Protein Discovery Could Unlock The Secret To Better TB Treatment

...ch year from the disease. The top challenge for TB control in the European region is multidrug-resistant TB (MDR-TB). Eight per cent of the bacteria causing TB in patients are resistant to one or more drugs and one per cent show multidrug resistance. Left untreated, a person with infectious TB of the lungs i...

On a more practical level we need to know the distribution of invasives. Weeds are often difficult to find in dense, wet forest in Hawaii. This study has helped us...

Unchecked DNA replication drives earliest steps toward cancer

...rtunately, cells have an effective on-board damage control system, managed by the p53 gene. A protein called 53BP1, the critical role of which was reported by the same Wistar group in Nature last year, senses the DNA breaks caused by replication stress and activates the p53 pathway. That pathway shuts down t...
