ZFP36L1 Promotes Gastric Cancer Progression via Regulating JNK and p38 MAPK Signaling Pathways.
Background: The RNA-binding protein Zinc Finger Protein 36 like 1(ZFP36L1) plays an important role in regulating the AU-rich elements (AREs) in the 3' untranslated region (3' UTR) of mRNAs, indicating a potential link between its expression and cancers. However, the role and mechanism of ZFP36L1 in gastric cancer (GC) are unclear.
Objectives: This study aimed to explore the role and mechanism of ZFP36L1 in gastric cancer.
Materials and methods: GC tissue samples and matched normal gastric tissues were collected, and the ZFP36L1 expression in these samples was evaluated by immunohistochemistry analysis. GC cells with different differentiation were selected for in vitro experiments. The ZFP36L1 expression in GC cells was examined by quantitative real-time polymerase chain reaction (qRTPCR) and Western blot analysis. The viability and invasiveness of GC cells were assayed by 5- Ethynyl-2-deoxyuridine (EdU) and Transwell assays, respectively. Western blot assay was used to detect the expression of epithelial-to-mesenchymal transition (EMT) related proteins and proteins of the c-Jun N-terminal kinase (JNK) and p38 Mitogen-Activated Protein Kinase (MAPK) signaling pathways.
Results: ZFP36L1 is overexpressed in GC tissues. Patients with high ZFP36L1 expression have a poor prognosis. Moreover, ZFP36L1 is overexpressed in the cell lines with a high degree of malignancy. ZFP36L1 increases cell proliferation, invasion, and migration in vitro. Furthermore, ZFP36L1 induces EMT. The JNK inhibitor and p38 inhibitor alone or in combination affect the biological function of GC cells. Furthermore, ZFP36L1 promotes GC progression by inhibiting JNK and p38 MAPK signaling pathways.
Conclusion: RNA-binding protein ZFP36L1 exerts a role in the occurrence of gastric cancer by the regulation of the JNK and p38 MAPK signaling pathways. The combination of inhibitors of the JNK and p38 MAPK signaling pathways could be a novel treatment strategy for gastric cancer.

Aims & Scope
Recent Patents on Anti-Cancer Drug Discovery publishes review and research articles that reflect or deal with studies in relation to a patent, application of reported patents in a study, discussion of comparison of results regarding application of a given patent, etc., and also guest edited thematic issues on recent patents in the field of anti-cancer drug discovery e.g. on novel bioactive compounds, analogs, targets & predictive biomarkers & drug efficacy biomarkers. The journal also publishes book reviews of eBooks and books on anti-cancer drug discovery. A selection of important and recent patents on anti-cancer drug discovery is also included in the journal. The journal is essential reading for all researchers involved in anti-cancer drug design and discovery. The journal also covers recent research (where patents have been registered) in fast emerging therapeutic areas/targets & therapeutic agents related to anti-cancer drug discovery.
