Exhausted CD8+ T cells overexpress CCL5 during combination therapy to mediate resistance of hepatoma cells to lenvatinib: one situation may contribute to the survival of residual tumor cells

ABSTRACT: In conclusion, we discovered that during combination therapy, tumor tissue demonstrated a more active metabolic reprogramming than normal liver tissue, as indicated by a significant upregulation of CYP1A1 expression. In addition, we validated that CD8T cells secreted more CCL5 after treatment, which upregulated CYP1A1 expression by binding to CCR5, leading to resistance of hepatoma cells to lenvatinib. Finally, we demonstrated that interference with the CCL5/CCR5/CYP1A1 pathway can enhance the efficacy of lenvatinib and combination therapy.

Project description:Senescent foamy macrophages are the key pathogenic drivers of atherosclerosis (AS) progression and plaque stability. The RNA N6-methyladenosine (m6A) modification plays an important role in the development of various diseases. However, its role in foamy macrophage aging during AS is still not clarified. To assess m6A methylation levels and m6A modifying enzyme profiles, the infiltrated macrophages were sorted using CD68+ magnetic beads from plaque tissues of patients with AS and high-fat diet feeding Apoe-/- mice. The ALKBH5f/f, Lyz2Cre, Apoe-/- mice were constructed to observe senescent macrophage infiltrated in plaques and AS progression. The RNA-seq, MeRIP, RIP and dual luciferase assays were performed to explore the mechanisms of ALKBH5-mediated formation of senescent macrophage. Downregulated m6A methylation levels and upregulated ALKBH5 expression were observed in aortic plaques and infiltrated macrophages from AS patients and mice. Compared with control mice, ALKBH5f/f, Lyz2Cre, Apoe-/- mice decreased AS plaques and enhanced plaque stability by suppressing senescence of foamy macrophages and senescence-associated secretory phenotypes. In addition, the data of the RNA-seq, MeRIP, RIP and dual luciferase assays showed that ALKBH5 deletion reduced the mRNA level of CC chemokine ligand 5 (CCL5) by increased m6A methylation in macrophages. Actinomycin D assay indicated ALBH5 knockout destroyed stability of Ccl5 mRNA. Mechanismly, ALKBH5 promotes senescent macrophage formation by CCL5/CC chemokine receptor 5 (CCR5)/mTORC1/autophagy signaling. And ALKBH5 induced macrophage derived CCL5 recruits increasingly CD8+IFNγ+ T cells by CCL5-CCR5 axis. Furthermore, the application of ALKBH5 inhibitor IOX-1 and CCR5 monoclonal antibody Adaptavir are potential clinical interventions for the inhibition of senescent macrophage formation and AS progress. Myeloid ALKBH5 deletion mitigates AS progression by suppressing the formation of senescent macrophages and the recruitment of CD8+IFNγ+ T cells. These findings favour the ALKBH5/CCL5/CCR5 signaling as novel targets for atherosclerosis therapy.

Project description:Rates of hepatocellular carcinoma (HCC) are increasing rapidly due to the epidemic of metabolic dysfunction-associated steatohepatitis (MASH). In addition to increased incidence, emerging evidence suggests that MASH driven HCC is associated with poor survival outcomes potentially due to the complex liver microenvironment which is characterized by hypoxia, steatosis, and fibrosis. Lenvatinib, is a multi-tyrosine kinase inhibitor, that is a standard of care therapy for unresected HCC, but 5-year survival rates are less than 20%. Therefore, developing treatments that inhibit cancer growth kinetics and target the tumor microenvironment to improve the therapeutic response in MASH-HCC are needed. Salsalate is a rheumatoid arthritis therapy that stimulates the AMP-activated protein kinase (AMPK) increasing fatty acid oxidation while reducing de-novo lipogenesis, fibrosis and cell proliferation pathways. Thus, we hypothesized that Salsalate could improve the therapeutic efficacy of Lenvatinib in MASH-HCC. In the current study, we show that treatment of human HCC cells with clinically relevant concentrations of Lenvatinib and Salsalate synergistically suppress proliferation and clonogenic survival, activate AMPK and inhibit the mTOR-HIF1a and Erk1/2 signaling pathways. In orthotopic xenograft and MASH-HCC mouse models Lenvatinib and Salsalate combination therapy suppressed angiogenesis and steatosis and fibrosis. RNA-sequencing revealed combination therapy enhanced mitochondria fatty acid oxidation and suppressed glycolysis, angiogenesis, fibrosis and cell cycle progression with regulatory network analysis suggesting a potential role for Activating transcription factor 3 (ATF3) and ETS-proto-oncogene-1 (ETS1). These data suggest that Lenvatinib and Salsalate combination therapy may have therapeutic potential for MASH-HCC due to effective metabolic rewiring and growth inhibition, leading to improvements in the liver microenvironment and inhibition of HCC proliferation.
