Gain-of-Function Chromatin Remodeling Activity of Oncogenic FOXL2-C134W Reprograms Glucocorticoid Receptor Occupancy to Drive Granulosa Cell Tumors.

Adult type ovarian granulosa cell tumors (AGCTs) are rare malignancies with the near universal c.C402G (p.Cys134Trp) somatic mutation in FOXL2, a Forkhead box-family transcription factor important for ovarian function.

promoter mutations and survival outcomes in adult-type granulosa cell tumors.

Objectives: To evaluate survival outcomes among patients with adult-type granulosa cell tumors who have telomerase reverse transcriptase () promoter mutations.

Methods: This is a retrospective cohort study using the MD Anderson Rare Gynecologic Malignancy Registry. Patients with adult granulosa cell tumors who underwent molecular testing for promoter and c.

Evaluation of a tiered opioid prescription algorithm in an ERAS pathway: exploring opportunities for further refinement.

Background: Opioid over-prescription is wasteful and contributes to the opioid crisis. We implemented a personalized tiered discharge opioid protocol and education on opioid disposal to minimize over-prescription.

Objective: To evaluate the intervention by investigating opioid use post-discharge for women undergoing abdomino-pelvic surgery, and patient adherence to opioid disposal education.

The genomic landscape of low-grade serous ovarian/peritoneal carcinoma and its impact on clinical outcomes.

Objective: Low-grade serous carcinoma (LGSOC) is a rare epithelial ovarian/peritoneal cancer characterized by younger age at diagnosis, relative chemoresistance, prolonged overall survival (OS), and mutations in the mitogen activated protein kinase (MAPK) pathway compared to high-grade serous carcinoma. We describe the genomic profile of LGSOC by next generation sequencing (NGS) and evaluated its potential relationship to clinical outcomes.

Methods: The study included 215 women with LGSOC with: 1) pathologically confirmed LGSOC, 2) availability of NGS data, and 3) adequate clinical data.

Impact of a tiered discharge opioid algorithm on prescriptions and patient-reported outcomes after open gynecologic surgery.

Objective: To compare discharge opioid refills, prescribed morphine equivalent dose and quantity, and longitudinal patient-reported outcomes before and after implementation of a tiered opioid prescribing algorithm among women undergoing open gynecologic surgery within an enhanced recovery after surgery program.

Methods: We compared opioid prescriptions, clinical outcomes, and patient-reported outcomes among 273 women. Post-discharge symptom burden was collected up to 42 days after discharge using the validated 27-item MD Anderson Symptom Inventory and analyzed using linear mixed effects models and Kaplan-Meier curves for symptom recovery.

Evaluation of PARP and PDL-1 as potential therapeutic targets for women with high-grade neuroendocrine carcinomas of the cervix.

Objectives: Women with recurrent high-grade neuroendocrine cervical cancer have few effective treatment options. The aim of this study was to identify potential therapeutic targets for women with this disease.

Methods: Specimens from patients with high-grade neuroendocrine carcinomas of the cervix were identified from pathology files at MD Anderson Cancer Center.

Kinetics and longevity of ΦC31 integrase in mouse liver and cultured cells.

The ΦC31 integrase system provides genomic integration of plasmid DNA that may be useful in gene therapy. For example, the ΦC31 system has been used in combination with hydrodynamic injection to achieve long-term expression of factor IX in mouse liver. However, a concern is that prolonged expression of ΦC31 integrase within cells could potentially stimulate chromosome rearrangements or an immune response.

Integration specificity of phage phiC31 integrase in the human genome.

The site-specific integrase from bacteriophage phiC31 functions in mammalian cells and is being applied for genetic engineering, including gene therapy. The phiC31 integrase catalyzes precise, unidirectional recombination between its 30-40-bp attP and attB recognition sites. In mammalian cells, the enzyme also mediates integration of plasmids bearing attB into native sequences that have partial sequence identity with attP, termed pseudo attP sites.

The renin-angiotensin system does not contribute to the endothelial dysfunction and increased infarct size in rats exposed to second hand smoke.

Introduction: Both second hand smoke (SHS) and the renin-angiotensin system (RAS) contribute to endothelial dysfunction and increased infarct size in a rat ischaemia-reperfusion model. However, the potential interaction between SHS and the RAS is unknown.

Methods: Eighty-four rats were randomised into four groups: group C was a normal control; L was given 40 mg/kg/day of losartan in drinking water; SC and SL were exposed to SHS (smoking chamber) and given regular water or 40 mg/kg/day of losartan in drinking water, respectively.
