RAB11B-AS1
RAB11B antisense RNA (RAB11B-AS1) is a long non-coding RNA which is markedly down-regulated in human osteosarcoma (OS) and associated with OS metastasis and poor prognosis.

Annotated Information
Name
RAB11B-AS1: RAB11B antisense RNA 1 (HGNC nomenclature).
Characteristics
RAB11B-AS1 locates at chromosome 19q13.2 and belongs to Ras family. RAB gene is well known for its role in tumor activation and progression [1].
Function
RAB11B-AS1 significantly facilitates proliferation, migration and invasiveness and prevents apoptosis of OS cells and results in lower sensitivity to cisplatin in these cells. In contrast, up-regulation of RAB11B-AS1 suppresses the aggressive behaviors of OS cells [1]. RAB11B-AS1 prevents osteosarcoma development and progression via inhibiting RAB11B expression, indicating RAB11B-AS1 as a potential therapeutic target for osteosarcoma [1].
Regulation
Majority of RAB11B-AS1 is shown to be localized in nucleus other than in cytoplasm of cells, suggesting the lncRNA as a transcriptional regulator in osteosarcoma cells [1].
Diseases
- Osteosarcoma (OS) [1]
Expression
Down-regulation of RAB11B-AS1 elevates its sense-cognate gene RAB11B expression at both mRNA and protein levels. RAB11B-AS1 expression correlates negatively with RAB11B expression in OS tissues [1].
