Inhibition of Ornithine Decarboxylase 1 Mitigates Denervation‐Induced Muscle Atrophy by Suppressing Proteolysis and Preserving Muscle Stem Cell Homeostasis

Cell Proliferation, Volume 59, Issue 10, October 2026.
Polyamine metabolism is innervation responsive and involved in denervation‐induced muscle atrophy. Inhibition of polyamine metabolism attenuates muscle atrophy by restraining proteolysis and preserving MuSCs homeostasis. Denervation‐induced activation of FAP‐derived FGF7 drives premature MuSCs activation, while DFMO suppresses this paracrine cue to ...

Photochemical effects of Mars‐like UV irradiation on carboxylic acids in carbonaceous chondrites and expectations for abiotic background organics on Mars

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2445-2465, October 2026.
Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

Genome architecture modulates 35S and 5S rDNA homogenization in Asteraceae

The Plant Journal, Volume 128, Issue 2, October 2026.
SUMMARY Concerted evolution is the model by which multicopy gene families are homogenized across genomes, with ribosomal DNA (rDNA) as its textbook example. However, the extent and efficiency of this process may vary depending on genomic factors. The plant family Asteraceae provides a natural comparative system to address the evolutionary dynamics of ...

Abundances in Damped Lyα Galaxies [PDF]

, 2006
Damped Lyα galaxies provide a sample of young galaxies where chemical abundances can be derived throughout the whole universe with an accuracy comparable to that for the local universe. Despite a large spread in redshift, HI column density and metallicity, DLA galaxies show a remarkable uniformity in the elemental ratios rather suggestive of similar ...
