Long-Term Resistance of Drosophila melanogaster to the Mushroom Toxin Alpha-Amanitin. [PDF]
PLoS ONE, 2015 Insect resistance to toxins exerts not only a great impact on our economy, but also on the ecology of many species. Resistance to one toxin is often associated with cross-resistance to other, sometimes unrelated, chemicals. In this study, we investigated

The Landscape and Regulation of Histone Crotonylation in Mammalian Gametes and Early Embryos. [PDF]
Adv Sci (Weinh)Histone crotonylation undergoes a genome‐wide transition from broad domains to canonical narrow peaks during minor zygotic genome activation (ZGA). This remodeling is required for proper major ZGA and blastocyst formation. Disruption of this transition by transcriptional inhibition, metabolic perturbation, or HDAC1 dysfunction impairs embryonic ...

Calculating RNA degradation rates using large-scale normalization in mouse embryonic stem cells
STAR Protocols, 2023 Summary: Data normalization is critical to the process of estimating RNA degradation by analyzing RNA levels when transcription is blocked. Here, we present a protocol for measuring mRNA degradation rates, optimized for mouse embryonic stem cells, using ...

Mycotoxins in Basidiomycete Mycelium and Fruiting Bodies: Implications for Eu Novel Food Assessment and Selected International Regulatory Frameworks. [PDF]
Compr Rev Food Sci Food SafABSTRACT Advances in technology have enabled the efficient and sustainable production of basidiomycete vegetative mycelium, particularly from Pleurotus species, as a novel food source. However, mycelium has yet to receive regulatory approval in many global markets, requiring a better understanding of factors affecting its safety.
