Zoey's second paper is now online at Cell Death Discovery! She studied how a GLUT1 inhibitor causes apoptosis in head and neck cancer cells. At lower concentrations, this GLUT1 inhibitor also sensitizes cancer cells to bitter taste receptor agonists to enhance their apoptotic effects. Great work Zoey! Another important contributor to this work (and second author!) was our Penn IDEAL SUIP student Sahil Muthuswami. You can read the open access (freely available) paper online here.

Zoey wins Blavatnik Fellowship
We're very proud that Penn Pharmacology grad student Zoey Miller from our lab was just awarded a prestigious Blavatnik Family Fellowship, generously sponsored by The Blavatnik Family Foundation, which will support her to work on T2R bitter receptors in HNSCCs over the coming academic year. Congratulations Zoey! This is one of the most prestigious awards given to Penn Biomedical Graduate Studies students. We are very grateful for generosity of Blavatnik Family Foundation supporting these awards, and very grateful they also saw what we already knew: that Zoey was incredibly deserving of the award. Great job!

AChemS 2023
Zoey and Rob represented the lab at the 2023 AChemS meeting in Florida. It was great to catch up with colleagues and learn about lots of new exciting taste research! Zoey's poster was very well attended (there was a line) and Rob got some great questions after his talk. All in all, it was a successful trip!

Postdoc Openings
Our lab is located within the Division of Rhinology in the Department or Otorhinolaryngology. More about our lab’s research, equipment and resources, and recent publications by students and postdocs, can be found at www.robleelab.com
The postdoc will work closely with the PI and other lab members and receive training in live-cell imaging and other techniques as needed, potentially including measurements of calcium, nitric oxide, pH, ciliary beat frequency, fluid secretion, phagocytosis, and/or imaging of fluorescent protein biosensors. The postdoc will also be expected to independently or collaboratively develop or learn new techniques as required by the project. Opportunities for professional development (grant writing, review writing, collaborations, conferences, etc.) will be encouraged and supported. Salary and benefit information (based on NIH NRSA stipend levels) and information about postdoctoral policies at Penn are outlined on the Biomedical Postdoctoral Programs website.
A PhD in a biological science (cell biology, molecular biology, immunology, physiology, etc.), with demonstration of successful completion of thesis project. Experience in cell culture, biochemistry, and/or imaging is highly desirable, but not required. Communication skills (reading, writing, speaking), enthusiasm, and good interpersonal skills are essential. We encourage individuals from underrepresented racial and ethnic groups, and individuals from socially, culturally, economically, or educationally disadvantaged backgrounds to apply.
Please email a cover letter and CV, including publications and the names of three references, to Rob (rjl [at] pennmedicine [dot] upenn [dot] edu).

New paper online at Nutrients
In a nutshell, NPY may be elevated in the airways in sinus diseases or in asthma. NPY is also one of few negative regulators of airway cilia beating (via NPY2R receptors and PKC). This paper shows the same NPY2R/PKC pathway reduces cilia bitter receptor NO, linking NPY with impaired innate defense.
Airway neuropeptides (NPY, VIP, SubP, etc.) have diverse effects via GPCRs on airway epithelial & immune cells. While likely important for airway physiology & pathophysiology, we still don't know enough about how they influence these cells. Because T2R bitter receptor signaling to eNOS and production of NO controls other responses (like macrophage phagocytosis), NPY (or related PP or PYY) may also reduce T2R-mediated responses in other tissues (but likely depends on NPYRs expressed there). How do other neuropeptides regulate T2R responses in the airway? Stay tuned.

Congrats Zoey!
Congratulations to Zoey on an excellent PGG post-rotation talk to end her first year of grad school. That's a huge accomplishment in normal times let alone a pandemic. Way to go, Zoey!
