Transfection methods are widely used to study miscellaneous aspects of cell biology. The transfection of plasmids encoding tagged proteins, for instance, allows the visualization of the location and behavior of proteins in living cells. With the discovery of RNA interference (RNAi), it is now also possible to specifically prevent the production of certain proteins within a cell via the transfec...
Mutation of the mitochondrial protein tafazzin causes dilated cardiomyopathy in Barth syndrome. We employed an adenovirus as a vector to transfer tafazzin small hairpin RNA (shRNA) into neonatal ventricular myocytes (NVMs) to investigate the effects of tafazzin knockdown. The tafazzin shRNA adenovirus consistently knocked down tafazzin mRNA and lowered cardiolipin while significantly decreasing...
Acute gene inactivation using short hairpin RNA (shRNA, knockdown) in developing brain is a powerful technique to study genetic function; however, discrepancies between knockdown and knockout murine phenotypes have left unanswered questions. For example, doublecortin (Dcx) knockdown but not knockout shows a neocortical neuronal migration phenotype. Here we report that in utero electroporation o...
in this study, several designed creb1-specific shrnas cloned into lentiviral transfer vectors were screened in293t by transient transfection assays. relative creb1 expression was determined by relative qrt-pcr. all of the designed shrnas gave some level of knockdown. one shrna was more effective for knocking down the specific gene among others. the predicted sirnas activities as determined by r...
Because of the lack of pharmacological approaches, molecular genetic methods have been required to differentiate between angiotensin type 1(AT1) receptor subtypes AT1a and AT1b. RNA interference is a new tool for the study of gene function, producing specific downregulation of protein expression. In this study, we used the small hairpin RNA (shRNA) cassette method to screen target sites for sel...
Transient transfection promoter reporter assays are commonly used in the study of transcriptional regulation, and can be used to define and characterize both cis-acting regulatory sequences and trans-acting factors. In the process of using a variety of reporter assays designed to study regulation of the rhodopsin (rho) promoter, we discovered that rhodopsin promoter-driven reporter expression c...
Efficient intracellular Ca²⁺ ([Ca²⁺]i) homeostasis in skeletal muscle requires intact triad junctional complexes comprised of t-tubule invaginations of plasma membrane and terminal cisternae of sarcoplasmic reticulum. Bin1 consists of a specialized BAR domain that is associated with t-tubule development in skeletal muscle and involved in tethering the dihydropyridine receptors (DHPR) to the t-t...
