The desired gene could be found
In each cell of the body,
But it expresses positively in few cells.

A trefoil factor encoding gene I mean,
It is found in the intestine
TFF1 is found exclusively in the intestine.

TFF1 is also known as pS2
Meaning protein for specificity 2,
2nd gene discovered for specificity protein.

TFF1 protects gastrointestinal mucosa,
From any injuries that may result
Out of pathogenic invasion.

The trefoil factor 2 encoding gene
Is also found in the intestine
But TFF2 plays a different role in the body.

TFF2 is also known as pS1
Meaning protein for specificity 1,
1st gene discovered for specificity protein.

TFF2 protects gastrointestinal mucosa,
From any cancer that may result
Out of oncogenic activity.

And the third trefoil factor encoding gene,
It is only expressed in the female womb
But TFF3 is crucial for a successful pregnancy.

I love my field of study very much
And I respect my major guide,
Dr Ashok Kumar Mohanty, he is so wise.
