Description
An account of the resource
Due to the existence of cancer stem cells (CSCs), persistence and relapse of human hepatocellular carcinoma (HCC) are common after treatment with existing anti-cancer therapies. Emerging evidence indicates that lipopolysaccharide (LPS) plays a crucial role in aggravating HCC, but information about the effect of LPS on CSCs of HCC remains scant. Here, we report that the stemness of CD133(+) CSCs sorted from the human HCC cell line Huh7 was maintained well when cells were cultured with LPS. The reduction of CD133 expression was much lesser in cultured CSCs in the presence of LPS. In response to LPS stimulation, CSCs showed an increase in their activity of clonogenesis and tumorigenesis. LPS also supported maintaining CSC abilities of migration, invasion, and chemo-resistance. Treatment with HIF-1alpha-specific siRNA significantly reduced CD133 expression by CSCs at both mRNA and protein levels. Further, the expression of HIF-1alpha and CD133 was reduced in LPS-stimulated CSCs when the NF-kappaB inhibitor was added to the cell culture. HIF-1alpha-specific siRNA also effectively counteracted the effect of LPS on maintaining CSC abilities of migration and invasion. These data indicate that LPS, an important mediator in the liver tumor microenvironment, supports the maintenance of CSC stemness through signaling of the NF-kappaB/HIF-1alpha pathway. Our current study highlights LPS as a potential target for developing new therapeutic approaches to eliminate CSCs during the treatment of HCC.

Description
An account of the resource
Pomegranate fruit extract (PE) rich in polyphenols has been shown to exert chondroprotective effects, but the mechanism is not established. Here, we used an in vitro model of inflammation in osteoarthritis (OA) to investigate the potential of PE to suppress interleukin 1 beta (IL-1beta)-stimulated expression of inflammatory cytokine IL-6, generation of reactive oxygen species (ROS) levels, and investigated the mechanism of NF-kappaB inhibition by analyzing the activation of the kinases upstream of IkappaBalpha in primary human chondrocytes. Total and phosphorylated forms of kinases and expression of IL-6 were determined at protein and mRNA levels by western immunoblotting and Taqman assay, respectively. Dihydrorhodamine 123 staining estimated ROS generation. Pomegranate fruit extract inhibited the mRNA and protein expression of IL-6, generation of ROS, and inhibited the IL-1beta-mediated phosphorylation of inhibitor of nuclear factor kappa-B kinase subunit beta (IKKbeta), expression of IKKbeta mRNA, degradation of IkappaBalpha, and activation and nuclear translocation of
