A hypoxia-related signature in lung squamous cell carcinoma
Introduction Lung cancer is the major leading cause of tumour-related deaths throughout the world, while lung squamous cell carcinoma (LUSC) as the second most common histological type of lung cancer.1 Each year, almost 1.8 million people are diagnosed with lung cancer worldwide and 400,000 of these die from LUSC.2,3 Due to…
RNA polymerase II trapped on a molecular treadmill: Structural basis of persistent transcriptional arrest by a minor groove DNA binder
Significance Hairpin pyrrole-imidazole (Py-Im) polyamides can be programmed to bind a broad repertoire of DNA sequences. Py-Im small molecules can be used to target cancer-specific coding regions and block transcription elongation. This transcription blockage by Py-Im cannot be rescued by transcription elongation factors, such as TFIIS. The mechanism by which…

Characterization of Blood- Based Molecular Profiling in Pancreatic Adenocarcinoma
Introduction Most cases of pancreatic adenocarcinoma (PDAC) are diagnosed in the metastatic or locally advanced stage. It is the fourth leading cause of cancer death in the United States,1,2 with a 5-year overall survival (OS) around 10% in this country2 despite years of research and therapeutic development. For those patients…

Data Demonstrates Lucence Liquid Biopsy Test Can Track Treatment-Based ctDNA Changes
NEW YORK – At the European Society for Medical Oncology Congress this week, precision oncology assay developer Lucence presented data that demonstrated its amplicon-based LiquidHallmark assay could be used to personalize care for people with advanced urothelial carcinoma. LiquidHallmark is a laboratory-developed test based on the company’s AmpliMark next-generation sequencing platform…
The Current Molecular Treatment Landscape of Advanced Colorectal Cancer and Need for the COLOMATE Platform
Next-Generation Sequencing Utilizing Tumor Tissue and/or Blood The identification of actionable genomic alterations in tumors such as mCRC was once performed by Sanger DNA sequencing of tumor DNA that was extracted from fixed paraffin-embedded tumor tissue, but this has now been replaced by next-generation sequencing (NGS), which allows for larger-scale…
Dual Targeting of CDKN2A and PIK3CA May Offer Better Outcomes in Urothelial Carcinoma
Genomic testing varies in the academic and community setting. For community settings, commercial panels are available. However, academic settings have access to tools that provide a more comprehensive views of the genome. Investigators used patient-derived UC organoid (PDO) harboring FGFR3, PIK3CA, and CDKN2A mutations. Dose-response curves of alpelisib (Piqray), abemaciclib…
Oncogene Concatenated Enriched Amplicon Nanopore Sequencing for rapid, accurate, and affordable somatic mutation detection | Genome Biology
Stochastic Amplicon Ligation. DNA samples for oncology sequencing are typically extracted from FFPE tissues and can have average lengths of less than 500 nt due to accumulated chemical damage [18]. We developed the Stochastic Amplicon Ligation (SAL) method to enzymatically concatenate many short DNA molecules together to utilize the long-read…
