N6‐Methyladenosine (m6A) in Liver Disease: Pathogenic Mechanisms and Therapeutic Potential

iNew Medicine, EarlyView.
ABSTRACT Accumulating evidence highlights the critical role of epigenetic modifications, particularly N6‐methyladenosine (m6A), in liver disease. As the most abundant RNA modification in eukaryotic cells, m6A is dynamically regulated by multicomponent m6A methyltransferases (e.g., METTL3 and METTL14), demethylases (FTO and ALKBH5), and m6A‐binding ...

Immunomodulatory and Cytotoxic Properties of Enniatin B1 in Porcine Alveolar Macrophages

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study investigates the immunomodulatory effects of Enniatin B1 (ENNB1), an emerging mycotoxin, on porcine alveolar macrophages (PAMs), a species‐specific model relevant to human innate immunity. PAMs were exposed to increasing ENNB1 concentrations (0.5–6 μM) over 6, 24, and 48 h.

Nutrient composition and heavy metal accumulation in water hyacinth [Eichhornia crassipes (Mart.) Solms] and water lettuce (Pistia stratiotes L.) from the Dande River, Nepal: Implications for use as alternative feed resources

JSFA reports, EarlyView.
Abstract Background The proliferation of invasive aquatic macrophytes poses a significant ecological challenge globally, while many tropical regions face chronic shortages of affordable livestock feed. This study addresses this dual problem by assessing two invasive species, water hyacinth (Eichhornia crassipes) and water lettuce (Pistia stratiotes ...
