Clinical Pharmacology & Experimental Therapeutics Center

The center provides pharmaceutical expertise to conduct and support preclinical and clinical/translational trials, and postmarketing assessment of pharmaceutical drugs. The Clinical Pharmacology & Experimental Therapeutics Center consists of three core areas of focused research:

  • North Texas Clinical Pharmacology Cancer Core (funded in part by the Cancer Prevention and Research Institute of Texas)
  • Regulatory Sciences Core
  • Experimental Therapeutics and Diagnostics Core: has preclinical resources for researchers and collaborators to develop and test new drugs and enable translational research in drug discovery/development. Our cell disease models in cancer and neurodegeneration diseases are designed for drug screening, new therapeutic target exploring, as well as drug tolerability and efficacy studies. With our advanced instrumentation, that includes three advanced mass spectrometry with established proteomics, metabolomics and epigenetics workflow, we are striving to discover new diagnostics biomarkers of cancer and neurodegeneration diseases with our clinic collaborators.

 

The Center's analytical laboratory specializes in developing and validating methods for the analysis of both small- and large-molecule pharmaceutical agents, their metabolites, and biomarkers in complex biologic matrices using state-of-the-art bioanalytical techniques.

SCIEX 7500 is a QTRAP Triple Quad system featured with MRM3 QTRAP scan and an enhanced product ion (EPI) scan. Those are effective scan solutions that removes high background and interferences and can achieve lower detection limits compared to most existing triple quad systems. Especially with MRM3 scans, it offers better specificity and quantitative performance for drug metabolites that share similar structure or similar mass of fragment ions.

SCIEX ZenoTOF 7600 is a Q-TOF instrument equipped with a hybrid collision cell. The collision cell includes two collision modes -collision induced dissociation (CID) and electron activated dissociation (EAD). EAD (radical) and CID (thermal) collision could produce invaluable complimentary fragmentation maps that significantly increase the identification rate for biomolecule structures.

ZenoTOF 7600 is also a great tool to explore intact proteins with its build-in peak deconvolution software. With the ability to look at the intact proteins, we are easily on the path to explore protein posttranslational modifications and protein-protein interactions.

SCIEX 6500 QTRAP is a traditional Triple Quad system. QTRAP means the third quadrupole can be configured as a Linear Ion Trap (LIT) to provide simultaneous quantitation and identification without losing the sensitivity.

Our SCIEX 6500 is coupled with a differential ion mobility mass spectrometry SelexION, which provides the unique capability to separate analytes with identical molecular weights and retention times.

Leica Laser LDM6 Microdissection Microscopes is a contact- and contamination-free method for isolating specific single cells or an area of tissue. This tool allows us to study the biochemical heterogeneity within a tumor or among cells. It captures the spatial profile of quantitative analysis. It also enables single cell metabolomics or proteomics study for cancer as well as other diseases.
