A new bioinformatics tool to decipher evolutionary biology
Understanding evolution is one of the cornerstones of biology - evolution is, in fact, the sole explanation for life's diversity on our planet. Based on the evolution of proteins, researchers may explain the emergence of new species and functions through genetic changes or how enzymes with novel functions might be…

Cancer-causing virus masters cell’s replication & immortality
Viruses are notorious for taking over their host's operations and using them to their own advantage. But few human viruses make themselves quite as cozy as the Epstein-Barr virus, which can be found in an estimated 9/10 humans without causing any ill effects. That is, until this virus causes mononucleosis…

Pathways leading to beta cell division identified, may aid diabetes treatment
Pancreatic beta cells help maintain normal blood glucose levels by producing the hormone insulin -- the master regulator of energy (glucose). Impairment and the loss of beta cells interrupts insulin production, leading to type 1 and 2 diabetes.

Plasticell and Kings College London to collaborate in trials of blood platelet substitute
Over 10 million units of platelets are transfused worldwide each year in one of the most common procedures in clinical medicine. However, platelets derived from human donors can transmit infections and trigger serious immune reactions that eventually render the therapy ineffective (a condition known as alloimmune refractoriness). In addition, since…

Plasticell to produce red blood cell substitute from pluripotent stem cells
Over 90 million blood transfusions are carried out worldwide each year and alternative sources to donor-derived blood are being sought to meet rising demand. In addition there is a need to secure a safer supply of blood products, chiefly in developing countries where there is a relatively higher risk of…

Premature cell differentiation leads to disorders in pancreatic development
Neonatal diabetes mellitus (NDM), or diabetes among infants less than six months of age, is a rare form of diabetes caused by a mutation in genes crusial to the development or function of beta cells. In about half of such cases, the disease becomes permanent (PNDM). Mutations in more than…
