A Map of the Human X Chromosome

Karen Miga from the University of California, Santa Cruz, presented at London Calling 2019 on “Telomere-to-telomere assembly of a complete human X chromosome.” Miga is part of the Telomere-to-Telomere Consortium. They spoke about the gaps in the human genome. The challenge of assembling repeat regions may be tackled with ultra-long reads. Using the Josh Quick […]

Improving Detection of Cancer Mutations with CyclomicsSeq

Tonight I watched Jeroen de Ridder from the University Medical Center Ultrecht in the Netherlands present at London Calling 2019. They spoke about “Cyclomics: ultra-sensitive nanopore sequencing of cell-free tumor DNA.” Ridder spoke about the importance of detecting the recurrence of cancer in patients. Common diagnostics may not be suitable, and liquid biopsies of the […]

RAGE-seq and CITE-seq

Martin Smith from the Garvan Institute of Medical Research in Australia was mentioned in the London Calling 2019 session I watched yesterday. Today, I watched the recording of the 2019 London Calling session that Smith did on “Leveraging long reads for high-throughput multiomic analyses of cellular diversity in human tumours.” Smith wasn’t able to travel, […]

GRAID to Facilitate Technology Transfer and Training

Tonight, I watched the recording of Lucky Ronald Runtuwene from the University of Tokyo in Japan from London Calling 2019. Runtuwene is part of a sequencing core at a university campus. They have several Illumina devices and a PromethION. Their goal is to expedite research in developing countries. They started a collaboration with Indonesia, starting […]

Detection of RNA Modifications

Eva Maria Novoa from the Center for Genomic Regulation in Spain presented at London Calling 2019 a session on “Accurate detection of m6A RNA modification in native RNA sequences using third-generation sequencing.” Novoa emphasized there is a difference between RNA levels and protein. They have been working in this field. Interestingly, RNA modifications have been […]

Nonsense-mediated Decay of mRNAs

Evangelos Karousis from the University of Bern in Switzerland presented at London Calling 2019 on “Splice isoform-specific analysis of endogenous NMD targets in human cells.” Karousis explained that RNA degradation is involved in various biological functions, and nonsense-mediated decay (NMD) is not well understood. Nonsense mRNA is dangerous because it can contribute to disease. NMD […]

The Challenges of Sequencing tRNAs

Tonight, I watched the London Calling 2019 session by Irina Chelysheva from the University of Hamburg in Germany. The session’s title is “Small, modified, and highly structured: the challenge of tRNA sequencing.” Their lab is interested in sequencing tRNA because it is challenging. The major problems for sequencing, Chelysheva noted, include the short length of […]

Epstein-Barr Virus and Methylation Patterns

Christopher Oakes from The Ohio State University spoke at London Calling 2019 on “Discerning the origin of Epstein-Barr virus in patients using nanopore-derived DNA methylation signatures.” Oakes spoke about how they study tumor viruses and cancer. The Epstein-Barr virus is common, the “prototypical cancer virus,” according to Oakes. Immune cells suppress the virus, but the […]
