Summary The potential for using therapeutic antisense oligonucleotides (ASOs) has been hampered by lack of understanding how they enter cells and subsequently access their targets. Endocytosis contributes to ASO uptake, but the machinery mediating subsequent trafficking permit suppression target mRNAs not described. Here, we show that engagement with a scavenger receptor (CD44) activates ERK-RSK axis promote serine phosphorylation tyrosine kinase (EPHA2). Serine EPHA2 permits endocytosis, trafficking, accumulation ASOs in nuclear-adjacent endosomes. These endosomes then become leaky, allowing escape effectively suppress mRNA expression. Inhibition stress granule-mediated repair leaky further enhances effectiveness. data identify an endocytic route nucleus which may be exploited maximise effectiveness ASO-mediated therapies.

Abstract Research into cancer treatment has been mainly focused on developing therapies to directly target cells. Over the past decade, extensive studies have revealed critical roles of tumour microenvironment (TME) in initiation, progression, and drug resistance. Notably, cancer-associated fibroblasts (CAFs) emerged as one primary contributors shaping TME, creating a favourable environment for development. Many preclinical identified promising targets CAFs, demonstrating remarkable efficacy some CAF-targeted treatments models. Encouraged by these compelling findings, therapeutic strategies now advanced clinical evaluation. We aim provide comprehensive review relevant subjects including CAF-related markers targets, their multifaceted roles, current landscape ongoing trials.

Given the pivotal role of Eph-Ephrin signaling pathway in tumor progression, agonists or antagonists targeting Eph/Ephrin have emerged as promising anticancer strategies. However, implications glycosylation modifications within and their targeted protein therapeutics remain elusive. Here, we identify that N-glycosylation receptor-binding domain (RBD) ephrin B1 (EFNB1) is indispensable for its functional repertoire. Notably, compared to wild-type EFNB1, glycosylation-deficient N139D mutant drastically diminishes sensitivity cells chemotherapeutic agents, suggesting existence both glycosylation-dependent independent effects mediated by EFNB1. Transcriptomic analysis highlights immune response oxidative phosphorylation primary pathways modulated modifications. In coculture systems, EFNB1-RBD-Fc recombinant protein, while inhibiting B-lymphoma cells, also exerts differential impacts on stromal depending status. Furthermore, efficacy glycosylated non-glycosylated influenced endogenous EFNB1 levels cells. Taking together, this study demonstrates complexity multifaceted roles modulating function. These findings underscore need a nuanced understanding patterns Eph/Ephrin-targeted therapies optimize therapeutic potential.
