The channel capacity and information density of biochemical signaling cascades
Living cell signaling systems include multistep biochemical signaling reaction cascades (BSCs) comprising modifications of molecular signaling proteins. Substantial data on BSCs have been accumulated in the field of molecular biology and the analysis of signaling systems requires qualitative evaluation. However, quantification of the information and channel capacity of BSCs has not been focused...
متن کاملBiochemical changes during carcinogenesis by plastic films.
The fac t t ha t sarcomas are induced in rodents by imbedded films of polymers has been established in this l abora to ry (1~-15) and had been conf irmed by a number of o ther invest igators (~, 6, 8, 10, 19). Subsequent studies have shown t h a t this phenomenon is not l imited to films of organic polymers b u t t h a t imbedded meta l foils have the same effect (9, 10, l l ) . This fact , in ...
متن کاملSpecific Immunological & Biochemical Markers in Oral Carcinogenesis
Worldwide, oral carcinoma is one of the most prevalent cancers and is one of the 10 most common causes of death. If oral cancers and cancers of nasopharynx, pharynx, larynx, sinus and salivary glands are combined, these sites represent more than 5% of total body cancers. Approximately 95% of oral squamous cell carcinoma (OSCC) occurs in people older than 40 years. However OSCC at a young age ha...
متن کاملQuantifying efficient information transduction of biochemical signaling cascades
Cells can be considered as systems that utilize changes in thermodynamic entropy as information. Therefore, they serve as useful models for investigating the relationships between entropy production and information transmission, i.e., signal transduction. Based on the hypothesis that cells apply a chemical reaction cascade for the most efficient transduction of information, we adopted a coding ...
متن کاملVanadium, a versatile biochemical effector in chemical rat mammary carcinogenesis.
Recent studies indicate the role of the micronutrient vanadium in chemoprevention in many animal models, human cancer cell lines, and also in xenografted human carcinomas of the lung, breast, and gastrointestinal tract. The present studies were undertaken to ascertain the antineoplastic potential of vanadium in a defined model of mammary carcinogenesis. Female Sprague-Dawley rats, at 50 days of...
