The G-quadruplex decoy strategy is another promising approach for targeting cancer cells by exploiting the unique structural features of the G-quadruplex. The strategy involves designing synthetic oligonucleotides that mimic the G-quadruplex structure and compete with the endogenous G-quadruplexes for binding to transcription factors.
Multi-stranded DNA microarrays (triplex-DNA microarrays and quadruplex-DNA microarrays) Multi-stranded DNA and RNA microarrays can be used to identify novel drugs that bind to these multi-stranded nucleic acid sequences. This approach can be used to discover new drugs and biologicals that have the ability to inhibit gene expression.
The term intrinsic DNA fluorescence refers to the fluorescence emitted directly by DNA when it absorbs ultraviolet (UV) radiation. It contrasts to that stemming from fluorescent labels that are either simply bound to DNA or covalently attached to it, [1] [2] widely used in biological applications; such labels may be chemically modified, not naturally occurring, nucleobases.
This method could potentially modulate the activity of G-quadruplex DNA, crucial in gene expression and telomere maintenance, offering new therapeutic avenues, particularly in cancer treatment. The study underscores photopharmacology's promise in targeting specific DNA structures, suggesting G-quadruplex DNA as a viable target for future ...
Real time PCR uses fluorophores in order to detect levels of gene expression.. Cells in all organisms regulate gene expression by turnover of gene transcripts (single stranded RNA): The amount of an expressed gene in a cell can be measured by the number of copies of an RNA transcript of that gene present in a sample.
Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression, or through biochemical analysis to measure specific protein output.

Nature Reviews Cancer is a monthly review journal covering the field of oncology. It was established in 2001. [1] The editor-in-chief is Anna Dart. [2] Abstracting ...
Because of inherent limits in the DNA repair mechanisms, if humans lived long enough, they would all eventually develop cancer. [87] [88] DNA damages that are naturally occurring, due to normal cellular processes that produce reactive oxygen species, the hydrolytic activities of cellular water, etc., also occur frequently. Although most of ...
