers That Can Flag Predilection of Precancerous Lesions to Oral Cell Carcinoma: A Preliminary Study

Figure 6

Principal component analysis of differentially expressed proteins across (a) control, leukoplakia, and cancer; (b) control, erythroplakia, and cancer. Control and cancer phenotypes form well-segregated distinct cluster, whereas erythroplakia phenotypes show higher overlap with the cancer cluster, as compared to leukoplakia.
