Potential allopolyploid origin of Ericales revealed with gene-tree reconciliation
Frontiers in Plant Science, 2022 Few incidents of ancient allopolyploidization (polyploidization by hybridization or merging diverged genomes) were previously revealed, although there is significant evidence for the accumulation of whole genome duplications (WGD) in plants.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Losing Genes: The Evolutionary Remodeling of Cetacea Skin
Frontiers in Marine Science, 2020 The skin is a multi-layered organ, often displaying associated structures, that establishes a protective interface between the organism and the surrounding environment.

The ecological adaptation of the unparalleled plastome character evolution in slipper orchids
Frontiers in Plant Science, 2022 Plastomes may have undergone adaptive evolution in the process of plant adaptation to diverse environments, whereby species may differ in plastome characters.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Gene Losses during Human Origins
PLoS Biology, 2006 Pseudogenization is a widespread phenomenon in genome evolution, and it has been proposed to serve as an engine of evolutionary change, especially during human origins (the "less-is-more" hypothesis). However, there has been no comprehensive analysis of human-specific pseudogenes.

Antivirulence Genes: Insights into Pathogen Evolution through Gene Loss [PDF]
Infection and Immunity, 2012 ABSTRACT The emergence of new pathogens and the exploitation of novel pathogenic niches by bacteria typically require the horizontal transfer of virulence factors and subsequent adaptation—a “fine-tuning” process—for the successful incorporation of these factors into the microbe's genome.

Escape from preferential retention following repeated whole genome duplication in plants
Frontiers in Plant Science, 2012 The well supported gene dosage hypothesis predicts that genes encoding proteins engaged in dose-sensitive interactions cannot be reduced back to single copies once all interacting partners are simultaneously duplicated in a whole genome duplication.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
