- Atherosclerosis (AS) is a chronic inflammatory vascular disease that can lead to severe cardiovascular events. Ferroptosis and autophagy have been increasingly recognized for their significant roles in AS; however, few clinically translatable hub genes that connect these processes in atherosclerotic lesions have been identified. There is an urgent need for novel diagnostic and therapeutic targets to improve the early detection and intervention of AS. - Source: PubMed

Zheng XinouZheng JinlingLi XuezhuangChen HuaZhang LiZhao YuqiongLing Yahao - Natural products are biologically active compounds used for therapeutic interventions for various diseases, particularly infections. 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 - DHODH (dihydroorotate dehydrogenase (quinone)) has been demonstrated as a critical regulator of programmed cell death, yet its role in macroautophagy/autophagy remains poorly defined. pose a significant threat to global public health, and their replication is closely associated with autophagy. Building upon our previous findings that DHODH was a broad-spectrum target for and a key regulator of replication, this study employed RNA-seq screening coupled with functional validation to demonstrate that DHODH affected replication by regulating mitophagy. Notably, we observed remarkable virus genus specificity in this regulatory mechanism. For autophagy-dependent , DHODH deficiency impaired autophagosome-lysosome fusion, thereby suppressing viral replication. Conversely, in autophagy-inhibiting , the blockade of autophagy flux facilitated viral replication. These observations underscore the specificity of DHODH-mediated viral replication regulation. Additionally, compound supplementation assays indicated that DHODH regulated autophagy via pyrimidine nucleotide metabolism, as exogenous pyrimidine precursors restored autophagosome-lysosome fusion. Furthermore, our research uncovered a novel mechanism whereby classical swine fever virus (CSFV) non-structural protein 4A (NS4A) recruited DHODH to mitochondria, facilitating its interaction with MAP1LC3/LC3 (microtubule associated protein 1 light chain 3) through the LC3-interacting region (LIR) domain to activate mitophagy. Collectively, our findings highlight DHODH as a promising antiviral target within the metabolism-autophagy axis, providing novel insights for antiviral drug development.: AMPK: AMP-activated protein kinase; ATF4: activating transcription factor 4; ATG5: autophagy related 5; BafA1: bafilomycin A1; BNIP3L/NIX: BCL2 interacting protein 3 like; BVDV: bovine viral diarrhea virus; CALCOCO2/NDP52: calcium binding and coiled-coil domain 2; CCCP: carbonyl cyanide 3-chlorophenylhydrazone; co-IP: co-immunoprecipitation; COX4: cytochrome c oxidase subunit 4; CQ: chloroquine; CSFV: classical swine fever virus; DAPI: 4',6-diamidino-2-phenylindole; DEGs: differentially expressed genes; DHO: DHODH substrate dihydroorotate; DHODH: dihydroorotate dehydrogenase; DTMUV: duck tembusu virus; FIS1: fission mitochondrial 1; FUNDC1: FUN14 domain containing 1; GAPDH: glyceraldehyde-3-phosphate dehydrogenase; GFP: green fluorescent protein; GO: gene ontology; HSPA/HSP70: heat shock protein family A (Hsp70); JEV: Japanese encephalitis virus; KEGG: kyoto encyclopedia of genes and genomes; LIR: LC3-interacting region; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; Mdivi-1: mitochondrial division inhibitor 1; MFF: mitochondrial fission factor; MFN1: mitofusin 1; MFN2: mitofusin 2; MITO: mitochondria; MOI: multiplicity of infection; MTOR: mechanistic target of rapamycin kinase; MTS: mitochondrial targeting signal; OPTN: optineurin; ORO: DHODH product orotate; PBS: phosphate-buffered saline; PRKN: parkin RBR E3 ubiquitin protein ligase; PYR: pyrazofurin; RAPA: rapamycin; RFP: red fluorescent protein; RNA-seq: RNA sequencing; RT-qPCR: reverse transcription-quantitative real-time polymerase chain reaction; SD: standard deviation; siRNA: small interfering RNA; SQSTM1/p62: sequestosome 1; TOMM20: translocase of outer mitochondrial membrane 20; UMP: uridine monophosphate; VDAC1: voltage dependent anion channel 1. - Source: PubMed

Zhao BingqianChen JingCheng YanLi YuhangZhong LinhanChen JinxiaBi XiaoqingBai JishanDai QiYe YinboZou LinkeWang LiZhou Bin - PINK1 serves as the central regulator of PINK1-PRKN-mediated mitophagy, and its precise regulation is critical for efficient mitochondrial clearance. Although the cleavage of PINK1 and its subsequent degradation via the N-end rule pathway under basal conditions are well understood, how full-length PINK1 stability is regulated following mitochondrial damage has remained elusive. In our recent study, we identified the STUB1-VCP/p97 axis as a mechanism that fine-tunes full-length PINK1 levels during mitophagy. We demonstrate that STUB1 functions as an E3 ubiquitin ligase that catalyzes K48-linked polyubiquitination of full-length PINK1, which is subsequently recognized and extracted by VCP/p97 for proteasomal degradation. Disruption of this axis results in excessive accumulation of full-length PINK1, accelerated turnover of PRKN, and impaired mitophagy. Moreover, we find that this regulatory mechanism is compromised in the brains of patients with Alzheimer disease (AD), and its disruption leads to neuronal mitophagy defects and impaired associated learning capability in . These findings demonstrate that the STUB1-VCP/p97 complex fine-tunes PINK1 levels to ensure efficient mitophagy and preserve mitochondrial homeostasis.: AD, Alzheimer disease; CALCOCO2/NDP52, calcium binding and coiled-coil domain 2; MPP, mitochondrial processing peptidase; MQC, mitochondrial quality control; OMM, outer mitochondrial membrane; OPTN, optineurin; PARL, presenilin associated rhomboid like; PINK1, PTEN induced kinase 1; PRKN, parkin RBR E3 ubiquitin protein ligase; SILAC, stable isotope labeling by amino acids in cell culture; STUB1, STIP1 homology and U-box containing protein 1; TPR, tetratricopeptide repeat; VCP/p97, valosin containing protein; WIPI2, WD repeat domain, phosphoinositide interacting 2. - Source: PubMed

Lin Jin-YiHuang Ze-BoFang Evandro FLu Guang - Epilepsy and thyroid cancer are prevalent disorders with distinct etiologies; however, emerging evidence suggests the presence of shared molecular mechanisms that remain largely unexplored. In this study, we aimed to identify and characterize common hub genes and potential diagnostic markers linking these two conditions using comprehensive in silico and in vitro approaches. Differentially expressed genes (DEGs) were analyzed from epilepsy datasets (GSE44456, GSE186334) and thyroid cancer datasets (GSE60542, GSE153659), leading to the identification of four shared hub genes: CD44, CALCOCO2, ALDH4A1, and CLEC16A. Expression validation using RT-qPCR confirmed consistent patterns, with CD44 and CLEC16A significantly upregulated and CALCOCO2 and ALDH4A1 downregulated in disease cell lines compared to controls. Receiver operating characteristic (ROC) curve analysis demonstrated strong diagnostic potential for these genes in both diseases, with area under the curve (AUC) values exceeding 0.90. Functional enrichment and pathway analyses revealed that these genes are involved in oncogenic signaling, immune regulation, and tumor progression. Genetic alteration analysis indicated frequent mutations and copy number variations, while promoter methylation profiling suggested epigenetic regulation associated with disease outcomes. Survival analysis further identified ALDH4A1 and CLEC16A as prognostic markers. Moreover, in vitro and in vivo experiments demonstrated that CD44 and CLEC16A regulate cellular proliferation, migration, and clonogenicity through extracellular matrix (ECM)-receptor interactions involving CCL5, STAT3, CXCR4, and RAC1 signaling pathways. Collectively, these findings provide new insights into the shared molecular landscape of epilepsy and thyroid cancer, highlighting potential diagnostic biomarkers and therapeutic targets. - Source: PubMed
