Chidamide and Anlotinib Synergistically Inhibit High Grade B-Cell Lymphomas via PI3K/AKT Signaling Pathway

Project description:High-grade B-cell lymphoma with concurrent MYC and BCL2/BCL6 rearrangements (HGBL-DHL) presents a formidable challenge, often refractory and resistant to front-line immunochemotherapies, necessitating urgent exploration of novel therapeutic approaches. Herein, we unveiled a robust synergistic anti-lymphoma efficacy of chidamide and anlotinib against HGBL-DHL. The cooperative effect of cell proliferation inhibition, apoptosis induction, and cell cycle arrest were demonstrated in cell lines through Cell Counting Kit-8, and Annexin V/PI staining, respectively. Moreover, in an HGBL-DHL-xenografted mouse model, the combination therapy markedly reduced tumor burden without inducing fatal toxicity. Mechanistically, chidamide suppressed HDAC3, while anlotinib inhibited VEGFR2, leading to down-regulation of the PI3K/AKT signaling cascade. This dual suppression was by their synergistic effect. Collectively, our preclinical findings underscored the synergistic activity of chidamide and anlotinib combination against HGBL-DHL, warranting further clinical evaluation of this regimen for treating this challenging entity.

Chidamide inhibits double expressor lymphoma through repressing Myc expression and activity

Project description:Double-expressor lymphoma (DEL), defined by MYC and BCL-2 overexpression without corresponding chromosome translocations, is often associated with poor outcomes for standard treatment (R-CHOP). Recently, inhibitors of histone deacetylases have shown great effect in T cell lymphomas. However, its effects on B cell lymphomas are mild. Here, our clinical retrospective analysis showed that HDAC inhibitor chidamide combined with R-CHOP (CR-CHOP) can dramatically increase the complete remission rate of patients with DEL. And the sensitivity of B cell lymphoma cell lines to chidamide is negatively correlated to Myc level. From Western blots and transcriptomics analysis, we found that chidamide treatment could reduce Myc protein level and downregulate the transcription levels of corresponding Myc downstream targets. Thus our results indicate that HDAC inhibitor chidamde holds great potential for treating DEL, which likely functions through inhibiting the Myc pathway.

CREBBP cooperates with cell cycle machinery to attenuate chidamide sensitivity in relapsed/refractory DLBCL

Project description:Frequent inactivating mutations of histone acetyltransferase CREBBP is a characteristic feature of diffuse large B-cell lymphoma (DLBCL), highlighting the attractiveness of targeting the CREBBP deficiency as a therapeutic strategy. In this study, we demonstrate that chidamide, a novel histone deacetylase (HDAC) inhibitor, is effective in treating a subgroup of relapsed/refractory DLBCL patients, achieving an overall response rate (ORR) of 25.0% and a complete response (CR) rate of 15.0%. However, the clinical response to chidamide remains poor as most patients exhibit resistance, hampering the clinical utility of the drug. Functional studies in both in vitro and in vivo models showed that CREBBP loss of function is correlated with chidamide sensitivity, which is associated with modulating cell cycle machinery. A combinatorial drug screening of 130 kinase inhibitors targeting cell cycle regulators identified AURKA inhibitors, which inhibited G2/M transition during cell cycling, as top candidates that synergistically enhanced antitumor effects of chidamide in CREBBP-proficient DLBCL cells. Our study demonstrated that CREBBP inactivation can serve as a potential biomarker to predict chidamide sensitivity, while a combination of AURKA inhibitor and chidamide provides a novel therapeutic strategy for the treatment of relapsed/refractory DLBCL.

Role of Anlotinib-induced CCL2 decrease in anti-angiogensis and response prediction for Non-Small Cell Lung Cancer therapy

Project description:Purpose: Our previous clinical trials have been demonstrated that Anlotinib can inhibit tumor growth upon refractory advanced non-small cell lung cancer (NSCLC) patients with the possibility mechanism of anti-angiogenesis. The present study sought to reveal the underlying molecular mechanism of Anlotinib-induced anti-angiogenesis in advanced NSCLC. Experimental Design: Computed tomography (CT) was used to evaluate the treatment effect of Anlotinib upon refractory advanced NSCLC patients. Transcriptome profiling was performed to identify the key gene expression alteration in NCI-H1975 cells before and after Anlotinib treatment. NCI-H1975 derived xenograft model was applied to investigate treatment effect and verify anti-angiogenesis mechanism of Anlotinib. Results: Anlotinib induces tumor cytotoxicity on refractory advanced NSCLC patients, NCI-H1975 derived xenograft models and lung adenocarcinoma cell lines. Transcriptome profiling revealed CCL2 blockade could be responsible for Anlotinib-induced anti-angiogenesis. NCI-H1975 derived xenograft model demonstrated Anlotinib-induced CCL2 blockade play an important role in anti-angiogenesis. Conclusions: This study not only offered the first evidence that Anlotinib inhibits angiogenesis via blocking CCL2 expression, but also provided a novel theoretical basis for the application of Anlotinib in advanced NSCLC patients.

Chromatin accessibility analysis uncovers TFAP2A as a regulator on pro-angiogenesis of acquired resistance to anlotinib

Project description:Anlotinib, a multitarget agent a multi-target agent that inhibits tumor proliferation and angiogenesis, has been demonstrated to be effective for non-small cell lung cancer (NSCLC) at third-line or over third-line. However, the underlying mechanisms of anlotinib acquired-resistance is still unclear. Here we performed chromatin accessibility profiling on anlotinib-resistant NCI-H1975 and wild-type NCI-H1975. By integrating with transcriptome analysis, we found that anlotinib resistance was due to increased angiogenic capacity, and revealed that TFAP2A was involved in anlotinib resistance. Next, TFAP2A was knock-down in anlotinib-resistant cells and RNAseq was performed to see down-regulated genes with TFAP2A KD.
