In ovarian cancer, adipose-derived stem cells from the omentum (O-ASCs) play a crucial role in supporting the tumor and its tumorigenic microenvironment, further propagating epigenetic abnormalities and dissemination of the disease. Epigallocatechin gallate (EGCG), a DNA methyltransferase inhibitor derived from green tea, and Indole-3-carbinol (I3C), a histone deacetylase inhibitor from cruciferous vegetables, carry promising effects in reprograming aberrant epigenetic modifications in cancer. Therefore, we demonstrate the action of these diet-derived compounds in suppressing the growth of 3D ovarian cancer spheroids or organoids as well as post-treatment cancer recovery through proliferation, migration, invasion, and colony formation assays when compared to the synthetic epigenetic compound Panobinostat with or without standard chemotherapy. Finally, given the regulatory role of the secretome in growth, metastasis, chemoresistance, and relapse of disease, we demonstrate that natural epigenetic compounds can regulate the secretion of protumorigenic growth factors, cytokines, extracellular matrix components, and immunoregulatory markers in human ovarian cancer specimens. While further studies are needed, our results suggest that these treatments could be considered in the future as adjuncts to standard chemotherapy, improving efficiency and patient outcomes.  \nKeywords: natural epigenetic compounds; ovarian cancer; secretome; tumor microenvironment; organoids; spheroids  \n1. Introduction  \nDespite countless advancements in care and treatment, ovarian cancer continues to bea challenging and deadly disease. In the United States alone, 19,880 new cases of ovarian cancer were estimated to be diagnosed in 2022 . Overall, ovarian cancer ranks fifth among causes of death in women, leading to more deaths than any other gynecologic cancer [1–3] . The current standard treatment comprises a combination of cytoreductive surgery, with or without platinum-based chemotherapy [3–5] . While initial management aims to provide a cure, diagnosis at advanced stages, alongside resistance and recurrence of disease, have posed challenges to the optimal management of ovarian cance","cbCaijFqoo2WzsSB","https://ap.wps.com/l/cbCaijFqoo2WzsSB","pdf",7785594,27,"English","# Abstract\n# Introduction\n## Rationale: ovarian cancer mortality and treatment limits\n## Epigenetics, chemoresistance, and tumor microenvironment\n## Synthetic epigenetic compounds and toxicity concerns","[{\"question\":\"Why are natural epigenetic therapies considered for ovarian cancer treatment?\",\"answer\":\"Because ovarian cancer mortality is linked to recurrence, metastasis, and chemoresistance that involve epigenetic aberrations in addition to genetic changes.\"},{\"question\":\"What role do omentum adipose-derived stem cells play in ovarian cancer progression?\",\"answer\":\"Omentum adipose-derived stem cells support the tumor and tumorigenic microenvironment by inducing epigenetic abnormalities and by secreting protumorigenic cytokines and growth factors that promote chemoresistance and recurrence.\"},{\"question\":\"Which natural compounds are evaluated and what are their observed effects?\",\"answer\":\"Epigallocatechin gallate (EGCG) and Indole-3-carbinol (I3C) are evaluated; they suppress growth of 3D ovarian cancer spheroids/organoids and affect proliferation, migration, invasion, and colony formation, with secretome-related changes that may reduce protumorigenic signaling.\"}]","The Effects of Natural Epigenetic Therapies in 3D Ovarian Cancer and Patient-Derived Tumor Explants: New Avenues in Regulating the Cancer Secretome | PDF",1790245037,68]
