The Antidepressant Mechanism of JiaWeiWenDan Decoction Regulating p38MAPK-ERK5 Signal Transduction Pathway

The mechanism of hedgehog signal transduction.

Hedgehog (Hh) proteins are one of a small number of families of secreted signalling proteins that are responsible for cell interactions during development in many animals. As such, Hh signals produce many different responses at different times and in different cells. As for other multifunctional ligands, this requires regulated patterns of expression, special mechanisms for ligand movement betw...

The mechanism of IL-5 signal transduction.

Cytokines are important regulators of hematopoiesis. They exert their actions by binding to specific receptors on the cell surface. Interleukin-5 (IL-5) is a critical cytokine that regulates the growth, activation, and survival of eosinophils. Because eosinophils play a seminal role in the pathogenesis of asthma and allergic diseases, an understanding of the signal transduction mechanism of IL-...

Signal transduction pathways regulating hematopoietic differentiation.

Signal transduction systems regulating fruit ripening.

Fruit ripening is a unique aspect of plant development with direct implications for a large component of the food supply and related areas of human health and nutrition. Recent advances in ripening research have given insights into the molecular basis of conserved developmental signals coordinating the ripening process and suggest that sequences related to floral development genes might be logi...

The ethylene signal transduction pathway in plants.

Ethylene (C2H4), the chemically simplest plant hormone, is among the best-characterized plant growth regulators. It participates in a variety of stress responses and developmental processes. Genetic studies in Arabidopsis have defined a number of genes in the ethylene signal transduction pathway. Isolation of two of these genes has revealed that plants sense this gas through a combination of pr...
