Sanguinarine inhibits the proliferation of BGC-823 gastric cancer cells via regulating miR-96-5p/miR-29c-3p and the MAPK/JNK signaling pathway

In this study, the in vitro proliferation inhibition effect of SAN in GC cells was determined using CCK-8 assay, the in vivo antitumor effect of SAN was evaluated in mice with xenotransplanted tumor. The mechanism underlying the antitumor activity of SAN was explored by gene microarray assay and bioinformatics analysis. The levels of differentially expressed miRNAs and target genes were verified by real-time RT-PCR and immunohistochemistry. SAN inhibited the proliferation of BGC-823 cells in a concentration-dependent manner in vitro and in vivo. The miR-96-5p and miR-29c-3p were significantly upregulated in untreated BGC-823 cells and significantly downregulated in SAN treated cells. The mRNA and protein expression of their target gene MAP4K4 were upregulated in SAN treated xenotransplanted tumors, and pMEK4 and pJNK1 proteins in the MAPK/JNK signaling pathway were also upregulated by SAN. These indicate that SAN may inhibit the proliferation of BGC-823 cells through the inhibition of miR-96-5p and miR-29c-3p expression, and subsequent activation of the MAPK/JNK signaling pathway.

We report a case of a 37-year-old man with a history of recurrent episodes of vomiting and long-standing type 2 diabetes mellitus. Esophagogastroduodenoscopy did not reveal any findings of reflux esophagitis or obstructive lesions. A gastric emptying time scan showed prolonged gastric emptying half-time (344 minutes) indicating delayed gastric emptying. Laboratory tests revealed elevated fasting serum glucose and glycosylated hemoglobin (HbA1c, 12.9%) and normal fasting C-peptide and insulin levels. We performed Roux-en-Y reconstruction after subtotal gastrectomy to treat gastroparesis and improve glycemic control, and the...

This study evaluated the safety and feasibility of MBBT in patients undergoing TLDG. Thirty-three patients who underwent TLDG with MBBT were retrospectively evaluated. The mean operation time was 277.6±37.1 minutes, including 51.9±15.7 minutes for reconstruction. Two patients had anastomosis-related complications, one patient with stricture after leakage and 1 patient with stenosis. The former patient was treated with endoscopic balloon dilatation, and the latter was managed conservatively; neither required re-operation. MBBT is a safe and feasible technique, with acceptable surgical outcomes. It may be a goo...

Authors: Kim SH, Lee HJ, Park JH, Choi JH, Park SH, Choe HN, Oh SY, Suh YS, Kong SH, Park DJ, Yang HK Abstract Purpose: Gastric cancer with lymph node metastasis (LNM) more than 15 (N3b) was defined as stage IV until the 6th AJCC system. However, it has been reclassified as a localized disease (stage IIb or III) since the 7th system. The aim of this study is to demonstrate that the survival of N3b is comparable to cytology-only positive (CY1-only) stage IV and to propose a new TNM system interpreting N3b as an eligibility criterion for receiving more intensive chemotherapy regimens. Materials and Methods: 1,430...

Conclusions: We identified exosomal miRNAs capable of distinguishing between non-malignant and GC-ascites, showing that the combined use of miR-181b-5p and CEA could improve diagnosis. PMID: 31598373 [PubMed]
