Extracellular vesicles (EVs) are one of several tools that cells use to communicate with each other. This communication is facilitated by a number of surface-associated proteins and the cargo of the vesicles. For several cancer types, the amount of EVs is observed to be up-regulated in patients compared to healthy individuals, possibly signifying the presence of an aberrant process. The hypoxia-induced release of EVs from cancer cells has been hypothesized to cause the malignant transformation of healthy recipient cells. In this study, the phenotype of cells and EVs from the ovarian cancer cell lines, COV504, SKOV3, and Pt4, were quantified and analysed under normoxic and hypoxic conditions. It was shown that both cells and EVs express common markers and that the EV phenotype varies more than the cellular phenotype. Additionally, cells subjected to 24 hours of hypoxia compared to normoxia produced more EVs. The phenotyping of EVs from cancer cell lines provides information about their molecular composition. This information may be translated to knowledge regarding the functionality of EVs and lead to a better understanding of their role in cancer.

Background: Prostate cancer (PC) is the most frequently diagnosed cancer in men and continues to be a major cause of cancer-related mortality worldwide. In recent years, non-coding RNAs (ncRNAs) have emerged as a significant focus in molecular biology research, playing a pivotal role in the development and progression of PC. This study employed bibliometric analysis to explore the global outputs, research hotspots, and future trends in ncRNA-related PC research over the past 20 years.

Skeletal muscle (SKM) has crucial roles in locomotor activity and posture within the body and also functions have been recognized as an actively secretory organ. Numerous bioactive molecules are secreted by SKM and transported by extracellular vesicles (EVs), a novel class of mediators of communication between cells and organs that contain various types of cargo molecules including lipids, proteins and nucleic acids. SKM-derived EVs (SKM-EVs) are intercellular communicators with significant roles in the crosstalk between SKM and other organs.

Electric vehicles (EVs) are crucial for addressing the intertwined challenges of climate change and air pollution. The multiaspect benefits of EVs are highly dependent on local climate conditions, yet the impacts of regional heterogeneity in the context of future climate change remain unclear. Here, we develop a systemic modeling framework integrating fleet modeling, emission projection, index decomposition analysis, and detailed cost assessment to identify local drivers and potential trade-offs behind electrification.

Extracellular vesicles (EVs) are heterogeneously sized, cell-derived nanoparticles operating as proficient mediators of intercellular communication. They are produced by normal as well as diseased cells and carry a variety of cargo. While the molecular details of EV biology have been worked out over the past two decades, one question that continues to intrigue many is how are EVs able to evade the phagocytic immune cells while also being effectively internalized by the target cell or tissue.

Extracellular vesicles (EVs) are promising therapeutic carriers for their ideal nano-size and intrinsic biocompatibility, while rapid clearance and limited targeting ability are the major setbacks of EVs. With minimal absorption into the systemic circulation, inhalation for pulmonary disease therapy minimizes off-target toxicity to other organs and offers a safe and effective treatment for respiratory disorders. Herein, a nano-grid carrier made of boronated cyclodextrin framework (BCF) was prepared for pH/HO responsive release of EVs.
