Researchers have created a detailed catalog of gene-isoform variations in the developing human brain, revealing significant implications for understanding and treating neurodevelopmental and psychiatric disorders. Their work has uncovered over 214,000 unique isoforms and highlighted the dynamic changes in isoform expression that occur during brain development. Credit: SciTechDaily.com
“We knew, based on our previous research, that isoform regulation is a key molecular feature for understanding brain development and genetic risk for neuropsychiatric disorders,” said Dr. Luis de la Torre-Ubieta of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, who co-led the study alongside Dr. Michael Gandal, an associate professor of psychiatry and genetics in the Perelman School of Medicine at the University of Pennsylvania.
“These tissue samples enabled a striking level of novel transcript discovery,” Gandal said. “And because these databases haven’t incorporated or represented these critical time points, we can dramatically expand our understanding of how genes are regulated in the context of human brain development.”The findings from the study have strong therapeutic implications and could be clinically actionable, the researchers said.

Birdsong and human voice built from same genetic blueprintHumans have been long fascinated by bird song and the cacophony of other avian sounds -- from coos and honks to quacks and peeps. But little is known about how the unique vocal organ of birds -- the syrinx -- varies from species to species or its deeper evolutionary origins. A trio of recent studies is changing that.
