    Topics: Medicine
    Notes: Abstract Lens sorbitol dehydrogenase activity was assayed in patients with congenital cataracts, senile cataracts, without cataracts and in one fetal lens. In patients with congenital cataracts we did not observe any abnormality of galactose and sorbitol metabolising enzymes in erythrocytes. In one of these patients with inexplicable congenital cataracts lens sorbitol dehydrogenase deficiency was found. Conclusion Determination of galactose metabolising enzymes, sorbitol dehydrogenase and polyols in lenses may help in understanding the mechanism of formation of inexplicable congenital cataracts.

    Notes: Abstract Nucleic acid molecules with high affinities for a target transcription factor can be introduced into cells as decoy cis-elements to bind these factors and alter gene expression. This review discusses a synthetic single-stranded palindromic oligonucleotide, which self-hybridizes to form a duplex/hairpin and competes with cAMP response element (CRE) enhancers for binding transcription factors. This oligonucleotide inhibits CRE- and Ap-1-directed gene transcription and promotes growth inhibition in vitro and in vivo in a broad spectrum of cancer cells, without adversely affecting normal cell growth. Evidence presented here suggests that the CRE-decoy oligonucleotide can provide a powerful new means of combating cancers, viral diseases, and other pathological conditions by regulating the expression of cAMP-responsive genes.
