Abstract Background The complexity of biological systems has increasingly been unraveled through computational methods, with network analysis now focusing on the construction and exploration well-defined interaction networks. Traditional graph-theoretical approaches have instrumental in mapping key processes using high-confidence data. However, these methods often struggle incomplete or/and heterogeneous datasets. In this study, we extend beyond conventional bipartite models by integrating attribute-driven knowledge from Molecular Signatures Database (MSigDB) node2vec algorithm. Results Our approach explores unsupervised relationships uncovers potential associations between genes terms connectivity analysis. By embedding both human mouse data into a shared vector space, validate our findings cross-species, further strengthening robustness method. Conclusions This integrative framework reveals expected novel insights, offering comprehensive perspective that complements traditional paves way for deeper understanding complex diseases.

Abstract The chaperonin containing TCP1 subunit 5 (CCT5) is believed to function as a tumor driver. However, systematic pan-cancer analysis of CCT5 still lacking. Therefore, this study aimed identify the potential role in different types tumors. This comprehensively investigated gene expression, proteomic immune infiltration, DNA methylation, genetic alterations, correlation with TMB and MSI, drug sensitivity, enrichment analysis, prognostic significance 33 tumors based on TIMER2.0, GEPIA2, UALCAN, SMART, cBioPortal, GSCA databases, TCGAplot R package. results revealed significant overexpression most was significantly associated poor OS DFS types. Reduced promoter N-shore methylation CCT5, indicating its oncogenic epigenetic roles. Amplification common type alterations. Immune infiltration strong between cells. exhibited MSI KIRC STAD. Furthermore, associations cell cycle pathway various cellular functions. These findings suggested that might serve biomarker target for immunotherapy cancers.

Abstract CCT5, a molecular chaperone protein, was analyzed in 33 different tumor types by pan-cancer analysis. This study investigated various aspects such as gene expression, proteomic immune infiltration, DNA methylation, genetic alterations, survival, enrichment analysis, and prognostic significance. The results showed that CCT5 is highly expressed most tumors, its overexpression associated with poor overall disease-free well prognosis types. Immune infiltration analysis revealed correlation between cancer-associated fibroblasts (CAFs), CD8 + T cells, NK the of patients significantly correlated expression these three tumor-infiltrating cells. suggested regulates number thereby affecting tumors. Enrichment association cell cycle RNA-binding pathways. reduced promoter N-shore indicating potential oncogenic epigenetic roles. These findings suggest may serve biomarker target for immunotherapy cancer proliferation development.

Hemoglobin H/Constant Spring (Hb H/CS) disease represents a form of non-deletional Hb H characterized by chronic hemolytic anemia that ranges from moderate to severe and may lead transfusion-dependent thalassemia. To study the underlying mechanisms this disease, we conducted an analysis erythropoiesis gene expression in erythroid progenitor cells derived CD34+ hematopoietic stem/progenitor patients with H/CS normal controls. Twelve five controls were enrolled. Peripheral blood samples collected isolate for cell proliferation differentiation. Six three subsequently studied next generation sequencing analysis. Erythroid exhibited trend towards increased rates decreased viability compared those Moreover, demonstrated delayed terminal Gene profiling revealed elevated levels genes encoding molecular chaperones, including heat shock protein (HSPs) chaperonin containing TCP-1 subunit (CCTs) group. In summary, exhibit heightened proliferation, diminished viability, Additionally, chaperones was observed, providing information on potential pathophysiological mechanisms.
