Gene Regulation: Implications of Histone Dispersal Patterns for Epigenetics

نویسنده

  • Nicole J. Francis
چکیده

Histones are widely believed to carry regulatory information across cell generations. A recent study suggests limits to this model by measuring dispersal of ancestral histones in yeast.

اپی‌ژنتیک سرطان پستان: مقاله مروری

Stable molecular changes during cell division without any change in the sequence of DNA molecules is known as epigenetic. Molecular mechanisms involved in this process, including histone modifications, methylation of DNA, protein complex and RNA antisense. Cancer genome changes happen through a combination of DNA hypermethylation, long-term epigenetic silencing with heterozygosis loss and genom...

Dispersal patterns of endogenous bacteria among grass carp (Ctenopharyngodon idellus) guts

The formation and regulation of vertebrate endogenous intestinal microbiota has been widely studied as the microbiota plays a crucial role in the host nutrition, development, and health. Despite the importance of microbiota for host health, it is still unclear whether the endogenous intestinal microorganisms are genetically distinct or whether they are genetically related with each other in dif...

O-5: Reprogramming of Paternal DNA Methylome during Spermiogenesis

Background Chromatin of male and female gametes undergoes a number of reprogramming events during the transition from germ cell to embryonic developmental programs in the zygote. This process involves reorganisation of the patterns of 5-methylcytosine (5mC), a DNA modification associated with regulation of gene activity. Notably, both maternal and paternal genomes undergo Tet3-dependent oxidati...

درمان سرطان بر پایه اپی ژنتیک

Introduction: Epigenetics involves the study of heritable changes in the regulation of gene activity and expression that are not dependent on gene sequence. Main mechanisms of epigenetic modifications are DNA methylation, Histone modification and Nucleosome positioning. Several studies have shown that these modifications are related to cancer initiation, progression or tumor metastasis. In cont...
