Summary of "A pH-Responsive Glycyrrhetinic acid-Modified Small Molecular Conjugate for NIR Imaging of Hepatocellular Carcinoma (HCC)."

Herein, we reported a glycyrrhetinic acid (GA)-decorated small molecule conjugate for pH-triggered near infra-red (NIR) fluorescence imaging of hepatocellular carcinoma (HCC). Our ''in vitro'' studies demonstrated that NIR-GA was efficiently up-taken by liver cancer cell lines such as HepG2 and Huh7 through GA receptors-mediated endocytic pathway. As suggested by co-localization studies, NIR-GA mainly localized into the lysosome where acidic pH results in activation of fluorescent dye via H+-triggered spirolactam ring opening to give strong fluorescence in NIR region.

Medical and Biotech [MESH] Definitions

The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.

Semisynthetic vaccines consisting of polysaccharide antigens from microorganisms attached to protein carrier molecules. The carrier protein is recognized by macrophages and T-cells thus enhancing immunity. Conjugate vaccines induce antibody formation in people not responsive to polysaccharide alone, induce higher levels of antibody, and show a booster response on repeated injection.

The use of combination of imaging techniques or platforms (e.g., MRI SCAN and PET SCAN) encompassing aspects of anatomical, functional, or molecular imaging methods.

An oleanolic acid from GLYCYRRHIZA that has some antiallergic, antibacterial, and antiviral properties. It is used topically for allergic or infectious skin inflammation and orally for its aldosterone effects in electrolyte regulation.

The use of light interaction (scattering, absorption, and fluorescence) with biological tissue to obtain morphologically based information. It includes measuring inherent tissue optical properties such as scattering, absorption, and autofluorescence; or optical properties of exogenous targeted fluorescent molecular probes such as those used in optical MOLECULAR IMAGING, or nontargeted optical CONTRAST AGENTS.
