A new study shows that cancer stem cells switch from metabolizing sugar to metabolizing protein. Clinical trial based on this observation may revolutionize care for older adults with acute myeloid leukemia....
Autism has been associated with zinc deficiency in infancy. While it is not yet known whether zinc deficiency in early development causes autism, scientists have now found a mechanistic link. Their study connects zinc, autism risk genes and abnormal neuronal connections associated with autism spectrum disorders....
For the first time, scientists have created, from scratch, self-assembling protein filaments built from identical protein subunits that snap together spontaneously to form long, helical, thread-like configurations. Protein filaments are essential components of several structural and moving parts in living cells, as well as many body tissues. Being able to design and build protein filaments could allow for engineering novel materials for nano-electronics or scaffolds for new diagnostic tests....
A recent pilot study by kinesiologists found that pedaling while conducting work tasks improved insulin responses to a test meal. Investigators found that insulin levels following the meal were lower when sedentary workers used a pedal desk compared to a standard desk. In addition, work skills were not decreased in the pedaling condition....
Scientists have shown how thalidomide analogs mediate degradation of many more proteins than previously anticipated. These proteins -- zinc finger transcription factors -- play a role in cancer and developmental diseases but are difficult drug targets. The new study suggests that thalidomide analogs can be rationally designed to target this challenging class of proteins....
A clinical trial has shown eating fish such as salmon, trout and sardines as part of a healthy diet can reduce asthma symptoms in children....
