Boosting ferroptosis and microtubule inhibition for antitumor therapy via a carrier-free supermolecule nanoreactor / 药物分析学报

Traditional microtubule inhibitors fail to significantly enhance the effect of colorectal cancer;hence,new and efficient strategies are necessary.In this study,a supramolecular nanoreactor(DOC@TA-Fe3+)based on tannic acid(TA),iron ion(Fe3+),and docetaxel(DOC)with microtubule inhibition,reactive oxygen species(ROS)generation,and glutathione peroxidase 4(GPX4)inhibition,is prepared for ferroptosis/apoptosis treatment.After internalization by CT26 cells,the DOC@TA-Fe3+nanoreactor escapes from the lysosomes to release payloads.The subsequent Fe3+/Fe2+conversion mediated by TA reducibility can trigger the Fenton reaction to enhance the ROS concentration.Additionally,Fe3+can consume gluta-thione to repress the activity of GPX4 to induce ferroptosis.Meanwhile,the released DOC controls microtubule dynamics to activate the apoptosis pathway.The superior in vivo antitumor efficacy of DOC@TA-Fe3+nanoreactor in terms of tumor growth inhibition and improved survival is verified in CT26 tumor-bearing mouse model.Therefore,the nanoreactor can act as an effective apoptosis and ferroptosis inducer for application in colorectal cancer therapy.

Progress of hereditary breast cancer with breast cancer susceptibility gene 1/2 mutations / 肿瘤研究与临床

Hereditary breast cancer refers to malignant tumors caused by pathogenic germline mutations of breast cancer susceptibility genes (BRCA). At present, it is believed that BRCA1/2 genes are most closely related to the development of hereditary breast cancer. Mutation will lead to loss of normal function, instability of genome, and then lead to tumorigenesis. Especially for those with germline mutations, not only the risk of breast cancer will be greatly increased, but also the probability of ovarian cancer and other cancers will be increased. With the emergence and clinical application of poly (adenosine diphosphate-ribose) polymerase (PARP) inhibitors, BRCA1/2 genes have been regarded as new targets for the treatment of breast cancer. This article reviews the latest research of breast cancer with BRCA1/2 gene mutations.

Impact of LDB3 gene polymorphisms on clinical presentation and implantable cardioverter defibrillator (ICD) implantation in Chinese patients with idiopathic dilated cardiomyopathy / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

OBJECTIVE@#Mutations in LIM domain binding 3 (LDB3) gene cause idiopathic dilated cardiomyopathy (IDCM), a structural heart disease with a complicated genetic background. However, the association of polymorphisms in the LDB3 gene with susceptibility to IDCM in Chinese populations remains unexplored as dose the impact on clinical presentation.@*METHODS@#We sequenced all exons and the adjacent part of introns of the LDB3 gene in 159 Chinese Han IDCM patients and 247 healthy controls. Then we detected the distribution of polymorphisms in the LDB3 gene in all participants and assessed their associations with risk of IDCM. Additionally, we conducted a stratified genotype-phenotype correlation analysis.@*RESULTS@#The A allele of rs4468255 was significantly associated with IDCM (P<0.01). The rs4468255, rs11812601, rs56165849, and rs3740346 were also associated with diastolic blood pressure (DBP) and left ventricular ejection fraction (LVEF) (P<0.05). Notably, a higher frequency of rs4468255 polymorphism was observed in implantable cardioverter defibrillator (ICD) recipients under a recessive model (P<0.01), whereas the significant association disappeared after adjusting for potential confounders. However, in the dominant model, notable correlations could only be observed after adjusting for multi parameters.@*CONCLUSIONS@#The rs4468255 was significantly correlated with IDCM of Chinese Han population. A allele of rs4468255 is higher in IDCM patients with ICD implantation, suggesting the influence of genetic background in the generation of this response. In addition, rs11812601, rs56165849, and rs3740346 in LDB3 show association with brain natriuretic peptide, DBP, and LVEF levels in patients with IDCM but did not show any association with IDCM susceptibility.
