Good Quality 66.7% 5-year Overall Survival in Terminal Lung Cancer Patients Treated With Mifepristone. (PubMed, Anticancer Res)
The likelihood of this type of response occurring by chance is extremely low. It is hoped that this report will encourage oncologists, scientists, and clinicians to further investigate the use of SPRMs in a larger cohort of patients with stage IV lung cancer, and potentially in those with less advanced disease.

Expression of Glucocorticoid Receptor and FOXO1/phospho-FOXO1 in Bladder Cancer as Independent Prognosticators. (PubMed, Cancer Genomics Proteomics)
The expression levels of GR and FOXO1 or p-FOXO1 were strongly correlated in bladder cancer. Specific GR/FOXO1 and GR/p-FOXO1 expression profiles served as independent predictors of disease recurrence or progression.

Stress induces corticosterone-mediated CD8+ T cell exhaustion to promote non-small cell lung cancer. (PubMed, Cancer Immunol Immunother)
In brief, our study demonstrates that stress-corticosterone axis induces exhaustion of tumor-infiltrating CD8+ T cells, contributing to accelerated progression of non-small cell lung cancer.

Endometrial Changes Associated with Mifepristone: A Review. (PubMed, Int J Gen Med)
Monitoring of estradiol(E2) levels before the management is recommended. Risk assessment and preventive strategies, such as intermittent treatment, transvaginal ultrasound and levonorgestrel intrauterine system (LNG-IUS), should be considered.

Chronic stress-secreted glucocorticoid induces NAFLD-like changes in male rats: Oxidative stress/NLRP3 inflammasome signalling. (PubMed, J Mol Endocrinol)
Fifty 8-week-old healthy male Wistar rats were divided into five groups (n=10 each) as follows: control, CS, CS+Mifepristone (CS+Mif), CS+Metyrapone (CS+Met), and Corticosterone (Cort). In this study, we investigated the molecular mechanism underlying the CS-related NAFLD. GC mediates the development of oxidative stress and inflammation in the liver, and inhibition of the GC signalling may be a new therapeutic strategy.

Deoxypodophyllotoxin induces apoptosis in non-small cell lung cancer cells by targeting the glucocorticoid receptor. (PubMed, Arch Biochem Biophys)
These findings suggest that DPT exerts its anticancer effects by disrupting the GR/TSC22D3 axis in NSCLC cells, highlighting its potential as a therapeutic agent for GR-associated cancers.

Protective effect of glucocorticoid receptor against lung inflammation induced by nicotine-derived nitrosamine ketone is mediated by suppression of the ROS-mediated cyclooxygenase-2/prostaglandin E2 pathway in human distal lung epithelial A549 cells. (PubMed, Toxicol Lett)
The NNK-induced increase in COX-2 expression and PGE2 production was inhibited by glucocorticoids, and this effect was antagonized by the GR antagonist, RU38486...The ROS scavenger N-acetylcysteine inhibited the NNK-induced increase in COX-2 mRNA levels and promoter activity. Furthermore, dexamethasone significantly inhibited NNK-induced cell invasion. Conclusively, the data collectively indicate that NNK-induced ROS activates the COX-2/PGE2 pathway and cell invasion in lung cancer cells. These findings elucidate the pathophysiological connection between NNK, GR, inflammatory responses, and cell metastasis.
