Discovery: How Colorado Potato Beetles Beat Pesticides

New research shows that pesticide alter how Colorado potato beetles manage their DNA. These changes were passed down two generations suggesting that rapid resistance to pesticides may not require beetles to evolve their genetic code. Instead they may simply use existing genes to tolerate toxins already found in potatoes. The scientists were surprised that these epigenetic changes, triggered by a single tiny dose of pesticide, were maintained through multiple rounds of sexual reproduction.

Epigenetic Changes in ADNP Syndrome, a Cause of Autism, Do Not Indicate Profound Presentation of the Disorder

A study led by the Seaver Autism Center for Research and Treatment at Mount Sinai found that two different blood epigenetic signatures associated with ADNP syndrome (also known as Helsmoortel-Van Der Aa syndrome) have only a modest correlation with clinical manifestations of the syndrome.

Hackensack Meridian CDI Scientists Uncover Signposts in DNA that Pinpoint Risks for Cancers and other Diseases

The most strongly disease-relevant genetic variants can be hard to localize in widespread scanning of the genome – but by zooming in on key genetic locations associated with these DNA methylation imbalances in multiple normal and cancer tissues, the scientists report they have uncovered promising new leads beneath the broader statistical signals.

NEI researchers link age-related DNA modifications to susceptibility to eye disease

National Eye Institute (NEI) researchers profiling epigenomic changes in light-sensing mouse photoreceptors have a clearer picture of how age-related eye diseases may be linked to age-related changes in the regulation of gene expression. The findings, published online April 21 in Cell Reports, suggest that the epigenome could be targeted as a therapeutic strategy to prevent leading causes of vision loss, such as age-related macular degeneration (AMD).

New drug target for prostate cancer found in the non-coding genome

Scientists at Princess Margaret Cancer Centre have identified the drivers of a crucial gene involved in prostate cancer, revealing new targets for drug design.

Researchers identified a set of cis-regulatory elements – namely enhancers and the promoter – in the non-coding region of the genome, which affect the expression of FOXA1 gene, one of the major drivers or oncogenes involved in prostate cancer development.
