Summary: Q-BOLT is a small-molecule enzyme pair for optical voltage sensing that utilizes quenching of bioluminescence to visualize changes in membrane potential in live cells. It combines three distinct readouts - QRET, BRET, and the ratio between bioluminescence emission and BRET - to accurately report membrane potential oscillations in HEK 293T cells and hiPSCs, without the need for excitation light.

Summary: RNA-based nanostructures and molecular devices have been widely used for biosensors and genetic regulators. However, the high reliance on fluorescence as the readout can cause issues such as high background and phototoxicity. In this study, we developed the first genetically encoded RNA-based bioluminescence resonance energy transfer (BRET) sensors for real-time target detection in living cells. This novel system has potential applications in bioanalysis and nanomedicine for engineering biosensors, characterizing cellular RNA-protein interactions, and high-throughput screening or in vivo imaging.

Summary: This study evaluated the comprehensive activity of representative estrogen receptor (ER) ligands using BRET-based assays and provided information about receptor specificity and cellular estrogen signaling pathways. The results showed that various chemicals mediated ER alpha and ER8 dimerization, with some acting as estrogen agonists and others as antagonists. The study also supported the potential use of BRET assays as high-throughput screening methods for assessing the endocrine-disrupting activity of environmental agents.

Summary: In this study, BRET biosensors were developed to study the conformational changes of TRPC channels following receptor activation. The biosensors were tested in both cell lines and physiological conditions and showed successful detection of conformational changes. The results suggest that G alpha(q)-coupled receptor activation induces conformational changes in the TRPC7 BRET biosensor.

Summary: Lysophosphatidylinositol (LPI) and sphingosine-1-phosphate (S1P) are bioactive lipids that play important roles in cellular events such as proliferation, migration, and cancer progression. They act as ligands for G-protein coupled GPR55 and S1P receptors, respectively, and activate specific signaling pathways. Interestingly, the study found that co-activation of GPR55 and S1P receptors inhibits their stimulatory effects on colon cancer progression.

Summary: A novel cell-based assay was developed to evaluate the androgenic endocrine-disrupting properties of chemical substances, using a method to detect ligand-mediated androgen receptor (AR) dimerization in stably transfected human cell lines with a Bioluminescence Resonance Energy Transfer (BRET) system. The BRET-based AR dimerization assay demonstrated high accuracy, sensitivity, and specificity for detecting androgenic endocrine-disrupting chemicals (EDCs) and is suitable for practical use. This assay provides accurate information about androgenic endocrine-disrupting properties at the cellular level and complements conventional binding and transactivation assays.

Summary: Prostaglandins are bioactive lipids involved in various physiological and pathophysiological processes. This study investigated the signaling profiles of different isoforms of the human EP3 receptor, which is activated by the bioactive lipid PGE2. The research revealed potential differences in signaling mechanisms between isoforms and identified a specific antagonist with biased agonist effects on the Gαz pathway.

Summary: G protein-coupled receptors (GPCRs) are important transmembrane proteins involved in many physiological processes, and their targeted drug development has been widely promoted. However, research findings generated in immortal cell lines have limitations in correlating with clinical patients. Human induced pluripotent stem cells (hiPSCs) have the potential to overcome these limitations and expand GPCR research towards personalized medicine. This review discusses the challenges of detecting GPCRs in hiPSCs and summarizes existing and new labeling methods.
