B-cell chronic lymphocytic leukemia (CLL) is a common type of cancer where a specific type of white blood cell (called B cells or B lymphocytes) grows out of control. It's characterized by the presence, on the leukemic cells, of a protein called CD5. The disease is quite challenging to treat, and we still don't fully understand why it develops or how it progresses. This project aimed to uncover part of the mysteries behind the role of a key protein called the B-cell receptor (BCR) in CLL. A better understanding of how the BCR works in this disease could lead to new treatments.
Current therapies offer some relief and extend the lives of patients with CLL, but they also come with side effects, unintended effects, and the problem of tumors becoming resistant to treatment. Moreover, since these treatments don't provide a complete cure, they also put a heavy burden on healthcare systems worldwide. Thus, a better understanding of the cellular mechanisms involved in CLL will allows for the development of novel, more potent therapies, directly benefit patients by reducing side effects and prolonging remission periods, and indirectly by easing the financial strain on healthcare systems.
The goal of the project included the identification of several features implicated with the key protein of the CLL leukemic cells, the BCR, the link of these feature with the various ways a CLL cell can uncontrollably grow in response to agents present in our bodies, and the identification of genes involved in this process that could be potentially exploited for the development of novel therapies. Concomitantly, to carry this goal out, the project aimed to develop a machine learning algorithm that could help to identify non-obvious relationships among the different clinical and biological features evaluated.
