Insights

Extracellular microRNAs (miRNAs) are key regulators of gene expression implicated in cancer development and progression. Research is exploring their potential as non-invasive biomarkers and novel therapeutic targets for cancer treatment.

Area of Science:

  • Molecular Biology
  • Genetics
  • Cancer Research

Background:

  • Extracellular RNAs (exRNAs) are transcripts released from cells, regulating cellular processes via gene expression.
  • MicroRNAs (miRNAs), a class of non-coding exRNAs, are crucial regulators of gene expression.
  • Dysregulated miRNAs are implicated in cancer initiation, progression, metastasis, and therapeutic response.

Purpose of the Study:

  • To review the role of extracellular microRNAs (miRNAs) in cancer.
  • To discuss the potential of miRNA profiling for cancer diagnosis and prognostication.
  • To explore the therapeutic applications of miRNAs in cancer treatment.

Main Methods:

  • Literature review of pre-clinical and human studies on extracellular RNAs and miRNAs in cancer.
  • Analysis of current research on miRNA profiling for cancer biomarkers.
  • Evaluation of emerging miRNA-based cancer therapeutic strategies.

Main Results:

  • miRNAs are frequently dysregulated in various cancers.
  • miRNA profiling shows promise as a non-invasive diagnostic and prognostic tool.
  • miRNA antagonists and mimics demonstrate pre-clinical efficacy in cancer models.

Conclusions:

  • Extracellular miRNAs play significant roles in cancer biology.
  • miRNA-based approaches offer novel avenues for cancer detection and therapy.
  • Further development is needed for clinical translation of miRNA-based cancer strategies.

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

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...

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...

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...

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...
