Quan T, Zhang W, Shi Y, Gao T. Melatonin-mediated intestinal microbiota homeostasis improves skin barrier damage involvement of gut-skin axis dysfunction in aging mice. Cell Signal 2025; 133:111859. [PMID: 40349812 DOI: 10.1016/j.cellsig.2025.111859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2025] [Revised: 05/04/2025] [Accepted: 05/08/2025] [Indexed: 05/14/2025]
Abstract
Researches suggested a close connection between the gut microbiome homeostasis and skin health. Melatonin, as a multifunctional molecule, has the potential to regulate intestinal homeostasis and skin function. The study further explored the potential mechanism of melatonin in ameliorating skin barrier damage from the perspective of the association between intestinal microbiota and gut-skin axis in aging mice. We established a natural aging-induced skin barrier damage mouse model with or without melatonin supplementation and fecal microbiota transplantation (FMT) to clarify the crucial role of intestinal microbiota-mediated gut-skin axis in melatonin improving skin barrier damage. Furthermore, lipopolysaccharide (LPS)-treated mice and human keratinocytes cells (HaCaT) explored the modulation mechanism of melatonin. Our results suggested that aging induced skin barrier damage, including skin microbiota disorder and epidermal barrier structure disruption, and intestinal dysbiosis. Similarly, FMT from aging mice and LPS treatment rebuild the aging-like skin barrier damage. Whereas, melatonin or resatorvid (TAK242, the antagonist of LPS) supplementation restored all consequence in aging and LPS-treated mice. In vitro, melatonin restored LPS-induced skin barrier proteins deficiency in HaCaT via decreasing the expression level of TLR4 and MyD88 and increasing the content of p-ERK, p-GSK-3β and β-catenin proteins, while the improving effects was mimicked by pretreatment with a TLR4 antagonist but were blocked by GSK-3β agonists. Our study revealed that melatonin-mediated intestinal microbiota homeostasis suppresses LPS escape to restore the skin barrier function, including skin dysbiosis and epidermal structural disruption via LPS/TLR4/MyD88/ERK/GSK-3β/β-catenin loop, further improving skin aging in mice.

Abstract
Design and development of efficient drug delivery technologies that impart site-specificity is the need of the hour for the effective treatment of lung cancer. The emergence of materials science and nanotechnology partially helped drug delivery scientists to achieve this objective. Various stimuli-responsive materials that undergo degradation at the pathological tumor microenvironment (TME) have been developed and explored for drug delivery applications using nanotechnological approaches. Nanoparticles (NPs), owing to their small size and high surface area to volume ratio, demonstrated enhanced cellular internalization, permeation, and retention at the tumor site. Such passive accumulation of stimuli-responsive materials helped to achieve spatiotemporally controlled and targeted drug delivery within the tumors. In this review, we discussed various stimuli-physical (interstitial pressure, temperature, and stiffness), chemical (pH, hypoxia, oxidative stress, and redox state), and biological (receptor expression, efflux transporters, immune cells, and their receptors or ligands)-that are characteristic to the TME. We mentioned an array of biomaterials-based nanoparticulate delivery systems that respond to these stimuli and control drug release at the TME. Further, we discussed nanoparticle-based combinatorial drug delivery strategies. Finally, we presented our perspectives on challenges related to scale-up, clinical translation, and regulatory approvals.

Abstract
Biochemical analysis of human normal bronchial cells (BEpiC) and human cancer lung cells (A549) has been performed by using Raman spectroscopy and Raman imaging. Our approach provides a biochemical compositional mapping of the main cell components: nucleus, mitochondria, lipid droplets, endoplasmic reticulum, cytoplasm and cell membrane. We proved that Raman spectroscopy and Raman imaging can distinguish successfully BEpiC and A549 cells. In this study, we have focused on the role of mannose in cancer development. It has been shown that changes in the concentration of mannose can regulate some metabolic processes in cells. Presented results suggest lipids and proteins can be considered as Raman biomarkers during lung cancer progression. Analysis obtained for bands 1444 cm-1, and 2854 cm-1 characteristic for lipids and derivatives proved that the addition of mannose reduced levels of these compounds. Results obtained for protein compounds based on bands 858 cm-1, 1004 cm-1 and 1584 cm-1 proved that the addition of mannose increases the values of protein in BEpiC cells and blocks protein glycolisation in A549 cells. Noticing Raman spectral changes in BEpiC and A549 cells supplemented with mannose can help to understand the mechanism of sugar metabolism during cancer development and could play in the future an important role in clinical treatment.

[PMID: 37845392 DOI: 10.1038/s41388-023-02856-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 09/22/2023] [Accepted: 09/29/2023] [Indexed: 10/18/2023]
Abstract
In non-small cell lung cancer (NSCLC), the overexpression or abnormal activation of epidermal growth factor receptor (EGFR) is associated with tumor progression and drug resistance. EGFR tyrosine kinase inhibitors (TKIs) are currently the first-line treatment of NSCLC. However, patients inevitably acquired EGFR TKIs resistance mutations, which led to disease progression, so it is urgent to find new treatment. Here, we report that D-mannose up-regulates lysosomal activity by enhancing TFE3-mediated lysosomal biogenesis, thereby increasing the degradation of EGFR and significantly down-regulating its protein level. Therefore, D-mannose significantly inhibited the proliferation, migration and invasion of wild-type EGFR (WT-EGFR) and EGFR mutant cells (E746-A750 deletion, L858R and T790M mutations) in vitro. Oral administration of D-mannose strongly inhibited tumor growth in mice, showing similar effects with osimertinib. Taken together, these data suggest that D-mannose may represent a new strategy for clinical treatment of NSCLC.

Abstract
Studies examining the regulatory roles and clinical applications of monosaccharides other than glucose in cancer have been neglected. Mannose, a common type of monosaccharide found in human body fluids and tissues, primarily functions in protein glycosylation rather than carbohydrate metabolism. Recent research has demonstrated direct anticancer effects of mannose in vitro and in vivo. Simply supplementing cell culture medium or drinking water with mannose achieved these effects. Moreover, mannose enhances the effectiveness of current cancer treatments including chemotherapy, radiotherapy, targeted therapy, and immune therapy. Besides the advancements in basic research on the anticancer effects of mannose, recent studies have reported its application as a biomarker for cancer or in the delivery of anticancer drugs using mannose-modified drug delivery systems. This review discusses the progress made in understanding the regulatory roles of mannose in cancer progression, the mechanisms underlying its anticancer effects, and its current application in cancer diagnosis and treatment.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is a highly malignant cancer with limited treatment options. Mannose, a common monosaccharide taken up by cells through the same transporters as glucose, has been shown to induce growth retardation and enhance cell death in response to chemotherapy in several cancers, including PDAC. However, the molecular targets and mechanisms underlying mannose's action against PDAC are not well understood. In this study, we used an integrative approach of network pharmacology, bioinformatics analysis, and experimental verification to investigate the pharmacological targets and mechanisms of mannose against PDAC. Our results showed that the protein Src is a key target of mannose in PDAC. Additionally, computational analysis revealed that mannose is a highly soluble compound that meets Lipinski's rule of five and that the expression of its target molecules is correlated with survival rates and prognosis in PDAC patients. Finally, we validated our findings through in vitro and in vivo experiments. In conclusion, our study provides evidence that mannose plays a critical role in inhibiting PDAC growth by targeting Src, suggesting that it may be a promising therapeutic candidate for PDAC.

ANP32A Knockdown Attenuates the Malignant Biological Behavior of Colorectal Cancer Cells by Suppressing Epithelial-mesenchymal Transition and ERK Activation. J Cancer 2023; 14:2759-2770.

Abstract
Acidic leucine rich nuclear phosphoprotein-32A (ANP32A) protein has a variety of functions, such as regulating cell differentiation, influencing cell apoptosis and cell cycle progression. Our previous study demonstrated that high expression of ANP32A was found in the tumor tissues of colorectal cancer (CRC) patients and was positively associated with tumor grading. However, the function and underlying mechanisms of ANP32A in CRC metastasis have not been fully explored. In this study, we found that ANP32A knockdown significantly attenuated the migration and invasion, and epithelial-mesenchymal transition (EMT) in cells. Further mechanistic studies revealed that ANP32A knockdown inhibited the expression of β-catenin and phosphorylated-ERK. The immunofluorescent staining experiment has revealed that ANP32A was expressed in the cell membrane, cytosol and nucleus, and its expression was positively associated with β-catenin expression levels. Moreover, the ability of cell migration and invasion was inhibited, the expression of E-cadherin was enhanced following ANP32A knockdown, and these affects were abolished by an ERK activator PMA, enhanced by an ERK inhibitor PD98059. Moreover, our animal experiment also demonstrated that silenced ANP32A inhibited CRC cell growth, multi-organ metastasis, ERK activation and EMT progression in vivo. Collectively, these findings demonstrated that ANP32A promotes CRC progression and that may be a promising target for the anti-metastasis treatment of CRC.

Abstract
As a natural sugar, mannose is a type of hexose that is abundant in many different types of fruits. Since mannose is rarely used for glycolysis in mammals, studies on the role of mannose have not attracted much attention. Glycosylation of specific proteins was thought to be the major function of mannose. Surprisingly, during the past few years, mannose was found to be effective in promoting immune tolerance and suppressing inflammatory diseases related to autoimmunity and allergy. Moreover importantly, mannose was also found to be efficient in suppressing tumors by suppressing glycolysis and enhancing chemotherapeutic agents. In this review, we summarize the recent studies of mannose on antitumor properties and anti-inflammatory characteristics. We emphasize that mannose could play a beneficial role in the treatment of a variety of diseases, including cancers and inflammatory diseases, and could be a novel therapeutic strategy that deserves continued evaluation.

Abstract
Background Various natural compounds are effective in cancer prevention and treatment with fewer side effects than conventional radiotherapy and chemotherapy. Considering the uncertainty of the antitumor mechanism of Echinacoside (Ech) and the fact that no study on Ech against non-small cell lung cancer (NSCLC) has been explored previously, this study inquired into the anti-NSCLC effect of Ech and explored its potential mechanisms. Methods The IC50 to Ech of the NSCLC cells was calculated based on a series of cell viability assays. Different concentrations of Ech were used to treat the cells; the proliferation activity of the cells was evaluated using EdU staining. Mitochondrial membrane potential was detected by JC-1 staining. Levels of cytokines IL-1β and IL-18 were measured by ELISA. GSH and MDA levels were measured by microplate reader. Expression of cytochrome c, NLRP3, caspase-1, IL-1β, c-Myc, c-Fos, and Raf/MEK/ERK pathway proteins was evaluated by western blot. Meanwhile, we used xenograft, immunohistochemical staining, and H&E staining to evaluate the pharmacological effects of Ech in mice in vivo. Results ECH inhibited the proliferation of NSCLC cells. Ech increased the expression of pyroptosis-related proteins. Besides, Ech perturbed the mitochondrial membrane potential with the release of mitochondrial cytochrome c, accompanied by increased oxidative stress. Ech inhibited the phosphorylation levels of Raf/MEK/ERK signaling pathway and subsequently reduced c-myc and c-fos protein expression. In addition, Ech effectively restrained the growth of tumors in vivo. Conclusions Ech inhibited the Raf/MEK/ERK signaling. Impaired mitochondria activated inflammasome, which in turn led to the pyroptosis of NSCLC cells. These findings can provide some ideas on how to use pyroptosis to treat NSCLC.

Abstract
Although initially discovered and extensively studied for its role in inflammation, Annexin A1 (ANXA1) has been reported to be closely related to cancer in recent years, and its role in cancer is specific to tumor types and tissues. In the present study, we identified ANXA1 as an interaction partner of glycogen synthase kinase 3 beta (GSK3β), a multi-functional serine/threonine kinase tightly associated with cell fate determination and cancer, and assessed the functional significance of GSK3β-ANXA1 interaction in the metastasis of non-small cell lung cancer (NSCLC). We confirmed the interaction between GSK3β and ANXA1 in vitro and in H1299 and A549 cells by Glutathione-S-transferase (GST) pull-down assay and co-immunoprecipitation. We found that ANXA1 negatively regulated the phosphorylation of GSK3β and inhibited the epithelial-mesenchymal transformation (EMT) process and migration and invasion of NSCLC cells. By functional rescue assay, we confirmed that ANXA1 inhibited EMT through the regulation of GSK3β activity and thereby inhibited the migration and invasion of NSCLC cells. Our study sheds light on the function of ANXA1 and GSK3β and provides new elements for the understanding of NSCLC pathogenesis.
