abstract：:The expression of normal and mutant ras genes in human acute leukemias was assessed by the direct analysis of p21ras polypeptides, using immunoprecipitation with monoclonal antibodies. High-resolution two-dimensional gel electrophoresis permits the identification of a wide array of activated ras alleles encoding prote...

abstract：:Homozygous mutations of the recessive oncogene lethal-(2) giant larvae (l(2)gl) of Drosophila melanogaster cause lethal neoplasms of the imaginal discs and the brain hemisphere. A 13-kb DNA segment spanning the l(2)gl+ locus has been inserted into P element vectors and used for P-mediated transformation. The P-l(2)gl+...

abstract：:Abnormalities in structure and expression of the proto-oncogene c-abl have been implicated in the genesis of chronic myelogenous leukemia (CML). We studied leukemic cell DNA from 42 CML patients for evidence of rearrangement and/or amplification of c-abl analogous to that described in the CML cell line K562. Using the...

abstract：:Oncogenes in DNAs from human tumor cell lines have been detected by a new transformation assay. Cellular DNAs are transfected into NIH3T3 murine fibroblasts, and transformed cells are selected by maintaining cell cultures in a defined medium lacking platelet-derived or fibroblast growth factors. DNAs from eight of 17 ...

abstract：:Tumor-derived DNA from a non-Hodgkin's (T cell) lymphoma patient, assayed by NIH3T3 transfection followed by inoculation of cells into nude mice, was found to contain an activated N-ras proto-oncogene. The mode of activation was determined by hybridization with N-ras-specific oligonucleotide probes detecting mutations...

abstract：:Adenovirus contains two nuclear oncogenes, the EIA and EIB genes, which cooperatively can transform cells through mechanisms that are not understood. The transcriptional activities of the E1A gene (transactivation and repression) are well studied. Using transient expression assays, we show here that the 19,000-Da E1B ...

abstract：:The c-myc oncogene is the most extensively studied member of the myc gene family which now consists of three characterized members, namely the c-myc, N-myc and L-myc genes. These genes are often found amplified in cell lines from small cell carcinomas of the lung (SCLC). In this study the L-myc gene was examined in a ...
