Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.9K
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...

Mismatch Repair01:20

Mismatch Repair

5.4K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

5.2K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Abnormal Proliferation02:23

Abnormal Proliferation

4.7K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Area of Science:

  • Hematology
  • Oncology
  • Genetics

Background:

  • Myelodysplastic syndromes (MDS) are complex blood disorders with diverse genetic profiles.
  • Targeted therapies are standard in other leukemias but not yet established for MDS.

Purpose of the Study:

  • To review current evidence on utilizing molecular aberrations in MDS.
  • To assess the potential for guiding therapy and improving patient outcomes in MDS.

Main Methods:

  • Literature review of recent studies on MDS molecular alterations.
  • Analysis of data linking genetic mutations to treatment response.

Main Results:

  • Molecular heterogeneity in MDS presents challenges for targeted treatment.
  • Emerging evidence suggests specific genetic markers may predict response to certain therapies.

Conclusions:

  • Personalizing MDS treatment based on molecular profiles is a promising future direction.
  • Further research is needed to integrate molecular-guided therapy into standard MDS care.
