To achieve lung cancer targeted therapy, folic acid (FA) and transferrin (Tf) modified cisplatin (CDDP) loaded nanoparticles were applied for the in vitro and in vivo evaluation. The aim of this research was to develop FA modified SS bonds based prodrug of CDDP (namely FA-ss-CDDP) and Tf modified cystamine-oleic acid (Tf-ss-OA). Further, FA-ss-CDDP and Tf-ss-OA were used to prepare NPs, which could target the lung tumor cells through receptor-mediated pathways to increase the efficiency of CDDP. FA and Tf modified CDDP loaded NPs (FA/Tf-CDDP-NPs) were constructed...

BACKGROUND AND AIMS: 5T4 is a transmembrane glycoprotein with limited expression in normal adult tissues and expression in some solid tumours. It is unclear whether 5T4 is preferentially expressed by stem or differentiated cell types. Modes of 5T4 regulation are unknown despite its ongoing development as a cancer immunotherapy target. Our aims were to clarify the differentiation status of 5T4 expressing cells in breast cancer and to understand the mechanism underlying 5T4 membrane presentation...

Ruthenium (Ru) complexes are known for their promising anticancer activity presumably due to octahedral coordination geometry, slow ligand exchange rate, the range of different oxidation states and target specificity. This review article summarizes the physicochemical processes which are responsible for the selectivity of Ru complexes toward cancer cells over the normal cells. Emphasis has been given on the activation mechanism of Ru(III) complex administered as a prodrug and then the release of active species in an acidic environment of cancer cell through normal or photo induced hydrolysis or ligand oxidation...

Transferrin is iron (III)-binding protein that transports Fe (III) ion to cells in different parts of the body. At saturation level 70% of transferrin remains free from iron (apo-transferrin), suggesting a broader scope of binding capabilities with non-iron (III) metal ions. Our previous work demonstrated that transferrin can effectively coordinate with noble metal ions. Hence to improve our understanding of the in-vitro metal-interaction behavior of the protein and how it correlates with its functions invivo, the interactions between apo-transferrin and medicinally important noble metals, Au (I), Au (III), Os (III), Pt (IV), Ir (III) and Ru (III) were investigated in the mobility shift mode of affinity capillary electrophoresis...

PURPOSE: Transferrin receptor (TfR) is up-regulated in various malignant tumors not only to meet the iron requirement, but also to increase the cell survival via participation in various cellular signaling pathways. Here we explored transferrin as ligand for Poly(ethylene Glycol) (PEG)-ylated vitamin-E/lipid (PE) core micelles (VPM). METHODS: Transferrin modified polymer was synthesized and drug loaded micelles were evaluated in 2D Hela and HepG2 cancer cells for cellular uptake and cytotoxicity and in 3D Hela spheroids for growth inhibition, uptake and penetration studies...

The effect of chitosan decoration on the transport of epigallocatechin (EGC)-encapsulated ferritin cage across the Caco-2 cells was investigated. After the encapsulation of EGC in apo-red bean (adzuki) ferritin (apoRBF), the EGC-loaded apoRBF nanoparticle (ER) was fabricated with an encapsulation ratio of 11.6% (w/w). The results indicated that different chitosan molecules (with molecular weights of 980, 4600, 46 000, and 210 000 Da) could attach onto the apoRBF via electrostatic interactions to form ER-chitosan complexes (ERCs) (ERCs980 , ERCs4600 , ERCs46000 , and ERCs210000 )...

BACKGROUND: Rapid turnover proteins (RTPs), such as transthyretin (TTR), retinol binding protein (RBP), and transferrin (Tf), provide an accurate assessment of nutritional status but are susceptible to inflammation. Lipid-related markers, which have short half-lives in serum, may be better suited for nutritional assessment. We sought to identify sensitive nutritional markers unaffected by inflammation. METHODS: Fasting serum samples were collected from 30 malnourished inpatients and 25 healthy volunteers...

In vast areas of the ocean, the scarcity of iron controls the growth and productivity of phytoplankton. Although most dissolved iron in the marine environment is complexed with organic molecules, picomolar amounts of labile inorganic iron species (labile iron) are maintained within the euphotic zone and serve as an important source of iron for eukaryotic phytoplankton and particularly for diatoms. Genome-enabled studies of labile iron utilization by diatoms have previously revealed novel iron-responsive transcripts, including the ferric iron-concentrating protein ISIP2A, but the mechanism behind the acquisition of picomolar labile iron remains unknown...

OBJECTIVE: Iron deficiency is the most common nutrient deficiency in the world. While deficiency can often be resolved through dietary supplementation with iron, adverse events are common and frequently preclude compliance. The objective of this study was to determine whether a food-derived dietary supplement containing a low dose of iron and nutrients that increase iron absorption could resolve iron deficiency with fewer adverse events than reported at higher doses. METHODS: A pilot clinical trial (NCT02683369) was conducted among premenopausal women with nonanemic iron deficiency that was verified by blood screening...

Excitoneurotoxicity is regarded as one of the mechanisms of the death of retinal ganglion cells induced by retinal central artery occlusion and glaucoma. Oxidative stress is at least in part involved in excitoneurotoxicity. Fenton reaction, which is catalyzed by Fe2+ , is known to cause formation of hydroxyl radical, one of reactive oxygen species, suggesting that chelation of iron may be protective against excitoneurotoxicity. In the present study, we histologically evaluated whether zinc-deferoxamine (Zn-DFO) and deferasirox (DFX), common iron-chelating agents, were protective against N-methyl-D-aspartate (NMDA)-induced retinal injury in the rat in vivo...

The transplantation of insulin-producing cells (IPCs) or pancreatic progenitor cells is a theoretical therapy for diabetes with insulin insufficiency. Isolated hepatocytes from newborn rats (within 24 h after birth) were progressively induced into IPCs using 5-aza-2'-deoxycytidine, Trichostatin A, retinoic acid, insulin-transferrin-selenium, and nicotinamide. We transplanted Pdx1+ pancreatic progenitors into STZ-induced diabetic mice and found the decreased blood glucose and increased insulin level in comparison with diabetic model...
