- NRF2 modulates tumor immune microenvironment in several cancers. NRF2 is activated in about 50% of high-grade serous ovarian cancer (HGSOC), the most aggressive type of ovarian cancer. Through analyzing data from scRNA-seq (n = 7), bulk RNA-seq (n = 365), and tumor microarray (TMA) of human HGSOC (n = 240) samples, we demonstrated that NRF2 expression correlated with tumor immune microenvironment in HGSOC. Functional pathway enrichment analysis and transcription factors (TFs) prediction showed the functional relevance of NRF2 expression in shaping the immune phenotype of HGSOC. Pathways such as hedgehog and ROS signaling, and TFs including EGR1, ESRRA, SMAD proteins, and SP-family proteins, are implicated in the immune suppressive microenvironment of NRF2 tumors. Immune differentiation analysis showed patients with NRF2 tumors enriched with CD68 have lower survival (p = 0.038) than those with CD68 tumors, whereas NRF2 tumors enriched with immune-activated markers such as CD3E and CD80 exhibit a better prognosis. This study is the first that shows classification of HGSOC based on NRF2 levels, highlights new biomarkers, and suggests IHC-labeling and genomic evaluation of NRF2 and immune markers for better prognosis. - Source: PubMed

Autophagy is an intracellular catabolic pathway involving lysosomal degradation and is closely associated with immunological pathways, effectively combating bacterial, viral, fungal, and parasitic infections. Accumulating evidence suggests that autophagy activation or inhibition by natural products promotes antimicrobial responses against various pathogens. Numerous natural products can modulate autophagy through diverse signaling pathways, suggesting their potential as a host-directed therapeutic strategy that may complement conventional drug regimens or help mitigate drug resistance in various infectious diseases. However, it remains largely unclear whether these effects are mediated by direct modulation of autophagy or indirectly through associated mechanisms, including enhanced immune defense, attenuation of pathological inflammation, or crosstalk with other organelle functions. Additionally, multiple pathogens can evade host responses; thus, autophagy activation may inadvertently create favorable conditions for certain pathogens. This review discusses the current knowledge of natural products in terms of their antimicrobial actions through autophagy regulation, particularly the roles of distinct natural product classes, such as polyphenols, alkaloids, terpenoids, quinones, peptides, and macrolides in modulating autophagy for potentially contributing to control various infectious diseases. Exploring the intricate molecular interplay between natural products and autophagy in limiting infections may provide valuable insights that could inform the development of innovative host-directed antimicrobial treatments based on autophagy regulation. 3-MA: 3-methyladenine; AM: alveolar macrophages; AMP: antimicrobial peptides; AMPK: 5' adenosine monophosphate-activated protein kinase; ARDS: acute respiratory distress syndrome; ART: artemisinin; ASFV: African swine fever virus; ATG: autophagy related; AZM: azithromycin; BafA1: bafilomycin A; BECN1: beclin 1; BMDM: bone marrow-derived macrophage; BNIP3: BCL2 interacting protein 3; BNIP3L: BCL2 interacting protein 3 like; CALCOCO2/NDP52: calcium binding and coiled-coil domain 2; CAMKK2: calcium/calmodulin-dependent protein kinase kinase 2; CBD: cannabidiol; CF: cystic fibrosis; CGA: chlorogenic acid; CGAS: cyclic GMP-AMP synthase; CHUK/IKKα: component of inhibitor of nuclear factor kappa B kinase complex; CLP: cecal ligation and puncture; CLR: clarithromycin; CMA: chaperone-mediated autophagy; CoV: coronavirus; DHT: dihydrotanshinone I; EGCG: epigallocatechin-3-gallate; EIF2A: eukaryotic translation initiation factor 2A; EIF2AK2: eukaryotic translation initiation factor 2 alpha kinase 2; ESKAPE: , and spp.; ESRRA: estrogen related receptor alpha; FOXO1: forkhead box O1; FUNDC1: FUN14 domain containing 1; HBV: hepatitis B virus; HCV: hepatitis C virus; HDT: host-directed therapy; HIV: human immunodeficiency virus; HMGB1: high mobility group box 1; HSV: herpes simplex virus; IAV: influenza A virus; ICT: isocryptotanshinone; IFN: interferon; IKBKB/IKKβ: inhibitor of nuclear factor kappa B kinase subunit beta; IL: interleukin; INH: isoniazid; IRF3: IFN regulatory factor 3; KEAP1: kelch like ECH associated protein 1; LAMP: lysosomal associated membrane protein; LAP: LC3-associated phagocytosis; LPS: lipopolysaccharide; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MAPK: mitogen-activated protein kinase; MDM: monocyte-derived macrophage; MDR: multidrug-resistant; MON: monotropein; Mtb: ; MTOR: mechanistic target of rapamycin kinase; mtROS: mitochondrial ROS; NET: neutrophil extracellular trap; NFE2L2/Nrf2: NFE2 like bZIP transcription factor 2; NFKB/NF-κB: nuclear factor kappa B; NLRP3: NLR family pyrin domain containing 3; NLRX1: NLR family member X1; NOTCH1: notch receptor 1; NTM: nontuberculous mycobacteria; OMS: ohmyungsamycin; PAK1: p21 (RAC1) activated kinase 1; PINK1: PTEN induced kinase 1; PKM/PKM2: pyruvate kinase M1/2; PLD: phospholipase D; PM: peritoneal macrophage; PPM1A: protein phosphatase, Mg2+/Mn2+ dependent 1A; PRKN/parkin: parkin RBR E3 ubiquitin protein ligase; PtdIns3K: phosphatidylinositol 3-kinase; PtdIns3P: phosphatidylinositol-3-phosphate; PTEN: phosphatase and tensin homolog; RB1CC1/FIP200: RB1 inducible coiled-coil 1; RELA/p65: RELA proto-oncogene, NF-kB subunit; RIF: rifampicin; ROS: reactive oxygen species; RSV: resveratrol; RUBCN/rubicon: rubicon autophagy regulator; SAR: selective autophagy receptor; SIRT: sirtuin; STING1: stimulator of interferon response cGAMP interactor 1; STX17: syntaxin 17; Tat: trans-activator of transcription; TB: tuberculosis; TBK1: TANK binding kinase 1; TFEB: transcription factor EB; TLR: toll like receptor; TNA: tanshinone IIA; TNF: tumor necrosis factor; UA: ursolic acid; ULK1/Atg1: unc-51 like autophagy activating kinase 1; UPR: unfolded protein response; UVRAG: UV radiation resistance associated; VAMP8: vesicle associated membrane protein 8; VDR: vitamin D receptor; WIPI2: WD repeat domain, phosphoinositide interacting 2; ZFYVE1/DFCP1: zinc finger FYVE-type containing 1; ZIKV: Zika virus. - Source: PubMed

Paik SeungwhaUm SoohyunKim In SooPark Eun-JinKim Kyung TaeBasu JoyotiOh Dong-ChanJo Eun-Kyeong - Acute kidney injury (AKI) is a clinically significant syndrome characterized by a rapid decline in renal function, affecting over 50% of patients in intensive care units. Ferroptosis, a recently identified form of regulated cell death, is driven by iron-dependent lipid peroxidation and has been implicated in AKI pathogenesis. Emerging evidence suggests that lipophagy - a selective autophagic degradation of lipid droplets - potentiates ferroptosis, though the upstream regulatory mechanisms remain poorly understood. ESRRA (estrogen related receptor, alpha), a key transcriptional regulator of fatty acid metabolism and macroautophagy/autophagy, may play a critical role in this process. In this study, we identified ESRRA as a pivotal transcription factor in proximal tubular epithelial cells using single-cell transcriptomic analysis. To investigate its functional role, we employed wild-type mice and tubular epithelial cell-specific deficient mice to establish AKI models. Our findings demonstrated that ESRRA exerted a protective effect by modulating the RAB7-dependent lipophagy-ferroptosis axis. Furthermore, integrating chromatin Immunoprecipitation (ChIP)-seq and JASPAR database analyses, we predicted as a direct transcriptional target of ESRRA. Mechanistically, ESRRA bind to a specific promoter region within , enhancing its expression and subsequently activating the AKT-MTOR signaling pathway, which is required for the suppression of RAB7 mediated lipophagy in renal tubular epithelial cells, thereby attenuating AKI progression. - Source: PubMed

Yuanting YangZhu XuyingFang YanLi JialinShao XinghuaLi ShuJin HaijiaoQi ChaojunLi ZhenyuanGu LeyiMou ShanLin QishengNi Zhaohui - The inflammation-intestinal metaplasia (IM)-carcinoma cascade has been proposed as a framework for gastric cancer (GC) development, yet the cell-level heterogeneity and microenvironmental remodeling underlying this progression remain poorly characterized. Here, we constructed a single-cell transcriptomic atlas by integrating scRNA-seq data from chronic gastritis (superficial, CGS), IM, cancer-adjacent, and tumor tissues through a unified analytical pipeline. Seven major cell lineages were resolved. Relative to CGS, IM and GC tissues exhibited a progressive contraction of epithelial compartments accompanied by expansion of immune and stromal populations. Copy number variation (CNV) inference identified two tumor-restricted malignant epithelial subgroups-one biased toward differentiation and the other enriched for inflammatory and epithelial-mesenchymal transition (EMT) signatures-as well as putative proto-malignant intermediates that coexisted with phenotypically normal epithelium. Cell-cell communication analysis indicated broadly augmented crosstalk between epithelial cells and T cells, myeloid cells, and fibroblasts, with prominent involvement of a CD44-extracellular matrix (ECM) axis. Pseudotime trajectory analysis placed malignant epithelium at late positions along gastric and pyloric mucosal cell differentiation backbones, coinciding with increasing CNV burden and enrichment of stem-like transcriptional programs. Gene regulatory network analysis revealed coordinated activity of lineage-specification modules (HNF4/CDX, NR1H4/ESRRA), proliferative regulons (MYC/TFDP1), and inflammatory/EMT-associated programs (FOSL1/REL/NF-κB). In independent cohorts, elevated expression of several malignant-epithelium-associated transcription factors-including HNF4A, KLF3, FOSL1, TCF7L2, BCL3, RELB, ONECUT2, and MAF-correlated with unfavorable overall survival. Collectively, these findings provide single-cell-resolution evidence consistent with the proposed three-stage model of gastric carcinogenesis and highlight candidate transcriptional regulators warranting further investigation as potential early-detection biomarkers. - Source: PubMed

Li XiulanGuo MengqiWen YunhanLong Bo - Fu brick tea (FT), known for regulating lipid metabolism, was studied to explore its lipid-lowering mechanism by analyzing its effects on gut microbes and adipose tissue. Mice were given chow, high-fat diet (HFD), or HFD + FT aqueous extract (FTE, 400 mg per kg BW). FTE reduced HFD-induced fat deposition, altered gut microbiota (enriched the "glycerolipid metabolism" pathway, reversed HFD-suppressed ), and affected epididymal fat transcriptome (genes enriched in PPAR, glycerolipid/fatty acid metabolism). Four lipid-related genes (, , , ) showed reversed expression patterns, while FTE treatment demonstrated no significant effects on adipocyte differentiation. FTE may exert lipid-lowering effects regulating gut microbe/adipose glycerolipid metabolism, with downstream metabolites playing a key role. In summary, FTE may alleviate lipid deposition by elevating to regulate dietary derived metabolites, which may enhance Esrra-mediated fatty acid oxidation-related gene expression, thereby improving triglyceride metabolism. Further studies are warranted to elucidate the specific roles and interactions of FTE's potential microbial and gene targets. - Source: PubMed
