[HTML][HTML] Combining PARP with ATR inhibition overcomes PARP inhibitor and platinum resistance in ovarian cancer models

…, R Zhang, VE Velculescu, EJ Brown, F Simpkins - Nature …, 2020 - nature.com
Ovarian cancer (OVCA) inevitably acquires resistance to platinum chemotherapy and PARP
inhibitors (PARPi). We show that acquisition of PARPi-resistance is accompanied by …

Targeting the ATR/CHK1 Axis with PARP Inhibition Results in Tumor Regression in BRCA-Mutant Ovarian Cancer Models

…, MA Morgan, M Herlyn, EJ Brown, F Simpkins - Clinical Cancer …, 2017 - AACR
Purpose: PARP inhibition (PARPi) has modest clinical activity in recurrent BRCA-mutant (BRCA
MUT ) high-grade serous ovarian cancers (HGSOC). We hypothesized that PARPi …

Radiation therapy compared with pelvic node resection for node-positive vulvar cancer: a randomized controlled trial

C Kunos, F Simpkins, H Gibbons, C Tian… - Obstetrics & …, 2009 - journals.lww.com
OBJECTIVES: To report long-term survival and toxicity of radiation compared with pelvic node
resection for patients with groin node–positive vulvar cancer. METHODS: A Gynecologic …

[PDF][PDF] BET bromodomain inhibition synergizes with PARP inhibitor in epithelial ovarian cancer

…, N Fatkhutdinov, AV Kossenkov, AJ Wilson, F Simpkins… - Cell reports, 2017 - cell.com
PARP inhibition is known to be an effective clinical strategy in BRCA mutant cancers, but PARP
inhibition has not been applied to BRCA-proficient tumors. Here, we show the synergy of …

[HTML][HTML] Combination ATR and PARP Inhibitor (CAPRI): A phase 2 study of ceralasertib plus olaparib in patients with recurrent, platinum-resistant epithelial ovarian …

…, DA Torigian, WT Hwang, R Giuntoli, F Simpkins - Gynecologic …, 2021 - Elsevier
Objective Platinum-resistant, high-grade serous ovarian cancer (HGSOC) has limited
treatment options. Preclinical data suggest that poly(ADP-ribose) polymerase inhibitors (PARPi) …

[HTML][HTML] A PET imaging agent for evaluating PARP-1 expression in ovarian cancer

…, DA Mankoff, F Simpkins… - The Journal of …, 2018 - Am Soc Clin Investig
BACKGROUND. Poly(ADP-ribose) polymerase (PARP) inhibitors are effective in a broad
population of patients with ovarian cancer; however, resistance caused by low enzyme …

[HTML][HTML] Nuclear envelope structural defects cause chromosomal numerical instability and aneuploidy in ovarian cancer

CD Capo-chichi, KQ Cai, F Simpkins, P Ganjei-Azar… - BMC medicine, 2011 - Springer
Background Despite our substantial understanding of molecular mechanisms and gene
mutations involved in cancer, the technical approaches for diagnosis and prognosis of cancer …

[HTML][HTML] RING domain–deficient BRCA1 promotes PARP inhibitor and platinum resistance

…, E George, EM Swisher, F Simpkins… - The Journal of …, 2016 - Am Soc Clin Investig
Patients with cancers that harbor breast cancer 1 (BRCA1) mutations initially respond well to
platinum and poly(ADP-ribose) polymerase inhibitor (PARPi) therapy; however, resistance …

Cisplatin resistance in human cervical, ovarian and lung cancer cells

…, H Parekh, F Simpkins, H Simpkins - Cancer chemotherapy …, 2015 - Springer
Purpose This study was performed to determine whether or not in cervical, ovarian and lung
cancer cell lines, free radicals (ROS) play a role in cisplatin cytotoxicity and activation of the …

[PDF][PDF] CCNE1 copy number is a biomarker for response to combination WEE1-ATR inhibition in ovarian and endometrial cancer models

…, AR Karpf, R Drapkin, EJ Brown, F Simpkins - Cell Reports …, 2021 - cell.com
CCNE1-amplified ovarian cancers (OVCAs) and endometrial cancers (EMCAs) are associated
with platinum resistance and poor survival, representing a clinically unmet need. We …
