Histone deacetylation epigenetically turns cells that protect cancer into ones that kill cancer

Histone Deacetylation Turns Cancer-Protecting Cells into Cancer-Killing Cells

September 29, 2015 Bailey Kirkpatrick

A significant advancement in cancer research was presented in a recent study conducted by scientists from Cornell University, University of Chicago, and Houston Methodist Hospital. The researchers demonstrated that a specific protein known as a cell surface receptor can cause immune cells to attack malignant tumors as opposed to protecting them via an epigenetic mechanism known as histone deacetylation. The research was published in Nature Communications. CD4+ T-cells, also known as CD4 or helper T-cells, are crucial to the immune [more…]

DNA methylation and bisulfite conversion affect oil palm fruit production

DNA Methylation and ‘Bad Karma’ To Blame for Oil Palm Trees’ Useless Fruit

September 22, 2015 Bailey Kirkpatrick

“Bad karma” and epigenetics are to blame for the spoiling of tens of thousands of young oil palms grown at large plantations in Southeast Asia, particularly Malaysia, according to a group of researchers at the Cold Spring Harbor Laboratory. Not only have millions of dollars been wasted on these plants, also known as African oil palm or Elaeis guineensis, but the tropical environment has suffered as a result of some faulty epigenetic machinery. Researchers utilized bisulfite conversion and microarrays to [more…]

Short-Term Sleep Loss Alters DNA Methylation of Clock Genes

September 15, 2015 Bailey Kirkpatrick

Sleep is crucial to our well-being and helps in the process of learning and memory formation. Without proper sleep we can feel moody, irritable, and have difficulty solving problems. We can even be less creative when we don’t get enough sleep. Now, research published in the Journal of Clinical Endocrinology and Metabolism is showing us that just one night of poor sleep can lead to epigenetic changes to our DNA, specifically to our “clock genes” which control our circadian clock. [more…]

Histone Modifications could Reverse Aging

Histone Modifications and Epigenetic Regulation Could Hold the Key to Reversing Aging

September 8, 2015 Bailey Kirkpatrick

Epigenetics has numerous connections to the process of aging, research hinting at the association between longevity and factors such as transcriptome length and DNA methylation patterns. Clearly, understanding the molecular controls of aging proves to be an intriguing endeavor as we try to interpret the clues of how we might slow down and perhaps even reverse aging. Although research has a long way to go before we can expect anything akin to a fountain of youth, studies are offering new [more…]

Diabetes and Mitochondrial DNA Methylation

Mitochondrial DNA Methylation Gives Clues to Insulin Response in Pre-Diabetics

September 1, 2015 Bailey Kirkpatrick

What if those who are resistant to insulin but don’t have diabetes could help prevent themselves and others from developing the disease? Researchers from Virginia Tech have discovered a biomarker in those who are pre-diabetic that could prevent them and potentially others from getting type 2 diabetes. The researchers uncovered that pre-diabetics, or people who are at high risk of developing type 2 diabetes, who do not respond to insulin had altered DNA in their mitochondria and had an increased [more…]
