Altered RNA processing is an underlying mechanism of amyotrophic lateral sclerosis (ALS). Missense mutations in a number of genes involved in RNA function and metabolisms are associated with ALS. Among these genes is angiogenin (ANG), the fifth member of the vertebrate-specific, secreted ribonuclease superfamily. ANG is an angiogenic ribonuclease, and ...

In a previous meta-analysis across almost 200 neuroimaging experiments, working memory for object location showed significantly stronger convergence on the posterior superior frontal gyrus, whereas working memory for identity showed stronger convergence on the posterior inferior frontal gyrus (dorsal to, but overlapping with Brodmann's area BA 44). As similar locations ...

Dihydroorotate dehydrogenase (DHODH) is an important drug target due to its prominent role in pyrimidine biosynthesis. Leflunomide and brequinar are two well-known DHODH inhibitors, which bind to the enzyme in the same pocket with different binding modes. We have recently realized a series of new inhibitors based on the 4-hydroxy-1,2,5-oxadiazole ...

It is well established that chromosomes occupy distinct positions within the interphase nuclei, conferring a potential functional implication to the genome. In addition, alterations in the nuclear organisation patterns have been associated with disease phenotypes (e.g. cancer or laminopathies). The human sperm is the smallest cell in the body with ...

BACKGROUND: Breast cancer patients regularly undergo adjuvant chemotherapies following surgery. However, these treatments are largely associated with chemotherapeutic toxicities ranging from nausea to severe myelosuppression. In this investigation, we examined the effects of four SNPs in NR1I2, CYP3A4 and CYP3A5 genes on chemotherapy-induced severe neutropenia in 311 female Chinese breast ...

Many fungi have significant industrial applications or biosafety concerns and maintaining the original characteristics is essential. The preserved fungi have to represent the situation in nature for posterity, biodiversity estimations, and taxonomic research. However, spontaneous fungal mutations and secondary metabolites affecting producing fungi are well known. There is increasing interest ...

Major Histocompatibility Complex (MHC) class II deficiency is a combined primary immunodeficiency disease that leads to overwhelming and recurrent infections. It was found to account for 19 % of combined immune deficiency cases in the National Primary Immunodeficiency Disorders Registry in Kuwait, a country with high prevalence of consanguinity.
