The `RPPA` dataset contains the 19Q3 CCLE Reverse Phase Protein Array (RPPA) cellular model expression data. This dataset includes data from 214 genes, 899 cancer cell lines, 28 primary diseases and 28 lineages. The columns of `RPPA` are: `depmap_id`, a foreign key corresponding to the cancer cell lineage, `cell_line` which contains the common CCLE name of the cancer cell lines, `gene` which contains the knockdown gene expression, `antibody` containing the name of knocked down gene and `expression` containing numerical protein expression data. This dataset can be loaded into R environment with the `depmap_RPPA` function.
Format
A data frame with 192386 rows and 4 variables:
- depmap_id
cancer cell line foreign key (i.e. "ACH-000001")
- cell_line
CCLE name of cancer cell line (i.e. "NIHOVCAR3_OVARY")
- antibody
Name of antibody targeting protein (i.e. "14-3-3_beta")
- expression
Observed expression via RPPA of protein coding genes
Details
This data represents the `CCLE_RPPA_20181003.csv` file taken from the 19Q3 [Broad Institute](https://depmap.org/portal/download/) cancer depenedency study. The derived dataset found in the `depmap` package features the addition of a foreign key `depmap_id` found in the first column of this dataset, which was added from the `metadata` dataset. This dataset has been converted to a long format tibble. Variables names from the original dataset were converted to lower case, put in snake case, and abbreviated where feasible.
