The pressor effect of adenosine was due to carotid body cheoreceptor activation. However, a slight increase of ABP induced by intracarotid bolus injection of adenosine following the section of carotid sinus nerves was observed in a few rats, which implied that the central effect might be involved in the pressor effect of adenosine. The delayed effect of adenosine may be attributed to the direct actions (including the negative chronotropic action, thenegative dromotropic action, the negative inotropic action and the vasodilator effect) of adenosine on the heart and blood vessels.

前一效应主要与颈动脉体化学感受器的激活有关，但在少数动物，颈动脉内注射腺苷的升压效应在切除窦神经后并未完全消除，表明腺苷有可能进入神经中枢而发挥作用；后一效应可能由腺苷直接作用于心脏和血管，通过其负性变力、变时、变传导和血管扩张等作用，导致心脏自律性降低，输出量减少和外周阻力下降。

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。
