KEAP1 expression

The ABC subtype was also associated with lower white blood cell counts and more frequent chemotherapy courses than the GCB subtype. These findings suggest that nuclear Nrf2 could be a biomarker for DLBCL clinical diagnosis.

To sum up, the present research indicated that DBH can ameliorate D-gal-induced oxidative stress and apoptosis by regulating the Nrf2/HO-1 signalling pathway and the Bcl-2/Bax/caspase-3 apoptosis pathway, which can be used for further development as a nutraceutical product to improve premature ovarian failure.

Furthermore, the growth rate of CRC tumors was associated with alterations in the levels of oxidative stress enzymes and Keap1 expression in animals with a high metabolic rate. Our results indicate that a faster growth and development of CRC line DLD-1 is associated with enzymatic redox imbalance in animals with a high BMR.

Inhibition of miR-141-3p promoted Keap1 expression, inhibited Nrf2 and its downstream SLC7A11-GSH-GPX4 signaling pathway, as well as promoted ferroptosis in cancer cells, and inhibited paclitaxel and RSL3 resistance. In vivo, miR-141-3p mimics promoted paclitaxel resistance, whereas miR-141-3p inhibitors inhibited paclitaxel resistance in breast cancer cells. This work revealed that modulation of the Keap1-Nrf2 signaling pathway by miR-141-3p promoted paclitaxel resistance via regulating ferroptosis in breast cancer cells.

These result suggest that maternal TFA exposure during gestation can result in oxidative stress and inflammation to brain of offspring in a way. SDG can protect brain of mice of offspring from TFA-induced oxidative injury by up-regulating the expression of mRNA and protein of Nrf2, down-regulating the expression of Keap1, accelerating expression of protein of NQO1 and HO-1 which are antioxidant protein lying downstream of pathway of Nrf2/Keap1.

Besides, PQ exposure prompted various histopathological damages in renal tissues. Nonetheless, SCN substantially restored aforementioned alterations in renal tissues owing to its anti-oxidative, anti-inflammatory and anti-apoptotic potential.

These findings demonstrate the inhibitory effects and associated mechanisms of AAVC-I on the HSC-3 OSCC cell line. This insight could be valuable for investigating AAVC-I as a potential therapeutic option for patients with OSCC.

Taken together, GF2 ameliorated MI by preventing cardiocyte apoptosis, oxidative stress, and mitochondrial dysfunction via modulating the Nrf2/HO-1 and PI3K/Akt signaling pathways, showing potential as a treatment strategy for treating MI.

ERCN treatment remarkably ameliorated the hepatic tissues owing to its antioxidant, anti-inflammatory, and anti-apoptotic potentials. These findings underscore the therapeutic potential of ERCN to counteract the adverse effects of environmental pollutants on hepatic tissues.

Mitochondrial dysfunction manifested with diminished activities of Krebs cycle and respiratory chain enzymes, and reduced mitochondrial membrane potential. Co-treatment with hyperin significantly attenuated these detrimental effects through its anti-apoptotic, antioxidant, and anti-inflammatory properties. Hyperin co-treatment significantly attenuated CdCl2-induced renal damage in mice, suggesting its potential as a protective agent against cadmium-induced kidney toxicity.

Background: KRAS G12C inhibitors (G12Ci) are revolutionizing the therapeutic landscape of advanced NSCLC, but mechanisms of limited clinical efficacy observed in some patients (pts) merit continued exploration. Co-mutations in KEAP1 and STK11 and NRF2 signaling define a subgroup of KG12C NSCLC pts with markedly distinct outcomes upon treatment with ada. The mTORi and ada combination shows high efficacy for targeting KG12C NSCLC harboring KEAP1 and STK11 co-mutations. The clinical safety and efficacy of mTORi nab-sirolimus and ada will be determined in the ongoing KRYSTAL-19 trial (NCT05840510).

In summary, our findings shed light on the mechanism of PD-L1 degradation and how NSCLC immune escape through KEAP1-PD-L1 signaling. Our results also suggest that KEAP1 agonist might be a potential clinical drug to boost anti-tumor immunity and improve immunotherapies in NSCLC.
