Insights

This study used proteomics to identify proteins altered in NIH3T3 cells transformed by oncogenic H-RasV12. Gankyrin was found to be upregulated, implicating its pathway in Ras-activated transformation.

Area of Science:

  • Proteomics
  • Cell Biology
  • Oncology

Background:

  • Oncogenic H-RasV12 transformation drives significant cellular changes.
  • Understanding proteome alterations is crucial for cancer research.

Purpose of the Study:

  • To systematically analyze proteome changes in NIH3T3 cells upon oncogenic H-RasV12 transformation.
  • To identify novel proteins involved in Ras-mediated transformation.

Main Methods:

  • Proteomics approach for systematic proteome analysis.
  • Reverse transcription polymerase chain reaction (RT-PCR) for mRNA abundance analysis.

Main Results:

  • Identified 44 proteins associated with Ras-mediated transformation.
  • Discovered 28 previously unreported proteins.
  • Observed concomitant changes in mRNA abundance for approximately 44% of identified proteins.
  • Found significant upregulation of gankyrin.

Conclusions:

  • Gankyrin pathway is implicated in Ras-activated transformation.
  • Proteomics is a valuable tool for dissecting cellular transformation mechanisms.

The Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:
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...
Proteomics01:33

Proteomics

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term proteomics...
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 daughter...
