十全大补汤对荷膀胱癌小鼠大剂量化疗的减毒增效作用

Objective To investigate the toxicity attenuation and efficacy potentiation effects of Shiquan Dabu Tang (SDT) on high dose chemotherapy in T739 mice with bladder carcinoma. Methods Mouse bladder carcinoma tissue was inoculated subcutaneously into T739 mice to establish tumor-beating mice model. The tumor-bearing mice were randomly divided into a CTX group (100, 200, 400 mg/Kg respectively), a SDT group (high or low dose respectively), a high-dose SDT combined with 200 mg/Kg CTX group and a control group. The body weight, diameter of tumor nodules and complete blood count were observed subsequently. Results Different doses of SDT could effectively inhibit tumor growth in mice. SDT + CTX treatment significantly prolonged the survival time of mice by 49.4±23.3 days (P<0.01, 0.05, 0.01), compared with high dose SDT treatment (17.4±5.77) days, 200 mg/kg CTX treatment (23±14.02) days and control group (11.75±2.06) days respectively. The peripheral platelet count increased more significantly in mice treated with SDT within a week as compared to mice without SDT treatment (P<0.05). The peripheral RBC count and liB concentration increased more significantly in mice treated with SDT for 2 weeks as compared to mice without SDT treatment (P<0.05). Conclusions SDT could enhance the anti-tumor effects of high dose CTX on tumor-bearing mice and reduce toxicity in its peripheral red blood cells. The results showed that SDT combined with high dose of CTX chemotherapy had toxicity attenuation and efficacy potentiation effects in tumor-beating T739 mice.

Abstract：

Objective To investigate the possible effects of COL8A1 on the proliferation, invasion and drug sensitivity of murine hepatocarcinoma cell line Hca-F, we used an RNA interference (RNAi) approach to silence COL8A1 expression. Methods The expression levels of COL8A1 in HcaF/siRNA cells were assessed by RT-PCR and Western blot. The inhibitory effect of RNAi on Hca-F cell invasion in vitro was demonstrated by ECM invasion assay. The in vitro proliferative ability and drug sensitivity of COL8A1-deficient cells were determined by MTT assay. Results The expression of COL8A1 was significantly reduced in COL8A1/siRNA cells after 30h transfection, compared with both the RNAi control and the Hca-F cells. The reduced COL8A1 expression also attenuated the proliferative, invasive ability, as well as increased drug sensitivity of Hca-F/siRNA cells. Conclusion Our current results indicate that the expression of COL8A1 functionally mediates tumor cell proliferation, invasion, and drug sensitivity, and is a potential target for therapeutic anti-cancer drugs.
