The Evolution from HG19 to HG38
Welcome to another blog post! Reference genomes are essential benchmarks of a species’ genome that facilitate the accurate comparison of individual genomes and are crucial tools for identifying genetic variants and diagnosing rare diseases. Here, we will explore the evolution of the human reference genome, focusing on the transition…
A Benchmark of Genetic Variant Calling Pipelines Using Metagenomic Short-Read Sequencing
Introduction Short-read metagenomic sequencing is the technique most widely used to explore the natural habitat of millions of bacteria. In comparison with 16S rRNA sequencing, shotgun metagenomic sequencing (MGS) provides sequence information of the whole genomes, which can be used to identify different genes present in an individual bacterium and…

Archaic Introgression Shaped Human Circadian Traits | Genome Biology and Evolution
Abstract When the ancestors of modern Eurasians migrated out of Africa and interbred with Eurasian archaic hominins, namely, Neanderthals and Denisovans, DNA of archaic ancestry integrated into the genomes of anatomically modern humans. This process potentially accelerated adaptation to Eurasian environmental factors, including reduced ultraviolet radiation and increased variation in…

KCNQ potassium channels modulate Wnt activity in gastro-oesophageal adenocarcinomas
Introduction The KCNQ (potassium voltage-gated channel subfamily Q) family of ion channels encode potassium transporters (1). KCNQ proteins typically repolarise the plasma membrane of a cell after depolarisation by allowing the export of potassium ions, and are therefore involved in wide-ranging biological functions including cardiac action potentials (2), neural excitability…
