The ratio of apoptotic cells was increased by RAI2 under STS treatment in CRC cells

The ratio of apoptotic cells was increased by RAI2 under STS treatment in CRC cells. (mm), and represents the smallest diameter (mm). Mice were sacrificed on the 22nd day, and tumor weights were measured. All procedures were approved by the Animal Ethics Committee of the Chinese PLA General Hospital. Statistical analysis The RNA sequencing (RNA-Seq) data for RAI2 gene expression in the dataset of CRC and normal tissues were downloaded from Genotype-Tissue Expression (GTEx) database ( and the Cancer Genome Atlas (TCGA) (, 08/16/2016), respectively. Statistical analysis was performed using SPSS 17.0 software (SPSS, Chicago, IL). Chi-square or Fishers exact tests were used to evaluate the relationship between methylation status and clinical pathological characteristics. The two-tailed independent samples test was applied to determine YH239-EE the statistical significance of the differences between the two experimental groups. Survival rates were calculated by the Kaplan-Meier method, and the differences in survival curves were evaluated using the log-rank test. Cox proportional hazards models were fit to determine independent associations of RAI2 methylation with 5-year OS and 5-year relapse-free survival (RFS) outcomes. Two-sided tests were used to determine the significance, and valuevalues are obtained from the chi-squared test Statistically significant *P?P?P?

Methylation of RAI2 was analyzed by Illumina Infinium Human Methylation 450 (HM450) based on the methylation status of 16 CpGs in the promoter region. Available data were obtained from 373 cases of colorectal cancer samples for both RAI2 expression YH239-EE and methylation. The expression of RAI2 was inversely associated with promoter region methylation (P?P?
