CircHIF1A overexpression and knockdown efficiencies in TNBC were validated by qRT-PCR (Supplementary Fig. 2A). The expression levels of linear HIF1A … See more Fused in sarcoma (FUS) belongs to the FET family of ubiquitously expressed RNA-binding proteins involved in multiple stages of RNA processing [30, 31]. Recently, FUS was … See more Interestingly, we found that ectopic expression of NFIB could increase circHIF1A expression, while NFIB knockdown led to … See more Because the potential roles of FUS in TNBC progression are largely unknown, we conducted functional experiments with FUS overexpression … See more

WebMar 10, 2024 · Epithelial-to-mesenchymal transition (EMT) is a dynamic program of cell plasticity aberrantly reactivated in cancer. The crosstalk between tumor cells and the tumoral microenvironment (TME) has a pivotal importance for the induction of the EMT and the progression toward a malignant phenotype. Notably, exosomes are key mediators of this … WebJul 15, 2024 · The RNA-binding protein FUS regulates the biogenesis of circHIF1A by interacting with flanking introns, and significantly promotes TNBC growth and metastasis . 4. Cis-Regulatory Elements. In addition to trans-acting factors that regulate circRNA biogenesis, many cis-regulatory elements can also influence the cyclization of RNA. In … WebJan 4, 2024 · Zhan et al. have found that circHIF1A from CAF-derived exosomes can be taken up by breast cancer cells and thus plays an important role in the regulation of cancer stem cell properties by sponging miR-580-5p and therefore changing CD44 expression. In addition, exosomal circsl7a6 secreted by CAFs is reported to promote the initiation of CRC. crystals and how they form
