Insights

Cancer cells evade death, but RIPK3, a necroptosis kinase, plays a key role in preventing acute myeloid leukemia development, according to new research.

Area of Science:

  • Oncology
  • Cell Biology
  • Molecular Biology

Background:

  • Cancer cells exhibit a key characteristic of evading cell death pathways.
  • Necroptosis is a regulated form of inflammatory cell death.
  • Acute myeloid leukemia (AML) is a cancer of the blood and bone marrow.

Purpose of the Study:

  • To investigate the role of receptor-interacting protein kinase 3 (RIPK3) in the development of acute myeloid leukemia.
  • To understand how RIPK3 influences cancer cell death evasion.

Main Methods:

  • The study identified RIPK3 as a crucial kinase involved in necroptosis.
  • Researchers examined the function of RIPK3 in the context of acute myeloid leukemia development.

Main Results:

  • RIPK3 was found to be essential in inhibiting the development of acute myeloid leukemia.
  • The kinase activity of RIPK3 is critical for its tumor-suppressive function in AML.

Conclusions:

  • RIPK3 plays a significant role in preventing the initiation and progression of acute myeloid leukemia.
  • Targeting RIPK3 or modulating necroptosis pathways may offer novel therapeutic strategies for AML.

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Replicative Cell Senescence02:15

Replicative Cell Senescence

Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...
