UMass Dartmouth professor lands $400K for cell imaging research

DARTMOUTH Maolin Guo, associate professor of chemistry and biochemistry at the University of Massachusetts Dartmouth, landed a $400,000 research grant from the National Science Foundation to support the development of a molecular imaging probe for cell research.

The three-year, $400,000 grant will help support Guos research efforts to develop new ways to detect iron ions in live cells at subcellular resolution.

According to an UMass Dartmouth release, the new imaging probes will help researchers to understand how iron ions affect health, which is important because we cannot live without it - literally. Iron carries oxygen throughout the body, is necessary in the creation of DNA, and iron levels are linked to hundreds of diseases including Alzheimers, Parkinsons and certain types of cancers.

We need a better understanding of the complex mechanism of how iron acts at the subcellular level to be able to successfully develop new pharmaceuticals and other treatments, said Guo in a statement.

Earlier this year, Guos laboratory became the first to see iron ions in live cells using their imaging probe. Using the National Science Foundation grant, Guo and his team will use the imaging probe to observe how iron acts in cells, opening up a new field of scientific and medical research, according to the release.

The insights gained from this study will allow us to monitor and image how iron affects living organisms, said Guo, and to develop therapies that can change irons effects on them.

Doctor plans to tour India

Dr. Subhash Basu, professor emeritus of chemistry and biochemistry, will embark on a speaking tour of India on Tuesday to discuss his current research on potential new anti-cancer drugs.

Basu will make his second appearance at the International Cancer Research Symposium on Dec. 19 in Calcutta when he gives a lecture titled Probable New Therapeutic Drugs for Breast and Colon Cancers.

The invitation to this symposium is very prestigious. Sixty people from all over the world are going to Calcutta, he said. I will tell them what our plan is for the delivery of these new anti-cancer drugs.

Basus lecture tour will also include an appearance at the Indian Science Congress on Jan. 4, where he will discuss the apoptotic, or cell-killing, effects of the drugs he is working with his collaborators to develop.

Our work is important, and we get an invitation every year to speak at these sorts of things, he said.

Basu said he and his research team have discovered five to six different new anti-cancer compounds that would be useful for treating colon and breast cancer patients.

These chemicals are quite toxic to biological cells and they kill cancer cells by enhancing apoptosis, or programmed cell death, in a very micro amount, he said.

Now that these cancer-killing compounds have been discovered, Basu said the main goal of his work is to determine ways to deliver the drugs into patients at the location of the cancer without harming the healthy cells around the cancerous ones.

Cancer cells normally die of necrosis they make holes in themselves, he said. When apoptosis happens, the cell gets bigger and its DNA starts degrading until the cell cannot function.

Basu said about 50,000 women die of breast cancer in the United States each year, so his research could impact thousands of lives in the future.

Iron holds key to immunity, shows study

Washington, Dec 4 (IANS) Researchers have figured out why iron plays a key role in metabolism and infections, pitting bugs and animals against one another, resolving a 40-year-old debate and opening way to more potent antibiotics.

The collaborative research, led by Phillip Klebba, professor and head of department of biochemistry at Kansas State University, clarifies how micro-organisms colonise animal hosts and how scientists may block them from doing so.

Klebba's team found that E. coli, one of the deadly bugs that cause hosts of gastric infections, must acquire iron from the host to establish a foothold and colonise the gut -- a concept that was often debated by scientists.

E. coli is difficult to get rid of because it has at least eight iron acquisition systems. So when one is blocked, another opens up, journal Public Library of Science ONE, reports.

The study, conducted with with Tyrrell Conway, microarray and bioinformatics researcher from University of Oklahoma, and Salete M. Newton, Kansas research professor of biochemistry, shows how iron acquisition affects the ability of bacteria to colonise animals, which is the first stage of microbial disease.

"This paper establishes that iron uptake in the host is a crucial parameter in bacterial infection of animals," said Klebba, study co-author, according to a Kansas statement.

"For years, it was theorised that iron is a focal point of bacterial pathogenesis (mechanism by which disease is caused) and infectious disease because animals constantly defend the iron in their bodies," Klebba said.

"Animal proteins bind iron and prevent micro-organisms from obtaining it. This is called nutritional immunity, and it is a strategy of the host defence system to minimise bacterial growth. But successful pathogens overcome nutritional immunity and get the iron," Klebba said.

"This is the first time our experiments unambiguously verified the indispensability of iron in infection, because here we created the correct combination of mutations to study the problem," he added.

Research Shows Iron’s Importance in Infection, Suggests New Therapies

Newswise MANHATTAN, KAN. -- A Kansas State University research team has resolved a 40-year-old debate on the role of iron acquisition in bacterial invasion of animal tissues.

The collaborative research -- led by Phillip Klebba, professor and head of the department of biochemistry -- clarifies how microorganisms colonize animal hosts and how scientists may block them from doing so. The findings suggest new approaches against bacterial disease and new strategies for antibiotic development.

The study -- in collaboration with Tyrrell Conway, director of the Microarray and Bioinformatics Core Facilities at the University of Oklahoma, and Salete M. Newton, Kansas State University research professor of biochemistry -- recently appeared in PLOS ONE. It shows how iron acquisition affects the ability of bacteria to colonize animals, which is the first stage of microbial disease.

"This paper establishes that iron uptake in the host is a crucial parameter in bacterial infection of animals," said Klebba, the senior author on the publication. "The paper explains why discrepancies exist about the role of iron, and it resolves them."

Iron plays a key role in metabolism, leading bacteria and animals to battle each other to obtain it. Klebba's team found that E. coli must acquire iron from the host to establish a foothold and colonize the gut -- a concept that was often debated by scientists.

"For years it was theorized that iron is a focal point of bacterial pathogenesis and infectious disease because animals constantly defend the iron in their bodies," Klebba said. "Animal proteins bind iron and prevent microorganisms from obtaining it. This is called nutritional immunity, and it's a strategy of the host defense system to minimize bacterial growth. But successful pathogens overcome nutritional immunity and get the iron."

Little was known about what forms of iron enteric bacteria -- which are bacteria of the intestines -- use when growing in the host, but this study shows that the native Gram-negative bacterial iron uptake systems are highly effective. Scientists questioned whether prevention of iron uptake could block bacterial pathogenesis. This article leaves no doubt about the importance of iron when E. coli colonizes animals because bacteria that were systematically deprived of iron became 10,000-fold less able to grow in host tissues, Klebba said.

"This is the first time our experiments unambiguously verified the indispensability of iron in infection, because here we created the correct combination of mutations to study the problem," Klebba said.

Enteric bacteria have so many iron transport systems that it's difficult to eliminate them all. For example, E. coli has at least eight iron acquisition systems.

"These transporters are redundant because iron is essential," Klebba said. "Bacteria are resilient. If one system is blocked, then another one takes over."

Duke Flags Lowered Tuesday: Former Biochemistry Chair Bob Hill Dies

Robert L. Bob Hill, Professor Emeritus and former Chairman of the Biochemistry Department at Duke University, died Thursday, November 29 at Duke University Hospital. He was 84. Dr. Hill is survived by his wife, Deborah Steege, his son Terry Hill, his daughters Amy Hill Gery (Frank), Geneva Hill (Jim), and Becky Hill Claycomb (Larry), and his five grandchildren.

Dr. Hill was one of the great protein chemists of his generation. He was instrumental in building the reputation and ranks of the Department of Biochemistry over nearly a half century career at Duke.

Bob Hill was born in Kansas City, Missouri, in 1928. He earned a bachelors degree in chemistry in 1949 and a Ph.D. in biochemistry in 1954, both from the University of Kansas. He then moved to the University of Utah for his postdoctoral fellowship with Emil L Smith. He continued his work on protein chemistry and enzymology as a faculty member at Utah for several years.

Dr. Hill joined the Duke faculty in 1961 as an associate professor. He was recruited to the Department of Biochemistry to work in the field of protein chemistry and enzymology. He established one of the most highly regarded protein chemistry labs in the world and did work on a range of proteins and glycoproteins, most notably, lactose synthase.

Dr. Hill was appointed Professor of Biochemistry in 1965 and James B. Duke Professor of Biochemistry in 1974. He served as Chairman of the Biochemistry Department at Duke from 1969 till 1993, building one of the strongest Biochemistry Departments in the world. According to colleagues, the departments environment under his leadership was exceptional, characterized by extraordinary morale and an almost family-like atmosphere. Under Dr. Hills direction, the visibility of Duke Biochemistry increased dramatically, with his own scientific achievements contributing significantly to the departments reputation.

While at Duke, Bob Hill received continuous NIH grant support for 42 years to study the structure and function of proteins and enzymes in his lab. Hill effectively trained and mentored numerous graduate students and postdoctoral fellows in his lab, many of whom have gone on to become leaders in biochemistry. He also directed Dukes MD/PhD program for many years and taught biochemistry to first-year medical students.

Bob Hill published 175 refereed papers over the course of his career. His accomplishments have been widely acknowledged by the scientific community, including election to the National Academy of Sciences, the Institute of Medicine, and the American Academy of Arts and Sciences. He received the William C. Rose Award from the American Society for Biochemistry and Molecular Biology in 1991, the North Carolina Gold Medal (for science) in 1985 and the Karl Meyer Award from the Society for Glycobiology in 2001. Hill served as President of the American Society of Biochemistry and Molecular Biology from 1976 to 1977 and had many executive leadership roles on national and international scientific societies. Hill served admirably on the editorial board of the Journal of Biological Chemistry for 47 years, one of the longest editorial services in the journals history. In recent years, he has played major roles in the popular JBC Classics series, which highlights important papers in the history of biochemistry.

Bob Hill will be missed by his colleagues both within and outside of the Department of Biochemistry at Duke, and by his many former students and postdoctoral fellows.

In lieu of flowers, memorial contributions can be made to the Robert L. Hill Biochemistry Education Fund. Please send contributions to Kristina Amidon, Major Gift Officer, Duke Medicine Development, 512 S. Mangum Street, Suite 400, Durham, NC 27701.

Arrangements for the Hill family are under the care of Hall-Wynne Funeral Services. Online condolences: http://www.hallwynne.com, select obituaries.
