Current status of genome‐wide epigenetic profiling of mammalian preimplantation embryos
Abstract Background Genome‐wide information on epigenetic modifications in mammalian preimplantation embryos was an unexplored sanctuary of valuable research insights protected by the difficulty of its analysis. However, that is no longer the case, and many epigenome maps are now available for sightseeing there.

Gut bacterial profiles in Parkinson's disease: A systematic review
The role of gut bacteria in association with Parkinson's disease (PD) may involve the alterations of bacteria with the capacity to produce short‐chain fatty acids (SCFAs) and an increase in putative pathobionts, which may work together to potentially impair the intestinal barrier and/or blood–brain barrier integrity, stimulating systemic and neural ...

The molecular mechanisms of epigenetic regulation in gastric cancer development are not yet well established. In this study, we demonstrated that KMT2A was highly expressed in gastric cancer and associated with poor outcomes of patients and revealed that

Evolution, or Epigenesis? [PDF]
IN the English translation of Prof. Hertwig's book “The Cell,” it is stated (p. 295), “When the female gamete of the Alga Ectocarpus comes to rest, for a few minutes it becomes receptive. If the egg is not fertilised at this time … parthenogenetic germination begins to make its appearance … It may be accepted as a law of nature (italics mine) for ...

The modern versus extended evolutionary synthesis : sketch of an intra-genomic gene's eye view for the evolutionary-genetic underpinning of epigenetic and developmental evolution [PDF]
Studying the phenotypic evolution of organisms in terms of populations of genes and genotypes, the Modern Synthesis (MS) conceptualizes biological evolution in terms of 'inter-organismal' interactions among genes sitting in the different individual ...

The Number of Different Binary Functions Generated by NK-Kauffman Networks and the Emergence of Genetic Robustness [PDF]
We determine the average number $ \vartheta (N, K) $, of \textit{NK}-Kauffman networks that give rise to the same binary function. We show that, for $ N \gg 1 $, there exists a connectivity critical value $ K_c $ such that $ \vartheta(N,K) \approx e ...

On the hodological criterion for homology
Owen’s pre-evolutionary definition of a homologue as the same organ in different animals under every variety of form and function and its redefinition after Darwin as the same trait in different lineages due to common ancestry entail the same heuristic ...
