Insights

MicroRNA-145-5p (miR-145-5p) acts as a tumor suppressor in many cancers but can be upregulated in others. This microRNA also impacts non-malignant conditions like asthma and arthritis.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • MicroRNA-145-5p (miR-145-5p), encoded by the MIR145 gene on chromosome 5, is implicated in various diseases.
  • It is primarily recognized as a tumor suppressor in multiple cancers, including bladder, breast, cervical, cholangiocarcinoma, renal, and gastrointestinal cancers.

Purpose of the Study:

  • To review the current literature on the multifaceted roles of miR-145-5p.
  • To consolidate understanding of its involvement in both malignant and non-malignant conditions.

Main Methods:

  • Literature review of studies investigating miR-145-5p.
  • Analysis of its expression patterns and functional roles in disease pathogenesis.

Main Results:

  • miR-145-5p generally functions as a tumor suppressor, but its upregulation has been observed in certain cancers.
  • Evidence suggests miR-145-5p influences the pathogenesis of non-malignant conditions such as aplastic anemia, asthma, cerebral ischemia/reperfusion injury, diabetic nephropathy, rheumatoid arthritis, and Sjögren syndrome.

Conclusions:

  • miR-145-5p exhibits complex roles in disease, acting as a tumor suppressor in many cancers while also affecting non-malignant disorders.
  • Further research is warranted to fully elucidate the therapeutic potential of targeting miR-145-5p.

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...

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...

piRNA - Piwi-interacting RNAs

PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

Alternative RNA Splicing02:18

Alternative RNA Splicing

Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

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...

Experimental RNAi02:15

Experimental 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...
