OBJECTIVE Multidrug resistance (MDR) in human B-cell lymphoma constitutes a major obstacle to the effectiveness of chemotherapy. The aim of this study was to investigate the molecular mechanism of MDR in B-cell lymphoma. MATERIALS AND METHODS The B-cell lymphoma MDR sublines were developed by exposing the parental Daudi cells to stepwise increasing(More)
Due to accelerated energy consumption, enhanced function of mitochondria in tumour cells compared to normal cells is prerequisite for tumour development. Leucine-rich pentatricopeptide repeat motif-containing protein (LRPPRC) regulates the expression of all mitochondrial DNA-encoded mRNAs, thus plays an important role in the mitochondrial function. LRPPRC(More)
FGFR1, one of the four fibroblast growth factor receptors, has been found to be over-expressed in many cancers. In this study, a full-length expression plasmid for FGFR1 was obtained by fragment amplification. The amplified PCR product was then digested and inserted into the pcDNA3.1(+) vector. A recombinant eukaryotic expression vector containing the(More)
The present study was to demonstrate the effect of taspine isolated from Radix et Rhizoma Leonticis on tumor angiogenesis and its mechanism of action. The anti-angiogenic effect in vivo was evaluated on chicken chorioallantoic membrane (CAM) neovascularisation model and CAM transplantation tumor model. Taspine exerted inhibitory influence on CAM(More)
The aim of the present study was to investigate an anti-angiogenic effect of taspine isolated from Radix et Rhizoma Leonticsi. Taspine was screened for the first time, using cell membrane chromatography (CMC). The anti-angiogeneic activity of taspine was tested by using the chicken chorioallantoic membrane (CAM) neovascularisation model in vivo and the(More)
High activity of aldehyde dehydrogenase (ALDH) is characteristic of normal and cancerous stem cells. Recently, high ALDH expression was shown to be associated with poor prognosis in uterine endometrial adenocarcinoma. The population with high ALDH activity (ALDH-hi) was more invasive, anti-apoptotic, and tumorigenic than that with low activity (ALDH-lo).(More)
Tumor cells with tumorigenic potential might be limited to a small population of cells, called cancer-initiating cells (CICs). CICs efficiently form colonies in vitro, yield both CIC and non-CIC populations, maintain reactive oxygen species (ROS) at low levels, show high aldehyde dehydrogenase (ALDH) activity, and are mostly in a quiescent state of the cell(More)
Pre B cell leukemia homeobox 2 (PBX2), a member of PBX family, acts as a co-factor of homeobox proteins to regulate proliferation and differentiation of tumor cells. Our recent study revealed prognostic significance of PBX2 expression in non-small cell lung carcinoma. The significance of PBX2 expression was examined in cases with gastric cancer (GC) and(More)
Angiogenesis plays an important role in colon cancer development. This study aimed to demonstrate the effect of brucine on tumour angiogenesis and its mechanism of action. The anti-angiogenic effect was evaluated on the chicken chorioallantoic membrane (CAM) model and tube formation. The mechanism was demonstrated through detecting mRNA and protein(More)
Brucine is an alkaloid from nux vomica, has been shown various pharmacological actions. To study the possible anti-cancer mechanisms on LoVo cells, effects of Brucine on cell viability, cell cycle and apoptosis were investigated. The results showed that Brucine revealed strong growth inhibitory effect on LoVo cells, and caused LoVo cell shrinkage and(More)
