Mechanism of efficacy of trabectedin against myxoid liposarcoma entails detachment of the FUS-DDIT3 transcription factor from its DNA binding sites.

Background: The marine drug trabectedin has shown unusual effectiveness in the treatment of myxoid liposarcoma (MLPS), a liposarcoma characterized by the expression of the FUS-DDIT3 chimera. Trabectedin elicits a significant transcriptional response in MLPS resulting in cellular depletion and reactivation of adipogenesis. However, the role of the chimeric protein in the mechanism of action of the drug is not entirely understood.

Molecular tumor board in patients with metastatic breast cancer.

Purpose: Comprehensive genomic profiling is becoming increasingly important in the management of patients with metastatic breast cancer (mBC). Real-world clinical outcomes from applying molecular tumor boards (MTBs) recommendations in this context remain limited. Accordingly, we conducted a retrospective, single-institution analysis to evaluate the clinical impact of discussing patients affected by mBC at the MTB.

Dopamine neuron dysfunction and loss in the PrknR275W mouse model of juvenile parkinsonism.

Mutations in the PRKN gene encoding the protein parkin cause autosomal recessive juvenile parkinsonism (ARJP). Harnessing this mutation to create an early-onset Parkinson's disease mouse model would provide a unique opportunity to clarify the mechanisms involved in the neurodegenerative process and lay the groundwork for the development of neuroprotective strategies. To this end, we created a knock-in mouse carrying the homozygous PrknR275W mutation, which is the missense mutation with the highest allelic frequency in PRKN patients.

Survival Outcomes by Race Following Surgical Treatment for Upper Tract Urothelial Carcinoma.

Objective: Discrepancies in survival outcomes of various genitourinary tract malignancies have been documented across different racial and ethnic groups. Here we sought to examine long-term survival outcomes of patients with upper tract urothelial carcinoma (UTUC) following radical nephroureterectomy (RNU) when stratified by race.

Methods: A multicenter retrospective analysis using the ROBUUST (ROBotic surgery for Upper tract Urothelial cancer Study) registry identified patients undergoing RNU for UTUC between 2015 and 2022 at 12 centers across the United States, Europe, and Asia.

Primary pyeloplasty for uretero-pelvic obstruction in the USA adult population with or without double-J indwelling ureteral stents. Insurance claims data on contemporary time to removal trends, perioperative complications, health care costs, and re-intervention rates.

Background: Using a large population-based dataset, we primarily sought to compare postoperative complications, health-care expenditures, and re-intervention rates between patients diagnosed with ureteropelvic junction obstruction (UPJO) undergoing stented vs. non-stented pyeloplasty. The secondary objective was to investigate factors that influence the timing of DJ stent removal.

Robot-assisted nephroureterectomy: surgical and mid-term oncological outcomes in over 1100 patients (ROBUUST 2.0 collaborative group).

Objective: To analyse surgical, functional, and mid-term oncological outcomes of robot-assisted nephroureterectomy (RANU) in a contemporary large multi-institutional setting.

Patients And Methods: Data were retrieved from the ROBotic surgery for Upper tract Urothelial cancer STtudy (ROBUUST) 2.0 database, an international, multicentre registry encompassing data of patients with upper urinary tract urothelial carcinoma undergoing curative surgery between 2015 and 2022.

A high-throughput screening identifies MCM chromatin loading inhibitors targeting cells with increased replication origins.

Replication origin assembly is a pivotal step in chromosomal DNA replication. In this process, the ORC complex binds DNA and, together with the CDC6 and CDT1, promotes the loading of the MCM helicase. Chemicals targeting origin assembly might be useful to sensitize highly proliferative cancer cells.

The impact of bladder cuff excision on outcomes after nephroureterectomy for upper tract urothelial carcinoma: An analysis of the ROBUUST 2.0 registry.

Objectives: We sought to determine whether bladder cuff excision and its technique influence outcomes after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC).

Methods And Materials: A multicenter, international, retrospective analysis using the ROBotic surgery for Upper tract Urothelial cancer Study (ROBUUST) 2.0 registry identified 1,718 patients undergoing RNU for UTUC between 2015 and 2023 at 17 centers across the United States, Europe, and Asia.

Increased levels of circulating cell-free double-stranded nucleic acids in the plasma of glioblastoma patients.

Circulating cell-free nucleic acids are considered a promising source of biomarkers for diseases and cancer. Liquid biopsy biomarkers for brain tumours represent a major, still unmet, clinical need. In plasma, nucleic acids can be free or be associated with extracellular vesicles (EVs).

Lower PHI, [-2]proPSA/fPSA and testosterone/estradiol ratios in healthy black men: preliminary results and potential implications in prostate cancer clinical management.

Background: Black men residing in Western countries are more likely to develop prostate cancer (PCa), have higher mortality and are younger than the general population at initial diagnosis. In addition to genetic and environmental factors, the reasons for these racial disparities can also be attributed to social determinants of health such as low health literacy of this population and poor awareness of health services. Little is known about laboratory tests for PCa in black men.

GPR126 is a specifier of blood-brain barrier formation in the mouse central nervous system.

The blood-brain barrier (BBB) acquires unique properties to regulate neuronal function during development. The formation of the BBB, which occurs in tandem with angiogenesis, is directed by the Wnt/β-catenin signaling pathway. Yet the exact molecular interplay remains elusive.

Immunotherapy in Neuroendocrine Neoplasms: A Diamond to Cut.

A raise in the incidence of NENs is expected. Therefore, the identification of new therapeutic strategies, such as immunotherapy, remains crucial. To date, immune checkpoint inhibitors as monotherapy have shown modest activity in unselected NENs.

Multiscale modeling uncovers 7q11.23 copy number variation-dependent changes in ribosomal biogenesis and neuronal maturation and excitability.

Copy number variation (CNV) at 7q11.23 causes Williams-Beuren syndrome (WBS) and 7q microduplication syndrome (7Dup), neurodevelopmental disorders (NDDs) featuring intellectual disability accompanied by symmetrically opposite neurocognitive features. Although significant progress has been made in understanding the molecular mechanisms underlying 7q11.

Lower limb lymphedema after surgical staging for endometrial cancer: Current insights and future directions.

Lower extremity lymphedema (LEL) is a common complication following surgical staging of endometrial cancer. LEL is a chronic condition associated with significant impact on patient morbidity and quality of life (QoL). This review aimed to report the current evidence in the literature on secondary LEL after surgical staging for endometrial cancer, focusing on the incidence based on different approaches to lymph node staging, diagnosis, risk factors, and the impact on QoL.

A randomized phase II trial of Captem or Folfiri as second-line therapy in neuroendocrine carcinomas.

Background: Neuroendocrine Carcinomas (NECs) prognosis is poor.No standard second-line therapy is currently recognized after failure of platinum-based first-line treatment. FOLFIRI and CAPTEM regimens have shown promising activity in preliminary studies.

miRNA-mediated inhibition of an actomyosin network in hippocampal pyramidal neurons restricts sociability in adult male mice.

Social deficits are frequently observed in patients suffering from neurodevelopmental disorders, but the molecular mechanisms regulating sociability are still poorly understood. We recently reported that the loss of the microRNA (miRNA) cluster miR-379-410 leads to hypersocial behavior and anxiety in mice. Here, we show that ablating miR-379-410 in excitatory neurons of the postnatal mouse hippocampus recapitulates hypersociability, but not anxiety.

The detection rate for prostate cancer in systematic and targeted prostate biopsy in biopsy-naive patients, according to the localization of the lesion at the mpMRI: A single-center retrospective observational study.
