The objective of the present study was to clarify the expression characteristics of long non‑coding RNA (lncRNA) FGD5 antisense RNA 1 (FGD5‑AS1) in pancreatic cancer, as well as its biological function and underlying mechanism. Reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) was utilized for the detection of FGD5‑AS1 and microRNA (miR)‑577 expression levels in pancreatic cancer tissues. Transfection was performed to upregulate or downregulate FGD5‑AS1 in pancreatic cancer cell lines. MTT and Transwell assays were then utilized to detect the proliferation, migration and invasion of cancer cells, respectively. Subsequently, dual‑luciferase reporter gene assay, RNA immunoprecipitation assay, RNA pull‑down assay, RT‑qPCR, western blotting, and Pearson's correlation analysis were employed to confirm the regulatory relationships among FGD5‑AS1, miR‑577, low‑density lipoprotein receptor‑related protein 6 (LRP6) and β‑catenin. Western blotting was employed to determine the expression levels of Axin2, cyclin D1 and c‑Myc. The expression level of FGD5‑AS1 was upregulated in pancreatic cancer tissues and cell lines. FGD5‑AS1 knockdown inhibited pancreatic cancer cell proliferation, migration and invasion. By contrast, miR‑577 was significantly inhibited in pancreatic cancer cells and tissues; its downregulation promoted pancreatic cancer cell proliferation, migration and invasion, and reversed the effects of FGD5‑AS1 knockdown on pancreatic cancer cells. In addition, it was revealed that miR‑577 was a target of FGD5‑AS1, and FGD5‑AS1 could modulate the expression levels of LRP6, β‑catenin, Axin2, cyclin D1 and c‑Myc via suppressing miR‑577. In conclusion, in pancreatic cancer, highly expressed FGD5‑AS1 activated the Wnt/β‑catenin signaling and promoted cancer cell proliferation, migration and invasion via suppression of miR‑577.

In this study, a new Cd(II)-bearing coordination polymer with the chemical formula of {[Cd 4 (meda) 3 (dpe) 4 (H 2 O) 4 ]·(NO 3 ) 2 ·2(H 2 O)} n (1, H 2 meda = 3,3'-methylenedibenzoic acid, dpe = 1,2-di(pyridin-4-yl)ethane) has been successfully prepared by reaction of Cd(NO 3 )·4H 2 O with a V-shape carboxyl ligand H 2 meda along with the linear dipyridine ligand dpe under the hydrothermal conditions. Due to its intensive luminescence, complex 1 could be utilized as the sensor of detecting Al 3+ ion, and its detection limit is 4 × 10 -6  M. Firstly, the toxicity of the compound on the normal liver cells was determined with Cell Counting Kit-8 detection kit. The triglyceride in liver cells was detected by detection kit after compound treatment and the relative expression of 15-lox and 12-lox in L02 cells was also measured by RT-PCR after compound treatment. In addition, multiple functional groups that provided by the synthesized Cd(II) complex have been studied by using molecular docking simulation for the confirmation of possible binding modes that formed between ligand and receptor.

Aims: The relationship between diabetes mellitus and pancreatic cancer risk from is uncertain based on the results of existing publications. The current report updated and re-evaluated the possible association between diabetes mellitus and pancreatic cancer risk in China., Methods: Six databases (PubMed, Embase, Web of Science, the Cochrane Library, the Chinese Biomedical Database, and the Chinese National Knowledge Infrastructure) were used for the literature search up to October 2017., Results: Twenty-six case-control studies involving 7702 pancreatic cancer cases and 10186 controls were screened out. The overall summary estimate for the relationship between diabetes and pancreatic cancer was 3.69 (95% CI, 3.12-4.37). The subgroup analysis indicated positive associations among northern and southern Chinese, as well as studies with healthy population or hospital controls. In addition, the risk of developing pancreatic cancer was inversely associated with the duration of diabetes, with the highest risk of pancreatic cancer occurring among patients with diabetes <2years. Individuals who had diabetes <2years had a >2-fold higher risk of developing pancreatic cancer than individuals who had diabetes for 2-4years or 5-10years (OR, 4.92; 95% CI, 4.16-5.80 vs. OR, 1.92; 95% CI, 1.30-2.85/OR, 2.14; 95% CI, 1.49-3.09)., Conclusions: This meta-analysis strongly supports that an association exists between diabetes and an increased risk of pancreatic cancer in China, which should be confirmed with other ethnic groups., (Copyright © 2018 Primary Care Diabetes Europe.
