Insights

MicroRNA-20a (miR-20a) shows promise as a biomarker for colorectal cancer (CRC) diagnosis and treatment monitoring. This research explores miR-20a

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Colorectal cancer (CRC) lacks specific diagnostic and treatment biomarkers.
  • MicroRNAs (miRs) are key regulators of gene expression involved in disease.
  • Abnormal miR-20a expression is implicated in various cancers, including CRC.

Purpose of the Study:

  • To investigate the role and underlying mechanisms of miR-20a in colorectal cancer.
  • To evaluate miR-20a as a potential diagnostic and prognostic biomarker for CRC.
  • To explore miR-20a's utility in monitoring chemotherapy resistance.

Main Methods:

  • Analysis of miR-20a expression in CRC tissues, serum, plasma, and feces.
  • Correlation of miR-20a levels with CRC diagnosis and progression.
  • Assessment of miR-20a expression changes during chemotherapy.

Main Results:

  • Elevated miR-20a levels are consistently found in CRC patient samples (tissues, serum, plasma).
  • miR-20a is detectable in feces, showing high sensitivity for CRC detection.
  • Changes in miR-20a expression correlate with chemotherapy resistance.

Conclusions:

  • miR-20a holds significant potential as a non-invasive biomarker for CRC diagnosis.
  • miR-20a may serve as an indicator for monitoring treatment response and resistance.
  • Targeting miR-20a could offer a novel therapeutic strategy for colorectal cancer.

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...

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Mechanisms of Retrovirus-induced Cancers01:51

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

lncRNA - Long Non-coding RNAs02:39

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...
