Study summary Full title Epstein-Barr virus-encoded latent membrane protein 1 promotes extracellular vesicle secretion through syndecan-2 and synaptotagmin-like-4 in nasopharyngeal carcinoma cells All authors Chaoliang Liao, Qin Zhou, Zhibao Zhang, Xia Wu, Zhuan Zhou, Bo Li, Jinwu Peng, Liangfang Shen, Dan Li, Xiangjian Luo, Lifang Yang Journal J Pharm Sci Abstract Increasing evidence indicates that extracellular vesicles (EVs) play an important role in cancer cel (show more...)Increasing evidence indicates that extracellular vesicles (EVs) play an important role in cancer cell-to-cell communication. The Epstein-Barr virus (EBV)-encoded latent membrane protein 1 (LMP1), which is closely associated with nasopharyngeal carcinoma (NPC) pathogenesis, can trigger multiple cell signaling pathways that affect cell progression. Several reports have shown that LMP1 promotes EV secretion, and LMP1 trafficking by EVs can enhances cancer progression and metastasis. However, the molecular mechanism by which LMP1 promotes EV secretion is not well understood. In the present study, we found that LMP1 promotes EV secretion by upregulated syndecan-2 (SDC2) and synaptotagmin-like-4 (SYTL4) through nuclear factor (NF)-κB signaling in NPC cells. Further study indicated that SDC2 interacted with syntenin, which promoted the formation of the EVs, and SYTL4 is associated with the release of EVs. Moreover, we found that stimulation of EV secretion by LMP1 can enhance the proliferation and invasion ability of recipient NPC cells and tumor growth in vivo. In summary, we found a new mechanism by which LMP1 upregulates SDC2 and SYTL4 through NF-κB signaling to promote EV secretion, and further enhance cancer progression of NPC.

For the quantitative method, the reporting of measured EV concentration is expected. electron microscopy images Particle analysis: inclusion of a widefield and close-up electron microscopy image density gradient Separation method: density gradient, at least as validation of results attributed to EVs EV density Separation method: reporting of obtained EV density ultracentrifugation specifics Separation method: reporting of g-forces, duration and rotor type of ultracentrifugation steps antibody specifics Protein analysis: antibody clone/reference number and dilution lysate preparation Protein analysis: lysis buffer composition Study data Sample type Cell culture supernatant Sample origin transfected siSDC2 Focus vesicles extracellular vesicle Separation protocol Separation protocol Gives a short, non-chronological overview of the different steps of the separation protocol. dUC = (Differential) (ultra)centrifugation DG = density gradient UF = ultrafiltration SEC = size-exclusion chromatography IAF = immuno-affinity capture ExoQuick Protein markers EV: non-EV: Proteomics no Show all info Study aim Function/Biogenesis/cargo sorting/Mechanism of uptake/transfer Sample Species Homo sapiens Sample Type Cell culture supernatant EV-producing cells C666-1 EV-harvesting Medium Serum-containing, but physical separation of serum EVs and secreted EVs (e.g. Bioreactor flask) Separation Method Commercial kit ExoQuick Other Name other separation method ExoQuick Protein Concentration Method BCA Characterization: Lipid analysis No
