Recently, scientists reported that extracellular RNA (exRNA) from bacteria can persist in disinfected drinking water.
About Extracellular RNA:
The exRNA is RNA that exists outside cells.
It is found in body fluids such as blood, saliva, urine, and cerebrospinal fluid.
To survive outside the cell, exRNA travels in its own molecular containers that prevent enzymes from breaking it down before it reaches its destination.
These are heterogenous populations including small (e.g., miRNA) and long non-coding RNAs and coding RNAs (e.g., mRNA).
Functions:
It has been found to be part of a sophisticated long-distance communication system, allowing cells to deliver instructions to other cells, influencing behavior and gene activation.
It helps coordinate responses in the immune system, tissue repair, and development.
Medical significance:
It enables diagnosis of diseases like cancer and heart disease through RNA pattern testing in body fluids
It has potential for early detection and monitoring
