    Abstract

    PEAK1 Y635 Phosphorylation Regulates Cell Migration through Association with Tensin3 and Integrins

    Researchers used BioID to interrogate the interactomes of β1 and β3 integrins in epithelial cells and identified PEAK1 as an interactor of the RGD-binding integrins α5β1, αVβ3, and αVβ5 in focal adhesions.

    Abstract

    Protein-Encapsulated Doxorubicin Reduces Cardiotoxicity in hiPSC-Cardiomyocytes and Cardiac Spheroids While Maintaining Anticancer Efficacy

    The authors used human induced pluripotent stem cell-derived (hiPSC) cardiomyocytes, endothelial cells, cardiac fibroblasts, multi-lineage cardiac spheroids, patient-specific hiPSCs, and multiple human cancer cell lines to compare the anticancer efficacy and reduced cardiotoxicity of single protein encapsulated doxorubicin, to standard unformulated doxorubicin.

    Abstract

    Human Aortic Smooth Muscle Cell Regulation by METTL3 via Upregulation of m6A NOTCH1 Modification and Inhibition of NOTCH1

    Human aortic smooth muscle cells (HASMCs) were cultured. METTL3 was knocked down and overexpressed. Then, both METTL3 and NOTCH1 were simultaneously knocked down in HASMCs.
