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.

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 addition, ICS II had a strong binding with Keap1 and Nrf2 inhibitor ML385 partially abolished the suppressive role of ICS II in MPP-triggered apoptosis, oxidative stress, and ferroptosis in SK-N-SH cells. To summarize, ICS II might inhibit apoptosis, oxidative stress, and ferroptosis in the MPP-stimulated PD cell model, which might be due to the activation of Keap1/Nrf2/GPX4 signaling.

Higher expression of MnSOD in patients with endometrial cancer and T2DM is associated with better overall survival if the patient is consuming metformin.

Nevertheless, KFD supplementation significantly (P < 0.05) abrogated all the damages induced by PE-MPs. The findings of our study demonstrated that KFD could significantly attenuate PE-MPs-instigated OS and testicular toxicity, due to its anti-oxidant, anti-inflammatory, androgenic and anti-apoptotic potential.

H460 KEAP1/STK11 mutant cell line derived xenograft model was used to demonstrate the anti-tumor activity of LP-184. LP-184 displayed strong nanomolar potency in 7 day ex vivo treatment in a panel of patient derived lung cancer models carrying ATM, BRCA1 or CHEK1 mutations with IC50s in the range of 30 - 200 nM, which turned out to be 12-350 times superior to that of Olaparib across the same models. LP-184 is highly effective in selected molecular subsets of lung cancer in proof-of-concept ex vivo and in vivo studies, supporting its clinical development in small cell and non-small cell lung cancers. IND-enabling repeat dose GLP toxicology studies of LP-184 show it to be well tolerated in rats and dogs. A first-in-human dose escalation Phase 1A trial with LP-184 is expected to enroll all advanced solid tumors including lung cancers.

These data demonstrated that CPW prevented HO-induced oxidative stress by regulating the Keap1/Nrf2 signaling pathway.

Such functions were further determined by multiple experiments in vivo (i.e., subcutaneous tumour formation in nude mice) and in vitro (e.g., cell cloning, infection, migration, wound healing, cell cycle, apoptosis, CAT enzymatic activity, and intracellular GSH levels). Of note, the results obtained from tumourigenesis experiments in xenograft model mice were verified based on the prominent changes in the PTEN signaling to the PI3K-AKT-mTOR pathways, in addition to substantially aberrant expression patterns of those typical genes involved in the EMT (epithelial-mesenchymal transition), cell cycle, and apoptosis.
