The new sex-determiner may be linked with genes experiencing sexually antagonistic selection.
Histone H3 lysine-4 (H3K4) methylation is linked with gene activation (Bhaumik et al, 2007).
Furthermore, epigenetic changes including histone modifications are increasingly being linked with gene dysregulation and cellular responses induced by air pollutants, including ambient PM [ 8].
Researchers from a recent study also reported that feeding adult male rats a high-fat diet led to insulin resistance in female offspring that was associated with β cell dysfunction, and this was linked with gene hypomethylation [ 89].
The first is linked with genes coding for proteins typically involved in the Calvin-Benson cycle, such as phosphoribulokinase (prk), whereas the second is associated with two genes (cbbO and cbbQ) that encode Rubisco activation proteins.
Familial forms of the neurodegenerative diseases amyotrophic lateral sclerosis (ALS) and frontotemporal disease (FTD) have previously been linked with genes encoding FUS and TDP-43, although the molecular mechanisms underlying this association were previously unclear.
MLLs (mixed lineage leukaemia histone methylases) are human HMTs, such as MLL1, MLL2, MLL3 and MLL4 that specifically methylate histone H3K4 (H3 at lysine 4) and are linked with genes [ 7].
To date, notable changes in transcription have been linked with genes involved in energy and fuel utilization processes, such as cell growth, glycolysis, lipid metabolism, molecular transport, and cellular stress response (e.g., unfolded protein response, apoptosis, cell cycle arrest, and antioxidant defense) [2,3,5 7].
Although aberrant methylation in gene promoter regions is known to be linked with altered gene expression, the effect of hypermethylation in the gene body is unclear and inconclusive [ 39].
