查询词典 piecewise regulated function

Down-regulated expression of PTEN and up-regulated expression of VEGF〓 were considered as two important events in tumorigenesis of ovarian cancer and could act as molecular markers to indicate the pathobiological behaviors of ovarian cancer. Decreased PTEN expression and increased VEGF〓 expression were closely associated with tumorigenesis and pathobiological behaviors of ovarian endometrioid and serous cancer respectively. Reduced expression of PTEN gene might be involved in carcinogenesis and progression of ovarian cancer by up-regulating the VEGF〓 expression to enhance angiogenesis.

在卵巢癌组织中PTEN基因mRNA表达下调和VEGF〓基因mRNA表达上调是卵巢癌发生的重要分子事件，可作为反映卵巢癌病理生物学行为的指标，且分别与卵巢内膜样癌和浆液性囊腺癌的发生和病理生物学行为关系密切；PTEN基因mRNA表达降低可能通过上调VEGF〓基因mRNA表达促进新生血管形成，进而参与卵巢癌的发生和侵袭。

To elucidate the molecular mechanisms underlying the neural plasticity after CNS injury, the gene expression profile in the rat hippocampus following perforant path transections was explored by several methods including custom differential screening, custom cDNA array and cDNA microarray. Of 2300 cDNA clones from low-abundance rat brain cDNA bank, 6 were identified as differentially expressed genes/ESTs in the hippocampus 35 days after lesion, in which none was confirmed by Northern blot. Of 8000 cDNA elements, custom cDNA array identified 47 as differentially expressed genes/ESTs with above 3-fold changes in the hippocampus 35 days after lesion, in which 25 were up-regulated and 22 down-regulated.
