AQP3 Influences Unexplained Recurrent Abortion by Regulating Trophoblast Cell Migration and Invasion via the METTL14/IGF2BP1/AQP3/PI3K/AKT Pathway.

Reduced trophoblast migration and invasion contribute to unexplained recurrent spontaneous abortion (URSA). Aquaporin 3 (AQP3) plays a crucial role in facilitating trophoblast migration and invasion during early pregnancy through fetal-maternal crosstalk. This study aimed to comprehensively investigate the mechanism involving AQP3 and its modulatory effects on human extravillous trophoblast (HTR-8/SVneo cells) migration and invasion.

The heterotrimeric RNA-dependent RNA polymerase (RdRp) of influenza A virus catalyzes viral RNA transcription (vRNA→mRNA) and replication (vRNA→cRNA→vRNA) by adopting different conformations. A switch from transcription to replication occurs at a relatively late stage of infection. We recently reported that the viral NS2 protein, expressed at later stages from a spliced transcript of the NS segment messenger RNA (mRNA), inhibits transcription, promotes replication and plays a key role in the transcription-to-replication switch.

The mammalian mitochondrial protein synthesis system produces 13 essential subunits of oxidative phosphorylation (OXPHOS) complexes. Translation initiation in mammalian mitochondria is characterized by the use of leaderless messenger RNAs (mRNAs) and non-AUG start codons, where the proofreading function of IF-3mt still remains elusive. Here, we developed a reconstituted mammalian mitochondrial translation system using in vitro transcribed and native mitochondrial transfer RNAs (tRNAs) to investigate IF-3mt's proofreading function.

Objective: Considering that the αvβ3 integrin plays an important role in tumor metastasis, this study investigated the involvement of these pathways in mediating the triiodothyronine (T3) effects on amphiregulin () expression.
Materials And Methods: We treated MCF-7 cells with T3 (10 nM) for 1 hour in the presence or absence of inhibitors for αvβ3 integrin (RGD peptide), MAPK (PD98059), PI3K (LY294002), and protein synthesis (cycloheximide [CHX]). A control group (C) received no T3 or inhibitors.
Esketamine alleviates depressive-like behavior in neuropathic pain mice through the METTL3-GluA1 pathway.

Esketamine, a newly developed antidepressant, is the subject of this research which seeks to explore its impact on depressive symptoms in neuropathic pain mice and the potential molecular mechanisms involved. Through transcriptome sequencing and bioinformatics analysis combined with in vivo studies, it was identified that esketamine markedly boosts the levels of the m6A methyltransferase METTL3 and the AMPA receptor GluA1 subunit. Esketamine activates METTL3, allowing it to bind with GluA1 mRNA, promoting m6A modification, thereby enhancing GluA1 expression at synapses.
