Experimental RNAi

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...

Epigenetic Regulation

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

lncRNA - Long Non-coding RNAs

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 RNAs

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...

Area of Science:

Molecular Biology
Developmental Biology
Neuroscience

Background:

Multicellular organisms exhibit remarkable molecular complexity with hundreds of cell types sharing a genome.
Epigenetic signals are crucial for maintaining distinct cell identities and regulating gene expression during cell division.
Epigenetic mechanisms are increasingly recognized for their role in brain function, impacting neuroscience and medicine.

Purpose of the Study:

To explore the role of epigenetic signals in maintaining cellular complexity and function.
To investigate the potential of nonconventional model organisms for understanding epigenetic regulation.
To highlight the relevance of studying social insects for insights into conserved molecular pathways.

Main Methods:

The study proposes the development of new technologies for epigenetic research.
It advocates for the study of nonconventional model organisms, specifically eusocial insects like ants and honeybees.
Focuses on analyzing the distinct epigenetic differences in insect castes.

Main Results:

Eusocial insects display extreme polyphenism and polyethism, resulting in distinct castes with specialized functions.
These insects possess sharp epigenetic differences that can be experimentally dissected.
The molecular pathways underlying these differences may be conserved across species, including humans.

Conclusions:

Epigenetic differences in social insects provide a powerful model for dissecting conserved molecular pathways.
Understanding these pathways has significant implications for neuroscience and medicine.
Further research in nonconventional models can advance our knowledge of fundamental biological processes.
