To understand the role of CASP9 (Caspase-9) gene products in relation to neuroblastoma disease, we have analyzed the single nucleotide polymorphisms (SNPs) associated with this gene. This can help us understand the genetic variations that can alter the function of the gene products. A total of 941
Proline synthesis plays an important role in the metabolic reprogramming that contributes to tumor progression. However, the mechanisms regulating expression of proline synthetic genes in neuroblastoma (NB) remain elusive. Herein, through integrative screening of a public dataset and amino acid
BACKGROUND
The replacement of established evidence-based cancer therapy protocols (mainstream therapy) by unevaluated complementary and alternative medicine (CAM) is a challenge in pediatric oncology. We tested the hypothesis that oral application of L-lysine and ascorbic acid (Lysin C Drink) in
Cyclin-dependent kinase-5 (CDK-5) has been shown to play important roles in neuronal development and neurogenesis. In vitro studies indicate a role of CDK-5 in phosphorylation of neurofilaments (NFs). In this study, we have chosen the human neuroblastoma cell line SHSY5Y as a model system to study
Prolyl oligopeptidase (POP) is a post-proline cleaving enzyme, which is widely distributed in various organs, with high levels in the brain. In this study, we investigated the effects of a selective POP inhibitor, 3-({4-[2-(E)-styrylphenoxy]butanoyl}-l-4-hydroxyprolyl)-thiazolidine (SUAM-14746), on
Doublecortin-like (DCL) is a microtubule-binding protein crucial for neuroblastoma (NB) cell proliferation. We have investigated whether the anti-proliferative effect of DCL knockdown is linked to reduced mitochondrial activity. We found a delay in tumor development after DCL knockdown in vivo in
Human sialidase NEU4 long (N4L) is a membrane-associated enzyme that has been shown to be localized in the outer mitochondrial membrane. A role in different cellular processes has been suggested for this enzyme, such as apoptosis, neuronal differentiation and tumorigenesis. However, the molecular
The Rho/Rho kinase signaling pathway plays an essential role in neurite retraction and cell rounding in response to G(12/13)-coupled receptor activation in neuronal cells. The Rho guanine nucleotide exchange factor involved in these processes has not been identified. To monitor the activation state
Abeta peptides are major components of the amyloid plaques that characterize Alzheimer's disease. The enzyme activities (beta- and gamma-secretases) involved in generating Abeta from amyloid precursor protein (APP) are unidentified. It has been suggested that prolylendopeptidase (PEP), an
In the mammalian brain, acetylcholinesterase (AChE) is anchored in cell membranes by a transmembrane protein PRiMA (proline-rich membrane anchor). We present evidence that at least part of the PRiMA-linked AChE is integrated in membrane microdomains called rafts. A significant proportion of
Colostrinin (CLN), a mixture of proline-rich polypeptides, has shown a stabilizing effect on cognitive function in Alzheimer's patients measured by the Alzheimer's disease Assessment Scale-cognitive (ADAS-cog) and in Instrumental Activities of Daily Living (ILDL) in recently conducted clinical
p73 is a recently cloned tumor suppressor gene that is highly homologous to p53, and the products of both possess similar functions in inhibiting cell growth and inducing apoptosis. Interestingly, the COOH-terminal region of p53 displays no significant homology with that of p73. Moreover, p73 has an
The mechanisms by which neurotensin (NT) was inactivated by differentiated neuroblastoma and HT29 cells were characterized. In both cell lines, the sites of primary cleavages of NT were Pro7-Arg8, Arg8-Arg9 and Pro10-Tyr11 bonds. The cleavage at the Pro7-Arg8 bond was totally inhibited by
Truncated apolipoprotein C-I is a post-translationally modified protein characterized by the loss of threonine and proline residues from the N-terminus of the mature peptide. The truncated peptide is involved in many physiological and pathological processes in vivo and is related to malignant
Neuroblastoma, a peripheral nervous system cancer that can be highly invasive and metastatic, accounts for 8-10% of all solid childhood tumors in children under the age of 15 years. Despite multiple clinical efforts, prognosis remains poor for this enigmatic disease. A nutrient mixture (NM)
