Insights

Cancer involves uncontrolled growth and spread, driven by specific genes. These metastasis genes, normally involved in healing and stress, are altered in cancer, leading to tumor progression and biomolecule dysregulation.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Cancer is defined by uncontrolled cell growth, evasion of senescence, and metastasis.
  • Tumor spread topology is influenced by genes involved in stress responses, inflammation, wound healing, and neovascularization.
  • These genes are typically nonessential for development but crucial in cancer progression.

Purpose of the Study:

  • To investigate the role of specific genes in cancer metastasis.
  • To understand the post-transcriptional modifications and dysregulation of these metastasis-associated genes in cancer.
  • To identify these genes as a unique group of cancer-related biomolecules.

Main Methods:

  • Analysis of gene expression patterns in cancer tissues.
  • Investigation of post-transcriptional gene modification mechanisms.
  • Splicing analysis of metastasis-related genes.

Main Results:

  • Identified a set of genes mediating cancer spread topology.
  • Demonstrated significant post-transcriptional modification of these gene products in cancer.
  • Observed dysregulation in gene expression and splicing of metastasis genes in cancerous conditions.

Conclusions:

  • Metastasis genes, physiologically involved in stress and healing, are key drivers of cancer spread.
  • Dysregulation at expression and splicing levels highlights their critical role in cancer.
  • These genes represent a distinct class of cancer-related biomolecules with therapeutic potential.

Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

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...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

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...
