IFIT1 (Interferon Induced Protein With Tetratricopeptide Repeats 1)

Functional validation demonstrated GRN's critical role in driving epithelial-mesenchymal transition in vitro and conferring resistance to enzalutamide (ENZ) in patient-derived organoids...Furthermore, we identified three novel stromal populations [decorin (DCN)+ endothelial cells, C-C motif chemokine ligand 7 (CCL7)+ fibroblasts, and interferon-induced protein with tetratricopeptide repeats 1 (IFIT1)+ neutrophils associated with disease relapse. These findings illuminate the tumor-immune crosstalk underlying treatment resistance and unveil promising therapeutic targets for overcoming lineage plasticity-driven resistance in advanced prostate cancer.

SYNOPSIS: Clostridium sporogenes alleviates acute and chronic liver injury and inflammation through its metabolite 5-aminovaleric acid (5-AVA). 5-AVA suppresses M1 macrophage activation by upregulating IFIT1, inhibiting the NF-κB pathway, and exerting hepatoprotective effects.

In vivo experiments using an orthotopic xenograft tumor model in mice further confirmed that the SNRPF/TMED2/cGAS-STING axis significantly promotes the growth and progression of HCC tumors. In conclusion, this study elucidates the pivotal oncogenic function of the SNRPF/TMED2/cGAS-STING signaling axis in HCC, providing novel strategies for prognosis prediction and targeted therapy.

Inactivation of PTEN inhibited interferon regulatory factor 3 (IRF3) nuclear translocation, leading to reduced IFN-β expression. Thus, our findings uncover a previously uncharacterized SOX3-AKT1-PTEN signaling axis in the regulation of antiviral innate immunity, providing new insights into immune evasion strategies and highlighting potential therapeutic targets to enhance antiviral responses.

This investigation elucidates the potential role of immune dysregulation underlying GWI, emphasising the importance of immune exhaustion pathways in disease progression. Further investigations in a larger cohort may further elucidate or confirm these identified markers for potential screening or therapeutic applications in GWI.

Stimulation of the OS TME can change the gene expression of macrophages. Our findings offer a cellular and molecular reference for future investigations of therapeutic targets of OS.

Despite limited sample size, the combination of single-cell transcriptomics, clinical survival data, and protein-level validation provides robust evidence of age-specific TME remodeling. These findings support the development of age-tailored immunotherapy strategies targeting interferon signaling in young patients and immune checkpoint pathways (e.g., LAG3, CTLA4) in elderly individuals.

Mechanistically, NK cell-mediated innate allorecognition drives this early intra-allograft specific neutrophil phenotypic programing. These findings provide novel insights into the innate immune allorecognition-mediated regulation of the plasticity of recently described key neutrophil subsets and will enable specific targeting to neutralize detrimental neutrophil subsets and enhance solid organ transplant outcomes.

Additionally, it uncovered promising drug candidates-etoposide, mevastatin, oxfendazole, HDAC inhibitors, and TIGIT blockade-as well as immunotherapies like PD-1 inhibition and adoptive CD8+ T cell therapy...While technical challenges remain, it paves the way for more personalized and effective treatment strategies. However, the current findings are subject to limitations, including technical biases in single-cell protocols and the exclusion of non-English literature, which may affect generalizability.

The impact of glycolytic inhibition by 2-Deoxy-D-glucose (2-DG) on CAR-NK92 antitumor capacity was examined...Conclusion ATPIF1 regulates the antitumor activity of CAR-NK92 cells through modulating glycolytic metabolism. Overexpression of ATPIF1 can enhance the antitumor efficacy of CAR-NK92 cells.

We found highly analogous insertions, deletions, and functional annotations of the detected single nucleotide polymorphisms and indel mutations in PWH and patients with HIV-negative CRC. This study provides new insights into crucial ISGs, immune infiltration, immune variants, and pathways involved in CRC with HIV infection.

Additionally, they have also been reported to be a part of various clinical predictive models in cancers. This review provides an overview of the current understanding of IFIT proteins' involvement in cancers, with an emphasis on their emerging roles as clinically relevant biomarkers.
