lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

9.6K
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...

Inheritance of Chromatin Structures

7.2K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

Types of RNA01:20

Types of RNA

8.6K
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Non-LTR Retrotransposons03:18

Non-LTR Retrotransposons

13.0K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Area of Science:

  • Molecular Biology
  • Genetics
  • Epigenetics

Background:

  • Nuclear paraspeckle assembly transcript 1 (NEAT1) is a long non-coding RNA (lncRNA) found in mammalian cells.
  • NEAT1 is implicated in diverse biological and pathological processes.
  • Understanding NEAT1 regulation and its gene regulatory mechanisms is crucial.

Purpose of the Study:

  • To review the regulatory molecules and patterns controlling NEAT1 gene expression.
  • To elucidate the molecular mechanisms by which NEAT1 regulates its target genes.
  • To provide insights into NEAT1's role in gene regulation, stress, and disease.

Main Methods:

  • Literature review of studies on NEAT1 regulation and function.
  • Analysis of NEAT1's interaction with signal transducer and activator of transcription 3 (STAT3).
  • Examination of NEAT1's epigenetic regulation of downstream genes.

Main Results:

  • NEAT1 expression is regulated by STAT3.
  • Altered NEAT1 expression epigenetically modifies gene transcription during herpes simplex virus-1 infection and Alzheimer's disease.
  • NEAT1 functions as a sensor and effector in stress and disease.

Conclusions:

  • NEAT1 plays a central role in gene regulation.
  • NEAT1 is a key player in cellular responses to stress and disease.
  • Further research into NEAT1 regulation and function can inform therapeutic strategies.
