GxA Get Experiment Expression

Get gene expression data from a specific Expression Atlas experiment. Returns expression levels across tissues or conditions, with optional filtering by gene ID. Experiment E-MTAB-2836 contains RNA-seq of 122 human tissues, E-MTAB-2706 covers 675 cancer cell lines. For each gene, expression values are provided across all assayed conditions (tissues, cell types, developmental stages, etc.).
