Accurate and Efficient Detection of Nasopharyngeal Carcinoma Using Multi‐Dimensional Features of Plasma Cell‐Free DNA

Head &Neck, EarlyView.
ABSTRACT Background The incidence of Nasopharyngeal carcinoma (NPC) is rising in recent years, especially in some non‐developed parts of the world. Hence, cost‐efficient means for sensitive detection of NPC are vital. Methods We recruited 646 participants, including healthy individuals, patients with benign nasopharyngeal diseases, and NPC patients for

Statistical mechanics of nucleosome ordering by chromatin structure-induced two-body interactions

, 2011
One-dimensional arrays of nucleosomes (DNA-bound histone octamers separated by stretches of linker DNA) fold into higher-order chromatin structures which ultimately make up eukaryotic chromosomes.

A hitchhiker's guide to single‐cell epigenomics: Methods and applications for cancer research

International Journal of Cancer, EarlyView.
Abstract Genetic mutations are well known to influence tumorigenesis, tumor progression, treatment response and relapse, but the role of epigenetic variation in cancer progression is still largely unexplored. The lack of epigenetic understanding in cancer evolution is in part due to the limited availability of methods to examine such a heterogeneous ...

The influence of the cylindrical shape of the nucleosomes and H1 defects on properties of chromatin [PDF]

, 2007
We present a model improving the two-angle model for interphase chromatin (E2A model). This model takes into account the cylindrical shape of the histone octamers, the H1 histones in front of the nucleosomes and the vertical distance $d$ between the in ...

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

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.

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 ...

ATP-dependent chromatosome remodeling [PDF]

, 2008
Chromatin serves to package, protect and organize the complex eukaryotic genomes to assure their stable inheritance over many cell generations. At the same time, chromatin must be dynamic to allow continued use of DNA during a cell's lifetime.

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.

RepliChrom: Interpretable machine learning predicts cancer‐associated enhancer‐promoter interactions using DNA replication timing

iMeta, EarlyView.
RepliChrom is an interpretable machine learning model that predicts enhancer‐promoter interactions using DNA replication timing across multiple cell types. By integrating replication timing with chromatin interaction data from multiple experimental platforms, it accurately distinguishes true interactions and reveals promoter‐region signals as key ...
