We studied the apoptosis-inducing properties of the antimicrobial peptide cecropin of Musca domestica in human hepatocellular carcinoma cell line BEL-7402 and its underlying mechanism. Proliferation inhibition of the human hepatocellular carcinoma BEL-7402 cells and the human normal liver cells were determined by the MTT assay, and the cell viability was(More)
Although studies have shown that heme oxygenase-1 (HO-1) can abrogate leukocyte recruitment and tissue injury after LPS stimulation, the underlying mechanisms remain incompletely understood. Interleukin (IL)-33, a new member of the IL-1 family, is found to play a crucial immunoregulatory effect on the MD2/TLR4 complex expression. Moreover, TLR4 further(More)
Although studies have demonstrated that heme oxygenase-1 (HO-1) prevents leukocyte infiltration and organ damage following LPS challenge, the mechanisms involved in this protection are incompletely understood. Macrophage migration inhibitory factor (MIF) is thought to play a pivotal role in modulation of inflammatory and immune response through upregulation(More)
Although Wedelia chinensis, an herb in traditional Chinese medicine, has been widely used for the treatment of inflammation, the effects of W. chinensis on cancer cell growth and the related molecular mechanisms behind these effects have largely remained unexplored to date. In the present study, W. chinensis plant extracts were obtained using either ethanol(More)
This work studied the transcriptional patterns of three antibacterial genes, attacin, defensin and cecropin, during the development of Musca domestica. Quantitative analysis by real-time PCR was performed on mRNA levels in different development stages and challenged 3rd-instar larva at different time points after challenge of Musca domestica. The results(More)
BACKGROUND In our previous study, a novel liver-targeting fusion interferon (IFN-CSP) combining IFN α2b with plasmodium region I peptide was successfully constructed. IFN-CSP has significant inhibition effects on HBV-DNA replication in HepG2.2.15 cells. The aim of the present investigation was focused on how to produce high levels of recombinant IFN-CSP and(More)
ClC-3, a gene encoding a candidate protein for volume-activated chloride (C(-)) channels, may be involved in tumor development. Herein we report a study using an antisense "knock-down" strategy to investigate the mechanism by which ClC-3 affects cell proliferation in nasopharyngeal carcinoma CNE-2Z cells. With immunoblots and MTT assays we demonstrated that(More)
Stretch-activated chloride currents (I(Cl,SA) ) have been considered to be a component of volume-activated chloride currents (I(Cl,vol) ) for some time. This is due to a similarity in biophysical and pharmacological properties that involve a membrane curvature-induced mechanism and rearrangement of the cytoskeleton induced by cell swelling or membrane(More)
Tamoxifen is a triphenylethylene non-steroidal antiestrogen anticancer agent. It also shows inhibitory effects on metastasis of estrogen receptor (EsR)-independent tumors, but the underlying mechanism is unclear. It was demonstrated in this study that, in EsR-negative and highly metastatic human hepatocellular carcinoma MHCC97H cells, tamoxifen-inhibited(More)
Various tumor cells express interleukin 7 (IL-7) and IL-7 variants. IL-7 has been confirmed to stimulate solid tumor cell proliferation. However, the effect of IL-7 variants on tumor cell proliferation remains unclear. In this study, we evaluated the role of IL-7δ5 (an IL-7 variant lacking exon 5) on proliferation and cell cycle progression of human(More)
