Abstract
This study investigates the relationship between intracellular eumelanin content and proliferation of melanoma cells derived from pet murine under ultraviolet (UV) radiation. B16F10 cells, a murine melanoma cell line established from pet murine models, were exposed to UV doses ranging from 0 to 2,880 J/m2. Cell proliferation was assessed using the CCK-8 assay, while intracellular eumelanin content was quantified via microplate reader after cell lysis, normalized using BCA protein quantification. Linear regression was performed using partial regression analysis revealed a positive correlation between eumelanin content and cell proliferation at low-to-moderate UV doses. However, this linear relationship was disrupted at the highest dose. Protein-protein interaction (PPI) analysis further demonstrated that PIAS3, a regulatory protein, modulates both STAT3 and MITF, key factors in melanoma progression. These findings suggest that UV exposure enhances eumelanin production and proliferation in pet murine melanoma cells at sub-lethal doses, but excessive UV exposure may disrupt this balance, potentially through downregulation of PIAS3. The results highlight the dual role of UV radiation in promoting eumelanin synthesis as a protective mechanism while also driving tumor growth, offering insights into the pathogenesis of melanoma in pet murine and underscoring the importance of UV protection in their clinical management.
