A green method was used for producing gold nanoparticles (Au NPs) using chitosan as a natural cationic, biodegradable and biocompatible polymer. In this method, chitosan acts as a reducing and stabilizing agent for the synthesis of Au NPs. Different concentrations of chitosan solutions (0.01%, 0.05%, 0.1%, 0.2%, 0.5% and 1%) were applied. In an attempt to mitigate the side effects of anti-cancer drug, 5-fluorouracil (5-FU), through reducing drug doses in photothermal therapy, the formed positively-charged chitosan-wrapped Au NPs were used as a drug delivery system for negatively charged 5-FU to hepatocellular carcinoma cells (HepG2)...

Chemotherapy concurrent with radiotherapy has been widely used in clinical practice because the additional benefit on radiotherapy alone had shown. Head and neck cancer: CDDP concurrent with radiotherapy has been a standard treatment for 15years both in definitive setting and postoperative setting. Esophageal cancer: 5-FU/CDDP is the best partner for radiotherapy and appropriate radiation dose has been discussed. Anal cancer: Radical concurrent chemoradiotherapy with 5-FU and mitomycin C(MMC)remains the standard of care for squamous cell carcinoma of the anus...

Systemic chemotherapy based on 5-fluorouracil(5-FU)is a standard treatment for unresectable or recurrent colon cancers. Here, we report a case of hyperammonemia induced by chemotherapy using 5-FU for metastatic colon cancer. An 84-yearold male patient with past histories of liver cirrhosis related to hepatitis C virus and renal dysfunction underwent an operation for the rectosigmoid colon cancer 8 years ago. Three years after that operation, a local recurrence of the colon cancer was diagnosed, and chemotherapy using sLV5FU2 was initiated...

Adjuvant chemotherapy is used for human breast cancer patients, even after curative surgery of primary tumor, in order to prevent tumor recurrence primarily as a form of metastasis. However, anti-cancer drugs can accelerate metastasis in several mouse metastasis models. Hence, we examined the effects of post-surgical administration with 5-fluorouracil (5-FU), doxorubicin, and cyclophosphamide, on lung metastasis process, which developed after the resection of the primary tumor arising from the orthotopic injection of a mouse triple-negative breast cancer cell line, 4T1...

Colorectal cancer is one of the most common causes of cancer death worldwide. In patients with metastatic colorectal cancer, combination treatment with several anti-cancer drugs is employed and improves overall survival in some patients. Nevertheless, most patients with metastatic disease are not cured owing to the drug resistance. Cancer stem cells are known to regulate resistance to chemotherapy. In the previous study, we established a novel three-dimensional organoid culture model from tumor colorectal tissues of human patients using an air-liquid interface (ALI) method, which contained numerous cancer stem cells and showed resistance to 5-fluorouracil (5-FU) and Irinotecan...

2',4'-Dihydroxy-6'-methoxy-3',5'-dimethylchalcone (DMC) is a major active constituent of the buds of Cleistocalyx operculatus (Roxb.) Merr. et Perry (Myrtaceae), a main ingredient of herbal tea in tropical zones. DMC has been reported to significantly reverse drug resistance in BEL-7402/5-FU cells. Glutathione (GSH) and glutathione S-transferase (GST) play important roles in an efflux system that protects the cells from anticancer drugs. In this study, DMC remarkably decreased the intracellular GSH content and GST activity...

It has been demonstrated that β‑arrestin2 is involved in the initiation and development of many types of cancers. However, its role in colorectal cancer (CRC) remains poorly understood. The present study investigated the role of β‑arrestin2 in CRC using CRC patient tissues as well as the LoVo and HCT116 CRC cell lines. Briefly, significantly higher expression of β‑arrestin2 was observed in CRC tissues compared with normal colon tissues. In addition, the downregulation of β‑arrestin2 reduced 5‑FU‑induced apoptosis in the LoVo cells, while the overexpression of β‑arrestin2 increased the apoptosis of HCT116 cells in vitro...

BACKGROUND Triple negative breast cancer (TNBC) has a more aggressive recurrence. Previous reports have demonstrated that sphingosine kinase 1 (SphK1) is a crucial regulator of breast cancer progression. However, the correlation of SphK1 with clinical prognosis has been poorly investigated. Thus, we aimed to elaborate the role of SphK1 in TNBC metastasis. MATERIAL AND METHODS We first determined the level of SphK1 in breast cancer tissue samples and breast cancer cells. Furthermore, the expression of HER2 and phosphor-SphK1 (pSphK1) in human breast cancer tissue samples was determined by immunohistochemical analysis...
