Emerging Investigator Series – Rebecca Whelan

Analyst is delighted to introduce our latest Emerging Investigator, Rebecca Whelan! You can read Dr Whelan’s paper, Affinity-free enrichment and mass spectrometry analysis of the ovarian cancer biomarker CA125 (MUC16) from patient-derived ascites, and find out more about her in the interview below!


Rebecca Whelan was born and raised in various small Wisconsin towns. She earned her B.A. with a double major in Chemistry and English from Lawrence University in Appleton, WI. She then moved west, joining Dick Zare’s lab at Stanford University for graduate work. Her focus there was the development of biosensor detectors for capillary electrophoresis (CE) separations. CE separations and affinity recognition remained core themes during her postdoc with Bob Kennedy at the University of Michigan and the start of her independent career at Oberlin College. Rebecca established a vigorous bioanalytical chemistry research program centered on undergraduate scholars at Oberlin and remained there for 14 years. She was excited to have the chance to relocate to the University of Notre Dame in August 2018. The Whelan lab at Notre Dame works in bioanalytical chemistry, using molecular recognition, small-scale separations, and mass spectrometry to characterize and detect ovarian cancer biomarkers.


  1. Your recent Emerging Investigator Series paper focuses on analysis of an ovarian cancer biomarker, using mass spectrometry. How has your research evolved from your first article to this most recent article?

Our first article on using mass spectrometry to analyse ovarian cancer biomarker CA125 (MUC16) was a method development paper, in which we showed the compatibility of suspension trapping with this large mucin protein (Anal Bioanal Chem, 2020, 412, 6361-6370). That study used two commercially available sources of CA125, one being a truncated variant expressed in CHO cells, and the other being full-length protein isolated from pooled human biofluids. The innovation in this most recent paper is analysing the CA125 isolated from the biofluids of individual ovarian cancer patients.

 

  1. What aspect of your work are you most excited about at the moment?

We are excited—and humbled—by the opportunity to continue working with samples from individuals with ovarian cancer. As we apply our bottom-up proteomics analysis strategy to samples derived from a larger number of individuals, we will look both for what is shared among samples and what is unique to individuals. The possibility of breaking through the current paradigm of how CA125 is detected to find a personalized CA125 signature that is detectable by mass spectrometry is very exciting to us. Such an innovation would generate new opportunities in personalized care for this serious disease. At the same time, we will continue to push the analytical performance of our method, lowering the limit of detection and improving quantitation through targeted analysis.

 

  1. In your opinion, what is the biggest advantage to using a mass spectrometry based assay, over other possible methods of analysis?

CA125 is currently detected through an immunoassay that has remain largely unchanged for decades. As with any immunoassay, what the assay really detects is an epitope, which in this case is mostly likely a discontinuous peptide sequence. Amazingly, the epitopes of CA125 have not been definitively identified (although we, and others, are actively working on that!) We wondered: what if some CA125 proteoforms in a patient’s blood happen to contain fewer epitopes, or happen to present epitopes in configurations that are not detectable by the immunoassay? Such samples would be incorrectly assessed as containing less CA125 than they actually do, which could have significant clinical implications. Mass spectrometry side-steps this dependence on epitope recognition completely.

 

  1. What do you find most challenging about your research?

CA125 (MUC16) is a challenging analyte. It’s the second-largest protein in the human body, with a variable molecular weight of 3 to 5 MDa, depending on its glycosylation. Like many other mucin proteins, it’s sticky: after all, one of its biological functions is to make mucus! In practical terms, this large size and stickiness means that if you aren’t careful, the protein will adsorb irreversibly to tips and tubes while also sticking to itself. In previous work, my group used this stickiness to advantage, performing aptamer selection inside tubes to which CA125 had adsorbed (J. Nucleic Acids, 2017, Article ID 9879135, 9 pages). For quantitation, however, the stickiness poses an obstacle that must be overcome. In addition to the analyte’s innate challenge, we work with a challenging sample matrix: crude human biofluid is our starting material. Any analyst who has tried to transition an assay from well-controlled conditions (commercially available analyte dissolved in buffer) to real-life samples knows that complexity and challenge abound in the real world. We firmly believe, however, that analytical researchers must strive to work within this complexity, because that it how real benefit to human health can be achieved.

 

  1. At which upcoming conferences or events may our readers meet you?

Naviya Schuster-Little—the graduate student who is first author on this paper—will be presenting at Pittcon 2021 in a virtual session (Tuesday, March 9, 8:30 am – 8:50 am) and would love to hear your feedback and answer your questions! I am a devoted attendee of the Midwestern Universities Analytical Chemistry Conference (MUACC) and the Gordon Research Conference on Bioanalytical Sensors, as well as Pittcon.

 

  1. How do you spend your spare time?

Music is a big part of my life. I’ve had several stints as a DJ on college radio stations in cities where I’ve lived, including Appleton, Wisconsin (WLFM) and Oberlin, Ohio (WOBC). I also love to cook (vegetarian, mostly) and go on rambles in places both familiar and unfamiliar.

 

  1. Which profession would you choose if you were not a scientist?

I’m from a family of educators and can’t imagine a life that does not involve teaching in some capacity. As an undergraduate, I completed an English major as well as a Chemistry major and edited my college’s literary magazine. After college, I seriously considered earning a PhD in 17th century English literature (I love John Donne!) or an MFA in poetry. So maybe I would be a teacher of writing or literature.

Emerging Investigator Series: Jean-Nicolas Dumez

Introducing one of our recent Emerging Investigator Series authors, Dr Jean-Nicolas Dumez! Read Dr Dumez’s recent paper ‘online reaction monitoring by single-scan 2D NMR under flow conditions,’ and find out more about him in the interview below!


Jean-Nicolas Dumez is a CNRS associate scientist at the University of Nantes, working on the developments of NMR methods for the analysis of solution mixture. He did a Ph.D. in solid-state NMR at the Ecole Normale Supérieure de Lyon in France, followed by two post-doctoral stays, working in magnetic resonance imaging, at the Weizmann Institute of Science in Israel, then in hyperpolarisation, at the University of Southampton in the UK. He joined the CNRS and moved to solution-state NMR in 2014, first in Paris-Saclay, then in Nantes. He works on the development of NMR methods, and currently focuses on the analysis of solution mixtures.


Your recent Emerging Investigator Series paper focuses on 2D NMR for online reaction monitoring. How has your research evolved from your first article to this most recent article?

I have worked in nuclear magnetic resonance (NMR) since my master’s research project, but I have moved from solids to imaging to liquids. My main interest is in the development and use of spin-dynamics tools and concepts to look at molecules. I have enjoyed moving between topics, and this paper includes ingredients collected along the way in these different areas.

What aspect of your work are you most excited about at the moment?

We are working on fast methods related to the ones described in the Analyst paper, which use diffusion information to separate the spectra of molecules in a mixture. This involves concepts that we borrow from magnetic resonance imaging (MRI), and a nice mix of theory, experiments and simulation. We are also working towards reaction monitoring with these methods.

In your opinion, what is the biggest advantage to using single-scan ultrafast 2D NMR compared to other NMR methods?

The obvious advantage is speed. For out-of-equilibrium systems (chemical reactions, hyperpolarised substrates) that evolves on a minute timescale or less, there is often no other way to collect a full 2D NMR spectrum.

What do you find most challenging about your research?

When developing NMR methods, sometimes finding the right concept is the most challenging aspect and then everything runs smoothly. Sometimes turning this concept into something that works for more than special cases is the real challenge. Both can be interesting, and I find it hard to predict in advance.   

At which upcoming conferences or events may our readers meet you?

I usually participate to magnetic resonance conferences such as EUROMAR and ENC. Hopefully the NMR community will be able meet in Asilomar next year!

How do you spend your spare time?

Most of my time outside the lab is happily spent with my family, and I occasionally still get a chance to read a few pages from a novel or listen to a recent record.

Which profession would you choose if you were not a scientist?

I have never contemplated a profession that was not science related, be it teaching, fundamental research, R & D…

Analyst is very pleased to announce the launch of our latest themed collection, focused on the topic of Biomedical Raman Imaging, guest edited by Paola Borri (Cardiff University, UK), Katsumata Fujita (Osaka University, Japan) and Analyst Advisory Board Member Wei Min (Columbia University, USA).

Paola BorriKatsumata FujitaWei Min

Raman spectroscopy has offered the potential as an optical biomedical imaging technique for many years due to the high molecular specificity, but has suffered from lack of sensitivity and the time taken for the measurements. Recent advances in instrumentation and variants on the technique such as SRS and CARS have addressed some of the limitations of the technique for biomedical imaging. This collection highlights advances in Raman spectroscopy aimed at improving the biomedical imaging capabilities and utility.

We invite submissions of articles or reviews on topics across this theme.

Accepted articles will be collated into an online collection as soon as they are accepted and the themed collection as a whole will be promoted as a complete collection in early 2021.

Emerging Investigator Series – James Blakemore

We’re very pleased to introduce our latest Emerging Investigator, James Blakemore!

Picture of James Blakemore

James Blakemore is an Assistant Professor in the Department of Chemistry at the University of Kansas. James was raised in Kansas, studied chemistry with Francis D’Souza at Wichita State University, and then moved to Yale University, completing his Ph.D. in Chemistry in 2012 as a student of Gary Brudvig and Robert Crabtree. Upon completing his Ph.D., James was a postdoctoral scholar at Caltech with Harry Gray. At KU since 2016, James’s research focuses on use of inorganic and organometallic chemistry with the d- and f-elements to gain new insights into clean energy sources.

Read James’ paper “Electrodeposition behavior of homoleptic transition metal acetonitrile complexes interrogated with piezoelectric gravimetry,” and find out more about him in the interview below.

 

 

 

 

 

 

Your recent Emerging Investigator Series paper focuses on the electrodeposition behaviour of homoleptic transition metal acetonitrile complexes. How has your research evolved from your first article to this most recent article?
Our work started by examining a nominally molecular catalyst system that seemed, under some conditions, to form electrodeposited heterogeneous material. This complicates catalyst design, and so we pursued this phenomenon, with the finding that a key homoleptic acetonitrile complex was an intermediate on the path to formation of heterogeneous material. We imagined that such acetonitrile complexes might be a more general class of electrodeposition precursors, and this idea brought us to the work laid out in our new paper.
What aspect of your work are you most excited about at the moment?
I am excited about the prospect of applying the electrochemical quartz crystal microbalance to more exotic problems in inorganic chemistry. For example, electrochemical work aimed at new processing or purification routes for lanthanide and actinide elements (those from the f-block at the bottom of the periodic table) could be quite useful. The work in our new article shows how such work might be done.

In your opinion, what are the most promising applications of piezoelectric gravimetry?
It is remarkably useful for understanding complex electrochemical systems. In molecular electrochemistry, it is often straightforward to measure currents but understanding the species present in the system giving rise to those currents can be challenging to work out. Piezoelectric gravimetry allows you to study heterogeneous species that might form and/or be present initially, or rule them out. In complex situations like those often required for studies of catalysis, this is crucial information that can totally change your view of the chemistry happening in the system.

What do you find most challenging about your research?
Research in synthetic chemistry, that is, working with compounds that we prepare ourselves rather than those found naturally, is daunting. Sometimes, even if you can design a route to make a new compound, it just won’t work. As my Ph.D. co-supervisor Bob Crabtree used to say, “Sometimes Nature is against us.” Working with a good team, however, makes these setbacks less bitter!

How do you spend your spare time?
I enjoy running, and Kansas is a great place for it; we have many beautiful hills that are gentle on your knees! I have also recently started a new dance class, which is stimulating creativity in all aspects of my life.

Which profession would you choose if you were not a scientist?
When I was an undergraduate, I wanted to become a linguist. I suppose chemistry is a sort of language, so this might not be a surprise!

Can you share one piece of career-related advice or wisdom with other early career scientists?
One of the great pleasures for me during my time as an early-career scientist has been networking and meeting scientists from many different communities. As a postdoctoral scholar or graduate student, you may work in a narrower area, but as a faculty member, I have had the opportunity to meet a wide range of individuals with many different perspectives. I would advise early career scientists to embrace these opportunities, and the diversity of viewpoints that there are in the world. There are so many kind and supportive people to meet!
