Overexpression of miR-30a-5p enhanced the effects of curcumol on cell invasion and migration, and the Hippo signaling pathway in CRC cells. Furthermore, downregulation of miR-30a-5p reversed the effects of curcumol on cell invasion and migration, and the Hippo signaling pathway in CRC cells. These findings identified novel signaling pathways associated with miR-30a-5p and revealed the effects of curcumol on miR-30a-5p expression. Therefore, curcumol may serve as a potential therapeutic strategy to delay CRC progression.Pancreatic cancer (PC) is a malignant tumour of the human digestive system that has a poor prognosis. Exosomes contain proteins and nucleic acids, and constitute a class of extracellular vesicles defined as membrane-bound nanovesicles of endocytic origin, with a diameter of 40-150 nm. Exosomes are potential diagnostic markers of PC; however, their roles in cancer initiation and progression remain unclear. Previous studies have focused on the molecular mechanisms and functions of exosomes that allow them to accelerate PC cell proliferation, migration and invasion. The present review discusses the interactions between exosomes and the pathophysiology of PC. The potential clinical applications of exosomes are also discussed.Lung adenocarcinoma (LUAD) is the most common subtype of lung cancer. Nevertheless, the detailed molecular mechanisms of the progression of LUAD remain largely unknown. The present bioinformatics analysis reported that FAM83A and FAM83A-AS1 were upregulated in LUAD tissues and associated with prognosis in patients with LUAD. The purpose of the current study was to investigate the role of FAM83A and its antisense long non-coding (lnc)RNA FAM83A-AS1 in LUAD. Gene Expression Profiling Interactive Analysis was used to screen for potential oncogenes in LUAD and to analyze the clinical significance of FAM83A and FAM83A-AS1. Small interfering RNAs were constructed and transfected into LUAD cells to knock down the expression of FAM83A and FAM83A-AS1. EdU, Cell Counting Kit-8, Transwell and Matrigel assays were performed to detect the proliferation, migration and invasion of LUAD cells. The interaction between FAM83A-AS1, microRNA (miR)-495-3p and FAM83A was explored using a luciferase reporter assay. FAM83A and FAM83A-AS1 were both overexpressed in LUAD tissues compared with adjacent normal tissues. High expression of FAM83A and FAM83A-AS1 predicted worse survival and more advanced clinical stage. Knockdown of FAM83A or FAM83A-AS1 could inhibit the proliferation, migration and invasion of LUAD cells. Moreover, lncRNA FAM83A-AS1 regulated the expression of FAM83A by functioning as competing endogenous RNA for miR-495-3p. These results implicated that FAM83A and FAM83A-AS1 both played oncogenic roles in LUAD and FAM83A-AS1 could regulate the expression of FAM83A by sponging miR-495-3p. The study revealed a novel regulatory mechanism of tumor development in LUAD and FAM83A and FAM83A-AS1 may be novel biomarkers and therapeutic targets for LUAD.Gastric cancer (GC) is one of the most common types of cancer worldwide. Previous studies have reported that phosphofructo-2-kinase/fructose-2,6-biphosphatase 4 (PFKFB4) functions as an oncoprotein in various types of cancer. However, the association between PFKFB4 and GC remains unclear. The present study analyzed the expression levels of PFKFB4 in 148 GC tissue samples, including 46 tumor tissues with matched adjacent normal tissues, using immunohistochemistry, compared the expression levels of PFKFB4 between GC and adjacent normal tissues, and determined the association between PFKFB4 expression levels and patient clinicopathological characteristics. In addition, survival curves were generated using the Kaplan-Meier (KM) plotter database to evaluate the association between PFKFB4 expression and GC prognosis. NF-κΒ activator 1 nmr The results revealed that PFKFB4 expression was upregulated in GC tissues compared with in adjacent normal tissues. PFKFB4 expression was associated with patient age, tumor size, pathological tumor (pT) stage and tumor-node-metastasis (pTNM) stage, and upregulated expression levels of PFKFB4 were observed in tumor tissues from patients less then 65 years old (compared with that in patients ≥65 years old), as well as patients with a larger tumor size and an advanced stage (pT and pTNM stage) disease. In addition, KM survival analysis demonstrated that patients with low PFKFB4 expression had a significantly improved overall survival (OS), first progression survival and post-progression survival times compared with those with high PFKFB4 expression. Furthermore, PFKFB4 expression was negatively associated with OS time in patients with late pT and pTNM stage disease. In conclusion, the results of the present study indicated that the upregulated PFKFB4 expression in GC tissues may serve as a biomarker for a more advanced disease and a poor prognosis in patients with GC.Tumor necrosis factor related apoptosis inducing ligand (TRAIL) is a promising anti-myeloma drug prototype. The aim of the present study was to investigate the synergistic effects of cyclopamine and circularly permuted TRAIL (CPT) on the proliferation and apoptosis of multiple myeloma cells. The results showed that the inhibitory effects of cyclopamine on the proliferation of human myeloma RPMI-8226 and SKO-007 cells were weak. RPMI-8226 cells were sensitive to CPT; however, the proliferation of SKO-007 cells was not effectively inhibited by CPT. SKO-007 cells were thus considered resistant to cyclopamine and CPT and used for subsequent experiments. Treatment with a combination of cyclopamine and CPT significantly inhibited cell proliferation. Moreover, the Q value showed that cyclopamine combined with CPT could synergistically inhibit the proliferation of SKO-007 cells. Cyclopamine increased CPT-induced apoptosis in the SKO-007 cells and exhibited a synergistic induction of apoptosis when combined with CPT. Moreover, the combination of cyclopamine and CPT decreased the ratio of myeloma stem cells. Quantitative PCR showed that cyclopamine decreased the mRNA expression levels of GLI1/GLI2/GLI3 and increased the expression levels of death receptor 4. In conclusion, the present study showed that a combination of cyclopamine and CPT exhibited synergistic effects on the inhibition of proliferation and induction of apoptosis in myeloma cells.
