BZDRs act on GABA type A receptors to inhibit neurotransmitters. We previously demonstrated that prolonged clinical use of BZDRs exacerbates the risk of breast cancer (BRCA).</p><p><strong>Methods: </strong>By biomedical, health informatics platform analyses and in vivo studies, we explored clinical association between BZDR usage and BRCA development and advancement. Furthermore, by retrospective studies on patient clinical data and in vitro empirical analyses of the impact of BZDR on BRCA cells, and together with ingenuity pathway analysis (IPA) analyses, we validated the signaling pathways and identified potential intermolecular crosstalk involved.</p><p><strong>Results: </strong>Clinical data showed that BRCA patients on long term treatment with BZDRs suffered increased mortality rate (p = 0.034). Studies on patient samples indicated that among 16 GABA receptors examined, GABRA3 (a pro-tumorigenic player) was significantly upregulated by BZDRs, which advanced BRCA disease. To support our clinical findings, we examined in vivo, the impact of BZDRs on BRCA advancement using MDA-MB231 cells to mediate metastasis in mice model. Our results show that BZDRs indeed promoted cancer advancement to the lungs and localized in the tibia. Using BRCA cell lines, we revealed the molecular-cellular effects of prolonged treatment with BZDRs in vitro. We showed significant metastasis indicated by increased cancer cell migration and invasion, which correlated well with our clinical observations. We discovered that BZDR-mediated GABRA3 stimulation was associated with downregulation of anti-tumorigenic extracellular matrix (ECM) molecules (S100B, COL6A6 and VIT) and upregulation of pro-tumorigenic FBN3 in BRCA cells. Notably, GABRA3-shRNA and GABRA3-CRISPR/Cas9 disrupted the abovementioned dynamics dramatically and suppressed BRCA cell invasion induced by BZDRs. Bioinformatics analyses highlighted molecular pathways showing interplay between GABRA3 and ECMs, which presumably exacerbated BZDR-induced BRCA progression via immune modulators.</p><p><strong>Conclusions: </strong>Long-term clinical use of BZDRs significantly increased the mortality rate of BRCA patients.

Neutrophils, the predominant white blood cells in the innate immune system, are increasingly becoming known as potential contributors to either tumor-promoting or tumor-suppressive activities within different tumor biology settings. This review highlights such dual roles of neutrophils in GC, where complex interactions occur within the tumor microenvironment. Specifically, we focus on the formation and function of neutrophil extracellular traps (NETs), which have emerged as critical players in GC progression. NETs influence key processes such as inflammation, angiogenesis, and metastasis. This review offers a comprehensive analysis of the polarization of neutrophils into two of its distinct subtypes, namely N1 and N2, which exert opposing influences on tumor biology. While N1 neutrophils exert anti-tumor properties, N2 neutrophils are generally regarded as pro-tumor. We uniquely discuss how these subtypes interact with cancer cells, affecting epithelial-mesenchymal transition and immune evasion mechanisms. These interactions change the tumor microenvironment and impact overall GC progression. In addition, we underscore the potential of neutrophils and their associated molecules as biomarkers and therapeutic targets. Specific neutrophil-derived markers and neutrophil-associated signaling pathways, along with their perspectives in personalized medicine that would pave the way for neutrophil-based anti-GC therapy, have been discussed in this review. Through the integration of these perspectives, we aim to guide future research involving neutrophils and their therapeutic implications, thus establishing strategies to precisely and effectively treat GC and improve prognosis.</p>","PeriodicalId":9688,"journal":{"name":"Cellular & Molecular Biology Letters","volume":"30 1","pages":"71"},"PeriodicalIF":9.2,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12168313/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in the early phase of acute kidney injury, macrophages shift to a pro-inflammatory role relying on glycolysis and pentose phosphate pathways. The tissue microenvironment regulates the suppression of glycolysis-related genes and the up-regulation of oxidative phosphorylation and tricarboxylic acid cycle genes in macrophages, resulting in a gradual shift to an anti-inflammatory phenotype, which is involved in tissue repair and remodelling. In the late stage of injury, if macrophages continue to be overactive, they will be involved in renal fibrosis.

Therefore, regulation of macrophages to intervene in the progression of infection-induced lung injury is a promising research direction. However, the existence of different macrophage subsets and their inherent heterogeneity has led to the failure of many studies to achieve effective results, thereby limiting their clinical applications.

It occurs during periods of glucose starvation, specifically when intracellular NADPH is rapidly depleted and the expression of Solute Carrier Family 7 Member 11 (SLC7A11) is highly upregulated. Cancer cells utilize SLC7A11 to import cystine from the extracellular environment, and subsequently employ NADPH to convert it into cysteine. In the event of NADPH deficiency or an impairment in its utilization, cystine accumulates within the cells. This accumulation results in abnormal disulfide bond formation within actin cytoskeleton proteins, which in turn causes the collapse of the actin network and ultimately triggers disulfidptosis. This process uncovers a metabolic vulnerability within tumors, offering novel perspectives on the mechanisms that underlie cell death. In this paper, we provide a comprehensive review of the mechanism of disulfidptosis and compare its similarities and differences with other common programmed cell death mechanisms, such as apoptosis, autophagy, ferroptosis, and cuproptosis.
