Insights

Circular RNAs (circRNAs) are key players in cancer, influencing proliferation, metastasis, and drug resistance. Research highlights their potential as stable biomarkers for cancer diagnosis and therapy.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Circular RNAs (circRNAs) are increasingly recognized as crucial regulators in cancer biology.
  • Their unique covalently closed loop structure confers high stability and tissue-specific expression.
  • circRNAs influence fundamental cancer hallmarks like proliferation, apoptosis, metastasis, and drug resistance.

Purpose of the Study:

  • To review the multifaceted roles of circRNAs in cancer.
  • To explore their potential as diagnostic and prognostic biomarkers.
  • To discuss emerging therapeutic strategies targeting circRNAs.

Main Methods:

  • Literature review of studies on circRNA functions in cancer.
  • Analysis of RNA sequencing and bioinformatics data for circRNA identification.
  • Evaluation of clinical data regarding circRNA specificity and sensitivity.

Main Results:

  • circRNAs function via miRNA sponging, RNA-binding protein interactions, and modulation of transcription/splicing.
  • Advances in sequencing and bioinformatics facilitate circRNA discovery across cancer types.
  • circRNAs show promise as sensitive and specific biomarkers in clinical samples.

Conclusions:

  • circRNAs represent a significant area of research in oncology with potential for improved diagnostics and therapeutics.
  • Further investigation is required to elucidate precise mechanisms and gather more clinical evidence.
  • Understanding circRNAs may lead to novel strategies for enhancing patient outcomes in cancer care.

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...

MicroRNAs01:22

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...

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.

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
