Changes in cell proliferation, apoptotic rate and invasiveness were detected by MTT assay, flow cytometry (FCM) and matrigel in vitro invasion assay, respectively. It was found that DRB inhibited the proliferation of Hep-2 cells in a dose- and time-dependent manner. After being treated with 0, 10, 20, 40, 80 μmmol/L DRB for 24 h, the apoptotic rate in Hep-2 cells was (0.68±0.19)%, (1.95±0.12)%, (8.51±0.26)%, (11.26±0.17)% and (14.99±0.32)%, respectively. The matrigel in vitro invasion assay revealed that DRB began to inhibit the invasion of Hep-2 cells at the concentration of 5 μmmol/L, and with the increase of DRB concentration, the inhibitory effect was enhanced. It was suggested that DRB could influence the essential biological characteristics of Hep-2 cells, inhibit Hep-2 cells proliferation, reduce invasive ability and induce apoptosis of Hep-2 cells.展开更多

Methods:...Objective: To locate lost region of tumor suppressor gene on chromosome 13q in squamous cell carcinoma of the larynx (LSCC) and to provide clues and evidence for discovering and locating new suppressor gene. Methods: Loss of heterozygosity (LOH) on chromosome 13q was analyzed in 58 LSCC patients by microsatellite polymorphic sequences in loci D13S765 (13q13), RB120 (13q142), D13S133 (13q143) and D13S318 (13q21) on chromosome 13 by PCR. Results: There weren't any LOH on chromosome 13q in 3 cases with preinvasive LSCC. Fortyfive percentage (24/53) of the 53 invasive LSCC cases showed LOH at one or more loci on chromosome 13q region. The highest percentage of LOH on chromosome 13q was 52% (22/53) at D13S765 locus. Conclusion: The deletion region on chromosome 13q was located near by D13S765 locus which is centromeric to RB1. In this region there is suppressor gene, which is related to the genesis and development of LSCC, possibly including RB1. The inactivation of these suppressor genes may be related to the genesis and development of invasive LSCC.展开更多

RNA interference (RNAi) technology has emerged as a very potent tool to generate cellular knockdown phenotypes of a desired gene. The aim of this study was to explore the effect of siRNA specific to the protein casein kinase 2α (CK2α) on apoptosis of laryngeal carcinoma cells and to explore possible mechanisms.Methods An siRNA expression plasmid specific to CK2α, psiRNA-hH1neo-CK2α, and a non-specific siRNA expression plasmid, psiRNA-hH1neo-cont, were constructed and transfected into Hep-2 cells by a lipofectamine method. The mRNA and protein levels of CK2α in transfected cells were determined by reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting analysis. Apoptosis was measured by Annexin V-fluorescein isothiocyanate (FITC)/ propidium iodide (PI) double-staining methods. The morphological changes to Hep-2 cells were observed under transmission electron microscopy (TEM). The levels of Bcl-2 and Bax proteins were measured by Western blotting analysis.Results Levels of CK2α mRNA and protein were significantly decreased in the psiRNA-hH1neo-CK2α group compared to the other groups (P 〈0.05). The apoptotic rate of the psiRNA-hH1neo-CK2α transfected group was significantly higher compared to that in the untransfected group and the siRNA-hH1neo-cont transfected group (25.66%±0.83%, 3.66%±0.43%, and 5.18%±0.22%) (P 〈0.05). Compared with the untransfected group and the siRNA-hH1neo-cont transfected group, the psiRNA-hH1neo-CK2α transfected group presented with classical ultrastructural features of apoptosis, such as karyopyknosis, chromatic agglutination adjacent to the nuclear membrane, and apoptotic bodies. Compared with the other two groups, the level of Bcl-2 protein in the psiRNA-hH1neo-CK2α transfected group was decreased (0.20±0.09 vs. 0.72±0.16, 0.56±0.11, P 〈0.01), while the Bax protein level was increased (0.81±0.17 vs. 0.26±0.12, 0.33±0.17, P 〈0.01) and the ratio of Bcl-2 to Bax was decreased (0.25±0.05 vs. 2.76±0.21, 1.70±0.22, P 〈0.01).Conclusions The siRNA expression plasmid specific to CK2α could suppress CK2α expression and induce the apoptosis of laryngeal carcinoma cells. This is possibly by decreasing the Bcl-2/Bax ratio. CK2α may provide a potential therapeutic target against human laryngeal carcinoma.展开更多

Methods: We retrospectively analyzed five male patients with confirmed ASC of the larynx between 2005 and 2010 in our hospital, accounting for 0.2% of the laryngeal malignant tumors in the same period. Results: All patients underwent surgeries including horizontal partial laryngectomy(2 cases), vertical partial laryngectomy(1 case) and total laryngectomy(2 cases). One of the two who underwent total laryngectomy also received post-operative chemoradiotherapy. Four also underwent neck dissections. The mean follow-up time was 77.4±14.98 months. At the end of follow-up, two suffered regional metastasis and another local relapse. They all underwent related operations again and were still alive. The therapeutic approach might follow that of squamous cell carcinoma of the larynx. Conclusion: Our limited cases suggest that the prognosis of adenosquamous carcinoma of the larynx is similar to that of squamous cell carcinoma of the larynx.展开更多
