Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

8.0K
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...

Abnormal Proliferation02:23

Abnormal Proliferation

5.4K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Negative Regulator Molecules01:23

Negative Regulator Molecules

39.2K
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.

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

6.4K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

6.2K
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...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

6.5K
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...

Area of Science:

  • Pediatric Oncology
  • Molecular Biology
  • Cancer Research

Background:

  • Neuroblastoma is a common childhood cancer with high mortality.
  • Focal adhesion kinase (FAK) drives neuroblastoma progression.
  • p53, often wild type, functions poorly as a tumor suppressor in neuroblastoma.

Purpose of the Study:

  • To investigate the interaction and co-regulation of FAK and p53 in neuroblastoma.
  • To evaluate the combined effect of FAK inhibition and p53 activation on neuroblastoma cells.

Main Methods:

  • Investigated FAK and p53 interaction and expression control.
  • Assessed the impact of combined FAK inhibition and p53 activation on neuroblastoma cell survival.

Main Results:

  • Confirmed interaction between FAK and p53 in neuroblastoma.
  • Demonstrated that FAK and p53 mutually regulate each other's expression.
  • Showed synergistic reduction in neuroblastoma cell survival upon combined FAK inhibition and p53 activation.

Conclusions:

  • FAK and p53 play a coordinated role in neuroblastoma tumorigenesis.
  • Combined FAK inhibition and p53 activation represent a promising therapeutic strategy for neuroblastoma.
  • Further research into FAK and p53 pathways may yield novel pediatric cancer treatments.
