Amino-bisphosphonates (N-BPs) have a wide range of clinical applications to treat bone diseases. Their activity lowered farnesyl pyrophosphate (FPP) endogenous levels by inhibiting FPP synthase. In epithelial cells it has been demonstrated that FPP reduces both cell proliferation and migration activting glucocorticoid receptor. In this study two N-BPs (zoledronate and neridronate) used at low concentrations (100 nM to 10 μM) are able to stimulate human keratinocytes proliferation reducing glucocorticoid receptor activation.

Limited literature addresses the association between pollution, stress, and obesity, and knowledge synthesis on the associations between these three topics has yet to be made. Two reviewers independently conducted a systematic review of MEDLINE, Embase, and Web of Science Core Collection databases to identify studies dealing with the effects of semi-volatile organic compounds, pesticides, conservatives, and heavy metals on the psychosocial stress response and adiposity in humans, animals, and cells. The quality of papers and risk assessment were evaluated with ToxRTool, BEES-C instrument score, SYRCLE's risk of bias tool, and CAMARADES checklist.

Stressful and emotionally arousing experiences induce the release of noradrenergic and glucocorticoid hormones that synergistically strengthen memories but differentially regulate qualitative aspects of memory. This highlights the need for sophisticated behavioral tasks that allow for the assessment of memory quality. The dual-event inhibitory avoidance task for rats is such a behavioral task designed to evaluate both the strength and specificity of memory.

Technological innovation can drive scientific inquiry by allowing researchers to answer questions that were once out of reach. Eukaryotic mRNA synthesis was not so long ago thought of as a deterministic, sequential process in which transcriptional regulators and general transcription factors assemble in an orderly fashion into chromatin to, ultimately, activate RNA polymerase II. Advances in fluorescence microscopy techniques have revealed a much more complex scenario, wherein transcriptional regulators dynamically engage with chromatin in a more stochastic, probabilistic way.

Objective: This study seeks to elucidate the role and molecular mechanisms of IL-8 in nasal epithelial cell pyroptosis and its impact on glucocorticoid (GC) resistance.
Methods: We assessed the expression of pyroptosis-related biomarkers and IL-8 in tissues and human nasal epithelial cells (hNECs) from both control and nasal polyp patients using western blot. Their localization was determined through immunohistochemistry and immunofluorescence.

One key determinant of HIV-1 latency reversal is the activation of the viral long terminal repeat (LTR) by cellular transcription factors such as NF-κB and AP-1. Interestingly, the activity of these two transcription factors can be modulated by glucocorticoid receptors (GRs). Furthermore, the HIV-1 genome contains multiple binding sites for GRs.
