Work on Neuronal Communication Published in Molecular Cell by the Garcia-Marcos Lab

The Garcia-Marcos Lab has recently published a study in Molecular Cell titled, “Fine-tuning GPCR-mediated neuromodulation by biasing signaling through different G protein subunits.” 

The paper describes how various signaling responses triggered by the same neurotransmitter receptor must be carefully scaled to ensure proper brain function. They found that the protein named GINIP shifts the balance of two different G protein sub-species activated simultaneously by G protein-coupled receptors (GPCRs), a large family of surface receptors that respond to many neurotransmitters and neuropeptides (GABA, dopamine, serotonin, or opioids). 

This mechanism operates in synapses that dampen neurotransmission and, when disabled, results in increased seizure susceptibility in mouse models. These findings have important implications for the fundamental understanding of neuronal communication and for the development of new therapeutic agents that act on GPCRs.

 

This work was co-led by Jong-Chan Park (Postdoc) and Alex Luebbers (Graduate Student) with collaborations from the Martemyanov Lab at UF Scripps Biomedical Research Institute and the Yano Lab at Northeastern University, and has been highlighted by Molecular Cell and Science Signaling.

So Young Bae Wins Poster Prize from the American Crystallographic Association

By Jen CorreiaJuly 21st, 2023in Grad Student News

So Young Bae, MCBB PhD student in the Tolan Lab, won the Journal of Chemical Crystallography poster prize at the recent international meeting of the American Crystallographic Association in Baltimore Maryland this past July 2023. The American Crystallographic Association is the preeminent society supporting structural science at all levels and disciplines. The Journal of Chemical Crystallography Poster Prize recognizes the best student, graduate or undergraduate, poster presentation in the area of chemical crystallography.

So Young’s poster was entitled, “Mode of Substrate Binding for Ketohexokinase across Isozymes and Species Implies an Induced-fit Mechanism.”  Her award was acknowledged at the closing banquet. Her presentation showed that one of the most important isozymes, ketohexokinase-A (KHK-A), which is involved in moonlighting as a protein kinase and has roles in regulating expression of genes important in cancer cells, can undergo a conformational change. She showed this structural change by solving the first ever structure of mouse KHK-A by X-ray crystallography and revealing differences in structure from what was previously known. She also solved the structure of human KHK-A in complex with one of it’s natural substrates, fructose. This structure revealed yet another distinct structural difference from the either the unbound enzyme or the enzyme bound with both substrates. Her work will eventually determine if these structural changes are part of the switch from a sugar kinase to a protein kinase.

Congratulations, So Young!

2023 Dr. Marion R. Kramer Scholarship Winners

By Jen CorreiaJuly 19th, 2023in Grad Student News

The Department of Biology is excited to announce the three recipients of this year’s Dr. Marion R. Kramer Scholarships: Hannah Axten of the Ho Lab, Alanna Carey of the Chen Lab, and Yuan Tian of the Man Lab.

Hannah studies a member of the forkhead box (FOX) family of transcription factors, FOXR1, and its role in neurodevelopment. A human patient identified by the NIH Undiagnosed Disease Network with a heterozygous mutation in FOXR1 displays developmental delay, progressive brain atrophy, and microcephaly. Mice null for foxr1 phenocopy aspects of the patient phenotype. She is currently investigating how loss of foxr1 leads to abnormal brain development in transgenic mice.
Alanna's research project aims to gain an understanding of the neurobiology of individual differences and examine genetic contributions to behavior in a controlled environment. The overarching hypothesis for this project is that individual differences in goal-directed learning arise through genetic variation at the gene expression, neural circuit, and behavioral levels. The recently developed, genetically heterogeneous mouse strain Diversity Outbred (DO) mimics the human population’s genetic variation while allowing for investigations of complex phenotypic traits in a controlled environment. Mice are subjected to an automated, cognitively demanding spatial learning paradigm to determine the genetic contributions driving the rate of learning performance through Quantitative Trait Loci analysis (QTL) while tracking their task-related and offline behaviors. By comparing DO mice to the 8 inbred founder mouse lines, learning performance was highly variable for DO mice and group differences were observed between inbred lines that spanned the variation observed in DO mice. Behavioral analysis from lick sensors and videography suggest that individuals employ a range of motor strategies to perform the task. This work will provide evidence for intrinsic factors that govern aspects of learning that can be further investigated using genetic strategies.
Yuan's research focuses on Autism Spectrum Disorder (ASD) associated with the overexpression of Ube3A, one of the most common genetic factors in ASD etiology. She studies the molecular mechanisms underlying defective excitatory synaptic activity, as well as the presence of, and mechanisms behind, sexually dimorphic changes in cellular features, gene expression, neuronal activity, and autistic behaviors in Ube3A-dependent ASD.

This award provides support for high-achieving female students majoring in Biology. The award was established in 2001 in honor of Dr. Marion Kramer who earned her Bachelor’s degree in Biology from Boston University in 1963 and went on to a long and satisfying career in biology and medicine.

Congratulations, Hannah, Alanna, and Yuan!

E Schlatter Receives 2023 Dana Wright Fellowship

By Jen CorreiaJuly 18th, 2023in Grad Student News

E Schlatter of the Buston Lab is the 2023 recipient of the Dana Wright Fellowship.

E uses a variety of theoretical and empirical approaches to address questions about the evolution of marine larval dispersal. Their current projects include: using quantitative genetics to ask about the evolutionary potential of dispersal-related traits in the clownfish Amphiprion percula; using a theoretical model to illustrate the roles of opposing components of selection in shaping dispersal patterns; and using genetic simulations and seascape information to create a quantitative link between empirical measures of dispersal and the resulting spatial genetic structure in the neon goby Elacatinus lori. As a whole, this work contributes to our understanding of how and why organisms have evolved to disperse through the ocean as they do.

This fellowship was established in memory of Dana Wright (CAS ’00), an alum of the BU Marine Program. After completing her studies, Wright went on to work in research in right whale acoustics at the Woods Hole Oceanographic Institution on Cape Cod.

Congratulations, E!

2023 NSF Graduate Research Fellowship Recipients and Honorable Mention

The awardees and honorable mentions for the 2023 NSF Graduate Research Fellowship Program (GRFP) competition were recently posted and several Biology students were recognized. Biology PhD student Erin Frates of the Marlow Lab, Marine Science BA student Annabel Hughes of the Davies Lab, and Biology PhD student Renata Serio of the Fiszbein Lab were awarded with 3-year graduate research fellowships. Biology PhD student Shalom Entner of the Finnerty Lab received an honorable mention.

Erin Frates is a PhD student in the Marlow Lab studying Ecology, Behavior, and Evolution. Their work is focused on environmental microbiology ranging from seafloor ecosystems to NASA ocean worlds. They are interested in understanding microbe-mineral interactions; in particular, how does microbial diversity and activity influence surrounding mineralogy, and how geochemistry in turn informs microbial ecology. Recently, Frates assessed the influence of natural and anthropogenic carbon on microbial communities at Little Sippewissett Salt Marsh on Cape Cod. Now, they are using mineral-printed electrodes to stimulate methanogenic activity under Enceladus-like conditions in order to identify potential biosignatures. Frates recently participated in a NSF-funded masterclass centered on training early career researchers to lead future deep sea expeditions.
 

Annabel Hughes graduated with a BA in Marine Science from BU in January 2023 and moved on to a Research Technician position in the Davies Lab. Her research proposal investigates three cryptic lineages in a Siderastrea siderea species complex across the Bocas del Toro Reef Complex (BTRC) in Panamá. The existence of these cryptic lineages was previously documented by Dr. Hannah Aichelman in the Davies Lab, and this additional research sets out to build upon what we already know with key information such as upper thermal limits and microbial communities of these different lineages. The overarching objective is to identify the forces influencing the spatial distributions of cryptic lineages across the BTRC seascape in an effort to understand and predict future reef responses to anthropogenic warming.

Renata Serio is a PhD student in the Fiszbein lab, which focuses on uncovering mechanisms regulating transcription and pre-mRNA processing. Her current focus, supported by the NSF GRFP, revolves around understanding the intricate mechanism behind viral protein induced alternative splicing of host genomes. Splicing is the process in which introns are removed from transcripts during pre-mRNA processing. Often, genes will have multiple alternative transcripts, this is referred to as alternative splicing. Dysregulation of alterative splicing has been identified as the cause of many cancers. During viral infection expression of specific viral proteins can alter activity of alternative splicing in host genes. This is particularly significant for a subset of viruses referred to as oncoviruses; which have the ability to induce cancer. Renata’s research combines computational and experimental approaches to unravel how viral protein expression modifies alternative splicing patterns in infected cells. 
Shalom Entner is studying variation of oxidative stress response to polystyrene (styrofoam) microplastic with ultraviolet light exposure in Nematostella vectensis using phenotypic and transcriptomic methods. Microplastics may affect organisms even when it is not ingested or incorporated into the body due to chemicals that they leach as they are exposed to UV light. Oxidants are known to leach from polystyrene, inducing oxidative stress which is likely to vary between individuals. Baseline research is needed to establish the oxidative stress responses to this exposure, especially where these toxicants may exist for extended periods of time. N. vectensis is a sentinel species in persistent salt marsh ponds that collect runoff, meaning this animal can be used as an environmental monitor. 

Congratulations to the awardees and honorable mentions on your hard work and this well-deserved honor.

Hannah Aichelman Receives 2023 Belamarich Award

By Jen CorreiaJune 27th, 2023in Grad Student News

Dr. Hannah Aichelman of the Davies Lab was selected as the winner of the 2023 Belamarich Award for her doctoral dissertation in Biology titled “Exploring Coral Symbiosis Under Climate Change Stress Across Spatial and Temporal Scales.” This award is given annually to a recent PhD candidate for their outstanding doctoral dissertation completed in the Department of Biology. The selection committee was impressed by Hannah’s deft use of diverse techniques from physiological experiments to genomics to address her research questions, which resulted in an impressive body of work already having an impact in her research community. The committee also appreciated Hannah’s extensive outreach efforts, strong mentoring record, and generous service to the Department. More information about her research is below.

Coral reefs, along with the biodiversity and communities they support, are threatened globally. While research efforts have increased our ability to understand and predict coral bleaching events, fundamental questions remain surrounding how genetic diversity of the coral symbiosis and interactions with its environment can drive resilience or resistance under climate change. Hannah's dissertation research endeavored to fill this knowledge gap, and she built a research program that combined genomics, physiology, and lab experiments to investigate stress tolerance across both temperate and tropical coral species. This research provides valuable insights into the phenotypic and genotypic mechanisms that contribute to coral success in a changing climate.

Hannah is continuing her research career at BU as a postdoctoral scholar co-advised by Dr. Sean Mullen and Dr. Sarah Davies. She is leveraging whole genome sequencing to understand the genetic underpinnings of mimicry in butterflies, while still spending some time exploring coral reefs with the Davies Lab.

As in previous years, there will be a Belamarich Award Night to celebrate our award winner. The night includes a seminar given by the awardee, a brief ceremony, and a reception. The Seminar will be held on Monday, October 30th at 4:30pm in BRB 113. The Award Ceremony will take place immediately after, with the Reception following down the hall in BRB 117, from ~5:30pm-6:30pm. We are honored to have the Belamarich family joining us again to celebrate this year’s award winner.

We look forward to seeing everyone at Belamarich Award Night!
