A postdoctoral research position is available starting January 1, 2023, in the laboratory of Dr. Dawn Quelle. The lab investigates druggable mechanisms driving neuroendocrine tumor and sarcoma pathogenesis with the goal of developing more effective therapies for patients with those cancers. This NIH R01 funded position seeks to define the role of RABL6A-PP2A signaling in neuroendocrine tumor progression, metastasis and response to targeted therapy. Studies include analyses of human tumor specimens for pathway alterations as well as molecular and cell biological analyses in cancer derived cells testing how each factor affects cell biology and drug responsiveness. In vivo studies employ novel genetic knockout/transgenic mice and xenograft mouse models enabling bioluminescence imaging of tumors. The lab is tightly affiliated with the University of Iowa’s NCI designated Holden Comprehensive Cancer Center, uses exceptional core research facilities, and collaborates extensively with clinical colleagues in surgical oncology, genetics, medical oncology, imaging and pathology.
Requirements: A motivated individual with a Ph.D. in biomedical sciences is required. Practical experience with mammalian cell culture, molecular biology, analyses of cell signaling pathways, tumor immunology and/or drug response studies is highly desired. Must be willing to work with mice, prior experience is preferred.
The University of Iowa is located in Iowa City, Iowa, a fun, safe, mid-sized college town in the Midwest of the United States with high living standards and an inexpensive cost of living relative to larger cities.

Location: CCSR 2255-A, 1291 Welch Rd., Stanford, CA 94305-5165
Project: Advancing a mouse model of SDHB hereditary pheochromocytoma and paraganglioma (hPPGL).
Brief Summary: The goals of this project are (1) to understand the molecular mechanism of SDHB-deficient PPGL tumorigenesis and (2) to develop therapeutic leads for the treatment of SDHx tumors. This work will leverage the recently generated SDHB PPGL mouse model that has been generated in the lab and the laboratory’s expertise in chemical screening and drug development. The project is supported by a full-time medicinal chemist to enable novel therapeutic development. Competitive post-doctoral candidates should be highly motivated, interested/experienced in animal disease models and interested in therapeutic identification/development.
Position availability: Immediately

We have open positions in the lab for postdoctoral fellows who are interested in working on spatial and systems oncology applied to GI malignancies, with a particular focus on pancreatic ductal adenocarcinoma and pancreatic neuroendocrine tumors. The Hwang lab is focused on studying tumor-stroma interactions at unprecedented resolution through the development and application of techniques in single-cell and spatial biology, multiplexed imaging, and functional genetic screens to patient-derived specimens, organoids, and mouse models to elucidate mechanisms of (1) therapeutic resistance mediated by genetic, epigenetic, and phenotypic factors including cell state plasticity; (2) treatment-mediated remodeling of the spatial microarchitecture of tumors and underlying cancer cell-stromal interactions; and (3) tumor-nerve crosstalk, which plays a critical role in the pathophysiology and morbidity of many malignancies but remains understudied.

Our lab combines cutting edge experimental techniques with big-data analytical approaches to study how genetic and epigenetic alterations of regulatory DNA elements drive cancer. We are recruiting post-doctoral researchers and PhD students that will either focus mostly on the experiential and biological aspects, the computational analysis, or wish to combine both. We focus on two types of regulatory DNA elements: enhancers (regulating transcription), and CTCF binding sites (regulating chromosomal topology, i.e. the folding of the chromosome in 3D).
Intratumoral and intertumoral regulatory heterogeneity
We develop systematic approaches to integrate genetic, epigenetic, topologic and transcriptional information to study how epigenetic alterations affect cis regulatory DNA elements, and their variation between tumors and between the different cancer cells within each tumor. For example,
we have recently uncovered different regulatory and developmental subtypes of pancreatic neuroendocrine tumors [1], and paracrine interactions between different cell types that constitute adenoid cystic carcinomas [2]. We are now extending these efforts to study lung neuroendocrine tumors and hepatocellular carcinomas.
Tumorigenic epigenetic topological alterations
We have previously demonstrated that aberrant DNA methylation of CTCF binding sites in IDH-mutant glioma [1] and SDH deficient gastrointestinal stromal tumors [2] perturbs chromosomal topology. In these tumors, accumulation of DNA methylation at the boundary between two topological domains inhibits CTCF binding and disrupts the insulation between the domains. This leads to aberrant interactions between an oncogene in one domain and enhancers in the other, leading to over-expression of the oncogene. This groundbreaking model links metabolic, epigenetic and topological alterations and demonstrates how they can drive cancer. We are now extending this framework to additional types of cancer including SDH deficient pheochromocytoma and IDH mutant cholangiocarcinoma to study the basic principles of epigenetic topologic alterations, and to uncover drivers and sensitivities of pheochromocytoma and cholangiocarcinoma.\
Position start date is flexible.

The Dayton lab at EMBL Barcelona is recruiting postdoctoral researchers interested in dissecting the mechanisms of tumor initiation and progression in pulmonary neuroendocrine cancers.
The Dayton lab develops 3D in vitro organoid models of human tissue to recapitulate developmental and cancer phenotypes of pulmonary neuroendocrine cells. The group has two broad areas of interest – development and cancer – and we want to understand how these intersect and can be manipulated for patient benefit.
We also develop patient derived tumor organoid models of pulmonary neuroendocrine tumors and of large cell neuroendocrine carcinoma, for mechanistic studies aimed at understanding tumor progression, tumor evolution, and drug response. More information about the lab can be found on their website: https://www.embl.org/groups/dayton/.
Dr. Dayton aims to create an inclusive & fun team environment where team members support and inspire each other so that they can solve problems and address important questions together. Dr. Dayton is committed to supporting the career development of her team members.
Interested candidates can submit a cover letter and their CV to Talya Dayton, PhD (talya.dayton@embl.es)
