【摘要】:背景和目的肺癌是目前是全世界腫瘤性疾病死亡率的主要原因,每年可造成多于150萬(wàn)人死亡。目前多數(shù)肺癌患者明確診斷時(shí)已是晚期,臨床癥狀不明顯、早期診斷困難,組織學(xué)亞型不同、對(duì)腫瘤生物學(xué)特征的認(rèn)識(shí)不足導(dǎo)致了肺癌的預(yù)后不良及高死亡率。雖然新的分子靶向治療對(duì)于某些類(lèi)型的肺癌的療效表現(xiàn)出非?捎^的前景,但目前還沒(méi)有適用于大規(guī)模的肺癌病人的靶向治療?傮w來(lái)說(shuō),肺癌的總體生存率依然不容樂(lè)觀,很多患者明確診斷后生存期僅僅短短數(shù)月。因此,尋找新型肺癌診斷相關(guān)的腫瘤標(biāo)記物或新的治療策略對(duì)于肺癌的控制顯得至關(guān)重要。miRNA是一段大約由19到25個(gè)核苷酸組成的非編碼小RNA,通過(guò)對(duì)其靶m RNA的翻譯抑制或者降解在動(dòng)植物體內(nèi)發(fā)揮重要的調(diào)節(jié)作用。miRNA是多細(xì)胞生物體內(nèi)眾多基因調(diào)控分子的重要組成部分之一,同時(shí)很可能影響著許多蛋白編碼基因的表達(dá)輸出。miRNA按照其在腫瘤的發(fā)生發(fā)展中的調(diào)控作用可分為致癌miRNA和抑癌miRNA,調(diào)控癌細(xì)胞的增殖、侵襲、凋亡及血管生成情況。miRNA的表達(dá)模式可能與肺癌亞型中臨床病理特征有關(guān),提示了miRNA作為生物標(biāo)志物在腫瘤起源、組織學(xué)類(lèi)型、侵襲性和化學(xué)敏感性等分型中的應(yīng)用潛力?偟膩(lái)說(shuō),涉及肺癌的miRNA范圍廣泛,let-7家族、miR-34、miR-200、miR-126等miRNAs在肺癌中的作用已被廣泛研究。通過(guò)查閱相關(guān)文獻(xiàn)及搜索miRBase數(shù)據(jù)庫(kù),發(fā)現(xiàn)miR-339在甲狀腺癌、肺癌、卵巢癌、胃癌等多種腫瘤生長(zhǎng)及侵襲中起到負(fù)向調(diào)控作用。miR-339如何調(diào)控腫瘤的生物學(xué)行為,其具體作用機(jī)制尚未闡明,且miR-339在肺癌尤其是臨床肺癌組織中的表達(dá)情況亦較少研究。目前多數(shù)研究者認(rèn)為腫瘤的生長(zhǎng)必須依靠新生血管的生成來(lái)提供其足夠的氧氣和營(yíng)養(yǎng)物質(zhì),因此以抗腫瘤血管為主的治療成為腫瘤臨床治療的熱點(diǎn),血管內(nèi)皮生長(zhǎng)因子(vascular endothelial growth factor,VEGF)被認(rèn)為可作用于血管內(nèi)皮細(xì)胞,誘導(dǎo)體內(nèi)新生血管生成。抑制VEGF的作用也成為了抑制腫瘤生長(zhǎng)的臨床研究基礎(chǔ)。當(dāng)VEGF與特異性的VEGF受體結(jié)合后,會(huì)發(fā)生一系列的生物效應(yīng),能促進(jìn)血管內(nèi)皮細(xì)胞增殖誘導(dǎo)新血管的生成;增加血管通透性;改變血管內(nèi)皮細(xì)胞的基因及其表達(dá),利于新血管的形成。本研究通過(guò)miRNA的靶基因預(yù)測(cè)數(shù)據(jù)庫(kù)對(duì)miR-339的靶基因進(jìn)行預(yù)測(cè),對(duì)3種靶基因預(yù)測(cè)數(shù)據(jù)庫(kù)所預(yù)測(cè)的靶基因交集進(jìn)行功能分析,最終篩選出VEGF作為miR-339的靶基因進(jìn)行研究。本課題分為三個(gè)部分:第一部分通過(guò)qRT-PCR及Western

[Abstract]:Background and objective lung cancer is the main cause of mortality in all the world's Oncology, which can cause more than 1 million 500 thousand deaths a year. At present, most patients with lung cancer are clearly diagnosed at the present time, the clinical symptoms are not obvious, the early diagnosis is difficult, the histologic subtypes are different, and the lack of understanding of the biological characteristics of the tumor leads to the prognosis of lung cancer. Poor and high mortality. Although new molecular targeting therapy has shown great prospects for the efficacy of some types of lung cancer, it is not yet suitable for targeted therapy for large scale lung cancer patients. Overall, the overall survival rate of lung cancer is still not optimistic, and many patients have a clear diagnosis of only a few months after the diagnosis. Therefore, looking for tumor markers related to new lung cancer diagnosis or new treatment strategies is important for the control of lung cancer..miRNA is a non coded small RNA, which is composed of approximately 19 to 25 nucleotides, and the.MiRNA is a multicell organism by inhibiting or degradation of the target m RNA. One of the most important components of a number of gene regulatory molecules in the body is likely to affect the expression of a number of protein encoding genes, which can be divided into carcinogenic miRNA and tumor suppressor miRNA in accordance with its regulatory role in the development of tumor, and the expression pattern of.MiRNA, which regulates the proliferation, invasion, apoptosis and angiogenesis of cancer cells, may be regulated. It is associated with the clinicopathological features of lung cancer subtypes, suggesting the potential application of miRNA as a biomarker in tumor origin, histologic type, invasive and chemosensitivity isoforms. Generally, the miRNA range involving lung cancer is wide, and the role of miRNAs in the let-7 family, miR-34, miR-200, miR-126 and other miRNAs in lung cancer has been widely studied. After consulting related literature and searching for miRBase database, it is found that miR-339 plays a negative regulatory role in the growth and invasion of thyroid cancer, lung cancer, ovarian cancer and gastric cancer, and how.MiR-339 regulates the biological behavior of the tumor. Its specific mechanism has not been elucidated, and the expression of miR-339 in lung cancer, especially in lung cancer tissues At present, most researchers believe that the growth of tumor must rely on the formation of new blood vessels to provide enough oxygen and nutrients. Therefore, the antitumor vascular therapy has become a hot spot in the clinical treatment of tumor. Vascular endothelial growth factor (VEGF) is considered to be a function of blood vessels. Endothelial cells, which induce neovascularization in the body, inhibit the role of VEGF as a basis for the inhibition of tumor growth. When VEGF is combined with a specific VEGF receptor, a series of biological effects will occur, which can promote the proliferation of vascular endothelial cells to induce the generation of new blood vessels, increase vascular permeability, and change vascular endothelial cells. Gene and its expression are beneficial to the formation of new blood vessels. In this study, the target gene of the target gene of miR-339 was predicted by the target gene prediction database of miRNA, and the target gene intersection predicted by the 3 target gene prediction database was analyzed. Finally, the target gene of VEGF was selected as the target gene of miR-339. The subject was divided into three parts: the first part The expression level of miR-339 and VEGF in 41 cases of lung adenocarcinoma was analyzed by qRT-PCR and Western blot. The second part of the lung adenocarcinoma A549 cell line with high expression of miR-339 was established by lentivirus vector technology, and the effects of the up regulation of miR-339 expression on the A549 cell proliferation, invasion, chemosensitivity and angiogenesis of lung adenocarcinoma in vivo and in vivo were studied. The third part, through the double Luciferase Report experiment and the Restore experiment, further studies the regulatory mechanism of miR-339 after VEGF transcription. Part 1: analysis of the expression level of miR-339 and VEGF in 41 cases of lung adenocarcinoma 1. to collect 41 cases of lung adenocarcinoma tissue and the corresponding paired normal tissue specimens of the paracancerous tissue,.2. using qRT-PCR technique to detect 41 cases.

The LSD-t test is used for 22 comparison of multiple groups of data; t test is used for comparison of two independent sample data and paired t test For comparison of two paired sample data, Spearman correlation analysis was used for correlation analysis of two groups of data. The expression of 1.miR-339 in lung cancer tissue was approximately 1/3 in the normal tissues adjacent to cancer, while the expression level of VEGFm RNA was 3 times as high as that of normal tissue adjacent to the cancer, and there was a negative correlation between the level of expression of the two groups. The expression level of r=-0.419, P=0.006.2.miR-339 and VEGFmRNA in the lung adenocarcinoma tissues of different TNM staging and lymph node metastasis was statistically significant (P0.05). Second part up regulation of miR-339 expression on the proliferation, invasion, chemosensitivity and angiogenesis of A549 cells of lung adenocarcinoma 1. preparation and packaging miR-339 and unrelated order The expression vector of lentivirus was used to infect A549 cells of lung adenocarcinoma and to establish a A549 cell line with high expression of miR-339 in lung adenocarcinoma. The expression of miR-339 and VEGFmRNA in three groups was detected in group miR-339, NC and Blank, and Western blot was used to detect the VEGF protein and invasion related protein. Cell proliferation ability.4.Transwell cell detection of three groups of cell invasiveness.5.CCK-8 detection of the proliferation ability of three groups of cells under the action of cisplatin and.6. to establish a nude mouse transplanted tumor model.
