BACKGROUND Hepatocellular carcinoma (HCC) remains a disastrous disease and the treatment for HCC is rather limited. Separation and identification of active compounds from traditionally used herbs in HCC treatment may shed light on novel therapeutic drugs for HCC. METHODS Cell viability and colony forming assay were conducted to determine anti-HCC(More)
Background. Hepatocellular carcinoma (HCC) represents the sixth common cancer in the world. Single nucleotide polymorphisms (SNPs) in microRNA genes may be associated with susceptibility to HCC. Recently, several studies have reported possible associations of SNPs miR-499 T>C rs3746444 and miR-34b/c T>C rs4938723 with the risk of HCC. However the results(More)
PURPOSE Tumor microenvironment confers drug resistance to kinase inhibitors by increasing RKT ligand levels that result in the activation of cell-survival signaling including PI3K and MAPK signals. We assessed whether HSC-LX2 coculture conferred sorafenib resistance in Huh7 and revealed the mechanism underlying the drug resistance. EXPERIMENTAL DESIGN The(More)
Background. Despite improvement in treatment, the prognosis of hepatocellular carcinoma (HCC) remains disastrous. Cancer stem cells (CSCs) may be responsible for cancer malignant behaviors. ATP-binding cassette, subfamily G, member 2 (ABCG2) is widely expressed in both normal and cancer stem cells and may play an important role in cancer malignant(More)
The Sonic Hedgehog (Shh) pathway affects cancer initiation, progression, and metastasis, but its role in papillary thyroid carcinoma (PTC) remains elusive. To characterize expression and clinical significance of Shh and the transcription factor Gli-1—the key elements of the Shh pathway in PTC tissues—we immunohistochemically examined Shh/Gli-1 expression in(More)
Human manganese superoxide dismutase (hMnSOD) is a new type of cancer suppressor. Nonamer of arginine (R9) is an efficient protein transduction domain (PTD). The aim of the study was to improve the transduction efficiency of hMnSOD and investigate its activity in vitro. In this study, we designed, constructed, expressed, and purified a novel fusion protein(More)
BACKGROUND Very little is known regarding correlation of micro RNA (miR)-106a with clinical outcomes of patients with glioblastoma multiforme (GBM). This study determined whether miR-106a could be used as an independent prognostic biomarker in those patients. METHODS A total of 156 GBM patients were divided into 2 cohorts. In the first cohort, matched(More)
AIM Rosin, the traditional Chinese medicine, is reported to be able to inhibit skin cancer cell lines. In this report, we investigate the inhibitory effect against HCC cells of QC2, the derivative of rosin's main components dehydroabietic acid. METHODS MTT assay was used to determine the cytotoxicity of QC2. Morphological changes were observed by(More)
Mdivi-1 is a selective inhibitor of mitochondrial fission protein, Drp1, and can penetrate the blood–brain barrier. Previous studies have shown that Mdivi-1 improves neurological outcomes after ischemia, seizures and trauma but it remains unclear whether Mdivi-1 can attenuate early brain injury after subarachnoid hemorrhage (SAH). We thus investigated the(More)
To investigate the effects of ethylene, in the form of ethephon (2-chloroethylphosphonic acid), on mycelial growth and ganoderic acid (GA) accumulation in the higher basidiomycete Ganoderma lucidum. Treatment with both 10 and 15 mM ethephon enhanced the growth of G. lucidum on solid CYM plates and in CYM liquid medium. After optimization using response(More)
