Prognostic markers are biomarkers used to measure the progress of a disease in the patient sample. [1] Prognostic markers are useful to stratify the patients into groups, guiding towards precise medicine discovery. The widely used prognostic markers in cancers include stage, size, grade, node and metastasis. In addition to these common markers ...
Researchers have identified a new biomarker for Alzheimer's disease, which could help doctors diagnose it before symptoms start showing.
Levels of CD4 and CD8 memory T cells and naive T cells have been used to give good predictions of the expected lifespan of middle-aged mice. [5] Advances in big data analysis allowed for the new types of "aging clocks" to be developed. The epigenetic clock is a promising biomarker of aging and can accurately predict human chronological age. [6]
Biomarker discovery is a medical term describing the process by which biomarkers are discovered. Many commonly used blood tests in medicine are biomarkers. There is interest in biomarker discovery on the part of the pharmaceutical industry; blood-test or other biomarkers could serve as intermediate markers of disease in clinical trials, and as possible drug targets.
In this application, biomarkers act as stand-ins for the effects of a drug on cancer progression and survival. Ideally, the use of validated biomarkers would prevent patients from having to undergo tumor biopsies and lengthy clinical trials to determine if a new drug worked. In the current standard of care, the metric for determining a drug's ...
In December 2023, Nature Computational Science published a paper introducing the life2vec algorithm, [1] developed as part of a scientific research project. [2] [3] Life2vec is a transformer-based model, similar to those used in natural language processing (e.g., ChatGPT or Llama), trained to analyze life trajectories.
She created a breast cancer biomarker discovery program that demonstrated the association between hormones, lifestyle factors, and cancer risk. [ 2 ] [ 5 ] Her research demonstrated that women who used hormone replacement therapy were more likely to suffer from breast cancer than women who did not, and that the risk was highest amongst women ...
The year 2022 may go down in history as the year in which the United States got a second wind, as its main rivals on the world stage suffered serious setbacks.
