Elucidation of the molecular mechanisms by which 5-fluorouracil (5-FU) induces apoptosis is required in order to understand the resistance of colorectal cancer (CRC) cells to 5-FU. In the current study, 5-FU-induced apoptosis was assessed using the propidium iodide method. Involvement of protein kinase C (PKC) was assessed by evaluating the extent of their activation in CRC, following treatment...
5-Fluorouracil (5-FU) is an anticancer drug widely used in the treatment of colorectal cancers. In this work, long-circulating liposomes (LCL) were proposed as carriers able to improve the therapy with 5-FU. The objective was to optimize the formulation of 5-FU-loaded long circulating liposomes (LCL-5-FU) using the method of experimental design and to evaluate the in vitro drug release and cyto...
Acquired drug resistance (ADR) can be developed in colorectal cancer cells after 5-fluorouracil (5-FU) treatment and diminish the effectiveness of chemotherapy. In this work, acquired 5-FU resistance in the colorectal cancer cell line SW480 was obtained with the up-regulation of dihydropyrimidine dehydrogenase (DPYD) gene expression which can convert 5-FU to its inactive metabolite. To overcome...
MicroRNAs (miRNAs) are a conserved class of small non-coding RNAs that play important roles in diverse biological processes, including chemoresistance. However, the molecular mechanism as to how miR-203 modulates the chemosensitivity to 5-fluorouracil (5-FU) in colorectal cancer is poorly known. In the present study, we found that miR-203 was downregulated in the 5-FU-resistant cell line LoVo/5...
Although 5-fluorouracil (5-FU) is one of the most commonly used chemotherapeutic agents in various cancer including hepatocellular carcinoma (HCC), chemoresistance has precluded single use of 5-FU in clinical settings. Since menatetrenone, an analogue of vitamin K2 (VK2), inhibits growth of cancer cells including HCC cells in vitro and in vivo, we examined VK2 modulation of HCC cell response to...
This study assessed the protective effect of Zizphus jujube (ZJ) extract on 5‑FU‑induced alterations in renal function markers and kidney morphology Dawley rats. Twenty-four rats were divided randomly into four groups administrated orally with 0.9% normal saline as control group, 5-FU (40 mg/kg daily for 5 days), ZJ (500 mg/ kg 5-FU+ (for 6 days). further biochemical experiments carried out blo...
Five-fluorouracil (5-FU) is a widely used chemotherapeutic agent for digestive system tumors; however, continuous use of 5-FU may cause severe side effects, including myelosuppression and immunosuppression. Our previous study revealed that calcineurin B subunit (CnB), an innovative genetic engineering antitumor protein, possesses tumor-suppressive effects with low toxicity. CnB can bind to and ...
The role of the calcium binding protein, Calbindin 2 (CALB2), in regulating the response of colorectal cancer (CRC) cells to 5-Fluorouracil (5-FU) was investigated. Real-time RT-PCR and Western blot analysis revealed that CALB2 mRNA and protein expression were down-regulated in p53 wild-type and p53 null isogenic HCT116 CRC cell lines following 48 h and 72 h 5-FU treatment. Moreover, 5-FU-induc...
5-Fluorouracil (5-FU) is a widely used chemotherapeutic drug in colorectal cancer. Previous studies showed that 5-FU modulates RNA metabolism and mRNA expression. In addition, it has been reported that 5-FU incorporates into the RNAs constituting the translational machinery and that 5-FU affects the amount of some mRNAs associated with ribosomes. However, the impact of 5-FU on translational reg...
