Luteolin ameliorates chronic stress-induced depressive-like behaviors in mice by promoting the Arginase-1 microglial phenotype via a PPARγ-dependent mechanism.

Accumulating evidence shows that neuroinflammation substantially contributes to the pathology of depression, a severe psychiatric disease with an increasing prevalence worldwide. Although modulating microglial phenotypes is recognized as a promising therapeutic strategy, effective treatments are still lacking. Previous studies have shown that luteolin (LUT) has anti-inflammatory effects and confers benefits on chronic stress-induced depression.

Deep learning enables the discovery of a novel cuproptosis-inducing molecule for the inhibition of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most common and deadly cancers in the world. The therapeutic outlook for HCC patients has significantly improved with the advent and development of systematic and targeted therapies such as sorafenib and lenvatinib; however, the rise of drug resistance and the high mortality rate necessitate the continuous discovery of effective targeting agents. To discover novel anti-HCC compounds, we first constructed a deep learning-based chemical representation model to screen more than 6 million compounds in the ZINC15 drug-like library.

Single-cell transcriptomic dissection of the cellular and molecular events underlying the triclosan-induced liver fibrosis in mice.

Background: Triclosan [5-chloro-2-(2,4-dichlorophenoxy) phenol, TCS], a common antimicrobial additive in many personal care and health care products, is frequently detected in human blood and urine. Therefore, it has been considered an emerging and potentially toxic pollutant in recent years. Long-term exposure to TCS has been suggested to exert endocrine disruption effects, and promote liver fibrogenesis and tumorigenesis.

Identification of antimalarial targets of chloroquine by a combined deconvolution strategy of ABPP and MS-CETSA.

Background: Malaria is a devastating infectious disease that disproportionally threatens hundreds of millions of people in developing countries. In the history of anti-malaria campaign, chloroquine (CQ) has played an indispensable role, however, its mechanism of action (MoA) is not fully understood.

Methods: We used the principle of photo-affinity labeling and click chemistry-based functionalization in the design of a CQ probe and developed a combined deconvolution strategy of activity-based protein profiling (ABPP) and mass spectrometry-coupled cellular thermal shift assay (MS-CETSA) that identified the protein targets of CQ in an unbiased manner in this study.

Celastrol mitigates inflammation in sepsis by inhibiting the PKM2-dependent Warburg effect.

Background: Sepsis involves life-threatening organ dysfunction and is caused by a dysregulated host response to infection. No specific therapies against sepsis have been reported. Celastrol (Cel) is a natural anti-inflammatory compound that shows potential against systemic inflammatory diseases.

Artesunate synergizes with sorafenib to induce ferroptosis in hepatocellular carcinoma.

Sorafenib is the first-line medication for advanced hepatocellular carcinoma (HCC), but it can only extend limited survival. It is imperative to find a combination strategy to increase sorafenib efficacy. Artesunate is such a preferred candidate, because artesunate is clinically well-tolerated and more importantly both drugs can induce ferroptosis through different mechanisms.

Skeletal meroterpenoids from Ganoderma petchii mushrooms that potentially stimulate umbilical cord mesenchymal stem cells.

(±)-Petchilactones A-C (1-3), three pairs of enantiomeric meroterpenoids respectively with a 6/6/5/5 or a 5/5/5/7/6 ring system were isolated from Ganoderma petchii. Their structures including absolute configurations were assigned by using spectroscopic, computational, and X-ray diffraction methods. Compounds 1 and 2 represent a new skeletal meroterpenoid.

We conducted a hospital-based case-control study in 56 patients with breast cancer and 46 patients with benign breast disease. We detected the accumulation level of several organochlorine pesticides products (β-hexachlorocyclohexane, γ-hexachlorocyclohexane, polychlorinated biphenyls-28, polychlorinated biphenyls-52, pentachlorothioanisole, and pp'-dichlorodiphenyldichloroethane) in breast adipose tissues of all 102 patients using gas chromatography.

HCRP1 inhibits TGF-β induced epithelial-mesenchymal transition in hepatocellular carcinoma.

Hepatocellular carcinoma-related protein 1 (HCRP1), also known as human vacuolar protein sorting 37 homologue A (hVps37A), has not been detected or is significantly downregulated in hepatocellular carcinoma (HCC) tissues. However, information on the regulatory mechanisms of HCRP1 in HCC remains unclear. Here we found that the downregulation of HCRP1 in HepG2 cells (with low invasion capacity) significantly enhanced migration and invasion, whereas HCRP1 upregulation in SMMC-7721 cells (with high invasion capacity) generated the opposite result.
