RAB7 deficiency impairs pulmonary artery endothelial function …
2024年2月2日 · In RAB7-deficient ECs, we detected a loss of ΔΨ m, with a shift toward dysfunctional mitochondria and evidence of reduced mitochondrial respiration with enhanced glycolysis. The RAB7 GTPase activator ML-098 reduced severe PH in chronic hypoxia/SU5416 (Hx/Su) rats, thus identifying RAB7 as a potential therapeutic target in PAH. Go to:

为了研究 Rab7 在体内调节 EV 释放中的作用,作者将 Rab7f/f 小鼠与他莫昔芬诱导型 Myh6-MerCreMer (MCM) 转基因小鼠杂交,以允许成年心脏中肌细胞特异性删除 Rab7。
Rab7 reduces α-synuclein toxicity in rats and primary neurons
2022年1月1日 · In this work, we tested whether stimulating the autolysosomal degradation of αSyn aggregates through the Ras-related in brain 7 (Rab7) pathway can reverse αSyn-induced cellular impairment and prevent neurodegeneration in vivo.
Mitochondria–lysosome contacts regulate mitochondrial fission via RAB7 …
2018年1月24日 · Contact formation was promoted by active GTP-bound lysosomal RAB7, and contact untethering was mediated by recruitment of the RAB7 GTPase-activating protein TBC1D15 to mitochondria by FIS1 to...
Rab7-a novel redox target that modulates inflammatory pain
Knockout mice lacking Rab7 in sensory neurons showed normal responses to noxious thermal and mechanical stimuli; however, their pain behavior during inflammatory pain and in response to ROS donors was reduced. The data suggest that redox-dependent changes in Rab7 activity modulate inflammatory pain sensitivity.
TBC1D15/RAB7-regulated mitochondria-lysosome interaction confers ...
2020年9月14日 · The TBC1D15/Fis1/RAB7 signaling cascade is deemed a critical process regulating the mitochondria-lysosome contacts. Active GTP-bound RAB7, a small GTPase from the Rab family, facilitates mitochondria-lysosome contacts and regulates lysosomal transport, fusion and maturation.

自噬研究指南|大自噬的关键——自噬溶酶体的形成(二) - 知乎
2023年10月7日 · Armus通过调节RAB7的核苷酸循环,以调节自噬溶酶体的形成,限制Armus功能导致RAB7活性异常升高,进而抑制自噬小体与溶酶体的融合 [9]。
专家点评Cell Research丨康铁邦团队发现新的外泌体通路 - 知乎
在EGF刺激条件下,通过免疫荧光和免疫印迹追踪EGFR的定位和降解,发现外源表达的RAB31可以将EGFR阻滞在CD63阳性MVEs而不进入溶酶体,即RAB31通过抑制MVEs和溶酶体融合来阻止EGFR的溶酶体降解。 因为MVEs和溶酶体融合由激活型RAB7介导,研究团队推测高表达的RAB31会抑制RAB7的活性。 通过检测细胞中激活型RAB7的水平和定位,研究团队证实外源表达的RAB31会显著降低细胞中激活型RAB7的水平,而且RAB31定位的晚期内体和MVEs表面没 …
Targeting Rab7‐Rilp Mediated Microlipophagy Alleviates Lipid …
2024年6月5日 · Promoting Rilp recruitment by Rab7 activator ML-098 rescued DbCM cardiac dysfunction. Our findings advance the understanding of microlipophagy and reveal a molecular target to mitigate lipid toxicity in DbCM by targeting the Rab7-Rilp axis.
