miRNA expression data from oral squamous cell carcinoma patients

Oral squamous cell carcinoma (OSCC) accounts for the high mortality rate and morbidity in head and neck cancer. Data for analysis were obtained from the microarray data of 6 OSCC tissues, tissues adjacent to cancer, and contralateral normal tissues.We used the affy package under the R environment to preprocess and normalize the original gene chip data. Data for analysis were obtained from the microarray data of 6 OSCC tissues, tissues adjacent to cancer, and contralateral normal tissues. We used the affy package under the R environment to preprocess and normalize the original gene chip data. Differentially expressed genes were obtained by pre-processing gene expression profile data to construct a weighted gene co-expression network and identify key gene modules.
