Leuk_miR_full: microRNA expression of acute leukemia phenotypes (full dataset)

Description

Data of human microRNA (miR) expression of 847 miRs from 80 acute myeloid (AML) and acute lymphoblastic (ALL) leukemia cell lines, 60 primary (patient) samples, and 50 normal control samples sorted by cell type (CD34+ HSPC, Granulocytes, Monocytes, T-cells and B-cells). Acute lymphoblastic leukemia samples are further classified by B-cell (B-ALL) and T-cell (T-ALL) subphenotypes.

Format

The full dataset Leuk_miR_full consists of a numerical matrix of expression (with samples as rows and miRs as columns) and two data frames with sample and miR metadata.

Details

Data available at GEO under Accession Number GSE51908.
