Figure Lengend Snippet: The expression of TOR1 AIP1 was downregulated in prostate cancer samples. A The expression of TOR1 AIP1 in 499 tumor tissues and 52 normal tissues was analyzed by TCGA. B The expression level of TOR1 AIP1 was validated by qPCR using clinical samples ( n = 5). C The protein level of TOR1 AIP1 in human prostate tumor specimens was determined by WB ( n = 3). D The expression of TOR1 AIP1 in prostate cancer was examined by IHC ( n = 3). Normal group: Non-cancerous tissue adjacent to the tumor, Tumor group: neoplastic tissue. Compared with the indicated group, * P < 0.05, ** P < 0.01, and *** P < 0.001

Article Snippet: To further confirm that the p53 expression might serve as the molecular mechanism of TOR1 AIP1 involved in the development of PRAD, we used pifithrin-α (MedChemExpress, Shanghai, China), an inhibitor of p53 protein, to determine if it resulted in rescuing the effect of TOR1 AIP1 on tumor progression.
