Insertions of transposon Tn5 into ribosomal protein PNA polymerase operons.

Hui, I, Maltman, K, Little, R, Hastrup, S, Johnsen, M, Fiil, N, ...

The genetic organization and interrelationships between the two ribosomal protein transcription units (the L11 and L10 operons) from near 89 min on the Escherichia coli chromosome were studied by...

JINN, an integrated software package for molecular geneticists.

Johnsen, M

I describe JINN, a microcomputer-based system designed to maintain and search a strain collection, to enter, modify and analyze sequences, and to use the EMBL Sequence Data Base. The major objective...

Transcription factor PEA3 participates in the induction of urokinase plasminogen activator transcription in murine keratinocytes stimulated with epidermal growth factor or phorbol-ester.

Rørth, P, Nerlov, C, Blasi, F, Johnsen, M

Keratinocytes in culture represent cells which exhibit continued and controlled growth in the organism. We have investigated the synthesis of urokinase plasminogen activator mRNA in exponentially...

A transforming ras gene can provide an essential function ordinarily supplied by an endogenous ras gene.

Papageorge, A G, Willumsen, B M, Johnsen, M, Kung, H F, Stacey, D W, Vass, W C, ...

Microinjection of monoclonal antibody Y13-259, which reacts with all known mammalian and yeast ras-encoded proteins, has previously been shown to prevent NIH 3T3 cells from entering the S phase (L....

Mutational analysis of a ras catalytic domain.

Willumsen, B M, Papageorge, A G, Kung, H F, Bekesi, E, Robins, T, Johnsen, M, ...

We used linker insertion-deletion mutagenesis to study the catalytic domain of the Harvey murine sarcoma virus v-rasH transforming protein, which is closely related to the cellular rasH protein. The...

Autogenous control: ribosomal protein L10-L12 complex binds to the leader sequence of its mRNA.

Johnsen, M, Christensen, T, Dennis, P P, Fiil, N P

Ribosomal proteins L10 and L12 are encoded in the L10 operon, situated at position 89.5 min on the Escherichia coli genetic map, and are able to regulate their own translation. The two proteins form...

A novel complex between the p65 subunit of NF-kappa B and c-Rel binds to a DNA element involved in the phorbol ester induction of the human urokinase gene.

Hansen, S K, Nerlov, C, Zabel, U, Verde, P, Johnsen, M, Baeuerle, P A, ...

The NF-kappa B subunits, p50 and p65, have extensive sequence homology with the c-rel proto-oncogene and the Drosophila morphogen dorsal. It has recently been shown that in vitro translated c-Rel can...

A regulatory element that mediates co-operation between a PEA3-AP-1 element and an AP-1 site is required for phorbol ester induction of urokinase enhancer activity in HepG2 hepatoma cells.

Nerlov, C, De Cesare, D, Pergola, F, Caracciolo, A, Blasi, F, Johnsen, M, ...

We have characterized a transcriptional enhancer of the human urokinase-type plasminogen activator (uPA) gene and found a regulatory element required for co-operation between a PEA3--AP-1 element and...

RNA secondary structure and translation inhibition: analysis of mutants in the rplJ leader.

Christensen, T, Johnsen, M, Fiil, N P, Friesen, J D

We have carried out measurements of the stable binding of the ribosomal protein (r-protein) complex L10-L7/L12 to mutant forms of the mRNA leader of the rplJ operon of Escherichia coli. One of the...

Service delivery and community: social capital, service systems integration, and outcomes among homeless persons with severe mental illness.

Rosenheck, R, Morrissey, J, Lam, J, Calloway, M, Stolar, M, Johnsen, M, ...

OBJECTIVES: This study evaluated the influence of features of community social environment and service system integration on service use, housing, and clinical outcomes among homeless people with...

Service system integration, access to services, and housing outcomes in a program for homeless persons with severe mental illness.

Rosenheck, R, Morrissey, J, Lam, J, Calloway, M, Johnsen, M, Goldman, H, ...

OBJECTIVES: This study evaluated the hypothesis that greater integration and coordination between agencies within service systems is associated with greater accessibility of services and improved...
