Challenges to curing primary brain tumours.
Aldape, K; Brindle, KM; Chesler, L; Chopra, R; Gajjar, A; et al. (NATURE PUBLISHING GROUP, 2019-08-01)Despite decades of research, brain tumours remain among the deadliest of all forms of cancer. The ability of these tumours to resist almost all conventional and novel treatments relates, in part, to the unique cell-intrinsic ... -
HSF1 Is Essential for Myeloma Cell Survival and A Promising Therapeutic Target.
Fok, JHL; Hedayat, S; Zhang, L; Aronson, LI; Mirabella, F; et al. (AMER ASSOC CANCER RESEARCH, 2018-05-15)Purpose: Myeloma is a plasma cell malignancy characterized by the overproduction of immunoglobulin, and is therefore susceptible to therapies targeting protein homeostasis. We hypothesized that heat shock factor 1 (HSF1) ... -
Inhibition of mTOR-kinase destabilizes MYCN and is a potential therapy for MYCN-dependent tumors.
Vaughan, L; Clarke, PA; Barker, K; Chanthery, Y; Gustafson, CW; et al. (IMPACT JOURNALS LLC, 2016-09-06)MYC oncoproteins deliver a potent oncogenic stimulus in several human cancers, making them major targets for drug development, but efforts to deliver clinically practical therapeutics have not yet been realized. In childhood ... -
MIR21 Drives Resistance to Heat Shock Protein 90 Inhibition in Cholangiocarcinoma.
Lampis, A; Carotenuto, P; Vlachogiannis, G; Cascione, L; Hedayat, S; et al. (W B SAUNDERS CO-ELSEVIER INC, 2018-03-01)BACKGROUND & AIMS: Cholangiocarcinomas (CCA) are resistant to chemotherapy, so new therapeutic agents are needed. We performed a screen to identify small-molecule compounds that are active against CCAs. Levels of microRNA ... -
Modulation of Biliary Cancer Chemo-Resistance Through MicroRNA-Mediated Rewiring of the Expansion of CD133+ Cells.
Carotenuto, P; Hedayat, S; Fassan, M; Cardinale, V; Lampis, A; et al. (LIPPINCOTT WILLIAMS & WILKINS, 2020-09-10)BACKGROUND AND AIMS: Changes in single microRNA (miRNA) expression have been associated with chemo-resistance in biliary tract cancers (BTCs). However, a global assessment of the dynamic role of the microRNome has never ... -
Modulation of pancreatic cancer cell sensitivity to FOLFIRINOX through microRNA-mediated regulation of DNA damage.
Carotenuto, P; Amato, F; Lampis, A; Rae, C; Hedayat, S; et al. (NATURE PORTFOLIO, 2021-11-18)FOLFIRINOX, a combination of chemotherapy drugs (Fluorouracil, Oxaliplatin, Irinotecan -FOI), provides the best clinical benefit in pancreatic ductal adenocarcinoma (PDAC) patients. In this study we explore the role of ... -
Orally bioavailable CDK9/2 inhibitor shows mechanism-based therapeutic potential in MYCN-driven neuroblastoma.
Poon, E; Liang, T; Jamin, Y; Walz, S; Kwok, C; et al. (AMER SOC CLINICAL INVESTIGATION INC, 2020-11-02)The undruggable nature of oncogenic Myc transcription factors poses a therapeutic challenge in neuroblastoma, a pediatric cancer in which MYCN amplification is strongly associated with unfavorable outcome. Here, we show ... -
Overexpression of EZH2 in multiple myeloma is associated with poor prognosis and dysregulation of cell cycle control.
Pawlyn, C; Bright, MD; Buros, AF; Stein, CK; Walters, Z; et al. (SPRINGERNATURE, 2017-03-31)Myeloma is heterogeneous at the molecular level with subgroups of patients characterised by features of epigenetic dysregulation. Outcomes for myeloma patients have improved over the past few decades except for molecularly ... -
Patient-derived organoids model treatment response of metastatic gastrointestinal cancers.
Vlachogiannis, G; Hedayat, S; Vatsiou, A; Jamin, Y; Fernández-Mateos, J; et al. (AMER ASSOC ADVANCEMENT SCIENCE, 2018-02-23)Patient-derived organoids (PDOs) have recently emerged as robust preclinical models; however, their potential to predict clinical outcomes in patients has remained unclear. We report on a living biobank of PDOs from ... -
Pediatric and adult glioblastoma radiosensitization induced by PI3K/mTOR inhibition causes early metabolic alterations detected by nuclear magnetic resonance spectroscopy.
Agliano, A; Balarajah, G; Ciobota, DM; Sidhu, J; Clarke, PA; et al. (IMPACT JOURNALS LLC, 2017-07-18)Poor outcome for patients with glioblastomas is often associated with radioresistance. PI3K/mTOR pathway deregulation has been correlated with radioresistance; therefore, PI3K/mTOR inhibition could render tumors radiosensitive. ... -
Second-Generation HSP90 Inhibitor Onalespib Blocks mRNA Splicing of Androgen Receptor Variant 7 in Prostate Cancer Cells.
Ferraldeschi, R; Welti, J; Powers, MV; Yuan, W; Smyth, T; et al. (AMER ASSOC CANCER RESEARCH, 2016-05-01)Resistance to available hormone therapies in prostate cancer has been associated with alternative splicing of androgen receptor (AR) and specifically, the expression of truncated and constitutively active AR variant 7 ... -
Wnt signalling modulates transcribed-ultraconserved regions in hepatobiliary cancers.
Carotenuto, P; Fassan, M; Pandolfo, R; Lampis, A; Vicentini, C; et al. (BMJ PUBLISHING GROUP, 2016-09-14)OBJECTIVE: Transcribed-ultraconserved regions (T-UCR) are long non-coding RNAs which are conserved across species and are involved in carcinogenesis. We studied T-UCRs downstream of the Wnt/β-catenin pathway in liver cancer. ...
