lncRNA - Long Non-coding RNAs

lncRNA - Long Non-coding RNAs

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...

Cancer-Critical Genes II: Tumor Suppressor Genes

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...

Area of Science:

Oncology
Bioinformatics
Genomics

Background:

Squamous lung cancer is a prevalent malignancy with an unclear oncogenesis mechanism.
Understanding the genetic underpinnings of squamous lung cancer is crucial for developing targeted therapies.

Purpose of the Study:

To identify candidate genes associated with squamous lung cancer using a bioinformatics approach.
To elucidate the molecular mechanisms driving squamous lung cancer development.

Main Methods:

Utilized publicly available microarray data (GSE3268) from the Gene Expression Omnibus (GEO).
Performed differential gene expression analysis using R software.
Constructed gene regulatory networks via transcriptome network analysis, incorporating data from the Transcriptional Regulatory Element Database.

Main Results:

Identified six candidate genes: SPI1, FLI1, FOS, ETS2, EGR1, and PPARG.
Five of the identified genes (FOS, ETS2, EGR1, PPARG) have prior associations with lung cancer.
SPI1 and FLI1 were highlighted as potentially novel genes in squamous lung cancer pathogenesis.

Conclusions:

Transcriptome network analysis is an effective method for identifying candidate disease genes.
SPI1 and FLI1 warrant further investigation as potential key players in squamous lung cancer development.
