Summary
Increased RNA polymerase III (Pol III) output significantly impacts cell transformation. This study reveals the crucial role of Pol III in cancer development.
Area of Science:
- Molecular Biology
- Cancer Research
- Biochemistry
Background:
- RNA polymerase III (Pol III) synthesizes essential small non-coding RNAs like tRNA and 5S rRNA.
- Elevated Pol III activity is a hallmark of many transformed and cancerous cells.
- The functional significance of increased Pol III transcription in cancer remains incompletely understood.
Approach:
- Investigating the regulatory mechanisms of Pol III-dependent transcription.
- Analyzing the impact of Pol III product levels on cellular transformation processes.
- Utilizing molecular and cellular assays to quantify Pol III output and transformation phenotypes.
Key Points:
- Pol III transcription is frequently upregulated in cancer cells.
- The precise contribution of this upregulation to malignant transformation requires further elucidation.
- Emerging data indicate a substantial role for Pol III activity in driving cellular transformation.
Conclusions:
- Pol III-mediated transcription plays a critical role in cellular transformation.
- Understanding Pol III regulation in cancer offers potential therapeutic targets.
- Further research is warranted to fully delineate Pol III's oncogenic functions.

01:32RNA Splicing
53.3K
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

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...

12.3K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

02:39lncRNA - Long Non-coding RNAs
7.5K
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...

02:15Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
