Cross-talk of GPCRs and RTKs and its effects on oncotherapy / 中国药理学通报

G protein-coupled receptors (GPCRs) are the largest cell surface receptor family, which mediates activities of almost all known cellular response to ligands, including hormones release, neurotransmitters and sensory input.GPCRs can promote development and progression of gastric cancer, colorectal cancer, lung cancer and breast cancer and other tumors.Tyrosine kinase receptors (RTKs) are another important family of membrane receptors, which can regulate cell proliferation, differentiation, migration and survival.Overexpression of RTKs has been found in many cancer cells.Therefore, GPCRs and RTKs are equally important in the clinical treatment of cancer therapeutic.However, GPCRs and RTKs are not independent, and they can use common signal transduction.The present study show that crosstalk between GPCRs and RTKs can facilitate migration of lung epithelial cells, increasing survival of nerve cells and promoting tumor occurrence and development.This article mainly focuses on crosstalk between GPCRs and RTKs and their roles in tumorigenesis and oncotherapy.

The Role of JNK kinase in apoptosis and its relationship with cancer / 中国药理学通报

JNK is a key protein in the third stages of MAPK pro-tein kinase activation cascade,and is located in the key node of multiple signal transduction network.It plays a pivotal role in the cell proliferation,differentiation,apoptosis and some other important cell biological processes.Therefore it acts as an im-portant factor in regulating the development of some major human diseases,such as cancer.But the functional diversity and com-plexity of three JNK isoforms in different cell types make it diffi- cult to develop anticancer drugs with JNK as a treatment target. In this review,we summarized the apoptotic signaling network of JNK and the regulation functions of JNK in cell apoptosis and proliferation.We also discuss the different functions of 3 JNK isoforms in human cancer.

Research progress of TRAIL network against tumor under the guidance of systems biology / 基础医学与临床

Tumor is a system-biology illness.Treatment of this intractable disease by any single medicine has not been realistic.In this review, we analyze the anti-tumor network of Tumor Necrosis Factor-related Apoptosis-indu-cing Ligand ( TRAIL ) by a system-biology technology and try to providecin individualized treatment strategy for TRAIL based therapy .

Clinical application of event related potential P300 / 中国组织工程研究

Event related potential generated and developed in 1990's,which provides an objective and feasible approach to describe mental activities and evaluate cognitive function.It has become a study focus of mentalics,neurology,gerontology and psychology.Event related potential plays an important role in clinically evaluating and identifying various cognitive disorders.This paper summarized clinical application of event related potential P300.
