Joint Fragmentomic and Methylation Signatures of cfDNA for Cancer Detection by Billy Lau at London Calling 2024

Billy Lau from Stanford University returned to London Calling 2024 and spoke about “Joint fragmentomic and methylation signatures of cfDNA for cancer detection.” They began by defining liquid biopsies for non-invasive cancer measurement as typically being blood draws used for sequencing and multi-omic analyses. They also explained how epigenetic reprogramming in cancer occurs and how […]

Fusion and Methylation Detection for Pediatric Tumors

Mathilde Filser from the Curie Institute in France spoke about “Simultaneous methylation and fusion detection for pediatric tumor characterization” at London Calling 2024. They explained that neuro-oncology includes many entities and DNA methylation has an “undeniable impact.” The gold standard is the Illumina EPIC array. The lab developed a workflow for frozen brain tumor samples. […]

Real-time Genomic Characterization of Pediatric Acute Leukemia with Adaptive Sampling

Julie Geyer from The University of North Carolina at Chapel Hill presented at London Calling 2024 on “Real-time genomic characterization of pediatric acute leukemia using adaptive sampling. They explained that leukemia can be acute myeloid leukemia or acute lymphoblastic leukemia. The presence of immature cells is typically performed with karyotype analysis, fluorescence in-situ hybridization (FISH), […]

Assembling a T2T Gyr Cattle Genome with Oxford Nanopore Reads

Temitayo A. Olagunju from the University of Idaho presented at London Calling 2024 on “Assembling a T2T cattle genome with Oxford Nanopore reads.”The breed of cattle they focused on is the gyr, with a characteristic hum on the back and important for milk production. They are often intercrossed/interbred with other bos cattle for their features […]

Epitranscriptomics: Identifying m6A RNA Modifications in Neuroblastoma Cell Lines

Tonight, I watched Jade Foster from the University of Southampton in the UK present at London Calling 2024. The session’s title was “Identifying m6A RNA modifications in neuroblastoma cell lines.” They explained that epitranscriptomics describes the modification of RNA molecules. There are over 150 RNA modifications determined by readers, writers, and erasers! This process is […]
