retinoblastoma/carbohydrate

Fifty formalin-fixed and paraffin-embedded retinoblastoma specimens and five normal human eyes were studied with the monoclonal anti-Leu-7 antibody, directed against the HNK-1 carbohydrate epitope that is shared by human natural killer cells and many neuronal, glial and neuroectodermal cells. The

In this work, we focused on mesoporous silica nanoparticles (MSN) for one photon excitated photodynamic therapy (OPE-PDT) combined with drug delivery and carbohydrate targeting applied on retinoblastoma, a rare disease of childhood. We demonstrate that bitherapy (camptothecin delivery and

Various studies which relate to the immunohistochemical identification of neuronal, glial, carbohydrate and nucleic acid associated antigens in retinoblastoma will be reviewed. The majority of these studies appear to support the concept that retinoblastomas arise, in situ, from neuron committed

OBJECTIVE To screen out retinoblastoma (RB)-related serum tumor markers by measuring the levels of serum alpha fetoprotein (AFP), carcino-embryonic antigen (CEA), neuron-specific enolase (NSE), carbohydrate antigen 125 (CA125), carbohydrate antigen 153 (CA153), carbohydrate antigen 199 (CA199), and

Plant lectins have previously been employed to map the composition of cellular glycoconjugates on retinoblastoma and other tumor cells. To characterize the cellular receptors in protein-carbohydrate interactions, we have applied cytological markers (fluorescent neoglycoproteins) containing common

Glycodendrimeric porphyrins seem promising photosensitizers usable in photodynamic therapy. Evidence of their ability to interact with an artificial supported bilayer membrane exhibiting a model sugar receptor has been previously shown. In the present work, the interaction of the glycodendrimeric

The binding of eleven biotin- or peroxidase-coupled lectins with different carbohydrate specificities to tumour tissue and remaining morphologically normal retina was studied in ten formalin-fixed and paraffin-embedded human eyes with retinoblastoma. In undetached retinas, outer and inner segments

OBJECTIVE Fatty acid synthase (FAS) performs the anabolic conversion of dietary carbohydrate or protein to fatty acids. Many common human cancers express high levels of FAS, and its differential expression between normal and neoplastic tissues has led to the consideration of FAS as a target for

Inositol hexaphosphate (IP6) is a naturally occurring polyphosphorylated carbohydrate with demonstrated anti-proliferative and anti-cancer activity in mammary cells. We hypothesized that IP6 modulates cell cycle proteins by action on cytoplasmic signaling molecules. The effects of both

The results of conventional treatments for lung cancer remain poor and long-term survival rates have changed little over the last 10 years. In the same period of time there has been an explosion in the knowledge on the processes of cellular transformation, tumour progression, invasion and

Pigment epithelium-derived factor (PEDF) is a neurotrophic protein and a member of the serine protease inhibitor superfamily. Here we describe the identification of PEDF in bovine eyes and optimization of its purification from this natural source. We have developed a polyclonal antibody to

OBJECTIVE Pancreatic mucinous cystic tumor (MCT(P)) and ovarian mucinous cystic tumor (MCT(O)) show common features. However, there are few studies showing a comparison of both types of tumor. We immunohistochemically studied both types of tumor to clarify their characteristics. METHODS Eight

Extensive research during the past three decades has demonstrated the mechanisms by which an imbalance in the redox status of prooxidant/antioxidant reactions in cells with advantage of prooxidant reactions (oxidative stress, OS) can cause peroxidation of nucleic acids, bases, lipids, proteins and

Cell surface carbohydrates play an important role in several biological, immunological, and neoplastic phenomena including development, growth regulation, cellular locomotion, receptor activation, and tumour metastasis. Fluorescein labelled lectins which bind to specific carbohydrate residues in

BACKGROUND Activation of the renin-angiotensin and sympathetic nervous systems may alter the cardiac energy substrate preference, thereby contributing to the progression of heart failure with normal ejection fraction. We assessed the qualitative and quantitative effects of angiotensin II (Ang II)
