Abstract Legumain is a C13 family cysteine protease. It plays diverse roles under both physiological and pathological conditions. The high-level expression of legumain is detected in solid tumors. Legumain promotes the proliferation and migration of tumor cells. However, the effect of legumain in blood diseases has not been established. In this report, we studied the effect of legumain on leukemia cells by overexpressing it in THP1 cells. The results demonstrated that legumain promoted cell proliferation, whereas it had little effect on cell apoptosis. Furthermore, legumain promoted the migration of THP1 cells. It was worth noting that More >

Abstract Cancer cell stemness is responsible for cancer relapse, distal metastasis, and drug resistance. Here we identified that Frizzled 2 (Fzd2), one member of Wnt receptor Frizzled family, induced human breast cancer (BC) cell stemness via noncanonical Wnt pathways. Fzd2 was overexpressed in human BC tissues, and Fzd2 overexpression was associated with an unfavorable outcome. Fzd2 knockdown (KD) disturbed the mesenchymallike phenotype, migration, and invasion of BC cells. Moreover, Fzd2 KD impaired BC cell mammosphere formation, reduced Lgr5+ BC cell subpopulation, and enhanced sensitivity of BC cells to chemical agents. Mechanistically, Fzd2 modulated and bound with More >

Abstract The aim of this study was to identify a novel cancer stemness-related ceRNA regulatory axis in lung adenocarcinoma (LUAD) via weighted gene coexpression network analysis of a stemness index. The RNA sequencing expression profiles of 513 cancer samples and 60 normal samples were obtained from the TCGA database. Differentially expressed mRNAs (DEmRNAs), lncRNAs (DElncRNAs), and miRNAs (DEmiRNAs) were identified with R software. Functional enrichment analysis was conducted using DAVID 6.8. The ceRNA network was constructed via multiple bioinformatics analyses, and the correlations between possible ceRNAs and prognosis were analyzed using Kaplan–Meier plots. WGCNA was then… More >

Abstract Recently, novel therapeutic strategies have been designed with the aim of killing cancer stem-like cells (CSCs), and considerable interest has been generated in the development of specific therapies that target stemnessrelated marker of CSCs. In this study, nonsteroidal anti-inflammatory drugs (NSAIDs) significantly potentiated Hsp90 inhibitor 17-allylamino-17-demethoxygeldanamycin (17-AAG)-mediated cytotoxicity through apoptotic and autophagic cell death induction, but COX-2-inhibitory function was not required for NSAIDinduced autophagy in CD44-overexpressing human chronic myeloid leukemia K562 (CD44^highK562) cells. Importantly, we found that treatment with NSAIDs resulted in a dose-dependent increase in LC3-II level and decrease in p62 level and simultaneous reduction… More >

Abstract Hepatocellular carcinoma (HCC) is the third most common cancer in the world. Previous studies have shown that hard matrix promotes the proliferation of liver tumor cells. However, the role of matrix stiffness on hepatic cancer stem cells (HCSCs) is still unclear. Three-dimensional hydrogels with different stiffness were used to mimic the normal liver tissue (4kPa) and cancerous liver tissue (26kPa) stiffness. The proliferation, stemness and invasion properties of HCSCs under 3D different stiffness were detected. METHOD: HSCSs were screened and cultured by enrichment method, and the effect of matrix stiffness on HCSCs was studied by… More >

Abstract Gliomas are the most common primary brain tumors. The most malignant form, the glioblastoma multiforme (GBM; WHO IV), is characterized by an invasive phenotype, which enables the tumor cells to infiltrate into adjacent brain tissue. When investigating GBM migration and invasion properties in vitro, in most cases GBM cell lines were analyzed. Comprehensive investigations focusing on progression-dependent characteristics of migration processes using fresh human glioma samples of different malignancy grades do not exist. Thus, we isolated fast-migrating tumor cells from fresh human glioma samples of different malignancy grades (astrocytomas WHO grade II, grade III, GBM,… More >
