Zafira Castaño who
is a researcher and Doctor in Biochemistry from the University of
Navarra in Spain, discovered a connection between lower levels of αCP4
protein in early stages of lung cancer and may help make tumors grow.
Castaño noticed
that these αCP4 protein cells are found on tissue cells within a healthy
lung. However in a lung that was in first phase of cancer there was a
loss of this protein. The αCP4 protein was also lacking in 67% of the
tumors as well.
To confirm the
findings Castaño took samples of various cellular lines from different
kinds of lung tumors. She then introduced a series of the αCP4 protein
to the tumor tissues to see what would result. Some of the tumors
responded to the introduction of the protein. Tumor proliferations were
reduced with malignant tumors of large cells she noticed that their
ability to grow was reduced.
Hopefully this
research will help in the treatment for early stages of lung cancer in
the future. There still is a need to better detect lung cancer before
is develops into a late stage which is often deadly.
