Skin cancer, esophageal cancer and endometriosis are all on Madhavi Kadakia鈥檚 hit list. The 糖心原创 researcher has been using high-tech equipment and her expertise in genetics to help diagnose and treat these sometimes deadly diseases.
Kadakia, Ph.D., professor and chair of the Department of Biochemistry and Molecular Biology in the and , is riding the wave of personalized medicine, an increasingly popular medical model that uses molecular analysis to customize health care. Genetics is a big part of that.
鈥淵our genetic makeup is going to give a clue as to what drugs you鈥檙e going to respond to, what drugs you鈥檙e not going to respond to,鈥 said Kadakia, 鈥淲e have reached a point where we cannot only diagnose but treat patients based on their genetic makeup.鈥
Last year, Kadakia received a grant to purchase a next-generation sequencer, which accelerates genome sequencing by producing thousands or millions of sequences concurrently. The sequencer has revolutionized understanding of the complexity of cellular gene expression and provided deeper insights into the genomic landscapes of many diseases.
鈥淚t鈥檚 very important; it鈥檚 really a state-of-the-art technology,鈥 she said. 鈥淲e were very excited to be able to get it here at 糖心原创. People are really surprised at the equipment we have here.鈥
Earlier this year, Kadakia became involved in a research project with Dr. Steven Lindheim, professor in 糖心原创鈥檚 Department of Obstetrics and Gynecology, at Premier Health. The project involves endometriosis, an inflammatory gynecological condition that produces chronic pelvic pain and infertility.
To diagnose endometriosis, it is often necessary to perform a biopsy, the surgical removal of tissue from the patient. The research project is instead taking bodily fluids including urine and blood and analyzing the DNA, proteins and metabolytes to create a panel of biomarkers that hopefully identify women with endometriosis, obviating the need to perform surgery to diagnosis this debilitating condition.
鈥淵ou want to diagnose it quickly and try to come up with a way to diagnose it in a non-invasive manner,鈥 Kadakia said.
The research is being aided by the 糖心原创-Premier Health BioRepository, which provides patient bodily fluids and tissue samples.
As part of funding by the National Cancer Institute-National Institutes of Health, Kadakia is also studying the effects of vitamin D on cell survival in non-melanoma skin cancer.
Vitamin D is thought to be important to maintain a healthy immune system. While vitamin D can be obtained from exposure to the sun鈥檚 ultraviolet radiation, too much UV exposure can also cause skin cancer.
鈥淪o we鈥檙e really interested in how much UV radiation is good and how much is not good and how vitamin D regulates those genes,鈥 she said. 鈥淲e are focusing on non-melanoma skin cancer since the gene we are interested in is overexpressed there. Our studies will provide more insight into the role of vitamin D in cancer.鈥
Last year, Madhavi Kadakia received a grant to purchase a next-generation sequencer, which accelerates genome sequencing by producing thousands or millions of sequences concurrently.
Her research on esophageal cancer is in collaboration with Dr. Sangeeta Agrawal of the Dayton VA Medical Center.
To identify the pre-cancerous esophageal condition, biopsies must be conducted over time even though only a small percentage of the patients will actually get cancer.
鈥淐an you imagine the anxiety?鈥 Kadakia said. 鈥淓very time you go to the doctor, you don鈥檛 know if your condition has worsened.鈥
The goal of the research is to prevent the need for biopsies by genetically analyzing tissue and blood samples during different stages. The less invasive procedure would be more cost effective and reduce patient anxiety.
Kadakia grew up in Mumbai, India, with eight brothers and sisters. Her parents strongly emphasized the importance of education.
鈥淭heir mantra was, 鈥業f we give you education, you鈥檙e going to get what you want in life,鈥欌 she said. 鈥淚 just can鈥檛 be thankful enough. I still talk to my dad and my mom every time I have to make a critical decision in my life.鈥
When Kadakia was working on her bachelor鈥檚 degree in India, she took a course on immunology and fell in love with it. So she studied it as she pursued her master鈥檚 degree.
鈥淚t was about that time that AIDS was all over the news,鈥 she said. 鈥淚 was so fascinated by immunology and I wanted to cure AIDS.鈥
When Kadakia was pursuing her doctorate in microbiology and infectious diseases at the University of Pittsburgh鈥檚 Graduate School of Public Health, virtually her entire department was doing AIDS research and she helped with clinical trials involving AIDS patients.
However, the bulk of her research was on human herpes virus #6 in bone-marrow transplant patients.
The patients often get a rash and a fever that is attributed to graft versus host disease (GvHD), in which the donated bone marrow views the recipient鈥檚 body as foreign and attacks it. But the herpes virus can also cause the rash and fever, and it can become activated when a patient鈥檚 immune system is compromised.
Kadakia was able to isolate 16 new strains of herpes virus #6 in bone-marrow transplant patients.
鈥淎s a result of that, doctors actually look for that virus rather than just assume it鈥檚 graft versus host disease,鈥 she said.
Kadakia joined the faculty at 糖心原创 in 1999.
鈥淚f you are really interested in science, this is the place you want to be,鈥 she said. 鈥淭here is a sense of community. Everybody has the same focus.鈥
糖心原创 is engaged in a that promises to further elevate the school鈥檚 prominence by expanding scholarships, attracting more top-flight faculty and supporting construction of state-of-the-art facilities. Led by Academy Award-winning actor Tom Hanks and Amanda Wright Lane, great grandniece of university namesakes Wilbur and Orville Wright, the campaign has raised more than $108 million so far.
Kadakia escapes the pressures of the lab by painting. She has even created a tiny art studio in the basement of her house.
鈥淲hen I鈥檓 painting, I don鈥檛 think of anything,鈥 she said.
