Genetic evidence that Nkx2.2 acts primarily downstream of Neurog3 in pancreatic endocrine lineage development

open access: yeseLife, 2017
Many pancreatic transcription factors that are essential for islet cell differentiation have been well characterized; however, because they are often expressed in several different cell populations, their functional hierarchy remains unclear.

Genetic lineage tracing defines myofibroblast origin and function in the injured heart

open access: yesNature Communications, 2016
Cardiac fibroblasts convert to myofibroblasts with injury to mediate healing after acute myocardial infarction (MI) and to mediate long-standing fibrosis with chronic disease. Myofibroblasts remain a poorly defined cell type in terms of their origins and

Analysis of World-Scale Mitochondrial DNA Reveals the Origin and Migration Route of East Asia Goats

open access: yesFrontiers in Genetics, 2022
Despite much attention on the history of goat evolution, information on origin, demographic history, and expansion route remains controversial. To address these questions, we collected 4,189 published goat DNA sequences including 1,228 sequences from 57 ...

Evolution in range expansions with competition at rough boundaries. [PDF]

open access: yes, 2018
When a biological population expands into new territory, genetic drift develops an enormous influence on evolution at the propagating front. In such range expansion processes, fluctuations in allele frequencies occur through stochastic spatial wandering ...

Genetic Variants of SARS-CoV-2-What Do They Mean?

open access: yesJournal of the American Medical Association (JAMA), 2021
Over the course of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, the clinical, scientific, and public health communities have had to respond to new viral genetic variants. Each one has triggered a flurry of media attention, a

Dissemination of Enterococcal Genetic Lineages: A One Health Perspective

open access: yesAntibiotics, 2023
Enterococcus spp. are commensals of the gastrointestinal tracts of humans and animals and colonize a variety of niches such as water, soil, and food. Over the last three decades, enterococci have evolved as opportunistic pathogens, being considered ESKAPE pathogens responsible for hospital-associated infections.

Genetic diversity and population structure of Toona ciliata revealed by simple sequence repeat markers

open access: yesBiotechnology & Biotechnological Equipment, 2019
Toona ciliata (Meliaceae) is a rare, fast-growing commercial tree species that produces red timber with beautiful grains. It used to be widely distributed in the past, but few natural forests exist in the field now.

Genetic lineages and their traits in Neisseria meningitidis

open access: yesInternational Journal of Medical Microbiology, 2004
Neisseria meningitidis is a model organism for the study of bacterial population biology, for genome sequencing and pathogenicity research. In the recent years, our group has identified a variety of markers for hypervirulent lineages of meningococci, which in part could be validated for typing purposes.
