小檗碱水合物（天然黄色18氯化物水合物；1.25-160 μM；72小时）可能对四种结直肠癌细胞系LoVo、HCT116、SW480和HT-29的生长有抑制作用[1]。小檗碱氯化物水合物（1.25-160 μM；24-72 小时）可促进 LoVo 细胞增殖的时间和剂量依赖性抑制 [1]。 LoVo 细胞用氯化小檗碱水合物 (10-80 μM) 处理 24 小时。通过流式细胞术对 40 μM 小檗碱处理的 LoVo 细胞进行细胞周期研究，结果显示细胞积累在 G2/M 期 [1]。小檗碱氯化物水合物 (10-80 μM) 在 24 小时后抑制细胞周期蛋白 B1、cdc2 和 cdc25c 蛋白表达，尤其是在 80.0 μM 剂量时 [1]。

人结直肠腺癌的体内生长受到氯化小檗碱水合物（天然黄色18氯化物水合物；10、30或50mg/kg/天；胃肠道灌胃；连续10天）的抑制。在裸鼠中，每天 30 毫克/公斤和 50 毫克/公斤的水合小檗碱可分别抑制人结直肠癌异种移植物 33.1% 和 45.3% [1]。

蛋白质印迹和OPTDI分析用于检测细胞周期蛋白[1]

In vivo anti-tumor effect of berberine in human colorectal adenocarcinoma (LoVo)[1]
The in vivo antitumor efficacy of berberine was examined using human colorectal adenocarcinoma LoVo xenografts in a nude mouse model; 1 × 107 cells were implanted subcutaneous injection (s.c.) in the flanks of 5-week-old BALB/c nu/nu mice. After the tumors were grown up to about 1,000–1,500 mm3, the mice were sacrificed and the tumors were divided into equal fragments. Fragments (6–8 mm3) of colorectal adenocarcinoma were implanted s.c. in the flanks of 5-week-old BALB/c nu/nu mice. Tumors were allowed to develop for 2 weeks. Once tumors were established, the mice were divided randomly into five groups. The berberine-treated groups (ten mice each group) received 10, 30, or 50 mg kg−1 day−1 berberine by gastrointestinal gavage for 10 consecutive days. The 5-FU-treated group (10 mice) was given 30 mg kg−1 day−1 by intraperitoneal injection for 10 consecutive days. The control group (11 mice) was given sterile water. Measurements of body weights and tumor volumes were recorded every 1–3 days until the experimental endpoint, at which the tumors were debilitating to the mice. The long axis (L) and the short axis (S) were measured, and the tumor volume (V) was calculated using the following equation: V = S × S × L/2. Once the final measurement was taken, the mice were sacrificed by cervical dislocation. The inhibitory rates were determined by comparing the volume of the control group and the treatment group: (1 − V treatment/Vcontrol).

Effect of the combination of berberine and 5-FU on the growth of human colorectal adenocarcinoma (HT-29) xenografts in nude mice[1]
The in vivo antitumor efficacy of the combination of berberine and 5-FU was examined using human colorectal adenocarcinoma HT-29 xenografts in a nude mouse model; 1 × 107 cells were implanted subcutaneous injection (s.c.) in the flanks of 5-week-old BALB/c nu/nu mice. After the tumors were grown up to about 1,000–1,500 mm3, the mice were sacrificed and the tumors were divided into equal fragments. Fragments (6–8 mm3) of colorectal adenocarcinoma were implanted s.c. in the flanks of 5-week-old BALB/c nu/nu mice. Tumors were allowed to develop for 3 weeks. Once tumors were established, the mice were divided randomly into four groups. The berberine-treated group (ten mice) received 50 mg kg−1 day−1 berberine by gastrointestinal gavage for 10 consecutive days. The 5-FU-treated group (10 mice) was given 30 mg kg−1 day−1 by intraperitoneal injection for 10 consecutive days. The combination group (10 mice) was given berberine and 5-FU. The control group (10 mice) was given sterile water. Measurements of body weights and tumor volumes were recorded every 3–4 days until the experimental endpoint, at which the tumors were debilitating to the mice. The long axis (L) and the short axis (S) were measured, and the tumor volume (V) was calculated using the following equation: V = S × S × L/2. Once the final measurement was taken, the mice were sacrificed by cervical dislocation. The inhibitory rates were determined by comparing the volume of the control group and the treatment group: (1 − V treatment/V control).
