Insights

Protein arginine methyltransferases (PRMTs) are key in breast cancer progression. Targeting PRMTs offers a promising strategy to overcome treatment failures and reduce tumor recurrence in breast cancer patients.

Area of Science:

  • Oncology
  • Biochemistry
  • Molecular Biology

Background:

  • Breast cancer is a leading cause of cancer death in women globally.
  • Current treatments for breast cancer have limitations, with high rates of treatment failure and tumor recurrence.
  • Novel therapeutic targets are urgently needed to improve breast cancer treatment outcomes.

Purpose of the Study:

  • To review the current understanding of protein arginine methyltransferases (PRMTs) in breast cancer.
  • To explore the role of PRMTs in cellular pathways critical to breast cancer development and progression.
  • To provide a rationale for targeting PRMTs as a novel therapeutic strategy for breast cancer.

Main Methods:

  • Literature review of existing research on PRMTs and breast cancer.
  • Analysis of the dysregulation of PRMT expression and activity in breast cancer.
  • Examination of the involvement of PRMTs in key cellular processes relevant to cancer.

Main Results:

  • PRMTs are enzymes catalyzing arginine methylation, involved in diverse cellular functions.
  • Dysregulated expression and activity of PRMTs are observed in breast cancer.
  • Altered PRMTs significantly impact cellular pathways driving breast cancer initiation and advancement.

Conclusions:

  • PRMTs play a critical role in breast cancer pathogenesis.
  • The dysregulation of PRMTs presents a significant therapeutic vulnerability.
  • Targeting PRMTs holds potential as a novel strategy to treat breast cancer and improve patient prognosis.

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...

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...

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...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

Pharmacogenetics of Phase II Enzymes: N-acetyltransferase, Thiopurine S-methyltransferase, UDP-glucuronosyltransferase

Phase II biotransformation reactions are essential for detoxifying and eliminating xenobiotics, including many pharmaceutical compounds. These reactions typically involve conjugation, the covalent attachment of polar endogenous groups such as glucuronic acid, sulfate, methyl, or acetyl moieties to functional groups introduced during Phase I metabolism. The resulting conjugates are more water-soluble, enabling efficient renal or biliary excretion.The major classes of Phase II enzymes include...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
