2021年8月31日 · Here, we find that nuclear factor-kB (NF-κB) p65 is a new substrate of FBXW2. FBXW2 directly binds to p65, leading to its ubiquitination and degradation. Interestingly, p300 acetylation of...

Proposition 65 warnings advise of exposures to chemicals that may contribute to an individual's overall lifetime risk of cancer or risk of birth defects or other reproductive harm. If a warning is placed on a product label or posted or distributed at a workplace, a business, or in rental housing, the business issuing the warning is aware or ...

2024年11月15日 · In the present study, we demonstrated its enhanced active nuclear localization in TAMs and validated selected immune target genes as directly regulated by dimer binding on DNA sequences. We demonstrated by ChIP-qPCR that p65/p52 enrichment on HSPG2 and CSF-1 regulatory regions is strictly dependent on macrophage polarization and tumor environment.

Hence, the NF-κB p65 signaling pathway has been a pivotal point for intense drug discovery and development. This review begins with an overview of p65-mediated signaling followed by discussion of strategies that directly target NF-κB p65 in the context of chronic inflammation. Keywords: NF-κB, inflammation, therapy.

NF-κB p65 是NF-κB家族成员之一，NF-κB是一种多效性转录因子，几乎存在于所有细胞类型中，并参与许多生物学过程，例如炎症、免疫、分化、细胞生长、肿瘤发生和凋亡。 NF-κB受翻译后修饰和亚细胞区室化的各种机制以及与其他辅因子或共抑制因子的相互作用的控制。 p65-RelA是哺乳动物NF-κB家族的成员，该家族由5个亚基组成：p50-NF-κB1，p52-NF-κB2，c-Rel，p65-RelA和RelB。

3 天之前 · Serum proteomics reveals that irradiated-tumor-secreted PAI-1 triggers distant tumor pericyte cell-fate transition into SFRP2 high CAFs via the LRP1/p65 axis. Pharmacologically blocking SFRP2 or PAI-1 enhances the abscopal effect in …

2025年2月5日 · The tumor microenvironment is a dynamic ecosystem, that evolves with the developing tumor to support its growth and metastasis. A key aspect of TME evolution is the recruitment of stromal fibroblasts, carried out via the release of various tumor signals including tumor necrosis factor (TNF α).

2024年10月18日 · Our findings demonstrate that the NF-κB p65 subunit plays a crucial role in promoting tumor growth and modulating the immune microenvironment in CRC, particularly in the context of T1D. Knocking down p65 not only reduces tumor progression but also enhances the anti-tumor immune response by decreasing immune evasion mechanisms.

The key to the regulation of NF-κB function is to inhibit the promotional effect of Rel A ( p65) on liver tumor. Therefore, inhibiting the activity of NF-κB p65 may suppress the differentiation and growth of tumor cells, providing a new idea for clinical treatment of HCC.

2024年5月17日 · Analysis of clinical samples reveals that high expression of DEF is correlated with diminished survival in pancreatic cancer patients. Crucially, the depletion of DEF significantly impedes tumor growth. The study further discovers that DEF binds to p65, shielding it from degradation mediated by the ubiquitin-proteasome pathway in cancer cells.
