Nasopharyngeal Angiofibroma: True Neoplasm or Vascular Malformation?

open access: closedAdvances in Anatomic Pathology, 2000
Nasopharyngeal angiofibromas (NA) are rare tumor-like lesions characterized by architecturally irregular vessels set in a fibrous stroma. The unique morphology, the strong predilection for male adolescents, and the uncertainty about its etiology contributes to significant confusion regarding the classification of NA, which still has not been solved ...

[Expression of NP9 gene in nasopharyngeal neoplasms and its effects on CNE1 cells growth].

open access: closedZhonghua yi xue za zhi, 2004
鼻咽癌是高发于中国南方的一种恶性肿瘤, 流行病学研究证实其发病与遗传密切相关.NP9基因是通过消减杂交和差异筛选法从鼻咽癌组织中克隆的一个长度大约为2000 bp的新基因片段(GenBank 登录号: BF718797 ), 该基因在鼻咽癌组织和细胞系中呈现表达下调情况[1].研究结果已证实NP9基因在鼻咽癌细胞中可通过下调NF-κB的转录活性来抑制细胞周期素D1的转录活性[2].为进一步确定NP9基因在鼻咽癌中的表达及其对鼻咽癌细胞生长的影响,我们检测了鼻咽癌和其他肿瘤组织中NP9基因的表达情况,并通过细胞增殖和裸鼠致瘤实验观察NP9基因的表达对鼻咽癌细胞生长的影响。
