Title: [Study in vitro on p16beta interfering the cell cycle signal conduction of laryngeal squamous cell carcinoma].
Abstract: To investigate the effect of p16beta interfering with the signal conduction of Hep-2 cell cycle in Vitro.AdEasy Vector System was used to construct the recombinant adenovirus vector AdEasy-GFP-p1613. The recombinant adenovirus vector could introduce p16beta gene into HEK 293 cell. Then the purified recombinant adenovirus was used to infect Hep-2 cells in vitro. The protein expression of p16beta, proliferation inhibition, cell cycle arrest, DNA content, apoptosis ratio in Hep-2 cells were examined by MTT, Western blotting analysis, Flow cytometry assay, Immunocytochemistry respectively.The recombinant adenovirus Adeasy-p16beta was constructed successfully and higher titer recombinant adenovirus particle was got. When Adeasy-p16beta was transferred into Hep-2 cells, both the growth inhibition and P14 (ARF) protein overexpression in Hep-2 cells were visible effectively. The most Hep-2 cells were blocked in G1/G0 phase and the cell apoptosis ratio increased.The p16beta in Hep-2 cell infected by recombinant adenovirus, which lead to express P14 (ARF) protein effectively and to inhibit cell proliferative activation, effectively interfere the signal conduction mechanisms of culture Hep-2 laryngeal squamous cell carcinoma, and the growth of much cultured cells is blocked in G1/G0 phase.
