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.
The objective of cancer screening is to detect cancer before symptoms appear, involving various methods such as blood tests, urine tests, DNA tests, and medical imaging. [ 1 ] [ 2 ] The purpose of screening is early cancer detection, to make the cancer easier to treat and extending life expectancy. [ 3 ]
Cervical cancer screening is a medical screening test designed to identify risk of cervical cancer. Cervical screening may involve looking for viral DNA, and/or to identify abnormal, potentially precancerous cells within the cervix as well as cells that have progressed to early stages of cervical cancer .
An influential task force just updated guidance on breast cancer screenings for at-risk women. They recommended every-other-year mammograms starting at age 40, a decade earlier than previous guidance.
The different types of topologies in G-quadruplex, propeller, lateral, and diagonal. G-quadruplexes, also known as G4 DNA are secondary structures found in nucleic acids that are rich in guanine. [1] These structures are normally located at the telomeres (the ends of the chromosomes). The G-quadruplex can either be parallel or antiparallel ...
In 1997, the National Cancer Institute published a set of recommendations called the Bethesda guidelines for the identification of individuals who should receive genetic testing for Lynch syndrome related tumors. [6] The NCI revisited and revised these criteria in 2004. [7] The Revised Bethesda Guidelines are as follows:
A genetic screen or mutagenesis screen is an experimental technique used to identify and select individuals who possess a phenotype of interest in a mutagenized population. [1] Hence a genetic screen is a type of phenotypic screen.
The American Academy of Pediatrics (AAP) and the American College of Medical Genetics (ACMG) have provided new guidelines for the ethical issue of pediatric genetic testing and screening of children in the United States. [73] [74] Their guidelines state that performing pediatric genetic testing should be in the best interest of the child. AAP ...
