Histone Acetylation in Conjugating
We have monitored histone acetylation during conjugation of the ciliated protozoan Tetrahymena thermophila using antibodies against the tetraacetylated form of H4 histone (Pfeffer, U., N. Ferrari, and G. Vidali. 1986. J. Biol. Chem. 261:2496-2498). During meiosis, the three prezygotic divisions, fertilization, and the first postzygotic division, micronuclei, do not contain highly acetylated for...
متن کاملHistone acetylation increases chromatin accessibility.
In eukaryotes, the interaction of DNA with proteins and supramolecular complexes involved in gene expression is controlled by the dynamic organization of chromatin inasmuch as it defines the DNA accessibility. Here, the nuclear distribution of microinjected fluorescein-labeled dextrans of 42 kDa to 2.5 MDa molecular mass was used to characterize the chromatin accessibility in dependence on hist...
متن کاملHistone acetylation in gene regulation.
Genetic information is packaged in the highly dynamic nucleoprotein structure called chromatin. Many biological processes are regulated via post-translational modifications of key proteins. Acetylation of lysine residues at the N-terminal histone tails is one of the most studied covalent modifications influencing gene regulation in eukaryotic cells. This review focuses on the role of enzymes in...
متن کاملPlaying TAG with a Bacterial Stress Response
Tuberculosis is an age-old scourge of mankind. This chronic disease is caused by a bacterium, Mycobacterium tuberculosis, which sets up an initial infection in its victims’ lungs. Although the infection can spread to other organs, its most common symptoms are a painful and debilitating cough combined with difficulty breathing. Tuberculosis remains a major public health threat because even the b...
متن کاملPlaying Tag with Biomarkers of Glaucoma
An extraordinary faculty of world leaders converged in Toronto at the Glaucoma Risk and Disease Management Symposium on October 18 th , 2008, to discuss advances in our knowledge regarding predictors of glaucoma development and clinical course. The meeting opened with the 3 rd Research for Sight Keynote Lecture by Dr. Stanley Prusiner, Nobel Prize winner and innovator, who described his excitin...
