| 背景资料 | During vertebrate embryogenesis, a left right axis is established. Secreted growth factors of the TGF beta family, including gene products derived from nodal, lefty 1 and lefty 2, play crucial roles in establishing left right asymmetries. TGF beta (Transforming growth factor beta) is a pleiotropic cytokine that regulates growth and differentiation of diverse types of cells. TGF beta actions are directed by ligand induced activation of TGF beta receptors. Complexes formed move into the nucleus, where they act as components of a transcriptional complex. Lefty, a novel member of the TGF beta superfamily, inhibits TGF beta signaling. Lefty acts to inhibit phosphorylation of Smad2 following activation of the TGF beta receptor. Lefty also inhibits events downstream from R Smad phosphorylation. Lefty provides a repressed state of TGF beta responsive genes. The Lefty family is comprised of Lefty 1 and Lefty 2 in mouse, and Lefty A and Lefty B in humans. Members of the TGF beta superfamily require processing for their activation. Cleavage is therefore an essential step for Lefty activation. Lefty is synthesized as a large inactive precursor (41 Kda) that must be endoproteolytically processed to release the bioactive polypeptide (28 kDa and 34 kDa forms). The 28kDa form induces MAPK activity. |

IPMTs的形成可能是致胰腺癌病因的早期作用。胰腺内分泌部的胰岛组织的功能是维系体内糖代谢的重要结构，血糖升高的刺激状态下，其分泌胰岛素的活动加强，但具体的机制尚不明确。Shalev等应用基因芯片技术确定了一批与血糖水平变化相关的基因。有意思的是，转化生长因子β(TGFβ)家族受血糖的高度调节，其中PDF被调节的幅度显著高于该家族的其他成员。这是基因芯片技术导致的又一新发现。基因芯片技术除用于胰腺肿瘤的研究外，也有应用于胰腺炎研究的报道。Samir等的应用高密度小鼠cDNA芯片分析急性胰腺炎期间胰腺
