The Eukaryotic Promoter Region02:40

The Eukaryotic Promoter Region

18.9K
The eukaryotic promoter region is a segment of DNA located upstream of a gene. It contains an RNA polymerase binding site, a transcription start site, and several cis-regulatory sequences.  The proximal promoter region is located in the vicinity of the gene and has cis-regulatory sequences and the core promoter. The core promoter is the binding site for RNA polymerase and is usually located between -35 and +35 nucleotides from the transcription start site. The distal promoter regions are...

Transcription Factors

82.8K
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...

Eukaryotic RNA Polymerases

27.1K
RNA Polymerase (RNAP) is conserved in all animals, with bacterial, archaeal, and eukaryotic RNAPs sharing significant sequence, structural, and functional similarities. Among the three eukaryotic RNAPs, RNA Polymerase II is most similar to bacterial RNAP in terms of both structural organization and folding topologies of the enzyme subunits. However, these similarities are not reflected in their mechanism of action.
All three eukaryotic RNAPs require specific transcription factors, of which the...

RNA Polymerase II Accessory Proteins02:36

RNA Polymerase II Accessory Proteins

11.0K
Proteins that regulate transcription can do so either via direct contact with RNA Polymerase or through indirect interactions facilitated by adaptors, mediators, histone-modifying proteins, and nucleosome remodelers. Direct interactions to activate transcription is seen in bacteria as well as in some eukaryotic genes. In these cases, upstream activation sequences are adjacent to the promoters, and the activator proteins interact directly with the transcriptional machinery. For example, in...

Master Transcription Regulators02:23

Master Transcription Regulators

7.8K
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...

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Circular RNAs (circRNAs) are prevalent in mammals and play roles in tumor development.
  • has_circ_0015758 (circ-CFH), a circRNA homologous to complement factor H (CFH), has an uncharacterized function in glioma.
  • Understanding circ-CFH's role is crucial for advancing glioma research.

Purpose of the Study:

  • To investigate the function of circ-CFH in glioma progression.
  • To elucidate the molecular mechanisms underlying circ-CFH's role in glioma.
  • To identify potential therapeutic targets for glioma.

Main Methods:

  • Quantitative real-time PCR (qRT-PCR) to measure circ-CFH, miR-149, and Akt1 mRNA levels.
  • Circ-CFH knockdown models using siRNAs to assess effects on cell proliferation.
  • CCK-8, colony formation assays, in vivo experiments, and luciferase reporter assays to determine function and interactions.

Main Results:

  • Circ-CFH expression was significantly upregulated in glioma tissues and cell lines, correlating with tumor grade.
  • Knockdown of circ-CFH inhibited glioma cell proliferation and colony formation.
  • Luciferase assays confirmed circ-CFH acts as a miR-149 sponge, and AKT1 was identified as a direct target of this axis.

Conclusions:

  • Circ-CFH promotes glioma progression by sponging miR-149 and modulating the AKT1 signaling pathway.
  • The circ-CFH/miR-149/AKT1 regulatory axis represents a promising therapeutic target for glioma.
  • Further research into this axis could lead to novel treatment strategies for glioma patients.
