Insights

Epigenetic modulators like DNMT and HDAC inhibitors show promise for treating breast cancer (BC), especially drug-resistant and triple-negative types (TNBC), with few side effects.

Area of Science:

  • Oncology
  • Epigenetics
  • Molecular Biology

Background:

  • Breast cancer (BC) remains a leading cause of cancer mortality worldwide.
  • Drug resistance and lack of targeted therapies for triple-negative breast cancer (TNBC) hinder progress.
  • High proliferation rates in TNBC contribute to its poor prognosis.

Purpose of the Study:

  • To explore novel therapeutic strategies for overcoming BC drug resistance and treating TNBC.
  • To investigate the potential of epigenetic modulators in BC therapy.
  • To review current research on epigenetic modulators in BC treatment.

Main Methods:

  • Review of in vitro, preclinical, and clinical studies on epigenetic modulators in BC.
  • Analysis of gene expression profiles in different BC subtypes.
  • Focus on DNA Methyl Transferase (DNMT) and Histone DeAcetylase (HDAC) inhibitors.

Main Results:

  • Epigenetic modulators demonstrate a positive effect on various BC types, including drug-resistant cells.
  • DNMT and HDAC inhibitors show efficacy with a favorable side effect profile.
  • Preliminary results suggest potential for new BC therapies.

Conclusions:

  • Epigenetic modulators represent a promising therapeutic avenue for breast cancer.
  • Targeting epigenetic mechanisms may overcome drug resistance and address TNBC.
  • Further investigation into these compounds could lead to improved BC treatments.

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Epigenetic Regulation01:37

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

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...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
