【摘要】：腎細胞癌(renal cell carcinoma,RCC)是起源于腎小管上皮的惡性腫瘤,占腎臟惡性腫瘤的80%-90%,是成人泌尿系統(tǒng)常見的惡性腫瘤之一[1]。腎細胞癌的生物學行為及其特征較為復雜,其發(fā)生發(fā)展的機制尚未完全明確。目前,外科手術(shù)是根治腎細胞癌的主要方法,約有1/3的腎細胞癌患者初次就診時就已發(fā)現(xiàn)有轉(zhuǎn)移,無法接受根治性手術(shù)治療[2],約有1/3的局限性腎癌患者行根治性手術(shù)后仍會出現(xiàn)遠處轉(zhuǎn)移[3],對于局限性腎癌患者,行根治性腎切除術(shù)或保留腎單位手術(shù)后,約90%以上患者能獲得五年無病生存。同時,轉(zhuǎn)移性腎癌(metastatic renal cell carcinoma,mRCC)對傳統(tǒng)放化療均不敏感,其5年生存率小于10%[4]。因此,探索腎細胞癌發(fā)生、發(fā)展的分子機制,尋找有效的生物學標記物,已成為腎細胞癌研究的熱點,以便為腎細胞癌的生物治療提供新的靶點和新思路。近年來分子靶向藥物治療成為腫瘤治療的熱點,并已在多種腫瘤的治療中獲得了重大進展,已成為抗腫瘤治療的重要組成部分[5]。分子靶向治療是以腫瘤細胞中過度表達的某些標志性大分子物質(zhì)作為靶點,利用藥物阻斷這些大分子物質(zhì)相關(guān)的信號轉(zhuǎn)導路徑,從而得到控制腫瘤的生長、進展及轉(zhuǎn)移等作用。研究發(fā)現(xiàn)缺氧誘導因子(hypoxia-inducible factor, HIF)、血管內(nèi)皮生長因子(vascular endothelial growth factor,VEGF)、血小板衍生生長因子(platelet-derived growth factor, PDGF)、表皮生長因子(epidermal growth factor, EGF)及其受體(EGFR)、哺乳動物雷帕霉素靶蛋白(mammalian target of rapamycin,mTOR)等均為分子靶向治療的重要靶向分子。這些分子的異常表達與腎癌特別是腎透明細胞癌的預(yù)后有著密切關(guān)系,使之成為腎細胞癌分子靶向治療的基礎(chǔ)和作用靶點。RCC分子靶向治療中最為重要的分子信號通路主要包括VEGF通路和mTOR通路。VEGF是腫瘤誘導產(chǎn)生新生血管的關(guān)鍵細胞因子,研究發(fā)現(xiàn)在腎細胞癌組織中VEGF、VEGFR-1、VEGFR-2mRNA異常高度表達,同時腫瘤組織中的微血管密度顯著大于正常腎組織[6,7]。VEGF與其受體結(jié)合后可激活細胞內(nèi)信號傳導通路,包括PI3K/Akt/mTOR和Ras/Raf/絲裂原激活蛋白激酶的激酶(mitogen activated protein kinase kinase,MAPKK)/細胞外信號調(diào)節(jié)激酶(extracellular signal regulated kinase, ERK)等信號通路,促進內(nèi)皮細胞的增生和分化,進而廣泛參與腎癌的生長、增殖、分化等過程。SARM(Sterile-alpha and HEAT/Armadillo motif containing protein)是 TLR(Toll-like receptor)信號通路中含有 TIR (Toll/interleukin-l receptor)結(jié)構(gòu)域的五個接頭蛋白之一,其在進化上非常保守,從線蟲、果蠅、文昌魚到哺乳動物都有類似結(jié)構(gòu)的分子[8]。目前對SARM的功能研究發(fā)現(xiàn),SARM是TLR信號通路中依賴 TRIF (TIR domain-containing adaptor inducing IFN- β , TRIF)的負性調(diào)控蛋白,在天然免疫應(yīng)答和炎癥發(fā)應(yīng)中發(fā)揮重要作用[9-11];同時,有研究發(fā)現(xiàn),SARM在壓力條件下能促進小鼠神經(jīng)元細胞凋亡[12]。但是目前尚無關(guān)于SARM在腫瘤發(fā)生、發(fā)展作用的研究報道,對SARM在腎細胞癌中的表達水平、是否參與調(diào)控腎細胞癌的發(fā)生、發(fā)展及其分子機制目前仍尚不清楚。因此對SARM在腎癌細胞中的功能及其分子機制的研究將是非常有意義的工作,其研究結(jié)果將為腎癌的分子靶向治療提供新的靶點。研究目的本研究將通過體外體內(nèi)實驗,以腎癌細胞株、BALB/C-nu裸鼠移植瘤和腎癌臨床組織標本為研究模型,檢驗SARM在腎癌組織和腎癌細胞株與癌旁正常腎組織和腎小管上皮細胞的表達水平有無差異,探討SARM在腎癌細胞的生長的作用功能、誘導細胞自噬發(fā)生的作用,同時觀察分子靶向藥物舒尼替尼與SARM的相互作用,并從分子水平初步探討SARM調(diào)控腎癌細胞生長的可能機制。以期明確SARM對腎癌細胞的生長的調(diào)控作用及其可能分子機制,為腎癌的分子靶向治療藥物的研究提供新的靶點和新的思路。研究方法一、臨床標本和細胞株研究:提取腎透明細胞癌組織和癌旁正常腎組織、正常腎小管上皮細胞(HK-2)和腎癌細胞株(786-O、OS-RC-2)的蛋白和RNA,利用免疫印跡法和半定量PCR技術(shù)觀察SARM在正常腎組織和細胞與腎透明細胞癌組織和細胞中的蛋白水平和RNA表達水平的差異。二、體外實驗研究:本研究采用細胞轉(zhuǎn)染和慢病毒包裝感染方法構(gòu)建了786-O和OS-RC-2穩(wěn)定表達SARM的腎癌細胞株,通過細胞計數(shù)法、平板克隆形成實驗檢測了穩(wěn)定表達SARM對腎癌細胞生長和增殖的影響;采用PI染色和Annexin V-PE/7AAD雙染色、利用流式細胞儀觀察穩(wěn)定表達SARM對腎癌細胞周期進行和細胞凋亡的影響;應(yīng)用分子靶向藥物舒尼替尼處理腎癌細胞,觀察分子靶向藥物與SARM的相互作用;采用無血清饑餓方法誘導穩(wěn)定表達SARM腎癌細胞發(fā)生自噬,探討SARM與自噬的關(guān)系。三、體內(nèi)試驗研究:通過OS-RC-2穩(wěn)定表達SARM腎癌細胞構(gòu)建腎癌BALB/C-nu裸鼠移植瘤模型,檢測穩(wěn)定表達SARM后對腎癌裸鼠移植瘤生長曲線及荷瘤體積有無影響。四、分子機制的初步探討:利用免疫印跡法研究穩(wěn)定表達SARM對PI3K/Akt/mTOR信號通路及ERK/MAPK信號通路影響,探討穩(wěn)定表達SARM對腎癌細胞生長、增殖、周期進行、凋亡的調(diào)控及誘導腎癌細胞自噬發(fā)生的可能分子機制。五、統(tǒng)計學方法:每組實驗均重復三次,用平均數(shù)土標準差進行統(tǒng)計學描述,根據(jù)實驗設(shè)計分別采用兩獨立樣本t檢驗(Independent sample t test)、重復測量數(shù)據(jù)的方差分析、析因設(shè)計資料的方差分析進行組間差異比較。實驗數(shù)據(jù)采用IBM SPSS19.0軟件進行上述統(tǒng)計學分析,P 0.05則表示為具有統(tǒng)計學意義。研究結(jié)果一、SARM在腎透明細胞癌組織蛋白表達水平降低腎透明細胞癌組織和腎癌細胞株中SARM的RNA水、平較癌旁正常腎組織和腎小管上皮細胞顯著升高,但是在蛋白表達水平上較癌旁正常腎組織和細胞株顯著減少,采用蛋白酶體抑制劑MG132抑制泛素發(fā)生后,SARM的蛋白水平明顯升高,說明SARM在從RNA翻譯到蛋白合成可能由于發(fā)生泛素化修飾,導致其在蛋白水平表達低下。二、成功構(gòu)建穩(wěn)定表達SARM細胞株通過X-tremeGENE HP DNA Transfection Reagen轉(zhuǎn)染和慢病毒包裝感染方法、流式細胞儀分選單克隆細胞成功構(gòu)建了穩(wěn)定表達SARM的786-0和OS-RC-2的細胞株,免疫印跡法對GFP-SARM蛋白表達水平進行驗證。三、穩(wěn)定表達SARM抑制了腎癌細胞的生長和增殖細胞計數(shù)法結(jié)果顯示,與GFP對照組相比,穩(wěn)定表達SARM后顯著抑制了腎癌細胞的生長(P0.05),同時平板克隆形成實驗結(jié)果發(fā)現(xiàn)穩(wěn)定表達SARM對腎癌細胞的增殖有顯著抑制作用(P0.05)。四、穩(wěn)定表達SARM阻滯細胞周期進行和促進細胞死亡流式細胞儀檢測發(fā)現(xiàn),與GFP對照組相比,穩(wěn)定表達SARM能夠阻滯腎癌細胞從G1期進入S期,同時穩(wěn)定表達SARM的腎癌細胞凋亡增多,說明SARM能阻滯細胞周期的進行、促進腎癌細胞死亡(P0.05)。五、SARM可促進舒尼替尼誘導腎癌細胞發(fā)生自噬免疫印跡法檢測發(fā)現(xiàn)舒尼替尼可以增強SARM在腎癌細胞株的表達水平和誘導腎癌細胞自噬發(fā)生。穩(wěn)定表達SARM可以促進腎癌細胞發(fā)生自噬,抑制SARM后可減弱舒尼替尼誘導腎癌細胞自噬發(fā)生,說明SARM在調(diào)控舒尼替尼誘導腎癌細胞自噬的發(fā)生中發(fā)揮重要作用。六、穩(wěn)定表達SARM可抑制腎癌裸鼠移植瘤的生長將穩(wěn)定表達SARM的OS-RC-2細胞株接種于4周齡的雌性BALB/C-nu裸鼠皮下,觀察裸鼠移植瘤生長曲線,荷瘤生長21天后處死裸鼠收獲荷瘤,發(fā)現(xiàn)穩(wěn)定表達SARM抑制了裸鼠移植瘤的生長,其瘤塊體積較GFP對照組顯著減小(P0.05)。七、穩(wěn)定表達SARM誘導腎癌細胞發(fā)生自噬通過無血清饑餓法誘導穩(wěn)定表達SARM細胞株發(fā)生自噬,免疫印跡法檢測LC-3和p62蛋白表達水平。與對照組相比,穩(wěn)定表達SARM后LC-3蛋白表達水平顯著升高,p62蛋白表達顯著降低。相反,干擾SARM后,LC-3蛋白水平顯著降低。說明SARM能誘導腎癌細胞發(fā)生自噬。八、穩(wěn)定表達SARM抑制腎癌細胞PI3K/Akt/mTOR信號通路免疫印跡法檢測發(fā)現(xiàn),穩(wěn)定表達SARM后,Akt、mTOR和p70S6K的磷酸化水平降低,說明穩(wěn)定表達SARM能抑制PI3K/Akt/mTOR信號通路。九、穩(wěn)定表達SARM抑制ERK信號通路免疫印跡法檢測發(fā)現(xiàn)穩(wěn)定表達SARM后,與對照組相比,磷酸化ERK1/2的表達水平顯著降低,表明穩(wěn)定表達SARM能抑制ERK信號通路。結(jié)論本研究首次研究SARM在腫瘤組織和細胞中的表達水平,首次研究并發(fā)現(xiàn)SARM對腎癌細胞生長的抑制作用及SARM可誘導腎癌細胞發(fā)生自噬,并初步探討了 SARM調(diào)控腎癌生長和誘導腎癌細胞發(fā)生自噬的初步分子機制:SARM可能通過抑制P13K/Akt/mTOR信號通路和抑制ERK信號通路參與調(diào)控腎細胞癌的生長,SARM誘導的腎細胞癌細胞的自噬可能通過PI3K/Akt/mTOR信號通路。同時發(fā)現(xiàn)SARM可能是多靶點酪氨酸激酶抑制劑舒尼替尼的作用靶點,SARM參與調(diào)控舒尼替尼誘導腎癌細胞的自噬。SARM可作為腎癌分子靶向治療的一個新的靶點,為腎癌分子靶向治療研究提供了一個新的靶點和新的思路。
[Abstract]:Renal cell carcinoma (RCC) is a malignant tumor originating from renal tubular epithelium, accounting for 80% - 90% of renal malignancies. It is one of the common malignant tumors in adult urinary system. About 1/3 of the patients with RCC had metastasis at the time of their first visit and were unable to undergo radical surgery. About 1/3 of the patients with localized RCC still had distant metastasis after radical surgery. For localized RCC patients, radical nephrectomy or nephron-sparing surgery was performed, and about 90% of them had distant metastasis. At the same time, metastatic renal cell carcinoma (mRCC) is insensitive to conventional radiotherapy and chemotherapy, and its 5-year survival rate is less than 10%[4]. In recent years, molecular targeted drug therapy has become a hotspot in tumor therapy, and has made great progress in the treatment of many kinds of tumors. It has become an important part of anti-tumor therapy [5]. Hypoxia-inducible factor (HIF), vascular endothelial growth factor (VEGF) and platelet-derived growth factor (p) have been found in the study. Latlet-derived growth factor (PDGF), epidermal growth factor (EGF) and its receptor (EGFR), mammalian target of rapamycin (mTOR) are all important target molecules for molecular targeted therapy. Abnormal expression of these molecules and the prognosis of renal cell carcinoma, especially clear cell renal cell carcinoma (RCC) are important. The most important molecular signaling pathways in RCC molecular targeted therapy include VEGF pathway and mTOR pathway. Vascular density in tumor tissues was significantly higher than that in normal kidney tissues [6,7]. Vascular growth factor binding to its receptor activates intracellular signal transduction pathways, including PI3K/Akt/mTOR and Ras/Raf/mitogen-activated protein kinase (MAPKK)/extracellular signal-regulated kinase (extrace). Llular signal regulated kinase (ERK) and other signaling pathways promote the proliferation and differentiation of endothelial cells, and thus participate in the growth, proliferation and differentiation of renal cell carcinoma. SARM (Sterile-alpha and HEAT/Armadillo motif containing protein) is a TLR (Toll-like receptor) signaling pathway containing TIR (Toll/interleukin-l receptor) structure. One of the five adaptor proteins of the TLR domain, which is evolutionarily conserved, has similar structure molecules from nematodes, fruit flies, amphioxus to mammals [8]. Answer and inflammatory response play an important role [9-11]; at the same time, some studies have found that SARM can promote the apoptosis of neurons in mice under pressure [12]. However, there are no reports about the role of SARM in tumorigenesis and development. The molecular mechanism of SARM in renal cell carcinoma is still unclear. Therefore, it is very meaningful to study the function and molecular mechanism of SARM in renal cell carcinoma. The results will provide a new target for molecular targeted therapy of renal cell carcinoma. To study the expression of SARM in renal cell carcinoma tissue and renal cell line, normal renal tissue and renal tubular epithelial cells adjacent to cancer, and to explore the role of SARM in the growth of renal cell carcinoma cells and the role of inducing autophagy, and to observe the interaction of molecular targeted drug sunitinib with SARM. In order to clarify the regulation of SARM on the growth of renal cell carcinoma and its possible molecular mechanism, and to provide new targets and new ideas for the research of molecular targeted therapy drugs for renal cell carcinoma. Protein and RNA expression in normal renal tissues and adjacent normal renal tissues, normal renal tubular epithelial cells (HK-2) and renal carcinoma cell lines (786-O, OS-RC-2) were detected by immunoblotting and semi-quantitative PCR. 2. In vitro Experimental study: In this study, 786-O and OS-RC-2 renal cell lines stably expressing SARM were constructed by cell transfection and lentiviral package infection. The effects of stably expressing SARM on the growth and proliferation of renal cell carcinoma cells were detected by cell counting and plate cloning assay. PI staining and Annexin V-PE/7AAD double staining were used, and flow cytometry was used. The effects of stable expression of SARM on cell cycle progression and apoptosis of renal cell carcinoma cells were observed. Molecular targeting drug sunitinib was used to treat renal cell carcinoma cells and the interaction between molecular targeting drugs and SARM was observed. Serum-free starvation was used to induce autophagy of renal cell carcinoma cells stably expressing SARM, and the relationship between SARM and autophagy was discussed. Study: The BALB/C-nu nude mice model of renal cell carcinoma was established by OS-RC-2 stably expressing SARM cells. The effects of stable expression of SARM on the growth curve and tumor-bearing volume of transplanted renal cell carcinoma in nude mice were detected. Fourthly, the preliminary study of molecular mechanism: The PI3K/Akt/mTOR signaling pathway and ERK/MAPK signaling were studied by Western blot. To explore the possible molecular mechanism of stably expressing SARM on the growth, proliferation, cycle progression, apoptosis regulation and autophagy of renal cell carcinoma. 5. Statistical methods: Each group of experiments were repeated three times, and were statistically described by mean soil standard deviation. According to the experimental design, two independent sample t test was used (In The experimental data were analyzed by IBM SPSS 19.0 software, and P 0.05 was statistically significant. Results 1. The expression of SARM protein in clear cell carcinoma of kidney decreased renal dialysis. The level of SARM protein in clear cell carcinoma and renal cell lines was significantly higher than that in normal renal tissues and renal tubular epithelial cells, but the level of protein expression was significantly lower than that in normal renal tissues and renal tubular epithelial cells. NA translation to protein synthesis may be due to ubiquitination modification, resulting in its low expression at protein level. 2. A stable expression of SARM cell line was successfully constructed by X-tremeGENE HP DNA Transfection Reagen transfection and lentiviral packaging infection. Flow cytometry sorted monoclonal cells successfully constructed 786-0 and OS-RC stably expressing SARM. The expression level of GFP-SARM protein was verified by Western blot. 3. The stable expression of SARM inhibited the growth and proliferation of renal cell carcinoma cells. Compared with the GFP control group, the stable expression of SARM significantly inhibited the growth of renal cell carcinoma cells (P 0.05). At the same time, the results of plate cloning showed stable expression of S. ARM significantly inhibited the proliferation of renal cell carcinoma cells (P 0.05). 4. Steady expression of SARM inhibited cell cycle and promoted cell death. Compared with GFP control group, stable expression of SARM inhibited the progression of renal cell carcinoma cells from G1 phase to S phase, and increased apoptosis of renal cell carcinoma cells stably expressing SARM, suggesting that SARM could block the apoptosis of renal cell carcinoma cells. Cell cycle progression, promote renal cell death (P 0.05). Fifthly, SARM can promote sunitinib-induced renal cell autophagy Western blot assay found that sunitinib can enhance the expression of SARM in renal cell lines and induce renal cell autophagy. Stable expression of SARM can promote renal cell autophagy, inhibit SARM. SARM plays an important role in the regulation of Sunitinib-induced autophagy. 6. Stable expression of SARM can inhibit the growth of renal cell carcinoma xenografts in nude mice. OS-RC-2 cell line stably expressing SARM was inoculated subcutaneously in 4-week-old female BALB/C-nu mice to observe the effect of SARM on the autophagy. The growth curve of transplanted tumor was observed. The stable expression of SARM inhibited the growth of transplanted tumor in nude mice, and the tumor volume was significantly smaller than that of GFP control group (P 0.05). 7. The stable expression of SARM induced autophagy of renal cancer cells. The stable expression of SARM induced autophagy of renal cancer cells by serum-free starvation induced stable expression of SARM cell lines. The expression of LC-3 and p62 protein was detected by Western blot. Compared with the control group, the expression of LC-3 protein was significantly increased and that of p62 protein was significantly decreased after stably expressing SARM. On the contrary, the expression of LC-3 protein was significantly decreased after interfering with SARM. The phosphorylation levels of Akt, mTOR and p70S6K decreased after stably expressing SARM, indicating that stably expressing SARM could inhibit PI3K/Akt/mTOR signaling pathway. Ninth, stably expressing SARM inhibiting ERK signaling pathway was detected by immunoblotting. After stably expressing SARM, the phosphorylated ERK1/2 expression level was significantly lower than that of the control group. Conclusion This study is the first to study the expression level of SARM in tumor tissues and cells. It is the first to find that SARM can inhibit the growth of renal cell carcinoma cells and induce autophagy of renal cell carcinoma cells. Initial Molecular Mechanisms: SARM may be involved in regulating the growth of renal cell carcinoma by inhibiting P13K/Akt/mTOR signaling pathway and ERK signaling pathway. SARM-induced autophagy of renal cell carcinoma cells may be mediated by PI3K/Akt/mTOR signaling pathway. SARM may be the target of Sunitinib, a multi-target tyrosine kinase inhibitor. SARM can be used as a new target for molecular targeted therapy of renal cell carcinoma, which provides a new target and a new idea for molecular targeted therapy of renal cell carcinoma.
