Specific and sensitive assay for alkaline and neutral ceramidases involving C12-NBD-ceramide. (1/51)

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. (2/51)

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)

Overexpression of acid ceramidase protects from tumor necrosis factor-induced cell death. (3/51)

Tumor necrosis factor (TNF) signals cell death and simultaneously induces generation of ceramide. To evaluate the contribution of ceramide to TNF-dependent cell death, we generated clones of the TNF-sensitive cell line L929 that constitutively overexpress human acid ceramidase (AC). Ceramidase, in concert with sphingosine kinase, metabolizes ceramide to sphingosine-1-phosphate (SPP), an inducer of proliferation. In response to TNF, parental L929 cells display a significant increase in intracellular ceramide correlated with an "atypical apoptosis" characterized by membrane blebbing, DNA fragmentation and degradation of poly(ADP-ribose) polymerase despite a lack of caspase activity. These features are strongly reduced or absent in AC-overexpressing cells. Pharmacological suppression of AC with N-oleoylethanolamine restored the accumulation of intracellular ceramide as well as the sensitivity of the transfectants to TNF, implying that an enhanced metabolization of intracellular ceramide by AC shifts the balance between intracellular ceramide and SPP levels towards cell survival. Correspondingly, inhibition of ceramide production by acid sphingomyelinase also increased survival of TNF-treated L929 cells.  (+info)

Bcl-2 overexpression prevents apoptosis induced by ceramidase inhibitors in malignant melanoma and HaCaT keratinocytes. (4/51)

We examined the biological effects of the ceramide analogues (1S,2R)-2-N-myristoylamino-1-phenyl-1-propanol (D-e-MAPP) and (1R,2R)-2-N-myristoylamino-1-(4-nitrophenyl)-1,3-propandiol (D-NMAPPD) on human HaCaT keratinocytes and human melanoma cells. We could demonstrate that D-e-MAPP and D-NMAPPD are able to suppress acid ceramidase activity. The elevation of the endogenous level of ceramide is followed by induction of apoptosis and suppression of proliferation in HaCaT keratinocytes. Moreover, we recently identified a group of human melanoma cell populations which are heterogeneously susceptible to C2-ceramide-mediated apoptosis. Studies with these melanoma cells revealed correlation between ceramide-mediated apoptosis and D-NMAPPD-induced apoptosis, confirming the effect of this inhibitor on ceramide signaling in human melanoma cells. These findings suggest ceramidase inhibitors as a potential new therapeutical class of antiproliferative and cytostatic drugs.  (+info)

The reverse activity of human acid ceramidase. (5/51)

An overexpression system was recently developed to produce and purify recombinant, human acid ceramidase. In addition to ceramide hydrolysis, the purified enzyme was able to catalyze ceramide synthesis using [14C]lauric acid and sphingosine as substrates. Herein we report detailed characterization of this acid ceramidase-associated "reverse activity" and provide evidence that this reaction occurs in situ as well as in vitro. The pH optimum of the reverse reaction was approximately 5.5, as compared with approximately 4.5 for the hydrolysis reaction. Non-ionic detergents and zinc cations inhibited the activity, whereas most other cations were stimulatory. Of note, sphingomyelin also was very inhibitory toward this reaction, whereas the anionic lipids, phosphatidic acid and phosphatidylserine, were stimulatory. Of various sphingosine stereoisomers tested in the reverse reaction, only the natural, D-erythro form could efficiently serve as a substrate. Using D-erythro-sphingosine and lauric acid as substrates, the reaction followed normal Michaelis-Menten kinetics. The Km and Vmax values toward sphingosine were 23.75 microM and 208.3 pmol/microg/h, respectively, whereas for lauric acid they were 73.76 microM and 232.5 pmol/microg/h, respectively. Importantly, the reverse activity was reduced in cell lysates from a Farber disease patient to the same extent as the acid ceramidase activity. Furthermore, when 12-(N-methyl-N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)) (NBD)-conjugated lauric acid and sphingosine were added to cultured lymphoblasts from a Farber disease patient in the presence of fumonisin B (1), the conversion to NBD-ceramide was reduced approximately 30% when compared with normal cells. These data provide important new information on human acid ceramidase and further document its central role in sphingolipid metabolism.  (+info)

Stress-induced apoptosis is impaired in cells with a lysosomal targeting defect but is not affected in cells synthesizing a catalytically inactive cathepsin D. (6/51)

The role of cathepsin D in stress-induced cell death has been investigated by using ovine fibroblasts exhibiting a missense mutation in the active site of cathepsin D. The cathepsin D (lysosomal aspartic protease) deficiency did not protect cells against toxicity induced by doxorubicin and other cytotoxic agents, neither did it protect cells from caspase activation. Moreover, the cathepsin D inhibitor, pepstatin A, did not prevent stress-induced cell death in human fibroblasts or lymphoblasts. The possible role of lysosomal ceramide or sphingosine-mediated activation of cathepsin D in apoptosis was also excluded by using human cells either overexpressing or deficient in acid ceramidase. However, a normal lysosomal function seems to be required for efficient cell death, as indicated by the finding that fibroblasts from patients with mucolipidosis II were partially resistant to staurosporine, sphingosine and TNF-induced apoptosis, suggesting a key role of lysosomes in cell death.  (+info)

Upregulation of the human alkaline ceramidase 1 and acid ceramidase mediates calcium-induced differentiation of epidermal keratinocytes. (7/51)

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.  (+info)

Glioblastoma is considered as the most aggressive form of brain tumor with overall survival less than fifteen months after diagnosis, even with multimodal therapy. It constitutes a major percentage of malignant brain tumors, with over 10,000 new cases reported every year in the USA. Comprehensive proteomic study of the disease in our lab has revealed that acid ceramidase is a novel target for possible drug development. Previous in Vitro study has found that acid ceramidase inhibitors (e.g. carmofur) have better efficacy than the standard chemotherapeutic drug available. This study aims to identify the role of acid ceramidase in glioblastoma and the efficacy of acid ceramidase inhibitors in suppressing the tumor, which may potentially lead to the development of a new chemotherapeutic agent for treating glioblastoma. Herein, we have worked towards the development of xenografted zebrafish (Danio rerio) glioblastoma model. For which, we have developed a zebrafish experimental microinjection protocol, where

Cellular senescence is linked to chronic age-related diseases including atherosclerosis, diabetes, and neurodegeneration. Compared to proliferating cells, senescent cells express distinct subsets of proteins. In this study, we used cultured human diploid fibroblasts rendered senescent through replicative exhaustion or ionizing radiation to identify proteins differentially expressed during senescence. We identified acid ceramidase (ASAH1), a lysosomal enzyme that cleaves ceramide into sphingosine and fatty acid, as being highly elevated in senescent cells. This increase in ASAH1 levels in senescent cells was associated with a rise in the levels of ASAH1 mRNA and a robust increase in ASAH1 protein stability. Furthermore, silencing ASAH1 in pre-senescent fibroblasts decreased the levels of senescence proteins p16, p21, and p53, and reduced the activity of the senescence-associated β-galactosidase. Interestingly, depletion of ASAH1 in pre-senescent cells sensitized these cells to the senolytics

Sucrose non-fermenting protein (SNF1)-related kinase (SNRK) is a homologue of the yeast Snf1 kinase, mutants of which fail to thrive when provided with non-fermentable carbon sources. In the mouse lung SNRK expression is specific to capillary endothelial cells [63]. SNRK is phosphorylated and activated by the LKB1 serine/threonine-protein kinase that regulates cell polarity and functions also as a tumor suppressor [64]. In view of the vascular abnormalities found in LKB1 null mice LKB1 has been placed in the VEGF signalling pathway [65]. Together, these lines of evidence suggest that SNRK is also in the VEGF signalling pathway.. Monoamine oxidase A (MAOA) degrades amine neurotransmitters including serotonin. MAOA is located on the X chromosome and its upregulation in IPAH suggests a possible involvement in the development IPAH given the female prederiliction of the disease..

FUNCTION: This gene encodes acid ceramidase, an enzyme that plays a central role in ceramide metabolism. The encoded protein undergoes proteolytic processing to generate a heterodimeric enzyme comprised of alpha and beta subunits that catalyzes the hydrolysis of sphingolipid ceramide into sphingosine and free fatty acid. The homozygous disruption of this gene leads to embryonic lethality in mice whereas the heterozygous animals exhibit a progressive lipid storage disease phenotype. [provided by RefSeq, Oct 2015 ...
Carmofur (INN) or HCFU (1-hexylcarbamoyl-5-fluorouracil) is a pyrimidine analogue used as an antineoplastic agent. It is a derivative of fluorouracil, being a lypophilic-masked analog of 5-FU that can be administered orally. Carmofur prodrug is ingested and taken up in the intestine, overcoming the problem of 5-FU degradation by dihydropyrimidine dehydrogenase. Once inside a cell, carmofur prodrug is converted into 5-FU. The mechanism of action of carmofur prodrug is traditionally thought to be the generation of 5-FU. However, carmofur is a highly potent acid ceramidase (AC) inhibitor. Ceramide influences cancer cell survival, growth and death. Inhibition of AC activity sensitizes tumor cells to the effects of antineoplastic agents and radiation. Product marketing for carmofur started in 1981. Carmofur has also been used as adjuvant chemotherapy for curatively resected colorectal cancer patients in China, Japan, and Finland for many years. Trials and meta-analyses have confirmed that the drug is ...

An authentic small animal model of Farber disease would greatly facilitate research into disease mechanisms and aid in the development of effective therapies. Unfortunately, a complete knock‐out model of Farber disease resulted in early embryonic lethality (Li et al, 2002) and a reduction of ACDase activity in the ovaries of a conditional knock‐out resulted in oocyte apoptosis (Eliyahu et al, 2012). These data highlight the difficulty in generating mouse models of certain LSDs, in particular the lipid storage disorders. These data also suggest that normal ceramide levels and metabolism are critical for early embryonic development.. Significant progress has been made towards effective therapies for LSDs through the use of recombinant enzyme replacement, bone marrow transplantation (BMT), small molecule drugs and gene therapy. It is likely that Farber disease would be responsive to similar approaches. However, the lack of an authentic animal model of Farber disease has hindered this ...
Conclusions A significant percentage of moderate Farber Disease patients are likely diagnosed as having JIA. Given this finding, it is important to increase awareness of Farber Disease in the pediatric rheumatology community. Differential diagnosis can be made by accounting for the comparatively early onset, progressive symmetric arthritis, presence of subcutaneous nodules at the joints, scalp and/or spine, and an unusual, hoarse cry or voice (due to nodule formation on the larynx) in FD patients. Based on experience with bone marrow transplantation in Farber Disease2, enzyme replacement therapy could resolve or significantly attenuate the arthritis phenotype in patients. Such therapy is currently under development. We propose that Farber Disease can account for specific cases diagnosed as JIA, and that clinically guided genetic screening of the JIA population will reveal patients who can benefit from disease-specific care and treatment.. ...
Farber disease (also known as Farbers lipogranulomatosis, ceramidase deficiency, Fibrocytic dysmucopolysaccharidosis, and Lipogranulomatosis[1]:545) is an extremely rare (80 cases reported worldwide to this day[2]) autosomal recessive lysosomal storage disease marked by a deficiency in the enzyme ceramidase that causes an accumulation of fatty material sphingolipids leading to abnormalities in the joints, liver, throat, tissues and central nervous system. Normally, the enzyme ceramidase breaks down fatty material in the bodys cells. In Farber Disease, the gene responsible for making this enzyme is mutated. Hence, the fatty material is never broken down and, instead, accumulates in various parts of the body, leading to the signs and symptoms of this disorder. ...

Introduction. In this study, we evaluated the anticancer activity of DM102 [(2R,3Z)-N-(1-hydroxyoctadec-3-en-2-yl)pivalamide], a novel inhibitor of the enzyme acid ceramidase (AC), a key regulator of ceramide metabolism, in combination with C6-ceramide (C6-cer) in human breast cancer cells. Ceramide, a bioactive sphingolipid and potent enhancer of apoptosis, is known to play a role in chemo- and radiation-induced cell death. AC tempers ceramide-induced apoptosis by hydrolysis, producing sphingosine and free fatty acid, thus reducing intracellular ceramide levels and providing substrate for sphingosine kinase, which converts sphingosine to sphingosine 1-phosphate. AC has emerged as a putative anticancer target following reports of upregulation in prostate cancer and in some breast tumors. In the present work, we determined whether the introduction of an AC inhibitor would enhance the apoptosis-inducing effects of C6-cer in breast cancer cells.. Methods. Cultured breast cancer cells were ...
Sidney Farber (September 30, 1903 - March 30, 1973) was an American pediatric pathologist. He is regarded as the father of modern chemotherapy, and the Dana-Farber Cancer Institute is named after him. He was born in Buffalo, New York to Jewish parents Simon and Matilda (Goldstein) Farber. He was the third oldest of 14 siblings. He was the younger brother of the noted philosopher and University of Buffalo professor Marvin Farber (1901-1980). Sidney Farber graduated from SUNY Buffalo in 1923. In the mid-1920s, Jewish students were often refused admission to US medical schools, prompting him to go to Europe. As Farber was fluent in German, he undertook his first year of medical school at the Universities of Heidelberg and Freiburg in Germany. Having excelled in Germany, Farber entered Harvard Medical School as a second-year student and graduated in 1927. After graduate training in pathology at Peter Bent Brigham Hospital (the predecessor of Brigham and Womens Hospital) in Boston, Massachusetts, ...

Ceramide plays an important role in regulating cell proliferation and apoptosis. Recent studies indicate that generation of ceramide in the intestine from sphingomyelin hydrolysis may be implicated in colon cancer development. The enzymes that catalyze the further hydrolysis of ceramide in the intestine have, however, not been well investigated. Our data reveal the existence of a ceramidase (EC 3.5.1.23) in rat intestinal mucosa with an optimal pH of 7.0. One milligram of mucosal protein is able to hydrolyze 44.0 ± 9.6 nmol of ceramide in 1 hr. The activity is low in the proximal duodenum and increases to a plateau in the proximal jejunum. The activity is then similar throughout the small intestine, until it declines in the distal part of ileum. Some activity is also detectable in the colon. The activity increases slightly in the presence of monomeric bile salt concentrations and sharply at the critical micellar concentration. Similar patterns were observed for both primary (taurocholate) and ...

Farber would eventually be defeated by the Shepherds.
In June 3, 1948, The New England Journal of Medicine published a study by Sidney Farber, MD, showing that a synthetic compound, 4-aminopteroylglutamic acid (aminopterin), could induce remissions in seriously ill children with acute leukemia.1 Although the study was small-just 16 children-10 showed clinical, hematologic, and pathologic evidence of improvement. Even though the childrens remissions were short-lived, Dr. Farbers findings were so groundbreaking-until then, no drug had proved effective against non-solid tumor cancers-they ushered in the era of chemotherapeutics, chemical agents that could stop cancer cells from growing and replicating, in effect killing them.. Aminopterin was later replaced by methotrexate, a similar but more effective folic acid antagonist with fewer side effects, which is still used today in the treatment of leukemia and other blood and solid tumor cancers. Nevertheless, the results of Dr. Farbers study earned him the title, the Father of Modern ...

Temporary restorations often look almost as good as the final restoration. We want the patients to look at the temporary and say, Wow! This looks great and feels great. The final restoration will be better. but we need to work this all out in the temporary stage. Because temporary restorations look so good, patients sometimes delay getting a final crown or final bridge on their implants. The problem with that scenario is that bacteria can leak under the temporary restoration and that may affect the health of the implant in the long run. There is a set amount of time that a temporary restoration is designed to last, and people should not go beyond that timeframe. Typically six months is the longest amount of time that I would recommend that a patient keep a temporary restoration. They need to return to the office in a timely manner and get their new, permanent teeth.. Dr. Alan H. Farber. Periodontist. Offices in Hauppauge and Medford, NY.

When David Hahns daughter was in high school, she had to complete an oral-history project on someone with an extraordinary life story.. For Hahn, one person immediately came to mind: Erich Farber.. He has a story that you really wont find from anyone else, said Hahn, chair of the Department of Mechanical and Aerospace Engineering at the University of Florida. He was truly remarkable.. Farber, who became a faculty member in the department in 1954 and eventually served as director of UFs Solar Energy and Energy Conversion Laboratory, passed away on April 9. He was 95.. He was a world-renowned expert, cutting-edge researcher and 36-year professor in solar-energy technologies. In addition, he earned military decorations in World War II and served as a mountain-climbing instructor and Boy Scout leader.. My dad had the ability to do just about anything, said his son, Webb Farber, and he did.. Erich Farber was passionate about researching and developing solar-energy technologies at a time ...

Volunteer Name: Adam Farber Project Location: Bulenga, Uganda Program Dates: July 2013 (2 weeks) Volunteered At: Orphanage and school What was your favorite memory of this trip? The kids. Theyre so great and so excited to have a guest teacher. Getting to know them over time and watching them learn was a great experience.  What was the most difficult thing you experienced? Figuring out how cautious to be with safety at night. As time went on it seemed fine to be out for a couple hours after dark if walking with a group, especially if with a local. For a later night in Kampala it was also easy to arrange a private driver for a reasonable fee. What was the one thing you wished you were better prepared for? Understanding what to worry about safety-wise. The quick answer is dont worry in Bulenga unless its been dark for a while and all the people have gone home. Of course there is no need to take unnecessary risks either, such as walking alone anytime at night or carrying lots of money or

And so to Connie. Yes, people on this thread are not flattering to Celia Farber (I would not use the word unkind myself). But theres a reason for that, in fact more than one. First, Ms Farber has done more than most to perpetuate the culture of death and destruction that is represented by the AIDS denialist movement in general, and the RA group in particular. When conduct so shameful occurs for so long, without any indications of repentance or regret, its perfectly appropriate to be critical. Second, even on this thread, and vastly more so on the denialists own Blogs, theres some extremely unkind things said about various people, including me, Seth and others, who take the time and trouble to fight the AIDS denialists. Perhaps Connie would wish to condemn also the abusive, defamatory, offensive, racist, sexist, homophobic and thoroughly nasty language that has been said about us, including by people who are closely linked to Ms Farber. There have been several occasions when she has ...

my husband was in Mercks PD-1 inhibitor ( keytruda) between Jan 2015 and June 2015. He was on the highest dose of 10mg/kg every 2 weeks. At the time, there was no clinical trial that would guarantee he gets a PD-1 inhibitor . There was only one that randomized between avastin or Opdivo blindly and we didnt want to get avastin at the time. Hence, we went with the keytruda study grouping solid tumors together at the highest dose. He never had a swelling. What happened was 2 month after enrolling, he started having subtle enhancements that the NO was not sure whether they are inflammation or recurrence. Things stayed this way with increased enhancements till in June we decided this cant be enhancement and he sat for a craniotomy that confirmed our doubts that this was definetly recurrence with minimal swelling or inflammation. The pathology was confirmed by Both Dana Farber and Johns Hopkins ...
Blogger Euan Semple recently highlighted a key point about Enterprise 2.0 adoption that ZDNets own Dan Farber also found worthy of note over the weekend. And that is that Enterprise 2.0 will happen in your organization entirely by itself, whether you encourage it, discourage it, or even consign it to benign neglect. Euan actually laid out three strategies in semi-tongue cheek form likely meant as a shot across the bow of complacent IT departments; whether you get out of the way, actively encourage it, or do absolutely nothing, Enterprise 2.0 platforms like blogs, wikis, and related social, emergent, freeform Web 2.0-style apps are coming to your company, and in fact are almost certainly there already.
