Therapeutic Effects of Natural Products on Liver Cancer and Their Potential Mechanisms

Liver cancer ranks third globally among causes of cancer-related deaths, posing a significant public health challenge. However, current treatments are inadequate, prompting a growing demand for novel, safe, and effective therapies. Natural products (NPs) have emerged as promising candidates in drug development due to their diverse biological activities, low toxicity, and minimal side effects. This paper begins by reviewing existing treatment methods and drugs for liver cancer. It then summarizes the therapeutic effects of NPs sourced from various origins on liver cancer. Finally, we analyze the potential mechanisms of NPs in treating liver cancer, including inhibition of angiogenesis, migration, and invasion; regulation of the cell cycle; induction of apoptosis, autophagy, pyroptosis, and ferroptosis; influence on tumor metabolism; immune regulation; regulation of intestinal function; and regulation of key signaling pathways. This systematic review aims to provide a comprehensive overview of NPs research in liver cancer treatment, offering a foundation for further development and application in pharmaceuticals and functional foods.

2,4'-Dihydroxybenzophenone Exerts Bone Formation and Antiosteoporotic Activity by Stimulating the β-Catenin Signaling Pathway

2,4'-Dihydroxybenzophenone (DHP) is an organic compound derived from Garcinia xanthochymus, but there have been no reports on its biochemical functions and bioavailability. In this study, we evaluated whether DHP affects osteoblast differentiation and activation in MC3T3-E1 preosteoblast cells, as well as antiosteoporotic activity in zebrafish larvae. Nontoxic concentrations of DHP-treated MC3T3-E1 preosteoblast cells increased alkaline phosphatase (ALP) activation and mineralization in a concentration-dependent manner, accompanied by higher expression of osteoblast-specific markers, including Runt-related transcription factor 2 (RUNX2), osterix, and ALP. Consistent with the data in MC3T3-E1 preosteoblast cells, DHP upregulated osteoblast-specific marker genes in zebrafish larvae and simultaneously enhanced vertebral formation. We also revealed that DHP increased the phosphorylation of glycogen synthase kinase-3β (GSK-3β) at Ser9 and the total expression of β-catenin in the cytosol and markedly increased the localization of β-catenin into the nucleus. Furthermore, DHP restored the prednisolone (PDS)-induced marked decrease in ALP activity and mineralization, as well as osteoblast-specific marker expression. In PDS-treated zebrafish, DHP also alleviated PDS-induced osteoporosis by restoring vertebral formation and osteoblast-related gene expression. Taken together, these results suggest that DHP is a potential osteoanabolic candidate for treating osteoporosis by stimulating osteoblast differentiation.

An Overview of Traditional Chinese Medicine in the Treatment After Radical Resection of Hepatocellular Carcinoma

According to the Barcelona Clinic Liver Cancer (BCLC) system, radical resection of early stage primary hepatocellular carcinoma (HCC) mainly includes liver transplantation, surgical resection, and radiofrequency ablation (RFA), which yield 5-year survival rates of about 70-79%, 41.3-69.5%, and 40-70%, respectively. The tumor-free 5-year rate for HCC patients undergoing radical resection only reach up to 13.7 months, so the prevention of recurrence after radical resection of HCC is very important for the prognosis of patients. The traditional Chinese medicine (TCM) takes the approach of multitarget and overall-regulation to treat tumors, it can also independently present the "component-target-pathway" related to a particular disease, and its systematic and holistic characteristics can provide a personalized therapy based on symptoms of the patient by treating the patient as a whole. TCM as postoperative adjuvant therapy after radical resection of HCC in Barcelona Clinic liver cancer A or B stages, and the numerous clinical trials confirmed that the efficacy of TCM in the field of HCC has a significant effect, not only improving the prognosis and quality of life but also enhancing patient survival rate. However, with the characteristics of multi-target, multi-component, and multi-pathway, the specific mechanism of Chinese medicine in the treatment of diseases is still unclear. Because of the positive pharmacological activities of TCM in combating anti-tumors, the mechanism studies of TCM have demonstrated beneficial effects on the regulation of immune function, chronic inflammation, the proliferation and metastasis of liver cancer cells, autophagy, and cell signaling pathways related to liver cancer. Therefore, this article reviews the mechanism of traditional Chinese medicine in reducing the recurrence rate of HCC after radical resection.

A Water-Soluble Polysaccharide from the Fibrous Root of Anemarrhena asphodeloides Bge. and Its Immune Enhancement Effect in Vivo and in Vitro

Background

The fibrous roots of Anemarrhena asphodeloides Bge. (FRAAB) are byproducts of the rhizome of Anemarrhena asphodeloides. Some studies have revealed secondary metabolic small molecules in FRAAB, but there are few reports on the polysaccharides of FRAAB (PFRAAB). Aim of the Study. The present study aimed to investigate the preliminary characterization and underlying mechanism of immune stimulation of PFRAAB.

Materials and Methods

The crude polysaccharide of FRAAB was obtained by hot water extraction and alcohol precipitation, and PFRAAB was purified by a diethylaminoethyl-52 (DEAE-52) cellulose chromatographic column and graphene dialysis membrane. The preliminary characterization of PFRAAB was studied by ultraviolet (UV) scanning and Fourier Transform Infrared Reflection (FTIR). The molecular weight and composition of PFRAAB were analysed by high-performance gel permeation chromatography (HPGPC) and high-performance liquid chromatography (HPLC), respectively. The immune stimulation of PFRAAB was investigated by using cyclophosphamide- (CCP-) treated mice and RAW264.7 cells.

Results

A water-soluble PFRAAB was obtained with a molecular weight of 115 kDa and was mainly composed of arabinose (ara), galactose (gal), glucose (glc), and mannose (man). Compared with CCP-induced mice, PFRAAB significantly (p < 0.05 or p < 0.01) increased the spleen and thymus index, ameliorated injury to the spleen and thymus, and evaluated immunoglobulin levels. In addition, PFRAAB also increased the secretion of nitric oxide (NO), interleukin-1β (IL-1β), tumour necrosis factor-α (TNF-α), and IL-6 in RAW264.7 cells and upregulated the expression of toll-like receptor 4 (TLR4), Myd88, nuclear factor kappa-B (NF-κB) P65, p–NF–κB P65, IKB-α, and p-IKB-α.

Conclusion

PFRAAB possesses immune stimulation activity and can be used as a potential resource for immune-enhancing drugs. Our present study provides a scientific basis for the comprehensive development of Anemarrhena asphodeloides medicinal plant resources.

Mechanism of Phellodendron and Anemarrhena Drug Pair on the Treatment of Liver Cancer Based on Network Pharmacology and Bioinformatics

Background

This study aims to explore the key targets and signaling pathways of the traditional Chinese medicine Phellodendron and Anemarrhena drug pair (PADP) for the treatment of liver cancer.

Methods

Firstly, bioinformatics technology was used to analyze GSE62232 gene chip to obtain the differential genes of liver cancer. A network pharmacology technology was used to find the active components of PADP and their targets. Secondly, the differential genes were imported into STRING database to draw a PPI network, and network topology structure map combined with Cytoscape software. And the R language was used to identify differential gene targets and pathways through GO and KEGG pathway enrichment analysis. In addition, AutoDock Vina was used for molecular docking of core targets and core compounds. Moreover, GEPIA online analysis tool was used to perform survival analysis of the core target genes. Finally, RT-PCR was used to verify the changes of key target genes. CCK−8 assay was performed to detect cell proliferation. Flow cytometry was performed to detect the cell cycle and apoptotic. Transwell invasion assay was performed to detect cell invasion.

Results

Firstly, a total of 21,654 genes were obtained. After screening, 1019 differential genes were obtained, including 614 down-regulated genes and 405 up-regulated genes. Furthermore, after screening by ADME standards, 52 active ingredients were obtained, of which 37 were Phellodendron and 15 were Anemarrhena. And a total of 36 differential genes have been identified, including 13 up-regulated genes and 23 down-regulated genes. Moreover, through enrichment analysis, we found that PADP may treat liver cancer through multiple channels and multiple pathways including the p53 signaling pathway, IL-17 signaling pathway, TNF signaling pathway, Toll-like receptor signaling pathway and so on. Secondly, the molecular docking results showed that there was certain affinity between the core compounds and core target genes. In addition, GEPIA online analysis showed that ESR1, AR, CCNB1, CDK1, AKR1C3 and CCNA2 might become potential target genes for the survival and prognosis of PADP for the treatment of liver cancer. Finally, it was found that PADP could up regulate genes ESR1 and AR, down regulate genes CCNB1, CDK1, AKR1C3, and CCNA2. PADP could promote the apoptosis of liver cancer cells, shorten the cell cycle, and inhibit the proliferation and invasion of liver cancer cells.

Conclusion

PADP may treat liver cancer through multiple targets, multiple channels, and multiple pathways, thereby suppressing cancer cells and improving the living quality of patients.

Timosaponin alleviates oxidative stress in rats with high fat diet-induced obesity via activating Nrf2/HO-1 and inhibiting the NF-κB pathway

Anemarrhena asphodeloides originated from the rhizome of Liliaceae Anemarrhena asphodeloides. One of the active pharmacological components of Anemarrhena asphodeloides is timosaponin (TSA), which reduces blood lipids and shows antioxidation and anti-inflammatory effects, but its mechanism is unclear. The objective of this study was to investigate the effect of TSA on oxidative stress induced by a long-term high-fat diet in obese rats. Body weight and the obesity index of the rats were measured during the experiment. Total antioxidant capacity (T-AOC), malondialdehyde (MDA), and glutathione peroxidase (GSH-Px) were used to detect oxidative stress indexes in serum and liver tissue. To observe the effect of TSA on the liver and adipose tissue of rats with oxidative stress, hematoxylin & eosin (H&E) staining was used. The p-NF-κB, NAD(P)H: quinone oxidoreductase 1 (NQO-1), Heme oxygenase 1 (HO-1), and Nrf2 in Nrf2/HO-1 and NF-κB pathways were assayed by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot. TSA was found to improve oxidative stress in obese rats by reducing MDA levels and increasing T-AOC and GSH-Px levels. Histological examination revealed that TSA effectively attenuated liver damage and improved obesity in rats. TSA was found to down-regulate the protein level of p-NF-κB and up-regulate the protein level of Nrf2/HO-1. These results suggested that TSA could effectively block inflammation and dyslipidemia in obese rats, thus improving oxidative stress, and its mechanism could be related to the Nrf2/HO-1 and NF-κB pathways.

2α-Hydroxyeudesma-4,11(13)-Dien-8β,12-Olide Isolated from Inula britannica Induces Apoptosis in Diffuse Large B-cell Lymphoma Cells

2α-Hydroxyeudesma-4,11(13)-dien-8β,12-olide (HEDO), a eudesmane-type sesquiterpene lactone belonging to large group of plant terpenoids isolated from Inula britannica, displays cytotoxic activity against diffuse large B cell lymphoma cells in vitro. However, the molecular mechanism of the anticancer effect remains unclear. In this study, we showed that HEDO inhibits cell growth by inducing apoptosis in lymphoma cell lines through its antiproliferative activity. HEDO increases the depolarization of mitochondrial membrane potential and upregulated intracellular reactive oxygen species (ROS). Furthermore, we examined the cell cycle effect, and our results provided evidence that the arrest of the cell cycle at the SubG0/G1 phase plays an important role in the ability of HEDO to inhibit cell growth in Ontario Cancer Institute (OCI)-LY3 lymphoma cells by preventing nuclear factor-kappa B (NF-κB) signaling. In addition, HEDO induced apoptosis by instigating the activation of Bcl-2-associated X (BAX) and cleaved caspase-3, decreasing B-cell lymphoma 2 (BCL2), B-cell lymphoma-extra large (BCL-XL), and procaspase 3 expression levels. Based on these findings, we suggest that HEDO has potential as an anticancer drug of lymphoma by inducing ROS-dependent accumulation of SubG0/G1 arrest and apoptosis in OCI-LY3 cells.
