The NEDD8 activating enzyme inhibitor MLN4924 mitigates doxorubicin-induced cardiotoxicity in mice.

Doxorubicin (DOX) is a widely utilized chemotherapeutic agent in clinical oncology for treating various cancers. However, its clinical use is constrained by its significant side effects. Among these, the development of cardiomyopathy, characterized by cardiac remodeling and eventual heart failure, stands as a major concern following DOX chemotherapy.

MRI delineation of the morphometric characteristics of type I split cord malformations: a retrospective analysis of 29 cases.

Objective: The purpose of this study was to elucidate the morphometric characteristics by magnetic resonance imaging (MRI) of type I split cord malformation (SCM) patients.

Methods: All subjects received conventional MRI with the Achieva 3.0T system (Philips Healthcare, Andover, MA, USA), including T1WI/axial and sagittal T2WI/axial FLAIR.

Gene therapy with lipopolysaccharide binding protein for gram-negative pneumonia: respiratory physiology.

Background: Lipopolysaccharide binding protein (LBP) plays an essential role in the pulmonary immune response to gram-negative bacterial infection. LBP knockout mice with gram-negative pneumonia have increased mortality compared with wild-type controls. This mortality difference can be abolished with systemic LBP gene therapy.

Improved survival in mice given systemic gene therapy in a gram negative pneumonia model.

Background: We previously demonstrated an essential role for lipopolysaccharide binding protein (LBP) in the pulmonary immune response to Gram-negative bacterial infection. LBP knockout mice had significantly higher mortality, greater rates of bacteremia, and higher counts of viable bacteria in their lungs at sacrifice compared with wild-type controls. We postulate that systemic LBP gene therapy will reconstitute a protective innate immune response in LBP knockout mice and that overexpression of LBP in wild-type mice may offer a survival advantage.

Lipopolysaccharide-binding protein modulates acetaminophen-induced liver injury in mice.

Acetaminophen toxicity is the most common cause of acute liver failure in the United States and Europe. Although much is known about the metabolism of acetaminophen, many questions remain regarding the pathogenesis of liver injury. In this study, we examined the role of lipopolysaccharide-binding protein (LBP), a protein important in mediating cellular response to lipopolysaccharides, by using LBP wild-type and knockout (KO) mice.

Identification of a direct Dlx homeodomain target in the developing mouse forebrain and retina by optimization of chromatin immunoprecipitation.

Understanding homeobox gene specificity and function has been hampered by the lack of proven direct transcriptional targets during development. Dlx genes are expressed in the developing forebrain, retina, craniofacial structures and limbs. Dlx1/Dlx2 double knockout mice die at birth with multiple defects including abnormal forebrain development and decreased Dlx5 and Dlx6 expression.
