To understand the evolution of human mental activity, we performed population genetic analyses of nucleotide sequences ( approximately 11 kb) from a worldwide sample of 60 chromosomes of the N-acylsphingosine amidohydrolase (ASAH1) gene. ASAH1 hydrolyzes ceramides and regulates neuronal development, and its deficiency often results in mental retardation. In the region ( approximately 4.4 kb) en...
Glioblastoma multiforme (GBM) is the most common primary, intracranial malignancy of the central nervous system. The standard treatment protocol, which involves surgical resection, and concurrent radiation with adjuvant temozolomide (TMZ), still imparts a grim prognosis. Ultimately, all GBMs exhibit recurrence or progression, developing resistance to standard treatment. This study demonstrates ...
Glioblastoma remains the most common, malignant primary cancer of the central nervous system with a low life expectancy and an overall survival of less than 1.5 years. The treatment options are limited and there is no cure. Moreover, almost all patients develop recurrent tumors, which typically are more aggressive. Therapeutically resistant glioblastoma or glioblastoma stem-like cells (GSCs) ar...
Farber disease (FD) is a severe inherited disorder of lipid metabolism characterized by deficient lysosomal acid ceramidase (ACDase) activity, resulting in ceramide accumulation. Ceramide and metabolites have roles in cell apoptosis and proliferation. We introduced a single-nucleotide mutation identified in human FD patients into the murine Asah1 gene to generate the first model of systemic ACD...
farber lipogranulomatosis is a rare inherited condition involving the breakdown and use of fats in the body (lipid metabolism). characteristics are early-onset subcutaneous nodules, painful and progressively deformed joints, and hoarseness by laryngeal involvement in affected individuals, lipids accumulate abnormally in cells and tissues throughout the body, particularly around the joints. thre...
Acid ceramidase (AC) catalyzes the hydrolysis of ceramide into sphingosine, in turn a substrate of sphingosine kinases that catalyze its conversion into the mitogenic sphingosine-1-phosphate. AC is expressed at high levels in several tumor types and has been proposed as a cancer therapeutic target. Using a model derived from PC-3 prostate cancer cells, the highly tumorigenic, metastatic, and ch...
Background and aims: Phthalates, which are commonly used to render plastics into soft and flexible materials, have also determined as developmental and reproductive toxicants in human and animals. The purpose of this study was to evaluate the effect of mono-(2-ethylhexyl) phthalate (MEHP) and di-(2-ethylhexyl) phthalate (DEHP) oral administration on maturation of mouse oocytes, apoptosis and ge...
Better prognostic and predictive markers in melanoma are needed to select patients for therapy. We utilized a dual-lectin affinity chromatography and a natural protein microarray-based analysis to select a subproteome of target glycoproteins to profile serum antibodies against melanoma associated antigens that may predict nodal positivity. We identified 5 melanoma-associated antigens using this...
