A New Epigenetic Crosstalk: Chemical Modification Information Flow

Chemical modification of maridomycin, a new macrolide antibiotic.

Maridomycin, a new macrolide antibiotic, and tetrahydromaridomycin were acylated into their mono, di, and tri acyl derivatives. These derivatives were compared with the parent antibiotic, maridomycin, for their (i) in vitro antimicrobial activities, (ii) protective effect in mice infected with Staphylococcus aureus (oral administration), (iii) blood levels attained in rats, and (iv) acute toxic...

Crosstalk among Epigenetic Pathways Regulates Neurogenesis

The process of neurogenesis includes neural stem cell proliferation, fate specification, young neuron migration, neuronal maturation, and functional integration into existing circuits. Although neurogenesis occurs largely during embryonic development, low levels but functionally important neurogenesis persists in restricted regions of the postnatal brain, including the subgranular zone of the d...

Epigenetic crosstalk: a molecular language in human metabolic disorders.

Technological breakthroughs are emphasizing the impact of epigenetic mechanisms in human health highlighting the importance of a fine-tune orchestration of DNA methylation, micro RNAs, histone modifications, and chromatin structure. Transcriptional regulators sense the concentration of intermediary metabolites associated to a wide variety of biological processes including the long-term imprinti...

Epigenetic Modification of Plant Chromatin

Based on the analysis of 20 different monocot and eudicot species, we propose that the centromeric distribution of the phosphorylated histone H2AThr120 is evolutionary highly conserved across species with monoand holocentric chromosomes. Therefore, antibodies recognizing the phosphorylated threonine 120 of the histone H2A can serve as a universal marker for the cytological detection of centrome...
