A mixture of Pueraria lobata and Platycodon grandiflorum extracts ameliorates RANKL-induced osteoclast differentiation and ovariectomy-induced bone loss by regulating Src- PI3K-AKT and JNK/p38 signaling pathways. Heliyon 2024; 10:e24842. [PMID: 38312605 PMCID: PMC10835310 DOI: 10.1016/j.heliyon.2024.e24842] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 01/15/2024] [Accepted: 01/15/2024] [Indexed: 02/06/2024] Open
Abstract
Osteoporosis is caused by increased bone resorption due to the excessive activity of osteoclasts. Pueraria lobata has demonstrated the ability to improve bone density in ovariectomized mice, and Platycodon grandiflorum can suppress osteolysis biomarkers such as collagen content in cartilage and alkaline phosphatase activity. In this study, we examined whether HX112, a mixture of Pueraria lobata and Platycodon grandiflorum extracts, could inhibit the receptor activator of nuclear factor-κB (NF-κB) ligand (RANKL)-induced osteoclast differentiation to alleviate osteoporosis. To induce the differentiation of osteoclasts, RAW 264.7 cell were cultured with RANKL and HX112. Osteoclasts differentiation was evaluated by TRAP activity and TRAP staining. Bone resorption as osteoclasts major function was assessed by pit formation assay. As a result, HX112 suppressed osteoclast differentiation and bone resorptive function. Additionally, HX112 reduced the expression of osteoclastogenic genes including NFATc1 and c-Fos, and these effects of HX112 were mediated by inhibiting Src-phosphoinositide 3-kinase (PI3K)- Protein kinase B (Akt) and c-Jun N-terminal kinase (JNK)/p38 signaling pathways. Furthermore, ICR mice were ovariectomized to induce osteoporosis and bone mineral density of femur was measured using micro-CT. Consequently, oral administration of HX112 to ovariectomized mice significantly improved bone microstructure and bone mineral density. Collectively, these findings indicate that the mixed extract of Pueraria lobata and Platycodon grandiflorum may be useful as therapeutics for osteoporosis.

Exp Hematol 2023:S0301-472X(23)00160-1. [PMID: 37085039 DOI: 10.1016/j.exphem.2023.04.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 04/10/2023] [Accepted: 04/13/2023] [Indexed: 04/23/2023]
Abstract
Patients with diffuse large B-cell lymphoma (DLBCL) have unsatisfactory outcomes especially when relapse occurs after initial chemotherapy. Platycodin D (PD), a triterpenoid saponin isolated from the root of Platycodon grandiflorum (Jacq.) A. DC., has demonstrated potent anti-cancer activities. So far, however, information regarding the effect of PD on malignant lymphoma remains unavailable. In the present study, we showed that PD dose-dependently inhibited the viability of a serial of established DLBCL cell lines representing different molecular subtypes, and their sensitivities to PD were comparable. Mitochondrial dysfunction and subsequent intrinsic apoptosis were induced by PD, as indicated by the loss of mitochondrial membrane potential and the increase in the percentage of Annexin Ⅴ positive cells. Mechanistically, PD treatment downregulated expression levels of anti-apoptotic proteins including MCL-1, BCL-2, and BCL-XL, while upregulated the expression level of pro-apoptotic protein BAK, followed by the cleavage of PARP. Moreover, PD synergistically enhanced the cytotoxicity of BCL-2 inhibitor venetoclax. In a SUDHL-4-derived xenograft mouse model, PD administration significantly constrained the tumor growth without obvious side effects. Therefore, our results provided new insights into the role of PD in lymphoma therapy.

Abstract
Endometrial cancer (EC) is a complex disease that affects the reproductive health of females worldwide. Platycodin D (PD) is known to exert numerous anticancer effects, markedly inhibiting cell proliferation, inducing apoptosis and causing cell cycle arrest in several types of cancer. The present study aimed to explore the mechanisms underlying the effects of PD in EC cells. The viability and proliferation of human endometrial stromal cells (ESCs) and RL95-2 EC cells following treatment with PD were evaluated using Cell Counting Kit-8, MTT and colony formation assays. Wound healing and Transwell assays were also performed to assess the migration and invasion of EC cells following treatment with PD. The expression levels of α2A-adrenergic receptor (ADRA2A) were measured using reverse transcription-quantitative PCR and western blotting assays with and without PD treatment and following transfection with short hairpin (sh) RNAs targeting ADRA2A2. Moreover, western blot analysis was performed to measure the expression levels of Ki67, PCNA, MMP2 and MMP9 and the phosphorylation of proteins of the PI3K/Akt signaling pathway. The results demonstrated that treatment with PD markedly decreased the proliferation, invasion and migration of EC cells, and reduced activation of the PI3K/Akt signaling pathway in EC cells. Moreover, transfection with sh-ADRA2A attenuated the effects of PD. ADRA2A expression was downregulated in EC cells compared with ESCs, and ADRA2A expression was elevated in EC cells following treatment with PD. In conclusion, the present study indicates that PD blocked the PI3K/Akt signaling pathway via the upregulation of ADRA2A expression, thereby inhibiting the proliferation, invasion and migration of EC cells.

Abstract
BACKGROUND The traditional Chinese medicine Platycodon grandiflorum (Jacq.) A. DC. (PG, balloon flower) has medicinal and culinary value. It consists of a variety of chemical components including triterpenoid saponins, polysaccharides, flavonoids, polyphenols, polyethylene glycols, volatile oils and mineral components, which have medicinal and edible value. PURPOSE The ultimate goal of this review is to summarize the phytochemistry, pharmacological activities, safety and uses of PG in local and traditional medicine. METHODS A comprehensive search of published literature up to March 2022 was conducted using the PubMed, China Knowledge Network and Web of Science databases to identify original research related to PG, its active ingredients and pharmacological activities. RESULTS Triterpene saponins are the primary bioactive compounds of PG. To date, 76 triterpene saponin compounds have been isolated and identified from PG. In addition, there are other biological components, such as flavonoids, polyacetylene and phenolic acids. These extracts possess antitussive, immunostimulatory, anti-inflammatory, antioxidant, antitumor, antiobesity, antidepressant, and cardiovascular system activities. The mechanisms of expression of these pharmacological effects include inhibition of the expression of proteins such as MDM and p53, inhibition of the activation of enzymes, such as AKT, the secretion of inflammatory factors, such as IFN-γ, TNF-α, IL-2 and IL-1β, and activation of the AMPK pathway. CONCLUSION This review summarizes the chemical composition, pharmacological activities, molecular mechanism, toxicity and uses of PG in local and traditional medicine over the last 12 years. PG contains a wide range of chemical components, among which triterpene saponins, especially platycoside D (PD), play a strong role in pharmacological activity, representing a natural phytomedicine with low toxicity that has applications in food, animal feed and cosmetics. Therefore, PG has value for exploitation and is an excellent choice for treating various diseases.

Abstract
Obesogens are defined as chemicals that trigger obesity partially by stimulating adipogenesis. Adipogenesis consists of two successive processes: the adipocyte lineage commitment of pluripotent stem cells and the differentiation of preadipocytes. Compared with the differentiation of preadipocytes, the effects of most environmental obesogens on adipocyte lineage commitment remain largely unknown. In this study, investigations are performed to explore the influences of PBDE 99 on the adipocyte lineage commitment based on C3H10T1/2, which has been widely used as a mesenchymal stem cell (MSC) model. Our results indicated that exposure to PBDE 99 during commitment stage resulted in significant up-regulation of subsequent adipogenesis in C3H10T1/2 MSCs. Interestingly, PBDE 99 did not affect the osteogenesis of C3H10T1/2 MSCs, although the adipogenesis and osteogenesis of MSCs are typically reciprocal. PBDE 99 was further demonstrated to significantly decrease the expression of Pref1, the marker of very early adipose mesenchymal precursor, and its downstream effector, Sox9. This result strongly suggested that PBDE 99 facilitated adipocyte commitment to exert adipogenic effect on C3H10T1/2 MSCs. Mechanistic studies revealed that PBDE 99 efficiently inhibited Hedgehog signaling transduction, a conserved negative regulator of the adipocyte lineage commitment. Furthermore, the effects of PBDE 99 on adipogenesis were abrogated by the co-treatment with SAG, a specific Hedgehog signaling activator, suggesting inhibition of Hedgehog signaling is responsible for the effect of PBDE 99 on adipocyte commitment. Taking together, these results strongly suggested enhanced adipocyte lineage commitment was involved in potential obesogenic effect of PBDE 99, presumably through repressing Hedgehog signalling during commitment stage. Moreover, the results of this study indicated that C3H10T1/2 can be used as a feasible MSCs cell model to evaluate the capabilities of potential obesogens on adipocyte commitment.

Abstract
Diabetic nephropathy (DN) is associated with inflammation. Platycodin D (PD) demonstrates anti-inflammatory activity. However, whether PD affects DN remains to be explored. Here, we aimed to discuss the role of PD in DN and its underlying mechanisms. High glucose (HG)-induced HK-2 cells were treated with PD, and cell viability was assessed using the Thiazolyl Blue Tetrazolium Bromide (MTT) assay. Ferroptosis-related factors such as lactate dehydrogenase (LDH) activity, lipid reactive oxygen species (ROS), iron (Fe2+) level, GSH level, and malondialdehyde (MDA) level were evaluated. Cell death was evaluated using the TUNEL assay. GPX4 expression was evaluated using Quantitative Real-time PCR (qRT-PCR) and Western blotting analysis. The results indicated that HG increased LDH activity, lipid ROS production, Fe2+ levels, and MDA levels and decreased GSH levels, suggesting that the HG condition induced ferroptosis. PD treatment inhibited ferroptosis in HG-induced cells, downregulated ACSL4 and TFR1 expression, and upregulated FTH-1 and SLC7A11 expression. PD reversed the effects of HG condition on cell death. Moreover, GPX4 expression was downregulated in HG-stimulated cells. Furthermore, we substantiated that PD suppressed ferroptosis by modulating GPX4 expression. In conclusion, PD inhibited ferroptosis in HG-induced HK-2 cells by upregulating GPX4 expression, suggesting that PD may be an effective drug for the clinical treatment of DN.

Abstract
Platycodonis Radix (Jiegeng), the dried root of Platycodon grandiflorum, is a traditional herb used as both medicine and food. Its clinical application for the treatment of cough, phlegm, sore throat, pulmonary and respiratory diseases has been thousands of years in China. Platycodin D is the main active ingredient in Platycodonis Radix, which belongs to the family of pentacyclic triterpenoid saponins because it contains an oleanolane type aglycone linked with double sugar chains. Modern pharmacology has demonstrated that Platycodin D displays various biological activities, such as analgesics, expectoration and cough suppression, promoting weight loss, anti-tumor and immune regulation, suggesting that Platycodin D has the potential to be a drug candidate and an interesting target as a natural product for clinical research. In this review, the distribution and biotransformation, pharmacological effects, metabolic mechanism and safety evaluation of Platycodin D are summarized to lay the foundation for further studies.
