lysolecithin/neoplasms

Physiological characters of Ehrlich ascites tumor cell membranes were altered by papaverine. The agent induced changes in membrane potential as monitored by cyanine dye (diS-C3-(5)) technique. Papaverine also strongly inhibited increase in membrane permeability to K+ ion induced by lysolecithin. In

Previous data have demonstrated that doxorubicin (DOX) released from a lysolecithin-containing thermosensitive liposome (LTSL) can shut down blood flow in a human tumor xenograft (FaDu) in mice when the treatment is combined with hyperthermia (HT), suggesting that LTSL-DOX is a potential

OBJECTIVE In previous reports, laboratory-made lysolecithin-containing thermosensitive liposome encapsulating doxorubicin (LTSL-DOX) showed potent anticancer effects in FaDu human squamous cell carcinoma. To further study the spectrum of LTSL-DOX activity, the efficacy of its commercial formulation

The utilization of acetate is fundamental to numerous cellular processes. At the level of chromatin, histone acetylation is thought to regulate transcription, and acetate is a major source of cellular energy as it is the substrate for the citric acid cycle. The present work investigates the

The obstacle to successful remyelination in demyelinating diseases, such as multiple sclerosis, mainly lies in the inability of oligodendrocyte precursor cells (OPCs) to differentiate, since OPCs and oligodendrocyte-lineage cells that are unable to fully differentiate are found in the areas of

Proteoglycans are promising therapeutic targets in Multiple Sclerosis (MS), because they regulate many aspects of the immune response. This was studied using surfen, an agent that binds both heparan sulphate proteoglycans (HSPGs) and chondroitin sulphate proteoglycans (CSPGs). Initial cell culture

An 9.4-kDa antifungal peptide designated as campesin was isolated from seeds of the cabbage Brassica campestris. The isolation procedure involved affinity chromatography on Affi-gel blue gel, ion exchange chromatography on Q-Sepharose and Mono S, and gel filtration on Superdex 75 and Superdex

Interdisciplinary cooperation between basic and clinical research has resulted in the discovery and development of alkylphosphocholines, a new class of substances for the treatment of breast cancer. In contrast to most antitumor substances, the alkylphosphocholines do not attack the cell nucleus,

Levodopa and dopamine are naturally occurring catecholamines with antitumor activity in several experimental tumor systems. Previous studies suggested that their cytotoxic effect was related in part to their inhibitory effect upon DNA polymerase. We have examined the effects of levodopa, dopamine,

Hypotheses are presented of the detailed molecular structure of two prostaglandin receptors both concerned in tumor-promotion processes. These structures have been derived by the comparison of the molecular structure of agents active at the site with (i) a simple theoretical protein structure and
