Trazodone, dibenzoylmethane and tauroursodeoxycholic acid do not prevent motor dysfunction and neurodegeneration in Marinesco-Sjögren syndrome mice.

Lavigna G, Grasso A, Pasini C et al. · 2025 · PloS one

There is no cure for Marinesco-Sjögren syndrome (MSS), a genetic multisystem disease linked to loss-of-function mutations in the SIL1 gene, encoding a BiP co-chaperone. Previously, we showed that the PERK kinase inhibitor GSK2606414 delays…

CD320 expression is increased in breast cancer stem cells but does not promote their expansion or alter key histone methylation marks.

Carney C, Jenkins L, Jewell C et al. · 2025 · microPublication biology

Several lines of evidence suggest a potential link between stemness and vitamin B12, which contributes to S-adenosylmethionine (SAM) generation and hence methylation-dependent epigenetic control. Here we found that the vitamin B12…
