The novel long noncoding RNA lncRNA-AU021063, induced by IL-6/Arid5a signaling, exacerbates breast cancer invasion and metastasis by stabilizing Trib3 and activating the Mek/Erk pathway (mRNA-Seq)

Project description:Interleukin (IL-6) is a pleotropic cytokine with both tumor-promoting and -inhibitory effects on breast cancer growth. However, the mechanisms governing the outcome of IL-6 on cancer progression remain to be clarified. Our study unraveled a novel long noncoding RNA (lncRNA)-AU021063 downstream of IL-6 signaling. We found that IL-6 induced the expression of lncRNA-AU021063 predominantly in breast cancer compared to other cancer types. Mechanistically, IL-6 induced AT-rich interactive domain 5a (Arid5a) expression, which promotes the transcription of lncRNA-AU021063. In turn, lncRNA-AU021063 promotes breast cancer metastasis through stabilizing tribbles homolog 3 (Trib3) and activating Mek/Erk signaling pathway. Genetic ablation of either Arid5a, lncRNA-AU021063 or Trib3 abolished breast cancer metastasis in vitro and in vivo. Overall, our study highlights the importance of IL-6-Arid5a-lncRNA-AU021063 axis in regulating breast cancer invasiveness and metastasis, which may provide potential novel therapeutics for breast cancer.

Dichotomous roles of Arid5a augment the immunosuppressive microenvironment of mesenchymal malignant tumors

Project description:Although mesenchymal subtypes of pancreatic ductal adenocarcinoma (PDAC) and colorectal cancer (CRC) are known as “immunologically cold” tumors, the molecular link between tumor immune evasiveness and mesenchymal phenotype remains largely unknown. Here, we show that AT-rich interaction domain-containing protein 5a (Arid5a), an RNA-binding protein, is involved in immune evasion in PDAC and CRC mouse models. Mass cytometry demonstrated that in tumors from Arid5a-deficient cells, the infiltration of granulocytic myeloid-derived suppressor cells and regulatory T cells is suppressed, but cytotoxic T-lymphocyte recruitment is enhanced. Mechanistically, Arid5a augmented Ido1 and Ccl2 expression by stabilizing these mRNAs in the PDAC model, but not Ido1 in the CRC model. Furthermore, Arid5a expression was substantially increased in mesenchymal subtypes of PDAC and CRC, mediated by ZEB1, and Arid5a promoted TGF-b-induced and IL6-induced epithelial-mesenchymal transition and acquisition of invasiveness in PDAC model cells. Thus, our findings demonstrate that Arid5a is a promising target for immunotolerant malignant tumors.
