3-Methyladenine but not antioxidants to overcome BACH2-mediated bortezomib resistance in mantle cell lymphoma.

Cancer Cell Int 2021 May 26;21(1):279. Epub 2021 May 26.

Institute of Medical Biology, Chinese Academy of Medical Sciences and Peking Union Medical College, 935 Jiaoling Road, Kunming, 650118, Yunnan, China.

Background: Bortezomib (BTZ) is an inhibitor of the proteasome that has been used to treat patients with mantle cell lymphoma (MCL), but the resistance to BTZ in clinical cases remains a major drawback. BACH2 is a lymphoid-specific transcription repressor recognized as a tumor suppressor in MCL. Reduced BACH2 levels contribute to BTZ resistance; however, the molecular events underlying BACH2-mediated BTZ resistance are largely unclear. Read More

The Keap1-Nrf2 System: A Mediator between Oxidative Stress and Aging.

Oxid Med Cell Longev 2021 19;2021:6635460. Epub 2021 Apr 19.

Zunyi Municipal Key Laboratory of Medicinal Biotechnology, Affiliated Hospital of Zunyi Medical University, 149 Dalian Road, Huichuan District, Zunyi 563003, China.

Oxidative stress, a term that describes the imbalance between oxidants and antioxidants, leads to the disruption of redox signals and causes molecular damage. Increased oxidative stress from diverse sources has been implicated in most senescence-related diseases and in aging itself. The Kelch-like ECH-associated protein 1- (Keap1-) nuclear factor-erythroid 2-related factor 2 (Nrf2) system can be used to monitor oxidative stress; Keap1-Nrf2 is closely associated with aging and controls the transcription of multiple antioxidant enzymes.

Therapeutic effect of co-culture of rat bone marrow mesenchymal stem cells and degenerated nucleus pulposus cells on intervertebral disc degeneration.

Spine J 2021 May 14. Epub 2021 May 14.

Thoracic Lumbar Spine Surgery, The Second Affiliated Hospital of Inner Mongolia Medical University.

Background: After non-contact co-culture of bone marrow mesenchymal stem cells (BMSCs) with nucleus pulposus cells (NPCs), exosomes secreted by BMSCs were able to ameliorate the degree of disc degeneration. The reason for this is, at least in part, that exosomes from BMSCs achieve by affecting the level of autophagy in NPCs, while the components in exosomes are diverse and their specific mechanism of action is still unclear.

Purpose: Here, we aimed to explore the therapeutic effect of co-culture of bone marrow mesenchymal stem cells (BMSCs) and nucleus pulposus cells (NPCs) on degenerated nucleus pulposus cells and explore its specific mechanism of action. Read More

Limited inhibition of multiple nodes in a driver network blocks metastasis.

Elife 2021 May 11;10. Epub 2021 May 11.

Ben May Department for Cancer Research, University of Chicago, Chicago, United States.

Metastasis suppression by high-dose, multi-drug targeting is unsuccessful due to network heterogeneity and compensatory network activation. Here, we show that targeting driver network signaling capacity by limited inhibition of core pathways is a more effective anti-metastatic strategy. This principle underlies the action of a physiological metastasis suppressor, Raf Kinase Inhibitory Protein (RKIP), that moderately decreases stress-regulated MAP kinase network activity, reducing output to transcription factors such as pro-metastastic BACH1 and motility-related target genes.

Challenges and Limitations of Targeting the Keap1-Nrf2 Pathway for Neurotherapeutics: Bach1 De-Repression to the Rescue.

Front Aging Neurosci 2021 8;13:673205. Epub 2021 Apr 8.

Darby Children's Research Institute, Medical University of South Carolina, Charleston, SC, United States.

The Keap1-Nrf2 signaling axis is a validated and promising target for cellular defense and survival pathways. This minireview discusses the potential off-target effects and their impact on future drug development originating from Keap1-targeting small molecules that function as displacement activators of the redox-sensitive transcription factor Nrf2. We argue that small-molecule displacement activators, similarly to electrophiles, will release both Nrf2 and other Keap1 client proteins from the ubiquitin ligase complex. Read More

Heme Oxygenase-1 Contributes to Both the Engulfment and the Anti-Inflammatory Program of Macrophages during Efferocytosis.

Cells 2021 Mar 15;10(3). Epub 2021 Mar 15.

Section of Dental Biochemistry, Department of Biochemistry and Molecular Biology, Faculty of Dentistry, University of Debrecen, 4012 Debrecen, Hungary.

Heme oxygenase-1 (HO-1) plays a vital role in the catabolism of heme and yields equimolar amounts of biliverdin, carbon monoxide, and free iron. We report that macrophages engulfing either the low amount of heme-containing apoptotic thymocytes or the high amount of heme-containing eryptotic red blood cells (eRBCs) strongly upregulate HO-1. The induction by apoptotic thymocytes is dependent on soluble signals, which do not include adenylate cyclase activators but induce the p38 mitogen-activated protein (MAP) kinase pathway, while in the case of eRBCs, it is cell uptake-dependent.

Comprehensive Mutational Analysis of the BRCA1-Associated DNA Helicase and Tumor-Suppressor FANCJ/BACH1/BRIP1.

Mol Cancer Res 2021 Jun 22;19(6):1015-1025. Epub 2021 Feb 22.

Department of Molecular Cell and Cancer Biology, University of Massachusetts Medical School, Worcester, Massachusetts.

FANCJ (BRIP1/BACH1) is a hereditary breast and ovarian cancer (HBOC) gene encoding a DNA helicase. Similar to HBOC genes, BRCA1 and BRCA2, FANCJ is critical for processing DNA inter-strand crosslinks (ICL) induced by chemotherapeutics, such as cisplatin. Consequently, cells deficient in FANCJ or its catalytic activity are sensitive to ICL-inducing agents. Read More

PDLIM2 repression by ROS in alveolar macrophages promotes lung tumorigenesis.

JCI Insight 2021 Mar 8;6(5). Epub 2021 Mar 8.

UPMC Hillman Cancer Center, Pittsburgh, Pennsylvania, USA.

One of the most fundamental and challenging questions in the field of cancer is how immunity is transformed from tumor immunosurveillance to tumor-promoting inflammation. Here, we identified the tumor suppressor PDZ-LIM domain-containing protein 2 (PDLIM2) as a checkpoint of alveolar macrophages (AMs) important for lung tumor suppression. During lung tumorigenesis, PDLIM2 expression in AMs is downregulated by ROS-activated transcription repressor BTB and CNC homology 1 (BACH1). Read More

BACH1 recruits NANOG and histone H3 lysine 4 methyltransferase MLL/SET1 complexes to regulate enhancer-promoter activity and maintains pluripotency.

Nucleic Acids Res 2021 02;49(4):1972-1986

Department of Physiology and Pathophysiology, School of Basic Medical Sciences, Shanghai Key Laboratory of Bioactive Small Molecules; Institutes of Biomedical Sciences, Fudan University, Shanghai 200032, China.

Maintenance of stem-cell identity requires proper regulation of enhancer activity. Both transcription factors OCT4/SOX2/NANOG and histone methyltransferase complexes MLL/SET1 were shown to regulate enhancer activity, but how they are regulated in embryonic stem cells (ESCs) remains further studies. Here, we report a transcription factor BACH1, which directly interacts with OCT4/SOX2/NANOG (OSN) and MLL/SET1 methyltransferase complexes and maintains pluripotency in mouse ESCs (mESCs). Read More

Age-related alteration in HNE elimination enzymes.

Arch Biochem Biophys 2021 03 5;699:108749. Epub 2021 Jan 5.

Leonard Davis School of Gerontology, University of Southern California, 3715 McClintock Avenue, Los Angeles, CA, 90089, United States. Electronic address:

4-hydroxynonenal (HNE, 4-hydroxy-2-nonenal) is a primary α,β-unsaturated aldehyde product of lipid peroxidation. The accumulation of HNE increases with aging and the mechanisms are mainly attributable to increased oxidative stress and decreased capacity of HNE elimination. In this review article, we summarize the studies on age-related change of HNE concentration and alteration of HNE metabolizing enzymes (GCL, GST, ALDHs, aldose reductase, and 20S-proteasome), and discuss potential mechanism of age-related decrease in HNE-elimination capacity by focusing on Nrf2 redox signaling.
