EPSTI1 (Epithelial Stromal Interaction 1)

This study sheds light on the molecular mechanisms of KRAS-mutated CRC, emphasizing IL1B as a prognostic marker. Among the identified therapeutic agents, Omeprazole demonstrated the strongest interaction with AHR, suggesting a potential for repurposing in CRC treatment, while IL1B-targeting inhibitors such as Canakinumab emerged as selective candidates for modulating tumor-promoting inflammation. Novel genes such as EPSTI1, COL20A1, CDH1, and SOX9 warrant further investigation.

The TME-specific gene-based prognostic model effectively predicts survival outcomes in pediatric brain tumors, offering promising biomarkers for personalized medicine and potential therapeutic targets. However, further research is required to validate these findings across different tumor subtypes and to explore their clinical applications.

Our results reveal the molecular mechanism by which hsa_circ_0000479 promotes GC progression through BTRC-mediated competitive binding to G3BP1 to inhibit its ubiquitination-mediated degradation, which provides a new theoretical basis for the targeted treatment of GC and elucidates the potential of hsa_circ_0000479-G3BP1-BTRC as a therapeutic target in GC. These findings provide a new direction for the treatment of patients with GC.

Subsequently, we conducted drug sensitivity analysis and immune checkpoint analysis, revealing that the majority of drugs are more sensitive to low-risk patients, while ABT-888, AS601245, and CCT007093 may have greater potential clinical benefits for high-risk patients. Immune checkpoint analysis showed significant differences in the expression of ADORA2A, BTLA, CD276, CD27, CD28, CD40LG, CD48, and TNFRSF14 between high-risk and low-risk patient groups, suggesting their potential as therapeutic targets for LUAD..

In line with the notion, mice lacking Epsti1 exhibit exacerbated muscle atrophy accompanied by increased inflammatory response in cancer cachexia model. Our study suggests a crucial function of Epsti1 in the resolution of IFN-γ-JAK-STAT1 signaling through interaction with VCP which provides insights into the unexplored mechanism of crosstalk between inflammatory response and muscle regeneration.

After exposure to pDNA-melittin, there was no significant increase in transcription levels of caspase-3, caspase-8, BCRA1, BAX, Drp1, AKT1, and EPSTI1 genes in the normal non-cancerous groups. The findings provide novel opportunities for the therapeutic targeting of malignancies via melittin and the stimulation of the EPSTI1/Drp1/AKT1 signaling cascades.

Additionally, five crucial miRNAs (hsa-miR-8060, hsa-miR-6890-5p, hsa-miR-5003-3p, hsa-miR-6893-3p, and hsa-miR-6069), five essential transcription factors (CREB1, CEBPB, EGR1, EP300, and IRF1), and the top ten significant drug chemicals (estradiol, progesterone, tretinoin, calcitriol, fluorouracil, methotrexate, lipopolysaccharide, valproic acid, silicon dioxide, cyclosporine) were identified. This research provides valuable insights into shared molecular targets, signaling pathways, drug chemicals, and potential biomarkers for individuals facing the complex intersection of COVID-19, influenza, and HIV. These findings hold promise for enhancing the precision of diagnosis and treatment for individuals with HIV co-infected with COVID-19 and influenza.

When instead diagnosing patients based on the combination of MIF and circEPSTI1, the Area further rose to 0.8604. Assessing the combination of circEPSTI1 and MIF may be a viable approach to reliably diagnosing EC.

Finally, the subpopulation-enriched targets and drugs were confirmed through ConnectivityMap (CMAP) analysis and multi-omics, respectively. In this study, positive samples for CXCL13, EPSTI1, and CDK1 exhibited poor prognostic significance in treatment-naïve LUAD cases but demonstrated benefits from PD-L1 blockade and dasatinib therapies.

Circ_0000129 relieved Sev-triggered suppression impacts on breast cancer development partly via the miR-578/EPSTI1 axis, which provides a new mechanism for studying mediated therapy of breast cancer treatment.

Tumor-derived PCSK9 plays a critical role in melanoma pathogenesis. PCSK9's oncogenic actions are associated with intratumoral cholesterol accumulation. PCSK9 systemically affects the immune system, contributing to melanoma immune evasion. Novel biomarkers derived from the PCSK9-network effectively predicted ICB therapy responses.

The TME immune score is positively associated with better survival outcomes. EPSTI1 could serve as a novel immune prognostic biomarker for stage III CC.
