OBJECTIVETo investigate the effects of nitrogen forms on the camptothecin (CPT) content, tryptophan synthase (TSB) and tryptophan decarboxylase (TDC) activities in Camptotheca acuminata seedlings.

METHODThe seedlings of C. acuminata with 6 pairs of leaves were subjected to 5 different NH4(+) -N/NO3(-) -N ratio (0 : 100, 75 : 25, 50 : 50, 25 : 75, 100 : 0) treatments by sand culture in a greenhouse. The CPT content, TSB activity in the young leaves and TDC in the stem barks of the seedlings were determined by HPLC on the 15th, 30th, 45th, 60th and 75th day, respectively.

RESULTThe obvious relationship between CPT content and nitrogen forms was observed. When NH4(+) - N /NO3(-) -N ratio was 25 : 75, CPT accumulation in young leaves displayed the best advantages (the highest value is 5.69 per thousand) and increased in the early 30 days of treatment and then declined. There was no obvious relationship between TSB activity in the young leaves and nitrogen forms. TDC activity in the stem bark was the highest when NH4(+) -N /NO3(-) -N ratio was 25 : 75, and the change of TDC activity paralleled to CPT content in the young leaves.

CONCLUSIONA short-term treatment that NH4(+) -N /NO3(-) -N ratio was 25:75 may gain high CPT content in the young leaves through enhancing the TDC activity in the stem bark of C. acuminata seedlings.

Objective To investigate the drug resistance of side population cells in human gallbladder cancer cell line GBC-SD and explore its mechanism. Methods Drug sensitivity assays of 5chemotherapeutic agents were performed on side population cells (SP) and non-SP cells of GBC-SD.GBC-SD was cultured and then treated with the chemotherapeutic agent gemcitabine. The frequency of SP by FACS was measured. RT-PCR and Western blotting were used to detect the expression of AB-CG2 in both the SP and the corresponding non-SP subsets. Results After 1 d treatment with 4 chemotherapeutic agents (gemcitabine, cisplatin, 5-fluorouracil and mitoxantrone) in IC50 concentration to GBC-SD cell line, the reproductive ability of SP was higher than that of non-SP (P<0.05). However, statistical significance was not achieved when compared with epirubicin (P>0.05). The percentage of SP in GBC-SD treated with chemotherapeutic agent gemcitabine after 3 weeks was sharply elevated by FACS (8.02% ±0.13% vs 0.62% ±0.08%, P<0.05), and the expression of ABCG2mRNA and protein were increased in SP as compared with non-SP. Conclusion SP from human gallbladder cancer cell line GBC-SD, like stem cell, showed a heighten resistance to drugs. Increased expression of ABCG2 was largely responsible for the multi-drug resistance.

ObjectiveTo explore the tumor igenic property of side population cells (SP) from human gallbladder carcinoma cell line GBC-SD. Methods SP and non-SP cells were isolated from GBC-SD staining with Hoechst33342 dye by fluorescence-activated cell sorting (FACS). The soft agar clonal assay and xenograft assay were performed to characterize tumorigenic property of side population cells in vitro and in vivo, respectively. The percentage of SP cells was analyzed by FACS in 5 hu man gallbladder carcinoma specimens. ResultsThe percentage of SP cells accounted for approximately 0.87 ％ of GBC-SD cells. The clone-formed rates of SP was more frequent than that of non-SP cells (14.74％ ± 3.53％ vs 5.17％ ± 1.05％), there was statistically significant difference (t =2.75,P＜0. 05). SP cells could generate tumors with as few as 5 × 103 cells (four of seven animals), whereas at least 1 × 105 non-SP cells were needed to form a tumor (one of seven animals). Re-analysis of SPderived tumors by FACS showed that SP cells under in vivo conditions also have the capacity to regenerate the SP and non-SP fractions. Besides, analysis of Hoechst33342 revealed s small fraction of SP cells, ranging from 0. 27％ to 2.3％ in gallbladder carcinoma specimens. ConclusionSP cells from GBC-SD are highly tumorigenic similar as the cancer stem cells.
