AIM: To observe the effect of E2F decoy DNA on proliferation and apoptosis of androgen-independent prostate cancer cell line PC-3M.METHODS: E2F decoy DNA,ARE decoy DNA and control decoy DNA were transfected into PC-3M cells with lipofectamine,respectively.Their effects on cell proliferation were detected by MTT assay.The changes of cell morphology were observed by inverted phase contrast microscope.The cell apoptotic rate was determined by flow cytometry(FCM) analysis and chromosome DNA ladder was detected by DNA gel electrophoresis.The expression of c-Myc mRNA and cyclin D1 mRNA was detected by RT-PCR.The protein levels of c-Myc and cyclin D1 were detected by Western blotting.RESULTS: The growth of PC-3M cells was inhibited after transfection.The transfected PC-3M cells displayed typical apoptotic morphological changes.The apoptotic rate was 26.35% and DNA ladder was observed after transfection.The expression of c-Myc and cyclin D1 were inhibited.CONCLUSION: These results indicate that E2F decoy DNA induces apoptosis of androgen-independent prostate cancer cell lines PC-3M and inhibits cell proliferation via inhibiting expression of c-Myc and cyclin D1.

AIM: To study the basic mechanism of transcriptional regulation,NKX3.1 gene promoter was cloned and its promoter activities in prostate cancer cell lines and other cancer cell lines were tested.METHODS:(1.04 kb)-promoter fragment of NKX3.1 gene was obtained by PCR and cloned into pGL_3-basic and pEGFP-1 that are promoter-less reporter vectors to examine its promoter activity driving the reporter gene transcription.The promoter activity was determined by dual-luciferase reporter assay and the expression of GFP reporter observed under fluorescence microscope.RESULTS: The sequence of the cloned(1.04 kb) promoter proved to be correct by DNA sequencing.The dual-luciferase reporter assay(M1/M2) showed that the promoter activity in LNCaP cell transfected with pGL_3-(1.04 kb) promoter was about 1.5-fold higher than that of pGL_3-control transfection and 50-fold higher than that of pGL_3-basic transfection.To investigate the 1.04 kb-promoter activity in different tumor cell lines,the constructed pGL_3-(1.04 kb) promoter and pEGFP-1.04 kb promoter were transfected into several cell lines,respectively.The results showed that the activity of(1.04 kb) promoter in LNCaP was highest among the tested cell lines.Multiple consensus sequence elements have been identified within the(1.04 kb) fragment using TRANSFAC database.Further experiments will be done to determine their founctions.CONCLUSION: Cloned 1.04 kb fragment upstream of NKX3.1 gene presented a strong promoter activity and its activity was highest in LNCaP cell among the tested tumor cell lines.

AIM: In order to evaluate the applicable value of LDL as a targeted vehicle for chemotherapeutic agents, we investigated and compared the inhibitory effects of LDL-ACM complex and free ACM on nude mice's subcutaneous implanted tumors derived from gastric cancer cell lines, SGC-7901 and NKM-45. METHODS: LDL-ACM complex was prepared and the tumor model of nude mice was established by subcutaneous implantation of SGC-7901 and NKM-45. Then, the groups of nude mice developed subcutaneous implanted tumors were received either LDL-ACM complex or free ACM. Subsequently, the tumor size, weight and leukemia cell counts were measured and the rates of tumor-inhibition and the survival were compared among the groups. RESULTS: The inhibitory effects of LDL-ACM complex on the tumors, especially on SGC-7901 implanted tumors were much more obvious than that of free ACM. It was also indicated that the action of LDL-ACM complex was mediated by LDL receptor. CONCLUSION: These results showed that LDL-ACM complex had significant inhibitory effects on the implanted tumors and the effect might be mediated by LDL receptor.
