    Article Title: Peptide WCPFSRSF ameliorates excitotoxicity and elevates synaptic plasticity in glutamate-damaged SH-SY5Y cells by modulating the PI3K/mTOR/EIF4E and BDNF/CREB/TrkB pathways
    Article Snippet: The purpose of this study was to illustrate the beneficial effects and underlying mechanisms of peptide Trp-CysPro-Phe-Ser-Arg-Ser-Phe (WCPFSRSF) against excitotoxicity by transcriptome analysis combined with western blot in glutamate-treated neuronal cells.. Our results demonstrated that WCPFSRSF restored the cell membrane damage induced by glutamate and promoted cell survival in SH-SY5Y cells.. The RNA-sequencing analysis illustrated 376 genes (98 upregulated and 278 downregulated) were differentially expressed between the glutamateand WCPFSRSF-treated cells.

    Article Title: Yin Yang 1 suppresses tumor invasion and metastasis in nasopharyngeal carcinoma by negatively regulating eIF4E transcriptional activity and expression

    Article Title: WDR4 drives tumour-associated macrophage reprogramming and tumour progression via selective translation and membrane cholesterol efflux.
    Article Snippet: Tumour-associated macrophages (TAMs) play a pivotal role in shaping the immune microenvironment of hepatocellular carcinoma (HCC), influencing tumour progression and immunotherapy response.. WDR4, a tRNA-binding cofactor of the N-methylguanosine (mG) methyltransferase complex, remains poorly understood in its independent functions.. Here we show that WDR4 is significantly upregulated in HCC-associated TAMs and correlates with poor prognosis.
