Researchers from Mass General and the Whitehead Center for Genome Research find that most human genetic variation is organized into large, neat units called "haplotype" blocks. The scientists are participating in an international effort to construct a haplotype map that may make it faster and easier to identify gene changes associated with susceptibility to common diseases.
Mass General researchers identify a surprising new mechanism by which breast cancer cells metastasize to the lymph nodes and lungs, a pathway that may be a target for treatment strategies.
Mass General researchers discover stem cells within the pancreas that can generate insulin-secreting beta cells. Subsequent research may lead to ways to induce growth of a patient's own pancreatic islet cells for transplantation.
For the first time, Mass General researchers identify how common drugs called NSAIDS, which include aspirin and other anti-inflammatories, act on the central nervous system to reduce pain.
Mass General researchers devise a simple treatment that cures type 1 diabetes in mice. The approach essentially retrains the animal's immune system not to attack insulin-producing pancreatic beta cells.
Mass General embarks on a 20-year master plan to update the hospital's campus – including the building of two new outpatient facilities.
The first International Medical and Surgical Response Team (IMSuRT) of the National Medical Disaster System, based at Mass General, sees its first action in response to the September 11 tragedy in New York City. The Mass General IMSuRT and other Boston disaster teams treat more than 5,000 workers during the first 11 days after the disaster.

The second hospital-based proton therapy center in the world, the NPTC features the most advanced technology of its kind and a full range of patient and research support services.
Surgeons from the Mass General transplant team are the first to perform split-liver transplant procedures in the Northeastern U.S. The procedure, in which the liver from a single donor is divided between two recipients – usually and adult and a child – is another way to deal with the continuing shortage of donor organs.
A Mass General dermatologist develops new laser techniques that can safely remove unwanted hair from people with darker ethnic skin. Previously laser skin treatments had been ruled out for those with dark skin because of the risk of side effects.
A study led by a Mass General researcher finds that use of an experimental testosterone skin patch can relieve impaired sexual functioning in women who have had their ovaries removed before natural menopause.

A team from the Mass General Bone Marrow Transplant Center and the Transplantation Biology Research Center develop a new, less toxic preparative regimen allowing use of bone marrow transplantation from mismatched donors to treat certain blood-cell cancers. The technique is subsequently used to help induce immune tolerance in an organ transplant recipient. Simultaneous kidney and bone marrow transplantation treated the patient’s multiple myeloma and allowed discontinuation of immunosuppressive drugs without rejection of the kidney.
Mass General researchers are the first to induced the growth of severed adult mammalian spinal cord fibers across the site of the injury without the use of implanted cells or tissues to bridge the severed fibers.

A Mass General-based research team finds that elevated cholesterol appears to be a risk factor for preeclampsia, a condition of pregnancy that can have dangerous consequences for both mother and child. The discovery may lead to ways to reduce the risk of preeclampsia, something that is currently not possible.
An MGH research study identifies a gene malfunction that appears to be central to the development of type 1 diabetes. The study in a classic animal model of type 1 diabetes found that a gene required to help teach the immune system to recognize so-called "self" proteins is somehow inactivated, even though its sequence is not mutated.
A Mass General-based research team shows for the first time that gene therapy may be able to reverse heart failure. The researchers showed that delivering additional copies of a gene called SERCA2a to muscle cells from failing human hearts restored the cells to normal functioning. A follow-up study early in 2000 shows that delivering the same gene to the hearts of rats that are aged but not in heart failure can improve their cardiac function.
