Mechanistic Dissection of Protein Disposal Machineries

Academic Division:

Biological Sciences

Academic Department:

Cell and Developmental Biology

Description:

A post-doctoral position is available in the newly-established laboratory of Prof. Sonya Neal at the Division of Biological Sciences of University of California San Diego (UCSD). We perform structural and biochemical analyses on cellular machineries involved in protein quality control through the ER-associated protein degradation (ERAD) pathway. ERAD is responsible for handling misfolded protein and protein assemblies to the cytosolic proteasome for degradation, a process that if impaired is strongly linked to neurodegenerative and protein misfolding diseases. We are using biochemistry, lipidomics, cell biology, and genetics to understand how rhomboid pseudoproteases remove multi-spanning membrane proteins from the ER lipid bilayer for targeted degradation by the cytosolic 26S proteasome. Studies will employ state-of-the-art tools for in vivo and in vitro manipulation of ERAD that has been developed by Dr. Neal (Molecular Cell, 2018).

Inflammatory Tumor Microenvironment and Its Impact on Cancer Development

Academic Division:

Biological Sciences

Academic Department/Research Unit:

Molecular Biology

Description:

The Lauberth laboratory in the Division of Biological Sciences at the University of California San Diego welcomes applications for research positions at the postdoctoral level. The primary goal of the research in our laboratory is to study perturbations in gene regulation that lead to the development of human cancer. The open positions will focus on investigating the mechanisms that link the cancer-promoting effects of inflammation to genetic aberrations in the p53 gene, which are the most frequent alterations in human cancer. Using the stimulus-induced expression of inflammatory genes in human cancer cells as a model, the Lauberth lab has made important contributions in revealing mechanistic insights into how immune signaling drives alterations in the cancer cell transcriptome. Specifically, we have demonstrated a functional crosstalk between mutant p53 and the master proinflammatory regulator NFkB that shapes an active enhancer landscape to reprogram the cancer cell transcriptome in response to chronic TNFa signaling. These findings that have significant implications for understanding how p53 mutants impart transcriptional plasticity to a tumor in response to chronic immune signaling were published in Nature Communications 2017. To build upon these findings, the open positions will include leveraging mouse models and single-cell sequencing analyses to further explore the mechanisms underlying the roles of inflammatory cytokines in signaling between tumor and immune cells in the tumor microenvironment and to dissect the role of p53 mutants in modulating the composition and functions of the cell populations within a single tumor.

Applicant Requirements:

Candidates must have a strong background in biochemistry, molecular biology, and/or genomics and a first-author publication. The research will combine cell and molecular biology techniques, cell-free biochemical assays, and Next-Gen sequencing (ie. ChIP-seq, GRO-seq, ATAC-seq). We particularly value motivated, creative, and collaborative team members.

How to apply:

Interested applicants should send their cover letter containing a summary of their prior work and a short paragraph describing research interests and career plans, curriculum vitae, and the names of three references to Shannon Lauberth, PhD at slauberth@ucsd.edu.

Noncoding RNAs in Human Cancer

Academic Division:

Biological Sciences

Academic Department/Research Unit:

Molecular Biology

Description:

The Lauberth laboratory in the Division of Biological Sciences at the University of California San Diego welcomes applications for research positions at the postdoctoral level. The primary goal of the research in our laboratory is to study perturbations in gene regulation that lead to the development of human cancer. The open positions will focus on investigating the roles of noncoding enhancer RNAs (eRNAs) in human cancers that contain genetic alterations in p53, which are present in more than 50% of all human cancers. The recent and intriguing discovery that enhancers support transcription has raised a key question of whether eRNAs are functional molecules, or merely reflections of enhancer activation and thereby transcriptional noise. This question has gained considerable traction due to a number of recent studies that have started to unveil functions for at least a subset of eRNAs. We recently identified a class of enhancers that support eRNA production in a manner that is dependent on mutant p53 (Nature Communications 2017). The open positions will include research that is aimed to identify and characterize the functions of these eRNAs in gene regulation and cancer development. Also, the position will include exploring the feasibility of targeting this class of eRNAs as a means of silencing cancer-causing genes as a transformative approach in cancer treatment. These studies are of great significance, given the emerging field of functional eRNAs and the potential of using eRNAs as diagnostic markers and therapeutic targets for altering enhancer activities that are linked to human disease.

Applicant Requirements:

Candidates must have a strong background in biochemistry, molecular biology, and/or genomics and a first-author publication. The research will combine cell and molecular biology techniques, cell-free biochemical assays, and Next-Gen sequencing (ie. ChIP-seq, GRO-seq, ATAC-seq). We particularly value motivated, creative, and collaborative team members.

How to apply:

Interested applicants should send their cover letter containing a summary of their prior work and a short paragraph describing research interests and career plans, curriculum vitae, and the names of three references to Shannon Lauberth, PhD at slauberth@ucsd.edu.
