Gprc6a Knockout AML12 Cell Line

The choice depends on whether you are studying Gprc6a's role as a metabolic GPCR sensing basic L-amino acids, osteocalcin, and testosterone or its functions in liver metabolism, β-cell function, and male reproductive biology. The Knockout line is the standard tool for asking whether Gprc6a is required for these processes — Gprc6a is a class C GPCR (related to CaSR, mGluRs) with established roles in sensing extracellular L-arginine, L-lysine, L-ornithine, undercarboxylated osteocalcin (a bone-derived hormone), and reported as a non-classical testosterone receptor in some studies. Overexpression is useful for studying Gprc6a in heterologous expression contexts. For liver metabolism research, the EDITGENE Gprc6a Knockout in AML12 is highly relevant — AML12 is a non-tumorigenic mouse hepatocyte cell line providing a physiologically relevant context for studying hepatic Gprc6a function in glucose/lipid metabolism. Rescue with wild-type or signaling-deficient Gprc6a enables structure-function studies. The knockout is valuable for studying amino acid-induced hepatic signaling, osteocalcin-hepatocyte axis, and emerging Gprc6a-targeted metabolic disease therapeutics.

Primary applications: • Basic L-amino acid sensing: cellular Ca²⁺ mobilization following L-arginine, L-lysine, L-ornithine stimulation in Gprc6a-null hepatocytes. • Osteocalcin signaling: undercarboxylated osteocalcin-induced signaling in hepatocyte context given the bone-liver axis. • Hepatic glucose metabolism: glucose production and glycolysis analysis given Gprc6a's role in hepatocyte amino acid sensing. • Discovery proteomics: phosphoproteomics in Gprc6a-null hepatocytes to identify candidate Gprc6a-dependent signaling events. EDITGENE recommends this AML12-based model for researchers investigating hepatic Gprc6a biology, osteocalcin-hepatocyte axis, and amino acid-induced metabolic signaling.

Yes. Gprc6a rescue experiments require attention to class C GPCR architecture: • Construct design: use a codon-modified Gprc6a sequence with a small intracellular C-terminal tag (FLAG, HA). Class C GPCRs have large extracellular Venus flytrap ligand-binding domain, cysteine-rich domain, and seven-transmembrane region — preserve all elements. • Signaling-deficient rescue: DRY motif or specific intracellular loop mutations disrupt G-protein coupling. • Surface localization validation: confirm plasma membrane localization by cell surface staining before functional assays. • Functional readout: rescue should restore basic L-amino acid-induced cellular signaling (Ca²⁺ mobilization, ERK activation) in hepatocyte context. AML12-specific considerations: • AML12 is a non-tumorigenic immortalized murine hepatocyte cell line (derived from TGF-α transgenic CD1 mouse liver) retaining hepatocyte differentiation features — the principal continuous mouse hepatocyte model for liver biology and metabolic research. • Lentiviral transduction is supported but may require optimization; characterize hepatocyte marker expression (albumin, transferrin) before phenotypic assays. • Specialized culture conditions are required (DMEM/F12 with insulin-transferrin-selenium-dexamethasone supplement).
