Impact of LCL161 on gene expression in human TAC T cells stimulated with antigen-coated microbeads

ABSTRACT: SMAC mimetics such as LCL161 are a novel class of anti-cancer drug that have been shown to induce costimulation in human T cells and augment anti-tumor capabilities. We investigated what impacts LCL161 has on gene expression in engineered anti-BCMA TAC T cells. TAC T cells were stimulated with BCMA-coated microbeads to deliver controlled antigenic signal alone.

Expression data from MDA-MB-231 parental and xenograft tumor cells treated with Smac mimetic SM-164.

Project description:Small-molecule Smac mimetics target inhibitor of apoptosis (IAP) proteins to induce TNFÎ±-dependent apoptosis in cancer cells and several Smac mimetics have been advanced into clinical development as a new class of anticancer drugs. However, preclinical studies have shown that only a small subset of cancer cell lines are sensitive to Smac mimetics used as single agents and these cell lines are at risk of developing drug resistance to Smac mimetics. Thus, it is important to understand the molecular mechanisms underlying intrinsic and acquired resistance of cancer cells to Smac mimetics in order to develop effective therapeutic strategies to overcome or prevent Smac mimetic resistance. We established Smac mimetic resistant sublines derived from MDA-MB-231 breast cancer cells, which exhibit exquisite sensitivity to the Smac mimetic SM-164, and used microarrays to detail the global programme of gene expression underlying SM-164 resistance in MDA-MB-231 cells and identified differentially expressed genes in SM-164-resistant and -sensitive MDA-MB-231 cells. SCID mice with MDA-MB-231 xenograft tumors were treated with 5 mg/kg of SM-164 intravenously for 5 days/week for 2 weeks. SM-164-regressed MDA-MB-231 tumors regrew after treatment ended. Tumor cells from these regrown MDA-MB-231 tumors were isolated and total RNAs were prepared for microarray analysis.

CD137 (4-1BB) requires physically associated cIAPs for signal transduction and antitumor effects

Project description:CD137 (4-1BB) is a member of the TNFR family that mediates potent T-cell costimulatory signals upon ligation by CD137L or agonist monoclonal antibodies. CD137 agonists attain immunotherapeutic antitumor effects in cancer mouse models and multiple agents of this kind are undergoing clinical trials. We show that cIAP1 and cIAP2 are physically associated with the CD137-signaling complex. Moreover, cIAPs are required for CD137 signaling towards the NF-κB and MAPK pathways and for costimulation of human and mouse T lymphocytes. Functional evidence was substantiated with SMAC-mimetics that trigger cIAPs degradation and by transfecting cIAP dominant-negative variants. Antitumor effects of agonist anti-CD137 mAbs are critically dependent on the integrity of cIAPs in cancer mouse models and cIAPs are also required for signaling from CARs encompassing CD137’s cytoplasmic tail.

Antagonism of IAPs enhances CAR T cell efficacy

Project description:Chimeric antigen receptor (CAR) T cell therapy has proven highly successful in the treatment of hematological malignancies, notably acute lymphoblastic leukemia and B cell lymphoma. However, the efficacy of CAR T cells against solid tumors is poor, likely due to tumor-associated immunosuppression. Here, we demonstrate that antagonizing Inhibitor of Apoptosis Proteins (IAPs) with the clinical smac-mimetic, birinapant, significantly enhanced the anti-tumor activity of CAR T cells in a TNF-dependent manner. Enhanced tumor cell death occurred independently of the perforin-mediated granule exocytosis pathway, underscoring the cytotoxic potential of CAR T cell-derived TNF. Importantly, combining CAR T cell therapy with birinapant dramatically reduced established tumor growth in vivo, where either therapy alone was relatively ineffective. Using patient biopsy-derived tumoroids, we demonstrate the synergistic potential of combining CAR T cell therapy with smac-mimetics. Taken together, we identify CAR T cell-derived TNF as a potent anti-tumor effector, which can be further harnessed by smac-mimetics.

Expression Profiling of Heart (NH, TAC and TAC-R)

Project description:Transcriptome analysis of RNA samples from whole heart Transverse aortic constriction (TAC) is a well-established method for studying the pathomechanisms of heart failure in animal models of cardiac hypertrophy. A number of studies have shown that the treatment of heart failure in this animal model of cardiac hypertrophy suggests that hypertrophy and fibrosis may be reversible. However, since TAC-release protocols that improve hemodynamics by releasing physical stenosis remain undefined, the histological characteristics and molecular biological regulatory mechanisms of the reversibility of cardiac hypertrophy and fibrosis are unknown. Therefore, this study aimed to establish a TAC release model and investigate the reversibility and plasticity mechanisms of myocardial hypertrophy, fibrosis, and angiogenesis. Four weeks post-TAC surgery, TAC release was conducted by cutting the aortic stenosis sutures. The TAC group exhibited severe myocardial hypertrophy, fibrosis, and increased angiogenesis, along with diastolic dysfunction. Conversely, the TAC-release group showed reduced hypertrophy and fibrosis, and improved diastolic function. Gene expression analysis highlighted Regulator of Calcineurin 1 as a key player in cardiac function and histological changes post-TAC release. Rcan1 knockdown exacerbated myocardial hypertrophy and fibrosis in the TAC-release group. This study sheds light on the functional, structural, and histological changes in the heart induced by TAC release and elucidates some of its regulatory mechanisms.
