Aberrant expression of Jagged1 and Notch1 are associated with poor outcome in breast cancer. However, the reason that Jagged1 and/or Notch overexpression portends a poor prognosis is unknown. We identify Slug, a transcriptional repressor, as a novel Notch target and show that elevated levels of Slug correlate with increased expression of Jagged1 in various human cancers. Slug was essential for Notch-mediated repression of E-cadherin, which resulted in β-catenin activation and resistance to anoikis. Inhibition of ligand-induced Notch signaling in xenografted Slug-positive/E-cadherin–negative breast tumors promoted apoptosis and inhibited tumor growth and metastasis. This response was associated with down-regulated Slug expression, reexpression of E-cadherin, and suppression of active β-catenin. Our findings suggest that ligand-induced Notch activation, through the induction of Slug, promotes tumor growth and metastasis characterized by epithelial-to-mesenchymal transition and inhibition of anoikis.

This study investigated the prognostic value of the long non-coding RNA (lncRNA) LINC01586 in pancreatic cancer. Three pancreatic cancer patients who received pancreaticoduodenectomies in our department in January 2019 were retrospectively selected. Cancer tissue and adjacent tissue samples were collected for high-throughput sequencing of lncRNAs. Among them, 221 lncRNAs were up-regulated and 235 were down-regulated. The expression of LINC01586 was decreased in pancreatic cancer patients (logFC = -3.308). An additional 74 tissue specimens were collected from pancreatic cancer patients from January 2011 to December 2016 for low-throughput validation. Patient samples were categorized into overexpression and low expression groups, based on the median LINC01586 expression level. The LINC01586 low expression group exhibited larger tumor size than the overexpression group (P < 0.001), while the low expression group exhibited a lower cancer-related survival rate than the overexpression group (one-year cancer-related survival rate: 55.6% vs. 89.2%, P < 0.001). Further analysis confirmed that low expression of LINC01586 was associated with poor prognosis for pancreatic cancer patients (OR = 0.169, 95% CI 0.066-0.437, P = 0.000). KEGG signaling pathway analysis was used to enrich LINC01586 target genes, and were mainly related to two metabolic pathways: insulin secretion (P = 0.011) and dopaminergic synapses (P = 0.0129), with SNAP25 as the core gene. The expression of LINC01586 and SNAP25were positively correlated in pancreatic cancer (R = 0.81 and P < 0.001). Together, our results indicate that LINC01586 may be used as a biomarker for prognosis predictions in pancreatic cancer patients, and its low expression is associated with poor prognosis.
