Epigenomics‐guided precision oncology: Chromatin variants in prostate tumor evolution
International Journal of Cancer, EarlyView.Abstract Prostate cancer is a common malignancy that in 5%–30% leads to treatment‐resistant and highly aggressive disease. Metastasis‐potential and treatment‐resistance is thought to rely on increased plasticity of the cancer cells—a mechanism whereby cancer cells alter their identity to adapt to changing environments or therapeutic pressures to create

DNA accessibility of chromatosomes quantified by automated image analysis of AFM data
Scientific Reports, 2019 DNA compaction and accessibility in eukaryotes are governed by nucleosomes and orchestrated through interactions between DNA and DNA-binding proteins.

Journal of Biomedical Science, 2011 Background Colorectal carcinoma is a common and often fatal disease in which methods of early detection and monitoring are essential. The present study was conducted for measuring serum levels of nucleosomes, carcinoembryonic antigen (CEA) and CA 19-9 in

Chromatin: The nucleosome unwrapped [PDF]
Current Biology, 1997 The structure of the nucleosome core particle has been determined by X-ray crystallography at 2.8 A resolution. The structure has several significant surprises, and provides important new insights into the structure and function of chromatin.

Enhancer‐dependent gene regulation in space, time, and malignancies
International Journal of Cancer, EarlyView.Abstract Control of cell‐type‐specific gene activation requires the coordinated activity of distal regulatory elements, including enhancers, whose inputs must be temporally integrated. Dysregulation of this regulatory capacity, such as aberrant usage of enhancers, can result in malignant transformation of cells.

A study of strong nucleosomes in the human genome
iScience, 2022 Summary: Micrococcal nuclease (MNase) is widely used to map nucleosomes. However, nucleosomes are highly dynamic and susceptible to experimental conditions, resulting in extreme variability across nucleosome maps, which complicates the generation of ...

Therapeutic targeting of chromatin alterations in leukemia and solid tumors
International Journal of Cancer, EarlyView.Abstract Alterations in chromatin conformation and post‐translational modification of histones have become increasingly recognized as critical drivers of cancer development, progression, and therapy resistance. Recent advances in drug development have led to the establishment of several highly selective small molecule inhibitors, several of which are ...

Epigenetic reprogramming in multiple myeloma—Challenges and opportunities
International Journal of Cancer, EarlyView.Abstract In cancer, mutational processes act in concert with epigenetic reprogramming to endow malignant cells with hallmark properties that underpin tumorigenesis. Compared with the relatively rigid and slow processes of genetic evolution, the plastic nature of chromatin enables cells to adapt to a changing environment more rapidly.
