Abstract

Extracellular vesicles (EVs) are membrane structures that enclose proteins, lipids, RNAs, metabolites, growth factors, and cytokines. EVs derived from mesenchymal stem cells (MSCs) can either stimulate or inhibit tumor growth in various malignancies through paracrine signaling. Tumor-associated MSCs (TA-MSCs), often described as "wounds that never heal," actively participate in the development, propagation, and metastasis of tumors, impacting the immunological state of the tumor microenvironment. For instance, TA-MSCs can alter immune cell recruitment and cytokine production, leading to a pro-tumorigenic environment. Consequently, both the tumor and its microenvironment undergo functional alterations, the cargo of exosomes is modified, and an abnormal tumor-associated MSC phenotype is acquired. MSC-EVs contain exosome microRNA with both tumor-inhibitory and tumor-supportive effects. For example, MSC-EVs have been shown to deliver tumor-suppressive microRNAs that inhibit cancer cell proliferation and induce apoptosis. This review outlines the criteria for the modification, isolation, and characterization of exosomes, as well as their application in cancer, providing insights for clinical use. By understanding these mechanisms, we can better harness MSC-EVs for therapeutic purposes.Keywords: mesenchymal stem cell, extracellular vesicle, exosome, cancer therapy, drug delivery

Abstract

BACKGROUND: Age contributes to body composition alteration, rises a common disorder in elderly known as sarcopenic obesity (SO), which is characterized by the combination of obesity (excess fat mass) and sarcopenia (reduced skeletal muscle mass) clinical form and function.CONTENT: The primary cause of SO is insulin resistance. Glucose transporter 4 (GLUT4) dysfunction results in impaired fatty acids oxidation. Decreased muscle mass results in lower mitochondria number and volume. Both will increase oxidative stress. Together with altered myokines in SO, oxidative stress was promoted and lead to higher M1 macrophages and failure in autophagy. The pro-inflammatory condition and dysbiosis links SO to a variety of cardiometabolic conditions, including non-alcoholic fatty liver disease, type 2 diabetes, and cardiovascular disease. The mortality, comorbidities, cardiometabolic diseases, and disability or impairment of SO is higher compare to obesity or sarcopenia alone. Some treatments have been developed for SO including adequate dietary intake, vitamin D and antioxidant supplementation, and exercises.SUMMARY: SO is more prevalent among the elderly and has a significant negative impact on their quality of life. Therefore, maintaining muscle mass and strength as well as preventing obesity should be the key goals of initiatives to support healthy aging.KEYWORDS: aging, body composition, obesity, sarcopenia, skeletal muscle, metabolic syndrome
