Tumor recurrence after radiofrequency ablation (RFA) affects the survival rate of patients and limits its clinical application. around area may be related to thermal injury hepatocytes (HCs) tumor, but specific mechanism is still unclear. A liver cancer mouse model was established via RFA in C57BL/6 mice. Primary HCs Kupffer cells (KCs) were isolated cultured assess their sensitivity MTT assay. Flow cytometry used macrophage polarization. Furthermore, Western blotting co-immunoprecipitation (co-IP) utilized evaluate protein expression intracellular signaling pathway. Finally, Transwell wound healing assays conducted invasion potential cells. Our findings revealed that RFA-induced promoted upregulation secretion HMGB1 HCs. had a protective effect on injury, potentially mediated through autophagy regulation. Heat-injured release HMGB1, which activates TREM1/JAK2/STAT3 pathway KCs, thus fostering an immunosuppressive tumor microenvironment (TME). Moreover, by heat-injured exacerbates migration HCC influencing triggers from HCs, driving M2 polarization increasing ability These reveal therapeutic target for combating following ablation.

Macrophages are crucial immune cells within the tumor microenvironment (TME), involved in regulating proliferation, invasion, metastasis, ECM remodeling, angiogenesis, and immunosuppression. Although more experimental evidence clinical data indicate that macrophages onset progression of oral squamous cell carcinoma (OSCC), exact pathogenesis OSCC associated with has not been fully elucidated. Enhanced knowledge molecular mechanisms involving will aid creation treatments targeted specifically at macrophages. This review outlines pro-tumoral anti-tumoral effects OSCC, emphasizing interaction between It can provide theoretical basis for establishment complex regulatory network centered on explore novel therapeutic strategies OSCC.

N6-methylation is a modification in which methyl group added to the adenine base of nucleotide. This crucial for controlling important functions that are vital gene expression, including mRNA splicing, stability, and translation. Due its intricate participation both normal cellular processes course disease, as well critical role determining cell fate, N6-methyladenosine (m 6 A) alteration has recently attracted lot interest. The formation progression many diseases, especially cancer, can be attributed dysregulated m A alteration, cause disturbances variety functions, such immunological responses, proliferation, differentiation. In this study, we examine how dysregulation affects hepatocellular carcinoma (HCC), with particular emphasis on it contributes evasion carcinogenesis. We also investigate potential novel therapeutic target, providing new perspectives approaches meant enhance clinical results patients HCC.

Hepatocellular carcinoma (HCC) is the most prevalent primary liver malignancy and a leading cause of cancer-related deaths globally. The asymptomatic progression early-stage HCC often results in diagnosis at advanced stages, significantly limiting therapeutic options worsening prognosis. Immunotherapy, with immune checkpoint inhibitors (ICIs) forefront, has revolutionized treatment. Nevertheless, tumor heterogeneity, evasion, presence immunosuppressive components within microenvironment (TIME) continue to compromise its efficacy. Furthermore, resistance or non-responsiveness ICIs some patients underscores urgent need unravel complexities TIME design innovative strategies that enhance immunotherapeutic outcomes. Emerging evidence revealed pivotal role N6-methyladenosine (m6A), prominent RNA methylation modification, shaping HCC. By regulating stability translation, m6A influences immune-related factors, including cytokines molecules. This modification governs PD-L1 expression, facilitating escape contributing against ICIs. Advances this field have also identified m6A-related regulators as promising biomarkers for predicting immunotherapy response potential targets optimizing treatment review examines regulatory mechanisms HCC, focus on impact cells cytokine dynamics. It explores targeting pathways improve efficacy outlines emerging directions future research. These insights aim provide foundation developing novel overcome advance

RNA modifications are epigenetic changes that alter the structure and function of molecules, playing a crucial role in onset, progression, treatment cancer. Immune checkpoint inhibitor (ICI) therapies, particularly PD-1 blockade anti-CTLA-4 treatments, have changed landscape virous cancers, showing great potential different cancer patients, but sensitivity to these therapies is limited certain individuals. This review offers comprehensive survey functions therapeutic implications four principal modifications, highlighting significance m6A realms immune cells tumor immunotherapy. starts by providing foundational summary roles assume within cell community, focusing on T cells, NK macrophages, dendritic cells. We then discuss how influence intricate regulatory mechanisms governing expression, modulation ICI efficacy, prediction outcomes, drug targeting genes regulated modifications. Finally, we explore gene editing, vaccines, adoptive offering valuable insights into use

Hepatocellular carcinoma (HCC) tissue is rich in dendritic cells, T B macrophages, natural killer cells and cellular stroma. Together they form the tumor microenvironment (TME), which also numerous cytokines. Tumor‑associated macrophages (TAMs) are involved regulation of development. TAMs HCC receive stimuli different directions, polarize directions release cytokines to regulate development HCC. mostly divided into two cell phenotypes: M1 M2. secrete pro‑inflammatory mediators, M2 a variety anti‑inflammatory pro‑tumorigenic substances. The TAM polarization tumors Both direct indirect methods for discussed. indirectly support by promoting peripheral angiogenesis regulating immune TME.
