The mRNA and protein levels of target genes in TNBC cells and their exosomes were detected by RT-qPCR and western blot. Co-culture models of TNBC cells and THP-1/M0 macrophages was established to detect the impact of co-culture on FOXM1 expression and macrophage polarization direction. The bioinformatics website was used to predict the binding sites between the FOXM1 and IDO1 promoter, which were further validated using dual-luciferase reporter assay and chromatin immunoprecipitation (ChIP) assay. Finally, after erastin-induced ferroptosis, Cell Counting Kit-8 (CCK-8), terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL), and other experiments were conducted to investigate whether the FOXM1/IDO1 axis regulates M2 macrophage polarization through ferroptosis. It was found that FOXM1 was highly expressed in exosomes derived from TNBC cells, and TNBC cells upregulated FOXM1 expression in THP-1 cells through exosomes to promote M2 macrophage polarization. Furthermore, FOXM1 upregulated IDO1 in M2-type TAMs by regulating transcription. Lastly, FOXM1/IDO1 inhibited ferroptosis, promoting M2 macrophage polarization, thereby advancing TNBC progression.

A comprehensive analysis of OsRR family members covered their physicochemical properties, chromosomal distribution, subcellular localization, phylogeny, gene structure, distribution of conserved motifs and domains, and gene duplication events. Gene Ontology analysis indicated that 22 OsRR genes contribute mainly to the cytokinin response and signal transduction. Predicted cis-elements in RR promoter sequences related to phytohormones and abiotic stresses indicated that RRs are involved in hormonal and environmental responses, supporting previous studies.

Two major subspecies, japonica and indica, are observed in Asian cultivated rice (Oryza sativa L.). Previously, we identified (3R)-β-tyrosine, a novel nonproteinogenic β-amino acid in plants, along with the enzyme tyrosine aminomutase (TAM1), which is required for β-tyrosine biosynthesis, in the japonica cultivar Nipponbare. Notably, TAM1 and β-tyrosine were preferentially distributed in japonica cultivars compared with indica cultivars. Considering its phytotoxicity and antimicrobial activity, intraspecific variation in β-tyrosine may contribute to the defensive potential of japonica rice. Investigation of the evolutionary trajectory of TAM1 and β-tyrosine should enhance our understanding of the evolution of rice defense. However, their distribution patterns in O. rufipogon, the direct ancestor of O. sativa, remain unclear. Therefore, in this study, we extensively examined TAM1 presence/absence and β-tyrosine content in 110 genetically and geographically diverse O. rufipogon accessions and revealed that they are characteristically observed in the ancestral subpopulation of japonica rice, while being absent or slightly accumulated in other subpopulations. Thus, we conclude that TAM1 and β-tyrosine in japonica rice are likely derived from its ancestral subpopulation. Furthermore, the high and low TAM1 possession rates and β-tyrosine content in japonica and indica rice, respectively, could be attributed to distribution patterns of TAM1 and β-tyrosine in their ancestral subpopulations.
