Dihydrotestosterone as a selective cellular/nuclear localization vector for anti-gene peptide nucleic acid in prostatic carcinoma cells
Autor: L C, Boffa, S, Scarfi, M R, Mariani, G, Damonte, V G, Allfrey, U, Benatti, P L, Morris
Publikováno v: Cancer research. 60(8)
Peptide nucleic acids (PNAs) are synthetic structural analogues of DNA and RNA that, if allowed to enter the cell, bind to the complementary polynucleotide sequence and inhibit DNA transcription and mRNA translation. Although PNAs have a very limited

Publikováno v: Oncology research. 9(1)
A peptide nucleic acid (PNA) complementary to a unique DNA sequence in the second exon of the human myc proto-oncogene was tested for its effects on transcription in colonic adenocarcinoma cells in which myc had been amplified and rearranged. A promi

Recovery of transcriptionally active chromatin restriction fragments by binding to organomercurial-agarose magnetic beads. A rapid and sensitive method for monitoring changes in higher order chromatin structure during gene activation and repression

Publikováno v: The Journal of biological chemistry. 268(31)
The unfolding of nucleosomes along transcriptionally active DNA sequences uncovers previously shielded cysteinyl-thiol groups of histone H3 molecules located at the center of the nucleosome core. This change in conformation and SH reactivity of nucle

Nucleosome structural changes during derepression of silent mating-type loci in yeast
Autor: T A, Chen-Cleland, M M, Smith, S, Le, R, Sternglanz, V G, Allfrey
Publikováno v: The Journal of biological chemistry. 268(2)
Mutant a and alpha yeast cells were created with histone H3 containing cysteine in place of alanine 110. Because transcriptionally active nucleosomes "unfold" to reveal the histone H3-thiol groups at the center of the core, the active nucleosomes of

Nucleosome fractionation by mercury affinity chromatography. Contrasting distribution of transcriptionally active DNA sequences and acetylated histones in nucleosome fractions of wild-type yeast cells and cells expressing a histone H3 gene altered to encode a cysteine 110 residue
Autor: T A, Chen, M M, Smith, S Y, Le, R, Sternglanz, V G, Allfrey
Publikováno v: The Journal of biological chemistry. 266(10)
A technique for the separation of transcriptionally active and inactive nucleosomes by mercury affinity chromatography has been applied to study the nucleosomal distribution of DNA sequences from the GAL1, ACT1, HIS4, MAT alpha, and HMRa genes of yea

Affinity chromatography of mammalian and yeast nucleosomes. Two modes of binding of transcriptionally active mammalian nucleosomes to organomercurial-agarose columns, and contrasting behavior of the active nucleosomes of yeast
Autor: J, Walker, T A, Chen, R, Sterner, M, Berger, F, Winston, V G, Allfrey
Publikováno v: The Journal of biological chemistry. 265(10)
The reasons for the selective binding of nucleosomes from transcriptionally active genes to the organomercurial-agarose columns have been investigated. At least two modes of binding are identified by a new two-stage elution procedure that discriminat

Publikováno v: Proceedings of the National Academy of Sciences. 79:4589-4593
African green monkey CV-1 cells infected with simian virus 40 (SV40) were incubated in the presence of sodium [35S]thiophosphate. The viral DNA was prepared and the newly synthesized SV40 DNA molecules containing phosphorothioate groups were selectiv
