The Hu RNA-binding protein family consists of four members: HuR/A, HuB, HuC and HuD. HuR expression is widespread. The other three neuron-specific Hu proteins play an important role in neuronal differentiation through modulating multiple processes of RNA metabolism. In the splicing events examined previously, Hu proteins promote skipping of the alternative exons. Here, we report the first examp...

Sickle cell anemia (SCA) is a recessively inherited disease characterized by chronic hemolytic anemia, chronic inflammation, and acute episodes of hemolysis. Hydroxyurea (HU) is widely used to increase the levels of fetal hemoglobin (HbF). The objective of this study was to standardize and validate a method for the quantification of HU in human plasma by using ultra high performance liquid chro...

Hydroxyurea (HU) preferentially inhibited deoxyribonucleic acid (DNA) replication and division in Saccharomyces cerevisiae. Growth, ribonucleic acid synthesis, and protein synthesis were less sensitive to this drug. Upon addition of HU, cells underwent one cycle of budding and the nuclei migrated into the necks between the mother cells and buds. Neither the nucleus nor the cells divided. Remova...

The rodent hindlimb unloading (HU) model was developed in the 1980s to make it possible to study mechanisms, responses, and treatments for the adverse consequences of spaceflight. Decades before development of the HU model, weightlessness was predicted to yield deficits in the principal tissues responsible for structure and movement on Earth, primarily muscle and bone. Indeed, results from earl...

This study aimed to evaluate testicular toxicity induced by hydroxyurea (HU) and the possible counteracting effect of an aqueous extract of Cistanche deserticola (CD). HU is an antineoplastic drug that has potential reproductive toxicity, and Herba Cistanche has been used as a tonic for the reproductive system for thousands of years. Sixty mice were randomly divided into five groups. Except mic...
