技術(shù)領(lǐng)域:
本發(fā)明涉及一種新的人類河豚毒素耐受性鈉離子通道和相關(guān)的核苷酸,以及對可用于治療急性或慢性疼痛或其它興奮性過高狀態(tài)的試劑進(jìn)行鑒定的篩選試驗(yàn)。此申請相關(guān)于1998年1月29日提交的美國臨時(shí)申請60/072,990;1998年11月20日提交的美國臨時(shí)申請60/109,402;1998年11月20日提交的美國臨時(shí)申請60/109,666;1999年1月29日提交的PCT國際申請PCT/US99/02008,和1999年7月16日提交的美國專利申請09/354,147,在此將其全部引入作為參考。
背景A.鈉通道電壓門控鈉通道是一類特化的蛋白分子,它們作為分子電池允許可興奮性細(xì)胞(神經(jīng)元和肌纖維)產(chǎn)生和傳播電沖動。大鼠腦內(nèi)的電壓門控Na+通道由三個(gè)亞單位組成,形成孔的a亞單位(260KDa)和兩個(gè)能調(diào)節(jié)a亞單位的特性的輔助亞單位b1(36KDa)和b2(33KDa);a亞單位足以形成能產(chǎn)生鈉離子跨膜流動的功能性通道(Catterall,(1993)神經(jīng)科學(xué)趨勢(TrendsNeurosci).16,500-506;Isom等,(1994)神經(jīng)元12,1183-1194)。在脊椎動物中已經(jīng)鑒定出九種不同的a亞單位并且它們由一個(gè)擴(kuò)展基因家族的成員編碼(Goldin(1995)受體和通道手冊(North,主編)CRC出版;Akopian等,(1996)自然379,257-262;Akopian等,(1997)FEBS Lett.400,183-187;Sangameswaran等,(1996)生物學(xué)和化學(xué)雜志271,5953-5956),這些基因中多個(gè)已克隆出在多種哺乳動物物種包括人類中相應(yīng)的直向同源基因(orthologue)。特異性a亞單位以組織特異性和發(fā)育特異性方式表達(dá)(Beckh等,(1998)歐洲分子生物學(xué)組織雜志8,3611-3616;Mandel,(1992)膜生物學(xué)雜志125,193-205)。電壓門控鈉通道a亞單位在人或動物的多種疾病中表達(dá)模式異?;虬l(fā)生突變(Roden和George,(1997)美國生理學(xué)雜志273,H511-H525;Ptacek,(1997)神經(jīng)肌肉功能異常(Neuromuscul.Disord.)7,250-255;Cannon,(1997)神經(jīng)肌肉功能異常7,241-249;Cannon,(1996)神經(jīng)科學(xué)趨勢19,3-10);Rizzo等,(1996)歐洲神經(jīng)病學(xué)36,3-12)。
電壓門控鈉通道a亞單位由具有不同內(nèi)在同源性但有相似的預(yù)測結(jié)構(gòu)的四個(gè)結(jié)構(gòu)域(D1-4)組成,它們由三個(gè)胞內(nèi)環(huán)(L1-3)連接。這四個(gè)結(jié)構(gòu)域折疊后形成一個(gè)通道,它經(jīng)小孔通向細(xì)胞質(zhì)和細(xì)胞外空間??赘鶕?jù)細(xì)胞膜的生理狀態(tài)而開放和關(guān)閉。
每個(gè)結(jié)構(gòu)域由六個(gè)允許該蛋白跨膜與細(xì)胞內(nèi)和細(xì)胞外接頭交織的跨膜部分(S1-6)組成。四個(gè)結(jié)構(gòu)域中S5-S6部分的接頭包含使通道的孔排列整齊的序列,和起過濾作用以選擇性允許鈉離子橫穿該通道孔進(jìn)入細(xì)胞質(zhì)并因此產(chǎn)生離子流的高度保守型氨基酸亞群。四個(gè)結(jié)構(gòu)域中各自的兩性S4片段富含每三個(gè)氨基酸即重復(fù)一次的堿性殘基,這種S4片段起電壓感受器的作用并因跨膜電壓差的變化而發(fā)生構(gòu)象改變。這反過來觸發(fā)所述蛋白的構(gòu)象改變,從而使其孔向細(xì)胞外鈉離子梯度開放。
在多數(shù)已知的電壓門控鈉通道a亞單位中,在通道開放(激活)后幾毫秒內(nèi)通道迅速關(guān)閉和變成不能打開的狀態(tài)(失活);另一方面,SNS型通道緩慢失活并且需要更大的電壓變化才激活。L3,連接結(jié)構(gòu)域D3和D4的環(huán),包含一個(gè)三肽,該三肽起到細(xì)胞內(nèi)探頭的作用,能在激活后使孔關(guān)閉,并因此誘導(dǎo)通道進(jìn)入失活狀態(tài)。失活后,這些通道進(jìn)一步發(fā)生構(gòu)象變化以恢復(fù)到它們的靜息狀態(tài)并重新等待激活。該階段稱為從失活中恢復(fù)(再啟動(repriming))。不同的通道以不同的速率再啟動,SNS中的再啟動相對較快。
根據(jù)氨基酸相似性,電壓門控鈉通道家族進(jìn)一步分成兩個(gè)亞家族(Felipe等,(1994)生物學(xué)和化學(xué)雜志269,30125-30131)。已克隆的九種通道中有八種屬于亞家族1,它們有許多共同結(jié)構(gòu)特征,尤其是它們的S4跨膜部分。但是,已經(jīng)發(fā)現(xiàn)其中某些具有不同的失活和再啟動動力學(xué)特性。亞家族2僅一種通道,也稱作非典型通道,已經(jīng)在人類、大鼠和小鼠組織中鑒定出。這個(gè)亞家族基本特征是其S4部分中堿性殘基數(shù)目減少,因而預(yù)計(jì)其與亞家族1具有不同的電壓依從性。因?yàn)閬喖易?通道的電生理學(xué)特性尚未闡明故其生理功能目前尚不清楚。
通過一種神經(jīng)毒素,河豚毒素對電壓門控鈉通道的阻斷已經(jīng)把這些通道功能性分類為敏感性(TTX-S)和抵抗性(TTX-R)表型。至今已鑒定出兩種哺乳類TTX-R通道,一種是對心肌和中樞神經(jīng)系統(tǒng)(CNS)非常局限區(qū)域具有特異性,第二種,SNS,局限于背根神經(jīng)節(jié)和三叉神經(jīng)節(jié)的外周神經(jīng)元(PNS)。賦予對TTX抵抗性或敏感性的特異氨基酸殘基位于通道孔的離子選擇性過濾網(wǎng)中。SNS通道在國際專利申請WO97/01577中也有描述。
B.疾病狀態(tài)下鈉通道的作用因?yàn)椴煌腘a+通道同型a亞單位顯示出不同的動力學(xué)和電壓依從性,所以可興奮細(xì)胞的興奮特性依賴于所表達(dá)的通道類型的精確混合。已經(jīng)證明心肌和骨骼肌a亞單位的突變體引起多種肌肉異常。例如骨骼肌通道的S4中僅一個(gè)堿性氨基酸殘基改變就足以改變此通道的動力學(xué)特性并且在許多患者中誘導(dǎo)疾病狀態(tài)。心臟通道L3的一個(gè)三肽缺失,近乎使通道失活,導(dǎo)致稱作長QT綜合癥的心臟異常。在與通道孔排成一列的Scn8a結(jié)構(gòu)域1的S5-S6連接中僅一個(gè)氨基酸改變,就引起小鼠突變型“搖擺”。經(jīng)另外的突變使此通道完全丟失導(dǎo)致小鼠運(yùn)動終板“med”病。此突變的特征是運(yùn)動神經(jīng)元對受神經(jīng)支配的肌肉的刺激缺失。
C.鈉通道和疼痛軸突損傷(神經(jīng)纖維,也叫軸突的損傷)可以產(chǎn)生慢性痛(術(shù)語稱神經(jīng)病疼痛)。大量研究已證明軸突損傷后神經(jīng)元胞體和樹突的興奮性改變了(Eccles等,(1958)生理學(xué)雜志14311-40;Gallego等,(1987)生理學(xué)雜志(Lond)391,39-56;Kuno和Llinas,(1970)生理學(xué)雜志(Lond)210,807-821),并且有證據(jù)表明軸突損傷后神經(jīng)元胞體和樹突的鈉通道密度改變(Dodge和Cooley,(1973)IBM J.Res.Dev.17,219-229;Titmus和Faber(1986)神經(jīng)生理學(xué)雜志55,1440-1454;Sernagor等,(1986)美國國家科學(xué)院院報(bào)83,7966-7970)。在神經(jīng)元上鈉通道不同類型的異?;旌媳磉_(dá)也可導(dǎo)致異常激活(Rizzo等,(1996)歐洲神經(jīng)病學(xué)36,3-12),也可形成興奮性過高,感覺異?;蛱弁础?br>
最近對大鼠DRG感覺神經(jīng)元的研究已經(jīng)證明在各種損害后TTX-R和TTX-S離子流的表達(dá)圖譜和在DRG神經(jīng)元中編碼能產(chǎn)生這些離子流的通道的許多mRNA轉(zhuǎn)錄有很大改變(Rizzo等,(1995)Neurobiol.Dis.287-96;Cummins等,(1997)神經(jīng)生理學(xué)雜志17,3503-3514;Dib-Hajj等,(1996)美國國家科學(xué)院院報(bào)93,14950-14954)。例如,已顯示軸突切開術(shù)(axotomy)后在已鑒定的皮膚感覺傳入神經(jīng)元上TTX-R流緩慢失活的減弱和同時(shí)TTX-S Na+流快速失活的增強(qiáng)(Rizzo等,(1995)Neurobiol.Dis.287-96)。也有報(bào)道軸突切開術(shù)后TTX-S的丟失,緩慢再啟動離子流和TTX-R離子流以及在TTX-S上的增加,在痛覺(疼痛)神經(jīng)元上的快速再啟動離子流(Cummins和Waxman(1997)神經(jīng)生理學(xué)雜志17,3503-3514),SNS轉(zhuǎn)錄子的下調(diào)和α-III轉(zhuǎn)錄子的同時(shí)上調(diào)(Dib-Hajj等,(1996)美國國家科學(xué)院院報(bào)93,14950-14954)。另外與軸突切開術(shù)相關(guān)的是aI和aII mRNA水平的中度升高(Waxman等,(1994)神經(jīng)生理學(xué)雜志72,466-470)。鈉通道特性的這些改變看來促成異常激活,其構(gòu)成軸突損傷后患者遭受神經(jīng)病疼痛的基礎(chǔ)。
和疼痛也有關(guān)系的炎癥(術(shù)語稱為炎性痛),也會引起痛覺DRG神經(jīng)元上鈉流特性改變。在培養(yǎng)的小C型痛覺DRG神經(jīng)元上炎性調(diào)節(jié)物上調(diào)TTX-R離子流(Gold等,(1996)美國國家科學(xué)院院報(bào)93,1108-1112;England等,(1996)生理學(xué)雜志495,429-440)。這些調(diào)節(jié)物的快速作用提示其作用包括對現(xiàn)有TTX-R通道的翻譯后修飾?,F(xiàn)已斷定在C型DRG神經(jīng)元上炎癥也增加TTX-R Na+流并且上調(diào)SNS轉(zhuǎn)錄子(Tanaka等,(1998)Neuroreport.9,967-972)。這些數(shù)據(jù)表明Na+流特性的改變在炎癥引起的疼痛中有作用。
D.慢性痛的治療許多類藥物(抗驚厥藥如苯妥英和酰胺咪嗪(carbamazepine);抗心律失常藥如mexitine;局麻藥如利多卡因)作用于鈉通道上。因?yàn)楦鞣N鈉通道產(chǎn)生的鈉流具有不同特性,所以預(yù)期對特異通道亞型的選擇性阻斷或激活(或其它調(diào)節(jié))會有重要治療價(jià)值。而且,在特異類型神經(jīng)元上某種同型a亞單位(PNl,SNS,NaN)的選擇性表達(dá)提供了選擇性改變其行為的方法。
DRG痛覺神經(jīng)元是PNS TTX-R Na+流的主要來源。因此,產(chǎn)生TTX-R離子流的Na+通道為操縱產(chǎn)痛覺的神經(jīng)元提供了相對特異性的靶目標(biāo)。在這些DRG神經(jīng)元中一種TTX-R通道,SNS的分子結(jié)構(gòu)已經(jīng)測定出來,但是在我們的研究之前,尚未斷定這些神經(jīng)元中是否有其它TTX-R通道。如果這些通道能被鑒定,它們將是優(yōu)先在痛覺神經(jīng)元上表達(dá)并且其調(diào)節(jié)作用會減弱痛覺傳遞的理想的靶分子候選者。

發(fā)明詳述本發(fā)明涉及申請人發(fā)現(xiàn)的稱作NaN的新基因。NaN編碼一種以前未鑒定的蛋白,在此稱作NaN,它屬于電壓門控鈉通道蛋白家族a亞單位并可產(chǎn)生TTX-R鈉流。在象神經(jīng)元和肌纖維這樣的可興奮細(xì)胞上這些通道構(gòu)成沖動產(chǎn)生和傳播的基礎(chǔ)。NaN是與其它先前已經(jīng)鑒定的通道有不同序列的新的鈉通道。NaN優(yōu)先在感覺神經(jīng)元而不是其它神經(jīng)元上表達(dá),這使其成為在急性和/或慢性痛病理相關(guān)的診斷和/或治療中非常有用的靶點(diǎn)。
A.定義本說明書使用的一些技術(shù)術(shù)語和短語意指下列含義短語“調(diào)節(jié)”或“改變”指上調(diào)或下調(diào)特定受體,配體或離子流的水平或活性。例如試劑可以通過抑制(降低)或增強(qiáng)(升高)鈉流來調(diào)節(jié)Na+流。同樣,試劑可以調(diào)節(jié)NaN鈉通道的表達(dá)水平或已表達(dá)的NaN通道的活性。
短語“鈉流”或“Na+流”指鈉離子的跨細(xì)胞膜流動,其經(jīng)常穿過能特異性通透某種離子(這里指鈉離子)的通道(特化的蛋白分子)而流動。
短語“電壓門控(voltage gated)”意思是細(xì)胞膜在特定電壓范圍時(shí)離子通道開放。在膜去極化時(shí)電壓敏感型鈉通道開放。然后其允許Na+離子流入細(xì)胞,產(chǎn)生進(jìn)一步去極化。這允許細(xì)胞產(chǎn)生電沖動(也稱作動作電位)。
短語“快速再啟動”意思是離子流從失活狀態(tài)再啟動的速度比在電壓門控鈉通道家族的眾多其它成員上更快。
短語“TTX-R”和“TTX-S”意思分別是指穿過細(xì)胞膜的離子流對濃度約100nM的河豚毒素(某些生物產(chǎn)生的一種神經(jīng)毒素)抵抗或敏感。
短語“外周神經(jīng)系統(tǒng)(PNS)”指神經(jīng)系統(tǒng)中在腦和脊髓以外的部分,即脊髓根部及其相關(guān)神經(jīng)節(jié)如背根神經(jīng)節(jié)(DRG)和三叉神經(jīng)節(jié),以及外周神經(jīng)。
短語“抑制Na+流流動”意思是相對于未暴露給所述試劑的對照細(xì)胞該試劑降低了所述離子流流動。優(yōu)選的抑制劑會選擇性抑制所述離子流流動,而不影響其它鈉通道的離子流流動;或者它抑制目的通道的鈉流程度遠(yuǎn)大于其它鈉通道。
短語“增強(qiáng)Na+流流動”意思是相對于未暴露給該試劑的對照細(xì)胞,該試劑降低了所述離子流流動。優(yōu)選的制劑會選擇性增強(qiáng)所述離子流流動,而不影響其它鈉通道的離子流流動;或者它增強(qiáng)目的通道的Na+流程度遠(yuǎn)大于其它鈉通道。
短語“特異性雜交”指核酸在高嚴(yán)謹(jǐn)或中度嚴(yán)謹(jǐn)條件下與編碼NaN鈉通道的核酸,如SEQ ID NO1,4,6,或41的DNA序列雜交。
短語“分離的核酸”指已經(jīng)從編碼其它多肽的雜質(zhì)核酸中分離出或基本純化出的核酸?!昂怂帷敝杆行问降腄NA和RNA,包括cDNA分子和反義RNA分子。
短語“RT-PCR”指用逆轉(zhuǎn)錄酶逆轉(zhuǎn)錄(RT)RNA,隨后用聚合酶鏈?zhǔn)椒磻?yīng)(PCR)擴(kuò)增特定cDNA模板的過程;PCR需要通用引物或基因特異性引物以及耐熱的DNA聚合酶,例如,Taq DNA聚合酶。
短語“優(yōu)先表達(dá)”意思是電壓門控Na+通道在指定組織中的表達(dá)量比在其它組織中的高,且這種差異是可檢測的。例如,發(fā)現(xiàn)在背根神經(jīng)節(jié)或三叉神經(jīng)節(jié)優(yōu)先表達(dá)的電壓門控Na+通道比其它組織或細(xì)胞類型中的表達(dá)量大,并可檢測到這種差異。電壓門控Na+通道的數(shù)目可以用任何已知手段檢測,包括檢測特異RNA水平和用特異抗體檢測通道蛋白。
B.NaN鈉通道的定性本發(fā)明涉及以前未鑒定的,電壓門控鈉通道a亞單位(NaN),預(yù)測是TTX-R,為電壓門控型,并優(yōu)先在支配軀體的感覺神經(jīng)元(背根神經(jīng)節(jié)或DRG)上和面部(三叉神經(jīng)節(jié))上表達(dá)。預(yù)測的開放讀碼框架(ORF)即NaN蛋白分子的編碼序列部分,已經(jīng)用圖2(SEQ ID NO3),圖7B(SEQ ID NO5),圖8B(SEQ ID NO8)或圖11B(SEQ ID NO42)代表的源自不同種屬(大鼠,小鼠,人類)的假定氨基酸序列確定。
電壓門控鈉通道的所有有關(guān)的明顯標(biāo)志序列存在于NaN的預(yù)測位置,說明NaN屬于鈉通道家族。但是NaN不同于以往鑒定的所有其它鈉通道,與它們中每一種的序列同一性低于53%。NaN有別于SNS,這是直至我們的發(fā)明時(shí),在PNS唯一已經(jīng)鑒定的其它TTX-R鈉通道亞單位。我們在未使用以SNS為基礎(chǔ)或?qū)NS特異的引物或探針的情況下鑒定并克隆了NaN。而且,NaN和SNS在它們預(yù)測的開放讀碼框架(ORF)中僅有47%相似,類似于NaN與所有亞家族1成員的有限相似性。
與現(xiàn)有a亞單位的低序列相似性清楚證明NaN是新基因,而不僅是現(xiàn)有通道的變體。相對于其它電壓門控通道的序列變化提示NaN可能是新的且以前未鑒定過的,與SNS相比具有不同特性的第三類TTX-R通道原型。存在于痛覺DRG和三叉神經(jīng)元上的NaN和SNS可以以不同方式對藥理學(xué)干預(yù)產(chǎn)生應(yīng)答。NaN在感覺性DRG神經(jīng)元和三叉神經(jīng)元上的優(yōu)先表達(dá)為選擇性修飾這些神經(jīng)細(xì)胞的行為而不影響腦和脊髓中其它神經(jīng)細(xì)胞提供了靶點(diǎn)。NaN通道特性的進(jìn)一步闡明對更全面理解設(shè)計(jì)成調(diào)節(jié)“TTX-R”離子流功能的藥物的效應(yīng)將是非常重要的,這里的“TTX-R”離子流是有DRG痛覺神經(jīng)元的特征并且導(dǎo)致痛覺信息傳遞,以及對神經(jīng)損傷后和其它疼痛狀態(tài)時(shí)激活模式的異常。
C.NaN核酸本發(fā)明的核酸分子包括圖1,7A,8A和11A所示核苷酸序列以及編碼圖2,7B,8B和11B的氨基酸序列的核苷酸序列。本發(fā)明要求權(quán)利的核酸也包括與含有圖1,7A,8A和11A所示核苷酸序列或編碼圖2,7B,8B和11B中氨基酸序列的核苷酸序列的核酸特異性雜交的核酸。在高度或中度嚴(yán)謹(jǐn)條件下與包括所述序列的核酸特異性雜交的核酸仍穩(wěn)定結(jié)合于該核酸上。高度嚴(yán)謹(jǐn)和中度嚴(yán)謹(jǐn)條件是指那些普通定義的和可達(dá)到的,例如由以下定義的Sambrook等,(1989)分子克隆-實(shí)驗(yàn)指南,冷泉港出版社或者Ausubel等,(1995)分子生物學(xué)現(xiàn)代方法,Greene出版。嚴(yán)謹(jǐn)度的精確水平并不重要,重要的是應(yīng)選擇在特異性雜交發(fā)生時(shí)能提供清晰的可檢測信號的條件。
雜交是在眾多變量中序列同一性(同源性),序列的G+C含量,緩沖鹽含量,序列長度和解鏈溫度(T[m])的功能(見Maniatis等,(1982)分子克隆,冷泉港出版社)。在相似序列長度,緩沖鹽濃度和溫度時(shí),雜交技術(shù)可提供評價(jià)序列同一性(同源性)的有效變量。例如,當(dāng)至少有90%同源性時(shí),雜交通常在68℃的從20×SSC稀釋成6×SSC的緩沖液中進(jìn)行(見Sambrook等,(1989)分子克隆-實(shí)驗(yàn)指南,冷泉港出版社)。用于最終Southern印跡洗滌的緩沖鹽可以用低濃度,例如,0.1×SSC和較高溫度如68℃,而且兩序列將形成雜合雙鏈(雜交)。將上述雜交和洗滌條件一起使用被定義為高度嚴(yán)謹(jǐn)條件,當(dāng)兩序列有至少約80%同源性時(shí)使用中度嚴(yán)謹(jǐn)條件。即,用溫度約50-55℃的6×SSC進(jìn)行雜交。最后洗滌的鹽濃度約為1-3×SSC,溫度約為60-68℃。這樣的雜交和洗滌條件定義為中度嚴(yán)謹(jǐn)條件。
特別是,特異性雜交發(fā)生在兩種核酸分子間存在高度互補(bǔ)性的條件下。通過特異性雜交,互補(bǔ)性一般至少約70%,75%,80%,85%,優(yōu)選約90-100%,或最優(yōu)選約95-100%。當(dāng)涉及到SEQ ID NO41和42的人類NaN序列時(shí),優(yōu)選的同源序列一般編碼與SEQ ID NO42具有至少約81%氨基酸序列相似性或至少約75%或76%序列同一性的NaN蛋白。更優(yōu)選人類NaN序列第670位含有帶正電的氨基酸,優(yōu)選精氨酸。
本文中,同源性或同一性用適于序列相似性搜索的blastp,blastn,blastx,tblastn和tblastx程序中的算法(Karlin等,(1990)美國國家科學(xué)院院報(bào)87,2264-2268和Altschul,(1993)J.Mol.Evol.36,290-300,在此將兩者引入作參考)經(jīng)BLAST(Basic Local Alignment Search Tool)分析確定。BLAST程序使用的方法是首先考慮目標(biāo)序列與數(shù)據(jù)庫序列的相似片段,然后評價(jià)所鑒定的所有配對的統(tǒng)計(jì)學(xué)意義,最后總結(jié)出符合預(yù)定顯著性閾值的配對。對序列數(shù)據(jù)庫的相似性搜索中基本問題的討論見Altschul等,Nat.Genet.(1994)6,119-129,其引入作為參考。柱形圖(histogram),說明(descriptions),序列對比(alignments),預(yù)期值(expect)(即,能報(bào)告與數(shù)據(jù)庫序列匹配的統(tǒng)計(jì)學(xué)顯著性閾值),閾值(cutoff),矩陣(matrix)和篩選(filter)的搜索參數(shù)均使用默認(rèn)設(shè)置。lastp,blastx,tblastn和tblastx使用的默認(rèn)評分矩陣是BLOSUM62矩陣(Henikoff等,(1992)美國國家科學(xué)院院報(bào)89,10915-10919,在此引入以作參考)。對于blastn,用M(即一對匹配殘基的獎(jiǎng)勵(lì)分)對N(即不匹配殘基的罰分)的比率設(shè)置評分矩陣,其中M和N的默認(rèn)值分別是5和-4。
本發(fā)明的核酸可以按照本發(fā)明的許多方式使用。例如,它們可被用作核酸探針去篩選其它c(diǎn)DNA和基因組DNA文庫以便通過雜交選出編碼同源NaN序列的其它DNA序列。所述核酸探針可以是用放射性核苷酸或用非放射性方法(例如生物素)標(biāo)記的RNA或DNA。篩選可在各種嚴(yán)謹(jǐn)度(通過調(diào)整雜交Tm,通常是將離子強(qiáng)度、溫度和/或甲酰胺的有無進(jìn)行組合)下進(jìn)行以分離近親或遠(yuǎn)親同源物。核酸也可以用來產(chǎn)生引物以便用聚合酶鏈?zhǔn)椒磻?yīng)(PCR)技術(shù)擴(kuò)增cDNA或基因組DNA。本發(fā)明的核酸序列也可用來鑒定基因組中的鄰近序列,例如,NaN的側(cè)翼序列和調(diào)節(jié)元件。核酸也可用來產(chǎn)生能調(diào)節(jié)NaN基因表達(dá)水平的反義引物或構(gòu)建體。氨基酸序列可用來設(shè)計(jì)和產(chǎn)生對NaN特異的抗體,此抗體可用來定位特定細(xì)胞上的NaN和調(diào)節(jié)細(xì)胞表面表達(dá)的NaN通道的功能。
本發(fā)明的核酸還包括重組制備的NaN序列變體。例如,可制備具有本文公開的開放讀碼框的融合蛋白,或其功能片段,以及任何可獲得的融合蛋白。也可以制備編碼NaN嵌合蛋白的核酸分子,如含有分別來自不同物種的結(jié)構(gòu)域的嵌合蛋白。這種嵌合蛋白包括但不局限于含有小鼠或大鼠結(jié)構(gòu)域的人類NaN嵌合體,或含有人類結(jié)構(gòu)域的小鼠或大鼠嵌合體。優(yōu)選的嵌合體包括帶有圍繞在與人NaN第670位氨基酸相當(dāng)?shù)臍埢車拇笫蠡蛐∈蠼Y(jié)構(gòu)域的人類NaN。
D.載體和轉(zhuǎn)化的宿主細(xì)胞本發(fā)明也包括重組載體,其含有編碼NaN鈉通道的核酸并能在相容的宿主細(xì)胞中復(fù)制和指導(dǎo)所述核酸表達(dá)。例如,用如T4 DNA連接酶等酶將本發(fā)明DNA插入載體可按任何傳統(tǒng)的方式進(jìn)行。當(dāng)DNA和目的載體都用相同的限制性內(nèi)切酶切割時(shí)此插入容易完成,因?yàn)檫@樣產(chǎn)生了互補(bǔ)的DNA末端。如果此步未能完成,就必須修飾回復(fù)消化單鏈DNA所產(chǎn)生的切割末端以形成鈍性末端,或者通過用適當(dāng)?shù)腄NA聚合酶補(bǔ)齊該單鏈末端產(chǎn)生相同的結(jié)果。此時(shí),可進(jìn)行平端連接。或者,可通過在DNA末端連接核苷酸序列(接頭)產(chǎn)生想要的任何位點(diǎn)。這樣的接頭可以包含編碼限制性位點(diǎn)識別序列的特異寡核苷酸序列。
可以使用任何可得到的載體和合適的相容性宿主細(xì)胞(Sambrook等,(1989)分子克隆-實(shí)驗(yàn)指南,冷泉港出版社;Ausubel等,(1995)分子生物學(xué)現(xiàn)代方法,Greene出版)。市售載體,如New England Biolabs,Promega,Stratagene或其它市售載體均包括在內(nèi)。
用本發(fā)明的rDNA(重組DNA)分子轉(zhuǎn)化合適的細(xì)胞宿主可通過熟知方法完成,它們通常取決于所用載體的類型和宿主系統(tǒng)??蓪NA注射入蛙卵母細(xì)胞并使通道表達(dá),但一般情況下,優(yōu)選在哺乳動物細(xì)胞系(例如HEK293和CHO細(xì)胞)中表達(dá)。關(guān)于原核宿主細(xì)胞的轉(zhuǎn)化,常使用電穿孔和鹽處理方法(見,例如,Cohen等,(1972)美國國家科學(xué)院院報(bào)69,2110-2114;和Maneatis等,(1982)分子克隆-實(shí)驗(yàn)指南,冷泉港出版社)。關(guān)于用含rDNA的載體轉(zhuǎn)化脊椎動物細(xì)胞,一般使用電穿孔,陽離子脂質(zhì)體或鹽處理方法(Graham等,(1973)病毒學(xué)52,456-467;Wigler等,美國國家科學(xué)院院報(bào)(1979)76,1373-1376)。
成功轉(zhuǎn)化的細(xì)胞,即包含本發(fā)明rDNA分子的細(xì)胞,可用熟知的技術(shù)鑒定。例如,可將導(dǎo)入本發(fā)明rDNA后產(chǎn)生的細(xì)胞克隆以便產(chǎn)生單菌落。收獲這些菌落的細(xì)胞,裂解并且用傳統(tǒng)方法(Southern,(1975)分子生物學(xué)雜志98,503-517)檢測它們的DNA含量以確定rDNA的存在,或者用免疫學(xué)方法分析這些細(xì)胞產(chǎn)生的蛋白。如果在重組DNA的構(gòu)建中使用了諸如綠色熒光蛋白等標(biāo)記,也可通過細(xì)胞分類辨別這些分子的熒光,從而體內(nèi)檢測轉(zhuǎn)染的細(xì)胞。
在重組通道的短暫表達(dá)中,用于測量Na+流或細(xì)胞內(nèi)Na+水平的轉(zhuǎn)化細(xì)胞,通常使用鈣-磷酸鹽沉淀技術(shù)將構(gòu)建體與熒光報(bào)道質(zhì)粒(如pGreenLantern-1,Life Technologies)共轉(zhuǎn)染至細(xì)胞如HEK293細(xì)胞中而制備(Ukomadu等,(1992)神經(jīng)元8,663-676)。HEK293細(xì)胞一般生長于添加了10%胎牛血清(Life Technologies)的高葡萄糖DMEM(Life Technologies)上。48小時(shí)后,挑選帶綠色熒光的細(xì)胞進(jìn)行記錄(Dib-Hajj等,(1997)FEBSLett.416,11-14)。
為制備連續(xù)表達(dá)重組通道的細(xì)胞系,將NaN構(gòu)建體克隆到哺乳動物細(xì)胞中帶有選擇標(biāo)記的其它載體上。用鈣磷酸鹽沉淀技術(shù)進(jìn)行轉(zhuǎn)染(Ukomadu等,(1992)神經(jīng)元8,663-676)。將人胚腎(HEK-293),中國倉鼠卵巢(CHO)細(xì)胞,它們的衍生物或其它合適的細(xì)胞系在標(biāo)準(zhǔn)組織培養(yǎng)條件下于加有10%胎牛血清的DMEM培養(yǎng)基上培養(yǎng)。將鈣磷酸鹽-DNA混合物加入細(xì)胞培養(yǎng)基中并放置15-20小時(shí),之后將細(xì)胞用新鮮培養(yǎng)基洗滌。48小時(shí)后,加入抗生素(G418),從而選出已獲得新霉素抗性的細(xì)胞。在G418中維持2-3周后,用無菌的10ml吸管收獲10-20個(gè)獨(dú)立的細(xì)胞菌落。這些菌落再培養(yǎng)4-7天,吹散并隨后使用全細(xì)胞膜片鉗記錄技術(shù)和RT-PCR檢測通道表達(dá)。
E.測量鈉流的方法使用膜片鉗位(clamp)方法測定鈉流(Hamill等,(1981)Pflugers Arch.391,85-100),如Rizzo等,(1994)神經(jīng)生理學(xué)雜志72,2796-2815和Dib-Hajj等,(1997)FEBS Lett.416,11-14所述。這些記錄要在MacIntosh Quadra 950或相似的計(jì)算機(jī)上使用例如Pulse(v 7.52,HEKA German)等程序才能獲得。用Sutter P-87拉制器或相似儀器將毛細(xì)玻璃管制成常規(guī)玻璃燒邊的電極(0.8-1.5MW)。在最嚴(yán)密的分析中,通常只考慮分析下列細(xì)胞如果初始絕緣(seal)電阻小于5Gohm,有高漏電電流(-80mV的保持電流小于0.1nA),膜起泡,且接通電阻(access resistance)小于5Mohm。通常通過實(shí)驗(yàn)監(jiān)測接通電阻而且如果電阻發(fā)生改變則數(shù)據(jù)不可用。用一系列電阻補(bǔ)償降低電壓誤差并且用計(jì)算機(jī)控制的放大器回路或其它相似方法取消電容假象。為對比激活和失活作用的電壓依賴性,使用補(bǔ)償后最大電壓誤差在±10mV的細(xì)胞。線性漏電減法通常用于電壓鉗位記錄。通常以5KHz過濾膜電流并以20KHz采樣。電極液(pipette solution)包含標(biāo)準(zhǔn)溶液例如140mM CsF,2mMMgCl2,1mM EGTA,和10mM Na-HEPES(pH7.3)。標(biāo)準(zhǔn)浴液通常是140nMNaCl,3mM KCl,2mM MgCl2,1mM CaCl2,10mM HEPES,和10mM葡萄糖(pH7.3)。
在轉(zhuǎn)化的細(xì)胞或DRG神經(jīng)元上用諸如細(xì)胞內(nèi)膜片鉗位記錄等方法進(jìn)行電壓鉗位研究,可提供鈉流強(qiáng)度的定量測定(并因此提供細(xì)胞中的鈉通道數(shù)),以及通道的生理學(xué)特征。測量通過諸如鈉通道等離子通道的離子流的這些技術(shù),參見Rizzo等,(1995)Neurobiol Dis.2,87-96?;蛘邔︹c通道功能的阻斷或增強(qiáng)可以用鈉敏感染料或同位素標(biāo)記的鈉經(jīng)光學(xué)顯像檢測。Rose等,(1997)神經(jīng)生理學(xué)雜志78,3249-3258和(Kimelberg和Waltz,(1988)神經(jīng)元的微環(huán)境(Boulton等主編)Humana發(fā)行)描述的這些方法可測量鈉通道開放時(shí)細(xì)胞內(nèi)鈉離子濃度的增加。
F.細(xì)胞內(nèi)鈉[Na+]i的測定各種試劑對表達(dá)Na+的細(xì)胞的影響可以用SBFI或其它相似的離子敏感型染料經(jīng)[Na+]i比率度量顯像測定。在此方法中,如Sontheimer等,(1994)神經(jīng)科學(xué)雜志14,2464-2475中所述,用Na+指試劑如SBFI(鈉結(jié)合型苯并呋喃異鄰苯二甲酸酯(Harootunian等,(1989)生物學(xué)和化學(xué)雜志264,19458-19467))或相似染料測定胞質(zhì)內(nèi)游離Na+。首先在細(xì)胞中添加該染料的膜通透型乙酰氧甲基酯形式(溶于二甲亞砜中,貯存濃度為10mM)。用比率度量顯像裝置(例如,買自Georgia Instruments)在顯微鏡下進(jìn)行記錄。使用合適波長(例如,340385nm)的激發(fā)光。激發(fā)光通過二色性反光鏡(400nm)射向細(xì)胞,收集450nm以上的發(fā)射光。熒光信號用例如圖像增強(qiáng)儀(GenIISyS)放大,并用與幀接收器相連的CCD照相機(jī)或類似裝置收集。為計(jì)算熒光衰減,使用熒光比率340385評定胞質(zhì)的游離Na+。
為了校準(zhǔn)SBFI的熒光,在細(xì)胞中灌注含有已知鈉濃度(通常0和30mM,或0,30,和50mM[Na+]的校準(zhǔn)溶液,并且在每次實(shí)驗(yàn)后灌注諸如短桿菌肽和莫能菌素(見上面)等離子載體(ionophone)。如Rose和Ransom,(1996)生理學(xué)雜志(Lond)491,291-305所報(bào)道,細(xì)胞內(nèi)SBFI的345/390nm熒光比率單純隨著[Na+]i變化。實(shí)驗(yàn)一般在多個(gè)不同的蓋玻片(一般至少4個(gè))上重復(fù),以便對對照細(xì)胞和暴露于各種濃度的可能阻斷、抑制或增加Na+的試劑的細(xì)胞中的胞內(nèi)鈉進(jìn)行統(tǒng)計(jì)學(xué)顯著性測量。
G.通過測量22Na或86Rb而測量Na+流入的方法22Na是γ發(fā)射者,可用于測量Na+流(Kimelberg和Waltz,(1988)神經(jīng)元的微環(huán)境(Boulton等主編)Humana發(fā)行),而86Rb+可用來測定Na+/K+-ATP酶的活性(Sontheimer等,(1994)神經(jīng)科學(xué)雜志14,2464-2475)。86Rb+離子被Na+/K+-ATP酶樣K+離子吸收,但具有比42K+更長半衰期的優(yōu)勢(Kimelberg和Mayhew(1975)生物學(xué)和化學(xué)雜志250,100-104)。因此,對哇巴因敏感型86Rb+單向攝取的測定提供了定量測定Na+/K+-ATP酶活性(神經(jīng)細(xì)胞電激活的又一指示劑)的方法。將表達(dá)NaN的細(xì)胞用放射性22Na+保溫后,用液閃計(jì)數(shù)儀或相似方法測定放射性同位素的細(xì)胞內(nèi)含量,并用諸如二辛可寧酸蛋白測定法(Smith等,(1985)Anal Biochem 150,76-85)經(jīng)Goldschmidt和Kimelberg(1989)Anal.Biochem.177,41-45針對培養(yǎng)細(xì)胞而改良后的方法測定細(xì)胞蛋白。在存在和缺乏可能阻斷、抑制、或增強(qiáng)NaN的試劑的情況下,測定22Na流和86Rb+流。這允許測定這些試劑對NaN的作用。
H.對能調(diào)節(jié)NaN介導(dǎo)型離子流的試劑進(jìn)行鑒定的方法可以使用幾種方法鑒定能夠調(diào)節(jié)(即阻斷或放大)通過NaN鈉通道的Na+流的試劑。通常為鑒定這些試劑,使用能表達(dá)NaN鈉通道的培養(yǎng)細(xì)胞系模型,并且使用一種或多種傳統(tǒng)測定法測定Na+流。這些傳統(tǒng)測定法包括,例如,膜片鉗位法,[Na+]i比率度量顯像以及上述22Na和86Rb的使用。
在本發(fā)明的一個(gè)實(shí)施方案中,為評價(jià)待選化合物調(diào)節(jié)Na+流的活性,將試劑與合適的表達(dá)NaN的轉(zhuǎn)化宿主細(xì)胞接觸?;旌匣虮剡m當(dāng)?shù)臅r(shí)間后,測定Na+流以測定該試劑是否抑制或增強(qiáng)Na+流流動。
抑制或增強(qiáng)Na+流的試劑因此被鑒定。本領(lǐng)域的技術(shù)人員可輕易使用多種本領(lǐng)域已知技術(shù)測定特定試劑是否能調(diào)節(jié)Na+流流動。
由于Na+優(yōu)先在痛覺信號細(xì)胞上表達(dá),也可通過測定用這些試劑處理過的實(shí)驗(yàn)動物對急性,炎性或慢性痛的反應(yīng)而設(shè)計(jì)能阻斷,抑制,或增強(qiáng)Na+通道功能的試劑。在本發(fā)明這方面的一個(gè)實(shí)施方案中,用試劑例如阻斷或抑制(或者認(rèn)為是阻斷或抑制)NaN的試劑處理如大鼠等實(shí)驗(yàn)動物。然后用諸如甩尾實(shí)驗(yàn)和縮爪反射等實(shí)驗(yàn)測定對各種痛刺激的反應(yīng),并與未處理的對照組比較。這些方法見Dubner,(1994)Text book of Pain(Wall & Melzack,主編)Churchill Livingstone Publishers。在本發(fā)明此方面的另一實(shí)施方案中,對諸如大鼠的實(shí)驗(yàn)動物局部注射產(chǎn)生痛覺的致炎性試劑例如福爾馬林(Dubuisson & Dennis(1977)疼痛4,161-74),弗氏佐劑(Iadarola等,(1988)疼痛35,313-326)或者carageenan,或者使之接受能產(chǎn)生持續(xù)疼痛的神經(jīng)收縮(Bennett & Xie,(1988)疼痛33,87-107;Kim & Chung(1992)疼痛50,355-363)或者神經(jīng)橫切(Seltzer等,(1990)疼痛43,205-218)。然后通過如測定從溫或熱刺激縮爪的潛伏期(Dubner,(1994)Textbook of Pain(Wall &Melzack,主編)Churchill Livingstone Publishers)而測定對多種正常和痛性刺激的反應(yīng),以便與對照動物以及用據(jù)認(rèn)為能改變NaN的試劑處理的動物進(jìn)行比較。
優(yōu)選的NaN抑制劑和增強(qiáng)劑對NaN Na+通道有選擇性。它們可以是完全特異性的(如河豚毒素,TTX,其抑制鈉通道但是不結(jié)合或直接影響其它通道或受體),或者相對特異性的(例如利多卡因,其結(jié)合并阻斷幾種類型的離子通道,但是對鈉通道有所偏重)。對于有功效的抑制劑或增強(qiáng)劑不要求完全特異性。其對鈉通道與對其它通道和受體的作用比通??蓻Q定它對除靶目標(biāo)以外的若干通道的作用,并且是有效的(Stys等,(1992)神經(jīng)生理學(xué)雜志67,236-240)。NaN調(diào)節(jié)劑可以與能調(diào)節(jié)初級感覺神經(jīng)元上表達(dá)的其它通道的試劑聯(lián)合給藥或共給藥,這些試劑包括但不限于PN1/hNE和SNS/PN3(Waxman(1999)疼痛增刊6S133-140)。

初級RACE擴(kuò)增在終體積50ml中進(jìn)行,使用4ml稀釋的DRG marathoncDNA模板,0.2mM marathon AP-1和NaN-特異引物,3.5單位的擴(kuò)增長模板酶混合物。根據(jù)想要的產(chǎn)物將延長期調(diào)節(jié)為每800個(gè)堿基對1分鐘。分別使用引物對marathon AP-1/NaN-特異性R6和NaN-特異性F5/marathonAP-1進(jìn)行5’和3’RACE擴(kuò)增。PCR反應(yīng)緩沖液包括50mM Tris-鹽酸(pH9.2),16mM(NH4)2SO4,3.0mM MgCl2,2%(v/v)DMSO和0.1%吐溫20。用可編程熱循環(huán)儀(PTC-200,MJ Research)在三個(gè)階段進(jìn)行擴(kuò)增。起始變性步驟92℃2分鐘,隨后是92℃變性20秒,60℃退火1分鐘,和68℃延伸的35個(gè)循環(huán)。最后,在68℃延伸5分鐘。嵌套式擴(kuò)增在與初級RACE反應(yīng)相同的條件下用2ml 1/500稀釋的初級RACE產(chǎn)物在終體積50ml中進(jìn)行。分別使用引物對AP-2/NaN-特異性R7和NaN-特異性F6/marathon AP-2進(jìn)行嵌套式5’和3’RACE擴(kuò)增。次級RACE產(chǎn)物用1%瓊脂糖凝膠分帶分離并且用Qiaex凝膠提取試劑盒(Qiagen)純化。
NaN假定結(jié)構(gòu)如圖3所示。不同亞單位之間細(xì)胞內(nèi)環(huán)的序列和長度差異很大。例外的是在結(jié)構(gòu)域III和IV之間的環(huán)。

使用3-磷酸甘油醛脫氫酶(GAPDH)作為內(nèi)部對照以確保不同組織中NaN信號的缺失不是由于模板的降解或PCR抑制物的存在。用擴(kuò)增對應(yīng)于核苷酸328-994(錄入號M17701)的66bp產(chǎn)物的引物共擴(kuò)增大鼠GAPDH序列。以人類基因結(jié)構(gòu)為基礎(chǔ),擴(kuò)增產(chǎn)物跨越多個(gè)外顯子/內(nèi)含子剪接位點(diǎn)(Benham等,(1987)自然328,275-278)。在反轉(zhuǎn)錄之前用DNA酶I常規(guī)處理以防止GAPDH序列從可能污染總RNA制劑的基因組加工型假基因而擴(kuò)增(Ercolani等,(1988)生物學(xué)和化學(xué)雜志263,15335-15341)。
NaN主要且優(yōu)選在DRG和三叉神經(jīng)節(jié)神經(jīng)元中表達(dá)。圖4顯示用RT-PCR在各種神經(jīng)和非神經(jīng)組織中篩選NaN表達(dá)的結(jié)果。泳道1,2,4,9和16表示與400bp標(biāo)志共同電泳的單個(gè)擴(kuò)增產(chǎn)物,其與392bp的NaN-特異產(chǎn)物相一致。泳道1,2,4,9和16含有分別用DRG,大腦半球,視網(wǎng)膜,和三叉神經(jīng)節(jié)獲得的產(chǎn)物。用此評價(jià)方法,在小腦,視神經(jīng),脊髓,坐骨神經(jīng),頸上神經(jīng)節(jié),骨骼肌,心肌,腎上腺,子宮,肝或腎(分別是泳道3,5-8和10-15)未檢測到NaN。由于在平行PCR反應(yīng)(數(shù)據(jù)未顯示)中獲得了相當(dāng)?shù)腉APDH擴(kuò)增產(chǎn)物,所以在大腦半球和視網(wǎng)膜上NaN信號減弱,在其余組織上此信號缺失不是由于RNA的降解或在cDNA模板中PCR抑制物的存在。

前面的研究顯示坐骨神經(jīng)橫斷誘導(dǎo)了軸突橫切術(shù)后的DRG神經(jīng)元鈉流的戲劇性變化,這與這些神經(jīng)元上表達(dá)的各種鈉通道的明顯轉(zhuǎn)錄變化相一致。在快速再啟動的靜止TTX-S離子流出現(xiàn)時(shí)和產(chǎn)生TTX-S離子流的α-III鈉通道的轉(zhuǎn)錄上調(diào)時(shí),為TTX-R型的鈉流和兩種TTX-R鈉通道(SNS/PN3和NaN)的轉(zhuǎn)錄明顯減弱。我們已經(jīng)發(fā)現(xiàn)術(shù)后14天,CCI-誘導(dǎo)的DRG神經(jīng)元上的改變和軸突切開術(shù)后的改變完全相同。當(dāng)在小直徑DRG神經(jīng)元上TTX-Sα-III鈉通道的轉(zhuǎn)錄上調(diào)時(shí),兩種感覺神經(jīng)元特異性TTX-R通道,NaN和SNS的轉(zhuǎn)錄明顯下調(diào),TTX-R鈉流也一樣。這些改變可能部分造成DRG神經(jīng)元興奮性過高,其與該創(chuàng)傷后引起的痛覺過敏有關(guān)。

將待測試劑與表達(dá)Na+通道的HEK293或其它轉(zhuǎn)化細(xì)胞一起保溫(Dib-Hajj等,(1997)FEBS Lett.416,11-14)。保溫足夠的時(shí)間后,可用膜片鉗位方法測量該試劑誘導(dǎo)的Na+通道活性的改變(Hamill等,(1981)Pflugers Arch.391,85-100)。這些測量的數(shù)據(jù)要在MacIntosh Quadra 950或相似的計(jì)算機(jī)上使用例如Pulse(v7.52,HEKA German)等程序才能獲得。用Sutter P-87拉制器或相似儀器將毛細(xì)玻璃管制成玻璃燒邊的電極(0.8-1.5MW)。通常只考慮分析下列細(xì)胞如果初始絕緣電阻小于5Gohm,有高漏電電流(-80mV的保持電流小于0.1nA),膜起泡,且接通電阻小于5Mohm。監(jiān)測接通電阻而且如果電阻發(fā)生改變則數(shù)據(jù)不可用。用一系列電阻補(bǔ)償來降低電壓誤差并且用計(jì)算機(jī)控制的放大器回路或其它相似方法取消電容假象。
為對比激活和失活的電壓依賴性,通常使用補(bǔ)償后最大電壓誤差<10mV的細(xì)胞。線性漏電減法通常用于電壓鉗位記錄。通常以5KHz過濾膜電流并以20KHz采樣。電極液包含標(biāo)準(zhǔn)溶液例如140mM CsF,2mM MgCl2,1mM EGTA,和10mM Na-HEPES(pH7.3)。標(biāo)準(zhǔn)浴液通常是140nM NaCl,3mM KCl,2mM MgCl2,1mM CaCl2,10mM HEPES,和10mM葡萄糖(pH7.3)。
河豚毒素(TTX)-抗性和TTX-敏感性Na+流的測定通過暴露于適當(dāng)濃度的TTX和/或通過預(yù)脈沖方案完成,此方案可根據(jù)TTX-敏感的和TTX-抵抗的離子流各自的靜息狀態(tài)失活特性區(qū)分它們(Cummins & Waxman(1997)神經(jīng)生理學(xué)雜志17,3503-3514;Sontheimer & Waxman(1992)神經(jīng)生理學(xué)雜志68,1001-1011)。
用標(biāo)準(zhǔn)脈沖方法收集數(shù)據(jù)并分析以測定包括下列的鈉通道特性電壓依賴性,靜息狀態(tài)特征,動力學(xué),和再啟動。電流幅度和細(xì)胞電容的測定提供了Na+流強(qiáng)度的估計(jì)值,因此允許在不同條件下對比通道密度(Cummins & Waxman(1997)神經(jīng)生理學(xué)雜志17,3503-3514,30)。細(xì)胞在電流鉗位模式下研究自發(fā)型和激型動作電位的產(chǎn)生模式,激活閾值,頻率應(yīng)答特征,和對去極化和超極化的反應(yīng),和其它電生成方面(Sontheimer &Waxman(1992)神經(jīng)生理學(xué)雜志68,1001-1011)。這些測定既在表達(dá)NaN的對照組細(xì)胞上完成也在暴露于被測試劑的NaN表達(dá)細(xì)胞上完成。

為了校準(zhǔn)SBFI的熒光,在細(xì)胞中灌注含有已知鈉濃度(通常0和30mM,或0,30,和50mM[Na+]的校準(zhǔn)溶液,以及短桿菌肽和莫能菌素。如Rose和Ransom,(1996)生理學(xué)雜志(Lond)491,291-305所報(bào)道,細(xì)胞內(nèi)SBFI的345/390nm熒光比率單純隨著[Na+]i變化。實(shí)驗(yàn)一般在多個(gè)不同的蓋玻片(一般至少4個(gè))上重復(fù),以便對對照細(xì)胞和暴露于各種濃度的可能阻斷、抑制或增加Na+的試劑的細(xì)胞中的胞內(nèi)鈉進(jìn)行統(tǒng)計(jì)學(xué)顯著性測量。此方法的使用如Sontheimer等,(1994)神經(jīng)科學(xué)雜志14,2464-2475所述。

將表達(dá)NaN的細(xì)胞用放射性同位素保溫后,用液閃計(jì)數(shù)儀或相似方法測定放射性同位素的細(xì)胞內(nèi)含量,并用諸如二辛可寧酸蛋白測定法(Smith等,(1985)Anal Biochem 150,76-85)經(jīng)Goldschmidt和Kimelberg(1989)Anal.Biochem.177,41-45針對培養(yǎng)細(xì)胞而改良后的方法測定細(xì)胞蛋白。在存在和缺乏可能阻斷、抑制、或增強(qiáng)NaN的試劑的情況下,測定22Na流和86Rb+流。這允許測定這些試劑對NaN的作用。
