MicroRNA and Glial Tumors: Tiny Relation with Great Potential

Determination of CD117 Expression in Glial Tumors and Its Comparison between High Grade and Low Grade Tumors

   Background and Objective: Gliomas are the most common primary brain tumors. Despite therapeutic advances, the majority of gliomas do not respond to either chemo or radiotherapy. CD117, the gene product of c-kit has been expressed in cells of glial tumors. Because gastrointestinal stromal tumors (GISTs) that express CD117 respond dramatically to treatment with tyrosine kinase inhibitors, ide...

Estrogen Receptor Expression in Glial Tumors of Iranian Patients: A Single Center Experience

Background & Objective: Gliomas are the most common type of primary intracranial tumors in adults. The expression of estrogen receptors varies in different grades of glial tumors, and some studies have suggested that this expression might have a prognostic value. It seems that estrogen receptor expression negatively correlates with the histological grade of gliomas. In the pres...

Evaluation of Diffusion Anisotropy and Diffusion Shape in Grading of Glial Tumors

Background: The most common primary tumors of brain are gliomas. Grading of tumor is vital for designing proper treatment plans. The gold standard choice to determine the grade of glial tumor is biopsy which is an invasive method.Objective: In this study, we try to investigate the role of fractional anisotropy (diffusion anisotropy) and linear anisotropy ...

MicroRNA and Male Infertility: A Potential for Diagnosis

Role of microRNA as a biomarker in Alzheimer’s disease

Introduction: MicroRNAs are small, non-coding, and protected RNA molecules that regulate gene expression after transcription by mRNA degradation or inhibition of protein synthesis. The function of these molecules is critical to many cellular processes, including growth, development, differentiation, homeostasis, apoptosis, aging, stress resistance. In addition, some diseases including cancer, a...
