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 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

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
![Page 11: Researching with the Big Guys: Community Colleges and Cancer Research](https://reader036.fdocuments.net/reader036/viewer/2022070405/56813feb550346895daae960/html5/thumbnails/11.jpg)

Training Students for Cancer Research
1.Detecting causes of cancer
2.Detecting biomarkers for cancer of different origins
3.Improving cancer therapy regimen
![Page 18: Researching with the Big Guys: Community Colleges and Cancer Research](https://reader036.fdocuments.net/reader036/viewer/2022070405/56813feb550346895daae960/html5/thumbnails/18.jpg)
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?
![Page 19: Researching with the Big Guys: Community Colleges and Cancer Research](https://reader036.fdocuments.net/reader036/viewer/2022070405/56813feb550346895daae960/html5/thumbnails/19.jpg)
1. DNA in the nucleus is organized via chromosomes
2. Chromosomal aberrations were found to be the biomarker for cancer in unexposed cohorts
