Emerging evidence suggests the dysregulation of long non-coding RNAs (lncRNAs) involved in pancreatic cancer (PC). However, the function of LINC00930 in PC has not been elaborated. In this study, we found that LINC00930 was significantly down-regulated in PC cell lines and tissues, and associated with tumor size, lymphatic metastasis, TNM stage and poor prognosis. According to the bioinformatics database, the downregulation of LINC00930 was a common event in PC associated with prognosis and EMT. Overexpression of LINC00930 inhibited the aggressive cancer phenotypes including proliferation, metastasis and epithelial-mesenchymal transition (EMT) of PC in vitro and in vivo. Bioinformatics and dual-luciferase reporter assay indicated that miR-6792-3p could directly bind to LINC00930. Additionally, the Zinc finger and BTB domain containing 16 (ZBTB16) was significantly declined in PC, which was predicted to be the downstream gene of miR-6792-3p. MiR-6792-3p mimic rescued the decreased proliferation, metastasis and EMT caused by ZBTB16 in PC cells. The LINC00930/miR-6792-3p/ZBTB16 axis was associated with the malignant progression and process of PC. The relative expression of LINC00930 was negatively correlated with the expression of miR-6792-3p and was closely linked with ZBTB16 levels in PC. LINC00930 might serve as a potential prognostic biomarker and therapeutic target for PC.
越来越多的证据表明,长链非编码 RNA(lncRNA)在胰腺癌(PC)中的失调。然而,LINC00930 在 PC 中的功能尚未阐述。在本研究中,我们发现 LINC00930 在 PC 细胞系和组织中显著下调,并与肿瘤大小、淋巴转移、TNM 分期和预后不良相关。根据生物信息学数据库,LINC00930 的下调是 PC 中与预后和 EMT 相关的常见事件。LINC00930 的过表达抑制了 PC 体外和体内侵袭性癌症表型,包括增殖、转移和上皮-间充质转化(EMT)。生物信息学和双荧光素酶报告基因实验表明,miR-6792-3p 可以直接结合 LINC00930。此外,锌指和 BTB 结构域包含 16 (ZBTB16)在 PC 中显著下降,预测是 miR-6792-3p 的下游基因。miR-6792-3p 模拟物挽救了 ZBTB16 引起的 PC 细胞增殖、转移和 EMT 的减少。LINC00930/miR-6792-3p/ZBTB16 轴与 PC 的恶性进展和过程有关。LINC00930 的相对表达与 miR-6792-3p 的表达呈负相关,并且与 PC 中 ZBTB16 水平密切相关。LINC00930 可能作为 PC 的潜在预后生物标志物和治疗靶点。
