Although gomisin A (GA) alleviates cancer and inflammation, its anti-obesity effect and the underlying mechanism have not yet been elucidated. Therefore, in this study, we aimed to elucidate the anti-obesity effects of GA by investigating the phenotypic changes involved in the browning and whitening of adipocytes. Here, obesity was induced to C57BL/6J mice using a high-fat diet (HFD).

Background: Despite the rising 5-year survival rate of colorectal cancer (CRC) patients, the survival rate decreases as the stage progress, and a low survival rate is highly associated with metastasis.

Purpose: The purpose of our study is to investigate the effect of dehydroevodiamine (DHE) on the lung metastasis of CRC and the proliferation of CRC cells.

Study Design: Cell death was confirmed after DHE treatment on several CRC cell lines.

Article Synopsis
  • - Colorectal cancer (CRC) is a leading cause of cancer deaths globally, and this study explored the effects of gallotannin (GT), a natural compound, on metastatic CRC cells.
  • - GT was found to significantly reduce the viability of various metastatic CRC cell lines through mechanisms like inducing cell death, disrupting the cell cycle, and promoting autophagy.
  • - The compound also inhibited cancer cell migration and invasion by affecting crucial signaling pathways and lowering the levels of proteins involved in metastasis, suggesting it could be a potential therapeutic agent against metastatic CRC.

Recent research suggests a relationship between cancer progression and oxidative mechanisms. Among the phenolic compounds such as tracheloside (TCS) are a major bioactive compound that can combat oxidant stress-related chronic diseases and that also displays anti-tumor activity. Although TCS can inhibit mammalian carcinoma, its effects on colorectal cancer (CRC) have not been clarified.

Article Synopsis
  • Miquel is an unripe black raspberry native to eastern Asia, traditionally used for medicinal purposes, with its extract (RCE) showing diverse biological activities but unclear effects on antitumor immunity and T cell function.
  • The study examines the anti-tumor effects of RCE by blocking the PD-1/PD-L1 interaction in humanized mice with colorectal tumors, using various assays to analyze binding properties and cellular activities.
  • Findings indicate that RCE and its main component, ellagic acid, effectively block PD-1 from binding to PD-L1 and exhibit significant anti-tumor activity, suggesting RCE's potential as an immunotherapeutic agent.

Background: Cachexia induced by cancer is a systemic wasting syndrome and it accompanies continuous body weight loss with the exhaustion of skeletal muscle and adipose tissue. Cancer cachexia is not only a problem in itself, but it also reduces the effectiveness of treatments and deteriorates quality of life. However, effective treatments have not been found yet.

Pancreatic cancer (PC) is one of the most severe cancers, and its incidence and mortality rates have steadily increased in the past decade. In this study, we demonstrate the effect of Nakai extract on pancreatic ductal adenocarcinoma cells. We prepared Nakai ethanol extract (AGE) using roots of Nakai and detected its active compound decursin from AGE by ultra-performance liquid chromatography analysis.

Article Synopsis
  • - Gomisin A (G.A), derived from Schisandra chinensis, exhibits anti-tumor properties, especially against hepatocarcinoma and colorectal cancer; this study explores its effects on metastatic melanoma.
  • - The research demonstrated that G.A reduces melanoma cell viability by inducing cell cycle arrest and apoptosis and is influenced by AMPK, ERK, and JNK activation.
  • - G.A effectively inhibits melanoma cell migration and invasion through suppression of epithelial-mesenchymal transition (EMT) and shows promise in reducing lung metastasis.

Background: Colorectal cancer (CRC) is one of the diseases with high prevalence and mortality worldwide. In particular, metastatic CRC shows low probability of surgery and lacks proper treatment. In this study, we conducted experiments to investigate the inhibitory effect of betulin against metastatic CRC and related mechanisms.

Pancreatic cancer (PC) is one of the most aggressive malignancies in the world. Gemcitabine (Gem), a nucleoside pyrimidine analogue, is a first-line chemotherapeutic drug for PC, but the tumor response rate of Gem is very low and resistance to Gem has emerged as a major problem in the treatment of PC. Oat bran, used as animal and human food, has been found to be beneficial to health.

Background: Although rubrofusarin-6-β-gentiobioside (RFG), which is a component of Cassiae tora seed, could likely regulate hyperlipidemia, its anti-obesity effect and related mechanism have not been elucidated.

Purpose: The aim of this study was to examine whether RFG can ameliorate obesity and the mechanism of lipid accumulation regulated by RFG.

Study Design: In in vitro experiments, we confirmed the anti-adipogenic effect of RFG using 3T3-L1 cells and human adipose mesenchymal stem cells (hAMSCs).

Background: In colorectal cancer (CRC), 40-60% of patients develop metastasis. The epithelial-mesenchymal transition (EMT) is a pivotal and intricate process that increases the metastatic potential of CRC. The aim of this study was to investigate the effect of Korean Red Ginseng extract (RGE) on colorectal metastasis through inhibition of EMT and the metastatic abilities of CRC cells.

Ethnopharmacological Relevance: The pharmacological effect derived from herb-herb interaction is important to constitute the prescription especially in traditional oriental medicine. The relationship of two medicinal herbs is called "couplet medicinals" which is used in pair for the purpose of enhancing the therapeutic effect, reducing the toxic effect or the adverse effect. The "Eighteen Incompatible Medicaments" constitute one of the contents in the incompatibility of traditional oriental drugs in a prescription.

Rosmarinic acid (RA) has been used as an anti-inflammatory, anti-diabetic, and anti-cancer agent. Although RA has also been shown to exert an anti-metastatic effect, the mechanism of this effect has not been reported to be associated with AMP-activated protein kinase (AMPK). The aim of this study was to elucidate whether RA could inhibit the metastatic properties of colorectal cancer (CRC) cells via the phosphorylation of AMPK.

Although Arctii Fructus (AF) has been shown to have various pharmacological effects, there have been no studies concerning the inhibitory effects of AF on the metastatic properties of colorectal cancer (CRC). The aim of this study was to investigate whether AF could suppress CRC progression by inhibiting cell growth, epithelial-mesenchymal transition (EMT), migration, and the invasion ability of CRC cells. AF decreased proliferation of CRC cells by inducing cell cycle arrest and apoptosis via extrinsic and intrinsic apoptotic pathways.

Eclipta prostrata (EP) and its compounds are known to have several pharmacological effects including anti-inflammatory effects. In the present study, we demonstrated that EP improves the dextran sulfate sodium (DSS)-induced colitis symptoms such as body weight loss, colon length shortening and disease activity index. In DSS-induced colitis tissue, EP controls the protein expressions of cyclooxygenase-2 (COX-2) and hypoxia inducible factor-1[Formula: see text] (HIF-1[Formula: see text]).
