Curcumin, which is extracted from the plant Curcuma longa, has been used in the therapeutic arsenal for clinical oncology. Curcumin has chemopreventive and antitumoral activities against some aggressive and recurrent cancers. The expressions and activities of various proteins, such as inflammatory cytokines and enzymes, transcription factors, and gene-products linked with cell survivals and pro...
Curcumin is a multifunctional and natural agent considered to be pharmacologically safe. However, its application in the food and medical industry is greatly limited by its poor water solubility, physicochemical instability and inadequate bioavailability. Nanoliposome encapsulation could significantly enhance the solubility and stability of curcumin. Curcumin nanoliposomes exhibited good physic...
AIM Curcumin has been demonstrated to have antitumor effects including radiosensitization by modulating many molecular targets including p53. Herein, we investigated the radiosensitizing effect of curcumin in p53 mutant Ewing's sarcoma (ES) cells. MATERIALS AND METHODS Cells exposed to radiation with or without curcumin were examined for transcriptional and translational levels of p53 downstr...
Curcumin is a major constituent of the spice turmeric and has various biological activities, including anticancer, antioxidant, and anti-inflammatory properties, as well as alcohol detoxification. However, because of its poor absorption efficiency, it is difficult for orally administered curcumin to reach blood levels sufficient to exert its bioactivities. To overcome this problem, several curc...
Curcumin (diferuloylmethane) is an active component of the spice turmeric and has a diversity of antitumor activities. In this study, we found that curcumin can inhibit cancer cell invasion and metastasis through activation of the tumor suppressor DnaJ-like heat shock protein 40 (HLJ1). Human lung adenocarcinoma cells (CL1-5) treated with curcumin (1-20 mumol/L) showed a concentration-dependent...
objective: curcumin is extracted from curcuma longa and regulates the intracellular signal pathways which control the growth of cancerous cell, inflammation, invasion and apoptosis. curcumin molecules have special intrinsic features that can target the intracellular enzymes, genome (dna) and messengers (rna). a wide range of studies have been conducted on the physicochemical traits and pharmaco...
We investigated the impact of curcumin on neutrophils. Chemotactic activity via human recombinant IL-8 (hrIL-8) was significantly inhibited by curcumin. Curcumin reduced calcium ion flow induced by internalization of the IL-8 receptor. We analyzed flow cytometry to evaluate the status of the IL-8 receptor after curcumin treatment. The change in the distribution of receptors intracellularly and ...
To the Editor: The recent article by Dhillon et al. (1) is of great interest to those working with curcumin. As the investigators suggest, the usefulness of curcumin could be minimized because of its poor oral bioavailability (2). Data from this study show that only 22 to 41 ng/mL were detectable in plasma even when 8 g curcumin/day was given orally (1). Curcumin levels in the microgram range h...
Curcumin is a polyphenolic phytonutrient that has antineurodegenerative properties. In this study, we investigated the anti-amyloidogenic properties of curcumin. Following incubation with curcumin, intrinsic tryptophan fluorescence emission of apolipoprotein (apo) A-I was strongly quenched. At the same time, curcumin fluorescence emission was enhanced. The fluorescence emission spectra of curcu...
Chronic use of opioid analgesics has been hindered by the development of opioid addiction and tolerance. We have reported that curcumin, a natural flavonoid from the rhizome of Curcuma longa, attenuated opioid tolerance, although the underlying mechanism remains unclear. In this study, we tested the hypothesis that curcumin may inhibit Ca(2+)/calmodulin-dependent protein kinase II α (CaMKIIα), ...
