Reproductive biology of the endangered percid Zingel asper in captivity: a histological description of the male reproductive cycle

Folia Histochemica et Cytobiologica, 2011
The endemic Rhodanian percid Zingel asper (Linnaeus, 1758), is usually found throughout the Rhônebasin, but this fish is now in sharp decline. Understanding its reproductive physiology is important so as to be ableto artificially control its reproduction

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

THE REPRODUCTIVE CYCLE OF SPHAERIUM SIMILE

The Biological Bulletin, 1973
1. Reproduction occurs throughout the year in S. simile although definite variations can be observed in different reproductive activities at different times. 2. Gametogenesis and mature gametes are visible to some extent during the fall, winter and early spring (particularly in specimens less than 12 mm long) but the production of gametes appears to be

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

FEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.
