Abstract
FYCO1, an autophagy adaptor, plays an essential role in the trafficking toward the plus-end of microtubules and the fusion of autophagosomes. Autophagic dysfunction is involved in numerous disease states, including cancers. Previous studies have implicated FYCO1 as one of the critical genes involved in the adenoma to carcinoma transition, but the biological function and mechanism of FYCO1 in carcinogenesis remain unclear. This study aims to elucidate the role and mechanism of up- and downregulation of FYCO1 in mediating tumor effects in HeLa cells. Functionally, FYCO1 promotes cellular migration, invasion, epithelial-mesenchymal transition, invadopodia formation, and matrix degradation, which are detected through wound healing, transwell, immunofluorescence, and Western blot approaches. Interestingly, the data show that although FYCO1 does not affect HeLa cell proliferation, cell cycle distribution, nor vessels' formation, FYCO1 can block the apoptotic function. FYCO1 inhibits cleavage of PARP, caspase3, and caspase9 and increases Bcl-2/Bax ratio. Then, we used CK666, an Arp2/3 specific inhibitor, to confirm that FYCO1 may promote the migration and invasion of HeLa cells through the CDC42/N-WASP/Arp2/3 signaling pathway. Taken together, these results provide a new insight that FYCO1, an autophagy adaptor, may also be a new regulator of tumor metastasis.

Abstract
Background Tumor cells are known to release large numbers of exosomes containing active substances that participate in cancer progression. Abnormally expressed long noncoding RNAs (lncRNAs) have been confirmed to regulate multiple processes associated with tumor progression. However, the mechanism by which lncRNAs affect exosome secretion remains unclear. Methods The underlying mechanisms of long noncoding RNA LINC00511 (LINC00511) regulation of multivesicular body (MVB) trafficking, exosome secretion, invadopodia formation, and tumor invasion were determined through gene set enrichment analysis (GSEA), immunoblotting, nanoparticle tracking analysis, confocal colocalization analysis, electron microscopy, and invasion experiments. Results We revealed that the tumorigenesis process is associated with a significant increase in vesicle secretion in hepatocellular carcinoma (HCC). Additionally, LINC00511 was significantly more highly expressed in HCC tissues and is related to vesicle trafficking and MVB distribution. We also found that in addition to the formation of invadopodia in HCC progression, abnormal LINC00511 induces invadopodia formation in HCC cells by regulating the colocalization of vesicle associated membrane protein 7 (VAMP7) and synaptosome associated protein 23 (SNAP23) to induce the invadopodia formation, which are key secretion sites for MVBs and control exosome secretion. Finally, we revealed that LINC0051-induced invadopodia and exosome secretion were involved in tumor progression. Conclusions Our experiments revealed novel findings on the relationship between LINC00511 dysregulation in HCC and invadopodia production and exosome secretion. This is a novel mechanism by which LINC00511 regulates invadopodia biogenesis and exosome secretion to further promote cancer progression.
