mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.5K
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...

Cancer-Critical Genes II: Tumor Suppressor Genes

9.3K
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...

lncRNA - Long Non-coding RNAs

9.7K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Abnormal Proliferation02:23

Abnormal Proliferation

5.0K
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...

Master Transcription Regulators02:23

Master Transcription Regulators

7.6K
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Tumor Progression02:07

Tumor Progression

7.1K
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...

Area of Science:

  • Oncology
  • Molecular Biology
  • Bioinformatics

Background:

  • Extracellular matrix (ECM) remodeling is crucial for cancer invasion and metastasis.
  • Matrix metalloproteinases (MMPs) are key ECM modulators implicated in tumor progression.
  • Tissue inhibitors of metalloproteinases (TIMPs), including TIMP2, regulate MMP activity and may have anti-tumor roles.

Purpose of the Study:

  • To investigate the role of TIMP2 in tumor progression by analyzing gene co-expression patterns.
  • To identify potential therapeutic targets and biomarkers related to TIMP2 function in the tumor microenvironment.

Main Methods:

  • Utilized The Cancer Genome Atlas and Genotype-Tissue Expression data for breast and lung carcinomas.
  • Analyzed transcriptome-wide correlations with TIMP2 expression in tumor versus normal tissues.
  • Performed bioinformatic analysis to identify co-expressed matrix and matrix-associated genes.

Main Results:

  • Identified a list of genes significantly correlated with TIMP2 expression in tumor tissues.
  • Bioinformatic analysis revealed a core set of matrix and matrix-associated genes linked to TIMP2.
  • These findings suggest potential modulators of TIMP2 function and ECM structure.

Conclusions:

  • TIMP2's role in tumor progression may be mediated by its interaction with specific matrix genes.
  • The identified gene set represents potential biomarkers for the tumor microenvironment.
  • These matrix-associated genes are promising targets for future therapeutic strategies against cancer.
