Lipid dependence has been observed in various types of cancer, including high‑grade serous ovarian carcinomas (HGSOC), which is a lethal form of gynecological malignancy. ANGPTL3, PCSK9, and Apo CIII are pivotal lipid‑modulating factors, and therapeutic antibodies have been developed against each one (Evinacumab, Evolocumab andVolanesorsen, respectively). The roles ‑if any‑ of ANGPTL3, PCSK9, and Apo CIII in HGSOC are unclear. Moreover, levels of these lipid‑modulating factors have never been reported before in HGSOC. In this study, circulating levels of ANGPTL3, PCSK9, and Apo CIII, along with lipid profiles, are examined to verify whether one or many of these lipid‑regulating factors are associated with HGSOC.  \nMethods ELISA kits were used to measure ANGPTL3, PCSK9 and Apo CIII levels in plasma samples from 31 women with HGSOC and 40 women with benign ovarian lesions (BOL) before treatment and surgery. A Roche Modular ana‑ lytical platform measured lipid panels, Apo B and Lp(a) levels.  \nResults ANGPTL3 levels were higher in women with HGSOC (84 ng/mL, SD: 29 ng/mL, n = 31) than in women  \nwith BOL (67 ng/mL, SD: 31 ng/mL, n = 40; HGSOC vs. BOL P = 0 . 019) . Associations between the lipid panel and ANGPTL3, and the inverse relationship between HDL‑cholesterol and triglycerides, were present in women with BOL but not with HGSOC. PCSK9 and Apo CIII were not associated with HGSOC.  \nConclusions In this cohort of 71 women, ANGPTL3 levels were increased in HGSOC patients. The presence of HGSOC disrupted the classic inverse relationship between HDL and triglycerides, as well as the association between the lipid panel and ANGPTL3 . These associations were only maintained in cancer‑free women. Given the availability of Evi‑ nacumab, a therapeutic antibody against ANGPTL3, the current finding prompts an assessment of whether ANGPTL3 inhibition has therapeutic potential in HGSOC.  \nKeywords ANGPTL3, Evinacumab, PCSK9, Apo CIII, Lp(a), Lipid profile, High‑grade serous ovarian cancer  \n*Correspondence:  \nAnne Gangloff  \nanne.gangloff.1@ulaval.ca; anne.gangloff@crchudequebec.ulaval.ca Full list of author information is available at the end of the article  \n© Crown 2024.
