Notably, overexpression of TPX2 increased the subcutaneous growth of LNCaP cells and enhanced the expression of PSA in tumor tissues (Figures 7(a)–7(d)), whereas knockdown of TPX2 decreased the subcutaneous growth of LNCaP cells and the expression of PSA (Figures 7(a)–7(d)). The gene discussed is TPX2; the disease is neoplasm.
