GALA	Exosomes Liposome	Cancer
GALA is a pH-responsive amphipathic peptide consisting of 30 amino acids, which acts as a lung endothelium-targeting ligand.

GALA-modified liposomes traverse lung endothelial cells via clathrin-dependent endocytosis and transcytosis, and specifically accumulate in the lungs after intravenous injection. GALA significantly promotes the cytosolic release of cargos carried by exosomes, plasmids and liposomes, effectively enhances gene transfection efficiency, and drives gene knockdown of functional macromolecules (such as siRNA) in alveolar epithelial cells (with no significant cytotoxicity at effective concentrations). GALA serves as a critical tool for studies on lung cancer metastasis (e.g., melanoma lung metastasis) and lung-targeted drug delivery systems .

GALA	Exosomes Liposome	Cancer
GALA is a pH-responsive amphipathic peptide consisting of 30 amino acids, which acts as a lung endothelium-targeting ligand. GALA undergoes a conformational transition from random coil to α-helix in an acidic environment at pH 5.0, thereby inducing endosomal membrane destabilization and fusion. GALA-modified liposomes traverse lung endothelial cells via clathrin-dependent endocytosis and transcytosis, and specifically accumulate in the lungs after intravenous injection. GALA significantly promotes the cytosolic release of cargos carried by exosomes, plasmids and liposomes, effectively enhances gene transfection efficiency, and drives gene knockdown of functional macromolecules (such as siRNA) in alveolar epithelial cells (with no significant cytotoxicity at effective concentrations). GALA serves as a critical tool for studies on lung cancer metastasis (e.g., melanoma lung metastasis) and lung-targeted drug delivery systems .

Urinary concentrations of AalphaC are significantly higher in dedicated smokers than in non-smokers, indicating its importance in monitoring tobacco exposure. AalphaC levels increase significantly with increasing serum nicotine levels, indicating its close relationship with tobacco use. In addition, consuming high-temperature cooked beef significantly increases the amount of AalphaC in urine, while consuming vegetables is associated with a decrease in AalphaC concentrations. Smoking half a pack of cigarettes is associated with a significant increase in the amount of AalphaC, which further confirms the biological activity of AalphaC and its association with dietary habits .

Dodecanoylcarnitine 1 Publications Verification (-)-Lauroylcarnitine		Cationic Lipids
Dodecanoylcarnitine ((-)-Lauroylcarnitine) is a medium long-chain acylcarnitine, an intermediate product in key energy metabolic pathways of fatty acid β-oxidation and amino acids catabolism. The abnormal decrease in the Dodecanoylcarnitine levels indicats that mitochondrial fuel metabolism, including fatty acid oxidation is significantly disturbed. Changes in plasma concentrations of Dodecanoylcarnitine are not only associated with type II diabetes, but also with pre-diabetes status. Dodecanoylcarnitine is present in fatty acid oxidation disorders such as long-chain acyl CoA dehydrogenase deficiency, carnitine palmitoyltransferase I/II deficiency, and is also associated with celiac disease. Dodecanoylcarnitine deomonstrates high sensitivities and specificities in predicting asthma. Combined model of Decanoylcarnitine (HY-113069), Dodecanoylcarnitine, PC (16:0/0:0), and Asp Arg Pro can be used as a potential biomarker for the diagnosis of Yin-deficiency-heat syndrome .
