Topic: BMAA


  
  Dietary neurotoxin linked to Alzheimer's - 02 August 2004 - New Scientist
A neurotoxin called BMAA found in the fruit of the cycads on which the flying foxes feed is thought to become concentrated in the flying foxes' flesh.
BMAA, in turn, is made by a blue-green alga, or cyanobacterium, that lives in the roots of the cycads (New Scientist print edition, 10 January).
Levels of this protein-bound form of BMAA in the cycad flour eaten by islanders, in the flesh of flying foxes and in the brains of ALS/PDC victims, are typically around a hundred times higher than that of the free form, the team found.

Research showed that while BMAA can cause neurodegeneration in monkeys, in order to get toxic effects from cycad flour, a person would have to eat a heck of a lot of it, said Cox.
Further investigation revealed similar results: BMAA was discovered in brain tissue from eight Canadian Alzheimer's patients, but not in 14 others who had died from causes other than neurodegeneration.
Mash said BMAA has showed up in all of the brain samples from ALS and Alzheimer's patients that have been tested by her lab.

 The Cycad Pages   (Site not responding. Last check: 2007-10-31)
BMAA is a non protein amino acid and is found in all genera but at highest concentrations in the genus Cycas, which is found in Guam, Kii Peninsula and New Guinea.
BMAA is thought to be weakly excitotoxic to neurons by acting at the
Cycad seeds contain low concentrations of BMAA (Charlton 1992) and up to 80% of this was removed after processing (Duncan letter to Lancet).

 Genome Biology | Full text | Expressed sequence tag analysis in Cycas, the most primitive living seed plant
BMAA is neurotoxic in mammals [9,13] because of its excitotoxic action as an agonist of glutamate receptors (GLRs) [14].
BMAA, an agonist of mammalian GLRs, is a suspect causative agent of neurological disorders [9,13].
Considering the prevalence of BMAA in Cycas, it is not surprising that we discovered cognate genes for the predicted enzymes for this BMAA biosynthetic pathway in the cycad EST database (Figure 5, Table 2).

 Toxin Found In Brains Of Dead Alzheimer's Victims Substance Made By Algae Common In Lakes, Oceans
BMAA is produced by cyanobacteria, ubiquitous algae common to lakes, oceans and the soil, and can build up in the food chain.
Cox and his colleagues believe the BMAA produced by the algae may also act as a "slow toxin." They chemical can be bound by proteins, and gradually released over many years.
BMAA's chemical signature in the brains of Canadian Alzheimer's patients indicates the problem may not be unique to Guam.

 Cyanobacteria linked to neurological disease
Until recently, BMAA was known only from cycads, plants of warm areas of the world that are sometimes eaten by indigenous people such as the Chamorro of Guam.
Cox, Canadian scientist Dr. Susan Murch, and Dr. Sandra Banack at California State University, Fullerton, found that BMAA is produced by cyanobacteria resident in the roots of the cycad trees.
Interest in the hypothesis increased when BMAA was found in the brain tissues of several Alzheimer's disease patients in Canada.

 Cyanobacteria (“blue-green algae”) produce toxin with possible connection to neurodegerative disorders
Previously scientists thought that BMAA was produced only by cone palm trees, which are extremely common in that part of the world and have sometimes been used as food.
High levels of BMAA have been found in the brains of disease victims in Guam, but since BMAA has recently been discovered in the brains of Alzheimer's patients in Canada, the hunt for the sources of the BMAA toxin has been intensified.
Recently Paul Cox and his associates in the U.S. showed that BMAA is produced by a cyanobacterium that lives in the roots of the cone palm rather than in the plant itself.

Wayne Carmichael, professor of aquatic ecology and toxicology at Wright State University in Dayton, Ohio, is not surprised Cox found BMAA everywhere.
Shaw said it's possible that Cox's research is not picking up BMAA in diseased brains, but rather a similar substance that is produced in the brain as the result.
And that so far, between 40 and 50 brain samples from patients with brain diseases have tested positive for BMAA among all the labs that are looking for it worldwide.

 Neurotoxin is absent from Cyanotech’s spirulina
Ninety-seven percent of the free-living cyanobacteria strains tested and 73 percent of the strains isolated from symbiosis were shown to produce BMAA, but spirulina, blue-green vegetable algae rich in beta carotene, iron, vitamin B12 and gamma linolenic acid, was not included in the study.
Dr Cox and colleagues not only identified a link between BMAA and an Alzheimer's-like disease suffered by the Chamorro people of Guam, who eat the seeds of BMAA-producing cycad plants, but also said that their data demonstrate that BMAA is produced by cyanobacteria from geographical regions and diverse environments throughout the world.
They advocated the monitoring of BMAA in sources of drinking water and in invertebrates, fish, or grazing animals used for human consumption that either directly consume cyanobacteria or forage on plants or prey that may have accumulated cyanobacteria-produced BMAA.

 Baptist Missionary Association Directors Promote Ecumenical Method - by Bill Mosley
The denomination of the churches is not given so it may not matter to the BMAA directors even if they know.
It would be interesting to know how many of these "over 3,000 churches" have the name "Baptist." It may matter little to some even in the BMAA whether or not the name "Baptist" is used on their sign.
However, his church affiliation should be of great concern to the Lord's churches and their pastors since the BMAA directors have accepted help from the organization which he directs.

"BMAA accumulates at high levels in cycad seeds, which are eaten by flying foxes, a traditional favorite of Chamorro feasts," Dr. Cox noted.
The discovery that protein-bound neurotoxic BMAA "accumulates in the body as a neurotoxic reservoir, slowly trickling out over years and decades as proteins are metabolized...may account for the observed latency of ALS/PDC in Chamorro people," Cox explained.
This week in PNAS, they report finding protein-bound BMAA in brain tissue from six Chamorro patients with neurological disease, one of two Chamorros who had not been diagnosed with neurodegenerative disease as well as in eight of nine brain tissue samples from Canadian patients with Alzheimer's disease.

 ES&T Online News: Potent neurotoxin found in blue-green algae
Cycads, for example, are thought to be the source of BMAA found in the brains of people in Guam who died from a paralytic disease similar to Parkinson's.
More recently, however, BMAA was discovered in brain tissues of Alzheimer's patients in Canada.
Therefore, the researchers recommend monitoring BMAA concentrations in drinking waters contaminated by cyanobacterial blooms, as well as in invertebrates, fish, or grazing animals used for human consumption.

Although the evidence associating cyanobacteria-produced BMAA as a plausible source for neurotoxin that harms humans is mounting, the overall case remains “controversial,” Cox says.
The case in favor of BMAA was reinforced recently when researchers at the University of Miami similarly detected BMAA in archived specimens of brain tissues from patients who had Alzheimer's disease, he notes.
Another component of this controversy is the hypothesis that BMAA is “bound to” or incorporated into proteins within the central nervous system, possibly serving as an “endogenous neurotoxic reservoir” from which this small molecule could be released gradually to cause damage over long periods.

BMAA is detected using precolumn derivatization with 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate (AQC), a reverse phase gradient HPLC separation, fluorescent detection, and LC/MS confirmation.
Although the free BMAA levels were much lower than the “protein-associated” levels, most evidence for BMAA supports the free molecule as the proximate neurotoxin perhaps acting as an excitotoxin.
If BMAA is incorporated into proteins, leading to protein dysfunction or an immune reaction, this would be a remarkable and novel mechanism of toxicity that will require very rigorous identification of which proteins are involved to take this beyond conjecture.

 New Cyanobacteria link to neurodegerative disorders - SWEDEN.SE   (Site not responding. Last check: 2007-10-31)
Now a research team from Sweden, Scotland, and the US has found that a further toxin (BMAA, -methyl amino-alanine), with a possible connection to degenerative nerve diseases like ALS, Alzheimer’s, and Parkinson’s, is produced by cyanobacteria that are widespread around the world.
Swedish collaborators in the project are Professor Birgitta Bergman and Associate Professor Ulla Rasmussen at the Department of Botany, Stockholm University.
High levels of BMAA have been found in the brains of disease victims in Guam, but since BMAA has recently been discovered in the brains of Alzheimer’s patients in Canada, the hunt for the sources of the BMAA toxin has intensified.
