Camellia oleifera Abel ( C. oleifera ) is a multifunctional oilseed, which is rich in many biological active substances with health-promoting properties, especially polyphenols. Previous research revealed that camellia oil phenolics exhibited anti-inflammatory effect, which originated from seed. Thus, we aimed to explore the components of camellia seed phenolics and its potential mechanism of anti-inflammation. Initially, fractional extraction was processed to prepare the phenolics from camellia seed kernels, and we compare four different fractions of phenolics under the LPS-induced Caco-2/RAW264.7 coculturing model. Results showed that free phenolics (FP) had best effect on alleviating pro-inflammatory cytokines (IL-1β, IL-6, IL-8 and TNF-α) compared to esterified-bound phenolics (EP), glycosylated-bound phenolics (GP) and insoluble-bound phenolics (IP). Furthermore, FP reduced inflammation by suppressing the PI3K/Akt/NF-κB signaling pathway and effectively inhibited LPS-induced intestinal permeability increase, tight junction related proteins loss (ZO-1, claudin-1). Same results obtained, as the transepithelial electrical resistance (TEER) and alkaline phosphatase (AKP) activity of high-dose FP treated group was high than model group. Finally, molecular docking was used for evaluating the anti-inflammatory effect for phenolic monomer. KGRG (kaempferol −3-O-(2-O-glucopyranosyl-6-O-rhamnopyranosyl)-glucopyranoside), KXR (kaempferol 3-O-(2′’-xylopyranosyl)-rutinoside) and leucoside (kaempferol 3-O-sambubioside) show lower binding energy docking with NF-κB, PI3K and Akt protein, indicating better interactions, which might be effective constituents against inflammation. Subsequently, five major polyphenols were obtained to validate the docking results, especially, indicating the best anti-inflammatory activities of KGRG. Overall, this research sheds insights on the therapy of phenolics from C. oleifera seed towards LPS-induced intestinal inflammation model in vitro and its related mechanism.

Pyroptosis induced by oxidative stress is a significant contributor to mental health disorders, including depression (+)-Catechin (CA), a polyphenolic compound prevalent in various food sources, has been substantiated by prior research to exhibit potent antioxidant properties and potential antidepressant effects. Nonetheless, the precise antidepressive mechanisms and effects of CA remain incompletely elucidated. In this study, we employed corticosterone (CORT) and PC12 cells to develop a cellular model of depression, aiming to investigate the protective effects of CA against CORT-induced cellular damage. Our objective was to elucidate the underlying mechanisms of protective action. We utilized transcriptomic analysis to identify differentially expressed genes and employed bioinformatics approaches to predict the potential mechanisms of CA’s protective effects in PC12 cells. These transcriptomic predictions were subsequently validated through western blot analysis. The findings indicated that CA possesses the capacity to mitigate oxidative stress and suppress pyroptosis in PC12 cells via the activation of the PI3K/AKT signaling pathway. This activation subsequently modulates the Nrf2/HO1/NF-κB pathways, thereby providing protection to PC12 cells against damage induced by CORT. Furthermore, we investigated the interaction between CA and the Keap1 protein employing molecular docking and protein thermal shift assays. We propose that CA can activate Nrf2 through two mechanisms to decrease reactive oxygen species (ROS) levels and inhibit pyroptosis: one mechanism involves the activation of the PI3K/AKT signaling pathway, and the other involves direct binding to Keap1, leading to an increase in p-Nrf2.

Multi-drug resistance remains a critical issue in cancer treatment that hinders the effective use of chemotherapeutic drugs. The active components of traditional Chinese medicine have been applied as adjuvants to accentuate the anticancer properties of conventional drugs such as cisplatin. However, their application requires further validation and optimization. This study explored the anticancer activity of β-elemene, a natural component of traditional Chinese medical formulations. The effect of β-elemene on the anticancer properties of cisplatin was evaluated in A549 and NCI-H1650 lung cancer cells. Cell apoptosis, stem-like properties, glucose metabolism, multi-drug resistance, and PI3K/AKT/mTOR activation were assessed via flow cytometry, tumorsphere formation, and western blotting. The target genes of β-elemene were predicted using bioinformatics tools and validated in both cell lines. A xenograft model of lung cancer was established in nude mice to evaluate the combined effects of β-elemene and cisplatin in vivo . We found that β-elemene acted synergistically with cisplatin against non-small cell lung cancer cells by promoting apoptosis and impairing glucose metabolism, multi-drug resistance, and stemness maintenance. These effects were mediated by the inhibition of PI3K/AKT/mTOR activation. Bioinformatics analysis revealed that RB1 and TP53 are common target genes associated with lung cancer and β-elemene. The anti-tumorigenic properties of β-elemene were confirmed in vivo , wherein β-elemene, along with cisplatin, significantly suppressed tumor growth in a mouse xenograft model of non-small cell lung cancer. As such, β-elemene acted as an inhibitor of PI3K/AKT/mTOR signaling and enhanced the anticancer effect of cisplatin by targeting tumor metabolism, chemoresistance, and stem-like behavior. Thus, β-elemene is an effective anticancer adjuvant agent with potential clinical applications.

Cancer immunotherapy has improved the survival rate of patients with malignant tumors. However, the response of solid tumors to immunotherapy is quite limited. Here, we report a pH-responsive nanocomposite for augmented sonodynamic-chemodynamic immunotherapy. This Mn-CaCO 3 -2,2′-azobis[2-(2-imidazolin-2-yl) propane]-dihydrochloride (AIPH) nanosystem, Lipo@MCA, was prepared through a simple two-step reaction. It released sonosensitizer AIPH and Ca 2+ within the acidic tumor microenvironment. AIPH generated alkyl free radicals under ultrasound irradiation, and Mn 2+ produces ·OH through Fenton-like reaction. The Ca 2+ induced calcium overload in tumor cells. This induced mitochondrial dysfunction and promoted tumor cell apoptosis. Lipo@MCA also inhibited the phosphorylation of Akt and PI3K. In vitro experiments indicated that the nanoparticle inhibited tumor cell invasion and migration, and induced tumor cell apoptosis. In vivo experiments demonstrated that Lipo@MCA inhibited tumor growth by promoting cytokine secretion, stimulating dendritic cell maturation, and enhancing T-cell differentiation. In summary, this study paves the way for synergistic inhibition of tumor cell metastasis and immunotherapy in solid tumors through PI3K signaling pathway inhibition.

Background Gerberae Piloselloidis Herba (GPH) exhibits notable efficacy in alleviating allergic asthma. Previous studies in our research have identified a mixture of luteolin, arbutin, and marmesin as effective components of GPH in treating allergic asthma. However, the underlying mechanism remains unclear. This study aims to elucidate the molecular mechanism of these active components. Method Using an ovalbumin (OVA)-induced allergic asthma mouse model, various treatment groups were administered, including GPH, the active component mixture (termed "Mixture") containing luteolin, arbutin, and marmesin, and a positive drug (dexamethasone, DEX). Relevant indices were assessed, including behavioral characteristics, inflammatory cell counts, cytokine levels, histopathological examination of lung tissue, apoptosis, and expression of key proteins such as Caspase-3, Bax, Bcl-2, PI3K, p-PI3K, Akt, and p-Akt. The effect of the Mixture on the PI3K/Akt signaling pathway was further verified using the PI3K inhibitor LY294002. Results The Mixture significantly alleviated asthma symptoms, decreased IgE levels, cytokine levels (IL-4, IL-5, IL-13 and TNF-α), and the number of inflammatory cells in serum or bronchoalveolar lavage fluid (BALF), leading to the alleviation of lung pathological lesions. Additionally, the Mixture reduced the expression of Bax and Caspase-3 while increasing Bcl-2 expression, resulting in mitigated apoptosis in lung tissue. Furthermore, there appeared a decrease in the levels of PI3K and p-PI3K, as well as the ratio of p-Akt to Akt in the Mixture group, indicating the suppression of PI3K and Akt phosphorylation. Interestingly, the effects of the Mixture were comparable to those of GPH, LY294002, or the combination of LY294002 with the Mixture. Conclusion The study confirms that the Mixture containing luteolin, arbutin, and marmesin indeed alleviates allergic asthma induced by OVA in mice by suppressing the PI3K/Akt signaling pathway. These findings highlight the potential of the GPH-derived Mixture as a novel therapeutic for the treatment of allergic asthma.

Background The Qilin pill (QLP) is a traditional Chinese compound prescription comprising 15 herbs that has demonstrated significant therapeutic effects on premature ovarian insufficiency (POI) in recent years. However, a pharmacological evaluation of QLP on ovarian function remains to be conducted, and the key mechanism of QLP treatment on POI is unclear.Methods Premature ovarian insufficiency rats were established by bilateral partial ovariectomy. The model rats were administrated with low (QLP-L), medium (QLP-M) and high (QLP-H) doses of QLP for 4 weeks to evaluate the ovarian function in terms of estrous cycle, hormone level, and follicle count. The mechanism of QLP in the treatment of POI was systematically explored by network pharmacology, and expression levels of the MAPK and PI3K-AKT signaling pathways were verified by Western blotting and molecular docking.Results The rat model of resection-induced POI was successfully established, and QLP could significantly recover the estrous cycle, decrease serum FSH levels, and decelerate follicle depletion after 4 weeks of administration. The optimal dose of QLP in the experiment was preliminarily determined to be 0.9 g/kg. Based on the network pharmacology methods, we constructed the compound-target network and protein protein interaction (PPI) network of QLP for the treatment of POI. The experimental verification of the enrichment analysis showed that QLP inhibited the MAPK and PI3K-AKT signaling pathways, and the key compounds and key targets involved were verified by molecular docking.Conclusion QLP exerted significant therapeutic effects on resection-induced POI rats, and this was achieved by the inhibition of the MAPK and PI3K-AKT signaling pathways. This study is the first to systematically investigate the effects and mechanism of QLP on POI rats, which will provide valuable guidance in clinic.

Tumor cell can be significantly influenced by various chemical groups of the extracellular matrix proteins. However, the underlying molecular mechanisms involved in the interaction between cancer cells and functional groups in the extracellular matrix remain unknown. Using chemically modified surfaces with biological functional groups (CH 3 , NH 2 , OH), it was found that hydrophobic surfaces modified with CH 3 and NH 2 suppressed cell proliferation and induced the number of apoptotic cells. Mitochondrial dysfunction, cytochrome c release, Bax upregulation, cleaved caspase-3 and PARP, and Bcl-2 downregulation indicated that hydrophobic surfaces with CH 3 and NH 2 triggered the activation of intrinsic apoptotic signaling pathway. Cells on the CH 3 - and NH 2 -modified hydrophobic surfaces showed downregulated expression and activation of integrin β1, with a subsequent decrease of focal adhesion kinase (FAK) activity. The RhoA/ROCK/PTEN signaling was then activated to inhibit the phosphorylation of PI3K and AKT, which are essential for cell proliferation. However, pretreatment of MDA-MB-231 cells with SF1670, a PTEN inhibitor, abolished the hydrophobic surface-induced activation of the intrinsic pathway. Taken together, the present results indicate that CH 3 - and NH 2 -modified hydrophobic surfaces induce mitochondria-mediated apoptosis by suppressing the PTEN/PI3K/AKT pathway, but not OH surfaces. These findings are helpful to understand the interaction between extracellular matrix and cancer cells, which might provide new insights into the mechanism potential intervention strategies for tumor prognosis.

Emerging evidence has exhibited an obvious decreased expression of miR-106a-5p in the ectopic endometrial tissue of endometriosis (EMS) patients. Thus far, the pathophysiological function of miR-106a-5p in EMS is unknown. A previous study showed an increased FOXC1 expression in the ectopic endometrial tissue of patients with EMS. Moreover, we found that there was a binding site of miR-106a-5p on the 3ʹUTR of FOXC1 through bioinformatics predictions. Hence, we speculated that miR-106a-5p might affect the development of EMS via targeting FOXC1. We first showed a decreased level of miR-106a-5p and an increased level of FOXC1 mRNA in ectopic endometrial tissues compared with normal tissues. Functionally, we transfected ectopic endometrial stromal cells (ESCs) with miR-106a-5p mimics or NC mimics and indicated an inhibitory role of miR-106a-5p on ESC proliferation, invasion, and migration. Mechanistically, FOXC1 was found to be a target gene of miR-106a-5p. To confirm whether miR-106a-5p exerted an inhibitory activity in ESCs via targeting FOXC1, miR-106a-5p mimic was co-transfected into ESCs with the FOXC1-plasmid or vector. We found that FOXC1 overexpression evidently reversed the results caused by a miR-106a-5p mimic in ESCs. Additionally, our results demonstrated that miR-106a-5p mimic inhibited the expression of p-Akt and p-PI3K. Collectively, these results revealed that miR-106a-5p inhibited the proliferative, migratory, and invasive ability of ESCs via directly binding to FOXC1, likely through the suppression of the PI3K and its downstream signaling pathway, which offered a potential and novel therapeutic strategy for EMS treatment.

Ovotransferrin (OVT), a bioactive protein from egg white, has been demonstrated to exhibit anti-inflammatory efficacy and suppress the progression of ulcerative colitis. Nevertheless, its role in preserving intestinal barrier integrity has not been reported. This study investigated the role of OVT on intestinal barrier dysfunction in DSS-induced ulcerative colitis mice and its underlying mechanisms. OVT significantly attenuated the severity of intestinal barrier injury, reduced inflammatory infiltration, and restored goblet cell density (Model: 5.00 goblet cells/crypt, High: 12.75 goblet cells/crypt) alongside the expression of MUC2 (87.64 %), ZO-1 (83.98 %), and Occludin (74.93 %). Concurrently, OVT decreased intestinal permeability by 84.42 %. Furthermore, OVT downregulated pro-inflammatory cytokines (TNF-α, IL-1β, IL-6), while elevating anti-inflammatory IL-10 levels and restoring redox homeostasis. RNA-seq and Western blot analysis revealed that OVT inhibited the PI3K-Akt/MAPK pathway by decreasing the phosphorylation of p85α (31.73 %), Akt (69.59 %), p38 (25.00 %), and ERK (41.18 %). Metabolomics showed that OVT modulated key metabolites, including L-glutamate, serotonin, and d -fructose-6-phosphate, while decreasing glucose and L-asparagine. These results suggested that OVT regulated immune responses and metabolic pathways, highlighting its therapeutic potential in preserving intestinal barrier integrity.

Drug resistance is a serious problem in cancer therapy. Growing evidence has shown that docosahexaenoic acid has anti-inflammatory and chemopreventive abilities. Studies have shown that autophagy inhibition and ferroptosis are promising therapeutic strategies for overcoming multidrug resistance. This study was aimed to examine whether docosahexaenoic acid (DHA) could reverse docetaxel resistance in prostate cancer cells. Cell survival was examined by MTT and colony formation. Protein expression was determined by Western blot. Reactive oxygen species (ROS) production was measured by flow cytometry. DHA displayed anti-cancer effects on proliferation, colony formation, migration, apoptosis, autophagy and epithelial mesenchymal transition. Glutathione-S-transferase π is an enzyme that plays an important role in drug resistance. DHA inhibited GSTπ protein expression and induced cytoprotective autophagy by regulating the PI3K/AKT signalling pathway in PC3R cells. DHA combined with PI3K inhibitor (LY294002) enhanced apoptosis by alleviating the expression of LC3B, (pro-) caspase- 3 and (uncleaved) PARP. DHA induced ferroptosis by attenuating the expression of glutathione peroxidase 4 (GPX4) and nuclear erythroid 2-related factor 2 (Nrf2). DHA-treated PC3R cells produced ROS. The ROS and cytotoxicity were reversed by treatment with ferrostatin-1. DHA combined with docetaxel inhibited EMT by regulating the expression of E-cadhein and N-cadherin. In summary, DHA reversed drug resistance and induced cytoprotective autophagy and ferroptosis by regulating the PI3K/AKT/Nrf2/GPX4 signalling pathway in PC3R cells. We propose that DHA could be developed as a chemosensitizer and that the PI3K/AKT /Nrf2/GPX4 signalling pathway might be a promising therapeutic target for overcoming cancer drug resistance.

Background Triple-negative breast cancer (TNBC) is a heterogeneous carcinoma characterized by the most aggressive phenotype among all breast cancer subtypes. However, therapeutic options for TNBC patients have limited clinical efficacy due to lack of specific target and efficient targeted therapeutics. Aim To investigate the biological characteristics of a novel estrogen receptor (ER)-α splice variant ER-α30 in breast cancer cells , and its possible role in the anticancer effects of calycosin , a typical phytoestrogen derived from the herbal plant Astragalus membranaceus , against TNBC. This may also provide a better understanding of the inhibitory activity of calycosin on TNBC progression. Methods Breast cancer tissues and para-cancer tissues were collected and analyzed for the expression levels of ER-α30 using immunohistochemistry (IHC), and its expression in two TNBC cell lines (MDA-MB-231 and BT-549) was detected by western blot and qRT-PCR assays. Then the alteration of cell viability , apoptosis , migration, invasion and epithelial-mesenchymal transition (EMT) in response to overexpression or knockdown of ER-α30 was separately determined by CCK-8, Hoechst 33258 , wound healing, transwell and western blot assays in two TNBC cell lines. Next, the anticancer effects of calycosin on MDA-MB-231 cells were evaluated through CCK-8, colony formation, flow cytometry, Hoechst 33258 and western blot assays, along with the role of ER-α30 in these effects and the possible downstream targets of ER-α30. In addition, the in vivo experiments were carried out using MDA-MB-231 xenograft model intraperitoneally treated with calycosin. The volume and weight of xenograft tumor were measured to evaluate the in vivo anticancer activities of calycosin, while the corresponding changes of ER-α30 expression in tumor tissues were detected by IHC. Results It was demonstrated that the novel ER-α splice variant ER-α30 was primarily distributed in the nucleus of TNBC cells. Compared with normal breast tissues, ER-α30 expression was found in significantly higher levels in breast cancer tissues of ER- and progesterone receptor (PR)-negative subtype, so did in TNBC cell lines (MDA-MB-231 and BT-549) when compared to normal breast cell line MCF10A. Moreover, ER-α30 overexpression strikingly enhanced cell viability, migration, invasion and EMT progression and reduced apoptosis in TNBC cells, whereas shRNA-mediated knockdown of ER-α30 revealed the opposite results. Notably, calycosin suppressed the expression of ER-α30 in a dose-dependent manner, accompanied with the inhibition of TNBC growth and metastasis . A similar finding was observed for the xenografts generated from MDA-MB-231 cells. The treatment with calycosin suppressed the tumor growth and decreased ER-α30 expression in tumor tissues. Furthermore, this inhibition by calycosin was more pronounced in ER-α30 knockdown cells. Meanwhile, we found a positive relationship between ER-α30 and the activity of PI3K and AKT, which could also be inactivated by calycosin treatment. Conclusion For the first time, it is demonstrated that the novel estrogen receptor-α splice variant ER-α30 could function as pro-tumorigenic factor in the context of TNBC by participating in cell proliferation , apoptosis, invasion and metastasis, thus it may serve as a potential therapeutic target for TNBC therapy. Calycosin could reduce the activation of ER-α30-mediated PI3K/AKT pathway, thereby inhibited TNBC development and progression, suggesting that calycosin may be a potential therapeutic option for TNBC.

BackgroundHuanglianjiedu decoction (HLJDD) is a classical Traditional Chinese Medicine (TCM) prescription with thousand years of clinical use against various malignancies, including pancreatic adenocarcinoma (PAAD). However, its potential bioactive component and molecular mechanism remains unclear.AimsThis study is to inspect the HLJDD mechanisms of action against PAAD via integrated computational and pharmacochemistry strategy, in vivo and in vitro experiments to validate associated targets and pathways.MethodsA PAAD xenograft model was established by subcutaneous injecting Panc02 cells into C57BL/6 mice. Ultra-high performance liquid chromatography with tandem mass spectrometry (UHPLC-MS/MS) was engaged to determine constituents of HLJDD and assessed for pharmacokinetic scheme using the TCM Systems Pharmacology Platform (TCM-SP). Differentially expressed genes (DEGs) of PAAD was retrieved from the transcriptome dataset GSE43795, followed by recognizing overlapping targets the oncogenes and target genes of PAAD and HLJDD, respectively. Putative signaling pathways of HLJDD in treating PAAD were enriched using KEGG and GO analyses. The anti-PAAD effects of HLJDD was assessed in vivo and in vitro, besides, the potential mechanism was validated using immunoblotting and immunohistochemical assays.ResultsHLJDD significantly suppressed the growth of transplanted PAAD tumors, constrained PAAD progression, and induced apoptosis and S-phase arrest. Seventy-five active components meeting the drug-likeness criteria and 278 target genes of HLJDD were identified. KEGG analysis indicated that the top three enriched pathways were cancer, AGE-RAGE signaling, and IL-17 signaling pathways. Disease enrichment analysis highlighted immune, pharmacological, and cancer-related diseases as the top three categories. A total of 47 potential target genes were identified. Immunoblotting revealed that HLJDD inhibited PI3K and MAPK-related signaling pathways, while immunohistochemical staining confirmed that HLJDD suppressed the expression of phosphorylated MAPK and ERK1/2.ConclusionHLJDD inhibited PAAD in vitro and in vivo via the modulation of multiple mechanisms, including regulation of PI3K/AKT/mTOR and MAPK/ERK1/2 signaling pathways.
