Implication

Randomized trial compares RNA extraction methods for assessing health in free-ranging cetaceans, suggesting improvements for stress biomarker identification.

Key Points

The aim is to develop robust methods for extracting high-quality RNA from cetacean blubber for health assessments.
Subsampled blubber biopsies from wild bottlenose dolphins during health assessments.
Compared preservation, homogenization, and extraction methods on RNA yield and integrity.
Utilized phenol–guanidine–chloroform and silica spin column kit designed for fatty tissues.
Flash-freezing, cryogenic milling, and bead beating improved RNA integrity values up to 8.3.
The optimized extraction method produced large yields of intact RNA suitable for stress biomarker discovery.
RNA quality exceeded previously reported metrics, enhancing health assessment capabilities for wild cetaceans.
