Purpose:During the malignant transformation, most tuomr cells will become resistant to anoikis (the apoptosis induction upon loss of anchorage), thereby gaining an important growth advantage and providing the basis for tumor spread, growth at distant places, and formation of metastasis.The present study focus on the role of soluble fibronectin, integrin and their signal transduction in the process of tumor cells anoikis apoptosis.Methods:Flow cytometry detected integrin subunits' expression on the human squamous cell carcinoma cell (HSC 3) surface. Establish anoikis induction model. The role of different integrin subunits during anoikis induction were detected by antibody blocking method, p53 and Bcl 2/Bax expression were measured during this anoikis process.Results:There is no or low expression of integrin av on the normal epithelial cells, whilst it expresses relative higher on the surface of HSC 3 cells. The treatment of soluble fibronectin decreased p53 expression, increased the ratio of Bcl 2/Bax and then protected HSC 3 cell from anoikis. Anti integrin ?v blocking antibody resumed the anoikis that was inhibited by soluble fibronectin evidently. Conclusions:We now provide the evidence that the binding of integrin ?v and soluble fibronectin protected HSC 3 cells from anoikis apoptosis, via decreasing the expression of p53, increase the ratio of Bcl 2/Bax.

Objective: To study the characterization of the cultured cervical cancer cell line transfected with anti- HPV16E6-ribozyme, and to investigate the effect of ribozyme on proliferation and apoptosis of cervical cancer cell. Metliods: Anti-HPV16E6-ribozyme had been designed to cleave the HPV16E6 gene. With the method of lipofectin transfec- tion, the anti-HPVI6E6-ribozyme and empty eucaryotic expressing plasmids were transfected into CaSKi cell, which named as CaSKi-R, CaSKi-P respectively. The amounts of E6 mRNA in the three kinds of cells were detected by northern blot. Cell cycle was detemined by flow cytometry, and cell apoptosis was examined by fluorescent (Hoechst) staining and TUNEL. The expression of some genes, including c-myc, bcl-2, p53, and fas, was also detected by flow cytometry analy- sis. Results: Northern blot showed that E6 mRNA was less in CaSKi-R than in CaSKi. In CaSKi-R cells, cycle was arres- ted in G1 phase, with decreasing in percentage of S phase cells. The apoptosis rate of CaSK1-R cell was much higher than those of CaSKi and CaSK1-P. Anti-HPV16E6-ribozyme could reduce the expression of E6, c-myc, bcl-2 genes on CaSKi- R cells, and increased the expression of p53. While this phenomenon was not found on the CaSK1-P cells. The expression of fas was similar in the three kinds of cells. Conclusion: Anti-HPVE6-rivozyme induces apoptosis of human cervical cancer CaSKi cells. The mechanisms may be the decrease of E6 gene's expression, and the succedent changing of some genes'expression.

Objective: To investigate the effects of HPV16E6-ribozyme on telomerase activity in cervical carcinoma cell line CaSKi and the related mechanisms. Methods: Anti-HPV16E6-ribozyme and blank eucaryotic plasmids were transfected into CaSKi cells via lipofectin, and the resultant cells were named as CaSKi-R and CaSKi-P, respectively. The expression of ribozyme in transfected cells was observed by RNA dot blotting. The expression of E6 mRNA and protein in the 3 kinds of cells were detected by Northern blotting and Western blotting, respectively. Telomerase activity was determined by TRAP-Elisa method; the expression of P53, c-myc, hTERT and hRT mRNA were examined by RT-PCR.Results: RNA dot blotting showed that anti-HPV16E6-ribozyme was stably expressed in transfected CaSKi-R cells. Western blotting showed that the expression of E6 mRNA and protein in CaSKi-R cells was obviously lower than that in CaSKi and CaSKi-P cells. The telomerase activities in CaSKi,CaSKi-P and CaSKi-R cells were (0.89?0.14), (0.90?0.11) and(0.36?0.06),respectively. The inhibitory rate of telomerase activity in CaSKi-R cells was 59.55%, which was significantly lower than those in CaSKi and CaSKi-P cells (P

Objective: To investigate the characteristics of the cultured cervical cancer cell line transfected with anti HPV16E6 ribozyme, and to investigate the possibility and practicality of ribozyme in treatment of cervical cancer. Methods: The anti HPV16E6 ribozyme and empty eucaryotic expressing plasmids were transfected by lipofectin transfection into CaSKi cell, which named as CaSKi R, CaSKi P respectively. The morphology and the soft agar forming ability were studied. The expression of E6, PCNA and C erbB 2 genes was studied through Flow Cytometry. The tumorgenicity of each cell was detected by injecting cells into the nude mice skin. Three groups of nude mice were injected by CaSKi, CaSKi R and CaSKi P cell separately. Another group of mice was injected by CaSKi cell on right side and CaSKi R cell on left side. Results: There is no distinct difference of the morphology and growth rate between CaSKi and CaSKi P, but the growth rate of CaSKi R decreased. The soft agar forming rate of CaSKi P was similar with that of CaSKi cells, while that of CaSKi R was found decreased. The result of flow cytometric analysis showed that anti HPV16E6 ribozyme could reduce the expression of E6, PCNA and C erbB 2 genes on CaSKi R cells, while this phenomenon was not found on the CaSKi P cells. The tumorgenicity of CaSKi R in nude mice was decreased compared with CaSKi and CaSKi P cells. Conclusion: Anti HPVE6 rivozyme could partly reverse the malignant phenotypes of CaSKi cells. The reason may be the decrease of E6 gene expression, and the succeeding decrease of the PCNA and C erbB 2 genes′ expression.

Objective To evaluate the indeterminate growth mutant of tomato derived by space mutagenesis to provide the basis for selecting and cultivating the molecular markers of tomato growth habit. Methods Fifty 10-mer randomly amplified polymorphic DNA(RAPD) primers were used to examine the polymorphism of M1 and 10-3-2. Their polymorphic fragments were cloned, and then were transferred to SCAR markers. Results Of all the 50 10-mer RAPD primers, 44 primers amplified polymerase chain reaction(PCR) products and 2 primers (S165 and S168) amplified stable reproducible polymorphic products. The molecular weight of the specific amplified products were 300 bp and 1 500 bp respectively, therefore they were named as TRS165300 and TRS1681500 temporarily. And TRS1681500 was transferred into stable sequence characterized amplified region(SCAR) marker and this marker could be a specific genetic marker of this indeterminate growth habit mutant. Conclusion Space mutation can produce mutants at DNA level from the loaded materials. The indeterminate growth mutant of tomato is derived by space mutagenesis which can provide a valuable material for studying the regulation and control of tomato growth habit.
