Role of Fungi in Tumorigenesis: Promises and Challenges.

The mycobiome plays a key role in the host immune responses in homeostasis and inflammation. Recent studies suggest that an imbalance in the gut's fungi contributes to chronic, noninfectious diseases such as obesity, metabolic disorders, and cancers. Pathogenic fungi can colonize specific organs, and the gut mycobiome has been linked to the development and progression of various cancers, including colorectal, breast, head and neck, and pancreatic cancers.

The high morbidity and mortality of colorectal cancer (CRC) is a major challenge in clinical practice. Although a series of alternative research models of CRC have been developed, appropriate orthotopic animal models that reproduce the specific clinical response as well as pathophysiological immune features of CRC are still lacking. In the current study, we constructed a CRC orthotopic xenograft model by implanting the tumor tubes at the colorectum of mice and monitored the model development using bioluminescence imaging.

Tumor-associated macrophages (TAMs) are commonly considered accomplices in tumorigenesis and tumor development. However, the precise mechanism by which tumor cells prompt TAMs to aid in evading immune surveillance remains to be further investigated. Here, it is elucidated that tumor-secreted galectin-1 (Gal1) conferred immunosuppressive properties to TAMs.

The development of mesothelin (MSLN) epitope reactive T cells is observed in mice that are immunized with the MSLN vaccine. Engineered T cells expressing MSLN-reactive high-affinity TCR exhibit extraordinary therapeutic effects for invasive pancreatic ductal adenocarcinoma in a mouse model. However, the generation of MSLN-reactive T cells through the introduction of MSLN-deficient thymus and the transplantation of the latter as a cure for cancer treatment have not been tested to date.

Sterol composition plays a crucial role in determining the ability of yeast cells to withstand high temperatures, an essential trait in biotechnology. Using a targeted evolution strategy involving fluconazole (FCNZ), an inhibitor of the sterol biosynthesis pathway, and the immunosuppressant FK506, we aimed to enhance thermotolerance in an industrial baker's yeast population by modifying their sterol composition. This approach yielded six isolates capable of proliferating in liquid YPD with μ values ranging from 0.
