Organic Compounds

Organic Compounds

All living things are formed mostly of carbon compounds called organic compounds. The category of organic compounds includes both natural and synthetic compounds that contain carbon. Although a single, precise definition has yet to be identified by the chemistry community, most agree that a defining trait of organic molecules is the presence of carbon as the principal element, bonded to hydrogen and other carbon atoms. However, some carbon-containing compounds such as carbonates, cyanides, and...

Elements and Compounds

Elements and Compounds

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.
Elements
Elements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...

Solubility of Ionic Compounds

Solubility of Ionic Compounds

Solubility is the measure of the maximum amount of solute that can be dissolved in a given quantity of solvent at a given temperature and pressure. Solubility is usually measured in molarity (M) or moles per liter (mol/L). A compound is termed soluble if it dissolves in water.

Coordination Compounds and Nomenclature

Coordination Compounds and Nomenclature

In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

Summary

Predicting drug-induced cholestasis risk early in development is crucial. This study uses long-term primary human hepatocyte cultures and transcriptomics to identify gene expression profiles that indicate a higher risk of drug-induced liver injury.

Area of Science:

Hepatology
Toxicology
Drug Development

Background:

Drug-induced cholestasis is a severe form of drug-induced liver injury.
Current preclinical models have limited predictive value for identifying cholestatic drug risks.
Early identification of compounds posing a cholestasis risk is vital for drug development.

Purpose of the Study:

To establish a predictive in vitro model for drug-induced cholestasis.
To identify gene expression profiles associated with cholestatic drug toxicity.
To improve early-stage drug safety assessment.

Main Methods:

Long-term culture of primary human hepatocytes in a 2D-sandwich configuration.
Exposure of hepatocyte cultures to drugs and subsequent RNA extraction.
Transcriptomic analysis using gene chip assays and Ingenuity Pathway Analysis (IPA) software.

Main Results:

Primary human hepatocytes can be maintained in long-term culture for toxicity studies.
Transcriptomics can identify gene expression signatures related to drug-induced cholestasis.
Specific genes involved in bile acid homeostasis were highlighted as potential biomarkers.

Conclusions:

Long-term primary human hepatocyte cultures offer a promising in vitro model for assessing drug-induced cholestasis.
Transcriptomic analysis of these cultures can predict individual susceptibility to drug-induced cholestasis.
This approach enhances the early detection of hepatotoxic compounds in drug development.
