Ferroptosis is a non-apoptotic form of regulated cell death characterized by the lethal accumulation of iron-dependent membranelocalized lipid peroxides.It acts as an innate tumor suppressor mechanism and participates in the biological processes of tumors.Intriguingly,mesenchymal and dedifferentiated cancer cells,which are usually resistant to apoptosis and traditional therapies,are exquisitely vulnerable to ferroptosis,further underscoring its potential as a treatment approach for cancers,especially for refractory cancers.However,the impact of ferroptosis on cancer extends beyond its direct cytotoxic effect on tumor cells.Ferroptosis induction not only inhibits cancer but also promotes cancer development due to its potential negative impact on anticancer immunity.Thus,a comprehensive understanding of the role of ferroptosis in cancer is crucial for the successful translation of ferroptosis therapy from the laboratory to clinical applications.In this review,we provide an overview of the recent advancements in understanding ferroptosis in cancer,covering molecular mechanisms,biological functions,regulatory pathways,and interactions with the tumor microenvironment.We also summarize the potential applications of ferroptosis induction in immunotherapy,radiotherapy,and systemic therapy,as well as ferroptosis inhibition for cancer treatment in various conditions.We finally discuss ferroptosis markers,the current challenges and future directions of ferroptosis in the treatment of cancer.

Background:Genetic variants of dopaminergic transcription factor-encoding genes are suggested to be Parkinson’s disease(PD)risk factors;however,no comprehensive analyses of these genes in patients with PD have been undertaken.Therefore,we aimed to genetically analyze 16 dopaminergic transcription factor genes in Chinese patients with PD.Methods:Whole-exome sequencing(WES)was performed using a Chinese cohort comprising 1917 unrelated patients with familial or sporadic early-onset PD and 1652 controls.Additionally,whole-genome sequencing(WGS)was performed using another Chinese cohort comprising 1962 unrelated patients with sporadic late-onset PD and 1279 controls.Results:We detected 308 rare and 208 rare protein-altering variants in the WES and WGS cohorts,respectively.Gene-based association analyses of rare variants suggested that MSX1 is enriched in sporadic late-onset PD.However,the significance did not pass the Bonferroni correction.Meanwhile,72 and 1730 common variants were found in the WES and WGS cohorts,respectively.Unfortunately,single-variant logistic association analyses did not identify significant associations between common variants and PD.Conclusions:Variants of 16 typical dopaminergic transcription factors might not be major genetic risk factors for PD in Chinese patients.However,we highlight the complexity of PD and the need for extensive research elucidating its etiology.

Valvular heart disease(VHD),clinically manifested as stenosis and regurgitation of native heart valve,is one of the most prevalent cardiovascular diseases with high mortality.Heart valve replacement surgery has been recognized as golden standard for the treatment of VHD.Owing to the clinical application of transcatheter heart valve replacement technic and the excellent hemodynamic performance of bioprosthetic heart valves(BHVs),implantation of BHVs has been increasing over recent years and gradually became the preferred choice for the treatment of VHD.However,BHVs might fail within 10-15 years due to structural valvular degeneration(SVD),which was greatly associated with drawbacks of glutaraldehyde crosslinked BHVs,including cytotoxicity,calcification,component degradation,mechanical failure,thrombosis and immune response.To prolong the service life of BHVs,much effort has been devoted to overcoming the drawbacks of BHVs and reducing the risk of SVD.In this review,we summarized and analyzed the research and progress on:(i)modification strategies based on glutaraldehyde crosslinked BHVs and(ii)nonglutaraldehyde crosslinking strategies for BHVs.

Inhibition of mycobacterial membrane protein large 3(MmpL3)thereby affecting the mycolic acid biosynthetic pathway has been proven to be an effective strategy for developing antitubercular drugs.Based on the X-ray crystal structure of MmpL3 inhibitor complexes,a series of novel 1,2,4-triazole derivatives were designed,synthesized and evaluated antitubercular activity against Mtb strain H37Rv.Comprehensive structure–activity relationship exploration resulted in the identification of compounds 21 and 28,which possess potent antitubercular activity against Mtb strain H37Rv[minimum inhibitory concentration(MIC)=0.03–0.13μg/mL]and the clinical isolates of multidrug resistance(MDR)and extensive drug resistance(XDR)tuberculosis(MIC=0.06–1.0μg/mL).Moreover,compounds 21 and 28 showed neglectable cytotoxicity(IC_(50)≥32μg/mL)to the mammalian Vero cells and favorable physicochemical and pharmacokinetic properties according to the in silico absorption,distribution,metabolism and excretion(ADME)prediction.Finally,the potential target of representative 1,2,4-triazole 28 was identified to be MmpL3 using a microscale thermophoresis(MST)assay.

Vertebrate life begins with fertilization,and then the zygote genome is activated after transient silencing,a process termed zygotic genome activation(ZGA).Despite its fundamental role in totipotency and the initiation of life,the precise mechanism underlying ZGA initiation remains unclear.The existence of minor ZGA implies the possible critical role of noncoding RNAs in the initiation of ZGA.Here,we delineate the expression profile of long noncoding RNAs(lncRNAs)in early mouse embryonic development and elucidate their critical role in minor ZGA.Compared with protein-coding genes(PCGs),lncRNAs exhibit a stronger correlation with minor ZGA.Distinct H3K9me3 profiles can be observed between lncRNA genes and PCGs,and the enrichment of H3K9me3 before ZGA might explain the suspended expression of major ZGA-related PCGs despite possessing PolII pre-configuration.Furthermore,we identified the presence of PolII-enriched MuERV-L around the transcriptional start site of minor ZGA-related lncRNAs,and these repeats are responsible for the activation of minor ZGA-related lncRNAs and subsequent embryo development.Our study suggests that MuERV-L mediates minor ZGA lncRNA activation as a critical driver between epigenetic reprogramming triggered by fertilization and the embryo developmental program,thus providing clues for understanding the regulatory mechanism of totipotency and establishing bona fide totipotent stem cells.

Sulforaphane, a naturally specialized metabolite, plays significant roles in human disease prevention and plant defense. Myrosinase(MY) is a key gene responsible for the catalysis of sulforaphane formation, but the molecular mechanisms through which MY regulates sulforaphane biosynthesis in plants remains largely unknown. Here, we discovered that the change of sulforaphane content in broccoli sprouts caused by exogenous selenite treatments is positively related to BoMY expression. BoMY overexpression in the Arabidopsis thaliana tgg1 mutants could dramatically increase myrosinase activity and sulforaphane content in the rosette leaves of 35S::BoMY/tgg1 and rescue its phenotypes.Moreover, an obvious increase of myrosinase activity and sulforaphane content was displayed in transgenic BoMY-overexpressed broccoli lines.In addition, a 2 033 bp promoter fragment of BoMY was isolated. Yeast one-hybrid(Y1H) library screening experiment uncovered that one bHLH transcription factor, BoFAMA, could directly bind to BoMY promoter to activate its expression, which was further evidenced by Y1H assay and dual-luciferase reporter assay. BoFAMA is a selenite-responsive transcription factor that is highly expressed in broccoli leaves;its protein is solely localized to nucleus. Additionally, genetic evidence suggested that the knockdown of FAMA gene in Arabidopsis thaliana could significantly decrease sulforaphane yield by inhibiting the expression of myrosinase genes. Interestingly, exogenous selenite supply could partially restore the low level of sulforaphane content in transgenic Arabidopsis FAMA-silencing plants. Our findings uncover a novel function of FAMAMY module in the regulation of selenite-mediated sulforaphane synthesis and provide a new insights into the molecular mechanism by which selenite regulates the accumulation of sulforaphane in plants.

Lactate is present at a high level in the microenvironment of mammalian preimplantation embryos in vivo and in vitro. However, its role in preimplantation development is unclear. Here, we report that lactate is highly enriched in the nuclei of early embryos when major zygotic genome activation(ZGA) occurs in humans and mice. The inhibition of its production and uptake results in developmental arrest at the 2-cell stage, major ZGA failure, and loss of lactate-derived H3K18lac, which could be rescued by the addition of Lac-Co A and recapitulated by overexpression of H3K18R mutation. By profiling the landscape of H3K18lac during mouse preimplantation development, we show that H3K18lac is enriched on the promoter regions of most major ZGA genes and correlates with their expressions. In humans, H3K18lac is also enriched in ZGA markers and temporally concomitant with their expressions. Taken together, we profile the landscapes of H3K18lac in mouse and human preimplantation embryos, and demonstrate the important role for H3K18lac in major ZGA, showing that a conserved metabolic mechanism underlies preimplantation development of mammalian embryos.

With over a million cases detected each year,skin disease is a global public health problem that diminishes the quality of life due to its difficulty to eradicate,propensity for recurrence,and potential for post-treatment scarring.Photodynamic therapy(PDT)is a treatment with minimal invasiveness or scarring and few side effects,making it well tolerated by patients.However,this treatment requires further research and development to improve its effective clinical use.Here,a piezoelectric-driven microneedle(PDMN)platform that achieves high efficiency,safety,and non-invasiveness for enhanced PDT is proposed.This platform induces deep tissue cavitation,increasing the level of protoporphyrin IX and significantly enhancing drug penetration.A clinical trial involving 25 patients with skin disease was conducted to investigate the timeliness and efficacy of PDMN-assisted PDT(PDMN-PDT).Our findings suggested that PDMN-PDT boosted treatment effectiveness and reduced the required incubation time and drug concentration by 25%and 50%,respectively,without any anesthesia compared to traditional PDT.These findings suggest that PDMN-PDT is a safe and minimally invasive approach for skin disease treatment,which may improve the therapeutic efficacy of topical medications and enable translation for future clinical applications.
