Dataset notes
Sample information and limitations Two selected acquisitions, one working-mapped A_1 and one A_3. The mapping source is user-shared information rather than an independent PRIDE confirmation; animal identity, pooling and biological/technical repetition remain unresolved. Only descriptive log2(A_3/A_1) direction is reported; no P value or FDR is valid from these files alone.
Experimental metadata notes Epirubicin-treated parental versus epirubicin-resistant UM-UC-3 CDX-derived cells. Conditional working map used only for exploratory analysis, based on user-shared information and not independently confirmed in the article/PRIDE: A_1=parental+EPI; A_3=resistant+EPI. This is resistant-versus-parental under a shared EPI background, not EPI versus untreated.
