Abstract
Exosomes are a subpopulation of extracellular vesicles (EVs) secreted by cells. In cancer, they are key cellular messengers during cancer development and progression. Tumor-derived exosomes (TEXs) promote cancer progression. In oral cancer, the major complication is oral squamous cell carcinoma (OSCC). Exosomes show strong participation in several OSCC-related activities such as uncontrolled cell growth, immune suppression, angiogenesis, metastasis, and drug and therapeutic resistance. It is also a potential biomarker source for oral cancer. Some therapeutic exosome sources such as stem cells, plants (it is more effective compared to others), and engineered exosomes reduce oral cancer development. This therapeutic approach is effective because of its specificity, biocompatibility, and cell-free therapy (it reduced side effects in cancer treatment). This article highlights exosome-based theranostics signatures in oral cancer, clinical trials, challenges of exosome-based oral cancer research, and future improvements. In the future, exosomes may become an effective and affordable solution for oral cancer.

Abstract
PURPOSE The aim of this study was to perform radiotheranostics with radioiodinated monoclonal antibodies (mAbs) for targeting cancer stem cells (CSCs) in human colorectal cancer xenografts and evaluate the relative advantage of a cocktail containing both [131I]CD133 mAb and [131I]CD44 mAb. PROCEDURES Tumor-bearing mice were randomly divided into eight groups: [131I]CD133mAb, [131I]CD44 mAb, [131I]IgG isotype control, radioiodinated mAb cocktail, CD133 mAb, CD44 mAb, unradioiodinated mAb cocktail, and saline groups. In vivo single photon emission computed tomography (SPECT) imaging was used to monitor dynamically changes in the CSC population after treatment. The radioactivity uptake of tumors was quantified ex vivo. The expression of CD133 and CD44 after treatment was also assessed by immunohistochemistry and western blot. Tumor growth curves and survival curves were generated to assess treatment efficacy. Cell apoptosis and proliferation in xenografts 30 days after treatment were measured by TdT-mediated dUTP-biotin nick end labeling (aka, TUNEL) and Ki67 staining. The expression levels of biomarkers in xenografts 30 days after treatment were measured by flow cytometry. RESULTS The radioimmunoimaging (RII) with in vivo SPECT showed that the CSC-targeting radioimmunotherapy (RIT) groups ([131I]CD133 mAb, [131I]CD44 mAb, and radioiodinated mAb cocktail groups) had intense accumulations of radiolabeled agents in the tumor areas. The ex vivo biodistribution confirmed these findings. In the CSC-targeting RIT groups, immunohistochemistry and western blot indicated significant reduction of specific target expression in the xenografts. The tumor growth curves and survival curves showed that the CSC-targeting RIT significantly inhibited tumor growth and prolonged mean survival, respectively. Significantly increased apoptosis and decreased proliferation in xenografts further confirmed the therapeutic efficacy of CSC-targeting RIT. Flow cytometry showed that the decreases in CSCs correlated with the presence of the corresponding antibodies. CONCLUSIONS Our results suggest that the CSC-targeting RIT can effectively reduce CSCs which consequently inhibits tumor development. The radioiodinated mAb cocktail may generate enhanced CSC-targeting specificity.

Abstract
The processes of recurrence and metastasis, through which cancer relapses locally or spreads to distant sites in the body, accounts for more than 90% of cancer-related deaths. At present there are very few treatment options for patients at this stage of their disease. The main obstacle to successfully treat advanced cancer is the cells' ability to change in ways that make them resistant to treatment. Understanding the cellular mechanisms that mediate this cancer cell plasticity may lead to improved patient survival. Epigenetic reprogramming, together with tumor microenvironment, drives such dynamic mechanisms favoring tumor heterogeneity, and cancer cell plasticity. In addition, the development of new approaches that can report on cancer plasticity in their native environment have profound implications for studying cancer biology and monitoring tumor progression. We herein provide an overview of recent advancements in understanding the mechanisms regulating cell plasticity and current strategies for their monitoring and therapy management.

Abstract
Tumor-derived exosomes (TDEs) participate in formation and progression of different cancer processes, including tumor microenvironment (TME) remodeling, angiogenesis, invasion, metastasis and drug-resistance. Exosomes initiate or suppress various signaling pathways in the recipient cells via transmitting heterogeneous cargoes. In this review we discuss exosome biogenesis, exosome mediated metastasis and chemoresistance. Furthermore, tumor derived exosomes role in tumor microenvironment remodeling, and angiogenesis is reviewed. Also, exosome induction of epithelial mesenchymal transition (EMT) is highlighted. More importantly, we discuss extensively how exosomes regulate drug resistance in several cancers. Thus, understanding exosome biogenesis, their contents and the molecular mechanisms and signaling pathways that are responsible for metastasis and drug-resistance mediated by TDEs may help to devise novel therapeutic approaches for cancer progression particularly to overcome therapy-resistance and preventing metastasis as major factors of cancer mortality.
