AbstractBrahma‐related gene 1 (Brg‐1) is perceived as a cytoprotective protein due to its role in alleviating oxidative stress and apoptosis. Our study aimed to explore the role and mechanism of Brg‐1 in high glucose (HG)‐stimulated podocytes. The HG exposure downregulated Brg‐1 and inactivated the protein kinase B (Akt) pathway in podocytes. Restoration of Brg‐1 inhibited HG‐induced viability reduction of podocytes. The HG‐induced increase of reactive oxygen species and malondialdehyde levels and decrease of superoxide dismutase activity in podocytes were reversed by the Brg‐1 overexpression. The Brg‐1 overexpression terminated the HG‐induced production of fibronectin, collagen IV, transforming growth factor‐β1, and connective tissue growth factor. In addition, the Brg‐1 overexpression activated Akt‐dependent nuclear factor E2‐related factor 2 (Nrf2)/antioxidant response element (ARE) signaling in HG‐stimulated podocytes. However, inhibition of the Akt pathway or Nrf2 silencing counteracted the protective effects of Brg‐1 in HG‐stimulated podocytes. In conclusion, the Brg‐1 overexpression suppressed HG‐induced oxidative stress and extracellular matrix accumulation by activation of Akt‐dependent Nrf2/ARE signaling in podocytes.

The evolutionarily conserved SWI-SNF chromatin remodeling complex regulates cellular proliferation. A catalytic subunit, BRG-1, is frequently down regulated, silenced or mutated in malignant cells, however, the mechanism by which BRG-1 may function as a tumor suppressor or block breast cancer cellular proliferation is not understood. The cyclin D1 gene is a collaborative oncogene overexpressed in greater than 50% of human breast cancers. Herein, BRG-1 inhibited DNA synthesis and cyclin D1 expression in human MCF-7 breast cancer epithelial cells. The cyclin D1 promoter AP-1 and CRE sites were required for repression by BRG-1 in promoter assays. BRG-1 deficient cells abolished and siRNA to BRG-1 reduced, formation of the BRG-1 chromatin complex. The endogenous cyclin D1 promoter AP-1 site bound BRG-1. Estradiol treatment of MCF-7 cells induced recruitment of BRG-1 to the endogenous hpS2 gene promoter. Estradiol, which induced cyclin D1 abundance, was associated with a reduction in recruitment of the co-repressors HP1alpha/HDAC1 to the endogenous cyclin D1 promoter AP-1/BRG-1 binding sites. These studies suggest the endogenous cyclin D1 promoter BRG-1 binding site functions as a molecular scaffold in the context of local chromatin upon which coactivators and corepressors are recruited to regulate cyclin D1.

Roles of Brahma and Brahma/SWI2-Related Gene 1 in Hypoxic Induction of the Erythropoietin Gene

Article

作者: Christian Muchardt ; Oliver Hankinson ; Moshe Yaniv ; Ruixue Zhang ; Timothy V. Beischlag ; Feng Wang

Upon hypoxia, the human erythropoietin (EPO) gene is transactivated by the heterodimeric hypoxia-inducible factor 1 (HIF-1). Mammalian SWI/SNF is a chromatin-remodeling complex involved in the modulation of gene expression. We demonstrate that Brahma (Brm) and Brahma/SWI2-related gene 1 (Brg-1), alternative ATPase subunits of SWI/SNF, potentiate reporter gene activation mediated by HIF-1 in an ATPase-dependent manner. Brm was more potent than Brg-1 in the reporter gene assays. Simultaneous depletion of both Brm and Brg-1 by small interfering RNAs significantly compromised the transcription of the endogenous EPO gene triggered by hypoxia. Whereas knocking down Brm alone resulted in a moderate reduction in transcription of the EPO gene, depletion of Brg-1 resulted in an augmentation of transcription of both the EPO gene and the Brm gene, indicating that Brm can compensate for loss of Brg-1. Chromatin immunoprecipitation (ChIP) and sequential ChIP (re-ChIP) analysis showed that both Brm and Brg-1 associate with the enhancer region of the EPO gene in vivo in a hypoxia-dependent fashion and that each is present in a complex with HIF-1. Brm and Brg-1 were also recruited to the promoter of the vascular endothelial growth factor (VEGF) gene in a hypoxia-dependent fashion, although hypoxic induction of VEGF transcription was not affected by depletions of either or both Brm and Brg-1. Together these studies reveal a novel role for SWI/SNF in the activation of transcription of the EPO gene, indicate an important communication and compensation between Brm and Brg-1, and suggest that the requirement for SWI/SNF during hypoxic induction is gene-specific.

Biosyngen Best-in-Class Next-Generation Tumor-Infiltrating Lymphocyte (TIL) Technology Debuts on ESMO 2024 Annual Meeting

BARCELONA, Spain, Sept. 20, 2024 /PRNewswire/ -- The highly anticipated 2024 European Society for Medical Oncology (ESMO) Annual Congress has taken place from September 13 to 17 in Barcelona, Spain. As one of the most influential annual gatherings in oncology, this congress brings together leading cancer experts and researchers from around the globe, showcasing the latest advancements in the field and providing high-quality educational and networking opportunities for oncology professionals. Continue Reading Figure 1 BSGTIL antitumor efficacy Biosyngen, an innovative biotechnology company specializing in immune cell therapies, has showcased its groundbreaking technology on gene-modified, functionally enhanced tumor-infiltrating lymphocytes (TILs) derived from liver cancer biopsy samples. BioSyngen has secured ten clinical trial approvals in China and the U.S. for its innovative fourth-generation oncology therapies. Currently, our leading pipeline product, BRG01, is in the pivotal Phase II clinical trial stage for solid tumors. Additionally, the first patients have been enrolled in the Phase I trials for our other groundbreaking therapies, BST02 and BRL03, with completion of Phase I trials anticipated later this year. Abstract Title Pre-clinical Development of Genetically Modified Tumor-infiltrating Lymphocytes using Biopsy Samples from Liver Cancer Patients Abstract No. 1034P Tumor-infiltrating lymphocytes (TILs) are heterogeneous lymphocyte populations within the tumor microenvironment that contains T cells capable of recognizing tumor- or virus-associated antigens. In February of this year, the FDA approved the first TIL-based therapy used with IL-2 for advanced metastatic/recurrent melanoma. However, due to the variability in T cell infiltration between hot and cold tumors, differential abundance of antigen-specific T cells with robust immune response functionality, and the dependence of TIL anti-tumor efficacy on concomitant use of high-dose IL-2 combination therapy, the therapeutic applications of non-edited TILs are quite limited outside of melanoma. To address these challenges, Biosyngen has developed a proprietary platform for expanding TILs from biopsy samples, achieving production of 1011 cells within four weeks. Additionally, the company has established a stable gene modification platform that reprograms TIL metabolism, enhances TIL activity and sustained antitumor efficacy by expressing membrane anchor proteins. Anti-tumor efficacy has significantly enhanced (without IL-2 co-injection) and no obvious toxicity observed. Biosyngen houses best-in-class proprietary TIL platform aiming to expand the clinical applications of TIL technology with following features: Efficient Automated TILs Manufacturing System: Pioneering the use of tumor biopsy samples for TIL preparation with the ability to cryopreserve both tumor tissue and final products, overcoming logistical constraints. Effective In Vitro Gene-engineering System: Employs viral vector technology for stable gene modification, maintaining high gene expression efficiency in TILs. Enhanced In Vivo Expansion and Persistence: Increased proportion of central memory T cells (TCM) in the final product, leading to prolonged persistence. Powerful Antitumor Efficacy: Demonstrates strong tumor-killing effects without the need for concomitant use of IL-2.
