Volume 9, Issue 2 , April 2017, Pages 67-72


  Stevia rebaudiana bertoni is a plant with sweetening properties. This medicinal plant is perennial and from Asteraceae family. Its leaves contain glycoside compounds of a sugar part and non-sugar sectors. One of the glycosides compounds is Rebaudioside‌A which has a greater importance in market. Several ...  Read More

MicroRNA Binding Site Polymorphisms are Associated with the Development of Gastric Cancer

Jamal Asgarpour; Jamshid Mehrzad; Seyyed Abbas Tabatabaei Yazdi

Volume 9, Issue 2 , April 2017, Pages 73-77


  MicroRNAs (miRNAs) binding to the 3'-untranslated regions (3'-UTRs) of messenger RNAs (mRNAs), affect several cellular mechanisms such as translation, differentiation, tumorigenesis, carcinogenesis and apoptosis. The occurrence of genetic polymorphisms in 3'-UTRs of target genes affect the binding affinity ...  Read More
