Thursday, October 9th, 2014

HealthLink on Air radio show art in pinkBreast cancer researchers share their projects. Leszek Kotula, MD, PhD, and Steve Landas, MD, explore which drugs will work best in each patient. Megan Oest, PhD, investigates how to better protect bone from radiation therapy. Debashis Ghosh, PhD, explains the best way to inhibit estrogen. Christopher Turner, PhD, and Nicholas Deakin, PhD, search for ways to halt the spread of breast cancer.


Which drug will work best in each breast cancer patient?

Thursday, October 2nd, 2014

Steve K Landas, MDLeszek Kotula, MD/PhD

A family of molecules known as the Wave Complex interact within our cells. Which molecular family members are present at any given time in the life of a cell determines how that cell will behave: how it gets nutrition, whether and how it moves, whether it remains stationery.

 This complex appears to play a major role in the invasive types of breast cancer, says Leszek Kotula, PhD, associate professor of urology and biochemistry and molecular biology. Working on the theory that the Wave Complex could be a target for therapy are Kotula and two colleagues, Steve Landas, MD, professor of pathology and urology, and Mira Krendel, PhD, assistant professor of cell and developmental biology.

When they increase some specific molecules in the complex, the cancer spreads, Kotula says. He adds that by decreasing certain molecules, “we may actually stop metastasis, or greatly affect it.”

The next step will be to test the effects of existing cancer drugs on these molecules. Landas, a diagnostic pathologist for 35 years, sees the potential. “Wouldn’t it be a wonderful thing if we find ourselves in a situation where we can look at certain members of this family of molecules and know with a high degree of certainty which drugs will work and which will not?”

Kotula and Landas are among dozens of researchers who have received grants from the Carol M. Baldwin Breast Cancer Research Fund of CNY since 2002.


What will stop the spread of breast cancer?

The protein, paxillin plays an important role in cell movement. What scientists are trying to determine is exactly how paxillin affects the movement of cancer cells away from a primary tumor, into the blood stream and on to colonize distant organs. It’s important to know because “If we can develop ways in which we can limit paxillin’s function, we may be able to block the process of metastasis,” says Christopher Turner, PhD, professor of cell and developmental biology.

 Many of the drugs used to fight breast cancer tumors target microtubules, the proteins that makes up the cytoskeleton that helps cells maintain their shape and internal organization. These drugs create toxic side effects for patients.

“We found that the level of expression of paxillin in tumor cells may actually influence the microtubule cytoskeleton and, therefore, may influence how those drugs actually work in individual patients,” Turner says.

Nicholas Deakin, PhD, research assistant professor of cell and developmental biology, points out that the deaths of 95 percent of the 40,000 American women who die from breast cancer each year are linked to metastasis. “It’s not the tumor in the breast that really is the problem. It’s the ability of the cells to move away from there,” he explains. “If we can detect the tumors early, and if we can then treat them with a drug or know what drug to go with to stop their spread, then that’s going to greatly influence the survival of these patients.”

Exploring how to better protect bone from radiation therapy during cancer treatment

Targeted radiation therapy can be effective in reducing the size of a tumor, but it can leave bones more susceptible to fractures in the years after cancer.

Studying stem cells for possible solutions are Megan Oest, PhD, assistant professor of orthopedic surgery, and Timothy Damron, MD, professor of orthopedic surgery, cell and developmental biology and neuroscience and physiology. Stem cells have the ability to develop into many different cell types, depending on the body’s needs.

Of the bone cells that are alive at the time of radiation, Oest and Damron have noticed that some die and are never replenished. They are experimenting with chemical or biological methods to prevent damage to these particular cells. Perhaps in the future, patients could receive an injection of a protective substance before undergoing radiotherapy.

 It’s also possible, Oest theorizes, that patients could undergo something like a stem cell transplant after their therapy. Healthy cells could come from a donor, or from elsewhere in the patient’s body. She and Damron have learned that when radiation is applied to one leg, cells from the opposite leg remain undamaged. “In theory, if it worked, you could actually take cells from the healthy side of the patient and put them into the unhealthy side,” she says.

Oest and Damron are among dozens of researchers who have received grants from the Carol M. Baldwin Breast Cancer Research Fund of CNYsince 2002.

Breast cancer high risk program

Tuesday, April 1st, 2014

Jayne Charlamb, MDJayne Charlamb, MD, medical director of prevention and survivorship at Upstate, talks about a program designed for women who are at an increased risk of breast cancer.  Charlamb is the director of Upstate’s breast cancer high risk program, which offers special surveillance options as well as “chemoprevention” – taking medication to reduce their risk of developing breast cancer. For more information, call (315) 464-8224, ask for Linda.
