Project description:This series represents the gene expression study of phages DT1 and 2972 during the whole process of infection. Gene expression was measured at nine time intervals (0, 2, 7, 12, 17, 22, 27, 32, 37 minutes) during phage infection.
Project description:Splenomegaly is caused by several pathological conditions, including portal hypertension, which is most frequently caused by chronic liver disease (e.g., liver cirrhosis). The detailed mechanisms through which portal pressure induces splenomegaly and the precise pathophysiological conditions in portal hypertension-induced splenomegaly remain to be fully elucidated. We used microarrays to identify the differential gene expression underlying the portal hypertension-induced splenomegaly.

Project description:Idiopathic portal hypertension (IPH) is characterized by portal hypertension due to obstruction or stenosis of the intrahepatic peripheral portal branches. Researchers have suggested that IPH may be attributed to intrahepatic peripheral portal vein thrombosis, splenic factors, abnormal autoimmunity, and related factors, however, the etiology of IPH remains unclear. We used microarrays to identify the functions of genes expressed in blood samples from patients with IPH.
Project description:Lactococcus lactis is one of the most important bacteria in dairy fermentations, being used in the production of cheese and buttermilk. The processes are vulnerable to phage attacks, and undefined mixtures of lactococcal strains are often used to reduce the risk of bacteriophage caused fermentation failure. Other preventive measures include culture rotation to prevent phage build-up and phage monitoring. Phage diversity, rather than quantity, is the largest threat to fermentations using undefined mixed starter cultures. We have developed a method for culture independent diversity analysis of lytic bacteriophages of the 936 group, the phages most commonly found in dairies. Using, as a target, a highly variable region of the portal protein gene, we demonstrate an unprecedented diversity and the presence of new 936 phages in samples taken from cheese production. The method should be useful to the dairy industry and starter culture manufacturers in their efforts to reduce phage problems.
