Background: Nucleosome repositioning in cancer is believed to cause many changes in genome organisation and gene expression. Understanding these changes is important to elucidate fundamental aspects of cancer. It is also important for medical diagnostics based on cell-free DNA (cfDNA), which originates from genomic DNA regions protected from digestion by nucleosomes.

With only 13.75% of the identified Aboriginal and Torres Strait Islander population of northern Queensland accessing a billed 715 Health Assessment over a 12-month period, Northern Queensland Primary Health Network (NQPHN) is embarking on an ambitious 12-month program to dramatically improve access to health assessments, and integrated and coordinated care for First Nations' people within its region. By supporting primary care providers with targeted education, training, and digital health literacy bundles and tools, NQPHN aims to facilitate quality and culturally safe 715 Health Assessments to manage chronic conditions.

Here, we aimed to characterise and track patient-specific somatic ctDNA variants, to assess longitudinal changes in disease burden and explore the landscape of actionable alterations.
Methods: We followed 3 patients with resectable disease and 4 patients with unresectable disease, including 4 patients with ≥ 3 serial follow-up samples, of whom 2 were rare long survivors (> 5 years).
The mammalian epigenome contains thousands of heterochromatin nanodomains (HNDs) marked by di- and trimethylation of histone H3 at lysine 9 (H3K9me2/3), which have a typical size of 3-10 nucleosomes. However, what governs HND location and extension is only partly understood. Here, we address this issue by introducing the chromatin hierarchical lattice framework (ChromHL) that predicts chromatin state patterns with single-nucleotide resolution.
