In addition, WIN 55,212-2 decreases cell surface expression of CD44, CD54, MHC class I and PD-L1 on oral and pancreatic tumor cells with the exception of PD-L1 expression on well-differentiated PL-12 pancreatic tumor cells which exhibits an increase in the expression rather than a decrease. Overall, we demonstrate that WIN 55,212-2 has an increased targeting activity against cancer stem cells/poorly differentiated oral and pancreatic tumor cells when compared to well-differentiated tumor cells, and furthermore, such differences in function do not correlate with the levels of CB1 and CB2 receptor expression on tumor cells, suggesting it's function either through post-receptor mediated activation and/or yet-to-be identified novel receptors. Intraperitoneal (IP) delivery of WIN 55-212-2 in humanized BLT mice is found to impart an activating potential for NK cells demonstrating increased NK cell mediated cytotoxicity and secretion of IFN-γ in our preliminary experiments. These results not only suggest a direct targeting of CSCs/poorly differentiated tumors by WIN 55-212-2 but also by indirect targeting of such tumors through the activation and increased functions of NK cells.</p></div>","PeriodicalId":72083,"journal":{"name":"Advances in cancer biology - metastasis","volume":"5 ","pages":"Article 100043"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S266739402200017X/pdfft?md5=10e396cf5272a210b1edee74f91026cd&pid=1-s2.0-S266739402200017X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45243472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exosomal miRNAs are miRNAs found inside the exosomal structure of 30–150 nm of an extracellular vesicle. The synthesis and biogenesis of these exosomal miRNA involve an endosomal sorting complex required for transport which releases miRNAs and relevant proteins to cause tumor heterogeneity, drug resistance, and cancer metastasis. Herein, we have highlighted the role of exosomal miRNAs in both drug resistance and cancer metastasis.

The development of cancer is associated with chronic inflammation, although inflammation is an essential biological process. The epithelial-mesenchymal transition (EMT) is a crucial step in development process of human tissue and involve in the regulatory pathways. On the contrary, the uncontrolled EMT is responsible for the initiation of cancer, its metastasis, immunosuppression, and resistance to antitumor treatment. Interestingly, there is an interrelationship between inflammation and EMT process. Usually, proinflammatory cytokines activate EMT inducing transcription factors (EMT-TFs), causing epithelial cells to change into cancerous mesenchymal cell by activating the mesenchymal cells markers, such as N- Cadherin, Fibronectin, Vimentin etc., and inhibiting the epithelial cells markers such as E− Cadherin, Claudin 1, Occludin, and β-catenin. Consequently, epithelial cells are dissociated, invasive, motile, resistant to therapy, resistant to apoptosis, and undergo mesenchymal cells angiogenesis. Some natural products and short RNAs have been identified to interfere with inflammation-EMT axis to inhibit cancer progression and metastasis.

Introducing miR-203b-3p into ovarian cancer cells suppressed cell migration, <em>in vitro</em> invasion and peritoneal metastatic colonization. With the aid of cytokine array and modified Cross-Linking, Ligation, and Sequencing of Hybrids (qCLASH), we identified C-X-C motif chemokine ligand 1 (CXCL1) mRNA as a target of miR-203b-3p. Recombinant CXCL1 largely restored cell migration/invasion and CXCL1 neutralizing antibody blocked cell migration/invasion. Intriguingly, miR-203b-3p targets CXCL1 in an unconventional manner: 1) miR-203b-3p targets the 5′-untranslated region (UTR) and protein coding region of CXCL1 mRNA and 2) seed sequences in miR-203b-3p are not the conventional nucleotides 2 to 8 observed for most of miRNA/target complementation. Finally, we show that epithelial cell adhesion molecule (EpCAM) aptamer can effectively deliver miR-203b-3p into ovarian cancer cells and EpCAM aptamer-delivered miR-203b-3p impeded peritoneal metastatic colonization and prolonged lifespan of tumor-bearing mice. In summary, our findings provide a novel mechanism in which attenuated miR-203b-3p expression sustains CXCL1 abundance and hence ovarian cancer progression.
