Quantum dot (Qdot) biosensors have consistently provided valuable information to researchers about cellular activity due to their unique fluorescent properties. Many of the most popularly used Qdots contain cadmium, posing the risk of toxicity that could negate their attractive optical properties.

The structural properties of calcyclin protein are quite well characterized but its function remains obscure. To help elucidate the biological role of calcyclin we have performed the in vitro studies of the Ca(2+)-dependent interaction of Ehrlich ascites tumor cells calcyclin and its cyanogen

In medium containing low concentrations of serum, rat 13762NF mammary adenocarcinoma cell lines and clones (MTPa and MTC; isolated from the locally growing tumor) of low metastatic potential to lung did not exhibit a growth response to lung-conditioned medium, whereas a highly metastatic cell clone

We have described a drug-responsive form of a cell surface NADH oxidase (hydroquinone oxidase) of cancer cells (tNOX) that exhibits unusual characteristics including resistance to proteases, resistance to cyanogen bromide digestion, and an ability to form amyloid filaments closely resembling those

Overproduction of hypochlorous acid (HOCl) has been associated with the development of a variety of disorders such as inflammation, heart disease, pulmonary fibrosis, and cancer through its ability to modify various biomolecules. HOCl is a potent oxidant generated by the myeloperoxidase-hydrogen

Immunoglobulins were isolated by affinity chromatography from sera of two patients with melanoma, one with sarcoma, and one with carcinoma. The affinity columns were prepared by covalently linking the membrane-rich fraction of biopsied melanoma cells to cyanogen bromide-activated agarose beads. The

Green tea and tea catechins, especially (-)-epigallocatechin gallate (EGCG), have been shown to have various health benefits including anti-cancer, anti-metastasis, and anti-cardiovascular disease effects. Our previous studies demonstrated that three plasma proteins, fibronectin, histidine-rich

The imaging of tumor cells and tumor tissue samples is very important for cancer detection and therapy. We have taken advantages of fluorescent silica nanoparticles (FSiNPs) coupled with a molecular recognition element that allows for effective in vitro and ex vivo imaging of tumor cells and

The effects of the monoclonal antibody-mitomycin C conjugate against human colon cancers were studied, in vitro and in vivo. Mitomycin C (MMC) was conjugated with the human colon cancer-specific monoclonal antibody, using a cyanogen bromide method. The effect of the conjugate and free MMC, in vitro,

The collagen content in human pancreatic cancer tissue, tissue of tumor-associated chronic pancreatitis (TACP), and normal pancreatic tissue was determined in 14 patients with pancreatic cancer by measuring the amount of 4-hydroxyproline. Four patients with alcoholic chronic pancreatitis (AlCP) were

BACKGROUND Epigallocatechin-3-gallate (EGCG), one of the major catechins in green tea, is a potential chemopreventive agent for various cancers. The aim of this study was to examine the effect of EGCG on the expression of heat shock proteins (HSPs) and tumor suppression. METHODS Cell colony

The root of Oplopanax elatus (Nakai) Nakai has a well-known history of use for the treatment of diseases such as neurasthenia, cardiovascular disorders, and cancer by the native people in northeast China. It is important to screen and identify the bioactive molecules from its root rapidly. Hereby,

Type IV collagen from the EHS sarcoma, a basement membrane producing tumor, was characterized. Acid extracts of tumor grown in lathyritic animals contain proteins with two predominant collagen chains of apparent molecular weights of 160,000 and 140,000 daltons, designated alpha 1(IV) and alpha

Radiosequence analysis of peptide fragments of the estrogen receptor (ER) from MCF-7 human breast cancer cells has been used to identify cysteine 530 as the site of covalent attachment of an estrogenic affinity label, ketononestrol aziridine (KNA), and an antiestrogenic affinity label, tamoxifen

During conventional procedures for the extraction of collagen from rat fibrosarcoma it was observed that a significant fraction of the acid-soluble collagen remained insoluble when subsequently fractionated at neutral pH. Analysis of this collagenous component, using amino acid analysis, cyanogen
