Effects of Dipotassium glycyrrhizinate on wound healing
Acta Cir Bras 2021 Oct 8;36(8):e360801.PMID:34644769DOI:10.1590/ACB360801.
Purpose: Dipotassium glycyrrhizinate (DPG) has anti-inflammatory properties, besides promoting the regeneration of skeletal muscle. However, it has not been reported on skin wound healing/regeneration. This research aimed to characterize the effects of DPG in the treatment of excisional wounds by second intention. Methods: Male adults (n=10) and elderly (n=10) Wistar rats were used. Two circular wounds were excised on the dorsal skin. The excised normal skins were considered adult (GAN) and elderly (GIN) naïve. For seven days, 2% DPG was applied on the proximal excision: treated adult (GADPG) and elderly (GIDPG), whereas distal excisions were untreated adult (GANT) and elderly (GINT). Wound healing areas were daily measured and removed for morphological analyses after the 14th and the 21st postoperative day. Slides were stained with hematoxylin-eosin, Masson's trichrome, and picrosirius red. Results: Histological analysis revealed intact (GAN/GIN) and regenerated(GANT/GINT/GADPG/GIDPG) skins. No differences of wounds' size were found among treated groups. Epidermis was thicker after 14 days and thinner after 21 days of DPG administration. Higher collagen I density was found in GIDPG (14th day) and GADPG (21st day). Conclusions: DPG induced woundhealing/skin regeneration, with collagen I, being more effective in the first 14 days after injury.
Dipotassium glycyrrhizinate relieves leptospira-induced nephritis in vitro and in vivo
Microb Pathog 2021 Mar;152:104770.PMID:33545326DOI:10.1016/j.micpath.2021.104770.
Chronic leptospirosis usually occurs during sublethal doses infection of susceptible animal and reservoir host, which typical symptom is interstitial nephritis, and leptospira urine, contaminating the environment and threatening other susceptible animals and humans. Dipotassium glycyrrhizinate (DG) is a replacement for glycyrrhizic acid, which exhibits anti-inflammation, immunomodulation effects. This study is to investigate whether DG relieves leptospira-induced nephritis. In vitro, DG inhibited the leptospira-induced transcription levels of IL-1β, IL-6, TNF-α, RANTES, MCP-1 and iNOS, and protein levels of IL-1β and TNF-α, and downregulated NF-κB and MAPK pathway in TCMK-1 cells. In vivo, DG attenuated the kidney histopathological change and downregulated the expression of IL-1β and TNF-α, as well as reduced kidney leptospiral burden. In summary, DG alleviated leptospira-induced inflammation through inhibitory NF-κB and MAPK pathway, and DG decreased the renal colonization of leptospires in mice.
Anti-histamine effects of Dipotassium glycyrrhizinate on lung fibroblasts, implicating its therapeutic mechanism for pulmonary fibrosis
J Pharm Pharmacol 2022 Sep 1;74(9):1241-1250.PMID:35788858DOI:10.1093/jpp/rgac030.
Objectives: To examine the possible anti-histamine effects of Dipotassium glycyrrhizinate (DG), a dipotassium salt of glycyrrhizic acid, on histamine-mediated lung fibroblast activation, differentiation and proliferation; to investigate the potential and underlying mechanisms for pulmonary fibrosis (PF) treatment. Methods: Rat primary lung fibroblasts were extracted to establish cell models; histamine, DG and loratadine (LTD, a histamine receptor antagonist) were applied. Cell proliferation, migration and cell cycle were explored; intracellular signal proteins were detected; mitochondrial membrane potential was examined. Key findings: The anti-histamine effects of DG were found in a similar pattern of LTD on lung fibroblasts. DG inhibited histamine-induced cell activation, proliferation and migration; DG altered histamine-mediated mitochondrial membrane potentials. DG reduced the histamine-induced PAR-2 (a tryptase receptor) expression to impair mast cell tryptase co-working. Histamine-induced expressions of MMP-2, FAK, TNF-α, P38, iNOS were decreased by DG, while Bax and caspase-3, P53 were increased by DG against histamine effects. Histamine drove cells from G0/G1 to S phases, whereas DG rested cells by inhibiting G0/G1 and G2/M phases. Conclusions: This study provided the evidences that DG can inhibit histamine-induced effects on lung fibroblasts and promote apoptosis of abnormally activated lung fibroblasts, implicating its potential therapeutic mechanisms against PF development, also for those histamine-related diseases.
Dipotassium glycyrrhizinate on Melanoma Cell Line: Inhibition of Cerebral Metastases Formation by Targeting NF-kB Genes-Mediating MicroRNA-4443 and MicroRNA-3620-Dipotassium Glycyrrhizinate Effect on Melanoma
Int J Mol Sci 2022 Jun 29;23(13):7251.PMID:35806253DOI:10.3390/ijms23137251.
Glycyrrhizic acid (GA), a natural compound isolated from licorice (Glycyrrhiza glabra), has exhibited anti-inflammatory and anti-tumor effects in vitro. Dipotassium glycyrrhizinate (DPG), a dipotassium salt of GA, also has shown an anti-tumor effect on glioblastoma cell lines, U87MG and T98G. The study investigated the DPG effects in the melanoma cell line (SK-MEL-28). MTT assay demonstrated that the viability of the cells was significantly decreased in a time- and dose-dependent manner after DPG (IC50 = 36 mM; 24 h). DNA fragmentation suggested that DPG (IC50) induced cellular apoptosis, which was confirmed by a significant number of TUNEL-positive cells (p-value = 0.048) and by PARP-1 [0.55 vs. 1.02 arbitrary units (AUs), p-value = 0.001], BAX (1.91 vs. 1.05 AUs, p-value = 0.09), and BCL-2 (0.51 vs. 1.07 AUs, p-value = 0.0018) mRNA compared to control cells. The proliferation and wound-healing assays showed an anti-proliferative effect on DPG-IC50-treated cells, also indicating an inhibitory effect on cell migration (p-values < 0.001). Moreover, it was observed that DPG promoted a 100% reduction in melanospheres formation (p-value = 0.008). Our previous microRNAs (miRs) global analysis has revealed that DPG might increase miR-4443 and miR-3620 expression levels. Thus, qPCR showed that after DPG treatment, SK-MEL-28 cells presented significantly high miR-4443 (1.77 vs. 1.04 AUs, p-value = 0.02) and miR-3620 (2.30 vs. 1.00 AUs, p-value = 0.01) expression compared to control cells, which are predicted to target the NF-kB, CD209 and TNC genes, respectively. Both genes are responsible for cell attachment and migration, and qPCR revealed significantly decreased CD209 (1.01 vs. 0.54 AUs, p-value = 0.018) and TNC (1.00 vs. 0.31 AUs, p-value = 2.38 × 10−6) mRNA expression levels after DPG compared to untreated cells. Furthermore, the migration of SK-MEL-28 cells stimulated by 12-O-tetradecanoylphorbol-13-acetate (TPA) was attenuated by adding DPG by wound-healing assay (48 h: p-value = 0.004; 72 h: p-value = 7.0 × 10−4). In addition, the MMP-9 expression level was inhibited by DPG in melanoma cells stimulated by TPA and compared to TPA-treated cells (3.56 vs. 0.99 AUs, p-value = 0.0016) after 24 h of treatment. Our results suggested that DPG has an apoptotic, anti-proliferative, and anti-migratory effect on SK-MEL-28 cells. DPG was also able to inhibit cancer stem-like cells that may cause cerebral tumor formation.
Ameliorating effect of Dipotassium glycyrrhizinate on an IL-4- and IL-13-induced atopic dermatitis-like skin-equivalent model
Arch Dermatol Res 2019 Mar;311(2):131-140.PMID:30506356DOI:10.1007/s00403-018-1883-z.
Atopic dermatitis (AD) is a chronic inflammatory skin disease that is not fully understood. Defects in skin barrier function and dysregulation of the Th2 immune response are thought to be pivotal in AD pathogenesis. In this study, we used keratinocytes and AD-like skin equivalent models using Th2 cytokines IL-4 and IL-13. The keratinocytes and AD-like skin model were used to investigate the effect of Dipotassium glycyrrhizinate (KG), which is widely used as an anti-inflammatory agent for AD treatment. KG decreased AD-related gene expression in keratinocytes stimulated with Th2 cytokines. KG alleviated AD-like phenotypes and gene expression patterns and inhibited release of AD-related cytokines in the AD-like skin equivalent models. These findings indicate KG has potential effectiveness in AD treatment and AD-like skin equivalent models may be useful for understanding AD pathogenesis.
