Dnase I Impact on Breast Cells Co-cultured With Ovarian Cancer Cells: a Study of Cellular Interactions and Viability

Year: 2024

Type: article

Abstract: Introduction: Cell-free DNAs (cf-DNAs) are released into the bloodstream through cell apoptosis, necrosis, or active secretion, often originating from cancer cells. These cf-DNAs have been associated with cancer development and metastasis, although their precise role remains under debate. DNase I, an enzyme that degrades extracellular DNA, has shown potential to impact cf-DNAs and influence cancer progression. This study investigates the effects of ovarian cancer cells on the proliferation and viability of non-tumorigenic breast cells, with a focus on DNase I’s role. Materials and Methods: Human ovarian cancer cells (OVCAR-3) and normal human breast cells (MCF-10A) were cultured under standard conditions (37°C, 5% CO₂). Co-culture experiments were conducted by incubating cells separately in plates and inserts, with or without DNase I, for 72 hours. Cell viability was assessed using the trypan blue exclusion test, while proliferation and adhesion were measured with an XTT assay. Results: DNase I significantly reduced OVCAR-3 proliferation (p
