Selective amputation of the pharynx identifies a FoxA-dependent regeneration program in planaria
eLife, 2014 Planarian flatworms regenerate every organ after amputation. Adult pluripotent stem cells drive this ability, but how injury activates and directs stem cells into the appropriate lineages is unclear.

Hedgehog signaling regulates gene expression in planarian glia
eLife, 2016 Hedgehog signaling is critical for vertebrate central nervous system (CNS) development, but its role in CNS biology in other organisms is poorly characterized. In the planarian Schmidtea mediterranea, hedgehog (hh) is expressed in medial cephalic ganglia

A Systematic Review on Non-mammalian Models in Epilepsy Research
Frontiers in Pharmacology, 2018 Epilepsy is a common neurological disorder characterized by seizures which result in distinctive neurobiological and behavioral impairments. Not much is known about the causes of epilepsy, making it difficult to devise an effective cure for epilepsy ...

Biological Reviews, EarlyView.ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...

eLife, 2016 In contrast to transcriptional regulation, the function of alternative splicing (AS) in stem cells is poorly understood. In mammals, MBNL proteins negatively regulate an exon program specific of embryonic stem cells; however, little is known about the in

The spread of non‐native species
Biological Reviews, EarlyView.ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Environmental Toxicology, EarlyView.ABSTRACT Butylparaben (BuP) recurrently contaminates soils worldwide, mainly by incorporating sewage sludge into cultivated areas, using wastewater in irrigation, and leaching contaminated soils. However, there are few studies on the ecotoxicological effects of this paraben on edaphic organisms.
