TFRC upregulation promotes ferroptosis in CVB3 infection via …
2022年7月11日 · Intriguingly, we found that CVB3-induced cell death could be effectively attenuated by Fer-1 and DFO, suggesting that ferroptosis played a important role in CVB3-induced cell death. This study...
Transferrin Receptor Promotes Endometrial Cancer Proliferation by ...
2025年3月1日 · TFRC facilitated EC proliferation by activating the mTOR signaling pathway in an iron-dependent manner. Collectively, TFRC may serve as a critical prognostic indicator for risk assessment in EC patients and propose TFRC as a promising therapeutic target to …
Science Advances丨NRF2 通过 HERC2 和 VAMP8 控制铁稳态和铁 …
转铁蛋白受体 1(TFRC/TFR1)是控制铁摄取的主要受体,在所有细胞系中,IKE 处理在蛋白而非 mRNA 水平上适度诱导了该受体,而与 NFE2L2/NRF2 WT 细胞相比,在所有 NFE2L2/NRF2 KO 细胞中,TFRC/TFR1 mRNA 水平略有降低,但蛋白水平没有降低(图 2,C 和 D)。 相反,NFE2L2/NRF2 KO 改变了许多参与铁蛋白合成和降解的蛋白质 [HERC2、F-盒和富含亮氨酸重复蛋白 5 (FBXL5)、铁调控蛋白 2 (IRP2) 和 NCOA4]的表达(图 2,C 和 D)。 (图 2,C 和 …
TRIB2 desensitizes ferroptosis via βTrCP-mediated TFRC
2021年7月27日 · In conclusion, we elucidated a novel role of TRIB2 to desensitize ferroptosis via E3 βTrCP, by which facilitates TFRC ubiquitiation and finally decreases labile iron in liver cancer cells. TRIB2...
Iron promotes ovarian cancer malignancy and advances platinum ...
2024年5月13日 · Cells absorb iron by binding to transferrin and internalizing it via the transferrin receptor (TFRC). Most iron forms iron-sulfur bonds and contributes to hemoglobin synthesis, with excess iron...
Iron Metabolism in Ferroptosis - Frontiers
2020年10月6日 · Transferrin receptor (TFRC/TFR1) is a dimeric glycoprotein receptor for iron-loaded TF at the surface of plasma. The extracellular domains of TFRC have high affinity to bind diferric TF, as compared to monoferric TF or apo-TF. Following binding to TFRC, the TF-TFRC complex is internalized via receptor-mediated endocytosis.
Nature cell biology(IF=21.3)铁元素推动新陈代谢的机制 - 知乎
使用去铁胺 (DFO)处理HEK293T细胞,mTORC1活性从12小时开始完全抑制,一直持续到24小时 (图1B)。 DFO处理24小时后观察到铁水平显著降低,而磷和钾水平没有下降,这表明即使在ID持续时间延长的情况下,细胞也能够维持膜电位 (图1C)。 与DFO螯合18小时后重新加入等摩尔浓度的Fe2+、Cu2+或Zn2+, 结果表明只有重新添加铁才足以挽救mTORC1活性 (图1D)。 DFO处理18小时减少了嘌呤霉素和35S蛋氨酸在延长肽链中的掺入 (图1E,F),证实铁缺乏细胞的蛋白质合 …
去铁胺诱导的TfR1和DMT1高表达通过激活IL-6 / PI3K / AKT途径增 …
结果:在这项研究中,我们发现DFO处理显着提高了侵略性TNBC中铁摄取蛋白DMT1和TfR1的水平。 此外,在DFO诱导的铁缺乏条件下,细胞膜上表达的TfR1和DMT1都参与了TNBCs的高铁吸收。 对于可能的调节机制,我们发现DFO处理可以促进侵袭性MDA-MB-231细胞中IL-6的高表达水平。 激活的IL-6 / PI3K / AKT途径上调了铁摄取相关蛋白TfR1和DMT1的表达,从而导致铁摄取增加。 结论:我们证明了DFO可以上调TfR1和DMT1的表达,并通过激活侵袭性TNBCs中的IL …
METTL3 regulates TFRC ubiquitination and ferroptosis through ...
2024年2月2日 · Overexpressing METTL3 inhibits the iron carrier protein TFRC by upregulating the E3 ubiquitin ligase NEDD4L, thereby alleviating oxidative damage and ferroptosis to protect the brain from ischemic injury. Mechanistic studies show METTL3 can methylate and stabilize NEDD4L mRNA, enhancing NEDD4L expression.
Dihydroartemisinin Sensitizes Lung Cancer Cells to Cisplatin …
2024年10月12日 · Our findings suggest that combining dihydroartemisinin (DHA) with cisplatin (DDP) presents a promising strategy to overcome chemoresistance in lung cancer patients. Importantly, administering DHA during chemotherapy intervals could further optimize treatment outcomes, enhancing the overall efficacy of lung cancer chemotherapy.
