Establishing a human renal cell carcinoma tumorgraft platform for preclinical drug testing

Abstract: SUMMARY Traditionally, xenograft models have been used to study tumors in vivo. However, their utility is reduced by the use of tumor cell lines for implantation. Tumorgrafts (TGs; also known as patient-derived xenografts (PDX)), which involve patient-derived tumor samples, are increasingly recognized as more representative models than traditional xenografts. Furthermore, we showed previously that renal cell carcinoma (RCC) TGs retain the histology, gene expression, DNA copy number alterations, mutations, and … Show more

“…HIF-2, a transcription factor, has been regarded as undruggable 11 . A structure-based design approach identified a selective HIF-2 antagonist (PT2399) that we evaluate using a tumorgraft (TG)/PDX platform 12,13 . PT2399 dissociated HIF-2 (an obligatory heterodimer [HIF-2α/HIF-1β]) 14 in human ccRCC suppressing tumorigenesis in 56% (10/18) lines.…”

“…Při tomto procesu je bezpodmínečně nutná sterilita vná-šené tkáně [69]. Nádorové buňky nebo kousky tkáně bývají často před vlastní injikací do myši smíchány s Matrigelem, který zefektivní růst xenogenního ná-doru a přispívá k udržení původního fenotypu nádoru.…”

“…Xenograft tumours are Page 9 of 44 A c c e p t e d M a n u s c r i p t formed by subcutaneously injecting tumour cells in an anatomically suitable site (e.g., mammary fat pad) of immunocompromised mice. Subcutaneous tumours are more befitting for performing drug trials owing to their ability to allow accurate drug efficacy measurement by evaluation of tumour size over time [71]. The rate of tumour development depends on the cancer type, cell origin and cell line used.…”
