Scale-Up of Human Amniotic Epithelial Cells Through Regulation of Epithelial-Mesenchymal Plasticity Under Defined Conditions.

Human amniotic epithelial cells (hAECs) have shown excellent efficacy in clinical research and have prospective applications in the treatment of many diseases. However, the properties of the hAECs and their proliferative mechanisms remain unclear. Here, single-cell RNA sequencing (scRNA-seq) is performed on hAECs obtained from amniotic tissues at different gestational ages and passages during in vitro culture.

Selective Degradation of TEADs by a PROTAC Molecule Exhibited Robust Anticancer Efficacy In Vitro and In Vivo.

Genetic mutations in components of the Hippo pathway frequently lead to the aberrant activation of TEADs, which is often associated with cancer. Consequently, TEADs have been actively pursued as therapeutic targets for diseases driven by TEAD overactivation. In this study, we report two series of TEAD PROTACs based on CRBN binders and VHL binders.

Nanoscopic Supercapacitance Elucidations of the Graphene-Ionic Interface with Suspended/Supported Graphene in Different Ionic Solutions.

Graphene-based supercapacitors have gained significant attention due to their exceptional energy storage capabilities. Despite numerous research efforts trying to improve the performance, the challenge of experimentally elucidating the nanoscale-interface molecular characteristics still needs to be tackled for device optimizations in commercial applications. To address this, we have conducted a series of experiments using substrate-free graphene field-effect transistors (SF-GFETs) and oxide-supported graphene field-effect transistors (OS-GFETs) to elucidate the graphene-electrolyte interfacial arrangement and corresponding capacitance under different surface potential states and ionic concentration environments.

Lanthanide-Assisted Function Tailoring of the HOF-Based Logic Gate Sensor Array for Biothiol Detection and Disease Discrimination.

The advancement of lanthanide fingerprint sensors characterized by targeted emission responses and low self-fluorescence interference for the detection of biothiols is of considerable importance for the early diagnosis and treatment of cancer. Herein, the lanthanide "personality function tailoring" HOF composite sensor array is designed for the specific discrimination of biothiols (GSH, Cys, and Hcy) based on the activation of various luminescent molecules, such as r-AuNCs/luminol via HOF surface proximity. Lumi-HOF@Ce serves as a versatile platform for catalyzing the oxidation of -phenylenediamine (OPD) to generate yellow fluorescent oligomers, accompanied by the fluorescence attenuation of luminol.

Protein tyrosine phosphatase PTPH1 potentiates receptor tyrosine kinase HER2 oncogenesis via a PDZ-coupled and phosphorylation-driven scaffold.

Cancer cell overexpresses numerus proteins, however, how these up-regulated proteins, especially those enzymatically opposite kinases and phosphatases, act together to promote oncogenesis is unknown. Here, we reported that protein tyrosine phosphatase H1 (PTPH1) is a scaffold protein for receptor tyrosine kinase (HER2) to potentiate breast tumorigenesis. PTPH1 utilizes its PDZ domain to bind HER2, p38γ, PBK, and YAP1 and to increase HER2 nuclear translocation, stemness, and oncogenesis.
