Abstract
Considering the significance of LINC01061 in papillary thyroid cancer, here, we commenced to study the role of LINC01061 in autoimmune thyroid disease (AITD) and the potential mechanism. Thyroid tissues were attained from patients with AITD, and Nthy-ori 3-1 cells were induced with lipopolysaccharide (LPS), followed by measurement of LINC01061, microRNA (miR)-612, and BRD4 expression as well as their binding relation. The ectopic expression and silencing experimentations were carried out in LPS-induced Nthy-ori 3-1 cells to detect cell viability and apoptosis as well as inflammation and inflammasome. BRD4 and LINC01061 upregulation and miR-612 downregulation were observed in thyroid tissues of AITD patients and LPS-induced Nthy-ori 3-1 cells. Mechanistic analysis manifested that LINC01061 bound to miR-612 that negatively targeted BRD4. LINC01061 upregulated BRD4 to enhance cell viability, trigger inflammation and inflammasome activation but reduce apoptosis of LPS-induced Nthy-ori 3-1 cells by sponging miR-612. In conclusion, LINC01061 induced the occurrence of AITD by upregulation of miR-612-mediated BRD4 expression.

Abstract
Cholangiocarcinoma (CCA) is the most usual malignancy of biliary tract, possessing a relatively low overall survival rate due to limited treatment options. Recently, long non-coding RNAs (lncRNAs) have been testified to have marked regulatory impacts on human cancers. The purpose of this paper is to explore the potent regulation mechanism of LINC01061 involved in CCA. Firstly, it was observed that LINC01061 expression was heightened in CCA cell lines, whose knockdown suppressed cell proliferation, induced cell apoptosis and restrained cell migration. Besides, LINC01061 existing in the cytoplasm of CCA cells interacted with miR-612. Moreover, subsequent experiments affirmed that LINC01061 regulated SEMA4D expression by acting as a competing endogenous RNA (ceRNA) of miR-612. At last, rescue assays validated that SEMA4D overexpression restored the repression caused by LINC01061 silence on the biological activities of CCA containing cell proliferation, apoptosis and migration. To sum up, our present exploration demonstrated that LINC01061 sponges miR-612 so as to upregulate SEMA4D expression for the progression of CCA, suggesting an optional promising and effective target for the therapy of patients with CCA.

Abstract
Several DNA copy number amplifications (CNAs) have been reported in papillary thyroid cancer (PTC). However, the functional role of CNAs in PTC remains very unclear. And whether there is a correlation between long noncoding RNA (lncRNA) and CNA requires to be explored. Here, we identified a novel lncRNA LINC01061. The genomic copy number of LINC01061 is amplified, which leads to its elevated expression level in PTC tissues. Moreover, increased level of LINC01061 was correlated with aggressive clinicopathological characteristics. Functional study indicated that LINC01061 silence significantly inhibited the proliferation, cell-cycle and invasion of PTC cells in vitro and tumor growth in vivo. Mechanistically, we showed that LINC01061 interacted with miR-4316 to promote E2F6 expression. The expression of miR-4316 was downregulated in PTC tissues while that of E2F6 was upregulated. Through rescue assay, we demonstrated that LINC01061 promoted PTC cell proliferation, cell-cycle progression and invasion by regulating miR-4316/E2F6 signaling pathway. In conclusion, our research indicated that LINC01061 might be a target for PTC therapy.
