There is a possibility that berberine sulfate (1.25-160 μM; 72 hours) will decrease the growth of four colorectal cancer cell lines: LoVo, HCT116, SW480, and HT-29[1]. Berberine Sulfate (10 - 80 μM) was used for 24 hours to generate LoVo cells (1.25-160 μM; 24-72). Using flow cytometry, experiments were conducted on LoVo cells treated with 40 μM berberine. After a 24-hour period, berberine sulfate (10-80 μM) suppresses the expression of cyclin B1, cdc2, and cdc25c proteins, particularly at a level of 80.0 μM[1]. Cycle analysis also reveals a build-up of cells in the G2/M phase.

For ten straight days, gastrointestinal gavage treated with berberine sulfate (10, 30, or 50 mg/kg/day) suppresses colorectal cancer growth in vivo. (30 and 50 mg/kg/d); perfusion in the gastrointestinal tract

Western blotting and OPTDI analysis for detecting cell cycle proteins[1]
LoVo cells were harvested, lysed in lysis buffer [50 mmol/L TrisCl (pH 6.8), 100 mmol/L DTT, 2 % SDS, 0.1 % bromophenol blue, 10 % glycerin] at 100 °C for 10 min and stored at −20 °C. Protein concentrations were determined by BCA assay. Equal protein amounts were loaded onto SDS-polyacrylamide gels, and the proteins were transferred electrophoretically to a PVDF membrane. Immunoblots were analyzed using specific primary antibodies to cyclin B1, cdc2 and cdc25c (1:200 dilution) and incubated with horseradish peroxidase-conjugated secondary antibodies (1:1,000 dilution), and the proteins were visualized using an enhanced chemiluminescence detection kit. The optical density integral (OPTDI) was analyzed by an automatic image analysis system. The expression of cyclin B1, cdc2 and cdc25c was normalized to internal controls (GAPDH). The results were presented as percentages of treatments compared to the control.

Measurement of DNA and protein synthesis[1]
DNA and protein synthesis was assessed by the cellular incorporation of 3H-thymidine and L-[4,5-3H]-leucine (60 Ci/mg molecular and 0.5 μCi/well respectively). Isolated cells (1 × 105 cells per well) were incubated with medium containing a series of concentrations of berberine. Four hours before the 24-h berberine exposure, radioactive precursors were added to the culture. At the end of the incubation period, the medium was removed to a piece of filter membrane; the cells were washed three times with distilled water. 3H-thymidine and L-[4,5-3H]-leucine incorporation was determined by liquid scintillation spectrometry.

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).
