Insights

Molecular biomarkers like microRNAs (miRNAs) are revolutionizing cancer diagnosis and treatment. These small RNAs and other molecules aid in early detection, risk assessment, and personalized medicine strategies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biomarker Discovery

Background:

  • Cancer diagnosis is shifting towards molecular biomarker integration.
  • Alterations in DNA, RNA, microRNAs (miRNAs), and proteins are key indicators.
  • microRNAs (miRNAs) are small non-coding RNAs crucial in cancer regulation.

Purpose of the Study:

  • To highlight the role of molecular biomarkers in modern cancer diagnosis.
  • To explore the diagnostic and therapeutic potential of miRNAs.
  • To discuss the application of novel diagnostic tools in personalized medicine.

Main Methods:

  • High-throughput techniques for identifying altered cellular molecules.
  • Analysis of various body specimens (blood, tissues) for biomarkers.
  • Development of innovative antibodies for protein detection (immunohistochemistry).

Main Results:

  • Molecular alterations, including miRNAs, are significantly altered in cancers.
  • Biomarkers are applicable across diverse specimens for clinical use.
  • Novel tools aid in diagnosis, risk stratification, and personalized therapy.

Conclusions:

  • Molecular biomarkers represent a paradigm shift in cancer diagnosis.
  • microRNAs (miRNAs) show promise as diagnostic markers and therapeutic targets.
  • New diagnostic tools enhance prognostic assessment and personalized medicine.

Cancer Therapies02:49

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Nursing Diagnosis01:22

Nursing Diagnosis

Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.
The nursing diagnosis focuses on evidence-based...

Gene Therapy00:59

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Overview of Advanced Functional Groups


Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
Types of Advanced Functional Groups
The table below summarizes some of the major functional groups in organic chemistry.
