Scientists discuss the rigorous standards followed for proteome identification by the Human Proteome Project.

Cancer, as a disease, is a puzzle on its own and scientists across the world are looking for hints from all sides to crack it. Now, what if previous research on cancer itself acts as a hint and guides new developments? That is exactly what scientists have done using bioinformatics. By scouting previous research on circulating tumour cells, scientists have identified the molecules responsible for metastasis in cancer. This discovery, they believe, can help not only in understanding the spread of cancer, but also in identifying new drug targets against the killer disease.
