OBJECTIVETo label a human bladder cancer cell line and establish a novel human bladder cancer mouse model.

METHODST-24 cells, a human bladder transitional cell carcinoma cell line, were transfected with GFP plasmid to screen stable GFP-expressing clones. The latter were implanted into the wall of the bladder or the subcutaneous tissue of the neck of nude mice. The growth, invasion, and metastasis of the implanted tumor were observed and evaluated with whole-body optical imaging system. The findings were compared with those of HE staining on routine paraffin sections.

RESULTSGFP-labeled tumor cells displayed green fluorescence under fluorescent microscopy and showed stable GFP expression in vitro and in vivo. One week after in situ transplantation of 5 x 10(5) T24 cells, the new bladder cancer was observed and evaluated under whole-body optical imaging system. Two weeks later, the new bladder tumor could be palpated, and 4 weeks later, metastasis to regional drainage lymph nodes in the pelvic and retroperitoneal lymph nodes occurred. The growth and metastasis of the implant bladder tumor were easily observed and accurately evaluated by fluorescent microscope.

CONCLUSIONGFP-labeled tumor cells display green fluorescence under fluorescent microscopy and show stable GFP expression. GFP-labeled T-24 cells and the novel human bladder cancer model described hereby provide a simple and reliable means for studying human bladder cancer in vivo.

OBJECTIVETo investigate the effects of Hic-5/ARA55 on the growth of the human colorectal cancer cells (Lovo cells) and its mechanism.

METHODFlow cytometry (FCM) was used to study the cell cycle of Lovo cells (Lovo group), Lovo cells stably transfected with empty vector (Lovo-Vector group) and the Lovo cells stably transfected with vector containing Hic-5/ARA55 (Lovo-Hic-5/ARA55 group). Western blot assay was used to detect the principal cyclins in the three groups, and Luciferase assay was used to study the mechanism between Hic-5/ARA55 and the only target cyclin. The cells from the three groups were inoculated subcutaneously into 7 nude mice (Balb/c nu/nu) respectively to observe the effects of Hic-5/ARA55 on the growth of the cells in vivo. Seven weeks later, the subcutaneous tumors were harvested and weighed. Then immunohistochemistry assay was used to detect Hic-5/ARA55 and the target cyclin in the tumors.

RESULTSThe cell cycle was obviously delayed from G0/G1 to S stage in Lovo-Hic-5/ARA55 cells. A significantly higher expression of P27 was found in Lovo-Hic-5/ARA55 cells than in the other two groups. The weight of the subcutaneous tumors of Lovo-Hic-5/ARA55 cells, Lovo cells and Lovo-Vector cells were (0.33 +/- 0.23) g, (1.20 +/- 0.39) g and (1.30 +/- 0.49) g, respectively; the tumors of Lovo-Hic-5/ARA55 cells was significantly lighter than those of the other two groups (P<0.05). Hic-5/ARA55 and P27 were both over-expressed in implanted tumors of Lovo-Hic-5/ARA55 cells, while were both expressed lower or not expressed in the other two groups. And the expressions of Hic-5/ARA55 and P27 were highly positive correlated (r=0.816, P<0.05).

CONCLUSIONHic-5/ARA55 could inhibit the growth of Lovo cells both in vitro and in vivo by up-regulating the transcription of P27.

OBJECTIVETo investigate the expression of proline-rich tyrosine kinase-2 (Pyk2) in human primary colorectal carcinoma (CRC) and it's prognostic significance.

METHODSThe expression of Pyk2 was retrospectively examined with immunohistochemistry (IHC) in 108 tissues of primary CRC. The correlation of Pyk2 expression to prognosis and relevant clinical factors were analyzed.

RESULTSThe rate of Pyk2 low-expression in CRC was 56.5% (61/108). The expression of Pyk2 correlated significantly to the histological grade (P < 0.05) and the TNM stage (P < 0.05), while no correlation between Pyk2 expression and age, tumor size (P > 0.05). Patients with Pyk2 over-expression had significantly higher 5-year survival rate (66.0%) than those with Pyk2 low-expression (31.4%). Pyk2 expression, together with carcinoma histologic grade and TNM stage were prognostic factors to CRC on the multivariate analysis.

CONCLUSIONSPyk2 expression can be a prognostic factor to the CRC patients together with other predictors.

OBJECTIVETo evaluate the prognostic value of lateral pelvic lymph node metastasis on low rectal cancer.

METHODSOne hundred and seventy-six patients with low rectal cancer who underwent radical resection combined with lateral pelvic lymph node dissection between 1994 and 2005 were reviewed. The data of the cases was investigated to define the prognostic value of lateral pelvic lymph node metastasis on the patients.

RESULTSLateral node metastasis occurred in 33 patients (18.8%), and 51.5% of the metastasis occurred in internal iliac nodes or nodes at middle rectal roots and 39.4% in obturator nodes. Age < or =40 years, infiltrative cancer, T34 tumor, upward lymph node metastasis were risk factors for lateral node metastasis in low rectal cancer (P < 0.05). The overall 5-year survival rate was 64.1%, and it was 94.1%, 79.1%, 42.1% for patients with TNM stage I, II, III cancer, respectively. Tumor size, depth of infiltration, upward lymph node metastasis, lateral node metastasis was correlated significantly with prognosis (P < 0.05). The 5-year survival rate of the patients without lateral metastasis was 73.6%, which was significant higher than that of patients with lateral metastasis (21.4%, P < 0.05).

CONCLUSIONLateral pelvic lymph node metastasis is an important prognostic factor for low rectal cancer.

OBJECTIVETo explore the effect of transforming growth factor alpha (TGFalpha) on the expression of cyclin E and D1 in gastric carcinoma cells.

METHODSHuman gastric adenocarcinoma SGC7901 cells were cultured routinely and synchronized at G(0)/G(1) phase in serum-free RPMI-1640. The percentage of the cells at G(0)/G(1) phase was detected by propidium iodide staining and flow cytometry (FCM), and the synchronized cells were cultured in RPMI-1640 supplemented with 2.5% calf serum and treated with 10, 30, and 50 microg/L TGFalpha for 5 h. The expression of cyclin E and D1 in SGC7901 cells was detected by immunofluorescent staining and FCM.

RESULTSThe percentage of the cells at G(0)/G(1) phase increased from 54% in routine culture to 72% in the serum-free RPMI-1640 culture. TGFalpha treatment of the cells synchronized at G(0)/G(1) phase induced significant increment of cyclin E and D1 expressions (P<0.001), and at the dose of TGFalpha of 50 microg/L, their expressions increased by 25.18% and 27.52%, respectively (P<0.001).

CONCLUSIONTGFalpha can increase the expression of cyclin E and D1 in gastric carcinoma cells to promote their cell cycle progress.
