Article Abstract

(Berk.) is a complex is formed by larvae and . Infestation by , interaction with host larvae, and fruiting body development are three crucial processes affecting the formation of . However, research on the molecular mechanism of formation has been hindered by the lack of effective genetic transformation protocols. Therefore, -mediated transformation (ATMT) was adopted to genetically transform two strains and optimize the transformation conditions. The results revealed that the most suitable strain for transformation was AGL1, and that the surfactant Triton X-100 could also induce ATMT, although less effectively than acetosyringone (AS). In addition, the endogenous promoters of genes had a stronger ability to drive the expression of the target gene than did the exogenous promoter. The optimal transformation conditions were as follows: AS and hygromycin B concentrations of 100 μM and 50 μg/mL, respectively; OD of 0.4; cocultivation at 18 °C for 24 h; and used within three passages. The results lay a foundation for the functional study of key regulatory genes involved in the formation of .

ConspectusMolecular photochemistry, by harnessing the excited states of organic molecules, provides a platform fundamentally distinct from thermochemistry for generating reactive open-shell or spin-active species under mild conditions. Among its diverse applications, the resurgence of the Minisci-type reaction, a transformation historically reliant on thermally initiated radical conditions, has been fueled by modern photochemical strategies with improved efficiency and selectivity. Consequently, the photochemical Minisci-type reaction ranks among the most enabling methods for C()-H functionalizations of heteroarenes, which are of particular significance in medicinal chemistry for the rapid diversification of bioactive scaffolds.

Exosomes derived from various cells have been demonstrated to contribute to cardiac repair by regulating macrophage polarization in myocardial infarction. However, how exosomes secreted from cardiomyocytes under hypoxia-ischemia (Hypo-Exo) regulate macrophage polarization in the local tissues is elusive. This study aimed to determine the underlying mechanisms by which Hypo-Exo polarized M2 macrophages.

Radiation therapy (RT) plays important roles in cancer treatment, and the efficacy of RT depends on the abscopal effect, which results in the regression of distant and untreated tumors through localized irradiation of a single tumor lesion. This effect is mediated by effector tumor antigen-specific T cells (ETASTs) activated by RT. Monitoring the radiation-induced changes in ETASTs can be used to predict the abscopal effect.

Xenogeneic cell transplantation often faces significant immune rejection, even in immunodeficient animal models. Among residual immune components, macrophages can actively phagocytose transplanted human cells, posing a challenge to long-term engraftment. To address this, we developed a standardized in vitro assay to quantify macrophage-mediated phagocytosis of human versus rat red blood cells (RBCs).

There is growing interest in understanding the mechanisms underlying differences in cancer incidence among species (comparative oncology). The naked mole-rat (NMR) is often referenced as "cancer-resistant" and prior studies focused on identifying mechanisms explaining this. However, efforts to assess this in vivo have been limited.
