How zebrafish are changing a approach doctors provide Maritime children with cancer

Inside a lab during Dalhousie Medical School, 12,000 zebrafish float in tanks that line a room from building to ceiling.

It looks like a pet store or an aquarium, though these guppy-sized fish have an critical tie to children being treated opposite a travel during a IWK Health Centre: they share a same cancers.

“That competence seem a tiny scholarship fiction,” says Dr. Jason Berman, a pediatric hematologist-oncologist at a Halifax hospital. “Remarkably, these tiny fish are genetically unequivocally identical to humans.

“And that’s unequivocally critical when we’re study cancer, since cancer is unequivocally a genetic disease.”

Berman, who treats children from opposite a Maritimes, transplants bone pith biopsies from his patients into a zebrafish during his lab during Dalhousie University. He can afterwards exam opposite drugs to see how a children competence respond to several treatments.

“Because a larvae are tiny and thin, we can usually wash them in a devalue of interest, that gets engrossed into a larvae and we can see responses,” he says.

Another advantage to using zebrafish is they can furnish about 200 transparent larvae. Cells are fluorescently labelled to give researchers a transparent perspective of what’s happening.

“If we can imagine, we have these florescent immature or blue tellurian cancer cells that are flourishing and dividing in the zebrafish and we can lane their transformation in a fish and how they behave,” says Berman.

There are several zebrafish labs opposite a country, though a Dalhousie trickery is a usually one that focuses on childhood cancers and singular genetic disorders.

Hannah Drake, a sea biology commune student, is spending this tenure operative in a lab. It’s her pursuit to arrange a fish in their tanks, creation certain they have room to grow and are being fed correctly. 

“I never suspicion I’d be operative with cancer and fish,” she says. “It’s positively extraordinary usually to get to participate.”

Berman creates certain his patients are concerned in a process. He brings families opposite a travel to see a work first-hand.

“They can come and see how we injected their samples into a fish and how a fish is working with those transplanted cells,” he says.

Zebrafish conflict fast to new treatments — within a week or so — which is something Berman says has a intensity to change a approach cancer is treated in a future.

“So a thought would be that we can use this to assistance personalize therapy in patients during a time that they have a biopsy of their cancer and there competence be a integrate of opposite treatments that are being considered.”

While Berman focuses mostly on leukemia, sarcomas and neuroblastoma, a lab has also finished work with some adult cancers including breast and lung cancers.
