“…Notably, the roots of licorice (Glycyrrhiza) have been used to treat inflammation, gastric ulcers and atherosclerosis, in folk and traditional herbal medicine in Eastern Asian countries, including Korea, Japan and China (30,31). Licorice root contains alkaloids, polysaccharides, and flavonoids (32).…”

Abstract. The aim of the present study was to investigate licochalcone-E (Lico-E)-induced apoptosis and the associated apoptotic signaling pathway in FaDu cells, a human pharyngeal squamous carcinoma cell line. Treatment with Lico-E exhibited significant cytotoxicity on FaDu cells in a concentration-dependent manner. The IC 50 value of Lico-E in FaDu cells was ~50 µM. Treatment with Lico-E increased the number of dead FaDu cells. Furthermore, chromatin condensation, which is associated with apoptotic cell death, was observed in FaDu cells treated with Lico-E for 24 h. By contrast, Lico-E did not produce cytotoxicity or increase the number of dead cells when applied to human normal oral keratinocytes (hNOKs). Furthermore, chromatin condensation was not observed in hNOKs treated with Lico-E. Treatment with Lico-E increased the expression of Fas ligand and the cleaved form of caspase-8 in FaDu cells. Furthermore, treatment with Lico-E increased the expression of pro-apoptotic factors, including apoptosis regulator BAX, Bcl-2-associated agonist of cell death, apoptotic protease-activating factor 1, caspase-9 and tumor suppressor p53, while decreasing the expression of anti-apoptotic factors, including apoptosis regulator Bcl-2 and Bcl-2-like protein 1 in FaDu cells. The expression of cleaved caspases-3 and poly (ADP-ribose) polymerase was significantly upregulated following treatment with Lico-E in FaDu cells, while Lico-E-induced apoptotic FaDu cell death was partially suppressed by treatment with Z-VAD-FMK, a pan caspase inhibitor. Therefore, Lico-E-induced oral cancer (OC) cell-specific apoptosis is mediated by the death receptor-dependent extrinsic and mitochondrial-dependent intrinsic apoptotic signaling pathways. In conclusion, these data suggested that Lico-E exhibits potential chemopreventive effects and warrants further developed as a chemotherapeutic agent against OC.

“…Isoliquiritigenin, one of the bioactive components of licorice, is often used as an anti-inflammatory, antimicrobial, anti-diabetic, and anti-tussive agent [5, 8]. Moreover, isoliquiritigenin has been found to inhibit growth and aromatase activity of breast cancer cells and thus, has potential to be used as a chemotherapeutic agent in breast cancer [9–11].…”

Isoliquiritigenin is a botanical estrogen used as a dietary supplement. Previous studies show that other botanical estrogens affect ovarian estradiol synthesis, but isoliquiritigenin’s effects on the ovary are unknown. Thus, this study tested the hypothesis that isoliquiritigenin inhibits ovarian antral follicle growth and steroidogenesis. Antral follicles from CD-1 mice were cultured with vehicle control (dimethyl sulfoxide; DMSO) or isoliquiritigenin (0.6 μM, 6 μM, 36 μM, and 100 μM) for 48–96h. During culture, follicle diameters were measured daily to assess follicle growth. After culture, media were collected for hormone assays and follicles were collected for gene expression analysis of steroidogenic enzymes. Isoliquiritigenin inhibited antral follicle growth and altered estradiol, testosterone, and progesterone levels. Additionally, isoliquiritigenin altered the mRNA levels of cytochrome P450 steroid 17-α-hydroxylase 1, aromatase, 17β-hydroxysteroid dehydrogenase 1, and steroidogenic acute regulatory protein. These data indicate that exposure to isoliquiritigenin inhibits growth and disrupts steroid production in antral follicles.

“…There is a global attempt to design more powerful drugs for the treatment of lung cancer with low toxicity, but the results are unsatisfactory. Fortunately, emerging evidence has demonstrated that some herbal drugs, such as the active components of licorice, could be better choices to improve the current therapeutic strategy [2][3][4].…”

Background: Currently, there is a global attempt to identify potential anti-cancer agents with low toxicity. Previous studies have found that glycyrrhizin exerts anti-cancer action with low toxicity through suppressing thromboxane A2 (TxA2) in lung cancer cell lines. However, these effects have not yet been determined in animal models of lung cancer. Methods: Human lung adenocarcinoma xenografts were established in nude mice by the introduction of A549 cells with stable transfection of the TxA2 receptor (TPα). The animal model was confirmed by the hematoxylin and eosin (H&E) method. Tumor-bearing mice were then administered graded concentrations of glycyrrhizin, cisplatin or both. After the treatments, body weights of all animals were recorded, and immunohistochemistry staining of lung tissues and serum biochemistry detection of aspartate amino transferase (AST), alanine amino transferase (ALT), urea and creatinine were carried out. Results: Treatment with glycyrrhizin alone or the combination of cisplatin and glycyrrhizin profoundly reduced expression of thromboxane synthase (TxAS) as well as proliferating cell nuclear antigen (PCNA), recovered the body weight, and rescued damage of liver and kidney in tumor-bearing mice. Although it inhibited PCNA expression, cisplatin could not significantly suppress TxAS expression. Because of a positive feedback loop between TPα and TxAS, the effects of glycyrrhizin are possibly attributable to the suppression of the TxA2 pathway. Conclusions: This study provides in vivo evidence to support glycyrrhizin as a potential candidate for developing new regimens to overcome tumor progression and the resistance and toxicity of cisplatin.
