This study applies Mendelian randomization (MR) to investigate causal relationships between BC and three major types of NP: diabetic peripheral neuropathy(PDPN), postherpetic neuralgia(PHN), and trigeminal neuralgia(TN). We also explore the potential mediating role of immune cells in these associations. We employed a two-sample, two-step Mendelian randomization study using the inverse variance weighted method to investigate the causal effect of BC on three major types of NP, as well as the mediating role of immune cells in the association between BC and NP. Additionally, we utilized a two-step Mendelian randomization design to explore the mediating effect of immune cells. We identified 13 distinct blood cell phenotypes under various perturbation conditions that have a significant causal relationship with NP. Additionally, we discovered 127 immune cells that exhibit a notable causal connection with NP. Through Mendelian Randomization (MR) and two-step Mendelian Randomization analyses, we found the following results: Three blood cell phenotypes were associated with PDPN, three with PHN, and seven with TN, with platelet, red blood cell, monocyte, and neutrophil responses showing significant correlations with NP risks. Immune cell analyses revealed 36 phenotypes increasing and 31 decreasing PDPN risk, 16 increasing and 21 decreasing PHN risk, and 18 increasing and 13 decreasing TN risk, with HLA DR on DCs, PB/PC AC, and CD39+ CD4+ %T cell showing the strongest associations, respectively. Mediation analysis identified immune cells, such as CD39+ resting Treg and HLA DR+ CD4+ %lymphocyte, mediating PBC effects on NP risks. Sensitivity analyses confirmed no significant heterogeneity or pleiotropy, and reverse MR analyses found no reverse causal relationships. This study provides new evidence for the causal relationship between blood cell phenotypes and neuropathic pain and proposes immune factors with potential mediating effects.

They have a vigorous amount of potential as agents for nanomedicine applications because of their rare properties, which compose internal cavities, strong reactivity, globular form, solubility in water, and nanoscale size.

This study investigates the combinatory effects of alpha-mangostin (α-MG) and nab-paclitaxel on MCF-7 and MDA-MB-231 cell lines, utilizing the xCELLigence RTCA system for continuous real-time cellular analysis, BrdU incorporation assays for proliferation assessment, and the quantification of mitotic activity and caspase-3/7 levels to elucidate apoptotic mechanisms. Our findings demonstrate that both α-MG and nab-paclitaxel independently induce significant inhibition of cellular proliferation and modulate cell cycle dynamics over a 24 to 72-hour period. Notably, when combined, these agents exhibit a pronounced enhancement of cell cycle inhibition and apoptosis, surpassing the effects observed with monotherapy. This potentiation effect suggests that α-MG augments the therapeutic efficacy of nab-paclitaxel, potentially allowing for reduced dosages in clinical applications. The study underscores the potential of α-MG as an adjuvant in breast cancer treatment, offering a promising strategy to optimize therapeutic regimens, minimize adverse effects, and improve patient outcomes in clinical oncology.</p>","PeriodicalId":9802,"journal":{"name":"Cellular and molecular biology","volume":"71 1","pages":"52-59"},"PeriodicalIF":1.5,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143254781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
