Overview of Gene Research
Rgs1, short for Regulator of G-protein signaling 1, is involved in regulating G-protein-coupled receptor (GPCR) signaling. By accelerating the hydrolysis of GTP to GDP on the Gα subunit of heterotrimeric G-proteins, it turns off GPCR-mediated signaling pathways. This regulation is crucial for various cellular processes such as cell communication, signal transduction, and cell response to stimuli [7].
In acute lung injury/acute respiratory distress syndrome (ALI/ARDS) and pulmonary fibrosis (PF), epithelium-and endothelium-derived exosomes target RGS1, which coregulates the immunophenotype of alveolar macrophage subpopulations through the PLC-IP3R signal-dependent intracellular Ca2+ response. Imbalance of alveolar macrophages due to lack of relevant exosome secretion is related to these diseases, and treatment with exosomes can improve the conditions [1]. In renal interstitial fibrosis (RIF), RGS1 expression is elevated. Knockdown of RGS1 inhibits renal cell inflammatory response, fibrosis, and renal fibrosis in RIF mice, suggesting it as a potential therapeutic target [2]. In cervical cancer, RGS1 is an oncogenic gene affecting the immune microenvironment, and its knockdown can inhibit cell proliferation, migration, invasion, and tumor growth in nude mice [3]. In gastric cancer, silencing the RGS1 gene reduces the proliferation of drug-resistant cells in vitro and inhibits tumor growth in vivo, serving as an antitumor target [4]. In osteosarcoma, RGS1 is a tumor-promoting gene, and microRNA-376b-3p can target it to inhibit cell proliferation, metastasis, and apoptosis [6]. In spinal cord injury, RGS1 knockdown suppresses TLR-signaling-pathway-induced inflammation, inhibits MMP-induced tissue degradation, and improves spinal cord histology and function recovery [5].
In summary, Rgs1 plays diverse roles in multiple biological processes and disease conditions. Through gene-knockout (KO) or conditional-knockout (CKO) mouse models and other loss-of-function experiments, it has been revealed that Rgs1 is involved in immune regulation, fibrosis, and tumor-related processes. These findings provide potential therapeutic strategies for diseases like ALI/ARDS, PF, RIF, cervical cancer, gastric cancer, osteosarcoma, and spinal cord injury.
