We have a new member on the CIRM Board – Dr. Allison Brashear is the Dean of the UC Davis School of Medicine, overseeing one of the nation’s top research, academic and medical training institutions.

Dr. Brashear is an internationally known researcher in movement disorders and an expert in ATP1A3-related diseases, a spectrum of rare neurologic disorders.

Before joining UC Davis, Dr. Brashear was professor and chair of the Department of Neurology for 14 years at Wake Forest School of Medicine.

She serves on the American Board of Psychiatry and Neurology, and has served on the boards of the American Neurological Association and the American Academy of Neurology, where she was instrumental in crafting a leadership program for women, now expanded to include leadership development for minorities.

You can read more about her background in this news release. But we wanted to get a sense of what motivates and inspires Dr. Brashear. So we asked her. And she told us.

When did you get interested in science? Was this always something you knew you wanted to do?

I loved math and science in middle school and continued with science in college. I grew up hearing my parents talk about caring for patients and the impact you could have on them and their family’s lives. My father is a pulmonologist and my mother was a Ph.D. in marriage and family therapy. Together they taught me the value of patient-centered care. 

My mother was a tremendous advocate for women. When I was in middle school she took my friend and I to the state legislature and we watched the ERA (Equal Rights Amendment) debates. It’s a powerful memory but not always flattering about what people thought at the time. So, from an early age I really became a strong advocate for women, to make sure women had opportunities and that we were an inclusive culture wherever I was. 

As a woman going into a male dominated field, how did you manage to push past the skeptics and doubters to succeed? 

Early on I recognized the need to work with senior faculty who would give me an opportunity to lead and learn.  I became a chair of neurology at Wake Forest when I was 44 and was the only woman chair for 4 years. When I was appointed to the Wake Forest Baptist Medical Center Board of Directors as one of two faculty, I was the only woman. I learned early on that it was important to have sponsorship from senior leaders to succeed. I learned that, when opportunities presented themselves, to say “yes.” This is how I became the lead investigator into ATP1A3 related diseases in 1991. That project, now 11 years funded by the NIH, is one that is led by me and three other women. 

It’s still not uncommon for me to walk into a room and be the only woman. And so, making sure that there is appropriate support for women leaders is really key.

Did you have mentors to help you along the way – what was their advice to you?

I prefer the term sponsorship. Mentors advise – which is important, but more important is the role of the sponsor. A sponsor goes out of their way to advance another career. This can be a public call-out, a well-placed phone call or giving a resident what ends up being a new pathway of research.  I appreciate the many sponsors in my life, and that includes men and women.  I aspire to be a similar sponsor. This is my way to pay it forward. 

How do you sponsor others to help them overcome barriers, etc.? 

I advise women to get extra leadership training, learn about money and to make sure to have a network of advocates. I also remind them to say thank you to those who pave the way. 

I think it goes down to the message that you meet these key people in your life and they go the extra mile to help you and you, as a leader, need to take that opportunity and really just launch from it. Along the way I found I really wanted to bring people in and grow them and that was the best part of being chair of the department and one of the reasons I wanted to be a dean. When faculty join our health system I want to set them up to succeed. Celebrating others’ success with them is a great feeling. Fostering these successes is how we can be a catalyst to research and care innovations that improve health, which is at the heart of our work.  

These are interesting times to head a major university, what advice and encouragement do you have for students just starting out who face their first year “at university” at home? 

Every change brings opportunity. University at home is hard – interpersonal relationships are so important to learning and we miss that when we are on Zoom. I advise students and faculty to nurture those social connections.

When you are not working what do you do for fun?  

I hang out with my husband and our two rescue dogs. We are making plans to go explore California when the COVID-19 pandemic settles down. We had our two adult children home during the shutdown, but both are back at school on the East Coast. 

A recap on last week: two gut wrenching studies

With everyone stocking up on food essentials this past week, it brings to mind the vital role that our stomach plays in order to properly digest these foods. This week, we wanted to share two separate studies related to aspects of the gut.

Promising results for a gut-related condition

Gastroparesis is a painful condition in which the stomach is unable to empty itself of food. Symptoms include heartburn, abdominal cramps, nausea, vomiting, and feeling full quickly when eating. In extremely severe cases, patients can experience dehydration, malnutrition and bezoars, a small stone-like matter that forms when food hardens and can block the opening from the stomach into the pylorus (small intestine).

A new study, led by Dr. Prabhash Dadhich and Dr. Khalil N Bitar at Wake Forest School of Medicine showed how a stem cell-combo therapy could bring long-term relief to these patients.

The team of scientists used interstitial cells of Cajal (ICCs), a type of stem cell found in the gastrointestinal tract, in combination with neural stem cells. An animal model similar to gastroparesis was then made using tissue from the small intestine of rats. The combination of stem cells were then injected into the small intestine tissue, where the cells were able to survive and integrate with host muscle layers.

In a news release, Dr. Bitar explains how this approach could potentially restore stomach muscle function and enable normal food digestion.

“Our analysis also confirmed the reinstatement and restoration of the stomach muscles’ functionality, both of which are critical in the treatment of pylorus dysfunctionality. These findings are very promising. We hope this study opens avenues for future cell-based clinical applications.”

The full study was published in Stem Cells Journals.

Superbug can damage stem cells in the gut

A collaboration by the Monash Biomedicine Discovery Institute (BDI) has revealed that a bacterial superbug can prevent stem cells in the gut from regenerating the inner lining of the intestine.

Clostridioides difficile (C. diff) is a bacterial germ that is responsible for more than half of all hospital infections related to the gut and causes severe diarrhea. It usually grows after antibiotic treatment is administered to a patient.

The team of scientists found that C. diff damages stem cells in the colon, which in turn can cause problems with tissue repair and recovery.

In a press release, Professor Helen Abud, an expert in stem cell biology and one of the authors of this study, explains how this discovery can have wider implications.

“Our study provides the first direct evidence that a microbial infection alters the functional capacity of gut stem cells. It adds a layer of understanding about how the gut repairs after infection and why this superbug can cause the severe damage that it does. The reason it’s important to have that understanding is that we’re rapidly running out of antibiotics – we need to find other ways to prevent and treat these infections.”

The full results to this study were published in Proceedings of the National Academy of Sciences (PNAS).
