Acetylation of lysine residues on the histone tails isdirectly involved in regulation of gene transcription. Already in 1964, it was shown that histone binding to DNA-inhibited gene transcription. In addition, it was shown that chemical acetylation of histones could reduce this inhibiting effect [6]...
Histone acetylation regulates gene expression. Whether this is caused by a general increase in nucleosome fluidity due to charge neutralization or by a more specific code is still matter of debate. By using a set of glucose-repressed Adr1-dependent genes of Saccharomyces cerevisiae , whose transcrip...
H4 acetylation does not replace H3 acetylation in chromatin remodelling and transcription activation of Adr1-dependent genes. Mol Microbiol. 2006;62:1433-46. https://doi.org/10.1111/j.1365-2958.2006.05451.x.Agricola, E., L. Verdone, E. Di Mauro, and M. Caserta. 2006. H4 ...
Please explain the consequence of x chromosome inactivation in terms of the proteins encoded by the x chromosome genes. What is a genome in the perspective of genetics? (a) What is histone? (b) How does the acetylation of histone proteins affect gene activity near the acetylation? DNA methyla...
Third, the placenta and decidua also responded to LPS, but qualitatively differently from the maternal lung and liver. Genes responded mainly at a single timepoint: the largest change occurred at 5 h (Fig.1B). Notably, decidual and placental LPS vs. Ctrl responses were overall similar (Fig...
However, in the prevention and the treatment of cardiovascular diseases, the daily dosage generally amounts to 75–150 mg (in some cases, up to 325 mg/d).4 The basic mechanism of the ASA effect is nonenzymatic protein modification – acetylation – which results in cyclooxygenase (COX) ...
The impact of spaceflight on the immune system has been investigated extensively during spaceflight missions and in model experiments conducted on Earth. Data suggest that the spaceflight environment may affect the development of acquired immunity, and i
[46], a sole constitutive overexpression of Lin28A in these cells was not sufficient to drive brain tumor development, neither in the forebrain nor hindbrain. In line with these findings, Lin28A alone was not sufficient to constantly activate Shh and Wnt signaling in vivo. Still, Lin28A ...

The human immunodeficiency virus type 1 (HIV-1) trans-activator of transcription protein Tat is an important factor in viral pathogenesis. In addition to its function as the key trans-activator of viral transcription, Tat is also secreted by the infected
