Insights

BET inhibition is a new epigenetic therapy for cancers. Researchers found the Wnt signaling pathway drives resistance to this therapy in acute myeloid leukemia, offering a potential biomarker for treatment.

Area of Science:

  • Oncology
  • Epigenetics
  • Molecular Biology

Background:

  • BET inhibitors represent a novel epigenetic therapy for various cancers.
  • Therapeutic resistance remains a significant challenge, with limited understanding of its underlying mechanisms.

Purpose of the Study:

  • To investigate the mechanisms mediating sensitivity and resistance to BET inhibition in acute myeloid leukemia (AML).
  • To identify potential biomarkers for predicting response to BET inhibitor therapy.

Main Methods:

  • Analysis of two independent studies published in Nature.
  • Focus on molecular pathways implicated in BET inhibitor resistance in AML models.

Main Results:

  • Both studies independently identified the Wnt signaling pathway.
  • The Wnt pathway was implicated as a key driver of resistance to BET inhibition in AML.
  • Wnt pathway activation serves as a potential biomarker for therapeutic resistance.

Conclusions:

  • The Wnt signaling pathway is a critical determinant of response to BET inhibitors in AML.
  • Targeting or monitoring the Wnt pathway may overcome or predict resistance to epigenetic therapies.

Canonical Wnt Signaling Pathway02:54

Canonical Wnt Signaling Pathway

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...

Non-Canonical Wnt Signaling Pathways01:41

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
