Detecting the Epigenome with ONT

Chen Yong from Oxford Nanopore helped facilitate the Knowledge Exchange session I watched tonight: “Decoding the epigenome with Oxford Nanopore real-time methylation detection.” This webinar was recorded. Sayonika Mohanta from ONT explained that methylation is central to gene expression. They spoke about the role of methylation in gene expression: her or hypo methylation can affect […]

Rapid Chromosome Evolution in Gibbons

Gabrielle Hartley from the University of Connecticut presented at London Calling 2023 a lightning talk. The session’s title is “Telomere-to-telomere nanopore-based genome assembly reveals genomic and epigenetic features of karyotype radiation.” Hartley is a graduate student and is studying the evolution of gibbons. They noted that, unlike other apes, gibbons “have highly rearranged karyotypes concomitant […]

Highly Multiplex Aptamer-based Biomarker Detection with ONT

Caroline Koch from the Imperial College in London, UK, presented at London Calling 2023 a lightning talk on “Novel screening platform for highly multiplexed biomarker analysis.” Koch was a Ph.D. student and explained why we need methods for multiplexed biomarker detection by emphasizing how we all express diseases differently and need sensitive diagnostic methods. They […]

Identification of Extrachromosomal Circular DNA Molecules in Cancer Patients

Fei Xiao from the Beijing Hospital in China presented at London Calling 2023 a lightning talk on “Small extrachromosomal circular DNAs as biomarkers for potential pan-cancer diagnosis and prognosis.” Xiao noted that extrachromosomal circular DNA (eccDNA) are circular DNA molecules that are independent of conventional chromosomes and most are smaller than 10 kb. The study […]

Structural Variants from the Bovine Long Read Consortium

I am continuing to watch the London Calling 2023 on-demand lightning talks. Tonight, I watched the session “Discovering the missing variation: a long-read sequencing study into the structural variation in two dairy breeds” by Tuan Viet Nguyen, a research scientist from Agriculture Victoria in Australia. They spoke about structural variants, defined as genomic variants larger […]
