Curcumae rhizoma and its major constituents against hepatobiliary disease: Pharmacotherapeutic properties and potential clinical applications

Curcumaones A-N, sesquiterpenes from the secondary rhizomes of Curcuma wenyujin

Fourteen undescribed sesquiterpenes, named curcumaones A-N (1-14), as well as forty-four (15-58) known ones, were isolated from the secondary rhizomes of Curcuma wenyujin. The structures and absolute configurations of 1-14 were elucidated based on NMR spectroscopic analyses, high resolution electrospray ionization mass spectroscopy (HRESIMS) data and electronic circular dichroism (ECD) spectral analysis. Among these, five sesquiterpenes with the peroxide linkage (1-5) were obtained and the change of chemical shift between the α-C connecting the peroxide linkage and the oxygen atom has been discussed. In addition, all the isolated compounds were evaluated for their agonistic effect on farnesoid X receptors (FXR) situated with human embryonic kidney (HEK) 293T cells and the results showed that compounds 12 and 14 exhibited a significant agonistic effect dose-dependently at 20, 50 and 100 μM, while 8, 32, 17 and 34 possessed moderate to weak agonistic effects.

β-Elemene inhibits epithelial-mesenchymal transformation in non-small cell lung cancer by targeting ALDH3B2/RPSA axis

The pharmacological mechanism of β-elemene in non-small cell lung cancer (NSCLC) remains poorly understood. In this study, we identified aldehyde dehydrogenase 3B2 (ALDH3B2) as a pivotal target for β-elemene's anti-tumor effects in NSCLC by bioinformatic analysis. The overexpression of ALDH3B2 is specifically associated with the malignancy of NSCLC and the poor prognosis in patients with lung adenocarcinoma. Furthermore, we observed a positive correlation between ALDH3B2 levels and the sensitivity of cells to β-elemene. Additionally, we confirmed that β-elemene suppresses ALDH3B2 expression in PC-9 and NCI-H1373 cell lines. Notably, ALDH3B2 overexpression in NCI-H1373 cells resulted in enhanced migration, invasion, and a prominent epithelial-mesenchymal transition (EMT), which could be attenuated by β-elemene via inhibition of ALDH3B2 expression. Subsequent investigations demonstrated that ALDH3B2 overexpression upregulated ribosomal protein SA (RPSA) expression. β-elemene counteracted the upregulation of RPSA by suppressing ALDH3B2. Furthermore, knocking down of ALDH3B2 and β-elemene treatment significantly reduced the activation of protein kinase B (AKT) and extracellular signal-regulated kinase (ERK) signaling pathways via suppression of RPSA. In summary, our research uncovers that in NSCLC, ALDH3B2 functions as an oncogenic protein, promoting tumor progression. Meanwhile, β-elemene inhibits EMT of NSCLC by inhibition of ALDH3B2/RPSA axis and subsequently downregulating AKT and ERK signaling pathways. Our study highlights the significant role of ALDH3B2 in the progression of NSCLC, signifying it as a potential pharmacodynamic biomarker for β-elemene. These findings enrich the understanding of anti-tumor pharmacological mechanism of β-elemene, and provides new theoretical and experimental foundations for its potential application in the treatment of NSCLC.

Molecular and pathological landscape of the AT-rich interaction domain 1A (ARID1A) mutation in hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide, with complex etiological factors and a diverse genetic landscape. Among the critical genetic mutations in HCC, the AT-rich interaction domain 1 A (ARID1A) gene, a key component of the SWI/SNF chromatin remodeling complex, stands out due to its significant role in both tumor suppression and oncogenesis. This review comprehensively examines the molecular and pathological impacts of ARID1A mutations in HCC. ARID1A mutations, which occur in approximately 7.9 % of HCC cases, predominantly involve truncating mutations leading to loss of function. These mutations are associated with various aggressive cancer features, including larger tumor size, higher rates of metastasis, and poor prognosis. The dual role of ARID1A in HCC is context-dependent, acting as a tumor suppressor by regulating cell cycle control, DNA damage repair, and gene expression, while also displaying oncogenic properties in specific contexts by promoting early tumorigenesis through oxidative stress pathways. Understanding the molecular mechanisms of ARID1A, including its interactions with key cellular pathways such as PI3K/AKT/mTOR, β-catenin, and PD-L1, provides insights into its complex role in HCC pathogenesis. Furthermore, ARID1A's impact on cancer stem cell maintenance, metabolic reprogramming, and immune evasion underscores its potential as a therapeutic target. This review highlights the need for context-specific therapeutic strategies targeting ARID1A, which could lead to more effective treatments for HCC, addressing both its tumor-suppressive and oncogenic activities.

The processing mechanism of vinegar-processed Curcumae Rhizome enhances anti hepatic fibrotic effects through regulation of PI3K/Akt/mTOR signaling pathway

BACKGROUND

Hepatic fibrosis, a chronic pathological condition resulting from various forms of persistent liver injury, in the later stage, it can evolve into cirrhosis and even liver cancer. Curcumae Rhizoma (CR), traditionally recognized for its properties in line qi break blood, eliminate accumulation and relieve pain. According to traditional Chinese medicine (TCM) principles, vinegar-processing enhances CR's ability to enter the liver meridian and act on the blood level, potentially augmenting its therapeutic effects on hepatic diseases. Therefore, vinegar-processed Curcumae Rhizoma (VCR) is frequently employed in treating liver fibrosis and related hepatic conditions. However, the underlying mechanisms of vinegar processing in enhancing its therapeutic efficacy remain unclear.

METHODS

The anti-liver fibrosis effects of CR and VCR were verified at individual and cellular levels. Subsequently, HPLC-Q-TOFMS and pharmacokinetic analysis were utilized to elucidate the potential bioactive substances underlying the enhanced anti-fibrotic efficacy of VCR. Building upon these findings, network pharmacology and metabolomics were integrated to screen for key effect components and regulatory pathways. Finally, the mechanisms of action were further analyzed and validated at the tissue and cellular levels through Western blotting (WB) and molecular docking studies.

RESULTS

Both CR and VCR exhibited therapeutic effects against hepatic fibrosis, with VCR demonstrating enhanced efficacy after vinegar processing. 6 sesquiterpenes including furanodiene and curdione, showed significant alterations in plasma exposure and hepatic distribution post-processing. VCR significantly improved pathological liver conditions, lipid accumulation, and fibrosis severity. Additionally, VCR markedly reduced the expression of α-SMA in the liver and attenuated the elevations in liver function markers such as ALT and AST. Combined network pharmacology, metabolomics, and hepatic tissue WB analysis revealed that the reduced phosphorylation of the PI3K/Akt/mTOR pathway is a critical mechanism in VCR's anti-fibrotic effects. Experiments on LX-2 cells demonstrated that four sesquiterpenes, including furanodiene and curdione, effectively inhibited the proliferation of activated hepatic stellate cells (HSCs). Furanodiene, in particular, promoted apoptosis in activated HSCs by reducing phosphorylation levels of the PI3K/Akt/mTOR pathway proteins, increasing BAX expression, and activating downstream caspase-3 to achieve the effect of anti-liver fibrosis.

CONCLUSION

Vinegar-processing significantly increases the plasma exposure and hepatic distribution of components such as furanodiene in VCR, enhancing anti-fibrotic efficacy by downregulating the phosphorylation levels of the PI3K/Akt/mTOR pathway and promoting HSC apoptosis. This study provides a comprehensive explanation of the vinegar-processing mechanism and its role in enhancing the anti-fibrotic effects of VCR, offering insights for its clinical application in liver fibrosis treatment and reference for the mechanistic study of other vinegar-processed herbal medicines.

Exploring the interaction of curcumin with β-cyclodextrin and its binding with DNA: A combined spectroscopic and molecular docking study

At present, a major effort in biophysical studies has been paid towards exploring the interactions and release of therapeutic payloads to the specific site leaving behind healthy cells unaffected and hence, lower the drug-induced toxicity. For the purpose, interaction of β-bound CUR with calf thymus DNA (ctDNA) has been examined intensely using a series of biophysical methods like absorption, steady state fluorescence emission, and circular dichroism together with molecular docking study. The experimental analysis divulge that CUR interacts with both β-CD (although with different molar ratio) and DNA. However, the binding affinity of CUR with the target (DNA) is higher than it does with the β-CD. When β-CD-carried (10 mM) CUR (μM) (inclusion complex) comes near DNA (15-372 μM), CUR gets out from β-CD's void and approaches to binds with the DNA. The relocation of the probe occurred due to competitive binding of the CUR between β-CD and the DNA. The present investigation may provide a simple yet probable route for the transfer of encapsulated therapeutic payload of β-CD to the most relevant biomolecular target DNA.

Exploration of potential antidiabetic and antioxidant components from the branches of Mitragyna diversifolia and possible mechanism

In this study, sixteen compounds were isolated from the branches of Mitragyna diversifolia, including twelve triterpenes (1-12), a phenolic compound (13), and three flavonoids (14-16). Among them, compounds 1-7, and 10-16 were reported for the first time from this plant. Compounds 7, 14, and 15 exhibited significant inhibitory activities against α-glucosidase, with IC50 values of 18.48 ± 2.74, 12.14 ± 1.58 and 35.77 ± 4.52 µM, respectively. Furthermore, the inhibitory kinetics of α-glucosidase revealed that all fractions, active compounds 7, 14, and 15 belong to the mix inhibition type. In molecular docking, the analysis showed that compounds 13, 14, 15, and 16 possessed superior binding capacities with α-glucosidase (-8.3, -9.6, -9.9, and -9.2 kcal/mol, respectively). The results of the glucose uptake experiment indicated that only compound 14 showed a significant promotion effect on the glucose uptake rate of 3T3-L1 adipocytes (P < 0.05). Meanwhile, compounds 13, 14, 15, and 16 possessed potent antioxidant abilities with DPPH, ABTS, and FRAP. In DNA and protein oxidative damage assays, compound 15 had a stronger effect than the positive control Vc. The network-based pharmacological analysis platform was used to predict the diabetes-related target proteins of active compounds 7, 13, 14, 15, and 16, and two candidate targets (ALB and PPARG) related to their therapeutic effects on diabetes were identified.

Targeting the p53-p21 axis in liver cancer: Linking cellular senescence to tumor suppression and progression

Liver cancer is a major health epidemic worldwide, mainly due to its high mortality rates and limited treatment options. The association of cellular senescence to tumorigenesis and the cancer hallmarks remains a subject of interest in cancer biology. The p53-p21 signalling axis is an important regulator in restoring the cell's balance by supporting tumor suppression and tumorigenesis in liver cancer. We review the novel molecular mechanisms that p53 and its downstream effector, p21, employ to induce cellular senescence, making it last longer, and halt the proliferation of damaged hepatocytes to become tumorous cells. We also examine how dysregulation of this pathway contributes to HCC pathogenesis, proliferation, survival, acquired resistance to apoptosis, and increased invasiveness. Furthermore, we comprehensively describe the molecular cross-talk between the p53-p21 signalling axis and major cell cycle signalling pathways, including Wnt/β-catenin, PI3K/Akt, and TGF-β in liver cancer and provide an overview of promising candidates for chemoprevention and future therapeutic strategies. This review article explores the roles of the p53-p21 pathway in liver cancer, examining its function in promoting cellular senescence under normal conditions and its potential role in cancer progression. It also highlights novel therapeutic drugs and drug targets within the pathway and discusses the implications for treatment strategies and prognosis in liver cancer.

Seaweed-derived laminarin and alginate as potential chemotherapeutical agents: An updated comprehensive review considering cancer treatment

Seaweed-derived bioactive substances such as polysaccharides have proven to be effective chemotherapeutic and chemopreventive agents. Laminarin and alginate antioxidant properties aid in the prevention of cancer through dynamic modulation of critical intracellular signaling pathways via apoptosis which produce low cytotoxicity and potential chemotherapeutic effects. Understanding the effects of laminarin and alginate on human cancer cells and their molecular roles in cell death pathways can help to develop a novel chemoprevention strategy. This review emphasizes the importance of apoptosis-modulating laminarin and alginate in a range of malignancies as well as their extraction, molecular structure, and weight. In addition, future nano-formulation enhancements for greater clinical efficacy are discussed. Laminarin and alginate are perfect ingredients because of their distinct physicochemical and biological characteristics and their use-based delivery systems in cancer. The effectiveness of laminarin and alginate against cancer and more preclinical and clinical trials will open up as new chemotherapeutic natural drugs which lead to established as potential cancer drugs.

Heat shock proteins (HSPs) in non-alcoholic fatty liver disease (NAFLD): from molecular mechanisms to therapeutic avenues

Non-alcoholic fatty liver disease (NAFLD), a spectrum of liver conditions characterized by fat accumulation without excessive alcohol consumption, represents a significant global health burden. The intricate molecular landscape underlying NAFLD pathogenesis involves lipid handling, inflammation, oxidative stress, and mitochondrial dysfunction, with endoplasmic reticulum (ER) stress emerging as a key contributor. ER stress triggers the unfolded protein response (UPR), impacting hepatic steatosis in NAFLD and contributing to inflammation, fibrosis, and progression to NASH and eventually hepatocellular carcinoma (HCC). Heat shock proteins (HSPs), including small HSPs such as HSP20 and HSP27, HSP60, HSP70, GRP78, and HSP90, are integral to cellular stress responses. They aid in protein folding, prevent aggregation, and facilitate degradation, thus mitigating cellular damage under stress conditions. In NAFLD, aberrant HSP expression and function contribute to disease pathogenesis. Understanding the specific roles of HSP subtypes in NAFLD offers insights into potential therapeutic interventions. This review discusses the involvement of HSPs in NAFLD pathophysiology and highlights their therapeutic potential. By elucidating the molecular mechanisms underlying HSP-mediated protection in NAFLD, this article aims to pave the way for the development of targeted therapies for this prevalent liver disorder.

GA receptor targeted chitosan oligosaccharide polymer nanoparticles improve non-alcoholic fatty liver disease by inhibiting ferroptosis

Excessive iron in the liver may exacerbate Non-alcoholic fatty liver disease (NAFLD) by increasing the risk of liver cell expansion, inflammation and fibrosis. Ferroptosis in liver cells may lead the progression of simple fatty liver degeneration to steatohepatitis (NASH). More and more studies shew that ferroptosis played a crucial role in the pathological process of NAFLD. Based on the mechanism of ferroptosis, this study first synthesized a liver targeted 18-β-Glycyrrhetinic-acid-chitosan oligosaccharide -N-acetylcysteine polymer (GCNp), and further curcumin (Cur) was used as model drug to prepare Cur loaded nanodelivery system (GCNp-Cur NPs). The particle size of GCNp-Cur NPs was 132.5 ± 9.8 nm, PDI was 0.148 ± 0.026 and the potential was 23.8 mV. GCNp-Cur NPs can regulate the GPX4/GSH pathway, inhibit lipid peroxidation, restore cellular oxidative environment, reduce free Fe2+, improve cellular lipid metabolism and iron metabolism, thereby NPs inhibited liver cell ferroptosis through multiple pathways. Additionally, GCNp-Cur NPs could also alleviate liver tissue lipid accumulation and oxidative damage, delaying disease progression, and providing a new method and theoretical basis for the treatment of NAFLD.

Emodin repairs interstitial cells of Cajal damaged by cholelithiasis in the gallbladder

Background

Hypercholesterolemia induces cholelithiasis and dysfunction of gallbladder motility. Interstitial cells of Cajal (ICCs) contribute to gallbladder motility. Emodin modulates the contractility of the gallbladder muscle; however, the underlying mechanism is unknown.

Aim

This study aimed to explore the effects of emodin on gallbladder ICCs with cholelithiasis in a guinea pig model.

Methods

Animals were randomly divided into a healthy control group and three study groups. All study groups received a high-cholesterol diet (HCD) for 8 weeks. Subsequently, they were randomly assigned to either the HCD group or one of the emodin treatment groups lasting 4 or 8 weeks. Total cholesterol (TC) and triglycerides (TG) were measured to determine changes in serum lipid levels. Immunohistochemistry was performed to detect the morphology and number of ICCs. TUNEL assays were performed to detect ICC apoptosis. Transmission electron microscopy was employed to observe ICC structure. Western blotting and real-time polymerase chain reaction were used to detect changes in stem cell factor (SCF)/c-kit pathway expression.

Results

Serum TC and TG were higher in all study groups. In cases of cholelithiasis, the SCF/c-kit pathway was downregulated, the number of gallbladder ICCs decreased, apoptosis increased, and the ICC network structure was damaged. After emodin treatment, the SCF/c-kit pathway was upregulated, the number of gallbladder ICCs increased, apoptosis decreased, and the ICC network structure recovered.

Conclusion

Cholelithiasis downregulates the SCF/c-kit pathway and damages gallbladder ICCs. Emodin upregulates the SCF/c-kit pathway and increases gallbladder ICCs, contributing to recovery from gallbladder motility disorders.\.

Melatonin for gastric cancer treatment: where do we stand?

Gastric cancer (GC) is the third leading reason of death in men and the fourth in women. Studies have documented an inhibitory function of melatonin on the proliferation, progression and invasion of GC cells. MicroRNAs (miRNAs) are small, non-coding RNAs that play an important function in regulation of biological processes and gene expression of the cells. Some studies reported that melatonin can suppress the progression of GC by regulating the exosomal miRNAs. Thus, melatonin represents a promising potential therapeutic agent for subjects with GC. Herein, we evaluate the existing data of both in vivo and in vitro studies to clarify the molecular processes involved in the therapeutic effects of melatonin in GC. The data emphasize the critical function of melatonin in several signaling ways by which it may inhibit cancer cell proliferation, decrease chemo-resistance, induce apoptosis as well as limit invasion, angiogenesis, and metastasis. This review provides a resource that identifies some of the mechanisms by which melatonin controls GC enlargement. In light of the findings, melatonin should be considered a novel and testable therapeutic mediator for GC treatment.

The hepatorenal protective effects of silymarin in cancer patients receiving chemotherapy: a randomized, placebo-controlled trial

BACKGROUND

Breast cancer is one of the most common diseases globally that may have side effects on liver and renal function. Pharmacological treatments to reduce adverse liver and renal effects are still limited. It has been proposed that silymarin may possess hepatoprotective and anti-inflammatory properties. The present trial aims to assess the hepatorenal protective efficacy of silymarin supplementation in cancer patients receiving chemotherapy in an outpatient setting.

METHOD

This is a randomized, placebo-controlled clinical trial that recruited female breast cancer patients. Participants were randomly assigned to one placebo group and two intervention groups. The control group received 140 mg of placebo daily, while the two intervention groups received 140 mg silymarin daily. Follow-up assessments were conducted at baseline, 3 weeks, and 6 weeks. At the beginning of the study, the patients were subjected to a computed tomography (CT) scan, and the liver and renal parameters such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), bilirubin, Blood urea nitrogen (BUN) and Creatinine (Cr) were examined through laboratory tests.

RESULTS

Despite two deaths and three dropouts, 100 patients completed the study. Silymarin showed significant effects on liver enzymes in the levels of ALP and bilirubin (P < 0.05), with no significant impact on renal function in the levels of Blood urea nitrogen (BUN) and Creatinine (Cr) (P > 0.05). The medication was well-tolerated, with minimal reported side effects (P > 0.05).

DISCUSSION

The study suggests that silymarin may have hepato-renal protective potential in breast cancer patients and improve patient tolerance to chemotherapy. The data presented on the efficacy and safety of silymarin may provide stronger foundation for further trials and for a possible use in clinical practice.

Association between thyroid disorders and extra-thyroidal cancers, a review

Thyroid hormone has been shown to have both tumor-promoting and tumor-suppressing actions, which has led to significant debate over its involvement in the development of cancer. Proliferation, apoptosis, invasiveness, and angiogenesis are all aspects of cancer that are affected by the thyroid hormones T3 and T4, according to research conducted in animal models and in vitro experiments. The effects of thyroid hormones on cancer cells are mediated by many non-genomic mechanisms, one of which involves the activation of the plasma membrane receptor integrin αvβ3. Typically, abnormal amounts of thyroid hormones are linked to a higher occurrence of cancer. Both benign and malignant thyroid disorders were found to be associated with an increased risk of extra-thyroidal malignancies, specifically colon, breast, prostate, melanoma, and lung cancers. The purpose of this review was to shed light on this link to define which types of cancer are sensitive to thyroid hormones and, as a result, are anticipated to respond favorably to treatment of the thyroid hormone axis.

The Effectiveness of Curcumin Nanoparticle-Coated Titanium Surfaces in Osteogenesis: A Systematic Review

(1) Background: This systematic review critically appraises and synthesizes evidence from in vitro studies investigating the effects of curcumin nanoparticles on titanium surface modification, focusing on cell adhesion, proliferation, osteogenic differentiation, and mineralization. (2) Methods: A comprehensive electronic search was conducted in PubMed, Cochrane Central Register of Controlled Trials, and Google Scholar databases, yielding six in vitro studies that met the inclusion criteria. The search strategy and study selection process followed PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A qualitative methodological assessment was performed using the SciRAP (Science in Risk Assessment and Policy) method, which evaluated the reporting and methodological quality of the included studies. (3) Results: All six studies consistently demonstrated that curcumin-coated titanium surfaces inhibited osteoclastogenesis and promoted osteogenic activity, evidenced by enhanced cell adhesion, proliferation, osteogenic differentiation, and mineralization. The mean reporting quality score was 91.8 (SD = 5.7), and the mean methodological quality score was 85.8 (SD = 10.50), as assessed by the SciRAP method. Half of the studies used hydroxyapatite-coated titanium as a control, while the other half used uncoated titanium, introducing potential variability in baseline comparisons. (4) Conclusions: This systematic review provides compelling in vitro evidence supporting the osteogenic potential of curcumin nanoparticle-coated titanium surfaces. The findings suggest that this surface modification strategy may enhance titanium implants' biocompatibility and osteogenic properties, potentially improving dental and orthopedic implant outcomes. However, the review highlights significant heterogeneity in experimental designs and a concentration of studies from a single research group. Further research, particularly in vivo studies and clinical trials from diverse research teams, is essential to validate these findings and comprehensively understand the translational potential of this promising surface modification approach.

Shining insights: Deciphering the biogenic synthesis of Ajuga bracteosa-mediated gold nanoparticles with advanced microscopy techniques

In this study, gold nanoparticles (AuNPs) were bioreduced from Ajuga bracteosa, a medicinal herb known for its therapeutic properties against various diseases. Different fractions of the plant extract were used, including the methanolic fraction (ABMF), the n-hexane fraction (ABHF), the chloroform fraction (ABCF), and the aqueous extract for AuNPs synthesis. The characterization of AuNPs was performed using UV-Vis spectrophotometry, FT-IR, XRD, EDX, and TEM. UV-Vis spectroscopy confirmed the formation of AuNPs, with peaks observed at 555 nm. FT-IR analysis indicated strong capping of phytochemicals on the surface of AuNPs, which was supported by higher total phenolic contents (TPC) and total flavonoid contents (TFC) in AuNPs. XRD results showed high crystallinity and a smaller size distribution of AuNPs. TEM analysis revealed the spherical shape of AuNPs, with an average size of 29 ± 10 nm. The biologically synthesized AuNPs exhibited superior antibacterial, antioxidant, and cytotoxic activities compared to the plant extract fractions. The presence of active biomolecules in A. bracteosa, such as neoclerodan flavonol glycosides, diterpenoids, phytoecdysone, and iridoid glycosides, contributed to the enhanced biological activities of AuNPs. Overall, this research highlights the potential of A. bracteosa-derived AuNPs for various biomedical applications due to their remarkable therapeutic properties and effective capping by phytochemicals. RESEARCH HIGHLIGHTS: This research underscores the growing significance of herbal medicine in contemporary healthcare by exploring the therapeutic potential of Ajuga bracteosa and gold nanoparticles (AuNPs). The study highlights the notable efficacy of A. bracteosa leaf extracts and AuNPs in treating bacterial infections, demonstrating their bactericidal effects on a range of strains. The anti-inflammatory properties of plant extracts and nanoparticles are evidenced through paw edema method suggesting their applicability in managing inflammatory conditions. These findings position A. bracteosa and AuNPs as potential candidates for alternative and effective approaches to modern medication.

From diagnosis to therapy: The critical role of lncRNAs in hepatoblastoma

According to findings, long non-coding RNAs (lncRNAs) serves an integral part in growth and development of a variety of human malignancies, including Hepatoblastoma (HB). HB is a rare kind of carcinoma of the liver that mostly affects kids and babies under the age of three. Its manifestations include digestive swelling, abdominal discomfort, and losing weight. This thorough investigation digs into the many roles that lncRNAs serve in HB, giving views into their varied activities as well as possible therapeutic consequences. The function of lncRNAs in HB cell proliferation, apoptosis, migratory and penetrating capacities, epithelial-mesenchymal transition, and therapy tolerance is discussed. Various lncRNA regulatory roles are investigated in depth, yielding information on their effect on essential cell processes such as angiogenesis, apoptosis, immunity, and growth. Circulating lncRNAs are currently acknowledged as potential indications for the initial stages of identification of cancer, with the ability to diagnose as well as forecast. In addition to their diagnostic utility, lncRNAs provide curative opportunities as locations and actors, contributing to the expanding landscape of cancer research. Several HB-linked lncRNAs have been demonstrated to exhibit abnormal expression and are involved in tumor-like characteristics via DNA, RNA, or protein binding or encoding short peptides. As a result, a better knowledge of lncRNA instability might bring fresh perspectives into HB etiology as well as innovative strategies for HB early diagnosis and therapy. We describe the abnormalities of lncRNA expression in HB and their tumor-suppressive or carcinogenic activities during HB carcinogenesis in this study. Furthermore, we explore lncRNAs' diagnostic and therapeutic possibilities in HB.

Targeting ferroptosis regulators in lung cancer: Exploring natural products

Lung cancer remains a formidable global health challenge, necessitating innovative therapeutic strategies for improved efficacy. This review explores the untapped potential of natural products and Traditional Chinese Medicine (TCM) in lung cancer therapy, focusing on targeting ferroptosis regulators. Natural compounds, such as curcumin and resveratrol, exhibit diverse anti-cancer mechanisms, complemented by TCM's holistic approach rooted in a 3500-year history. Emphasizing the induction of cell death, particularly ferroptosis, the review highlights its significance in overcoming challenges like resistance to conventional therapies. Key ferroptosis regulators are explored in the context of natural products and TCM. The impact of these treatments on crucial pathways, such as antioxidant mechanisms (GPX4, SLC7A11, and NRF2), iron metabolism regulators, and lipid and mitochondria pathways, is examined. The findings provide a comprehensive overview of how natural products and TCM modulate ferroptosis in lung cancer, offering valuable insights for the development of innovative, side-effect-reduced therapeutic strategies. This work holds promise for transforming the landscape of lung cancer treatment by integrating the rich resources of nature into conventional therapeutic paradigms.

Anti-Oxidative and Anti-Apoptotic Oligosaccharides from Pichia pastoris-Fermented Cress Polysaccharides Ameliorate Chromium-Induced Liver Toxicity

Oxidative stress impairs the structure and function of the cell, leading to serious chronic diseases. Antioxidant-based therapeutic and nutritional interventions are usually employed for combating oxidative stress-related disorders, including apoptosis. Here, we investigated the hepatoprotective effect of oligosaccharides, produced through Pichia pastoris-mediated fermentation of water-soluble polysaccharides isolated from Lepidium sativum (cress) seed mucilage, on chromium(VI)-induced oxidative stress and apoptosis in mice. Gel permeation chromatography (GPC), using Bio-Gel P-10 column, of the oligosaccharides product of fermentation revealed that P. pastoris effectively fermented polysaccharides as no long chain polysaccharides were observed. At 200 µg/mL, fractions DF73, DF53, DF72, and DF62 exhibited DPPH radical scavenging activity of 92.22 ± 2.69%, 90.35 ± 0.43%, 88.83 ± 3.36%, and 88.83 ± 3.36%, respectively. The antioxidant potential of the fermentation product was further confirmed through in vitro H2O2 radical scavenging assay. Among the screened samples, the highest H2O2 radical scavenging activity was displayed by DF73, which stabilized the free radicals by 88.83 ± 0.38%, followed by DF53 (86.48 ± 0.83%), DF62 (85.21 ± 6.66%), DF72 (79.9 4± 1.21%), and EPP (77.76 ± 0.53%). The oligosaccharide treatment significantly alleviated chromium-induced liver damage, as evident from the increase in weight gain, improved liver functions, and reduced histopathological alterations in the albino mice. A distinctly increased level of lipid peroxide (LPO) free radicals along with the endogenous hepatic enzymes were evident in chromium induced hepatotoxicity in mice. However, oligosaccharides treatment mitigated these effects by reducing the LPO production and increasing ALT, ALP, and AST levels, probably due to relieving the oxidative stress. DNA fragmentation assays illustrated that Cr(VI) exposure induced massive apoptosis in liver by damaging the DNA which was then remediated by oligosaccharides supplementation. Histopathological observations confirmed that the oligosaccharide treatment reverses the architectural changes in liver induced by chromium. These results suggest that oligosaccharides obtained from cress seed mucilage polysaccharides through P. pastoris fermentation ameliorate the oxidative stress and apoptosis and act as hepatoprotective agent against chromium-induced liver injury.

Investigation on the lipid-lowering effect and mechanism by combining turmeric with hawthorn in C57BL/6 obese mice

Study on the hypolipidemic effect of turmeric combined with hawthorn on C57BL/6 obese mice and its possible mechanism. C57 mice were fed with 60% high-fat diet for 8 weeks to establish an obesity model, and 4 mice were slaughtered to verify whether the modeling was successful. The successful mice were divided into model group (HFD), positive group (high fat feed group [HFD] + simvastatin group [SIM]), turmeric group (HFD + TUR), hawthorn group (HFD + HAW), and para-medicine group (HFD + para-drug group [DOU]) for 4 weeks by gavage intervention. Different intervention groups had certain lipid-lowering effects, and the para-medicine group showed significant differences (p < 0.05, p < 0.01, p < 0.001) in reducing serum total cholesterol, triglycerides, low-density lipoprotein cholesterol, glutamic acid transaminase (ALT), glutamic acid transaminase (AST), and increasing high-density lipoprotein cholesterol. In the para-medicine group, the protein expression of peroxisome proliferator-activated receptor γ, fatty acid synthase, platelet-reactive protein receptor 36, and CCAAT/enhancer binding protein α were significantly downregulated, and the protein expression of carnitine palmitoyl transferase1 and peroxisome proliferator-activated receptor α protein expression (p < 0.01, p < 0.001), thus suggesting that turmeric and hawthorn are superior to turmeric and hawthorn alone in enhancing lipid metabolism-related mechanisms. Combined effects of turmeric and hawthorn improve lipid metabolism in mice, protect the liver, and improve the protein expression of liver-related genes. This study can lay the theoretical basis for the future association of medicinal food products and the development of related weight loss products.

Ferroptosis in Cancer Therapy: Mechanisms, Small Molecule Inducers, and Novel Approaches

Ferroptosis, a unique form of programmed cell death, is initiated by an excess of iron accumulation and lipid peroxidation-induced damage. There is a growing body of evidence indicating that ferroptosis plays a critical role in the advancement of tumors. The increased metabolic activity and higher iron levels in tumor cells make them particularly vulnerable to ferroptosis. As a result, the targeted induction of ferroptosis is becoming an increasingly promising approach for cancer treatment. This review offers an overview of the regulatory mechanisms of ferroptosis, delves into the mechanism of action of traditional small molecule ferroptosis inducers and their effects on various tumors. In addition, the latest progress in inducing ferroptosis using new means such as proteolysis-targeting chimeras (PROTACs), photodynamic therapy (PDT), sonodynamic therapy (SDT) and nanomaterials is summarized. Finally, this review discusses the challenges and opportunities in the development of ferroptosis-inducing agents, focusing on discovering new targets, improving selectivity, and reducing toxic and side effects.

Study of some graph theoretical parameters for the structures of anticancer drugs

Eigenvalues have great importance in the field of mathematics, and their relevance extends beyond this area to include several other disciplines such as economics, chemistry, and numerous fields. According to our study, eigenvalues are utilized in chemistry to express a chemical compound's numerous physical properties as well as its energy form. It is important to get a comprehensive understanding of the interrelationship underlying mathematics and chemistry. The anti-bonding phase is correlated with positive eigenvalues, whereas the bonding level is connected with negative eigenvalues. Additionally, the non-bonded level corresponds to eigenvalues of zero. This study focuses on the analysis of various structures of anticancer drugs, specifically examining their characteristic polynomials, eigenvalues of the adjacency matrix, matching number and nullity. Consequently, the selected structures of the aforementioned anticancer drugs exhibit stability since they are composed of closed-shell molecules, characterized by a nullity value of zero.

Curcuma wenyujin rhizomes extract ameliorates lipid accumulation

Curcuma wenyujin (C. wenyujin) is a medicinal plant that is traditionally used to treat blood stagnation, liver fibrosis, pain, and jaundice. In this study, we examined the effect of C. wenyujin rhizome extract on hepatic lipid accumulation both in vivo and in vitro. We found that the petroleum ether fraction of C. wenyujin rhizome extract (CWP) considerably reduced the accumulation of lipids in HepG2 cells treated with oleic and palmitic acid. Ultra-high-performance liquid chromatography coupled with LTQ-Orbitrap mass spectrometry was used to analyze the main chemical constituents of CWP, and 21 sesquiterpenes were identified. In vivo experiments revealed that the administration of CWP significantly reduced the body weight and serum total cholesterol (TC) level of low-density-lipoprotein receptor knockout mice treated with a high-fat diet without affecting their food intake. CWP also significantly reduced the levels of liver TC, liver triglycerides, aspartate transaminase, and alanine transaminase. Histological examination revealed that CWP dose-dependently reduced steatosis in liver tissue, significantly downregulated the expression of lipogenesis genes, and increased the β-oxidation of fatty acids. CWP also significantly increased autophagy-related proteins. In conclusion, CWP rich in sesquiterpenes reduces the accumulation of lipids in vivo and in vitro by improving lipid metabolism and activating autophagy.

Network pharmacology prediction and experiment validation of anti-liver cancer activity of Curcumae Rhizoma and Hedyotis diffusa Willd

Objective

This study aims to elucidate anti-liver cancer components and potential mechanisms of Curcumae Rhizoma and Hedyotis diffusa Willd (CR-HDW).

Methods

Effective components and targets of CR-HDW were identified from the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database. Liver cancer-related genes were collected from GeneCards, Gene-Disease Association (DisGeNET), and National Center for Biotechnology Information (NCBI). Protein-protein interaction networks, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment were conducted to analyze the identified genes. Molecular docking was used to simulate binding of the active components and their target proteins. Cell activity assay, western blot, and senescence-associated β-galactosidase (SA-β-gal) experiments were conducted to validate core targets identified from molecular docking.

Results

Ten active compounds of CR-HDW were identified including quercetin, 3-epioleanic acid and hederagenin. The primary core proteins comprised Glyceraldehyde-3-phosphate dehydrogenase (GAPDH), Protein Kinase B(AKT1), etc. The pathways for Phosphoinositide 3-kinase (PI3K)/ AKT, cellular senescence, Fork head boxO (FOXO) were revealed as important for anti-cancer activity of CR-HDW. Molecular docking demonstrated strong binding between liver cancer target proteins and major active components of CR-HDW. In-vitro experiments confirmed that hederagenin and 3-epioleolic acid inhibited HuH-7 cell growth, reduced expression of PI3K, AKT, and mechanistic target of rapamycin (mTOR) proteins. Hederagenin also induced HuH-7 senescence.

Conclusions

In summary, The authors' results suggest that the CR-HDW component (Hederagenin, 3-epoxy-olanolic acid) can inhibit the proliferation of HuH-7 cells by decreasing PI3K, AKT, and mTOR. Hederagenin also induced HuH-7 senescence.

Recent advances in natural nanoclay for diagnosis and therapy of cancer: A review

Cancer is still one of the deadliest diseases, and diagnosing and treating it effectively remains difficult. As a result, advancements in earlier detection and better therapies are urgently needed. Conventional chemotherapy induces chemoresistance, has non-specific toxicity, and has a meager efficacy. Natural materials like nanosized clay mineral formations of various shapes (platy, tubular, spherical, and fibrous) with tunable physicochemical, morphological, and structural features serve as potential templates for these. As multifunctional biocompatible nanocarriers with numerous applications in cancer research, diagnosis, and therapy, their submicron size, individual morphology, high specific surface area, enhanced adsorption ability, cation exchange capacity, and multilayered organization of 0.7-1 nm thick single sheets have attracted significant interest. Kaolinite, halloysite, montmorillonite, laponite, bentonite, sepiolite, palygorskite, and allophane are the most typical nanoclay minerals explored for cancer. These multilayered minerals can function as nanocarriers to effectively carry a variety of anticancer medications to the tumor site and improve their stability, dispersibility, sustained release, and transport. Proteins and DNA/RNA can be transported using nanoclays with positive and negative surfaces. The platform for phototherapeutic agents can be nanoclays. Clays with bio-functionality have been developed using various surface engineering techniques, which could help treat cancer. The promise of nanoclays as distinctive crystalline materials with applications in cancer research, diagnostics, and therapy are examined in this review.

The raw and vinegar-processed Curcuma phaeocaulis Val. ameliorate TAA-induced zebrafish liver injury by inhibiting TLR4/MyD88/NF-κB signaling pathway

ETHNOPHARMACOLOGICAL RELEVANCE

Liver injury, the main factor in the pathogenesis of most liver diseases, is a known contributor to acute liver failure, liver fibrosis, or liver cancer. Curcuma phaeocaulis Val. (PEZ) has been broadly used in treating liver injury with satisfying therapeutic effects; however, the mechanism is still unclear.

AIM OF THE STUDY

This study aimed to explore the mechanism of PEZ in ameliorating thioacetamide (TAA)-induced zebrafish liver injury based on a comprehensive method integrating network-based computational prediction and experimental validations.

MATERIALS AND METHODS

Ultrahigh-performance liquid chromatography-quadrupole exactive mass spectrometry/mass spectrometry (UPLC-Q-Exactive MS/MS) analysis was used to analyze components in raw and vinegar-processed PEZ (VPEZ). Network pharmacology was used to construct a compound-target network for liver injury to predict the possible biological targets of PEZ along with potential signaling pathways. TAA-induced zebrafish larvae liver injury model was established, and the anti-liver injury effect of PEZ by a series of indexes was measured, including liver phenotype analysis, histopathological analysis of liver tissues, and biochemical indexes analysis. Remarkably, the predicted pathway by network pharmacology was further validated using RT-qPCR and Western blotting analyzes in animal experiments.

RESULTS

40 chemical constituents derived from PEZ were identified, while 45 chemical components derived from VPEZ were identified. Based on it, 565 genes related to these identified compounds in PEZ and 1023 genes linked to liver injury were collected by network pharmacology. Critically, KEGG analysis indicated that the TLR4/MyD88/NF-κB signaling pathway was recommended as one of the main pathways related to the anti-liver injury effect of PEZ. Experimentally, PEZ could alleviate TAA-induced liver injury. Compared to the liver injury model group without any treatment, the treatment of PEZ significantly reduced the expression of both mRNA and protein targets in the TLR4/MyD88/NF-κB signaling pathway. In addition, the effect of VPEZ was more significant than that of the raw one.

CONCLUSION

The raw and vinegar-processed PEZ could ameliorate TAA-induced zebrafish liver injury through TLR4/MyD88/NF-κB signaling pathway.

Herb pairs containing Curcumae Rhizoma (Ezhu): A review of bio-active constituents, compatibility effects and t-copula function analysis

ETHNOPHARMACOLOGICAL RELEVANCE

An herbal pair is a classic form of clinical dispensing in Traditional Chinese Medicine (TCM), often used in prescriptions to enhance the effect or reduce potential side effects. It is the smallest component unit of Chinese medicine prescription and an essential bridge between Chinese medicine and prescription. Curcumae Rhizoma (called Ezhu in Chinese) is a representative TCM herb that promotes blood circulation and removes blood stasis. It has been used in Chinese medicine for thousands of years. Ezhu is generally used in clinical applications as a part of a "drug pair" to treat heartburn, stomach pain, tumour, amenorrhea and abdominal pain caused by blood stasis, qi stagnation and injury.

AIMS OF THE REVIEW

This review aims to summarize the latest and comprehensive situation of the biological activity and clinical application of drug pairs containing Ezhu, find the law of Ezhu compatibility application, and discuss the rationalization of Ezhu drug compatibility. For Ezhu, herb pairs to provide a theoretical basis for clinical research in TCM and serve as a research foundation for developing new drugs.

MATERIALS AND METHODS

Using a self-built prescription database and Apriori algorithm for association rule mining. A systematic search for studies on herb pairs containing Ezhu was carried out by using the internet databases of PubMed, CNKI, Baidu Scholar, Google Scholar and Web of Science, as well as other relevant textbooks, reviews and documents (e.g. Chinese Pharmacopoeia, 2020 edition, Chinese herbal classic books and PhD and MSc theses, etc.). Among them with keywords including "Curcumae Rhizoma", "Ezhu", "herb pairs", "clinical application", etc. and their combinations. Moreover, the t-copula function was used to analyse the dose-coupling effect of five drug pairs, including Ezhu.

RESULTS

The preliminary statistical analysis retrieved Ezhu prescriptions from self-built prescription database and internet databases. The results showed that the compatibility frequency of Ezhu with the other five Chinese medicines was high. Most of these selected herbal combinations are used to treat internal diseases. In this paper, the progress of the ethnopharmacology of Ezhu was reviewed, emphasizing the changes in bioactive components and compatibility of Chinese traditional medicine combinations such as Ezhu and Astragalus Curcuma (Sparganium stoloniferum Buch. -Ham; called Sanleng in Chinese), Ezhu and Astragali Radix (Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao, Astragalus membranaceus (Fisch.) Bge.; called Huangqi in Chinese).

The Indispensable Roles of GMDS and GMDS-AS1 in the Advancement of Cancer: Fucosylation, Signal Pathway and Molecular Pathogenesis

Fucosylation is facilitated by converting GDP-mannose to GDP-4-keto-6-deoxymannose, which GDP-mannose 4,6-dehydratase, a crucial enzyme in the route, carries out. One of the most prevalent glycosylation alterations linked to cancer has reportedly been identified as fucosylation. There is mounting evidence that GMDS is intimately linked to the onset and spread of cancer. Furthermore, the significance of long-chain non-coding RNAs in the development and metastasis of cancer is becoming more well-recognized, and the regulatory mechanism of lncRNAs has emerged as a prominent area of study in the biological sciences. GMDS-AS1, an antisense RNA of GMDS, was discovered to have the potential to be an oncogene. We have acquired and analyzed relevant data to understand better how GMDS-AS1 and its lncRNA work physiologically and in tumorigenesis and progression. Additionally, we have looked into the possible effects of these molecules on cancer treatment approaches and patient outcomes. The physiological roles and putative processes of GMDS and lncRNA GMDS-AS1 throughout the development and progression of tumors have been assembled and examined. We also examined how these chemicals might affect patient prognosis and cancer therapy approaches. GMDS and GMDS-AS1 were determined to be research subjects by searching and gathering pertinent studies using the PubMed system. The analysis of these research articles demonstrated the close relationship between GMDS and GMDS-AS1 and tumorigenesis and the factors that influence them. GMDS plays a vital role in regulating fucosylation. The related antisense gene GMDS-AS1 affects the biological behaviors of cancer cells through multiple pathways, including the key processes of proliferation, migration, invasion, and apoptosis, providing potential biomarkers and therapeutic targets for cancer treatment and prognosis assessment.

Resveratrol attenuated fatty acid synthesis through MAPK-PPAR pathway in red tilapia

High-fat (HF) diets have been shown to cause hepatic impairment in fish species, but the mode of action, especially the pathways involved, has not yet been determined. In this study, the effects of resveratrol (RES) supplementation on the hepatic structure and fat metabolism of red tilapia (Oreochromis niloticus) were determined. Based on transcriptome and proteomics results, RES was found to promote fatty acid β-oxidation in the blood, liver, and liver cells associated with apoptosis and the MAPK/PPAR signaling pathway. RES supplementation was found to alter the expression of genes related to apoptosis and fatty acid pathways like blood itga6a and armc5 which were upregulated and downregulated respectively by high-fat feeding while ggh and ensonig00000008711 increased and decreased, respectively, with RES addition. Relative to the PPAR signaling pathway, fabp10a and acbd7 showed a reverse U-shaped tendency, both in different treatments and at different times. Proteomics results demonstrated that MAPK/PPAR, carbon/glyoxylate, dicarboxylate/glycine serine, and threonine/drug-other enzymes/beta-alanine metabolism pathways in the RES group were significantly affected, and Fasn and Acox1 decreased and increased, respectively, with RES addition. Seven subgroups were obtained using scRNA-seq, and enrichment analysis showed that the PPAR signaling pathway was upregulated with RES supplementation. RES significantly increased the expression of the marked genes (pck1) ensonig00000037711, fbp10a, granulin, hbe1, and zgc:136461, which are liver cell-specific genes. In conclusion, RES resulted in significantly enriched DGEs associated with fat metabolism and synthesis via the MAPK-PPAR signaling pathway.

CONCLUSION

These findings provide strong evidence that Curcumae Rhizoma acts as a rich source of phytochemicals and has robust anti-breast cancer properties.

An updated meta-analysis of effects of curcumin on metabolic dysfunction-associated fatty liver disease based on available evidence from Iran and Thailand

Metabolic dysfunction-associated fatty liver disease (MAFLD) is a common cause of chronic liver disease and can progress to nonalcoholic steatohepatitis and cirrhosis. This study aims to summarize the evidence for the effects of curcumin on MAFLD progression. Studies were identified from Medline and Scopus databases until April 2022. Systematic reviews and meta-analyses (SRMA) and randomized controlled trials (RCT) were selected based on pre-specified criteria. Three reviewers independently extracted data and assessed quality of included studies. Of the 427 identified records, 6 SRMAs and 16 RCTs were included in the analysis. Very high overlap was observed among SRMAs with corrected covered area of 21.9%. From an updated meta-analysis, curcumin demonstrated significant improvement in aspartate and alanine aminotransferase with pooled mean difference [95% confidence interval (CI)] of -3.90 (-5.97, -1.82) and -5.61 (-9.37, -1.85) units/L, respectively. Resolution and improvement of hepatic steatosis was higher in curcumin than control group with pooled relative risk (95% CI) of 3.53 (2.01, 6.22) and 3.41 (1.36, 8.56), respectively. Curcumin supplementation also led to lower fasting blood sugar, body mass index, and total cholesterol. Further trials should be conducted to assess the effect of curcumin on liver histology, especially regarding non-invasive hepatic fibrosis and steatosis.

Targeted modulation of gut microbiota by traditional Chinese medicine and natural products for liver disease therapy

The gut microbiota not only constitutes intestinal microenvironment homeostasis and human health but also exerts indispensable roles in the occurrence and progression of multiple liver diseases, including alcohol-related liver disease, nonalcoholic fatty liver disease, autoimmune liver disease and liver cancer. Given the therapeutic status of these diseases, their prevention and early therapy are crucial, and the detailed mechanism of gut microbiota in liver disease urgently needs to be explored. Meanwhile, multiple studies have shown that various traditional Chinese medicines, such as Si Miao Formula, Jiangzhi Granules, Liushen Capsules, Chaihu-Shugan Power, Cassiae Semen and Gynostemma, as well as some natural products, including Costunolide, Coprinus comatus polysaccharide, Antarctic krill oil, Oridonin and Berberine, can repair liver injury, improve fatty liver, regulate liver immunity, and even inhibit liver cancer through multiple targets, links, and pathways. Intriguingly, the aforementioned effects demonstrated by these traditional Chinese medicines and natural products have been shown to be closely related to the gut microbiota, directly driving the strategy of traditional Chinese medicines and natural products to regulate the gut microbiota as one of the breakthroughs in the treatment of liver diseases. Based on this, this review comprehensively summarizes and discusses the characteristics, functions and potential mechanisms of these medicines targeting gut microbiota during liver disease treatment. Research on the potential effects on gut microbiota and the regulatory mechanisms of traditional Chinese medicine and natural products provides novel insights and significant references for developing liver disease treatment strategies. In parallel, such explorations will enhance the comprehension of traditional Chinese medicine and natural products modulating gut microbiota during disease treatment, thus facilitating their clinical investigation and application.
