Tóm tắt

Topoisomerase IIα (topo IIα) là một mục tiêu quan trọng cho một số tác nhân hóa trị, bao gồm etoposide và doxorubicin. Các tế bào đông đặc biểu hiện mức độ thấp của topo IIα và kháng lại điều trị bằng etoposide. Sự ức chế phiên mã trong các tế bào đông đặc được trung gian bởi sự liên kết của yếu tố phiên mã NF-Y với các mô hình CCAAT đảo ngược trong trình khởi động topo IIα. Để chặn sự liên kết ức chế của NF-Y, một polyamide (JH-37) đã được thiết kế để liên kết với các vùng lân cận của các điểm CCAAT đã chọn trong trình khởi động topo IIα. Các thử nghiệm dịch chuyển điện di và thử nghiệm dấu chân DNase I cho thấy sự chiếm giữ các vị trí CCAAT đảo ngược bởi JH-37. Các thử nghiệm kết tủa miễn dịch cromatin xác nhận sự ức chế trong vivo đối với sự liên kết của NF-Y với trình khởi động topo IIα. Sau khi ấp ủ các tế bào NIH3T3 đông đặc với JH-37, việc tăng cường biểu hiện mRNA và protein topo IIα đã được phát hiện. Điều này tương quan với việc tăng cường đứt gãy DNA cặp sợi đôi như được chỉ ra bởi thử nghiệm comet và giảm khả năng sống sót của tế bào sau khi tiếp xúc với etoposide. Polyamide có thể điều chỉnh biểu hiện gen và nhạy cảm hóa trị của các tế bào ung thư. [Mol Cancer Ther 2007;6(1):346–54]
