Numerous experimental and clinical studies indicate that chronic inflammation is closely related to the initiation, progression, and spread of cancer, in which proinflammatory cytokines, such as interleukin (IL)-6, IL-1β, and tumor necrosis factor-α (TNF-α), and transcription factors, such as nuclear factor-κB (NF-κB), and signal transducer and activator of transcription 3 (STAT3), play pivotal roles. Stimulated by proinflammatory cytokines, NF-κB and STAT3 can modulate the expression of target genes, most of which are oncogenic ones, and promote the survival, proliferation, invasion, and metastasis of cancer cells...

Curcumin is a natural polyphenolic compound, widely acclaimed for its antioxidant, anti-inflammatory, antibacterial and anti-cancerous properties. However, its use has been limited due to low-aqueous solubility and poor bioavailability, rapid clearance and low cellular uptake. In order to assess the effect of glycosylation on pharmacological properties of curcumin, the one-pot multi-enzyme (OPME) chemoenzymatic glycosylation reactions with UDP-α-D-glucose or UDP-α-D-2-deoxyglucose as donor substrate were employed...

Tetronic(®) 1307 (here after written as T1307) is a hydrophilic ethylene oxide-propylene oxide (EO-PO) star block copolymer with long EO chains (Total MW- 18000 and 70% EO). Although biocompatible, its use as a nanocarrier is restricted owing to its high critical micelle concentration (CMC) and temperature (CMT). We examined if the addition of glucose, a common pharmaceutical ingredient promotes micellization. Scattering and thermal studies show formation of stable unimodal micelles and cloud point (CP) decreased linearly...

Curcumin, a natural polyphenol, exhibits anti-oxidant, anti-inflammatory, anti-neoplastic and chemopreventive properties. In fact, targeting of this natural anticancer agent has received a great deal of attention during the recent years. In this study, we proposed that curcumin conjugation with lactoferrin molecules may lead to a potential drug delivery system targeted toward cancerous cells through both active and passive targeting. In this regard, curcumin conjugated lactoferrin was developed via a carbodiimide-based coupling reaction and the resulting conjugates were appraised for their molecular properties as a potential targeted drug delivery system...

Photodynamic therapy is widely used in the clinical treatment of tumors, especially skin cancers. It has been reported that the photosensitizer curcumin, in combination with ultraviolet radiation B, induces HaCaT cell apoptosis, and this effect may be due to the activation of caspase pathways. In this study, we examined the photodynamic effects of demethoxycurcumin, a more stable analogue of curcumin, to determine whether it could induce apoptosis in skin cancer cells. We investigated the effects of a combination of ultraviolet radiation B and demethoxycurcumin on apoptotic cell death in A431 and HaCaT cells and determined the molecular mechanism of action...

Most chemotherapeutic drugs commonly suffer from several shortcomings, including the lack of aqueous solubility, limited stability and adverse side effects. Although caging strategy has recently been employed as an effective approach to conceal and stabilize these drugs to achieve light-activated cancer therapy, it is plagued by the sophisticated drug modification process and deleterious solvent usage. In addition, using UV or Visible light to remove photocaged group is restricted to its limited tissue penetration ability in and phototoxicity...

Effective chemoprevention is critical for improving outcomes of oral cancer. As single agents, curcumin and metformin, are reported to exhibit chemopreventive properties, in vitro as well as in patients with oral cancer. In this study, the chemopreventive efficacy of this drug combination was tested in a 4NQO (4-nitro-quinoline-oxide) induced, mice oral carcinogenesis model. Molecular analysis revealed a cancer stem cell (CSC)-driven, oral carcinogenic progression in this model, wherein a progressive increase in the expression of CSC-specific markers (CD44 and CD133) was observed from 8th to 25th week, at transcript (40 to 100 fold) and protein levels (p≤0...

Curcumin is known as a natural dietary polyphenol which is extracted from Curcuma longa L. It has been shown that curcumin has a variety of pharmacological effects such as antioxidant, anti-cancer, anti-inflammatory, and anti-microbial activities. Anti-cancer effects of curcumin are due to targeting of a wide range of cellular and molecular pathways involved in cancer pathogenesis including NF-kB, MAPK, PTEN, P53, and microRNAs (miRNA) network. Multiple lines of evidence have indicated that curcumin exerts its therapeutic effects via regulating miRNA expression (e...

Natural products or nutraceuticals have been shown to elicit anti-aging, anti-cancer and other health-enhancing effects. A key target of the effects of natural products may be the regulation of microRNA (miR) expression which results in cell death or prevents aging, diabetes, cardiovascular and other diseases. This review will focus on a few natural products, especially on resveratrol (RES), curcumin (CUR) and berberine (BBR). RES is obtained from the skins of grapes and other fruits and berries. RES may extend human lifespan by activating the sirtuins and SIRT1 molecules...

Objective: Curcumin is known for its anti-oxidative, anti-inflammatory and anti-tumorigenic qualities at concentrations ranging from 3.7µg/ml to 55µg/ml. Therefore it is pre-destined for tumour therapy. Due to high oral doses that have to be administered and the low bioavailability of curcumin new therapy concepts have to be developed. One of these therapy concepts is the combination of low curcumin concentrations and UVA or visible light. Aim of our study was to investigate the influence of this treatment regime on oral squamous cell carcinoma cells...

BACKGROUND: Curcumin has proven to be a potent antitumor agent in both preclinical and clinical models of colorectal cancer (CRC). It has also been identified as a ligand of the transcription factor known as the aryl hydrocarbon receptor (AHR). Our laboratory has identified the AHR as a mechanism which contributes to both tumorigenesis in a mouse model of inflammatory CRC as well an apoptotic target in vitro. Curcumin's role as an AHR ligand may modulate its effects to induce colon cancer cell death, and this role may be enhanced via structural modification of the curcumin backbone...
