Bridging maternal effects and epitranscriptomics: A novel perspective in developmental biology
Developmental Dynamics, EarlyView.Abstract Maternal effects, encompassing both genetic (maternally expressed gene products) and non‐genetic (maternal state) influences, are powerful determinants of offspring phenotype, yet their RNA‐level mechanisms remain incompletely resolved. In parallel, epitranscriptomics, an emerging field centered on chemical modifications to RNA, has revealed ...

Cell cycle length, cell size, and proliferation rate in hydra stem cells [PDF]
, 1990 We have analyzed the cell cycle parameters of interstitial cells in Hydra oligactis. Three subpopulations of cells with short, medium, and long cell cycles were identified. Short-cycle cells are stem cells; medium-cycle cells are precursors to nematocyte

Environmental and Molecular Mutagenesis, EarlyView.Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

Small, EarlyView.Little is known about the effects of polystyrene nanoplastics (PS‐NPs) on gonadotropin releasing hormone (GnRH) neurons, which control puberty onset and fertility. By applying tailored in vitro GnRH neuron models, this article shows how PS‐NPs are internalized and impact hormone secretion and cell migration, through gene expression changes. Ultimately,
