Insights

Steel factor (SLF) and c-Kit signaling pathways were investigated. Researchers identified a unique cell death mechanism (AECD) and explored econazole

Area of Science:

  • Cellular signaling pathways
  • Hematopoiesis
  • Cancer biology

Background:

  • Steel factor (SLF) and c-Kit form a crucial ligand-receptor pair.
  • This pair regulates the growth and activation of hemopoietic and non-hemopoietic cells.

Purpose of the Study:

  • Investigate downstream signaling pathways activated by SLF.
  • Identify differences in signaling between soluble and membrane-bound SLF.
  • Explore the role of PLC activation and calcium influx in supporting c-Kit positive cells.

Main Methods:

  • Analysis of SLF downstream signaling pathways.
  • Investigation of soluble vs. membrane-bound ligand effects.
  • Characterization of calcium (Ca2+) influx mechanisms.
  • Identification of factors influencing Activation Enhanced Cell Death (AECD) sensitivity.
  • Evaluation of econazole as a calcium channel blocker.

Main Results:

  • Discovered distinct signaling pathways for soluble and membrane-bound SLF.
  • Identified PLC activation and Ca2+ influx as critical for c-Kit positive cell support.
  • Defined Activation Enhanced Cell Death (AECD), a novel cell death pathway.
  • Identified factors contributing to AECD sensitivity and resistance.
  • Demonstrated econazole's potential as an anticancer therapeutic via calcium channel blockade.

Conclusions:

  • SLF-c-Kit signaling is complex, with variations based on ligand form.
  • Calcium influx plays a vital role in cell survival and is a target for AECD.
  • AECD represents a promising avenue for cancer therapy development.
  • Econazole shows potential as an anticancer agent by blocking calcium channels.

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
Amplifying Signals via Enzymatic Cascade01:22

Amplifying Signals via Enzymatic Cascade

When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze the...
PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...
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...
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...
