Summary
General transcription factor II E (GTF2E) knockdown altered gene expression, impacting cellular processes and disease development. GTF2E1 knockdown reduced cell viability and affected genes linked to colon cancer and atherosclerosis.
Area of Science:
- Molecular Biology
- Genetics
- Cancer Research
Background:
- General transcription factor II E (GTF2E) is linked to colon cancer and trichothiodystrophy.
- The global effect of GTF2E on cellular processes remains undercharacterized.
Purpose of the Study:
- Investigate GTF2E's effect on gene transcription levels.
- Identify cellular processes and diseases associated with GTF2E.
Main Methods:
- Whole transcriptome analysis using RNA sequencing on HCT116 cells with GTF2E1 knockdown.
- siRNA-mediated knockdown of GTF2E1 at 30 nM concentration.
- Cell viability assessment using MTS assay.
Main Results:
- GTF2E1 knockdown resulted in 166 differentially expressed genes (66 upregulated, 100 downregulated).
- Identified enriched Gene Ontology term: carbohydrate binding.
- Associated GTF2E1 knockdown with B-cell chronic lymphocytic leukemia (B-CLL), colon carcinoma, and atherosclerosis development.
- Observed a decrease in cell viability upon GTF2E1 knockdown.
Conclusions:
- GTF2E1 knockdown alters the expression of genes involved in atherosclerosis, colon carcinoma, and B-CLL.
- Findings suggest regulatory roles of GTF2E in disease pathogenesis.

5.1K
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

3.4K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

01:56Riboswitches
8.0K
Riboswitches are non-coding mRNA domains that regulate the transcription and translation of downstream genes without the help of proteins. Riboswitches bind directly to a metabolite and can form unique stem-loop or hairpin structures in response to the amount of the metabolite present. They have two distinct regions – a metabolite-binding aptamer and an expression platform.
The aptamer has high specificity for a particular metabolite which allows riboswitches to specifically regulate...

01:23Regulation of Expression at Multiple Steps
841
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

10.6K
Transcription elongation is a dynamic process that alters depending upon the sequence heterogeneity of the DNA being transcribed. Hence, it is not surprising that the elongation complex's composition also varies along the way while transcribing a gene.
The transcription elongation is regulated via pausing of RNA polymerase on several occasions during transcription. In bacteria, these halts are necessary because the transcription of DNA into mRNA is coupled to the translation of that mRNA...
