IATPR
IATPR is a long non-coding RNA and could be a potential biomarker in the prognosis of breast cancer.

Annotated Information
Name
Approved symbol：IATPR
Approved name：ITGB1 adjacent tumor promoting lncRNA
HGNC ID ：HGNC:53719
Alias symbol：TCONS_00018476|linc-ITGB1
RefSeq ID：NR_160030
Characteristics
IATPR has a chromosomal location of 10p11.22 (HGNC data).
Function
Functional analysis shows that knockdown of IATPR significantly inhibits gallbladder cancer cell proliferation [1]. IATPR potentially promotes gallbladder cancer invasion and metastasis by accelerating the process of epithelial-to-mesenchymal transition, and the application of RNA interference targeting linc-ITGB1 might be a potential form of gallbladder cancer treatment in advanced cases [1]. IATPR also promotes breast cancer progression by inducing cell cycle arrest and interrupting the epithelial-to-mesenchymal transition process [2].

Expression
IATPR levels were lower in tumor tissues of BC patients in comparison to adjacent non-cancerous breast tissues (p < 0.001). Linc-ITGB1 expression was significantly associated with lymph node metastasis, pathological differentiation and TNM stage (all p < 0.05) [3]. However, further studies are required to establish lincRNA-ITGB1 expression and clinicopathological features in GBC cases [1].
