Applications

Synergistic inhibitory effect of berberine and d-limonene on human gastric carcinoma cell line MGC803.[Pubmed: 25045784]J Med Food. 2014 Sep;17(9):955-62. This study aims at evaluating the anticancer effects of Berberine hydrochloride (Berberine) and d-limonene, alone and in combination, on human gastric carcinoma cell line MGC803 to determine whether Berberine and d-limonene work synergistically and elucidate their mechanisms. MGC803 cells were treated with Berberine and d-limonene, alone and in combination, for 24-48 h. METHODS AND RESULTS: The inhibitory effects of these drugs on growth were determined by MTT assay. The combination index and drug reduction index were calculated with the Chou-Talalay method based on the median-effect principle. Flow cytometry and laser scanning confocal microscopy were employed to evaluate the effects of both drugs on cell-cycle perturbation and apoptosis, generation of reactive oxygen species (ROS), mitochondrial membrane potential, and expression of Bcl-2 and caspase-3 in MGC803 cells. Berberine or d-limonene alone can inhibit the growth of MGC803 cells in a dose- and time-dependent manner. Berberine and d-limonene at a combination ratio of 1:4 exhibited a synergistic effect on anti-MGC803 cells. The two drugs distinctly induced intracellular ROS generation, reduced the mitochondrial transmembrane potential (ΔΨm), enhanced the expression of caspase-3, and decreased the expression of Bcl-2. The combination of Berberine and d-limonene showed more remarkable effects compared with drugs used singly in MGC803 cells. CONCLUSIONS: The combination of Berberine and d-limonene exerted synergistic anticancer effects on MGC803 cells by cell-cycle arrest, ROS production, and apoptosis induction through the mitochondria-mediated intrinsic pathway.

Abstract

Objective: To study the safety of topical berberine solution in rabbit eyes and its effect on corneal epithelial repair in rabbit eyes. Methods: Experimental Study. Ninety-two Japanese rabbits were randomly divided into two groups by random number table method: the general group (32 rabbits, 64 eyes) and the corneal injury group (60 rabbits, 60 eyes).The general groups were further divided into 4 groups by random number table method, and each group has 8 rabbits (16 eyes). According to the administration of deionized water or 0.5, 1.0, 1.5 mg/ml berberine solution, they were divided into the general control group and the general A, B, and C group. Dosing with both eyes, each eye was given a single dose, and then it was given multiple times for 4 weeks after observation for 72h. After the corneal epithelium injury model made in the right eye of rabbits in the corneal injury groups, they were divided into a corneal injury control group and a corneal injury group A, B, and C according to the administration of deionized water or 0.5, 1.0, 1.5 mg/ml berberine solution. there were 5 rabbits (15 eyes) in each group, and the solutions were given continuously for 1 week. The rabbits in the general group were observed their behavioral changes, ocular surface and iris were scored by Draize eye irritation test scoring system. IOP was measured at different time points. Electroretinogram (ERG) was used to detect b-wave amplitude. In the corneal injury group, corneal epithelial defect repairment was observed at 1, 2, 3, 4, 5, 6, and 7 days after the corneal defect. Corneal histopathology observation after discontinuation of all rabbits. The pH value of rabbit tears was described by the paired t test, and the score of Draize eye irritation test were described by the rank-sum test. The analysis of variance and SNK-q were used for IOP, electroretinogram b-wave amplitude, corneal epithelial injury area and repair time. Results: No abnormal behavior was observed in the general group rabbits after single and multiple administration. There was no significant difference in the Draize eye irritation score among the general control group and the general group A, B, C at 1, 2, and 4 weeks of multiple administrations. Among them, the Draize eye irritation score of the general group C was 7 (0, 12), 6 (0, 10), 6 (0, 16) points (χ(2)=1.640, 0.265, 1.963, 1.381; P>0.05).There were no significant difference in IOP at different times among the general control group and the general group A, B, C at different times (F=0.065, 0.292, 0.015, 0.041; P>0.05). Before multiple administrations and after administration at 2, 4 weeks, the b-wave amplitudes of the general control group were (127.75±17.12), (129.18±15.83), (128.81±13.58) μV, and the general group A were (130.68).±18.75), (131.38±16.96), (130.62±12.18) μV,and the general group B were (128.00±16.74), (128.44±16.64), (129.06±16.16) μV, and the general group C were (131.81±19.37), (132.13±18.36), (129.94±12.60) μV. There was no statistically significant difference in b-wave amplitude in the groups at different times before and after administration (F=0.037, 0.011, 0.017, 0.702; P>0.05). There was no significant difference in the results of corneal histopathology among the general control group and the general group A, B, C. The area of corneal epithelial defect in each corneal injury group was statistically significant at different time (F=5.316, 25.864, 127.613; P<0.05). The corneal injury control group compared with the corneal injury group A, B, C, the corneal epithelial defect area in the corneal injury group C was significantly larger than the other three groups, with statistical differences (q=5.153, 10.313, 6.976; P<0.05). The repair time of corneal epithelial in control group and the group A,B,C of corneal injury were (83.0±1.85), (82.9±2.07), (83.7±2.09) and (101.6±2.20) h. The corneal epithelium defect repair time in group C was longer and the difference was statistically significant (F=301.437, P=0.000). Comparing the corneal injury control group and corneal injury group A and B, there was no statistical difference in the repair time of corneal epithelial defect (F=0.813, P=0.450). After repair, there was no significant difference in the pathological results of the corneal tissue between the corneal injury groups. Conclusions: Berberine solution in rabbit eyes with topical application was safety, and has no obvious toxic effect on the ocular surface and ERG of normal rabbits. 1.5 mg/ml berberine solution delayed the repair of experimental corneal epithelial defect, but had no effect on the integrity of corneal tissue after repair.

Abstract

AIM:
Emerging studies have shown that application of low concentration of bioactive phytomolecules can confer anti-proliferative effects on tumour cells by inducing senescence pathways. The alkaloid berberine is recognized for its anti-cancer attributes but its potential to induce senescence in tumour cells is least understood.

MATERIALS AND METHODS:
The present work assessed the mechanisms pertaining to dose-dependent anti-proliferative effects of berberine in the perspective of senescence and inflammation using human non-small cell lung cancer cell line (A549).

KEY FINDINGS:
Amongst the different tested bioactive phytomolecules, berberine treatment suppressed the proliferation of A549 cells regardless of the concentration applied. Application of low doses of berberine induced a weak SA-β-gal activity and p21WAF1 expression but did not show evidence of SASP activation due to absence of NF-κB activation and expression of proinflammatory genes. However, treatment with higher dose of berberine showed no evidence of SA-β-gal activity or p21WAF1 expression, but instead induced apoptosis and suppressed the expression of cell cyclins. The proliferative capacity of berberine treated cells was at par with control cells and no SA-β-gal activity could be observed in first generation of berberine treated cells. mTOR pathway showed no distinct activation on account of berberine treatment thereby further emphasizing that low dose of berberine induced quiescence and not senescence in A549 cells.

SIGNIFICANCE:
Taken together, our observations indicate that despite its strong anti-proliferative effects, low dose berberine treatment may only induce transient changes akin to quiescence that needs to be considered before implying pro-senescence attributes of berberine in cancer therapeutics.

Abstract

AIMS:
Berberine (BBR) is reported to induce apoptosis and inhibit migration of leukemic cells, but the underlying pharmacological mechanisms have not been fully revealed. This study aims to investigate the possible mechanisms from the perspective of autophagy.

MAIN METHODS:
P-53-null leukemic cell lines Jurkat and U937 were used for the in vitro study. MDC staining was used for observation of autophagy in leukemic cells, and Western blot analysis was for determination of the expression levels of autophagy-associated proteins. Apoptosis of the leukemic cells was detected by flow cytometry. Cellular location of MDM2 was observed with immunofluorescence staining. Ubiquitination of MDM2 was assessed by immunoprecipitation. Male 6-8-week-old NOD/SCID mice were used for evaluating the effect of BBR on chemotherapy sensitivity in vivo.

KEY FINDINGS:
BBR induced autophagy in p53-null leukemic cells, which was inhibited by autophagy inhibitors 3-methyladenine. 3-methyladenine also inhibited BBR-induced apoptosis in leukemic cells. In addition, BBR not only decreased MDM2 mRNA expression, but also enhanced MDM2 self-ubiquitination in leukemic cells. Forced overexpression of MDM2 reversed the effect of BBR on autophagy and apoptosis. Furthermore, BBR promoted doxorubicin-induced autophagy and cell death in the leukemic cells and overexpression of MDM2 suppressed these effects. In vivo, BBR combined with doxorubicin achieved better therapeutic effect than doxorubicin alone.

SIGNIFICANCE:
MDM2 inhibits autophagy and apoptosis in leukemic cells in a p53-independent manner. BBR induces autophagy in p53-null leukemic cells through downregulating MDM2 expression at both transcriptional and post-transcriptional levels, which may contribute to the anti-cancer effect of BBR in leukemia.
