HDAC1 and non-small cell lung carcinoma: Combining our previous results showing that X-radiation upregulates Axin expression in some NSCLC tissues, we suggest that X-radiation may inhibit HDAC1 and HDAC2 expression and weaken the inhibitory effect of HDAC1 and HDAC2 on Axin, thereby upregulating Axin expression and inducing apoptosis of cancer cells.
