Microarray based global gene expression profiling.
(a) Analysis pipeline utilised for identification of differentially expressed genes between sample groups. (b) Venn diagram depicting the number of genes differentially expressed among the low and high HOTAIR CaCx cases. (c) Hierarchical clustering distinctly separating the CaCx cases from the histopathologically normal controls (HPV negative and HPV16 positive) based on the differentially expressed genes.
