Amitraz Resistance in French Mite Populations-More Complex Than a Single-Nucleotide Polymorphism.

Resistance against amitraz in mite populations has become a subject of interest in recent years due to the increasing reports of the reduced field efficacy of amitraz treatments, especially from some beekeepers in France and the United States. The loss of amitraz as a reliable tool to effectively reduce mite infestation in the field could severely worsen the position of beekeepers in the fight to keep infestation rates in their colonies at low levels. In this publication, we present data from French apiaries, collected in the years 2020 and 2021.

as a novel next generation probiotic against influenza.

The gut-lung axis is critical during viral respiratory infections such as influenza. Gut dysbiosis during infection translates into a massive drop of microbially produced short-chain fatty acids (SCFAs). Among them, butyrate is important during influenza suggesting that microbiome-based therapeutics targeting butyrate might hold promises.

HnRNP A1 tethers KSRP to an exon splicing silencer that inhibits an erythroid-specific splicing event in PU.1-induced erythroleukemia.

Exon 16 inclusion is a critical splicing event that triggers the production of a functional protein 4.1R in mature normal erythroblasts, and is obviated in PU.1-induced erythroleukemia cells.

Downregulation of the Spi-1/PU.1 oncogene induces the expression of TRIM10/HERF1, a key factor required for terminal erythroid cell differentiation and survival.

Sustained expression of the Spi-1/PU.1 and Fli-1 oncoproteins blocks globin gene activation in mouse erythroleukemia cells; however, only Spi-1/PU.1 expression inhibits the inclusion of exon 16 in the mature 4.
