摘要

目的

我们前期的研究表明:iASPP在人头颈鳞状细胞癌（HNSCC）中表达升高

且iASPP过表达与HNSCC的恶性生物学行为及不良预后密切相关。本研究旨在探讨下调iASPP表达对体外培养的HNSCC细胞系Tu686增殖和侵袭的影响。

方法

采用慢病毒介导的特异性iASPP shRNA和control shRNA分别转染Tu686细胞

转染后的细胞分别作为shRNA-iASPP组和shRNA-NC组;未转染的Tu686细胞为CON组。采用CCK-8法、流式细胞术、Transwell侵袭实验检测下调iASPP基因表达对Tu686细胞的影响。

结果

CCK-8结果显示:shRNA-iASPP组细胞在转染后72 h（

=32.459

=0.000）、96 h（

=51.407

=0.000）、120 h（

=35.125

=0.000）的增殖明显低于shRNA-NC组和CON组。流式细胞术结果显示:shRNA-iASPP组细胞凋亡率为9.42%±0.39%（

=299.490

=0.000）

明显高于CON组（2.80%±0.42%）和shRNA-NC组（3.18%±0.28%）。shRNA-iASPP组中处于G0/G1期的细胞比例为74.65%±1.09%（

=388.901

=0.000）

明显高于CON组（55.19%±1.02%）和shRNA-NC组（54.62%±0.88%）。侵袭实验显示:shRNA-iASPP组的侵袭细胞数目为56±4

比CON组（111±3）和shRNA-NC组（105±8）显著降低（

=84.965

=0.000）。CCK-8实验结果表明:在紫杉醇作用下

shRNA-iASPP组细胞的存活率显著低于CON组和shRNA-NC组（

=634.841

=0.000）。

结论

iASPP在HNSCC的发生、发展中起重要作用

有可能成为增强头颈鳞状细胞癌对紫杉醇化疗敏感性的有效分子治疗靶点。

Abstract

Objective

Our previous study has revealed that iASPP is elevated in human head and neck squamous cell carcinoma (HNSCC) and iASPP overexpression signifcantly correlates with tumor malignant progression and poor survival of HNSCC. This study investigated the function of iASPP playing in proliferation and invasion of HNSCC

in vitro

Methods

HNSCC cell line Tu686 transfected with Lentiviral vector-mediated iASPP-specific shRNA and control shRNA were named the shRNA-iASPP group and shRNA-NC group

respectively. The non-infected Tu686 cells were named the CON group. CCK-8 assay

flow cytometry

transwell invasion assay were performed to detect the effects of iASPP inhibition

in vitro

Results

Our results demonstrated that the proliferation of shRNA-iASPP cells at the time of 72 h (

=32.459

=0.000)

96 h (

=51.407

=0.000)

120 h (

=35.125

=0.000) post-transfection

was significantly lower than that of shRNA-NC cells and CON cells. The apoptosis ratio of shRNA-iASPP cells was 9.42% ± 0.39% (

=299.490

=0.000)

which was significantly higher than that of CON cells (2.80% ± 0.42%) and shRNA-NC cells (3.18% ± 0.28%). The percentage of shRNA-iASPP cells in G0/G1 phase was 74.65% ± 1.09% (

=388.901

=0.000)

which was strikingly increased

compared with that of CON cells (55.19% ± 1.02%) and shRNA-NC cells (54.62% ± 0.88%). The number of invading cells was 56 ± 4 in the shRNA-iASPP group (

=84.965

=0.000)

which decreased significantly

compared with the CON group (111 ± 3) and the shRNA-NC group (105 ± 8). The survival rate of shRNA-iASPP cells administrated with paclitaxel was highly decreased

compared with CON cells and shRNA-NC cells (

=634.841

=0.000).

Conclusion

These results suggest iASPP may play an important role in progression and aggressive behavior of HNSCC and may be an efficient chemotherapeutic target for the treatment of HNSCC.
