P-glycoprotein multidrug transporter in inflammatory bowel diseases: More questions than answers

引用

World Journal of Gastroenterology 2017年第9期23卷 1513-1520页

作者： elke Cario Experimental Gastroenterology Department of Gastroenterology and HepatologyUniversity Hospital EssenMedical SchoolUniversity of Duisburg-Essen45147 EssenGermany

The gastrointestinal barrier is constantly exposed to numerous environmental substrates that are foreign and potentially harmful. These xenobiotics can cause shifts in the intestinal microbiota composition, affect mucosal immune responses, disturb tissue integrity and impair regeneration. The multidrug transporter ABCB1/MDR1 p-glycoprotein (p-gp) plays a key role at the front line of host defence by efficiently protecting the gastrointestinal barrier from xenobiotic accumulation. This Editorial discusses how altered expression and function of ABCB1/MDR1 p-gp may contribute to the development and persistence of chronic intestinal inflammation in inflammatory bowel diseases (IBD). Recent evidence implies multiple interactions between intestinal microbiota, innate immunity and xenobiotic metabolism via p-gp. While decreased efflux activity may promote disease susceptibility and drug toxicity, increased efflux activity may confer resistance to therapeutic drugs in IBD. Mice deficient in MDR1 A develop spontaneously chronic colitis, providing a highly valuable murine IBD model for the study of intestinal epithelial barrier function, immunoregulation, infectious co-triggers and novel therapeutic approaches. Possible associations of human ABCB1 gene polymorphisms with IBD susceptibility have been evaluated, but results are inconsistent. Future studies must focus on further elucidation of the pathophysiological relevance and immunological functions of p-gp and how its ambiguous effects could be therapeutically targeted in IBD.

Correlation of Lopingian to Middle Triassic Palynozones

Terrestrial floras underwent important changes during the Lopingian （Late Permian）, Early Triassic, and Middle Triassic, i.e., before, during, and after the end-Permian mass extinction. An accurate account of these developments requires reliable correlation. Macrofossils of land plants can only provide a low-resolution biostratigraphy, while detailed zonation schemes based on palynomorphs are available for many regions. Their applicability is still limited due to several factors, such as （micro-）floral provincialism, a lack of suitable marker taxa commonly occurring at important boundaries, and in many cases a lack of independent age control. Nevertheless, these palynostratigraphic schemes are regularly used for dating and correlation of successions between different regions. To support such efforts, the biozonation schemes based on palynomorphs from the Lopingian up to and including the Middle Triassic from across the world are summarized and revised. Thus, a consistent correlation of palynozones with the currently recognized international stages is established.

Orotic Acid, More Than Just an Intermediate of Pyrimidine de novo Synthesis

引用

Journal of Genetics and Genomics 2015年第5期42卷 207-219页

作者： Monika L?ffler Elizabeth A.Carrey elke Zameitat Institute of Physiological Chemistry Faculty of Medicine Philipps University Marburg UCL Institute of Child Health University College London

It is timely to consider the many facets of the small molecule orotic acid （OA）, which is well-known as an essential intermediate of pyrimidine de novo synthesis. In addition, it can be taken up by erythrocytes and hepatocytes for conversion into uridine and for use in the pyrimidine recycling pathway. We discuss the link between dietary orotate and fatty liver in rats, and the potential for the alleviation of neonatal hyperbilirubinaemia. We address the development of orotate derivatives for application as anti-pyrimidine drugs, and of com- plexes with metal ions and organic cations to assist therapies of metabolic syndromes. Recent genetic data link human Miller syndrome to defects in the dihydroorotate dehydrogenase （DHODH） gene, hence to depleted orotate production. Another defect in pyrimidine biosynthesis, the orotic aciduria arising in humans and cattle with a deficiency of UMP synthase （UMPS）, has different symptoms. More recent work leads us to conclude that OA may have a role in regulating gene transcription.
