Beyond BU for the Summer: Alexandra Lion Completes Intensive Embryology Course
Alexandra Lion is a PhD candidate in the Bradham Lab, which studies pattern formation during embryonic development using the larval skeleton of the sea urchin Lytechinus variegatus as a model. Her projects focus on the role of the DEAD-box RNA helicase DDX6 in temporal regulation of development, and on the effect of per- and polyfluoryl alkyl substances (PFAS) on embryonic development and patterning.
Alexandra recently spent part of her summer attending the Marine Biological Laboratory course, Embryology: Concepts and Techniques in Modern Developmental Biology. The Embryology Course is an intensive six-week laboratory and lecture course for advanced graduate students, postdoctoral fellows, and more senior researchers who seek a broad and balanced view of modern issues in developmental biology.
Alexandra describes her experience below:
I applied to the Embryology course at the Marine Biological Laboratory because I wanted to expand my knowledge and connections within the field of developmental biology, as well as get more hands-on experience with a greater number of model organisms. Through this 6-week course, I was exposed to a wide range of well-established models such as Drosophila, zebrafish and C.elegans, as well as emerging model systems like acoels, cephalopods and ctenophores. I was able to greatly expand my microscopy experience since we were provided dozens of microscopes from vendors including Nikon, Leica, Andor and Zeiss. Having access to such a wide range of tools and organisms allowed me to try experiments that were outside of my prior expertise, such as lineage tracing, photo conversion, laser ablation, tissue grafting and more. This course really reinvigorated my sense of curiosity and opened my eyes to just how many unanswered questions there still are to probe. It helped that the course directors and faculty were enthusiastic about our ideas, and encouraged us to try any experiment we wanted to no matter how out-of-the-box. The faculty and course assistants frequently stayed in the lab with us students late into the night to help troubleshoot our experiments, and really supported all of our efforts.
The course introduced me to many people in the field, from other graduate students and postdocs to faculty who have been doing research for decades. Getting to work with the faculty in close quarters for up to a week at a time was incredibly valuable; you really get a feel for how the faculty are to work with, and how they might be as mentors. I also made a lot of really incredible friends through my time at Embryology; spending 6 weeks in the lab together, sharing all of our triumphs and setbacks at the bench, but also doing non-science things like practicing for the Embryology vs. Physiology softball game together really bonded us all. I’m grateful to have these people as both my friends and colleagues, and am excited to reunite at future conferences and events.
My attendance at the course was funded in part by a Max M. Burger Endowed Scholarship in Embryology and by the Society for Developmental Biology. Thank you also to the Biology Department and MCBB Program for their support, and to my advisor Cynthia Bradham for her encouragement and support of my attendance.

Anna Berenson Receives 2024 Belamarich Award
Dr. Anna Berenson of the Fuxman Bass Lab was selected as the winner of the Biology Department's 2024 Belamarich Award for her doctoral dissertation in Molecular Biology, Cell Biology & Biochemistry titled “Paired Yeast One-Hybrid Assays to Detect DNA-Binding Cooperativity and Antagonism Across Transcription Factors.” The selection committee was impressed by the quality of Anna’s work, its combination of methods development, observational studies, and computational analyses, and its potential for informing future research in the field of gene regulation. More information about her research is below.
For her dissertation, Anna developed paired yeast one-hybrid (pY1H) assays to study interactions between pairs of transcription factor (TF) proteins and DNA regions of interest. In addition to identifying cooperative DNA binding of TF pairs, pY1H assays also revealed extensive DNA-binding antagonism between TFs, constituting a previously underappreciated mechanism to regulate TF-DNA binding. Anna further applied pY1H assays to study the role of TF-TF relationships in cytokine gene regulation, the effect of alternative TF isoform usage on these relationships, and the effect of viral proteins on human TF-DNA binding. This work contributes to our understanding of how TF-DNA interactions are specified and provides a useful method that can be applied to further elucidate TF-TF relationships and their role in transcriptional regulation.
Anna will be continuing her academic career as a postdoctoral researcher in the lab of Dr. Jef Boeke at the NYU Langone Health Institute for Systems Genetics.
Congratulations, Anna!

Jillian Ness Receives 2024 Marion R. Kramer Scholarship
Jillian Ness of the Wunderlich Lab is one of the recipients of the Biology Department's 2024 Marion R. Kramer Scholarship. Jillian and her team studied how enhancers work in development, focusing on redundant enhancers, or “shadow enhancers,” linked to developmental genes. These enhancers are remarkably abundant in animals and can compensate under conditions of stress to drive normal development.
She is exploring how these enhancers function, as well as how they are created and maintained in animal genomes. Her work involves creating simplified enhancer models in Drosophila and analyzing how they work. In parallel, she performs evolutionary studies on shadow enhancer sequences to understand genomic events from which the sequences originate. Ultimately, she aims to understand enhancer sequences to improve predictions of perturbations that lead to developmental disease in embryos.

Congratulations, Jillian!
Mandy Pinheiro Receives 2024 Belamarich Dissertation Writing Award
Mandy Pinheiro of the Naya Lab received the Biology Department's 2024 Belamarich Dissertation Writing Award. This award complements the Belamarich Award, and is given to support an outstanding PhD student through the dissertation writing stage.
Mandy’s research focuses on understanding how noncoding RNAs (ncRNAs) may be central to the coordination of metabolism and differentiation in skeletal muscle. The regulation of gene expression during cell state transitions is a complex and tightly controlled molecular process. One potential central regulator of myogenesis is the Dlk1-Dio3 ncRNA locus, the largest known mammalian cluster of ncRNAs. She used mouse skeletal muscle cells as a model system to investigate how this ncRNA cluster may coordinate metabolic and epigenetic changes that occur when proliferating myoblasts differentiate into mature myotubes.
Congratulations, Mandy!
Green Lab Publishes Patent for Detecting Nucleic Acids
Milad Babaei, MCBB PhD student of the Green Lab, and Dr. Zhaoqing Yan (GRS '23), along with their mentor, Dr. Alexander Green, are co-authors on a recently published patent. This patent, titled "Isothermal Nucleic Acid Detection Assays and Uses Thereof" by Green et al. (US Patent 2023/0313283, October 2, 2023), describes rapid methods for detecting nucleic acids, from viruses to circulating mRNAs, in low-cost portable formats.
Nucleic acids, such as DNA and RNA, play a crucial role in genetic information. "Isothermal" refers to processes that occur at a constant temperature. In the context of nucleic acid detection, isothermal assays are methods that allow the amplification and detection of nucleic acids at a constant temperature without the need for thermal cycling, as in PCR (Polymerase Chain Reaction).
The team is currently expanding its panel of detection by developing lateral flow strips that can spontaneously probe for multiple targets using multiple test lines. This capability is crucial for the future of detecting and analyzing nucleic acids, which are fundamental in various fields, including medical diagnostics, research, and biotechnology.
Congratulations, Dr. Alexander Green, Milad Babaei, and Dr. Zhaoqing Yan!
