Insights

A newly discovered microRNA within intron 3 of the high mobility group AT-hook 2 (HMGA2) gene may cooperate with HMGA2 in stem cell functions and benign tumor development.

Area of Science:

  • Molecular Biology
  • Genetics
  • Cancer Biology

Background:

  • High mobility group protein HMGA2 is crucial in stem cells and linked to benign tumors like uterine leiomyomas and lipomas.
  • HMGA2's role in chromatin structure and cell proliferation is well-established.

Purpose of the Study:

  • To identify and characterize novel functional elements within the HMGA2 gene.
  • To investigate the potential role of intronic regions in HMGA2-related functions.

Main Methods:

  • Bioinformatic analysis to identify conserved regions within HMGA2 introns.
  • Sequence analysis to predict microRNA encoding potential.
  • Comparative genomics to assess evolutionary conservation.

Main Results:

  • A highly conserved region within intron 3 of HMGA2 was identified.
  • This region encodes a microRNA (miRNA).
  • The miRNA is co-expressed with HMGA2, suggesting a functional relationship.

Conclusions:

  • The HMGA2 gene harbors a conserved intronic microRNA.
  • This intronic miRNA may play a cooperative role with HMGA2 in both normal stem cell biology and aberrant tumor formation.
  • Further research is warranted to elucidate the specific mechanisms of this miRNA-HMGA2 interaction.

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Multi-species Conserved Sequences

Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved DNA...

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 (lncRNA)...
Heterochromatin02:38

Heterochromatin

The extent of chromatin compaction can be studied by staining chromatin using specific DNA binding dyes. Under the microscope, the dense-compacted regions that take up more dye are called heterochromatin. Heterochromatin is further classified into two forms – constitutive heterochromatin and facultative heterochromatin.
Constitutive heterochromatin: It is a highly compact region of chromatin that is mostly concentrated in the centromere and telomere. Unlike euchromatin, the amino acid at 9th...
