Identifying and validating potential therapeutic targets for septic heart failure and the cardioprotective effects of lycorine. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 129:155677. [PMID: 38678951 DOI: 10.1016/j.phymed.2024.155677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 03/28/2024] [Accepted: 04/22/2024] [Indexed: 05/01/2024]
Abstract
BACKGROUND Septic heart failure has been recognized as a puzzle since antiquity and poses a major challenge to modern medicine. Our previous work has demonstrated the potential effects of lycorine (LYC) on sepsis and septic myocardial injury. Nonetheless, further exploration is needed to elucidate the underlying cellular and molecular mechanisms. METHODS In this study, we conducted transcriptome analysis and weighted gene co-expression network analysis (WGCNA) to identify the key genes and reveal the mechanism of LYC against septic heart failure. PURPOSE This study aims to apply bioinformatic analysis and experimental validations to explore the protective effects and underlying mechanism of LYC on the cecal ligation and puncture (CLP)-induced sepsis model mice. RESULTS Transcriptome analysis revealed the differentially expressed genes (DEGs) following LYC treatment. WGCNA analysis identified gene modules associated with LYC-mediated protection, with BCL3 emerging as a core gene within these modules. Notably, BCL3 was an overlapping gene of DEGs and WGCNA core genes induced by LYC treatment, and is highly negatively correlated with cardiac function indicator. In vivo and in vitro study further prove that LYC exerted a protective effect against septic myocardial injury through inhibiting BCL3. BCL3 siRNA ameliorated LPS-induced cardiac injury and inflammation, while BCL3 overexpression reversed the protective effect of LYC against LPS injury. CONCLUSION In summary, our findings demonstrate the significant attenuation of septic myocardial disorder by LYC, with the identification of BCL3 as a pivotal target gene. This study is the first to report the role of BCL3 in sepsis and septic myocardial injury. Furthermore, the strategy for hub genes screening used in our study facilitates a comprehensive exploration of septic targets and reveals the potential targets for LYC effect. These findings may offer a new therapeutic strategy for the management of septic heart failure, highlighting the cardioprotective effect of LYC as adjunctive therapy for sepsis management.

Abstract
Atherosclerotic cardiovascular disease (ASCVD) has become the leading cause of death worldwide, and early diagnosis and treatment of atherosclerosis (AS) are crucial for reducing the occurrence of acute cardiovascular events. However, early diagnosis of AS is challenging, and oral anti-AS drugs suffer from limitations like imprecise targeting and low bioavailability. To overcome the aforementioned shortcomings, Cur/MOF@DS is developed, a nanoplatform integrating diagnosis and treatment by loading curcumin (Cur) into metal-organic frameworks with nanozymes and magnetic resonance imaging (MRI) properties. In addition, the surface-modification of dextran sulfate (DS) enables PCN-222(Mn) effectively target scavenger receptor class A in macrophages or foam cells within the plaque region. This nanoplatform employs mechanisms that effectively scavenge excessive reactive oxygen species in the plaque microenvironment, promote macrophage autophagy and regulate macrophage polarization to realize lipid regulation. In vivo and in vitro experiments confirm that this nanoplatform has outstanding MRI performance and anti-AS effects, which may provide a new option for early diagnosis and treatment of AS.

J Exp Clin Cancer Res 2024; 43:117. [PMID: 38641672 PMCID: PMC11027350 DOI: 10.1186/s13046-024-03036-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Accepted: 04/02/2024] [Indexed: 04/21/2024] Open
Abstract
BACKGROUND Cholangiocarcinoma (CCA) is a highly malignant cancer of the biliary tract with poor prognosis. Further mechanistic insights into the molecular mechanisms of CCA are needed to develop more effective target therapy. METHODS The expression of the histone lysine acetyltransferase KAT2B in human CCA was analyzed in human CCA tissues. CCA xenograft was developed by inoculation of human CCA cells with or without KAT2B overexpression into SCID mice. Western blotting, ChIP-qPCR, qRT-PCR, protein immunoprecipitation, GST pull-down and RNA-seq were performed to delineate KAT2B mechanisms of action in CCA. RESULTS We identified KAT2B as a frequently downregulated histone acetyltransferase in human CCA. Downregulation of KAT2B was significantly associated with CCA disease progression and poor prognosis of CCA patients. The reduction of KAT2B expression in human CCA was attributed to gene copy number loss. In experimental systems, we demonstrated that overexpression of KAT2B suppressed CCA cell proliferation and colony formation in vitro and inhibits CCA growth in mice. Mechanistically, forced overexpression of KAT2B enhanced the expression of the tumor suppressor gene NF2, which is independent of its histone acetyltransferase activity. We showed that KAT2B was recruited to the promoter region of the NF2 gene via interaction with the transcription factor SP1, which led to enhanced transcription of the NF2 gene. KAT2B-induced NF2 resulted in subsequent inhibition of YAP activity, as reflected by reduced nuclear accumulation of oncogenic YAP and inhibition of YAP downstream genes. Depletion of NF2 was able to reverse KAT2B-induced reduction of nuclear YAP and subvert KAT2B-induced inhibition of CCA cell growth. CONCLUSIONS This study provides the first evidence for an important tumor inhibitory effect of KAT2B in CCA through regulation of NF2-YAP signaling and suggests that this signaling cascade may be therapeutically targeted for CCA treatment.

Abstract
Osteoarthritis (OA) is the most common chronic degenerative joint disease in middle-aged and elderly people, characterized by joint pain and dysfunction. Macrophages are key players in OA pathology, and their activation state has been studied extensively. Various studies have suggested that macrophages might respond to stimuli in their microenvironment by changing their phenotypes to pro-inflammatory or anti-inflammatory phenotypes, which is called macrophage polarization. Macrophages accumulate and become polarized (M1 or M2) in many tissues, such as synovium, adipose tissue, bone marrow, and bone mesenchymal tissues in joints, while resident macrophages as well as other stromal cells, including fibroblasts, chondrocytes, and osteoblasts, form the joint and function as an integrated unit. In this study, we focus exclusively on synovial macrophages, adipose tissue macrophages, and osteoclasts, to investigate their roles in the development of OA. We review recent key findings related to macrophage polarization and OA, including pathogenesis, molecular pathways, and therapeutics. We summarize several signaling pathways in macrophage reprogramming related to OA, including NF-κB, MAPK, TGF-β, JAK/STAT, PI3K/Akt/mTOR, and NLRP3. Of note, despite the increasing availability of treatments for osteoarthritis, like intra-articular injections, surgery, and cellular therapy, the demand for more effective clinical therapies has remained steady. Therefore, we also describe the current prospective therapeutic methods that deem macrophage polarization to be a therapeutic target, including physical stimulus, chemical compounds, and biological molecules, to enhance cartilage repair and alleviate the progression of OA.
