SIRT6 is a member of a highly conserved family of NAD(+)-dependent deacetylases with various roles in metabolism, stress resistance, and life span. SIRT6-deficient mice develop normally but succumb to a lethal hypoglycemia early in life; however, the mechanism underlying this hypoglycemia remained unclear. Here, we demonstrate that SIRT6 functions as a(More)
We characterized 7 highly pathogenic avian influenza A(H5N1) viruses isolated from poultry in China during 2009-2012 and found that they belong to clade 2.3.4 but do not fit within the 3 defined subclades. Antigenic drift in subtype H5N1 variants may reduce the efficacy of vaccines designed to control these viruses in poultry.
Reprogramming of cellular metabolism is a key event during tumorigenesis. Despite being known for decades (Warburg effect), the molecular mechanisms regulating this switch remained unexplored. Here, we identify SIRT6 as a tumor suppressor that regulates aerobic glycolysis in cancer cells. Importantly, loss of SIRT6 leads to tumor formation without(More)
Pigs are susceptible to infection with both human and avian influenza A viruses and are considered intermediate hosts that facilitate virus reassortment. Although H5N1 virus has spread to a wide range of avian and mammalian species, data about swine H5N1 isolates are scarce. To determine whether Asian H5N1 influenza viruses had been transmitted to pigs, a(More)
Curcumin (Cur) is a major active component of the food flavor turmeric isolated from the powdered dry rhizome of Curcuma longa Linn., which has been used in traditional Chinese medicine to ameliorate intracerebral ischemic damage and reduce brain edema. However, the effects of Cur on the disruption of the blood–brain barrier (BBB) induced by brain ischemia(More)
Nitric oxide (NO) has been shown to regulate neuronal excitability in the nervous system, but little is known as to whether NO, which is synthesized in certain neurons, also serves functional roles within NO-producing neurons themselves. We investigated this possibility by using a nitric oxide synthase (NOS)-expressing neuron, and studied the role of(More)
Nitric oxide (NO) is a radical and a gas, properties that allow NO to diffuse through membranes and potentially enable it to function as a "volume messenger." This study had two goals: first, to investigate the mechanisms by which NO functions as a modulator of neuronal excitability, and second, to compare NO effects produced by NO release from chemical NO(More)
