Postdoc Fellow - Head & Neck Surgery (Osman Lab)
- Requisition #: 600382-202401121250
- Department: Head & Neck Surgery - Research
- Location: Houston, TX
- Posted Date: 1/12/2024
We are seeking talented and motivated applicants with recent PhD or MD/PhD experience in Cancer Biology/Biochemistry/Molecular Biology to study the emergence and mechanism of resistance to cisplatin and molecularly targeted therapy in head and neck cancer cells harboring mutant TP53 and HPV infection in the department of Head & Neck Surgery- Research. The research involves studies on; a) novel in vitro and in vivo targeting of DNA repair and genomic instability-induced replication stress mechanisms for maximizing response to chemotherapy, radiotherapy, and immunotherapy; b) understanding the mechanisms and impact of oncogenic mutant TP53 and HPV-oncoproteins on tumor immune microenvironment (TIME); c) examining the mechanistic role of KEAP1-NRF2-CUL3 pathway dysregulation in cisplatin resistance and metastasis.
LEARNING OBJECTIVES
The objectives of her project are a) To target DNA repair and replication stress mechanisms for maximizing response to chemotherapy, radiotherapy and immunotherapy; b) To understand the mechanisms and impact of oncogenic mutant TP53 and HPV-oncoproteins on tumor immune microenvironment (TIME); c) To examine the mechanistic role of KEAP1-NRF2-CUL3 pathway dysregulation in cisplatin resistance and metastasis. To achieve these objectives, the candidate will utilize collection of head and neck tumor cell lines and PDX models combined with various in vitro techniques involving DNA cloning, tissue culture, western blotting, immunostaining, CRISPR/Cas9 related technologies along with generation of stable cell line models. The in vitro studies will be extended in vivo to test pharmacological drugs such as WEE1, ATR, Rad51 and CHK1 inhibitors that target replication stress and genomic instability in HNSCC using our established preclinical oral cancer models. These studies will be followed by unbiased sequencing and epigenetic platforms including RNA seq, scRNA and scATAC sequencing on tumors obtained from mice following treatment with the drugs, and in some instance from head and neck patients who failed standard of care-treatment. Working along with our bioinformatician collaborators at our Institution, the candidate will be involved in the analyses of the results obtained from the sequencing and will conduct correlative outcome studies on the head and neck TCGA data sets available in cBioPortal for Cancer Genomics.
ELIGIBILITY REQUIREMENTS
The candidate will work with cutting edge approaches consists of multi-omic strategies and techniques involving DNA cloning, tissue culture, immunostaining, CRISPR/Cas9 gene editing along with generation of stable cell line models, mouse, and human tumor studies. The successful candidate will integrate and work with multidisciplinary teams of bioinformaticians, molecular biologists, and clinicians.
