TYROBP (Transmembrane Immune Signaling Adaptor TYROBP)

Cell-cell interaction analysis showed that the increased CD44-TYROBP-mediated and decreased PPIA-BSG and APP-SORL1-mediated cell communication between tumor cells and other cells.Specifically, CD8+ resident memory T cells emerged as pivotal regulators in LM of PTC, primarily through the expression of MHC-I, CD99 and LCK. This study provides new insights into the heterogeneity of PTC and the basis for LM in PTC, which might provide potential therapeutic targets in future treatment.

TYROBP knock-down blunts dissemination, whereas enforced TYROBP expression exacerbates metastasis-effects reversed by baicalein. Thus, the SP1-TYROBP-CTSZ axis licenses PDAC metastasis, and baicalein-mediated TYROBP inhibition offers a tractable therapeutic strategy.

CM was divided into two subtypes based on immune gene expression, with the C1 subtype associated with poor prognosis. A prognostic risk model was developed using these classifications to predict patient outcomes.

This study provides a comprehensive view of the heterogeneity of the liver cancer TME and reveals the potential roles of key genes and cell types in the development of liver cancer. These findings offer new insights into the molecular mechanisms of liver cancer and may aid in the identification of new therapeutic targets and biomarkers.

Our study reveals that high TYROBP expression is associated with increased M2 macrophage infiltration in PDAC, promoting a pro-tumorigenic TME. TYROBP overexpression drives macrophage polarization towards the M2 phenotype, enhances glycolytic activity, and modulates key signaling pathways. Baicalein, targeting STAT3, shows potential as a therapeutic agent for PDAC by inhibiting cell proliferation and modulating the TME. These findings highlight TYROBP as a key regulator in PDAC progression and suggest potential therapeutic strategies targeting TYROBP and its associated pathways.

Drug sensitivity analysis associated MASP1 with enhanced response to doxorubicin, vinblastine, gemcitabine, and sorafenib. These findings could help to improve patient prognosis and the treatment response. Further studies should be conducted explore MASP1 clinical applications.

For metastatic cases: inflammatory response(logp-value=-9.2:ADGRE5/2,CYBA,GRN,HMOX1,IRF5,ITGAM), adaptive immunity(logp-value=-7.7:CD1C,CD74,CYBB,NCF2,CTSA,S100A8/9,BCL3,FCER1G), T-cell activation(logp-value=-6.3:BCL3,CD1C,CD74,FCER1G,FGL2)and lipid metabolism/catabolism(logp-value=-2.5/-2.6:ARF3,GPX1,MVD,OCRL,PCCB,CTSA,PNPLA2,NAGLU,GBA2,ABHD4); while in early-progressors to ICIs: immune effector processing(logp-value=-13.7:BCL6,FGR,HLA-DQA1/DQB1,HLA-DRA,HLA-DRB1/DRB5,NKG7,SLC11A1,TYROBP,SPON2,HAVCR2),PD-1(logp-value=-10.2:HLA-DQA1/DQB1,HLA-DRA,HLA-DRB1/DRB5)and IFN signaling(logp-value=-8.5: HLA-DQA1/DQB1,HLA-DRA,HLA-DRB1/DRB5,NCAM1,IFITM3),positive regulation of T-cell activation(logp-value=-7.7:BCL6,HLA-DQA1/DQB1,HLA-DRA,HLA-DRB1/DRB5,SASH3,HAVCR2)and CD28 co-stimulation(logp-value=-10.3:HLA-DQA1/DQB1,HLA-DRA,HLA-DRB1/DRB5), supporting an immune-mediated behavior. Specific pathways and marker genes in the peripheral CD4+T-cells may predetermine melanoma staging and immunotherapy resistance.

In conclusion, SCLC patients with low ITGB2 expression exhibited worse prognosis. ITGB2 might be correlated with immunotherapy response of SCLC patients.

This study identified two hub genes, MET and FAM20A, with potential diagnostic value in HT and PTC.

This study elucidates that TYROBP plays a direct role in promoting PC metastasis through its association with M2 TAMs polarization. Therefore, TYROBP represents a potential novel therapeutic target for interventions aimed at combatting PC progression.

We identified immune cells that may play a role in the progression from DCIS to IDC and uncovered five key genes that can serve as prognostic markers for breast cancer. These findings provide insights into the mechanisms underlying the transition from DCIS to IDC, offering valuable perspectives for future research. Additionally, our results contribute to a better understanding of the biological processes involved in breast cancer progression.

This study indicates that CD53, FCER1G, and TYROBP play a role in the development of HT and PTC, and may contribute to the progression of HT to PTC. These hub genes could potentially serve as diagnostic markers and therapeutic targets for PTC and HT.
