Article Synopsis
  • Pediatric ependymoma (EPN) frequently recurs, with a study tracking 30 patients showing they experienced an average of 3.67 relapses over 13 years.
  • The research identified stable molecular subtypes and significant patterns in DNA methylation that change during relapses, highlighting specific genes that are differentially expressed and might play a role in the disease's progression.
  • Findings include potential biomarkers for predicting relapses found in primary tumors, along with a detailed epigenetic profile to support future studies on EPN biology and treatment approaches.

In living cells, the genetic information stored in the DNA sequence is always associated with chromosomal and extra-chromosomal epigenetic information. Chromatin is formed by the DNA and associated proteins, in particular histones. Covalent histone modifications are important bearers of epigenetic information and as such have been increasingly studied since about the year 2000.

CRISPR/Cas9 technology has evolved as the most powerful approach to generate genetic models both for fundamental and preclinical research. Despite its apparent simplicity, the outcome of a genome-editing experiment can be substantially impacted by technical parameters and biological considerations. Here, we present guidelines and tools to optimize CRISPR/Cas9 genome-targeting efficiency and specificity.

Aim: Dyslipidemia in type 2 diabetes contributes to an increased risk of cardiovascular disease. Fenofibrate, a lipid-regulating peroxisome proliferator-activated receptor-α (PPARα) agonist, has been shown to reduce vascular complications in adults with type 2 diabetes. The mechanisms for such benefit, however, are not yet well understood.

Tandem stem cell transplantation (SCT) is an option for high-risk relapsed/refractory Hodgkin Lymphoma (HL) patients. We evaluated the tolerance/efficacy of double autologous or autologous SCT (ASCT) followed by allogenic SCT (alloSCT) in 120 HL patients prospectively registered on a French nationwide database. Median age was 26 (14-56) years.

Background: Opioid substitution treatment (OST) is often continued long-term and, therefore, opioid-associated symptoms are of interest. Symptoms associated with methadone maintenance treatment (MMT) in men are well described, but there are fewer reports concerning symptoms associated with buprenorphine maintenance treatment (BMT) and very few reports among women.

Method: Recipients of BMT (n=113) and MMT (n=184), non-opioid users (n=105) and opioid users not receiving OST (n=87) completed the Patient Assessment of Constipation (PAC-SYM) and a general symptom checklist.

Background: In the open-label randomized phase III AURELIA trial, adding bevacizumab to chemotherapy for platinum-resistant ovarian cancer (PROC) significantly improved progression-free survival and response rate versus chemotherapy alone, but not overall survival (OS). We explored the effect of bevacizumab use after disease progression (PD) in patients randomized to chemotherapy alone.

Patients And Methods: In AURELIA, 361 women with PROC were randomized to chemotherapy alone or with bevacizumab.

As chromatin immunoprecipitation (ChIP) sequencing is becoming the dominant technique for studying chromatin modifications, new protocols surface to improve the method. Bioinformatics is also essential to analyze and understand the results, and precise analysis helps us to identify the effects of protocol optimizations. We applied iterative sonication - sending the fragmented DNA after ChIP through additional round(s) of shearing - to a number of samples, testing the effects on different histone marks, aiming to uncover potential benefits of inactive histone marks specifically.

Background: To determine the minimum survival benefits that patients, and their clinicians, judged sufficient to make adjuvant chemotherapy (ACT) worthwhile, in addition to pelvic radiotherapy, for women with high risk and advanced stage endometrial cancer.

Methods: Eighty-three participants in the PORTEC-3 trial completed a time trade-off questionnaire before and after adjuvant therapy; 44 of their clinicians completed it once only. The questionnaire used four hypothetical scenarios including baseline survival times without ACT of 5 and 8 years, and baseline survival rates at 5 years without ACT of 50 and 65%.
