Abstract
Hereditary papillary renal carcinoma (HPRC) is a newly recognized inherited disorder characterized by a predisposition to develop multiple bilateral papillary renal carcinomas. Individuals affected with HPRC have been shown to have germ-line mutations in the tyrosine kinase domain of the MET proto-oncogene. We identified a novel mutation in exon 16 of the MET gene in two large North American HPRC families. The H1112R MET mutation segregated with the disease, was not present in 320 normal chromosomes, and caused malignant transformation of NIH 3T3 cells. By examining individuals with the H1112R mutation, we determined the age-dependent penetrance of this mutation and identified additional nonrenal malignancies that occurred in mutation carriers. Affected members of the two families shared the same haplotype within and immediately distal to the MET gene, suggesting a founder effect. The identification of the H1112R mutation will facilitate predictive testing in HPRC and guide future studies of the MET gene in human neoplasia.

Abstract
Immunogold labeling electron microscopy technique has been used to study the ultrastructural localization of oncogenic proteins: Mos, Met, Ski, and the tumor-associated protein, Muc1, as well as their relationship with other tumor-related proteins. By pre- and postembedding immunogold labeling electron microscopy techniques, we showed that the Mos protein pp39mos colocalized with microtubule bundles, suggesting that microtubulin or microtubule-associated protein(s) may be the substrate of Mos. Met protein was labeled at the microvilli of the lumen that are formed in cultured T47D cells, implying its potential involvement in lumen formation. Ski localization experiments revealed a unique globular structure "Ski body" that is present inside the nucleus of interphase chicken embryo fibroblast infected with Ski cDNA FB29 and FB2-29. Ski bodies were also found scattered in the cytoplasm of metaphase FB29 and FB2-29 Ski expressing chicken embryo fibroblasts. In T47D cells, tumor-associated protein Muc1 was associated with both the plasma membrane and the membranes of secretory vesicles in the cytoplasm. In MUC1 infected NIH3T3 cells, however, labeling showed that in addition to the plasma membrane and the membranes of secretory vesicles, some Muc1 gold spheres were seen inside the secretory vesicles, suggesting that the subcellular localization of the protein may vary in different cell types.

Abstract
Early in the development of many animals, before transcription begins, any change in the pattern of protein synthesis is attributable to a change in the translational activity or stability of an mRNA in the egg. As a result, translational control is critical for a variety of developmental decisions, including axis formation in Drosophila and sex determination in Caenorhabditis elegans. Previous work demonstrated that increases in poly(A) length can activate translation, whereas removal of poly(A) can prevent it. In this report we focus on the control of c-mos and cyclin A1, B1, and B2 mRNAs during meiotic maturation and after fertilization of frog eggs. We show that addition and removal of poly(A) from these mRNAs is extensively regulated: The time at which each mRNA receives or loses poly(A), as well as the number of adenosines it gains or loses, differ substantially. Signals in the 3'-untranslated region (UTR) of each mRNA are sufficient to reconstitute both the temporal and quantitative control of poly(A) addition: Chimeric mRNAs in which a luciferase-coding region is joined to the 3' UTRs of cyclin A1, cyclin B1, or c-mos mRNA, receive poly(A) of the same length and at the same time as do the endogenous mRNAs. Moreover, each 3' UTR also regulates translation of the chimeric mRNAs, determining when and how much translation of the luciferase reporter is stimulated during maturation. The magnitude of stimulation in luciferase activity varies from 5- to 100-fold, depending on the 3' UTR. Translational stimulation by each 3' UTR requires poly(A) lengthening, as it is prevented by mutations that prevent that process. These results suggest that the 3' UTRs of cyclin and c-mos mRNAs control not only whether or not an mRNA is turned on during maturation, but when that activation occurs and to what extent. Translational control of c-mos mRNA, which may be achieved through regulation of poly(A) length, may be critical in the activation of maturation, and in the onset of cleavage divisions. Our findings, as well as those of others, suggest that even quite complex patterns of translational activation in the early embryo can be attained through the differential control of a common mechanism.

Abstract
We investigated the possible interactions between pp39mos and p34cdc2 kinase in NIH 3T3 cells transformed by c-mosxe. pp39mos is coprecipitated with p34cdc2 when using either anti-PSTAIR antibody or p13suc1-Sepharose beads. Likewise, p34cdc2 is coprecipitated with pp39mos when using anti-mos antibody. However, pp39mos was not present in histone H1 kinase-active p34cdc2 complexes precipitated with anti-p34cdc2 C-terminal peptide antibody even during metaphase of the cell cycle. The molar ratio of p34 to pp39mos in the p13suc1 complex is approximately 2:1. Consistent with the tight association between pp39mos and tubulin, tubulin was also present in equivalent amounts with pp39mos and p34 in the p13suc1 complex. This pp39mos-p34cdc2-tubulin complex may be important in transformation by the mos oncogene.

Abstract
Transgenic mice carrying and expressing a mos protooncogene, linked to the Moloney murine sarcoma virus long terminal repeat, develop severe neurological defects and lens abnormalities. Here we report that after long latent periods, mice in three of four of these mos transgenic lines develop a high frequency of multicentric pheochromocytomas and/or medullary thyroid neoplasms. The pattern of tumor formation is remarkably similar to the human autosomal dominantly inherited neoplastic syndrome, multiple endocrine neoplasia type 2 (MEN 2), and tumors from these transgenic animals display the same neuroendocrine marker staining pattern as seen in MEN 2. The similarity between the tumor pathologies and presentation patterns of MEN 2 patients and mos transgenic mice suggests that they may arise through related pathways. The type of tumor presentation varies in a line-dependent manner indicating that there is interaction between the transgene and the genetic background. Moreover, when the non-tumor-bearing mos transgenic line is crossed to a different mouse background, the F1 offspring display the MEN 2 phenotype. These studies indicate that penetrance of the autosomal dominant mos transgenic phenotype is dependent on both integration site and background.

Abstract
We isolated overlapping cDNA clones corresponding to the major MET protooncogene transcript. The cDNA nucleotide sequence contained an open reading frame of 1408 amino acids with features characteristic of the tyrosine kinase family of growth factor receptors. These features include a putative 24-amino acid signal peptide and a candidate, hybrophobic, membrane-spanning segment of 23 amino acids, which defines an extracellular domain of 926 amino acids that could serve as a ligand-binding domain. A putative intracellular domain 435 amino acids long shows high homology with the SRC family of tyrosine kinases and within the kinase domain is most homologous with the human insulin receptor (44%) and v-abl (41%). Despite these similarities, however, we found no apparent sequence homology to other growth factor receptors in the putative ligand-binding domain. We conclude from these results that the MET protooncogene is a cell-surface receptor for an as-yet-unknown ligand.

Abstract
We used human oncogene DNA to transform the nontumorigenic, revertant, human osteosarcoma cell line HOS TE-85 clone 5 (ATCC CRL 1543) to tumorigenicity in athymic nude mice with latency periods as short as 3 weeks. These cells were also transformed by genetic markers in genomic DNA samples. Because of their low rate of spontaneous tumor formation and the simplicity of culturing them, HOS cells provide a human cell alternative to NIH 3T3 murine fibroblasts for oncogene transfection studies.

Abstract
We reported earlier complete linkage between cystic fibrosis and an RFLP of the met proto-oncogene revealed by the probe pmetH. Another clone, pmetD, detects another polymorphism with the TaqI restriction enzyme. Further linkage studies, now involving 22 families, have confirmed the tight linkage of cystic fibrosis to the MET and D7S8 loci. Significant allelic association was found between CF and allelic series defined by the pmetH probe.

Abstract
Cystic fibrosis is a recessive genetic disorder, characterized clinically by chronic obstructive lung disease, pancreatic insufficiency and elevated sweat electrolytes; affected individuals rarely live past their early twenties. Cystic fibrosis is also one of the most common genetic diseases in the northern European population. The frequency of carriers of mutant alleles in some populations is estimated to be as high as 1 in 20, carrying a concomitant burden of about one affected child in 1,500 births. Because little is known of the essential biochemical defect caused by the mutant gene, a genetic linkage approach based on arbitrary genetic markers and family studies is indicated to determine the chromosomal location of the cystic fibrosis (CF) gene. We have now obtained evidence for tight linkage between the CF locus and a DNA sequence polymorphism at the met oncogene locus. This evidence, combined with the physical localization data for the met locus presented in the accompanying paper, places the CF locus in the middle third of the long arm of chromosome 7, probably between bands q21 and q31.

Abstract
The simian virus 40 (SV40) 72-base pair (bp) tandem-repeated sequences have a crucial role as an activator element in viral gene expression. We replaced the SV40 72-bp repeat with a 72-bp repeat derived from the long terminal repeat (LTR) of cloned Moloney murine sarcoma virus (MSV) DNA. Although there is no detectable sequence homology to SV40, the MSV repeats can substitute functionally for the SV40 repeats and generate a viable virus in monkey kidney cells.

Abstract
We describe the characterization of 34 hybrid lambda bacteriophages carrying EcoRI fragments obtained from DNA of defective interfering particles of the Patton strain of Herpes simplex virus type 1 (HSV-1). All cloned fragments contained S region terminal repeat sequences (TRs) fused to unique HSV-1 DNA. Several fragments contained deletions and rearrangements not described previously for DNA of HSV-1 defective interfering particles. A model describing the generation of defective interfering DNA based on recombination events involving the terminal "a" sequence as presented.

Abstract
Extrachromosomal DNA obtained from mink cells acutely infected with the Snyder-Theilen (ST) strain of feline sarcoma virus (feline leukemia virus) [FeSV(FeLV)] was fractionated electrophoretically, and samples enriched for FeLV and FeSV linear intermediates were digested with EcoRI and cloned in lambda phage. Hybrid phages were isolated containing either FeSV or FeLV DNA "inserts" and were characterized by restriction enzyme analysis, R-looping with purified 26 to 32S viral RNA, and heteroduplex formation. The recombinant phages (designated lambda FeSV and lambda FeLV) contain all of the genetic information represented in FeSV and FeLV RNA genomes but lack one extended terminally redundant sequence of 750 bases which appears once at each end of parental linear DNA intermediates. Restriction enzyme and heteroduplex analyses confirmed that sequences unique to FeSV (src sequences) are located at the center of the FeSV genome and are approximately 1.5 kilobase pairs in length. With respect to the 5'-3' orientation of genes in viral RNA, the order of genes in the FeSV genome is 5'-gag-src-env-c region-3'; only 0.9 kilobase pairs of gag and 0.6 kilobase pairs of env-derived FeLV sequences are represented in ST FeSV. Heteroduplex analyses between lambda FeSV or lambda FeLV DNA and Moloney murine sarcoma virus DNA (strain m1) were performed under conditions of reduced stringency to demonstrate limited regions of base pair homology. Two such regions were identified: the first occurs at the extreme 5' end of the leukemia and both sarcoma viral genomes, whereas the second corresponds to a 5' segment of leukemia virus "env" sequences conserved in both sarcoma viruses. The latter sequences are localized at the 3' end of FeSV src and at the 5' end of murine sarcoma virus src and could possibly correspond to regions of helper virus genomes that are required for retroviral transforming functions.

Abstract
This communication demonstrates further that terbium(III) can be used as a probe for DNA. The stoichiometry of terbium binding to DNA was measured by two new methods. In the first method, calf-thymus DNA was titrated with radioactive terbium-160, which is an isotope of the common terbium-159. The resulting DNA-terbium complex was trapped and measured on millipore filters. In the second method, a peak of UV absorption of terbium was found at 219 nm and was used to measure stocichiometry. By both methods, the stoichiometry of binding was one Tb(III) for each three available phosphate groups in DNA. Finally, a rapid method was developed using terbrium-160 to measure the amount of nucleic acid in a solution.

Abstract
This paper continues previous work on the analysis of nucleic acid-terbium complexes in the solid state. The fluorescence excitation and emission spectra of the RNA-terbium(III) complex is reported. The fluorescence excitation and emission spectra of both the RNA-terbium(III) and DNA-terbium(III) complexes as trapped on millipore filters is reported. One hundred percent of the DNA combined with terbium was trapped on millipore filters. Deoxyribonucleic acid was recovered from DNA-terbium(III) complexes trapped on millipore filters using SDS-extraction. Energy transfer was shown to occur from the bases in nucleic acids to the terbium ion, whereas the actual binding of terbium to nucleic acids was due to phosphate groups. The relative fluorescence of homopolyribonucleotide-terbium complexes showed that the guanine moiety was responsible for most of the observed fluorescence. Binding studies showed an equal affinity of radioactive terbium for all the homopolyribonucleotides. The fluorescence of solid-state DNA and RNA terbium complexes was used to measure picomole quantities of DNA or RNA.
