Figure 2.

DNA copy number and mRNA levels of HDAC1 in LUAD. The DNA copy number data were not statistically significant, while the mRNA expression level was significantly higher than that of normal tissue, according to Oncomine analysis, showing fold change, associated P values, and the ranking of overexpressed genes. The (a)–(b) figures show the copy number of HDAC1 in the tumor genome atlas (TCGA) lung 2 and Weiss Lung datasets, respectively. The (c)–(f) figures show the data of the gene expression chip in the GEO database of HDAC1 mRNA levels in Okayama Lung, Garber Lung, Hou Lung, and Beer Lung, respectively.
