Insights

This study introduces a novel systems biology approach to identify cancer-causing genetic changes by analyzing disrupted molecular interactions. The method effectively pinpoints oncogenic lesions and drug targets in B-cell lymphomas.

Area of Science:

  • Computational biology
  • Cancer biology
  • Systems biology

Background:

  • Identifying oncogenic lesions computationally remains a challenge.
  • Existing methods do not adequately model molecular interaction networks in cancer.
  • Understanding dysregulated interactions is crucial for cancer insights.

Purpose of the Study:

  • To introduce a systems biology approach for identifying oncogenic lesions.
  • To analyze dysregulated molecular interactions in specific tumor phenotypes.
  • To identify targets of molecular perturbations in human cells.

Main Methods:

  • Utilized a systems biology strategy analyzing dysregulated molecular interactions.
  • Employed the B-cell interactome (BCI) and microarray expression profiles.
  • Applied the method to non-Hodgkin's lymphomas and CD40 ligand-perturbed samples.

Main Results:

  • The approach provided insights into tumorigenesis.
  • Successfully identified targets of molecular perturbations.
  • Consistently ranked known genes within the top 20 (0.3%).
  • Outperformed conventional methods in 3 out of 4 cases.

Conclusions:

  • The proposed systems biology method enhances the identification of oncogenic lesions.
  • This approach is effective for pinpointing molecular perturbation targets.
  • It offers a valuable extension to existing computational cancer biology tools.

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
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 specific...
Cancer-Critical Genes I: Proto-oncogenes01:33

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
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...
