P53 is an index to check whether it is cancerous. If it is positive, it means it is malignant. Now negative (-) means normal.
Calponin is a small (slightly white) protein, which can combine actin, calmodulin, troponin C and myosin to participate in cytoskeleton formation, muscle contraction and cell adhesion, and may play an important role in the occurrence, development and metastasis of tumors.
P63, a member of P53 gene family, is a sensitive and specific marker of myoepithelial cells. The intensity of positive expression is negatively correlated with the prognosis of patients and can be used as an independent prognostic indicator.
