Abstract

The relative importance of molecular biology in clinical practice is often underestimated. However, numerous procedures in clinical diagnosis and new therapeutic drugs have resulted from basic molecular research. Furthermore, understanding of the physiological and physiopathological mechanisms underlying several human diseases has been improved by the results of basic molecular research. For example, cloning of the gene encoding leptin has provided spectacular insights into the understanding of the mechanisms involved in the control of food intake and body weight maintenance in man. In cystic fibrosis, the cloning and identification of several mutations in the gene encoding the chloride channel transmembrane regulator (CFTR) have resolved several important issues in clinical practice: cystic fibrosis constitutes a molecular defect of a single gene. There is a strong correlation between the clinical manifestations or the severity of the disease (phenotype) with the type of mutations present in the CFTR gene (genotype). More recently, identification of mutations in the gene encoding a subunit of the renal sodium channel in the Liddle syndrome has provided important insight into the physiopathological understanding of mechanisms i...Continue Reading

CREs: Gene & Cell Therapy

Gene and cell therapy advances have shown promising outcomes for several diseases. The role of cis-regulatory elements (CREs) is crucial in the design of gene therapy vectors. Here is the latest research on CREs in gene and cell therapy.
