microRNA: a compromising tool

Although what I am going to tell you is not a technical, instrument or material as such, but rather an interesting and small (but powerful) pharmaceutical weapon. First I will tell you about the microRNA (miRNA), these are small nucleotide sequences of non-coding RNA, that is, they do not synthesize proteins. Before, the scientists did not know very well the functions that these small fragments had in our organism, today it is known that they act as small machines for the regulation of gene expression, that is, they regulate the synthesis of proteins in cells.

Thanks to the study and new discoveries about these RNAs, the usefulness of these sequences in new gene therapies is being analyzed and evaluated to cure diseases caused by the abnormal expression of certain genes (such as viral, carcinogenic or other diseases).

It is of high importance in my career because it implies a compromising future in areas of research.

I chose this topic because it is something new, interesting and above all, it is something very curious for me.

I learned about this topic not long ago. It was in a couple of months ago, when the teacher told us about these sequences and their pharmaceutical utility.

It has a great impact in the field of health. Since it could be used to cure or treat diseases that today have no cure.

While it has a lot of advantages, if these sequences are not highly specific, they can cause serious illnesses in our body. For example, proteins of tumor cell suppressors can be inhibited.
