AMG 9810 is a vanilloid receptor 1 (VR1 or TRPV1) antagonist, with IC50 values for human TRPV1 of 24.5±15.7 nM, for rat TRPV1 of 85.6 ±39.4 nM as a competitive antagonist of capsaicin activation. To block protons, its IC50 values for rat TRPV1 is 294±192 nM, for human TRPV1 is 92.7±72.8 nM. To block heat, its IC50 value for rat TRPV1 is 21±17 nM, for human TRPV1 is 15.8±10.8 nM. It can also block endogenous ligands, such as N-arachidonyl dopamine, anandamide and oleoyldopamine [1].
TRPV1 is expressed by peripheral sensory neurons. It is a membrane-bound, nonselective cation channel [1].
In rat dorsal root ganglia neurons with the presence of endogenous TRPV1, 45Ca2+ uptake was induced by capsaicin in a dose-dependent manner, the EC90 value is 300 nM. In a Ca2+-dependent manner, capsaicin induces CGRP release through the activation of TRPV1. Capsaicin at 300 nM induced a greater level of CGRP release from cultured neurons into the media, compared with the basal level. Capsaicin-induced 45Ca2+ uptake and CGRP release was potently blocked by AMG 9810 with IC50 values of 9±6 nM and 6±3 nM, respectively. AMG 9810 alone up to 10 ?M had no effect on the basal 45Ca2+ uptake or CGRP release of exposed neurons [1].
In animals capsaicin induced eye wipes. Intraperitoneally, AMG 9810 at 3, 10, and 30 mg/kg, dose-dependently decrease this effect at 15 min. Treatment with AMG 9810 at 10 and 30 mg/kg, 30 min before capsaicin treatment, statistically significantly reduced the number of eye wipes. Only treatment with AMG 9810 at 30 mg/kg 60 min before capsaicin administration significantly reduced eye wipes. Vehicle did not affect capsaicin-evoked eye wipes [1].

先提取RNA,反转录成cDNA,然后根据目的基因设计PCR引物,通过半定量RT-PCR确定目的基因表达.
正因为检测的是mRNA,所以要先反转录成cDNA才能PCR.
1.将外源基因插入慢病毒载体
2.将构建完成的载体与慢病毒包装质粒混合,共转染靶细胞
3.收集病毒液
4.用病毒液感染靶细胞
5.用载体上带的抗生素进行筛选,如果没有,可以用无限稀释法
6.获得稳转株
一种是脂质体转染后,单克隆筛选稳定细胞株.另外一种是应用逆转录病毒,慢病毒转染,筛选稳定细胞株.
脂质体转染:在转染24小时后,消化细胞并计数.将细胞种到96孔板,保证每个孔2-3个细胞,这样才能得到单克隆.待细胞贴壁后,加入抗生素筛选.筛选时间和浓度视细胞而定.一般G418一个星期作用,嘌呤霉素2-3天.
脂质体法筛单克隆时间较长,且效率低,大概只有1%.
病毒转染:先要用包装细胞,一般为293细胞,包装出病毒,再用病毒转染目的细胞.包装病毒视不同类型的病毒而定,一般要3-5天的时间.包装好的病毒要测滴度,根据滴度决定转染目的细胞的病毒量.转染目的细胞1-2天后加抗生素筛选得到稳定细胞株.
病毒转染得到稳定细胞株的效率高,只是步骤繁琐.
细胞转染是指将外源分子如DNA,RNA等导入真核细胞的技术。随着分子生物学和细胞生物学研究的不断发展,转染已经成为研究和控制真核细胞基因功能的常规工具。在研究基因功能、调控基因表达、突变分析和蛋白质生产等生物学试验中,其应用越来越广泛。
方法
脂质体转染法
阳离子脂质体表面带正电荷,能与核酸的磷酸根通过静电作用,将DNA分子包裹入内,形成DNA脂复合物,也能被表面带负电的细胞膜吸附,再通过融合或细胞内吞进入细胞。脂质体转染适用于把DNA转染入悬浮或贴壁培养细胞中,是目前实验室最方便的转染方法之一,其转染率较高,优于磷酸钙法。由于脂质体对细胞有一定的毒性,所以转染时间一般不超过24小时。常用细胞类型:cos-7 、BHK、NIH3T3 、Hela等。
电穿孔转染法
电流能够可逆地击穿细胞膜形成瞬时的水通路或膜上小孔促使DNA分子进入胞内,这种方法就是电穿孔。当遇到某些脂质体转染效率很低或儿乎无法转入时建议用电穿孔法转染。一般情况下,高电场强度会杀死50%-70% 的细胞。现在针对细胞死亡开发出了一种电转保护剂,可以大大的降低细胞的死亡率,同时提高电穿孔转染效率。
病毒感染
对于脂质体转染与电穿孔转染都无法成功转染的细胞系建议用病毒感染,此法可以快速100%感染,检测成功率高。
常用步骤
1. 转染试剂的准备
① 将400ul去核酸酶水加入管中,震荡10秒钟,溶解脂状物。
② 震荡后将试剂放在-20摄氏度保存,使用前还需震荡。
2. 选择合适的混合比例(1:1-1:2/脂质体[1]体积:DNA质量)来转染细胞。在一个转染管中加入合适体积的无血清培养基。加入合适质量的MyoD或者EGFP的DNA,震荡后在加入合适体积的转染试剂,再次震荡。
3. 将混合液在室温放置10―15分钟。
4. 吸去培养板中的培养基,用PBS或者无血清培养基清洗一次。
5. 加入混合液,将细胞放回培养箱中培养一个小时。
6. 到时后,根据细胞种类决定是否移除混合液,之后加入完全培养基继续培养24-48小时。

由于质粒的不兼容性,拥有同种复制子的质粒不能在同一细胞内稳定共存,经过几代的复制,会质粒丢失,所以并不是任何两个或两个以上质粒都可以在同一细胞内稳定存在,但是可以同时进入.
稳定转染的细胞株,就是转染后质粒可以稳定整合到基因组上不会因细胞分裂而丢失。区别于质粒瞬时转染不能长时间保留质粒在细胞里。
