Furthermore, at tissue and organ level, Rap controls the establishment of neural polarity, synaptic growth, synaptic plasticity, neuronal migration and so on. Rap belongs to Ras family which contains two subtypes, Rap1 and Rap2. By binding GTP or GDP Rap transform between active or inactive state, and plays an important role as a molecular switch. Moreover, in the signal pathway of tumor, Rap inhibits cell transformation induced by the oncogene Ras, therefore inhibits the proliferation, invasion and migration of certain cancer cells by interacting with its downstream target molecules. In this review, we summarized the biological functions of Rap and discussed It's significance in cancer therapy and drug treatment of neurological diseases.</p>","PeriodicalId":58541,"journal":{"name":"生理科学进展","volume":"47 1","pages":"14-20"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34675188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the genetic profiles of most human diseases could not be fully explained with the canonical laws of genetics. Paramutation is one of non-Mendelian inheritance phenomenon, which was found in maize first in 1950s. The absence of alteration in nucleotide sequences in the gene-coding alleles suggested that paramutations might involve epigenetic mechanisms to transmit heritable changes in gene expression and determination of phenotypes. Recently, a novel epigenetic mechanism has been found in paramutation researches, emphasized the importance of DNA methyltransferase II mediated RNA (primarily non-coding RNAs) methylation in the occurrence and maintenance of paramutations. Researches on paramutations and their epigenetic mechnisms will not only expand our understanding in the genetic principles of life, but also help to develop new ideas for bioengineer and disease treatments. The present article reviewed the research highlights on molecular mechanisms of paramutation and discussed the prospects in disease study and therapy.</p>","PeriodicalId":58541,"journal":{"name":"生理科学进展","volume":"47 1","pages":"7-13"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34675187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
