INTRODUCTIONINTRODUCTION
Bad folding, synthesizing and aggregation of proteins contributes to decrease the cell’s ability to live and reproduce.
In cancer is possible to see many chromosomal aberrations, but unlike normal cells, cancer cells can strongly grow and reproduce.
NEW DISCOVERIES IN NEW DISCOVERIES IN CELL AGINGCELL AGING
NEW DISCOVERIES IN CELL NEW DISCOVERIES IN CELL AGINGAGING
The researchers have quantified the effect of protein aggregation on cell aging.
Protein aggregations are important in different neurodegenerative deseases.
NEW DISCOVERIES IN CELL NEW DISCOVERIES IN CELL AGINGAGING
For the first time, they mesured the damage caused by bad folding and aggregation of proteins.
NEW DISCOVERIES IN CELL NEW DISCOVERIES IN CELL AGINGAGING
The expression of Alzheimer’s AB42 peptide in bacteria, induces protein aggregation.
COMMENTCOMMENT
I think that is important to know more about proteins and their behavior because they are involved in a lot of natural processes and diseases.
PATTERNS OF CHROMOSME
ABNORMALITY: THE KEY TO CANCER?
PATTERNS OF CHROMOSME
ABNORMALITY: THE KEY TO CANCER?
Many chromosomal pairs are lost or gained together across different cancer types.
As cancer advances the genome becomes more mutated.
PATTERNS OF CHROMOSME
ABNORMALITY: THE KEY TO CANCER?
The researchers could confirm the chromosomal aberrations that are seen in specific cancer types.
PATTERNS OF CHROMOSME
ABNORMALITY: THE KEY TO CANCER?The possibility to answer the
question about cancer’s changes, can help us to understand the characteristics of its progress.
COMMENTCOMMENT
These discoveries are very important to understand better cancer in order to find how to make it less lethal.

MEDICAL UTILITYMEDICAL UTILITYEach little thing about the human
being is so complex and so well done, that is very difficult to clear up all the mysteries that it keeps.
MEDICAL UTILITYMEDICAL UTILITY
With all the knowledge about this, it will be easier to prevent and even to cure a lot of acute, chronic or lethal diseases.
MEDICAL UTILITYMEDICAL UTILITYAs we learn more about these
chromosomal aberrations, we get to be able to give a better life to people that have genetic chromosomal aberrations or cancer.
