Lung squamous cell carcinoma (LSCC) is a common histological lung cancer subtype, but unlike lung adenocarcinoma, limited therapeutic options are available for treatment. Curcumin, a natural compound, may have anticancer effects in various cancer cells, but how it may be used to treat LSCC has not been well studied. Here, we applied curcumin to a human NCI-H292 LSCC cell line to test anticancer effects and explored underlying potential mechanisms of action. Curcumin treatment inhibited NCI-H292 cell growth and increased FOXA2 expression in a time-dependent manner...

Our earlier studies reported a unique potentiated combination (TriCurin) of curcumin (C) with two other polyphenols. The TriCurin-associated C displays an IC50 in the low micromolar range for cultured HPV+ TC-1 cells. In contrast, because of rapid degradation in vivo, the TriCurin-associated C reaches only low nano-molar concentrations in the plasma, which are sub-lethal to tumor cells. Yet, injected TriCurin causes a dramatic suppression of tumors in TC-1 cell-implanted mice (TC-1 mice) and xenografts of Head and Neck Squamous Cell Carcinoma (HNSCC) cells in nude/nude mice...

Curcumin (Cur) has potent antitumor activity; however, its clinical use is limited due to its hydrophobicity and instability at physiological pH. In this work, Cur was incorporated into MPEG2K-P(CL-co-LLA) micelles to form the Cur-loaded micelles with drug loadings from 4.72% to 35.21% depending on the ratios of drug to MPEG2K-P(CL-co-LLA). The resulting Cur-loaded micelles were spherical with mean hydrodynamic diameters in the range of 28.8 to 58.6 nm, having excellent water-solubility and good stability at pH 7...

BACKGROUND: The process of optimization and fabrication of nanoparticle synthesis for preclinical studies can be challenging and time consuming. Traditional small scale laboratory synthesis techniques suffer from batch to batch variability. Additionally, the parameters used in the original formulation must be re-optimized due to differences in fabrication techniques for clinical production. Several low flow microfluidic synthesis processes have been reported in recent years for developing nanoparticles that are a hybrid between polymeric nanoparticles and liposomes...

Worldwide, hepatocellular carcinoma (HCC) is the major subtype of primary liver cancers. HCC is typically diagnosed late in its course. With respect to cancer, the genomic actions of vitamin D are mediated through binding to the Vitamin D Receptor (VDR), which allows it to modulate the expression of genes in a cell-and tissue-specific manner. Epigenetics is a rapidly evolving field of genetic study applicable to HCC. Changes in DNA methylation patterns are thought to be early events in hepatocarcinogenesis...

Curcumin is a naturally occurring polyphenol isolated from Curcuma longa that has various pharmacological activities, including, anti-inflammatory, anti-oxidant and anti-cancer properties. The anticancer effect of curcumin is attributed to activation of apoptotic pathways in cancer cells, as well as inhibition of inflammation and angiogenesis in the tumour microenvironment and suppression of tumour metastasis. Angiogenesis, which is the formation of new blood vessels from pre-existing ones, is a fundamental step in tumour growth and expansion...

Curcumin (cur) has been comprehensively studied for its various biological properties, more precisely for its antitumor potential and it has shown the promising results as well. On the other hand, Chlorin e6 (Ce6) has mostly been used as a photosensitizer in photodynamic therapy (PDT) against a variety of carcinomas. In the present study, we have synthesized a series of Chlorin e6-curcumin (Ce6-cur) conjugates and investigated their photosensitizing potential against pancreatic cancer cell lines. All the synthesized compounds were characterized by UV, 1H NMR, 13C NMR and LC-MS...

Curcumin has anti-inflammatory, anti-oxidant and anti-proliferative properties established largely by in vitro studies. Accordingly, oral administration of curcumin beneficially modulates many diseases including diabetes, fatty-liver disease, atherosclerosis, arthritis, cancer and neurological disorders such as depression, Alzheimer's or Parkinson's disease. However, limited bioavailability and inability to detect curcumin in circulation or target tissues has hindered the validation of a causal role. We established curcumin-mediated decrease in the release of gut bacteria-derived lipopolysaccharide (LPS) into circulation by maintaining the integrity of the intestinal barrier function as the mechanism underlying the attenuation of metabolic diseases (diabetes, atherosclerosis, kidney disease) by curcumin supplementation precluding the need for curcumin absorption...

Nanoparticles formed by the assembly of protein and polysaccharides are of great interest for the delivery of hydrophobic molecules. Herein, the formation of genipin-crosslinked nanoparticles from caseinate (CS) and chitosan (CH) is reported for the delivery of curcumin, a polyphenolic compound from turmeric, to cells. Genipin-crosslinked CS-CH nanoparticles (G-CCNPs) having a diameter of ∼250 nm and a low polydispersity index showed excellent stability over a wide pH range, as indicated by dynamic light scattering and transmission electron microscopic measurements...

The spice turmeric (Curcuma longa L.) has a long history of use as an anti-inflammatory agent. The active component curcumin induces a variety of diverse biological effects and forms a series of degradation and metabolic products in vivo. Our hypothesis is that the field of toxicogenomics provides tools that can be used to characterize the mode of action and toxicity of turmeric components and to predict turmeric-drug interactions. Male Sprague-Dawley rats were treated for 4 days with turmeric root containing about 3% curcumin (comparable to what people consume in the fresh or dried root) or a fraction of turmeric enriched for curcumin (∼74%) and liver tissue collected for gene expression analysis...

Lung cancer is the major cause of cancer-related death worldwide. Curcumin attracted attention due to its promising anti-cancer properties, however its poor aqueous solubility and bioavailability have to be overcome. In the current study curcumin is encapsulated in krill lipids-based liposomes (marinosomes) to develop a potential anticancer therapy from low-cost and readily available nutraceuticals. Reflux followed by thin drug-lipid film method is used successfully to incorporate the drug into the liposomal membrane at high encapsulation efficiency (EE)...

PURPOSE: The retina is continually exposed to free radicals from its rich blood supply, numerous mitochondria, and photons of light which strike its surface. Most pathological processes that take place in the retina, such as inflammation, cell apoptosis, or angiogenesis, can hence involve free radicals directly or indirectly.  Since inflammatory and oxidative stress pathways underlie retinal pathology, compounds that address these factors are therefore natural choices for treatment. This review article summarizes and provides commentary on curcumin's therapeutic potential use in ophthalmology with principal focus on retinal dosorders...
