Insights

MYC drives cancer by altering RNA splicing. Targeting spliceosome components may treat MYC-driven tumors like lymphoma and breast cancer.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Genetics

Background:

  • RNA splicing alterations are common in human cancers.
  • The transcription factor MYC plays a critical role in malignant transformation.
  • A direct link between MYC and RNA splicing deregulation is emerging.

Purpose of the Study:

  • To investigate the role of spliceosome components in MYC-driven cancers.
  • To explore the potential of targeting the spliceosome as a therapeutic strategy.

Main Methods:

  • Analysis of gene expression data from lymphoma and breast cancer patients.
  • Functional studies to assess the impact of spliceosome component alterations on MYC-driven transformation.

Main Results:

  • Identification of essential spliceosome components in MYC-driven lymphoma and breast cancer.
  • Demonstration that these components are critical for malignant transformation.

Conclusions:

  • MYC directly influences RNA splicing, contributing to cancer development.
  • Targeting spliceosome components presents a promising therapeutic avenue for MYC-driven tumors.

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

Cancer-Critical Genes II: Tumor Suppressor Genes

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...

Abnormal Proliferation02:23

Abnormal Proliferation

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...

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...
