IGF-I Antisense and Triple-Helix Gene Therapy of Glioblastoma

Presence of MHC-I in rat glioma cells expressing antisense IGF-I-receptor RNA.

The supposed immunogenic character of glioma cells transfected with antisense IGF-I-Receptor (IGF-I-R) expression vector was tested for the presence of MHC-I currently present in cells of IGF-I antisense type. C6 rat glioma cell line was comparatively transfected in vitro with IGF I antisense (pMT-Anti-IGF I) or IGF I Receptor antisense (pMT-Anti-IGF I R) expression vectors. The wild and transf...

Cosuppression of I transposon activity in Drosophila by I-containing sense and antisense transgenes.

We have previously shown that the activity of functional I elements introduced into Drosophila devoid of such elements can be repressed by transgenes containing an internal nontranslatable part of the I element itself and that this repressing effect presents features characteristic of homology-dependent gene silencing or cosuppression. Here we show that transgenes containing a fragment of the I...

Detection of a novel sense-antisense RNA-hybrid structure by RACE experiments on endogenous troponin I antisense RNA.

Conformational changes in the troponin/tropomyosin complex significantly alter the mechanical properties of cardiac muscle. Phosphorylation of cardiac troponin I, part of the troponin/tropomyosin complex, reduces calcium affinity, which leads to increased relaxation of cardiac muscle. Because cardiac troponin I plays a central role in tuning the heart to different work demands, detailed knowled...

Antisense Technology and its Implications Gene Expression Antisense Technology The Design and Targeting of Antisense ODNs

While many studies have examined the numerous physiological and pharmacological factors which can induce the expression of c-fos and other immediate-early genes, few have examined the consequences of altering their expression pattern. Using antisense oligonucleotides to c-fos, we demonstrate that amphetamine-induced c-fos expression c m be attenuated in vivo, in specific brain regions. This uni...
