Results are as followed:1 Exposure of HELF cells to BP caused c-Jun activation,and increased the activity of MAPK,PI-3K,p53 and cyclin D1 pathway.2 BP-induced c-Jun activation was inhibited by dominant negative mutants of extracellular signal-regulated protein kinase or c-Jun NH_2-terminal kinase,but not by p38,impling that JNK and ERK pathways medicate c-Jun activation induced by BP.3 Overexpression of dominant-negative mutants PI-3K and Akt potently blocked phosphorylations of c-Jun and ERK,but not JNK in response to BP,suggesting that PI-3K/Akt pathway positively regulates BP-induced c-Jun activation through ERK.4 Inhibition of p53 by its chemical or molecular inhibitor markedly increased the phosphorylation levels of c-Jun,Akt and ERK upon BP stimulation,indicating that p53 negatively medicates BP-induced c-Jun activation through PI-3K/Akt/ERK pathway.5 The cell lines expressed TAM67 exhibits no significant affecting normal cell growth properties.6 TAM67 was able to significantly block G_1-S transition and subsequent cell proliferation,suggesting that c-Jun is essential for cell cycle alternations elicited by BP.7 Overexpression of TAM67 impaired BP-induced cyclin D1 activation,decreasing expression of E2F1 and pRb,indicating that c-Jun participates in the modulation of BP-induced activation of cyclin D1/pRb/E2F1 pathway.8 Stably expression of TAM67 led to the increases in the expression levels of p53 and p21,elevating phosphorylation level of p53,clearly indicating that c-Jun regulates p53/p21 pathway activation induced by BRCollectively,PI3K/Akt/ERK pathway mediated BP-induced c-Jun activation through p53-dependent mechanism.
结果显示:1BP刺激细胞可促进c-Jun活化,并伴随着MAPK、PI-3K、p53和cyclinD1通路各组成成分的活性增强。2利用MAPK通路的显性失活突变体分别阻断细胞外信号调节激酶和c-Jun氨基末端激酶活性,均可明显抑制BP诱导的c-Jun活化,但阻断p38活性对BP引起的c-Jun活化无明显影响,提示JNK和ERK通路参与调控BP诱导的c-Jun活化。3过表达PI-3K和Akt的显性失活突变体也可显著抑制BP诱导的c-Jun活化,并降低磷酸化ERK的表达水平,但对磷酸化JNK的表达水平无明显影响,说明PI-3K/Akt通路通过ERK正性调控了BP诱导的c-Jun活化。4p53的化学/分子抑制剂能使BP作用的细胞内c-Jun活性明显增加,并同时诱导Akt和ERK的磷酸化水平的升高,表明p53可通过PI-3K/Akt/ERK通路对BP诱导的c-Jun活化进行负性调控。5随后观察转染细胞的生长情况,发现TAM67对细胞正常生长和形态无明显影响。6稳定表达TAM67可有效抑制BP诱导的S期细胞数的增加,提示c-Jun在BP致细胞周期改变的过程中发挥了重要作用。7TAM67过表达能够抑制BP诱导的cyclin D1活化,降低磷酸化Rb以及E2F1蛋白表达水平,表明c-Jun参与调控BP诱导的cyclin D1/Rb/E2F1通路的活化。8过表达TAM67可使BP刺激的细胞中p53、p21总蛋白以及p53磷酸化的表达水平明显升高,可见c-Jun也参与调控BP诱导的p53/p21通路活化。

In the spiral pipe heat exchanger exports terminal, the ammonia steam temperature has been heated up 85 ℃--95 ℃, by now, the ammonia steam had the 45kg-55kg/cm2 ammonia steam pressure, sent in the ammonia steam turbine through the constant temperature pipeline, impelled ammonia steam turbine revolving, led the generator electricity generation;After the ammonia steam makes the merit release energy, the temperature drop, the returns ammonia storage tank, passes through again adjusts the press pump to press into the spiral pipe-type heat exchangers to carry on the next circulation;Including the ammonia steam turbine entire ammonia steam road is becomes the independent closed cycle system, is isolates completely with the outside air;The ammonia steam only plays the carryhome and the shift energy role, in the electricity generation process does not consume the actuating medium, the stored energy carrier water also is only gets up the carryhome and the shift energy function,The waterway also is from becomes the independent closed cycle system, in the electricity generation process also the needless water consumption, through the actuating medium ammonia steam and the stored energy carrier water unceasing shuttle service, transforms through the heat interchanger the solar energy as the actuating medium ammonia steam heat energy and the kinetic energy,With the aid of the ammonia steam turbine heat - machine transformation function and the generator machine - electricity transformation function, has realized the solar energy hot - electricity entire conversion process, transforms continuously the solar energy into the electrical energy, power supply for foreign;The low temperature generating system must solve three big technical keys:One, the anticorrosion (has actuating medium has strong corrosiveness), two is Explosion-proof (Some actuating medium Can have the detonation with the air mix when divulging, controls warm malfunction, elevates temperature suddenly also can have detonation), three is guards against the revolution axis divulging
以太阳能低温发电系统为例,低温发电方法是这样进行的:以水作为储能载体的太阳能采集器将太阳能采集起来,将水温提升至85℃--98℃;用氨作为工作介质储于氨储罐及氨汽路中;采用螺旋管型热交换器;用调压泵将氨储罐中的氨汽压入螺旋管型热交换器的螺旋管内,用调压泵将携带太阳能的85℃--98℃的储能载体热水压入螺旋管型热交换器的螺旋管外壁空间进行循环式热交换,在热交换器的螺旋管出口端,氨汽温度已被加热到85℃--95℃,这时,氨汽具有45kg—55kg/cm2的氨汽压力,通过恒温管道送入氨汽轮机,推动氨汽轮机旋转,带动发电机发电;氨汽作功释放能量后,温度下降,返回氨储罐,再经调压泵压入螺旋管型热交换器进行下一次循环;包括氨汽轮机在内的整个氨汽汽路是自成独立的封闭循环系统,与外界空气是完全隔绝的;氨汽只起携带和转移能量的作用,发电过程中并不消耗工作介质,储能载体水也是只起携带和转移能量的作用,水路也是自成独立的封闭循环系统,发电过程中也不消耗水,通过工作介质氨汽和储能载体水的不断循环运行,通过热交换器将太阳能转化为工作介质氨汽的热能和动能,借助氨汽轮机的热—机转化功能和发电机的机—电转化功能,实现了太阳能的整个热—电转化过程,将太阳能源源不断地转变为电能,对外供电;低温发电系统要解决的三大技术关键:一是防腐(有的工作介质具有较强的腐蚀性)、二是防爆(有的介质泄漏与空气混合会产生爆炸,控温失灵,急剧升温也会产生爆炸)、三是防轴漏(汽轮机是动态旋转体,必须解决工作介质的防轴漏问题)。

activation energy:活化能
催化剂可使化学反应物在不改变的情形下,经由只需较少活化能(activation energy)的路径来进行化学反应. 而通常在这种能量下,分子不是无法完成化学反应,不然就是需要较长时间来完成化学反应. 但在有催化剂的环境下,分子只需较少的能量即可完成化学反应.
