ABSTRACT Formin1 (FMN1), a member of the non-diaphanous formin family, is essential for development and neuronal function. Unlike diaphanous-related formins, FMN1 not subject to canonical autoinhibition through DID DAD domains, nor it activated by Rho GTPase binding. Recent studies suggest that formins also play roles in nucleus, influencing DNA damage response transcriptional regulation. However, mechanisms regulating nuclear particularly ones like remain poorly understood. Our previous research identified interaction between FNBP4, prompting further investigation into its functional role actin dynamics. Results reveal FNBP4 inhibits FMN1-mediated assembly vitro.

Abstract According to statistics, the incidence of liver cancer is increasing yearly, and effective treatment imminent. For early cancer, resection surgery currently most treatment. However, does not treat disease in advanced patients, so finding a method with better prognosis necessary. In recent years, ferroptosis cuproptosis have been gradually defined, related studies proved that they show excellent results therapy cancer. Cuproptosis new form cell death, use combined inhibit production hepatocellular carcinoma cells has good development prospects worthy in-depth discussion by researchers. this review, we summarize research progress on treating analyze value immune propose potential pathways oncotherapy combination ferroptosis, which can provide background knowledge for subsequent research.

Gastrointestinal (GI) cancer is one of the most severe types cancer, with a significant impact on human health worldwide. Due to urgent demand for more effective therapeutic strategies against GI cancers, novel research metal ions treating cancers has attracted increasing attention. Currently, accumulating relationship between and therapy, several have been discovered induce cell death. In particular, three modes death, including ferroptosis, cuproptosis, calcicoptosis, become focal points in field cancer. Meanwhile, other also found trigger death through various mechanisms. Accordingly, this review focuses mechanisms ion-induced hoping provide theoretical support further therapies.

Methylglyoxal (MGO), a highly reactive precursor of advanced glycation end products, is endogenously produced and prevalent in various food products. This study aimed to characterize protein modifications SH-SY5Y human neuroblastoma cells induced by MGO identify potential biomarkers for its exposure toxicity. A shot-gun proteomic analysis was applied treated with without exogenous MGO. Seventy-seven proteins were identified as susceptible modification, among which eight, including vimentin histone H2B type 2-F, showing concentration-dependent externally added MGO, defined exposure. Remarkably, up 10 modification sites on vimentin. Myosin light polypeptide 6 emerged biomarker toxicity, exclusively observed under cytotoxic levels. Additionally, like serine/threonine-protein kinase SIK2 calcyphosin, exhibiting comparable or even higher levels control compared MGO-treated cells, endogenous Bioinformatics revealed that motor proteins, cytoskeleton components, glycolysis overrepresented those modification.

ERβ has been assigned a tumor suppressor role in many cancer types. However, as conflicting findings emerge, ERβ’s tissue-specific expression and functional have remained elusive. There remains notable gap compact comprehensive analyses of ESR2 mRNA levels across diverse types coupled with an exploration its potential gene network. In this study, we aim to address these gaps by presenting analysis transcriptomic data. We distinguished significant changes compared corresponding healthy tissue concluded that influences patient survival. Gene Set Enrichment Analysis (GSEA) molecular pathways affected ESR2, including oxidative phosphorylation epithelial–mesenchymal transition. Finally, investigated genes displaying similar patterns tissues, identifying co-expressed may exert synergistic effect on clinical outcomes, results, the ACIN1, SYNE2, TNFRSF13C, MDM4.
