[PDF][PDF] Glioma progression is shaped by genetic evolution and microenvironment interactions

FS Varn, KC Johnson, J Martinek, JT Huse… - Cell, 2022 - cell.com
The factors driving therapy resistance in diffuse glioma remain poorly understood. To
identify treatment-associated cellular and genetic changes, we analyzed RNA and/or DNA …

Longitudinal molecular trajectories of diffuse glioma in adults

FP Barthel, KC Johnson, FS Varn, AD Moskalik… - Nature, 2019 - nature.com
The evolutionary processes that drive universal therapeutic resistance in adult patients with
diffuse glioma remain unclear 1 , 2 . Here we analysed temporally separated DNA-…

Radiotherapy is associated with a deletion signature that contributes to poor outcomes in patients with cancer

E Kocakavuk, KJ Anderson, FS Varn, KC Johnson… - Nature …, 2021 - nature.com
Ionizing radiation causes DNA damage and is a mainstay for cancer treatment, but
understanding of its genomic impact is limited. We analyzed mutational spectra following …

Single-cell multimodal glioma analyses identify epigenetic regulators of cellular plasticity and environmental stress response

…, ET Courtois, AD Gujar, FP Barthel, FS Varn… - Nature …, 2021 - nature.com
Glioma intratumoral heterogeneity enables adaptation to challenging microenvironments
and contributes to therapeutic resistance. We integrated 914 single-cell DNA methylomes, …

Immunoregulatory functions of VISTA

Utilization of negative checkpoint regulators ( NCR s) for cancer immunotherapy has garnered
significant interest with the completion of clinical trials demonstrating efficacy. While the …

[HTML][HTML] Perspective of mesenchymal transformation in glioblastoma

Y Kim, FS Varn, SH Park, BW Yoon, HR Park… - Acta neuropathologica …, 2021 - Springer
Despite aggressive multimodal treatment, glioblastoma (GBM), a grade IV primary brain
tumor, still portends a poor prognosis with a median overall survival of 12–16 months. The …

[HTML][HTML] Very low mutation burden is a feature of inflamed recurrent glioblastomas responsive to cancer immunotherapy

…, Y He, A Desjardins, JE Herndon, FS Varn… - Nature …, 2021 - nature.com
Several immunotherapy clinical trials in recurrent glioblastoma have reported long-term
survival benefits in 10–20% of patients. Here we perform genomic analysis of tumor tissue from …

Hypoxia-induced VISTA promotes the suppressive function of myeloid-derived suppressor cells in the tumor microenvironment

…, R Manivanh, I Le Mercier, CH Lowrey, FS Varn… - Cancer immunology …, 2019 - AACR
Tumor hypoxia is a negative prognostic factor that is implicated in oncogenic signal activation,
immune escape, and resistance to treatment. Identifying the mechanistic role of hypoxia in …

Systematic pan-cancer analysis reveals immune cell interactions in the tumor microenvironment

FS Varn, Y Wang, DW Mullins, S Fiering, C Cheng - Cancer research, 2017 - AACR
With the recent advent of immunotherapy, there is a critical need to understand immune cell
interactions in the tumor microenvironment in both pan-cancer and tissue-specific contexts. …
