  • What is biomarkers in bioinformatics?

    A biomarker is a biological molecule found in tissues or body fluids and can be used to predict or assess disease states.
    The aim of this thesis is to develop bioinformatics tools for discovery and evaluation of novel biomarkers from high-throughput datasets..

  • What is the current cancer biomarkers?

    Current Cancer Biomarkers is a comprehensive review on the status of biological markers for various types of cancer.
    It aims to update readers on current developments on the subject.
    The contents are divided into 5 sections covering a wide range of biomarkers and their diagnostic applications..

  • When should biomarker testing be done?

    Biomarker testing (also known as mutation, genomic, or molecular testing) is a way for the healthcare team to gather as much information as possible about a patient's unique lung cancer, ideally before treatment begins..

  • Where are cancer biomarkers found?

    According to the National Cancer Institute, a biomarker is “a biological molecule found in blood, other body fluids, or tissues that is a sign of a normal or abnormal process, or of a condition or disease,”(NCI) such as cancer..

  • Why are cancer biomarkers important?

    Each person's cancer has a unique pattern of biomarkers.
    Some biomarkers affect how certain cancer treatments work.
    Biomarker testing may help you and your doctor choose a cancer treatment for you.
    There are also other kinds of biomarkers that can help doctors diagnose and monitor cancer during and after treatment..

  • Bioinformatics also helps in identifying common biomarkers and differentially expressed genes in different cancer types which further improves the process of cancer diagnosis.
  • Biomarkers are measurable in body fluids and tissues and serve as indicators of health and disease status.Common cancer biomarkers include proteins, nucleic acids, metabolites, lipids, extracellular vesicles/exosomes, microRNAs, immune cells and others.
  • In this study, different bioinformatics tools (such as TCGA, GEPIA, UALCAN, MEXPRESS, and Metascape) have been used to assess the expression and prognostic value of the CREB1 gene.
  • NGS has not only shown tremendous potential in early cancer biomarker detection but also in supporting drug discovery efforts and guiding therapies.
    The applications for NGS have grown rapidly and their evolution has enabled the development of diagnostic and prognostic biomarkers for a wide range of disease areas.
Bioinformatics analysis of gene expression profiles is widely employed to identify DEGs as biomarkers for the occurrence and progression of cancer. This has facilitated the development of effective diagnostic and therapeutic strategies.

Are dynamic network biomarkers correlated with clinical informatics?

Dynamic network biomarkers were expected to be correlated with clinical informatics, including:

  • patient complaints
  • history
  • therapies
  • clinical symptoms and signs
  • physician’s examinations
  • biochemical analyses
  • imaging profiles
  • pathologies and other measurements [ 8 ].

    • Classification Methods

    Classification is a supervised learning method, where the model learns from a set of predefined samples with given class labels (training dataset).
    The knowledge inferred from this is applied to classify unknown samples (a test dataset) accordingly [13].
    In this work, three binary classification approaches were used to distinguish early-stage CRC p.

    Datasets

    Primary tumor samples from patients diagnosed with CRC disease from June 2010 to October 2017 were collected as part of a prospective biobanking project approved by the Ethical Committee of Hospital de Santa Maria, all procedures were performed in accordance with relevant guidelines.
    Patients were followed at the Oncology Division of Hospital Santa.

    What are Molecular Cancer biomarkers?

    Nature. 2011;469:156–157. doi:

  • 10.
  • 1038/469156a. [ PubMed] [ CrossRef] [ Google Scholar] Molecular cancer biomarkers are any measurable molecular indicator of risk of cancer, occurrence of cancer, or patient outcome.
    They may include:germline or somatic genetic variants, epigenetic signatures, transcriptional changes, and proteomic signatures..

    • What are the clinical applications of biomarkers?

    Clinical applications of biomarkers are extensive.
    They can be used as tools for cancer risk assessment, screening and early detection of cancer, accurate diagnosis, patient prognosis, prediction of response to therapy, and cancer surveillance and monitoring response.
    Therefore, they can help to optimize making decisions in clinical practice.

    Why is Cancer Bioinformatics important?

    Cancer bioinformatics is expected to play a more important role in the identification and validation of biomarkers, specific to clinical phenotypes related to early diagnoses, measurements to monitor the progress of the disease and the response to therapy, and predictors for the improvement of patient’s life quality.


    The Cancer Genome Project is part of the cancer, aging, and somatic mutation research based at the Wellcome Trust Sanger Institute in the United Kingdom.
    It aims to identify sequence variants/mutations critical in the development of human cancers.
    Like The Cancer Genome Atlas project within the United States, the Cancer Genome Project represents an effort in the War on Cancer to improve cancer diagnosis, treatment, and prevention through a better understanding of the molecular basis of the disease.
    The Cancer Genome Project was launched by Michael Stratton in 2000, and Peter Campbell is now the group leader of the project.
    The project works to combine knowledge of the human genome sequence with high throughput mutation detection techniques.
