Chemicals (such as alcohol, drugs, and pollutants) may cause liver injuries, which could consequently develop into fatty liver, hepatitis, fibrosis, cirrhosis, and liver failure, or even cancers. Liver injuries have been a serious public health problem worldwide. Numerous natural products and their bioactive components have shown protective action for liver injuries, such as blueberry, cactus fruits, Pueraria lobate, betaine, and silymarin. The underlying mechanisms mainly include antioxidation, anti-inflammation, anti-apoptosis, anti-necrosis, repairing damaged DNA, regulating the metabolism of lipids, and modulating primary bile acid biosynthesis. This review summarizes the natural products and bioactive compounds with protective effects on liver injuries caused by chemicals, and special attention is paid to the mechanisms of action. This updated information can be helpful to prevent and treat liver-related diseases, especially chemical-induced liver injuries.

Objective: To describe the presentation, outcomes, and management strategies for cases of subcapsular liver hematoma associated with preeclampsia, eclampsia, or HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome.
Methods: This was a case series of individuals with subcapsular liver hematoma managed at a single level IV center over a 10-year period, from 2013 to 2024. Presenting signs and symptoms, laboratory findings, time of onset, management strategies, acute perinatal and maternal outcomes, and long-term outcomes such as subsequent pregnancies were reviewed in the medical record and recorded.

The liver is a highly regenerative organ capable of significant proliferation and remodeling during homeostasis and injury responses. Experiments of nature in rare genetic diseases have illustrated that healthy hepatocytes may have a selective advantage, outcompete diseased cells, and result in extensive liver replacement. This observation has given rise to the concept of therapeutic liver repopulation by providing an engineered selective advantage to a subpopulation of beneficial hepatocytes.

Vanin-1 is a pantetheine hydrolase that plays a key role in inflammatory diseases. Effective tools for noninvasive, real-time monitoring of Vanin-1 are lacking, largely due to background fluorescence interference in existing probes. To address this issue, we developed a dual-modal fluorescent and colorimetric probe, MB-Van1, to detect Vanin-1 with high sensitivity and selectivity.

Drug-induced liver injury (DILI) is a major challenge in drug development, often leading to clinical trial failures and market withdrawals due to liver toxicity. This study presents StackDILI, a computational framework designed to accelerate toxicity assessment by predicting DILI risk. StackDILI integrates multiple molecular descriptors to extract structural and physicochemical features, including the constitution, pharmacophore, MACCS, and E-state descriptors.

The frequency of drug-induced liver injury (DILI) in clinical trials remains a challenge for drug developers despite advances in human hepatotoxicity models and improvements in reducing liver-related attrition in preclinical species. TAK-994, an oral orexin receptor 2 agonist, was withdrawn from phase II clinical trials due to the appearance of severe DILI. Here, we investigate the likely mechanism of TAK-994 DILI in hepatic cell culture systems examined cytotoxicity, mitochondrial toxicity, impact on drug transporter proteins, and covalent binding.
