Kruppel-like factor 4 (KLF4), Death-associated protein kinase 1 (DAPK1) and Spastic Paraplegia 20 (SPG20) methylation increase significantly in FL and DLBCL compared to follicular hyperplasias.
In the present study, spastic paraplegia 20 (SPG20) promoter-methylated DNA, as a potential diagnostic biomarker, was investigated in plasma and tumor tissue samples from patients with CRC.
Additionally, the expression of Spartin, the protein product encoded by spastic paraplegia-20, was analyzed in tissues from 119 gastric cancer patients who underwent radical gastrectomy at Xi'an Jiaotong University between 2005 and 2010.
Here, we show that the SPG20 (spastic paraplegia-20) promoter, encoding the multifunctional Spartin protein, is hypermethylated in 89% of colorectal carcinomas, 78% of adenomas and only 1% of normal mucosa samples.
