這些研究結果發表了40篇SCI收錄的論文,比較重要的發現:1.
miRNA-21負調控BTG2加速細胞周期G1/S期轉換,促進腫瘤細胞生長從而發揮癌基因的作用(Liu M, Wu H, Liu T, Li Y, Wang
F, Wan H, Li X, Tang H. Regulation of the cell cycle gene, BTG2, by miR-21 in
human laryngeal carcinoma. Cell Res, 2009, 19(7): 828-837);2.
首次發現調節NF-kB1的miRNA-9, 并確定miRNA-9在胃癌中下調表達,解除了對NF-kB1抑制作用,促進了腫瘤細胞生長(Wan HY, Guo
LM, Liu T, Liu M, Li X, Tang H. Regulation of the transcription factor NF-κB1 by
microRNA-9 in human gastric adenocarcinoma. Molecular Cancer, 2010, 9(16):1-10.
); 3. miR-372在宮頸癌中低表達,使其細胞周期靶CDK2和Cyclin A1增高表達, 從而促進腫瘤細胞生長發揮抑癌基因作用(Tian RQ,
Wang XH, Hou LJ, Jia WH, Yang Q, Li YX, Liu M, Li X, Tang H. MicroRNA-372 is
down-regulated and targets cyclin-dependent kinase 2 (CDK2) and cyclin A1 in
human cervical cancer, which may contribute to tumorigenesis. J Biol Chem. 2011
286(29):25556-63); 4.
首次發現GALNT7在宮頸癌中具有癌基因作用,受到miRNA-214的負調控,并促進癌細胞的增殖與侵襲轉移能力(Peng RQ, Wan HY, Li HF,
Liu M, Li X, Tang H. MicroRNA-214 Suppresses The Growth and Invasiveness of
Cervical Cancer Cells by Targeting UDP-N-acetyl-alpha-D-
galactosamine:polypeptide N-acetylgalactosaminyltransferase 7. J Biol Chem. 2012
287(17): 14301–14309); 5.與南開大學合作確定了甘草次酸作為肝癌靶向給藥的作用(Qin Tian, Chuang-Nian Zhang,
Xiu-Hua Wang, Wei Wang, Wei Huang, Zhi Yuan, Min Liu, Hai-Ying Wan, Hua Tang.
Glycyrrhetinic acid-modified chitosan/poly(ethylene glycol) nanoparticles for
liver-targeted delivery. Biomaterials. 2010;
31(17):4748-56)。這些研究發現對于揭示腫瘤細胞調控機制提供了新的分子途徑,并可能為腫瘤診斷、治療提供新的生物標志物。
