Abstract Background Metastasis is the key cause of death in ovarian cancer patients. To figure out the biological nature of cancer metastasis is essential for developing effective targeted therapy. Here we investigate how long non-coding RNA (lncRNA) SPOCD1-AS from ovarian cancer extracellular vesicles (EVs) remodel mesothelial cells through a mesothelial-to-mesenchymal transition (MMT) manner and facilitate peritoneal metastasis. Methods EVs purified from ovarian cancer cells and ascites of patients were applied to mesothelial cells. The MMT process of mesothelial cells was assessed by morphology observation, western blot analysis, migration assay and adhesion assay. Altered lncRNAs of EV-treated mesothelial cells were screened by RNA sequencing and identified by qRT-PCR. SPOCD1-AS was overexpressed or silenced by overexpression lentivirus or shRNA, respectively. RNA pull-down and RNA immunoprecipitation assays were conducted to reveal the mechanism by which SPOCD1-AS remodeled mesothelial cells. Interfering peptides were synthesized and applied. Ovarian cancer orthotopic implantation mouse model was established in vivo. Results We found that ovarian cancer-secreted EVs could be taken into recipient mesothelial cells, induce the MMT phenotype and enhance cancer cell adhesion to mesothelial cells. Furthermore, SPOCD1-AS embedded in ovarian cancer-secreted EVs was transmitted to mesothelial cells to induce the MMT process and facilitate peritoneal colonization in vitro and in vivo. SPOCD1-AS induced the MMT process of mesothelial cells via interacting with G3BP1 protein. Additionally, G3BP1 interfering peptide based on the F380/F382 residues was able to block SPOCD1-AS/G3BP1 interaction, inhibit the MMT phenotype of mesothelial cells, and diminish peritoneal metastasis in vivo. Conclusions Our findings elucidate the mechanism associated with EVs and their cargos in ovarian cancer peritoneal metastasis and may provide a potential approach for metastatic ovarian cancer therapeutics.

Abstract Background: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is effective for treating peritoneal metastasis. However, it is currently used in the limited areas. Thus, we performed a survey to evaluate the clinical desire for PIPAC in South Korea, one of the many countries where PIPAC has not yet been introduced.Methods: We performed an online survey between November and December 2019. The questionnaire consisted of 20 questions, which were divided into comprehensive, procedure, and cost inquiries including five, 13 and two questions, respectively. Results: A total of 164 respondents who answered the questionnaire. Among respondents, 41.7-50% majoring in ovarian cancer, pseudomyxoma peritonei, and malignant mesothelioma preferred PIPAC for the curative treatment of primary diseases, whereas 32.7-33.3% majoring in colorectal and hepatobiliary cancers chose it for the palliative treatment of recurrent diseases. Moreover, 66.7-95.2% considered PIPAC appropriate for the cancers the specialized in, and 76-78.7% expected a treatment response of more than 50% and considered grade 1 or 2 minor surgical complications acceptable. Finally, most of the respondents answered the reasonable costs to purchase and implement PIPAC once at between 1,000,000-5,000,000 KRW. Conclusions: This surgery may reflect on the availability, scope, and reasonable cost of PIPAC treatment in South Korea for introducing PIPAC.
