Current data suggest that mitochondrial Stat3 (mitoStat3) is necessary for maximal mitochondrial activity and for Ras-mediated transformation independent of Stat3 nuclear activity. We have previously shown that Stat3 plays a pivotal role in epithelial carcinogenesis.
NRF1 - Wikipedia
Nuclear respiratory factor 1, also known as Nrf1, Nrf-1, NRF1 and NRF-1, encodes a protein that homodimerizes and functions as a transcription factor which activates the expression of some key metabolic genes regulating cellular growth and nuclear genes required for respiration, heme biosynthesis, and mitochondrial DNA transcription and ...

Neuroprotective Effects of STAT3 Inhibitor on Hydrogen
2024年12月9日 · We observed that STAT3 inhibitors promote CREB phosphorylation, leading to the upregulation of immediate early genes such as c-Fos, c-Jun, Arc, Egr-1, NR4A1, and Homer1a, as well as BDNF. These genes are crucial for synaptic plasticity and long-term memory formation, suggesting that STAT3 inhibition may ameliorate cognitive impairments in ...
Role of STAT3 and NRF2 in Tumors: Potential Targets for …
Specifically, genetic ablation of Stat3 in murine as well as STAT3 in human cells leads to an increase of NF-κB-induced expression of CXCL1/IL-8, which contributes to infiltration of myeloid cells as well as vascularization; while inhibiting CXCL1’s cognate receptor, CXCR2 can normalize tumor vascularization and microenvironment and reduce ...
