Enhancement of the yield of poly (ethylene terephthalate) hydrolase production using cell membrane protection strategy.

Biodegradation, particularly via enzymatic degradation, has emerged as an efficient and eco-friendly solution for Poly (ethylene terephthalate) (PET) pollution. The production of PET hydrolases plays a role in the large-scale enzymatic degradation. However, an effective variant, 4Mz, derived from Thermobifida fusca cutinase (Tfu_0883), was previously associated with a significant reduction in yield when compared to the wild-type enzyme.

Enantioselective Alkylation of Primary C()-H Bonds in -Methyl Tertiary Amine Enabled by Iridium Complex of Axially Chiral β-Aryl Porphyrins.

A fine-tuning of enantioselective carbene insertion into primary C()-H bonds has been realized in challenging substrates, such as -methyl unblocked aromatic and non-deactivated aliphatic tertiary amines, in which sterically demanding β-axially chiral iridium porphyrin catalysts play a crucial role. This primary C()-H alkylation with diazo compounds affords a series of β-chiral tertiary amines in high yields with excellent enantioselectivities. Notably, the protocol was successfully applied to the postmodification of chiral bicuculline, yielding the desired derivative with high diastereoselectivity.

: delineation of fungal genera based on phylogenomic analyses, genomic relatedness indices and genomics-based synapomorphies.

A correct classification of fungi, including yeasts, is of prime importance to understand fungal biodiversity and to communicate about this diversity. Fungal genera are mainly defined based on phenotypic characteristics and the results of single or multigene-based phylogenetic analyses. However, because yeasts often have less phenotypic characters, their classification experienced a strong move towards DNA-based data, from short ribosomal sequences to multigene phylogenies and more recently to phylogenomics.

FTO promotes gefitinib-resistance by enhancing PELI3 expression and autophagy in non-small cell lung cancer.

The established recognition of N6-methyladenosine (m6A) modification as an indispensable regulatory agent in human cancer is widely accepted. However, the understanding of m6A's role and the mechanisms underlying its contribution to gefitinib resistance is notably limited. Herein, using RT-qPCR, Western blot, Cell proliferation and apoptosis, as well as RNA m6A modification assays, we substantiated that heightened FTO (Fat Mass and Obesity-associated protein) expression substantially underpins the emergence of gefitinib resistance in NSCLC cells.
