How to estimate age of old bottlenose dolphins (Tursiops truncatus); by tooth or pectoral flipper?

Frontiers in Marine Science, 2023
Multiple techniques have been used for estimating age in bottlenose dolphins (Tursiops truncatus). The longest established technique is via counts of growth later groups (GLGs) in the longitudinal section of an extracted mandibular tooth.

Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

Advanced Science, EarlyView.
Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Capturing foraging and resting behavior using nested multivariate Markov models in an air-breathing marine vertebrate

Movement Ecology, 2018
Background Matching animal movement with the behaviors that shape life history requires a rigorous connection between the observed patterns of space use and inferred behavioral states. As animal-borne dataloggers capture a greater diversity and frequency

Metallothioneins in marine mammals.

Cellular and molecular biology (Noisy-le-Grand, France), 2000
Metallothioneins (MTs) have been detected in livers and kidneys of 10 marine mammals species (Pinnipeds and Odontocetes). Characterization of renal MTs of striped dolphin has shown that the protein has two isoforms (MT-1 and MT-2) with a molecular weight estimated around 6,800.

RNA Promotes Synapsin Condensates That Organize Synaptic Vesicles in Live Neurons and Enable Localized Translation in Reconstituted System

Advanced Science, EarlyView.
Condensates at synapses organize synaptic vesicles (SVs) and are crucial for efficient neurotransmitter release, yet how RNA contributes to this mesoscale architecture remains poorly understood. Here we uncover that RNA modulates synapsin–driven condensates.

Synthesis and Activity‐Based Protein Profiling Identifies Aldo‐Keto Reductase 1C3 as Target Protein of Myxoglucamides

Angewandte Chemie International Edition, EarlyView.
Myxoglucamide A—a novel glycolipopeptide isolated from myxobacteria—was synthesized, and activity‐based protein profiling identified aldo‐keto reductase 1C3 (AKR1C3) as its main target in human cells. Structure‐activity relationship studies, together with biophysical characterization and X‐ray crystallography, elucidated the structural basis of AKR1C3 ...
