Presentation Overview

  • The Cost of Cancer Research

  • Community College Cancer Research Activity

  • CNAQ Cancer Research – Origins and Development

  • Training Students for Cancer Research

  • Future Plans


The cost of cancer research

The Cost of Cancer Research

  • Cancer research is expensive

    • Personnel (scientists, oncologist, radiologists

    • Equipment (microscopy, MRIs, shipment costs!)

    • Infrastructure (research complexes, compliance)

    • Drug development and patenting


Cancer microscopy

Cancer research infrastructure

German Cancer Research Centre

M.D. Anderson Cancer Center


Cancer drug development

Cancer Drug Development

  • Average cost of R&D to bring one cancer drug to market: $802 million

  • Risk!!!

    • Only 1 in 1000 new compounds make it to human trials testing

    • Of those, only 1 in 5 receive FDA approval


Community college cancer research activity

Community College Cancer Research Activity

  • St. Vincent and the Grenadines Community College (Caribbean)

  • Aroka Ramsey Community College (Minnesota)

  • Capital Community College (Connecticut)

Community College Cancer Research Activity

  • Other Initiatives

    • CIHR Community College Innovation Program (Canada)

    • Community College Undergraduate Research Initiative (CCURI) www.ccuri.org (US)

    • NIH’s Community College Summer Enrichment Program (US)

    • QNRF (UREP Program) in Qatar


Cnaq cancer research origins and development

CNAQ Cancer Research – Origins and Development

  • Research Environment in Qatar is unique. National Priorities tied to research in order to diversify from a carbon economy.

    • well resourced financially (2.8% GDP)

    • QNRF

    • But …

      • Little data

      • Few grads, post docs

      • Lab spaces, equipment, technicians in early stages

      • Top-down research model vs lateral or bottom-up


Cnaq resources

CNAQ Resources

  • Support – Executive, Deans, Lab Managers, Facilities, Procurement

  • Faculty and Students - enthusiastic

Training students for cancer research

Training Students for Cancer Research

  • Detecting causes of cancer

  • Detecting biomarkers for cancer of different origins

  • Improving cancer therapy regimen


Training students for cancer research1

Training Students for Cancer Research

Training is mainly implemented by organizing different workshops on cellular and molecular biology assays in order to explore the effect of physical and chemical agents on human DNA by analysing chromosomal alterations. WHY?


Researching with the big guys community colleges and cancer research

1. DNA in the nucleus is organized via chromosomes

2. Chromosomal aberrations were found to be the biomarker for cancer in unexposed cohorts

Biological Cytogenetic Assays for Assessing genotoxic potential of physical and chemical agents in mammalian cells

  • Dicentrics

  • (in metaphases)

2. Micronuclei (in binucleated cells)

3. Premature Chromosome Condensation (PCC) (in interphases)

4. Translocations using Fluorescence in situ hybridization (FISH)(in metaphases)
