Many cultures worldwide have widely used traditional medicine (TM) to prevent or treat diseases. Herbal materials and their compounds used in TM offer many advantages for drug discovery, including cost-effectiveness, fewer side effects, and improved metabolism. However, the multi-compound and multi-target characteristics of TM prescriptions complicate drug discovery; meanwhile, previous studies have been limited by a lack of high-quality data, complex interpretation, and/or narrow analytical ranges.

Unlabelled: Menopausal symptoms, including hot flashes, metabolic changes, and osteoporosis, significantly impact postmenopausal women. Given concerns about hormone replacement therapy, S-equol, a metabolite of the soybean isoflavone daidzein, has emerged as a potential alternative. This study explored the efficacy of S-equol-containing-supplement (SE5-OH), a fermented soy germ containing S-equol, on menopausal symptoms and osteoporosis in 6-month-old and 8-week-old ovariectomized (OVX) rat models.

Despite the increasing global demand for functional foods, the challenges associated with bioactive natural food products due to their complex composition remain. Bioactive natural products can potentially interfere with physiological activity regulation and lead to undesired side effects. This finding emphasizes the need for machine learning (ML)-based food safety predictions focused on intrinsic toxicity.

(PK) leaf extract, derived from Korean pine byproducts, holds promise for alleviating postprandial hyperlipidemia. In this study, we investigated the potential of PK leaf extract for modulating postprandial hyperlipidemia in adults with normal or borderline fasting triglyceride levels. In a randomized, double-blind, parallel design, 70 subjects were randomly assigned to either the placebo or PK group for 4 weeks.

Unlabelled: The natural byproduct was widely used in ancient Asia to cure disease because of its various pharmacological effects. Despite its ethnomedicinal benefits, few studies on the intestinal anti-inflammatory effect of have been reported. Therefore, this study aimed to evaluate the potential beneficial effects of on the intestine in vitro and in vivo.

Many mitotic kinases have been targeted for the development of anti-cancer drugs, and inhibitors of these kinases have been expected to perform well for cancer therapy. Efforts focused on selecting good targets and finding specific drugs to target are especially needed, largely due to the increased frequency of anti-cancer drugs used in the treatment of lung cancer. Vaccinia-related kinase 1 (VRK1) is a master regulator in lung adenocarcinoma and is considered a key molecule in the adaptive pathway, which mainly controls cell survival.

To date, many anticancer drugs have been developed by directly or indirectly targeting microtubules, which are involved in cell division. Although this approach has yielded many anticancer drugs, these drugs produce undesirable side effects. An alternative strategy is needed, and targeting mitotic exit may be one alternative approach.

Article Synopsis
  • Cholangiocarcinoma (CC) is a deadly bile duct cancer with poor survival rates, characterized by aggressive spread and a process called epithelial mesenchymal transition (EMT).
  • The study focused on understanding genetic changes and gene expression linked to the aggressive form of CC, using four established human cell lines (SCK, JCK1, Cho-CK, and Choi-CK) with varying differentiation levels.
  • Key findings included a deletion of the p53 tumor suppressor gene in the aggressive SCK cells and significant differences in the expression levels of 260 over-expressed and 247 under-expressed genes in comparison to well-differentiated cells, indicating a connection between these genetic changes and the aggressive behavior of
