In hematological malignancies, particularly myelodysplastic syndromes (MDS), acute myeloid leukemia (AML), and chronic myeloid leukemia (CML), TLRs influence inflammation, disease progression, and therapeutic response. This review highlights the prognostic relevance of TLR expression, the role of the MyD88 signaling pathway in clonal evolution, and the dual nature of TLR-mediated immune responses, either promoting antitumor activity or contributing to leukemogenesis. Notably, TLR dysregulation in MDS and AML is associated with poor prognosis and genomic instability, whereas in CML, TLRs contribute to a protective microenvironment via NOD-like and TNF-α pathways. Therapeutic strategies targeting TLRs, including agonists and antagonists, show promise in enhancing antitumor responses, especially when combined with agents like purine nucleoside phosphorylase inhibitors. Furthermore, genetic variations in TLR pathways may influence individual susceptibility to infection and cancer progression, reinforcing the relevance of personalized medicine.

Secreted frizzled-related protein 5 (SFRP5), a Wnt/β-catenin signaling antagonist, has been implicated in various cancers, but its role in HCC remains unclear. This study explores the regulatory interactions between SFRP5, EMT, and Wnt/β-catenin signaling in HCC. Bioinformatics analysis, patient-derived tissue samples, and in vitro experiments revealed significant downregulation of SFRP5 due to promoter hypermethylation. Methylation-specific PCR confirmed extensive SFRP5 methylation, while treatment with 5-Aza-2′-deoxycytidinerestored SFRP5 expression, suppressing Wnt/β-catenin signaling and EMT. Functional assays demonstrated that SFRP5 overexpression inhibited HCC cell proliferation, migration, and colony formation while promoting apoptosis. Western blot and immunofluorescence confirmed that SFRP5 restoration suppressed β-catenin and its targets (MYC, Cyclin D1, Survivin), increased E-cadherin, and decreased mesenchymal markers (Vimentin, Fibronectin, Twist). In vivo xenograft models showed that SFRP5 overexpression reduced tumor growth and EMT marker expression.
