Abstract
Colorectal cancer (CRC) is a major global health concern, and the development of effective treatment strategies is crucial. Enzyme prodrug therapy (EPT) shows promise in combating tumors but faces challenges in achieving sustained expression of therapeutic enzymes and optimal biological distribution. To address these issues, a fungi-triggered in situ chemotherapeutics generator (named as SC@CS@5-FC) was constructed via oral delivery of a prodrug (5-fluorocytosine, 5-FC) for the treatment of orthotopic colorectal tumor. When SC@CS@5-FC targets the tumor through tropism by Saccharomyces cerevisiae (SC), the chemotherapeutic generator could be degraded under abundant hyaluronidase (HAase) in the tumor microenvironment by an enzyme-responsive gate to release prodrug (5-FC). And nontoxic 5-FC was catalyzed to toxic chemotherapy drug 5-fluorouracil (5-FU) by cytosine deaminase (CD) of SC. Meanwhile, SC and zinc-coordinated chitosan nanoparticles could be used as immune adjuvants to activate antigen-presenting cells and further enhance the therapeutic effect. Our results demonstrated that SC@CS@5-FC could effectively inhibit tumor growth and prolong mouse survival in an orthotopic colorectal cancer model. This work utilizes living SC as a dynamotor and positioning system for the chemotherapeutic generator SC@CS@5-FC, providing a strategy for oral enzyme prodrug therapy for the treatment of orthotopic colorectal.

Abstract
As natural living substances, microorganisms have emerged as useful resources in medicine for creating microbe-material hybrids ranging from nano to macro dimensions. The engineering of microbe-involved nanomedicine capitalizes on the distinctive physiological attributes of microbes, particularly their intrinsic "living" properties such as hypoxia tendency and oxygen production capabilities. Exploiting these remarkable characteristics in combination with other functional materials or molecules enables synergistic enhancements that hold tremendous promise for improved drug delivery, site-specific therapy, and enhanced monitoring of treatment outcomes, presenting substantial opportunities for amplifying the efficacy of disease treatments. This comprehensive review outlines the microorganisms and microbial derivatives used in biomedicine and their specific advantages for therapeutic application. In addition, we delineate the fundamental strategies and mechanisms employed for constructing microbe-material hybrids. The diverse biomedical applications of the constructed microbe-material hybrids, encompassing bioimaging, anti-tumor, anti-bacteria, anti-inflammation and other diseases therapy are exhaustively illustrated. We also discuss the current challenges and prospects associated with the clinical translation of microbe-material hybrid platforms. Therefore, the unique versatility and potential exhibited by microbe-material hybrids position them as promising candidates for the development of next-generation nanomedicine and biomaterials with unique theranostic properties and functionalities.

Abstract
Bacteria-based cancer therapy (BCT) has been extensively investigated because of the tumor targeting and antitumor immunity activating abilities of bacteria over traditional nanodrugs, but their potential systemic toxicity poses a challenge. Therefore, it is important to visualize the precise localization and real-time distribution of bacteria in vivo to guide the treatment. Herein, biogenetically engineered Escherichia coli Nissle 1917 (EcN) were constructed to highly express tyrosinase to intracellularly generate cyanine 5-labeled melanin-like polymers (Cy5-Mel), thus endowing them with a bright fluorescence and an excellent photothermal performance upon NIR laser irradiation, thereby inducing the intense immunogenic death of tumor cells and release of tumor-associated antigens. Acting as adjuvants, bacteria can greatly stimulate the maturation of dendritic (DC) cells. The in vivo behaviors of these bacteria was monitored via noninvasive optical imaging when they were intravenously administrated to tumor-bearing mice. From this, NIR exposure on tumor sites was carried out at an appropriate time point to induce the damage to tumor cells and for the modulation of tumor immune microenvironments. Thus, via a simple bioengineering strategy, a promising bacteria-based theranostic platform was constructed for tumor treatment.

Abstract
The impact of the gut microbiome on host health is becoming increasingly recognized. To date, there is growing evidence that the complex characteristics of the microbial community play key roles as potential biomarkers and predictors of responses in cancer therapy. Many studies have shown that altered commensal bacteria lead to cancer susceptibility and progression in diverse pathways. In this review, we critically assess the data for gut microbiota related to gastrointestinal cancer, including esophageal, gastric, pancreatic, colorectal cancer, hepatocellular carcinoma and cholangiocarcinoma. Importantly, the underlying mechanisms of gut microbiota involved in cancer occurrence, prevention and treatment are elucidated. The purpose of this review is to provide novel insights for applying this understanding to the development of new therapeutic strategies in gastrointestinal cancer by targeting the microbial community.
