Clinically relevant orthotopic pancreatic cancer models for adoptive T cell transfer therapy by Gregory B. Lesinski, Chrystal M. Paulos, Maggie Phillips, Jacklyn Hammons, Isaac Karpovsky, Zaid Mahdi, Natalie K. Horvat, Megan M. Wyatt, Margaret A. Hall, Cameron J. Herting, Richard A. Moffitt

“…However, these models have limitations, including marked tumor variability across individual mice and the cost of colony maintenance.Methods Using flow cytometry and immunohistochemistry, we characterized the immunological features and trafficking patterns of adoptively transferred T cells in orthotopic PDAC (C57BL/6) models using two mouse cell lines, KPC-Luc and MT-5, isolated from C57BL/6 KPC-GEMM (KrasLSL-G12D/+p53−/− and KrasLSL-G12D/+p53LSL-R172H/+, respectively).Results The MT-5 orthotopic model best recapitulates the cellular and stromal features of the TME in the PDAC GEMM. …”

Role of Epstein-Barr Virus and Human Papilloma Virus in the Development of Oropharyngeal Cancer: A Literature Review by Michela Migliaro, Daniela Massuh, María Fernanda Infante, Ana María Brahm, María Trinidad San Martín, Duniel Ortuño

“…It was found that, among the carcinogenic mechanisms of HPV, E6 and E7 proteins are responsible for the malignization process, inhibiting tumor suppressors p53 and pRb. As to EBV, it was noted that its “hit and run” phenomenon manipulates the host epigenetic mechanism, triggering the tumor process without the virus being currently present; a “cellular reprogramming” is essentially generated, causing heritable changes in gene expression without DNA mutation. …”
