MicroRNAs (miRNAs) are a class of non-protein-coding small RNAs with the capacity to regulate fundamental biological processes essential for cancer initiation and progression. In the present study, we analyzed miRNA expression levels between multidrug-resistant gastric carcinoma cell line SGC7901/ADR and its parent cell line SGC7901 using a miRNA(More)
Growing evidence has revealed that microRNAs could regulate the proliferation of pancreatic ductal adenocarcinoma (PDAC) cells and predict the prognosis of PDAC. Here the comparative microRNA expression profiles of the good and poor prognosis groups were performed by microRNA microarray. MicroRNA-891b (miR-891b) was screened and validated to be a prognostic(More)
Trastuzumab has recently been recommended for the treatment of epidermal growth factor receptor-2 (HER2)-positive advanced gastric cancer in combination with the capecitabine/cisplatin (XP) versus continuous infusion of 5-fluorouracil/cisplatin (FP) regimen. However, it is unclear whether it is rational to combine trastuzumab with other chemotherapy(More)
Studies have shown that tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) selectively induces apoptosis in cancer cells. However, breast cancer cells are generally resistant to TRAIL. In the present study, we explored the effect of bufalin on TRAIL-induced breast cancer cell apoptosis. The results showed that bufalin enhanced TRAIL-induced(More)
Bufalin, a cardiotonic steroid isolated from toad venom, has been shown to kill various types of tumor cells. Our previous study showed that triple-negative breast cancer (TNBC) cells were less sensitive to bufalin than other types of breast cancer cells, but the reason for this lower sensitivity remains unclear. In this study, we showed that bufalin(More)
The epithelial-to-mesenchymal transition (EMT) is a well-known prerequisite for cancer cells to acquire the migratory and invasive capacity, and to subsequently metastasize. Bufalin is one of the major active components of the traditional Chinese medicine Chan Su, and accumulating evidence has shown its anticancer effect in multipe types of cancer. However,(More)
BACKGROUND Several studies have shown that platelet-to-lymphocyte ratio (PLR) is a prognostic factor for various cancers. However, there is no study about the role of PLR in predicting response to first-line chemotherapy of metastatic gastric cancer. Therefore, this study aimed to establish whether PLR is associated with the response to first-line(More)
BACKGROUND The role of apolipoprotein (apo) E in kidney disease is still unclear. Animal studies have been performed, but it is doubtful if the conclusions are applicable to human beings. The objective of this study was to determine how apo E acts on human kidneys using primary cultured normal human mesangial cells (NHMCs) rather than animals used in(More)
Multiple drug resistance (MDR) and metastasis are two major factors that contribute to the failure of cancer treatment. However, the relationship between MDR and metastasis has not been characterized. Additionally, the role of the E3 ubiquitin ligase Cbl-b in metastasis of MDR gastric and breast cancer is not well known. In the present study, we found that(More)
Trastuzumab has been widely applied as a treatment for human epidermal growth factor 2 (HER2)-overexpressing breast cancer. However, the therapeutic efficacy of trastuzumab is limited. Flap endonuclease 1 (FEN1) is a multifunctional endonuclease that has a crucial role in DNA recombination and repair. Inhibition of FEN1 is associated with the reversal of(More)
