Fig. 7: Cellular population analysis and cuproptosis in PD and melanoma.

A xCell analysis showing a significant reduction in neuronal populations in PD tissues. B, C xCell analysis indicating decreased neuronal and melanocyte populations in melanoma tissues. D Association of hub genes with neuronal populations in PD. E Association of hub genes with melanocyte populations in melanoma. F Elevated cuproptosis levels in PD neurons. G Elevated cuproptosis levels in melanoma melanocytes. H Sankey diagram illustrating the relationships between hub genes and cuproptosis in PD neurons. I Sankey diagram illustrating the relationships between hub genes and cuproptosis in melanoma melanocytes.
