Histological and Gene Expression Analyses of the Arm and Finger Macroglands of Two Hyloxalus Frogs (Dendrobatidae)

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Chemical communication during courtship is well documented in salamanders and newts, but its role in frogs is less understood. In some Neotropical poison frogs, males exhibit specialised mucous glands (SMGs) in the hand integument that express high levels of sodefrin precursor‐like factors (SPFs), an amphibian pheromone. Some species also show

Impact of Pre‐Treatment Serum Ferritin on Response and Survival in Myelodysplastic Syndromes Treated With Azacytidine: A Multivariate Analysis

Cancer Medicine, Volume 14, Issue 15, August 2025.
Elevated serum ferritin levels before treatment with azacytidine are associated with lower response rates and shorter survival in patients with myelodysplastic syndromes. This study supports the early identification of transfusion‐related iron overload to improve treatment planning.

Programmed cell death pathways coordinate neutrophil and macrophage clearance in zebrafish and are differentially exploited by Salmonella Typhimurium

Cell Death and Disease
Programmed cell death (PCD) is essential for immune cell homeostasis and host defense, yet its role in neutrophil and macrophage elimination during bacterial infections remains poorly understood.

Vitamin D deficiency induces erectile dysfunction: Role of superoxide and Slpi

British Journal of Pharmacology, Volume 182, Issue 15, Page 3669-3687, August 2025.
Background and Purpose Epidemiological studies suggest a relationship between vitamin D deficiency and erectile dysfunction (ED). We hypothesized that vitamin D deficiency or vitamin D receptor (VDR) knockout causes ED and analysed the underlying molecular mechanisms.

Deciphering opening mechanisms of 14‐3‐3 proteins

Protein Science, Volume 34, Issue 4, April 2025.
Abstract The 14‐3‐3 proteins are a highly conserved family of regulatory molecules that play crucial roles in various cellular processes. They are known for their ability to bind to phosphorylated serine and threonine residues on target proteins, which allows them to modulate their activity, localization, and stability.
