Navigating Past Oceans: Comparing Metabarcoding and Metagenomics of Marine Ancient Sediment Environmental DNA

Molecular Ecology Resources, EarlyView.
ABSTRACT The condition of ancient marine ecosystems provides context for contemporary biodiversity changes in human‐impacted oceans. Sequencing sedimentary ancient DNA (sedaDNA) is an emerging method for generating high‐resolution biodiversity time‐series data, offering insights into past ecosystems.

Designing Epigenetic Clocks for Wildlife Research

Molecular Ecology Resources, EarlyView.
ABSTRACT The applications of epigenetic clocks – statistical models that predict an individual's age based on DNA methylation patterns – are expanding in wildlife conservation and management. This growing interest highlights the need for field‐specific design best practices.

Independent Avian Epigenetic Clocks for Ageing and Development

Molecular Ecology Resources, EarlyView.
ABSTRACT Information on individual age is a fundamental aspect in many ecological and evolutionary studies. However, accurate and non‐lethal methods that can be applied to estimate the age of wild animals are often absent. Furthermore, since the process of ageing is accompanied by a physical decline and the deterioration of biological functions, the ...

BRCA1 Promoter Methylation in Ovarian Cancer: Clinical Relevance and a Novel Diagnostic Approach Using Fragment Analysis

Cancer Science, EarlyView.
With the aim of clinical applications, we established a simplified evaluation method for BRCA1 methylation using fragment analysis, called BRCA1‐FAM. We confirmed that high‐grade serous ovarian cancer patients with BRCA1 methylation had poor prognosis.
