A novel lncRNA (Ephemeron) is connected to known post-transcriptional and epigenetic regulators as part of an integrated machinery, which controls the timely exit from the naïve state of mouse embryonic stem cells.
A pathway directed by the KRAS oncoprotein leads to aberrant hypermethylation and transcriptional silencing of many genes including tumor suppressors, thereby promoting tumor development.

The maintenance DNA methyltransferase DNMT1 is required for the transition of spermatogonia to spermatocytes both during larval testis development and adult sperm replenishment in the insect Oncopeltus fasciatus.
Cell-specific alternative splicing of the synaptic calcium channel gene Cacna1b is controlled by exon hypomethylation and CTCF binding and is disrupted following nerve injury.
Alterations of DNA methylation were associated with articular cartilage degeneration in hemophilic arthropathy, and aberrant methylation and expression of TNXB promote blood-induced chondrocyte apoptosis by regulating AKT activation.

Two methyl-binding domain proteins have interdependent functions in embryonic stem cells, and this interdependency extends to the DNA methylation/hydroxymethylation machinery.
Bioinformatics analyses reveal that the Krüppel-associated box domain zinc finger proteins are associated with DNA methylation of retroelements in human primordial germ cells which highlight potential molecular mechanisms for the regulation of retroelements in human male germ cells.
Cell lineage tracing and biochemical analysis of cell fate during murine stem cell differentiation demonstrates a specific cooperativity between perturbations in histone methylation and eroded telomeres that destabilize cell differentiation.

Astyanax mexicanus surface-dwelling fish exposed to complete darkness develop many traits resembling cavefish adaptations by phenotypic plasticity in a single generation.
