Marine Fish Egg Hydration Is Aquaporin-Mediated [PDF]

open access: yesScience, 2005
The positive buoyancy of marine fish eggs in sea water, allowed by hydration of the oocyte, is critical for their survival and dispersion in the ocean. We isolated an aquaporin, SaAQP1o, that belongs to a unique subfamily of aquaporin-1—like channels specifically evolved in teleosts and mainly expressed in the ovary.

Effects of collision shock on semi-buoyant fish egg hatchings in high-speed streams

open access: yesGlobal Ecology and Conservation
During downstream drifting in high-speed steams, semi-buoyant fish eggs can run onto rocks, boats, and other surfaces. This will result in the abrupt and severe collision shock to the fish eggs, causing damage to fish eggs and potentially leading to ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Interrogating the immune landscape of microsatellite stable RAS‐mutated colon cancer

open access: yesMolecular Oncology, EarlyView.
COLOSSUS project RAS‐mutated MSS colon cancer study explored transcriptomics and immune cell density by immunohistochemistry (IHC), Immunoscore (IS), ISIC/TuLIS scores, mutation counts, and detected different prevalences but similar microenvironment composition across immune markers with clinical relevance for future immunotherapy combination ...

The Eggs of the Sucker-fish [PDF]

open access: yesNature, 1926
IN a letter on the eggs of the pilot-fish in NATURE of August 14, 1926, p. 228, Mr. K. H. Barnard also mentions the eggs of the sucker-fish (Echeneis naucrates) “which are apparently still undescribed”. During my researches on the eggs and larvae of East Indian fishes (cf. Treubia, vol. 2, p. 97; vol. 3, p. 38; vol. 5, p. 408; vol. 6, p. 297; vol. 8, p.

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

open access: yesFEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...
