Cancer is a deadly disease caused by cells that deviate from the normal differentiation and proliferation behaviors and continue to multiply. There is still no definitive cure, and many side effects occur even after treatment. However, apoptosis, one of the programs imprinted on cells, is becoming an important concept in controlling cancer.

Article Synopsis
  • The activation of human immune cells by intestinal microorganisms, like probiotics and prebiotics, is crucial for maintaining a healthy balance between beneficial and harmful bacteria in the gut.
  • Probiotic products are becoming popular, especially for skin health and managing atopic dermatitis (AD), which is linked to immune system reactions and inflammation.
  • A study on anti-atopic substances showed that treatment reduced symptoms of AD by decreasing skin inflammation and improving immune responses, as observed through various tests on experimental animals.

Inflammatory bowel disease (IBD) is a chronic inflammatory condition caused by the disruption of the intestinal barrier. The intestinal barrier is maintained by tight junctions (TJs), which sustain intestinal homeostasis and prevent pathogens from entering the microbiome and mucosal tissues. Miller () is a natural substance that has been used in traditional medicine as a therapy for a variety of diseases.

In this study, we investigated the hepatoprotective effects of an ethanol extract of Aiton (ESF) on an alcohol-induced liver disease mouse model. Alcoholic liver disease (ALD) was caused by the administration of ethanol to male C57/BL6 mice who were given a Lieber-DeCarli liquid diet, including ethanol. The alcoholic fatty liver disease mice were orally administered ESF (100 and 200 mg/kg bw/day) or silymarin (50 mg/kg bw/day), which served as a positive control every day for 16 days.

Hepatocellular carcinoma (HCC) stands as a leading cause of mortality, and despite recent advancements in the overall survival rates, the prognosis remains dismal. Prunetin 4-O-glucoside (Prunetrin or PUR), an active compound derived from Prunus sp., was explored for its impact on HepG2 and Huh7 cells.

Docetaxel (DTX), a semi-synthetic analogue of paclitaxel (taxol), is known to exert potent anticancer activity in various cancer cells by suppressing normal microtubule dynamics. In this study, we examined how the anticancer effect of DTX is regulated by polyphenols extracted from Korean L. (pKAL) in DU145 prostate cancer cells (mutant p53) and HCT116 colorectal cancer cells (wild-type p53).

Recent studies suggest that the anticancer activity of β-lapachone (β-Lap) could be improved by different types of bioactive phytochemicals. The aim of this study was to elucidate how the anticancer effect of β-Lap is regulated by polyphenols extracted from Korean L. (pKAL) in parental HCT116 and oxaliplatin-resistant (OxPt-R) HCT116 colorectal cancer cells.

Neuromuscular diseases (NMDs) are a genetically or clinically heterogeneous group of diseases that involve injury or dysfunction of neuromuscular tissue components, including peripheral motor neurons, skeletal muscles, and neuromuscular junctions. To study NMDs and develop potential therapies, remarkable progress has been made in generating in vitro neuromuscular models using engineering approaches to recapitulate the complex physical and biochemical microenvironments of 3D human neuromuscular tissues. In this review, we discuss recent studies focusing on the development of in vitro co-culture models of human motor neurons and skeletal muscles, with the pros and cons of each approach.

The phenolic compounds in Lonicera japonica & Chenpi distillation extract (LCDE) were thoroughly examined for their antioxidant and anti-inflammatory properties. Phenolic compounds in LCDE were analyzed for five peaks using high-performance liquid chromatography (HPLC) combined with mass spectrometry (MS) and determined. Five phenolic compounds were identified from the samples and MS data.

β-lapachone (β-Lap), a topoisomerase inhibitor, is a naturally occurring -naphthoquinone phytochemical and is involved in drug resistance mechanisms. Oxaliplatin (OxPt) is a commonly used chemotherapeutic drug for metastatic colorectal cancer, and OxPt-induced drug resistance remains to be solved to increase chances of successful therapy. To reveal the novel role of β-Lap associated with OxPt resistance, 5 μM OxPt-resistant HCT116 cells (HCT116-OxPt-R) were generated and characterized via hematoxylin staining, a CCK-8 assay and Western blot analysis.
