Objective: To study the change of pituitary tumor transforming gene 1 (PTTG1) expression in prostate cancer and its correlation with proliferation and invasion genes. Methods: Patients with prostate cancer who underwent radical operation in our hospital between March 2015 and January 2018 were selected as the malignant group of the research, and the prostate cancer lesions were collected; patients who underwent transurethral resection of the prostate due to benign prostatic hyperplasia in our hospital during the same period were selected as the benign group of the research, and the benign prostate lesions were collected. The mRNA expression levels of PTTG1, proliferation genes and invasion genes in the lesions were determined. Results: PTTG1, Survivin, Bcl-2, CyclinD1, GPRC6A, ZEB1, CatB, CatD and PAR-1 mRNA expression in prostate cancer lesions of malignant group were significantly higher than those of benign group whereas CDKN2, p21 and TFPI2 mRNA expression were significantly lower than those of benign group; Survivin, Bcl-2, CyclinD1, GPRC6A, ZEB1, CatB, CatD and PAR-1 mRNA expression in prostate cancer lesions with high PTTG1 were significantly higher than those in prostate cancer lesions with low PTTG1 whereas CDKN2, p21 and TFPI2 mRNA expression were significantly lower than those in prostate cancer lesions with low PTTG1. Conclusion: The PTTG1 gene is highly expressed in prostate cancer lesions and it is closely related to the changes of proliferation and invasion gene expression.
