Although chemotherapy and targeted therapies have advanced significantly, relapse and chemoresistance continue to be the major clinical challenges, which emphasizes the need for novel treatments. Brusatol, a natural quassinoid compound, has been reported to exert anti-tumor effects in various solid tumors; however, its anti-leukemic activity and potential mechanism in AML remain poorly characterized. THP-1 and KG-1a cells were treated with brusatol alone or combined with venetoclax. Proliferation was evaluated by CCK-8, cell counting and morphological observation. Apoptosis was detected by flow cytometry, Western blot, morphological changes and TUNEL staining. RNA-seq with GO, KEGG, and GSEA was used to identify key pathways. Cell cycle was analyzed by flow cytometry. DNA synthesis was detected by EdU assay. mRNA expression was measured by qPCR. Protein levels were determined by Western blot. Brusatol significantly suppressed the proliferation of AML cells. Moreover, brusatol notably increased the apoptotic rate, upregulated the expression of cleaved‑PARP and Bax, downregulated MCL1, and induced typical apoptotic morphological changes. Transcriptomic analysis demonstrated that brusatol primarily modulated pathways related to the cell cycle and steroid biosynthesis. Brusatol downregulated the expression of MCM2, PCNA, and CDK2, thereby inducing cell cycle arrest and inhibiting DNA replication. Brusatol also significantly reduced the expression of key genes involved in steroid biosynthesis, including DHCR7, SQLE, EBP, and FDFT1. Furthermore, co-treatment with brusatol and venetoclax strengthens cell cycle arrest, proliferation inhibition and apoptosis induction in AML cells compared with single drug treatment. Brusatol inhibits AML cell proliferation, induces apoptosis, triggers cell‑cycle dysregulation, and downregulates sterol‑biosynthesis‑related gene expression. Brusatol also enhances the anti-leukemic activity of venetoclax.

RNA-binding proteins (RBPs) are important post-transcriptional regulators of tumorigenesis, but their roles in NPC remain poorly understood. This study investigated whether RNA-binding motif protein 4 (RBM4) stabilizes homeobox B13 (HOXB13) mRNA and thereby activates oncogenic signaling to promote NPC progression. Bioinformatics analysis identified differentially expressed genes in NPC. ENCORI was used to predict potential RNA-binding proteins (RBPs) targeting the candidate gene, and the predicted interaction was validated by RNA immunoprecipitation. Functional effects of HOXB13 and RBM4 in NPC cells were examined using colony formation and Transwell assays, along with modulating RBM4, HOXB13, nuclear factor kappa B (NF-κB) p65, and β-catenin expression. In vivo, effects of the RBM4/HOXB13 axis on NPC tumor growth and metastasis were evaluated using murine xenograft and lung metastasis models. HOXB13 was among the most strongly upregulated genes in NPC, and RBM4 was predicted to be a candidate RBP targeting HOXB13 mRNA. RBM4 was also upregulated in NPC models and increased HOXB13 mRNA stability. RBM4 silencing suppressed NPC cell proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT), while increasing apoptosis and reducing HOXB13 expression and NF-κB and Wnt/β-catenin signaling. Overexpression of HOXB13, NF-κB p65, or β-catenin partially reversed these effects. In vivo, RBM4 silencing inhibited xenograft growth and experimental lung metastasis, and these effects were partially reversed by HOXB13 overexpression. RBM4 acts as a pro-tumorigenic RBP in NPC by stabilizing HOXB13 mRNA and activating the NF-κB and Wnt/β-catenin pathways.

These modifications result in the formation of advanced glycation end products (AGEs), which promote protein aggregation, impair cellular clearance, and induce oxidative and inflammatory damage via the AGE-RAGE axis. This cascade, characterised by increased reactive oxygen and nitrogen species, mitochondrial dysfunction, and metabolic imbalance, accelerates neuronal degeneration and disease progression.This study investigates trans-ferulic acid (TF) as a multifunctional therapeutic candidate targeting this interconnected network. TF effectively inhibited glycation in both ribose and Me-induced α-Syn systems, demonstrating strong antiglycation potential. Additionally, TF exhibited significant scavenging activity against hydrogen peroxide and nitric oxide, underscoring its capacity to reduce oxidative and nitrosative stress. TF also inhibited α-glucosidase, indicating a further mechanism for controlling glucose availability and limiting the formation of reactive intermediates. Collectively, these findings identify TF as a promising multi-target agent capable of disrupting the glycation-oxidative stress cycle at multiple levels.
