Type 2 diabetes mellitus (T2DM) is a metabolic disease with an increasing incidence worldwide, which leads to damage to various tissues and organs including the liver. MiR-31 is conserved across species and closely associated with metabolic diseases, but its role in type 2 diabetic liver injury has not been elucidated. This study aimed to investigate the effect of miR-31 on liver injury in type 2 diabetes and its underlying mechanism. Four to six weeks old male FVB mice and miR-31-positive transgenic mice were randomly divided into FVB mice control group (C), FVB mice induced diabetes group (DM) and miR-31-overexpression transgenic mice induced diabetes group (31DM). After 1 week of adaptive feeding, the T2DM mouse model was induced by high-fat feeding combined with intraperitoneal injection of streptozotocin (STZ) for 6 weeks. The general condition of mice and related metabolic indicators showed that the increased food and water intake, weight loss and glucose and lipid metabolism disorders could be reversed by miR-31 in T2DM mice. HE staining and liver histological activity index (HAI) scoring results showed that miR-31 improved the inflammatory status in the liver tissue of T2DM mice and decreased the HAI score. RT-qPCR results showed that the high expression of miR-31 was accompanied by a decrease in the expression of activating transcription factor 6 (ATF6) mRNA in the liver of T2DM mice. Furthermore, Western blotting results showed that miR-31 inhibited the expression of endoplasmic reticulum stress-related proteins such as ATF6, glucoregulatory protein 78 (GRP78) and C/EBP homologous protein (CHOP) in the liver of T2DM mice. In conclusion, miR-31 may ameliorate liver injury in T2DM mice by regulating glucose and lipid metabolism disorders and insulin resistance, and inhibiting endoplasmic reticulum stress factors such as ATF6, GRP78, and CHOP.
ABSTRACT
Breast cancer is a malignant tumor with high mortality, and multidrug resistance (MDR) mediated by ABCG2 (ATP-Binding cassette G2) is an important cause of chemotherapy failure. It is an urgent problem to explore the mechanism of ABCG2-mediated drug resistance and its key molecules. Epithelial cell adhesion molecule (EpCAM) is involved in multiple tumor drug resistance and is closely related to breast cancer MDR. However, its role in ABCG2-mediated breast cancer drug resistance has not been clarified. The purpose of this study was to explore the regulation of EpCAM on ABCG2-mediated MDR in breast cancer cells and its mechanism. CCK8 cytotoxicity assays confirmed that the drug resistance of MCF-7/MX cell line to mitoxantrone (MX) was significantly increased compared with MCF-7 drug-sensitive strain of human breast cancer. Western blotting results showed that ABCG2 was highly expressed and EpCAM was up-regulated in MCF-7/MX cells compared with MCF-7. SiRNA knockdown of EpCAM in MCF-7/MX cells down-regulated ABCG2 expression and restored sensitivity to MX. Cell morphology was observed under an inverted microscope, and it was found that knocking down EpCAM reduced cell-cell connections between MCF-7/MX cells. The co-localization of EpCAM and claudin 1 in MCF-7/MX cells was observed by immunofluorescence. Furthermore, Western blotting results showed that EpCAM knockdown reduced claudin 1 expression in MCF-7/MX cells. In conclusion, EpCAM may promote ABCG2-mediated mMDR in breast cancers by enhancing intercellular tight junctions through interaction with claudin 1.
ABSTRACT
Aim To investigate the role of aberrant cytokeratin 18(CK18) expression in breast cancer metastasis, anrl to elucidate the mechanism by identif¬ying its target.Methods The expression of CK.18 in human breast cancer tissues and cells was determined using immunohistochemical staining and Western blot, respectively.CK18 expression in human breast cancer MCF-7 cells was effectively down-regulated by shRNA, and its effect on breast cancer metastasis was further determined by scratch wound healing assay.The co-lo- cation of CK18 and non-muscle II A ( NMIIA) in MCF-7 cells was examined using double immunofluo¬rescence staining.The effect of CK18 down-regulation on the levels of NMIIA and c-Abl-ERK signaling was quantified by Western blot.Results Lower CK18 lev¬els was found in metastatic than that in primary breast cancer tissues and in highly invasive MDA-MB-231 than that in MCF-7 cells.CK.18 down-regulation pro¬moted the wound repair ability of MCF-7 cells 72h after scratch.CK18 and NMIIA were shown to co-locate in cytoplasm of MCF-7 cells.Moreover, down-regulation of CK18 increased NMIIA expression and activated the c-Abl-ERK signaling pathway in MCF-7 cells.Con¬clusions Down-regulation of CK18 could promote me¬tastasis of breast cancer, which is related to increased NMIIA expression and the activation of c-Abl-ERK sig¬naling pathway.
ABSTRACT
Aim: To investigate the effect of epithelial cell adhesion molecule (EpCAM) on metastasis and multidrug resistance of breast cancer and its mechanism. Methods Immunohistochemical staining was employed to detect the expression of EpCAM in adjacent non-tumor tissues (ANTTs) and breast cancer tissues. siRNA was applied to knock down EpCAM expression in MDA-MB-231 cells. Transwell assay was used to detect the invasion and migration ability of breast cancer cells. Western blot analysis was performed to determine the protein expression of EpCAM, epithelial mesenchymal transition (EMT) markers E-cadherin, N-cadherin and vimentin, breast cancer resistance protein (BCRP), and β-catenin. Results EpCAM immunoreactivity was consistently stronger in primary breast cancer tissues and even higher in metastatic lesions than that in ANTTs. The expression of EpCAM was significantly upregulated in triple negative breast cancer MDA-MB-231 cells. EpCAM knockdown using siRNA decreased the invasion and migration ability and BCRP expression, and partially reversed the EMT phenotypes of MDA-MB-231 cells, β-catenin expression was upregulated in MDA-MB-231 cells. ICG-001, a specific Wnt/β-catenin pathway inhibitor, downregulated the expression levels of EpCAM, N-cadherin, and vimentin in MDA-MB-231 cells. Conclusions EpCAM could promote metastasis and drug resistance of breast cancer through the induction of EMT, which is related to the Wnt/β-catenin signaling pathway.
ABSTRACT
Objective: To observe the effects of electroacupuncture (EA) of different frequencies on transmission function, electromyography, nitric oxide synthase (NOS) content and interstitial cells of Cajal (ICC) expression of colon in rat models with slow transit constipation (STC). Methods: Of the 50 healthy male Wistar rats, 10 were randomly selected as a normal group and fed with ordinary diet, and the remaining 40 rats were fed with the diet added with the compound diphenoxylate at a dose of 8 mg/(kg·bw) each day for continuous 120 d. The 40 successfully established STC rat models were randomly divided into a model group, a low-frequency EA group (2 Hz), a high-frequency EA group (100 Hz), and a variable-frequency EA group (2 Hz/100 Hz), with 10 rats in each group. Rats in the normal and the model groups were not given any treatment; the low-frequency EA and the high-frequency EA groups were given EA at Tianshu (ST 25), Zusanli (ST 36) and Zhigou (TE 6) with continuous wave at the designated frequency, and the variable-frequency EA group received sparse-dense wave (2 Hz/100 Hz) EA at the same acupoints, once a day for a total of 15 d. After treatment, the colonic transmission function, electromyography, NOS content and ICC expression (calculated by the difference in the area of the C-kit positive cells) of the rats in each group were measured. Results: For the colonic transmission function, compared with the normal group, the first black stool excretion durations of rats in the other groups were significantly prolonged (all P<0.05); compared with the model group, the first black stool excretion durations of rats in the three EA groups were significantly shortened (all P<0.05), which was significantly shorter in the variable-frequency EA group than in the low-frequency EA and high-frequency EA groups (both P<0.05). For the colonic electromyography, compared with the normal group, the amplitude was significantly increased and the frequency was accelerated in rats of the other groups (all P<0.05); compared with the model group, the amplitude was significantly reduced and the frequency was slowed down in the three EA groups (both P<0.05); compared with the low-frequency EA and the high-frequency EA groups, the amplitude was reduced and the frequency was significantly reduced in rats of the variable-frequency EA group (both P<0.05). Compared with the normal group, the colonic NOS contents were significantly increased in the other groups (all P<0.05); compared with the model group, the NOS contents were significantly reduced in the three EA groups (all P<0.05); compared with the low-frequency EA and the high-frequency EA groups, the content was significantly reduced in the variable-frequency EA group (all P<0.05). For the area of rat colonic C-kit-positive cells, compared with the normal group, the areas were significantly reduced in rats of other groups (all P<0.05); compared with the model group, the areas were increased significantly in the three EA groups (all P<0.05); compared with the low-frequency EA group, the area was increased significantly in the variable-frequency EA group (P<0.05). Conclusion: EA, especially EA at the 2 Hz/100 Hz variable-frequency, has a positive treatment effect on the STC model rats. It may improve rats' colonic function by regulating the electromyography, NOS content and ICC expression of colon.
