Sphingolipids
A class of membrane lipids that have a polar head and two nonpolar tails. They are composed of one molecule of the long-chain amino alcohol sphingosine (4-sphingenine) or one of its derivatives, one molecule of a long-chain acid, a polar head alcohol and sometimes phosphoric acid in diester linkage at the polar head group. (Lehninger et al, Principles of Biochemistry, 2nd ed)
Epidermis

Bone Marrow Neoplasms
Sarcoma, Ewing
Bone Marrow
The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
Ifosfamide
Etoposide
A semisynthetic derivative of PODOPHYLLOTOXIN that exhibits antitumor activity. Etoposide inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This complex induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent entry into the mitotic phase of cell division, and lead to cell death. Etoposide acts primarily in the G2 and S phases of the cell cycle.

Multigene Family
A set of genes descended by duplication and variation from some ancestral gene. Such genes may be clustered together on the same chromosome or dispersed on different chromosomes. Examples of multigene families include those that encode the hemoglobins, immunoglobulins, histocompatibility antigens, actins, tubulins, keratins, collagens, heat shock proteins, salivary glue proteins, chorion proteins, cuticle proteins, yolk proteins, and phaseolins, as well as histones, ribosomal RNA, and transfer RNA genes. The latter three are examples of reiterated genes, where hundreds of identical genes are present in a tandem array. (King & Stanfield, A Dictionary of Genetics, 4th ed)

Specific and sensitive assay for alkaline and neutral ceramidases involving C12-NBD-ceramide. (1/19)
A fluorescent analogue of ceramide, C12-NBD-ceramide, was found to be hydrolyzed much faster than 14C-labeled ceramide by alkaline ceramidase from Pseudomonas aeruginosa and neutral ceramidase from mouse liver, while this substrate was relatively resistant to acid ceramidase from plasma of the horseshoe crab. The radioactive substrate was used more preferentially by the acid ceramidase. It should be noted that C6-NBD-ceramide, which is usually used for ceramidase assays, was hardly hydrolyzed by any of the enzymes examined, compared to C12-NBD-ceramide. For the alkaline and neutral enzymes, the Vmax and k (Vmax/Km) with C12-NBD-ceramide were much higher than those with 14C-ceramide. In contrast, for the acid enzyme these parameters with C12-NBD-ceramide were less than half those with the radioisotope-labeled substrate. It is noteworthy that the labeling of ceramide with NBD did not itself reduce the Km of the alkaline enzyme, but did that of the neutral enzyme. It was also found that C12-NBD-ceramide was preferentially hydrolyzed by the alkaline and neutral enzymes, but not the acid one, in several mammalian cell lines. This study clearly shows that the attachment of NBD, but not dansyl, increases the susceptibility of ceramide to alkaline and neutral enzyme, and decreases that to acid enzymes. Thus the use of this substrate provides a specific and sensitive assay for alkaline and neutral ceramidases. (+info)Molecular cloning, sequencing, and expression of the gene encoding alkaline ceramidase from Pseudomonas aeruginosa. Cloning of a ceramidase homologue from Mycobacterium tuberculosis. (2/19)
We previously reported the purification and characterization of a novel type of alkaline ceramidase from Pseudomonas aeruginosa strain AN17 (Okino, N., Tani, M., Imayama, S., and Ito, M. (1998) J. Biol. Chem. 273, 14368-14373). Here, we report the molecular cloning, sequencing, and expression of the gene encoding the ceramidase of this strain. Specific oligonucleotide primers were synthesized using the peptide sequences of the purified ceramidase obtained by digestion with lysylendopeptidase and used for polymerase chain reaction. DNA fragments thus amplified were used as probes to clone the gene encoding the ceramidase from a genomic library of strain AN17. The open reading frame of 2,010 nucleotides encoded a polypeptide of 670 amino acids including a signal sequence of 24 residues, 64 residues of which matched the amino acid sequence determined for the purified enzyme. The molecular weight of the mature enzyme was estimated to be 70,767 from the deduced amino acid sequence. Expression of the ceramidase gene in Escherichia coli, resulted in production of a soluble enzyme with the identical N-terminal amino acid sequence. Recombinant ceramidase was purified to homogeneity from the lysate of E. coli cells and confirmed to be identical to the Pseudomonas enzyme in its specificity and other enzymatic properties. No significant sequence similarities were found in other known functional proteins including human acid ceramidase. However, we found a sequence homologous to the ceramidase in hypothetical proteins encoded in Mycobacterium tuberculosis, Dictyostelium discoideum, and Arabidopsis thaliana. The homologue of the ceramidase gene was thus cloned from an M. tuberculosis cosmid and expressed in E. coli, and the gene was demonstrated to encode an alkaline ceramidase. This is the first report for the cloning of an alkaline ceramidase. (+info)Purification and characterization of a neutral ceramidase from mouse liver. A single protein catalyzes the reversible reaction in which ceramide is both hydrolyzed and synthesized. (3/19)
We report here a novel ceramidase that was purified more than 150, 000-fold from the membrane fraction of mouse liver. The enzyme was a monomeric polypeptide having a molecular mass of 94 kDa and was highly glycosylated with N-glycans. The amino acid sequence of a fragment obtained from the purified enzyme was homologous to those deduced from the genes encoding an alkaline ceramidase of Pseudomonas aeruginosa and a hypotheical protein of the slime mold Dictyostelium discoideum. However, no significant sequence similarities were found in other known functional proteins including acid ceramidases of humans and mice. The enzyme hydrolyzed various N-acylsphingosines but not galactosylceramide, sulfatide, GM1a, or sphingomyelin. The enzyme exhibited the highest activity around pH 7.5 and was thus identified as a type of neutral ceramidase. The apparent K(m) and V(max) values for C12-4-nitrobenzo-2-oxa-1, 3-diazole-ceramide and C16-(14)C-ceramide were 22.3 microM and 29.1 micromol/min/mg and 72.4 microM and 3.6 micromol/min/mg, respectively. This study also clearly demonstrated that the purified 94-kDa ceramidase catalyzed the condensation of fatty acid to sphingosine to generate ceramide, but did not catalyze acyl-CoA-dependent acyl-transfer reaction. (+info)Cloning and characterization of a novel human alkaline ceramidase. A mammalian enzyme that hydrolyzes phytoceramide. (4/19)
Ceramidases are enzymes involved in regulating cellular levels of ceramides, sphingoid bases, and their phosphates. Based on sequence homology to the yeast alkaline ceramidases YPC1p (Mao, C., Xu, R., Bielawska, A., and Obeid, L. M. (2000) J. Biol. Chem. 275, 6876--6884) and YDC1p (Mao, C., Xu, R., Bielawska, A., Szulc, Z. M., and Obeid, L. M. (2000) J. Biol Chem. 275, 31369--31378), we report the identification and cloning of a cDNA encoding for a novel human alkaline ceramidase (aPHC) that hydrolyzes phytoceramide selectively. Northern blot analysis showed that aPHC was ubiquitously expressed, with the highest expression in placenta. Green fluorescent protein tagging showed that it was localized in both the Golgi apparatus and endoplasmic reticulum. Overexpression of aPHC in mammalian cells elevated in vitro ceramidase activity toward N-4-nitrobenz-2-oxa-1,3-diazole-C(12)-phytoceramide. Its expression in a yeast mutant strain devoid of any ceramidase activity restored the ceramidase activity and caused an increase in the hydrolysis of phytoceramide in yeast cells, thus leading to the decreased biosynthesis of sphingolipids. These data collectively suggest that, similar to the yeast phytoceramidase YPC1p, aPHC has phytoceramidase activity both in vitro and in cells; hence, it is a functional homolog of the yeast phytoceramidase YPC1p. However, in contrast to YPC1p, aPHC exhibited no reverse activity of ceramidase either in vitro or in cells. Biochemical characterization showed that aPHC had a pH optimum of 9.5, was activated by Ca(2+), but was inhibited by Zn(2+) and sphingosine. Substrate specificity showed that aPHC hydrolyzed phytoceramide preferentially. Together, these data demonstrate that aPHC is a novel human alkaline phytoceramidase, the first mammalian alkaline ceramidase to be identified as being specific for the hydrolysis of phytoceramide. (+info)Cloning and characterization of a mouse endoplasmic reticulum alkaline ceramidase: an enzyme that preferentially regulates metabolism of very long chain ceramides. (5/19)
Ceramidases deacylate ceramides, important intermediates in the metabolic pathway of sphingolipids. In this study, we report the cloning and characterization of a novel mouse alkaline ceramidase (maCER1) with a highly restricted substrate specificity. maCER1 consists of 287 amino acids, and it has a 28 and 32% identity to the Saccharomyces alkaline ceramidases (YPC1p and YDC1p) and the human alkaline phytoceramidase, respectively. Reverse transcriptase-PCR analysis demonstrated that maCER1 was predominantly expressed in skin. maCER1 was localized to the endoplasmic reticulum as revealed by immunocytochemistry. In vitro biochemical characterization determined that maCER1 hydrolyzed D-erythro-ceramide exclusively but not D-erythro-dihydroceramide or D-ribo-phytoceramide. Similar to other alkaline ceramidases, maCER1 had an alkaline pH optimum of 8.0, and it was activated by Ca2+ but inhibited by Zn2+,Cu2+, and Mn2+. maCER1 was also inhibited by sphingosine, one of its products. Metabolic labeling studies showed that overexpression of maCER1 caused a decrease in the incorporation of radiolabeled dihydrosphingosine into ceramide and complex sphingolipids but led to a concomitant increase in sphingosine-1-P (S1P) in HeLa cells. Mass measurement showed that overexpression of maCER1 selectively lowered the cellular levels of D-erythro-C24:1-ceramide, but not other ceramide species and caused an increase in the levels of S1P. Taken together, these data suggest that maCER1 is a novel alkaline ceramidase with a stringent substrate specificity and that maCER1 is selectively expressed in skin and may have a role in regulating the levels of bioactive lipids ceramide and S1P, as well as complex sphingolipids. (+info)Golgi alkaline ceramidase regulates cell proliferation and survival by controlling levels of sphingosine and S1P. (6/19)
Sphingosine-1-phosphate (S1P), a sphingolipid metabolite, promotes cell proliferation and survival whereas its precursor, sphingosine, has the opposite effects. However, much remains unknown about their regulation. Here we identify a novel human ceramidase (haCER2) that regulates the levels of both sphingosine and S1P by controlling the hydrolysis of ceramides. haCER2 is localized to the Golgi complex and is highly expressed in the placenta. High ectopic expression of haCER2 caused fragmentation of the Golgi complex and growth arrest in HeLa cells due to sphingosine accumulation. Low ectopic expression of haCER2 increased S1P without sphingosine accumulation, promoting cell proliferation in serum-free medium. This proliferative effect was suppressed by dimethylsphingosine, an inhibitor of the S1P formation, or by the RNA interference (RNAi) -mediated inhibition of S1P(1,) a G-protein-coupled receptor for S1P. The RNAi-mediated down-regulation of haCER2 enhanced the serum deprivation-induced growth arrest and apoptosis of HeLa cells, which was inhibited by addition of exogenous S1P. Serum deprivation up-regulated both haCER2 mRNA and activity in HeLa cells. haCER2 mRNA is also up-regulated in some tumors. Taken together, these results suggest that haCER2 is important for the generation of S1P and S1P-mediated cell proliferation and survival, but that its overexpression may cause cell growth arrest due to an accumulation of sphingosine. (+info)Upregulation of the human alkaline ceramidase 1 and acid ceramidase mediates calcium-induced differentiation of epidermal keratinocytes. (7/19)
Extracellular calcium (Ca2+(o)) potently induces the growth arrest and differentiation of human epidermal keratinocytes (HEKs). We report that Ca2+(o) markedly upregulates the human alkaline ceramidase 1 (haCER1) in HEKs; and its upregulation mediates the Ca2+(o)-induced growth arrest and differentiation of HEKs. haCER1 is the human ortholog of mouse alkaline ceramidase 1 that we previously identified. haCER1 catalyzed the hydrolysis of very long-chain ceramides to generate sphingosine (SPH). This in vitro activity required Ca2+. Ectopic expression of haCER1 in HEKs decreased the levels of D-e-C(24:1)-ceramide and D-e-C(24:0)-ceramide but elevated the levels of both SPH and its phosphate (S1P), whereas RNA interference-mediated knockdown of haCER1 caused the opposite effects on the levels of these sphingolipids in HEKs. Similar to haCER1 overexpression, Ca2+(o) increased the levels of SPH and S1P, and this was attenuated by haCER1 knockdown. haCER1 knockdown also inhibited the Ca2+(o)-induced growth arrest of HEKs and the Ca2+(o)-induced expression of keratin 1 and involucrin in HEKs. In addition, the acid ceramidase (AC) was also upregulated by Ca2+(o); and its knockdown attenuated the Ca2+(o)-induced expression of keratin 1 and involucrin in HEKs. These results strongly suggest that upregulation of haCER1 and AC mediates the Ca2+(o)-induced growth arrest and differentiation of HEKs by generating SPH and S1P.
