OX40Exiqon {miRada} | R Documentation

## A sample data of Exiqon microRNA microarray

### Description

A sample microRNA expression profiling data using miRCURY LNA microRNA Array based on miRbase 9.2 (Exiqon Inc., Denmark) for 40 human osteosarcoma xenograft specimens, including 10 samples for each chemotherapeutic treatment (Cisplatin, Doxorubicin, and Ifosfamide) plus 10 non-treated samples.

### Usage

      data(OX40Exiqon)

### Format

A data frame with 168192 rows and 7 columns (variables).

`Gene` | character | MicroRNA names.
`Flag` | numeric | an indictor showing the probe signal quality.
`Repeat` | numeric | an indictor showing the technical replicates.
`Treat` | numeric | treatment type: coded.
`Sample` | numeric | sample id.
`Signal` | numeric | fluorescence intensity measures
`Background` | numeric | measures of background noises
