Stage-specific transcriptomic and DNA methylation responses to triploidy in European sea bass embryos and larvae

BMC Genomics
Background Polyploidy, the condition of having more than two chromosome sets, is relatively common in plants but rare in animals, largely due to reproductive challenges associated with altered chromosome numbers.

Dynamic epimarks in sex-related genes predict gonad phenotype in the European sea bass, a fish with mixed genetic and environmental sex determination

Epigenetics, 2018
The integration of genomic and environmental influences into methylation patterns to bring about a phenotype is of central interest in developmental epigenetics, but many details are still unclear.

Sphingosine‐1‐Phosphate Receptor 1 Promotes Ovarian Cancer Tumorsphere Proliferation and Metastasis

International Journal of Cancer, EarlyView.
In high‐grade serous ovarian cancer, malignant ascites frequently arise as ovarian cancer cells shed from the primary tumor and aggregate into tumorspheres, severely limiting treatment success. To date, little is known about the mechanisms governing tumorsphere endurance and metastasis within the ascites once formed.

Non‐Stationary Dry‐Spell Hazard Probabilities for Spain

International Journal of Climatology, EarlyView.
This study assesses long‐term changes in dry‐spell hazard probabilities across Spain (1961–2024) using a novel non‐stationary extreme value framework applied to daily precipitation records from a dense observational network. Results show that dry‐spell duration and associated return levels are dominantly stationary, with non‐stationary models providing

Astragalus ecomorphology in Quaternary elephantids

Journal of Quaternary Science, EarlyView.
ABSTRACT The astragalus plays a fundamental role in the graviportal locomotion of proboscideans, reflecting the biomechanical constraints imposed by large body masses. This study analyses the morphological variability of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...
