Approved Name
lncARSR: lncRNA regulator of Akt signaling associated with HCC and RCC
Characteristics
lncARSR (lncRNA Activated in RCC with Sunitinib Resistance) is located on chromosome 9 in humans and composed of four exons with a full length of 591 nt determined by RACE. [1]
Function
lncARSR acts as a ceRNA for miR-34 and miR-449 to promote AXL and c-MET expression [1] . lncARSR promotes the self-renewal capacity, tumorigenicity and metastasis of renal T-ICs [2]. lncARSR plays a critical role in renal T-ICs propagation and may serve as a prognostic biomarker and potential therapeutic target [2]. lncARSR physically associates with PTEN mRNA, promotes PTEN mRNA degradation, decreases PTEN expression, and activates PI3K/Akt pathway [3]. Long noncoding RNA lncARSR promotes hepatic lipogenesis via Akt/SREBP-1c pathway and contributes to the pathogenesis of nonalcoholic steatohepatitis [4]. Upregulated lncARSR promotes hepatic cholesterol biosynthesis via modulating Akt/SREBP-2/HMGCR pathways [5]
Regulation
Transfection of constitutively active FOXO1 (FOXO1-A3) or FOXO3a (FOXO3a-A3) significantly downregulated lncARSR levels in sunitinib-resistant cells [1]
Diseases
Expression
lncARSR is preferentially upregulated in renal T-ICs [2] . lncARSR is upregulated in HCC, associated with large tumor size and advanced BCLC stage [3]. Overexpression of lncARSR enhance while knockdown of lncARSR ameliorated hepatic lipid accumulation in vivo and in vitro [4].
