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 .
The Task Force guidelines say that all women should start regular mammograms at age 40, but women who are considered high risk may need to start screening even earlier.
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.
Trastuzumab deruxtecan is the first approved therapy by the US Food and Drug Administration (FDA) targeted to people with the HER2-low breast cancer subtype. [4] DNA-based classification. Understanding the specific details of a particular breast cancer may include looking at the cancer cell DNA or RNA by several different laboratory approaches ...
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:
Gene expression profiling is a technique used in molecular biology to query the expression of thousands of genes simultaneously. While almost all cells in an organism contain the entire genome of the organism, only a small subset of those genes is expressed as messenger RNA (mRNA) at any given time, and their relative expression can be evaluated.
