MEN1 is a regulator of alternative splicing and prevents R-loop-induced genome instability through suppression of RNA polymerase II elongation.

The fidelity of alternative splicing (AS) patterns is essential for growth development and cell fate determination. However, the scope of the molecular switches that regulate AS remains largely unexplored. Here we show that MEN1 is a previously unknown splicing regulatory factor. MEN1 deletion resulted in reprogramming of AS patterns in mouse lung tissue and human lung cancer cells, suggesting that MEN1 has a general function in regulating alternative precursor mRNA splicing. MEN1 altered exon skipping and the abundance of mRNA splicing isoforms of certain genes with suboptimal splice sites. Chromatin immunoprecipitation and chromosome walking assays revealed that MEN1 favored the accumulation of RNA polymerase II (Pol II) in regions encoding variant exons. Our data suggest that MEN1 regulates AS by slowing the Pol II elongation rate and that defects in these processes trigger R-loop formation, DNA damage accumulation and genome instability. Furthermore, we identified 28 MEN1-regulated exon-skipping events in lung cancer cells that were closely correlated with survival in patients with lung adenocarcinoma, and MEN1 deficiency sensitized lung cancer cells to splicing inhibitors. Collectively, these findings led to the identification of a novel biological role for menin in maintaining AS homeostasis and link this role to the regulation of cancer cell behavior.

Targeting inflammatory macrophages rebuilds therapeutic efficacy of DOT1L inhibition in hepatocellular carcinoma.

Epigenetic reprogramming is a promising therapeutic strategy for aggressive cancers, but its limitations in vivo remain unclear. Here, we showed, in detailed studies of data regarding 410 patients with human hepatocellular carcinoma (HCC), that increased histone methyltransferase DOT1L triggered epithelial-mesenchymal transition-mediated metastasis and served as a therapeutic target for human HCC. Unexpectedly, although targeting DOT1L in vitro abrogated the invasive potential of hepatoma cells, abrogation of DOT1L signals hardly affected the metastasis of hepatoma in vivo. Macrophages, which constitute the major cellular component of the stroma, abrogated the anti-metastatic effect of DOT1L targeting. Mechanistically, NF-κB signal elicited by macrophage inflammatory response operated via a non-epigenetic machinery to eliminate the therapeutic efficacy of DOT1L targeting. Importantly, therapeutic strategy combining DOT1L-targeted therapy with macrophage depletion or NF-κB inhibition in vivo effectively and successfully elicited cancer regression. Moreover, we found that the densities of macrophages in HCC determined malignant cell DOT1L-associated clinical outcome of the patients. Our results provide insight into the crosstalk between epigenetic reprogramming and cancer microenvironments and suggest that strategies to influence the functional activities of inflammatory cells may benefit epigenetic reprogramming therapy.

Exploring the Biomedical Potential of Terpenoid Alkaloids: Sources, Structures, and Activities.

Terpenoid alkaloids are recognized as a class of compounds with limited numbers but potent biological activities, primarily derived from plants, with a minor proportion originating from animals and microorganisms. These alkaloids are synthesized from the same prenyl unit that forms the terpene skeleton, with the nitrogen atom introduced through ß-aminoethanol, ethylamine, or methylamine, leading to a range of complex and diverse structures. Based on their skeleton type, they can be categorized into monoterpenes, sesquiterpenes, diterpenes, and triterpene alkaloids. To date, 289 natural terpenoid alkaloids, excluding triterpene alkaloids, have been identified in studies published between 2019 and 2024. These compounds demonstrate a spectrum of biological activities, including anti-inflammatory, antitumor, antibacterial, analgesic, and cardioprotective effects, making them promising candidates for further development. This review provides an overview of the sources, chemical structures, and biological activities of natural terpenoid alkaloids, serving as a reference for future research and applications in this area.

Disability weight measurement for the severity of different diseases in Wuhan, China.

BACKGROUND: Measurement of the Chinese burden of disease with disability-adjusted life-years (DALYs) requires disability weight (DW) that quantify health losses for all non-fatal consequences of disease and injury. The Global Burden of Disease (GBD) 2013 DW study indicates that it is limited by lack of geographic variation in DW data and by the current measurement methodology. We aim to estimate DW for a set of health states from major diseases in the Wuhan population. METHODS: We conducted the DW measurement study for 206 health states through a household survey with computer-assisted face-to-face interviews and a web-based survey. Based on GBD 2013 DW study, paired comparison (PC) and Population health equivalence (PHE) method was used and different PC/PHE questions were randomly assigned to each respondent. In statistical analysis, the PC data was analyzed by probit regression. The probit regression results will be anchored by results from the PHE data analyzed by interval regression on the DW scale units between 0 (no loss of health) and 1 (loss equivalent to death). RESULTS: A total of 2610 and 3140 individuals were included in the household and web-based survey, respectively. The results from the total pooled data showed health state "mild anemia" (DW = 0.005, 95% UI 0.000-0.027) or "allergic rhinitis (hay fever)" (0.005, 95% UI 0.000-0.029) had the lowest DW and "heroin and other opioid dependence, severe" had the highest DW (0.699, 95% UI 0.579-0.827). A high correlation coefficient (Pearson's r = 0.876; P < 0.001) for DWs of same health states was observed between Wuhan's survey and GBD 2013 DW survey. Health states referred to mental symptom, fatigue, and the residual category of other physical symptoms were statistically significantly associated with a lower Wuhan's DWs than the GBD's DWs. Health states with disfigurement and substance use symptom had a higher DW in Wuhan population than the GBD 2013 study. CONCLUSIONS: This set of DWs could be used to calculate local diseases burden for health policy-decision in Wuhan population. The DW differences between the GBD's survey and Wuhan's survey suggest that there might be some contextual or culture factors influencing assessment on the severity of diseases.

PD-L1 blockade liberates intrinsic antitumourigenic properties of glycolytic macrophages in hepatocellular carcinoma.

OBJECTIVE: Patients with increased PD-L1+ host cells in tumours are more potent to benefit from antiprogrammed death-1/programmed death ligand-1 (PD-L1) treatment, but the underlying mechanism is still unclear. We aim to elucidate the nature, regulation and functional relevance of PD-L1+ host cells in hepatocellular carcinoma (HCC). DESIGN: A total of untreated 184 HCC patients was enrolled randomly. C57BL/6 mice are given injection of Hepa1-6 cells to form autologous hepatoma. ELISpot, flow cytometry and real-time PCR are applied to analyse the phenotypic characteristics of PD-L1+ cells isolated directly from HCC specimens paired with blood samples or generated from ex vivo and in vitro culture systems. Immunofluorescence and immunohistochemistry are performed to detect the presence of immune cells on paraffin-embedded and formalin-fixed samples. The underlying regulatory mechanisms of metabolic switching are assessed by both in vitro and in vivo studies. RESULTS: We demonstrate that PD-L1+ host macrophages, which constructively represent the major cellular source of PD-L1 in HCC tumours, display an HLA-DRhighCD86high glycolytic phenotype, significantly produce antitumourigenic IL-12p70 and are polarised by intrinsic glycolytic metabolism. Mechanistically, a key glycolytic enzyme PKM2 triggered by hepatoma cell derived fibronectin 1, via a HIF-1α-dependent manner, concurrently controls the antitumourigenic properties and inflammation-mediated PD-L1 expression in glycolytic macrophages. Importantly, although increased PKM2+ glycolytic macrophages predict poor prognosis of patients, blocking PD-L1 on these cells eliminates PD-L1-dominant immunosuppression and liberates intrinsic antitumourigenic properties. CONCLUSIONS: Selectively modulating the 'context' of glycolytic macrophages in HCC tumours might restore their antitumourigenic properties and provide a precise strategy for anticancer therapy.

TRIM33 Modulates Inflammation and Airway Remodeling of PDGF-BB-Induced Airway Smooth-Muscle Cells by the Wnt/ß-Catenin Pathway.

Asthma is a chronic airway disease involving airway inflammation and remodeling. Studies showed that tripartite motif-containing protein 33 (TRIM33) regulated natural immunity, inflammation, and pulmonary fibrosis. However, the role and regulatory mechanism of TRIM33 in children's asthma are unclear. In this study, the TRIM33 expressions in serum samples and platelet-derived growth factor BB (PDGF-BB)-induced airway smooth-muscle cells (ASMCs) were evaluated. A gain-of-function experiment was performed, and cell proliferation and migration were detected using CCK-8 and wound healing assays. Besides, the protein levels of EMT biomarkers and airway-remodeling markers were determined by Western blot assay. ELISA analyzed the contents of IL-1ß, IL-6, and TNF-α in the supernatant. The modulation of Smad4 expression and subsequent activation of Wnt/ß-catenin by TRIM33 were also assessed. We found that TRIM33 was downregulated in the serum from children who were asthma patients and PDGF-BB-induced ASMCs. TRIM33 overexpression showed decrease of PDGF-BB-induced ASMC proliferation and migration. Moreover, the augment of TRIM33 reduced the PDGF-BB-induced cell EMT and airway-remodeling marker levels and suppressed the secretions of inflammatory cytokines in PDGF-BB-induced ASMCs. Additionally, TRIM33 overexpression inhibited activation of Wnt/ß-catenin via reducing Smad4 expression to regulate asthma inflammation and airway remodeling. All in all, our study revealed that TRIM33 expression was downregulated in children who were asthma patients and PDGF-BB-induced ASMCs. TRIM33 modulated PDGF-BB-induced inflammation and airway remodeling of ASMCs by the Wnt/ß-catenin pathway via regulating Smad4, which may provide a new treatment direction for asthma.

LincRNA RMRP Regulates Phenylephrine-induced Cardiomyocyte Hypertrophy by Means of Targeting miR-1.

ABSTRACT: Cardiac hypertrophy is a feature of hypertrophic cardiomyopathy (HCM), which could lead to heart failure and other cardiovascular diseases. Cardiomyocyte hypertrophy (CH) is the primary characteristic of cardiac hypertrophy. Long noncoding RNA (lncRNA, lincRNA) plays an important role in CH. In this study, the expression of linc-RMRP and its correlation with cardiac hypertrophy were analyzed in cardiac tissues of patients with HCM. Real-time qPCR and western blotting measured the expressions of lincf-RMRP, miR-1, and hypertrophic marker genes. RNA pulldown and luciferase reporter gene assays were performed to validate the combination between linc-RMRP and miR-1. We confirmed that Linc-RMRP was upregulated in both cardiac hypertrophy tissues and phenylephrine (PE)-induced CH cells, and the cells presented hypertrophic features, enlarged cell surface area and volume, elevated total protein contents, and increased expressions of ANP, BNP, ß-MHC, and activated p70S6K and 4EBP1. Bioinformatic analysis found that linc-RMRP directly bonds to miR-1. RNA pulldown, mutation, and luciferase reporter gene assays verified this combination. Silencing linc-RMRP significantly attenuated hypertrophic responses induced by PE while the expression of miR-1 was released. However, the transfection of miR-1 inhibitor reversed the effects of linc-RMRP knockdown exerted on PE-treated cardiomyocytes. In summary, our study identified the modulatory role linc-RMRP played in regulating PE-induced CH by means of binding miR-1, and this might provide a new target for cardiac hypertrophy therapy.

An iron-mediated highly selective C-H sulfonylmethylation of aniline derivatives with p-toluenesulfonylmethyl isocyanide in a mixture solvent of H2O and PEG400 under an Ar atmosphere has been realized. This transformation proceeds with operational convenience, use of earth-abundant metal catalyst and nontoxic media, broad substrate scope, and good functional group tolerance. The current methodology could be applied to the regioselective C-H sulfonylmethylation of indolines, tetrahydroquinolines, and tertiary anilines.

Plasma Cell Polarization to the Immunoglobulin G Phenotype in Hepatocellular Carcinomas Involves Epigenetic Alterations and Promotes Hepatoma Progression in Mice.

BACKGROUND & AIMS: Little is known about the composition and generation of plasma cell subsets in patients with hepatocellular carcinoma (HCC) and how these associate with outcomes. We investigated whether, or how, plasma cells differentiate and function in patients with HCC and mice with liver tumors. METHODS: We analyzed subset composition and distribution of plasma cells in HCC samples from 342 patients who underwent curative resection at the Cancer Center of Sun Yat-sen University in China; samples of non-tumor liver tissue were used as controls. We associated plasma cell profiles with patient outcomes. Tissue-derived leukocytes were analyzed by flow cytometry and real-time polymerase chain reaction. The ability of macrophages to regulate plasma cell differentiation was determined in ex vivo cultures of cells from human HCC tissues. C57BL/6 and BALB/c mice were given injections of Hepa1-6 cells, which formed hepatomas, or H22 cells, which formed ascitic hepatomas. Gene expression patterns were analyzed in human HCC, mouse hepatoma, and non-tumor tissues by real-time polymerase chain reaction. Mice with hepatomas were given injections of GSK126 (an inhibitor of histone H3 lysine 27 methyltransferase [EZH2]) and 5-AZA-dC (an inhibitor of DNA methyltransferases); tumor tissues were analyzed by immunofluorescence and immunohistochemistry for the presence of immune cells and cytokines. RESULTS: B cells isolated from HCCs had somatic hypermutations and class-switch recombinations to the IgG phenotype that were not observed in non-tumor tissues. Increased level of plasma cells correlated with poor outcomes of patients. Activated CD4+ T cells from HCCs stimulated C-X-C motif chemokine 10 (CXCL10) production by macrophages. CXCL10 bound CXC chemokine receptor 3 on B cells and signaled via extracellular signal-regulated kinase to cause them to become IgG-producing plasma cells. IgG activated Fc receptors on macrophages and induced them to produce interleukin 6, interleukin 10, and C-C motif chemokine ligand 20 (CCL20). In mice with hepatomas, depletion of B cells prevented generation of these macrophage, increased the anti-tumor T cell response, and reduced growth of hepatomas. However, these effects were lost after injection of CXC chemokine receptor 3-positive plasma cells. Human HCC and mouse hepatoma tissues had increased expression of DNA methyltransferase 1 and EZH2 compared with non-tumor tissues. Injection of mice with GSK126 and 5-AZA-dC induced expression of CXCL10 by tumor cells and caused plasma cell polarization, suppression of the anti-tumor T cell response, and hepatoma growth. CONCLUSIONS: Human HCC tissues contain B cells with class-switch recombinations to the IgG phenotype. Activated CD4+ T cells from HCCs stimulate CXCL10 production by macrophages; CXCL10 binds CXC chemokine receptor 3 on B cells and causes them to become IgG-producing plasma cells. IgG activates Fc receptor in macrophages to produce cytokines that reduce the anti-tumor immune response. In mice with hepatomas, depletion of B cells prevented generation of these macrophages, increased the anti-tumor T cell response, and reduced growth of hepatomas. This pathway involves increased expression of DNA methyltransferase 1 and EZH2 by HCC and hepatoma cells.

Rh(III)-Catalyzed C-H Cyanation of 2H-Indazole with N-Cyano-N-phenyl-p-toluenesulfonamide.

A Rh(III)-catalyzed direct cyanation of 2H-indazoles with N-cyano-N-phenyl-p-toluenesulfonamide has been realized via a chelation-assisted strategy. The methodology enables regioselective access to various ortho-cyanated phenylindazoles in good yields with a broad substrate scope and good functional group compatibility. The obtained cyanated indazoles could further be converted into other value-added chemicals. Importantly, the current protocol is featured with several characteristics, including a novel cyanating agent, good regioselectivity, and operational convenience.

A series of novel 5-fluorine-benzimidazole-4-carboxamide analogs were designed and synthesized. All target compounds were evaluated for their PARP-1 inhibitory activity. Compounds possessed high intrinsic PARP-1 inhibitory potency have been evaluated in vitro cellular assays to measure the potentiation effect of cytotoxic agents against cancer cell line. These efforts led to the identification of compound 10f, which displayed strong inhibition against the PARP-1 enzyme with an IC50 of 43.7nM, excellent cell inhibitory activity in HCT116 cells (IC50=7.4µM) and potentiation of temozolomide cytotoxicity in cancer cell line A549 (PF50=1.6).

Effect of jiaweiwumel decoction on regulatory T cells and interleukin-10 in a rat model of ulcerative colitis.

OBJECTIVE: To investigate the effect of a decoction made from the Traditional Chinese Medicine wumei pill, on regulatory T cells and interleukin-10 (IL-10) in a rat model of ulcerative colitis induced by 2,4,6-trinitrobenzene sulfonic acid (TNBS). METHODS: Rat ulcerative colitis was induced with TNBS. All modeled rats were randomly divided into six groups: normal control group; model group; sulfasalazine suppositories treatment group; and high, moderate, and low dosage of jiaweiwumei decoction groups (12 rats each). Colon injury index was evaluated after 14 days. After peripheral blood lymphocyte separation, CD4+ T cells and CD4+/CD25+ T cell percentage was detected by flow cytometry. The content of IL-10 in serum and intestinal mucosa tissue was detected by sandwich enzyme-linked immunosorbent assay. RESULTS: Colon injury indices in the decoction groups were effectively reduced, compared with the model group (P < 0.05). Compared with that of the control group, the CD4+/CD25+ to CD4+ T lymphocyte ratio of the model group was significantly lower, while the decoction treatment improved the CD4 +/CD25 + to CD4 + T lymphocyte ratio (P < 0.05). The serum and mucosal IL-10 content of the model group was significantly lower (P < 0.05) than that in the control group, while the decoction group had significantly higher serum and intestinal mucosal IL-10 content than that in the model group (P < 0.05). The regulatory T cell content was negatively correlated with the colonic injury index (r = 0.68, P < 0.05), and positively correlated with the content of serum IL-10 (r= 0.87, P < 0.05) and intestinal mucosal IL-10 (r= 0.79, P < 0.05). CONCLUSION: Jiaweiwumei decoction had significant effects on regulatory T cells and IL-10 in rats with TNBS-induced ulcerative colitis.

Electrolyte disorders induced by six multikinase inhibitors therapy for renal cell carcinoma: a large-scale pharmacovigilance analysis.

To provide evidence for optimization of multi-kinase inhibitors (MKIs) use in the clinic, we use the public database to describe and evaluate electrolyte disorders (EDs) related to various MKIs treated for renal cell carcinoma. We analyzed spontaneous reports submitted to the Food and Drug Administration Adverse Events Reporting System (FAERS) in an observational and retrospective manner. Selecting electrolyte disorders' adverse events to multikinase inhibitors (axitinib, cabozantinib, lenvatinib, pazopanib, sunitinib, and sorafenib). We used Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), Bayesian Confidence Propagation Neural Network (BCPNN), and multi-item gamma Poisson shrinker (MGPS) algorithms to analyze suspected adverse reactions of electrolyte disorders induced by MKIs (which were treated for renal cell carcinoma) between January 2004 and December 2022. As of December 2022, 2772 MKIs (which were treated for renal cell carcinoma) ICSRs were related to electrolyte disorders AEs. In general, there were more AEs cases in males, except lenvatinib and 71.8% of the cases were submitted from North America. ICSRs in this study, the age group most frequently affected by electrolyte disorders AEs was individuals aged 45-64 years for axitinib, cabozantinib, pazopanib, and sunitinib, whereas electrolyte disorders AEs were more common in older patients (65-74 years) for sorafenib and lenvatinib. For all EDs documented in ICSRs (excluding missing data), the most common adverse outcome was hospitalization(1429/2674, 53.4%), and the most serious outcome was death/life-threat(281/2674, 10.5%). The prevalence of mortality was highest for sunitinib-related EDs (145/616, 23.5%), excluding missing data (n = 68), followed by cabozantinib-related EDs (20/237, 8.4%), excluding missing data (n = 1). The distribution of time-to-onset of Each drug-related ICSRs was not all the same, and the difference was statistically significant (P = 0.001). With the criteria of ROR, the six MKIs were all significantly associated with electrolyte disorders AEs, the strongest association was the association between cabozantinib and hypermagnesaemia. MKIs have been reported to have significant electrolyte disorders AEs. Patients and physicians need to recognize and monitor these potentially fatal adverse events.

A series of novel cyclic amine-substituted imidazo[4,5-c]pyridinecarboxamide analogs were designed and synthesized. All the target compounds were evaluated for their PARP inhibition activity, and the result indicated that most of the compounds possessed inhibitory effect on PARP at the concentration of 1µM, among which compound 8d (IC50=0.528 µM) was selected for evaluating the antitumor effect in vivo. The result showed the antitumor efficacy of the compound 8d and cisplatin combination group in a mouse A549 model is similar with that of the ABT-888 and cisplatin combination group.

Moderating effects of humanistic care and socioeconomic status on the relationship among pain intensity, psychological factors, and psychological function in adults with cancer pain from a province of China: A cross-sectional study.

Objective: The objective of this study is to explore whether humanistic care practiced by clinical pharmacists and socioeconomic status moderate the associations among pain intensity, psychological factors (catastrophizing and resilience), and psychological function (depression and anxiety) in cancer patients with low levels of education and income in the Shanxi province in the Northwest of China. Methods: Our sample comprised 123 adult inpatients with cancer pain. Demographic variables were obtained from the Hospital Information System of The Second Hospital of Shanxi Medical University. Pain intensity, psychological factors, and psychological functions were evaluated with four scales, and humanistic care was practiced with a part of the patients by clinical pharmacists. First, univariate analyses were conducted, followed by moderating effect models. Results: The incidence of depression and anxiety in patients with cancer pain in our sample were 48.78 and 41.46%, respectively. Low levels of psychological resilience (63.37, SD 21.74) were in this study. Pain intensity was significantly associated with humanistic care and anxiety. Humanistic care practiced by clinical pharmacists moderated not only the association between resilience and pain intensity but also the association between pain intensity and anxiety. Education levels moderated the relationship between pain intensity and the psychological factors of catastrophizing and resilience. Income levels moderated the association between resilience and anxiety. Conclusion: Humanistic care is essential in moderating the association among pain intensity, psychological factors, and psychological functions in Chinese cancer patients, especially those from lower-level counties and rural areas. Furthermore, socioeconomic statuses, such as education level and income, cannot easily change quickly. Still, proper humanistic care can relieve pain more effectively, reminding us that medical staff should implement effective personalized interventions to reduce patients' pain intensity.

Psychiatric adverse reactions to non-selective RET multi-kinase inhibitors: a large-scale pharmacovigilance analysis.

Objective: The development of non-selective multi-kinase inhibitors (MKIs) has improved the. survival outcomes of patients with cancers. Psychiatric disorders represent an MKIs related AE of particular concern, as they are often ignored and may harm the patient's personal and social functioning. Therefore, we use the public database to describe and evaluate psychiatric adverse events related to various non-selective RET MKIs. Provide evidence for optimizing drug administration in the clinic. Methods: We analyzed spontaneous reports submitted to the Food and Drug Administration Adverse Events Reporting System FDA Adverse Event Reporting System in an observational and retrospective manner. Selecting psychiatric AEs to non-selective RET multikinase inhibitors (sorafenib, lenvatinib, vandetanib, cabozantinib, and sunitinib). We used Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), Bayesian Confidence Propagation Neural Network (BCPNN), and multi-item gamma Poisson shrinker (MGPS) algorithms to analyze suspected adverse reactions of psychiatric related induced by non-selective RET MKIs between January 2004 and September 2022. Results: As of September 2022, 1,108 non-selective RET MKIs ICSRs were related to psychiatric AEs. 706 were ADR ICSRs, and 402 were non-ADR ICSRs. There were more ADR cases in males (69.5%), and 71.8% of the cases were submitted from North America. The age group most frequently affected by psychiatric ADRs was individuals aged 50-64 years for sorafenib, whereas 65-74 years for sunitinib, cabozantinib, and lenvatinib. In all psychiatric ADRs ICSRs, excluding missing data (n = 329), the most common adverse outcome was hospitalization (260/377, 69.0%), and the most serious was death (100/377, 26.5%). What calls for special attention is that the percentage of death rate for sunitinib was highest (24/54, 44.4%) in sunitinib-related psychiatric ADRs ICSRs, (excluding missing data, n = 44), followed by lenvatinib (4/14, 28.6%). Based on ROR, PRR, BCPNN, and MGPS methods, sorafenib, sunitinib, cabozantinib, and lenvatinib are significantly associated with all ADRs, the strongest association was the association between cabozantinib and feeding disorder. Conclusion: Despite the limitations, our study found that, except for vandetanib, other four drugs have been reported to have significant psychiatric side effects. Clinicians need to recognize and monitor these potentially fatal adverse events. If it is suitable for treatment with vandetanib, doctors should choose vandetanib for treatment.

Hydrogel-Encapsulated Engineered Microbial Consortium as a Photoautotrophic "Living Material" for Promoting Skin Wound Healing.

Genetically modified engineered microorganisms have been encapsulated in hydrogels and used as "living materials" for the treatment of skin diseases. However, their applications are often limited by the epidermal dry, nutrient-poor environment and cannot maintain functions stably for an expected sufficient time. To solve this problem, a photoautotrophic "living material" containing an engineered microbial consortium was designed and fabricated. The engineered microbial consortium comprised Synechococcus elongatus PCC7942 for producing sucrose by photosynthesis and another heterotrophic engineered bacterium (Escherichia coli or Lactococcus lactis) that can utilize sucrose for the growth and secretion of functional biomolecules. These engineered microorganisms in the "living material" were proved to function stably for a longer time than only individual microbes. Subsequently, CXCL12-secreting engineered L. lactis was used to construct the "living material", and its effect on promoting wound healing was verified in a full-thickness rat-skin defect model. The wounds treated by our hydrogel-encapsulated engineered microbial consortium (HeEMC) healed faster, with a wound area ratio of only 13.2% at day 14, compared to the remaining 62.6, 51.4, and 40.8% of the control, PEGDA, and PEGDA/CS groups, respectively. In conclusion, we established an efficient living material HeEMC to offer promising applications in the treatment of skin diseases.
