Abstract
Summary and Conclusion
The aim of this work was concerned with role of serum
circulating lliicroRNA 21 as a novel non invasive biomarker in
different stages of human breast cancer.
This study was carried out on 40 subjects. They were
classified into the following groups:
~ Group I: 30 breast cancer patients with different stages.
~ Group 11:10 healthy volunteers as a control group.
I
All subjects in the present study were subjected to the following:
1. History taking and clinical examination
I 2. Laboratory workup:
I
a) Routine laboratory investigations:
i. CBC,ESR.
I I ii. Serum LDH.
I ’iii. Determination of carbohydrate antigen (CA 15.3).
b) Specific investigations for assessment of circulating micro
RNA 21 (miR-21):
By real time polymerase chain reaction (RT-PCR) for all
subjects included in the pt;.esent study.
