    摘要: Serial analysis of gene expression, SAGE, a method for the rapid quantitative and qualitative analysis of transcripts is provided. Short defined sequence tags corresponding to expressed genes are isolated and analyzed. Sequencing of over 1,000 defined tags in a short period of time (e.g., hours) reveals a gene expression pattern characteristic of the function of a cell or tissue. Moreover, SAGE is useful as a gene discovery tool for the identification and isolation of novel sequence tags corresponding to novel transcripts and genes.

    摘要: The most well-documented biochemical property of p53 is its ability to transcriptionally activate genes. Many of the genes which are activated by p53 expression prior to the onset of apoptosis are predicted to encode proteins which could generate or respond to oxidative stress, including one that is implicated in apoptosis within plant meristems. p53 may result in apoptosis through a three-step process: (I) the transcriptional induction of specific redox-related genes; (ii) the formation of reactive oxygen species (ROS); and (iii) the oxidative degradation of mitochondrial components, rapidly leading to cell death. Transcription of other genes is decreased by p53. Examination of the level of transcription of p53-induced or repressed genes can be used to determine p53 status, to diagnose cancer, and to evaluate cytotoxicity or carcinogenicity of a test agent.

    摘要: As a step towards understanding the complex differences between normal and cancer cells, gene expression patterns were examined in gastrointestinal tumors. More than 300,000 transcripts derived from at least 45,000 different genes were analyzed. Although extensive similarity was noted between the expression profiles, more than 500 transcripts that were expressed at significantly different levels in normal and neoplastic cells were identified. These data provide insights into the extent of expression differences underlying malignancy and reveal genes that are useful as diagnostic or prognostic markers.

    摘要: Five human genes related to the Mad gene of Drosophila were identified. One of these genes (Smad2) was found to reside at chromosome 18q21, adjacent to a previously described member of this family called DPC4 (Smad4). Smad2 was found to be somatically mutated in two of eighteen human colorectal cancers. Smad2 and Smad4 are important in the suppression of neoplasia by mediating the growth inhibitory effects of TGF-&bgr;-like ligands.

    摘要: Recombinant adenoviruses provide a versatile system for gene expression studies and therapeutic applications. This invention describes a strategy which simplifies the generation and production of such viruses. A recombinant adenoviral plasmid is generated with a minimum of enzymatic manipulations, employing homologous recombination in bacteria rather than in eucaryotic cells. Following transfections of such plasmids into a mammalian packaging cell line, viral production can be conveniently followed with the aid of green fluorescent protein, encoded by a gene incorporated into the viral backbone. Homogeneous viruses can be obtained from this procedure without plaque purification. This system expedites the process of generating and testing recombinant adenoviruses.
