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。

Our interpretation of the results from parsimony, distance and maximum likelihood based phylogenetic analyses suggest:(1) African colobines and Asian colobines have been independent evolutionary entities for a long time; the divergent time is estimated to occur 10 million years ago based on a molecular clock of 2% substitution per site per million years;(2) both Rhinopithecus and Trachypithecus could be regarded as separate genus;(3) Pygathrix and Rhinopithecus are sister groups while Presbytis and Trachypithecus are closely related;(4) both the Sichuan and Yunnan snub-nosed monkey represent valid species respectively;(5) within genus Trachypithecus, T. phayrei is closely related to T. cristatus and T. auratus, while T. francoisi is distinct from them; the white-headed leaf monkey, however, should be a subspecies of T. francoisi;(6) within genus Presbytis, P. thomasi should be separated as a valid species from P. melalophos, but the genetically divergent degree between P. comata and P. melalophos implies that P. comata may just be a subspecies of P. melalophos.

结果表明：（1）非洲疣猴与亚洲疣猴的分歧已非常明显，按分子钟推算的分歧时间约在1，000万年前；（2）Rhinopithecus和Trachypithecus均应成为独立的属；（3）白臀叶猴属与金丝猴属关系较近，Presbytis属和Trachypithecus属关系也较近；（4）我国的川、滇金丝猴应分别被视为独立的物种；（5）在Trachypithecus属中，菲氏叶猴与银叶猴(T.cristatus)和乌木叶猴亲缘关系较近，黑叶猴(T.francoisi)则与它们的关系较远，曾被怀疑为一个种的白头叶猴(T.f.leucocephalus)应只是黑叶猴的一个亚种；（6）在Presbytis属内，托氏叶猴应从僧帽叶猴(P.melalophos)中独立出来成为一个有效种，但我们的结果倾向于将灰发叶猴置为僧帽叶猴的一个亚种。

Researchers expected that the gene responsible would vary from lake to lake. Instead, they found that each group of stranded sticklebacks had lost its armor by the same mechanism: a rare DNA defect affecting a signaling molecule involved in the development of dermal bones and teeth. That single preexisting variant--rare in the open ocean--allowed the fish to adapt rapidly to a new environment.
