Shorter juvenile telomere length is associated with higher survival to spawning in migratory Atlantic salmon [PDF]

, 2017
The risk of mortality associated with a long-distance migration will depend on an animal's physiological state, as well as the prevailing ecological conditions.

Effects of high water level on the river residence period of juvenile Chinese sturgeon Acipenser sinensis in the Yangtze River

Knowledge and Management of Aquatic Ecosystems, 2012
The migration time of newly hatched Acipenser sinensis from the spawning area (river km 1675) to the Yangtze estuary (rkm 0) was ascertained in the years 1996–2007 (time range 192–243 days), and its relationship to water levels surveyed at 12 typical ...

Oncogenic microRNA-4534 regulates PTEN pathway in prostate cancer. [PDF]

, 2016
Prostate carcinogenesis involves alterations in several signaling pathways, the most prominent being the PI3K/AKT pathway. This pathway is constitutively active and drives prostate cancer (PCa) progression to advanced metastatic disease. PTEN, a critical

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Étude du comportement de smolts de saumon atlantique (Salmo salar L.) au niveau de la prise d'eau de l'usine hydroélectrique de Pointis sur la Garonne et estimation de la dévalaison au niveau du barrage de Rodère

Knowledge and Management of Aquatic Ecosystems, 1999
Une expérimentation a été menée en 1998 au niveau de la prise d'eau de l'usine hydroélectrique de Pointis, sur la Garonne, de manière à déterminer, grâce à la technique de radio-pistage, le meilleur emplacement d'un futur dispositif de dévalaison.

Transcription factor KLF15 inhibits the proliferation and migration of gastric cancer cells via regulating the TFAP2A-AS1/NISCH axis

Biology Direct, 2021
Background Recently, overwhelming evidence supports that long noncoding RNAs (lncRNAs) play crucial roles in the occurrence and progression of tumors. However, the role and mechanism of lncRNA TFAP2A-AS1 in human gastric cancer (GC) remains unclear. Thus,

First wide-angle view of channelized turbidity currents links migrating cyclic steps to flow characteristics [PDF]

, 2016
Field observations of turbidity currents remain scarce, and thus there is continued debate about their internal structure and how they modify underlying bedforms.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Spatio-temporal regulation of concurrent developmental processes by generic signaling downstream of chemokine receptors [PDF]

, 2018
Chemokines are secreted proteins that regulate a range of processes in eukaryotic organisms. Interestingly, different chemokine receptors control distinct biological processes, and the same receptor can direct different cellular responses, but the basis ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
