چکیده

Nur77 is a nuclear orphan receptor that has been implicated in both cell survival and apoptosis. With the exception of T-cells, translocation of Nur77 to the cytoplasm promotes cell death, while its retention in the nucleus promotes survival and proliferation. Nur77 appears to be a true orphan receptor, indicating that its activity must be controlled by ligand-independent mechanisms. Here, we discuss the role of phosphorylation in the regulation of Nur77.

MicroRNAs: Critical Regulators of mRNA Traffic and Translational Control with Promising Biotech and Therapeutic Applications

Context:MicroRNAs (miRNAs) are a class of short, endogenously-initiated, non-coding RNAs that post-transcriptionally control gene expression via translational repression or mRNA turnover. MiRNAs have attracted much attention in recent years as they play critical roles in gene expression and are promising tools with many biotech and therapeutic applications. The molecular mechanisms und...

Post-translational changes of histones, methylation level, and ERβ protein level in the cumulus cell genome of infertile women with endometriosis

Background: Endometriosis (which affects up to 50% of infertile women) is one of the major causes impacting female infertility. Endometriosis, defined as the presence of endometrial glands and stroma outside the uterine tissue, causes a wide range of functional disorders in the process of follicular development and changes in the follicular milieu, resulting in the formation of an incompetent o...

Regulation of the Nur77 orphan steroid receptor in activation-induced apoptosis.

T-cell receptor (TCR)-mediated apoptosis in immature thymocytes and T-cell hybridomas is calcium dependent and can be inhibited by cyclosporin A (CsA). Induction of the orphan steroid receptor Nur77 (NGFI-B) is required for activation-induced apoptosis. Here, we examined the regulation of Nur77 expression, in response to apoptotic TCR signals, which consists of kinase C and calcium pathways. We...

Nur77 deletion impairs muscle growth during developmental myogenesis and muscle regeneration in mice

Muscle atrophy is a prevalent condition in illness and aging. Identifying novel pathways that control muscle mass may lead to therapeutic advancement. We previously identified Nur77 as a transcriptional regulator of glycolysis in skeletal muscle. More recently, we showed that Nur77 expression also controls myofiber size in mice. It was unknown, however, whether Nur77's regulation of muscle size...

Bile acids regulate nuclear receptor (Nur77) expression and intracellular location to control proliferation and apoptosis.

UNLABELLED Bile acids (BA) are endogenous agents capable of causing cancer throughout the gastrointestinal (GI) tract. To uncover the mechanism by which BAs exert carcinogenic effects, both human liver and colon cancer cells as well as mouse primary hepatocytes were treated with BAs and assayed for viability, genotoxic stress, and transcriptional response. BAs induced both Nur77 (NR4A1) and pro...
