Polymerization of proanthocyanidins under the catalysis of miR397a-regulated laccases in Salvia miltiorrhiza and Populus trichocarpa.

Proanthocyanidins (PAs) play significant roles in plants and are bioactive compounds with health benefits. The polymerization mechanism has been debated for decades. Here we show that laccases (LACs) are involved in PA polymerization and miR397a is a negative regulator of PA biosynthesis in Salvia miltiorrhiza and Populus trichocarpa.

MET amplification correlates with poor prognosis and immunotherapy response as a subtype of melanoma: a multicenter retrospective study.

Background: Mesenchymal epithelial transition factor (MET) variant is an independent prognostic factor for worse prognosis in patients with lung cancer or gastroesophageal adenocarcinoma. MET gene variants can be regarded as a subtype of melanoma but there is a lack of studies regarding the frequency of MET genetic alterations and the efficacy of immunotherapy in melanoma patients. The purpose of this study is to explore potential therapeutic strategies for melanoma subtypes with MET alterations.

The role of lysosomes as intermediates in betacoronavirus PHEV egress from nerve cells.

Betacoronaviruses, including severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and mouse hepatitis virus (MHV), exploit the lysosomal exocytosis pathway for egress. However, whether all betacoronaviruses members use the same pathway to exit cells remains unknown. Here, we demonstrated that porcine hemagglutinating encephalomyelitis virus (PHEV) egress occurs by Arl8b-dependent lysosomal exocytosis, a cellular egress mechanism shared by SARS-CoV-2 and MHV.
