First Natural Product from Marine Myxobacteria
Posted On: June 6, 2013Although terrestrial myxobacteria have been extensively studied and are known to produce a range of secondary metabolites with a remarkable variety of unusual structures, their marine counterparts have only recently been discovered.
Gabriele M. König and co-workers, University of Bonn, Germany, have isolated a marine myxobacterium from a mud sample from the coast of the island Prerow, Germany. Analysis showed that the bacterium was Enhygromyxa salina, which is closely related to microorganisms previously termed “unculturable”. As this bacterium was found to have persistent antibiotic activity towards gram-positive microorganisms, it was chosen for detailed investigation.
FAU Harbor Branch awarded grant for pancreatic cancer research
Posted On: April 26, 2013Florida Atlantic University Harbor Branch Oceanographic Institute (HBOI) Marine Biomedical and Biotechnology Research Program (MBBR) scientists have been awarded a $345,716 grant by the National Institutes of Health (NIH) to identify marine natural products for their potential use in the treatment of pancreatic cancer.
A primary mission for the MBBR is to discover marine natural products that can be used as medicines or as tools to better understand the molecular basis of disease. MBBR has identified over 100 marine natural products with cancer fighting properties.
One current focus is to find potential treatments for pancreatic cancer, the fourth leading cause of cancer death in the United States. Pancreatic cancer has a 5-year survival rate of 6 percent, highlighting the need for new treatments.
Principal Investigator Dr. Esther Guzmán and co-investigator Dr. Amy Wright, director of the MBBR, plan to initiate a screening effort to discover inhibitors of the receptor for advanced glycation end products (RAGE) in pancreatic cancer cells using HBOI’s unique library of marine natural products. RAGE has emerged as an important regulator of inflammatory, stress and cell survival pathways, which contribute to the aggressiveness of pancreatic cancer.

Marine Institute and Department of Agriculture, Food and the Marine to co-fund food research
Posted On: April 3, 2013The Department of Agriculture, Food and the Marine Institute (DAFM) has announced a call for marine research projects relating to Food Innovation, Food Processing Technologies and Food for Health. Researchers in higher education institutions and research institutions and on the island of Ireland are invited to submit proposals under the Food Industry Research Measure (FIRM) in an initiative jointly funded by the Department of Agriculture, Food and the Marine and the Marine Institute.
The recent announcement by DAFM for research proposals under the Food Industry Research Measure (FIRM) reflects the importance of maximizing Ireland’s potential to exploit the commercial potential of our natural resources. In a continuation of collaboration between DAFM and the Marine Institute to co-fund strategic research, this FIRM programme includes a dedicated call for marine origin foods research; seeking to build on the investment made by both parties to the marine functional foods research initiative – NutraMara.
Comparison of Tamoxifen with Edible Seaweed (Eucheuma cottonii L.) Extract in Suppressing Breast Tumor
Posted On: March 21, 2013The extract of an edible red seaweed was found to be 27 percent more effective than standard chemo in shrinking breast tumors in rats while showing much less toxicity to liver and kidneys, and even improving the rats’ antioxidant status in both blood and tissues.
The tropical edible red seaweed (Eucheuma cottonii L.) is rich in nutrients and polyphenolic compounds that may suppress cancer through its antioxidant and antiproliferative properties. The study reports on rat mammary tumor suppression and tissue antioxidant status modulation by E. cottonii ethanol extract (ECE). The effect of orally administered ECE (100 mg/kg body-weight) was compared with that of tamoxifen (10 mg/kg body-weight). Rat was induced to develop mammary tumor with subcutaneous injection of LA-7 cells (6 × 10(6) cells/rat). The ECE was more effective than tamoxifen in suppressing tumor growth (27%), improving tissues (plasma, liver, and kidney) malondialdehyde concentrations, superoxide dismutase activity and erythrocyte glutathione concentrations (P < 0.05). Unlike tamoxifen, the ECE displayed little toxicity to the liver and kidneys.
The ECE exhibited strong anticancer effect with enzyme modulating properties, suggesting its potential as a suppressing agent for mammary gland tumor.
Biologists Engineer Algae to Make Complex Anti-Cancer ‘Designer’ Drug
Posted On: December 11, 2012Biologists at UC San Diego have succeeded in genetically engineering algae to produce a complex and expensive human therapeutic drug used to treat cancer.
Their achievement, detailed in a paper in this week’s early online issue of The Proceedings of the National Academy of Sciences, opens the door for making these and other “designer” proteins in larger quantities and much more cheaply than can now be made from mammalian cells.
FIRST NOTICE AND CALL FOR SYMPOSIA IMBC 2013
Posted On: December 4, 201210th International Marine Biotechnology Conference
Genome to phenome: understanding to sustainable use
Brisbane Convention and Exhibition Centre from 11-15 November 2013.
The International Marine Biotechnology Conference is the premier meeting in marine biotechnology and micro-biotechnologies. Dating back to 1989, previous IMBCs have been held in Japan (twice), The United States of America, Norway, Italy, Australia, Canada, Israel, China and Australia.
The 10th IMBC will showcase leading-edge developments in marine biotechnologies, from algal biotechnologies through to whole-organism biotechnologies and the application of marine genomics, metagenomics and chemistry in biomedicine, bioprocessing and aquaculture. Sustainable policies and practices will be at the fore throughout the conference.
Over the coming months further details about this meeting will come available, including a list of international plenary speakers and details on specific symposia. Along with this information, will be details on the registration, abstract submissions and trade displays.
Marine bioprospecting – a role for bioresource centers in the 21st century
Posted On: November 19, 2012Marine bioprospecting – a role for bioresource centers in the 21st century. A presentation by Dr Willie Wilson (Director of National Center for Marine Algae and Microbiota, Bigelow Laboratory for Ocean Sciences, USA) presentation at the Oceans of Potential conference, Tuesday 11th September, Plymouth, UK
Marine biotechnology promises huge benefits, but at what risk to our seas?
Posted On: November 17, 2012Scientists have pinpointed a new treasure trove in our oceans: micro-organisms that contain millions of previously unknown genes and thousands of new families of proteins.
These tiny marine wonders offer a chance to exploit a vast pool of material that could be used to create innovative medicines, industrial solvents, chemical treatments and other processes, scientists say. Researchers have already created new enzymes for treating sewage and chemicals for making soaps from material they have found in ocean organisms.
“The potential for marine biotechnology is almost infinite,” said Curtis Suttle, professor of earth, ocean and atmospheric sciences at the University of British Columbia. “It has become clear that most of the biological and genetic diversity on Earth is – by far – tied up in marine ecosystems, and in particular in their microbial components. By weight, more than 95% of all living organisms found in the oceans are microbial. This is an incredible resource.”
