AFDN-DT
AFDN-DT, an lncRNA that is repressed in gastric cancers (GC), functions as a tumour suppressor by inhibiting cell growth and metastasis through transcriptional repression of genes involved in metastasis and DNA hypermethylation could repress AFDN-DT expression.

Characteristics
AFDN-DT is two exon transcript of 2311 bp (GenBank) long non-coding RNA, located on human chromosome 6q27 [1].2.2 kb; spliced, polyadenylated and comprised of 6 exons in humans [1].
Function
Decreased expression of AFDN-DT is associated with a poor prognosis in gastric cancer [1].
Expression
DNA hypermethylation could repress AFDN-DT expression.[2]
AFDN-DT is significantly downregulated in gastric cancer tissue compared with normal adjacent tissue [1].
