    Insights

    RNA interference (RNAi) regulates gene expression and is crucial for understanding cancer. Modified RNAi therapeutics show promise for future cancer chemotherapy.

    Area of Science:

    • Molecular Biology
    • Genetics
    • Cancer Research

    Background:

    • RNA interference (RNAi) is a natural biological process regulating gene and protein expression for homeostasis.
    • Non-coding RNAs (ncRNAs), including microRNAs, are expressed widely, with specific microRNAs differing between tumor and non-tumor tissues.

    Purpose of the Study:

    • To explore the role of RNA interference (RNAi) in cancer biology.
    • To highlight the potential of RNAi-based strategies for cancer treatment.

    Main Methods:

    • Review of RNA interference mechanisms and their involvement in cancer pathways.
    • Analysis of ncRNA expression patterns in tumor versus non-tumor tissues.
    • Evaluation of RNAi-based therapeutic strategies.

    Main Results:

    • RNAi is essential for dissecting cancer development, growth, and metastasis.
    • Specific microRNAs show altered expression in cancerous tissues, indicating potential as biomarkers.
    • RNAi has identified key tumor-specific gene targets for chemotherapy.

    Conclusions:

    • RNA interference is a powerful tool for cancer research and target identification.
    • Development of novel small inhibitory RNAs and improved delivery systems are key for advancing RNAi-based cancer therapeutics.

    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...

    RNA Interference

    RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
    This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

    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)...

    piRNA - Piwi-interacting RNAs02:57

    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...
