AI Article Synopsis
Article Abstract
The cellular response evoked by a hexanuclear platinum complex, PtL (), is reported. Compound , a 3-nm octahedral cage formed by self-assembly of six Pt(II) centers and four 2,4,6-tris(4-pyridyl)-1,3,5-triazine ligands (L), exhibits promising in vitro potency against a panel of human cancer cell lines. Unlike classical platinum-based anticancer agents, interacts with DNA in a non-covalent, intercalative manner and promotes DNA condensation. In cancer cells, induces DNA damage, upregulates p53, its phosphorylated form phospho-p53 and its downstream effector, p21, as well as both apoptosis and senescence.

Five series of new 1,3,4-thiadiazole hybrids were designed and synthesized as promising EGFR inhibitors. Three human cancer cell lines were employed for testing each hybrid's in vitro antiproliferative efficacy; colon HCT-116, liver HepG-2 and breast MCF-7 using MTT assay. Comparing compound 9a to the reference doxorubicin, 9a shown superior activity to that of Dox with respect to MCF-7 (IC 3.

Berberine, an isoquinoline alkaloid derived from various medicinal plants, emerges as a potential therapeutic agent against diverse human diseases. It has particularly shown notable anticancer efficacy against breast, colorectal, lung, prostate, and liver cancer. Berberine results in inhibition of cancer cell proliferation, induction of apoptosis, and suppressing angiogenesis, positioning it as a versatile, multitargeted therapeutic tool against cancer.

Prebiotic dietary fiber (PDF) may reduce feelings of stress or improve mood in healthy individuals. Yet gut intervention studies that focus on mood in daily life are lacking and few studies include extensive biological sample analyses to gain mechanistic insights. As part of a larger randomized placebo-controlled crossover study including healthy individuals, we explored the effects of 12 weeks of PDF (acacia gum and carrot powder) on everyday mood, as measured with ecological momentary assessment (EMA).

Introduction: The plasma membrane-bound protein, multi-drug resistance-associated protein 4 (), has gained attention for its pivotal role in facilitating the efflux of a wide range of endogenous and xenobiotic molecules. Its significance in adipogenesis and fatty acid metabolism has been brought to light by recent studies. Notably, research on knockout ( ) mice has established a link between the absence of and the development of obesity and diabetes.

Background & Aims: Hepatic immune imbalance is crucial for driving metabolic dysfunction-associated steatotic liver disease (MASLD) progression. However, the role of hepatic regulatory T cells (Tregs) in MASLD initiation and the mechanisms responsible for their change are not completely understood.
Methods: A mouse model subjected to a short-term high-fat diet (HFD) to mimic early steatosis, along with liver biopsy samples from patients with simple steatosis, and macrophage-specific Notch1-knockout mice (Notch1), were used to investigate the role of Tregs in early MASLD and the effect of hepatic macrophage Notch1 signaling on Treg frequency.
