Desmosome components are dysregulated in SG tumors compared with DG and normal pituitary. (a) Dot blots show the transcript expression on log-transformed scale for DSP, PKP2, and DSG2 (white indicates normal pituitary, gray indicates DG tumors, and black indicates SG tumors). (b) mRNA expression of desmosome components, DSP, PKP2, and DSG2, using qPCR. *P < 0.001, **P < 0.01, ***P = 0.03.
