Researchers probe RNA epigenetics and chromatin structures to predict drug resistance in leukemia

Drug resistance is a major obstacle to effective treatment for patients with cancer and leukemia. Epigenetic modifying drugs have been proven effective for some patients with hematologic malignancies, such as myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML).

Porvair Sciences launches new ChIP-Seq library preparation kit

Porvair Sciences announces the launch of UniqSeq - a new ChIP-Seq library preparation kit. High-quality library preparation is key to a successful ChIP-Seq experiment. Obtaining complex libraries with good coverage and low bias are just some of the features that depend on high-quality DNA after performing ChIP assays.

Study findings establish basis for epigenetic link between aging and Alzheimer's disease

Although certain genetic variants increase the risk of Alzheimer's disease (AD), age is the strongest known risk factor. But the way in which molecular processes of aging predispose people to AD, or become impaired in AD remains a mystery.

Researchers discover new interaction mechanism of unstructured proteins

Proteins are among the most important biomolecules and are the key mediators of molecular communication between and within cells. For two proteins to be able to bind, specific regions of their three-dimensional structure have to exactly match one another - like a key that fits into a lock.

Penn study sheds new light on immune cell identity

Almost all cells in the human body have identical DNA sequences, yet there are 200-plus cell types with different sizes, shapes, and chemical compositions. Determining what parts of the genome are read to make protein and which are silenced is orchestrated by proteins called transcription factors.

Researchers target abnormal epigenetic mechanisms involved in childhood cancers

Several childhood cancer cell types show features of immature neural cells, and there is evidence suggesting that these tumors may arise from neural crest stem cells that underwent abnormal changes during embryonic development.

Researchers propose new regulation mechanism linked to action of SirT6 on chromatin

Researchers from the Epigenetics and Cancer Biology Program of the Bellvitge Biomedical Research Institute, led by Dr. Àlex Vaquero, have proposed a new regulation mechanism of the NF-κB pathway, which is associated with accelerated cellular aging, based on the analysis of the function of the SirT6 protein.

Research suggests genome's spatial organization as important switch for defining cell types

During differentiation of pluripotent stem cells to cardiomyocytes, the three-dimensional folding of the DNA reorganizes itself. This reorganization of the DNA architecture precedes and defines important epigenetic patterns.
