Insights

Phosphatase and tensin homologue (PTEN) is crucial in many diseases. Noncoding RNAs (ncRNAs) regulate PTEN expression, offering new therapeutic targets for conditions involving abnormal PTEN levels.

Area of Science:

  • Molecular Biology
  • Genetics
  • Biochemistry

Background:

  • Phosphatase and tensin homologue (PTEN) is a key tumor suppressor involved in critical cell signaling pathways like PI3K/Akt.
  • Dysregulation of PTEN contributes to the pathogenesis of various diseases, including cancer and neurodevelopmental disorders.
  • PTEN's role highlights its potential as a disease biomarker and therapeutic target.

Purpose of the Study:

  • To review the current understanding of how noncoding RNAs (ncRNAs) regulate PTEN expression.
  • To explore the epigenetic and post-transcriptional mechanisms by which ncRNAs control PTEN levels.
  • To discuss the implications of ncRNA-mediated PTEN regulation for disease treatment.

Main Methods:

  • Literature review of studies investigating ncRNA-PTEN interactions.
  • Analysis of epigenetic and post-transcriptional regulatory mechanisms.
  • Synthesis of findings on ncRNA roles in PTEN expression.

Main Results:

  • Noncoding RNAs (ncRNAs) epigenetically and post-transcriptionally regulate PTEN expression.
  • Specific ncRNAs have been identified as modulators of PTEN levels.
  • These regulatory interactions are implicated in various disease contexts.

Conclusions:

  • PTEN regulation by ncRNAs is a significant area of research.
  • Understanding these ncRNA-PTEN interactions can lead to novel therapeutic strategies.
  • Targeting ncRNAs offers a promising avenue for treating diseases associated with abnormal PTEN expression.

Regulation of Expression Occurs at Multiple Steps02:24

Regulation of Expression Occurs at Multiple Steps

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

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...

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

Regulation of Expression at Multiple Steps01:23

Regulation of Expression at Multiple Steps

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...
