A bioactive peptide amidating enzyme is required for ciliogenesis
eLife, 2017 The pathways controlling cilium biogenesis in different cell types have not been fully elucidated. We recently identified peptidylglycine α-amidating monooxygenase (PAM), an enzyme required for generating amidated bioactive signaling peptides, in ...

Picroscope: low-cost system for simultaneous longitudinal biological imaging
Communications Biology, 2021 Ly et al. report a multi-well imaging system (the Picroscope) that can perform longitudinal bright-field z-stack imaging for 24 wells simultaneously. They demonstrate its capability by imaging zebrafish embryos, planaria worms, development of Xenopus ...

Environmental Toxicology, EarlyView.ABSTRACT Bisphenol A (BPA), a common industrial chemical used in plastics and consumer products, is increasingly detected in aquatic environments, raising serious concerns about its potential ecological impacts. This study evaluated the sublethal and acute toxic effects of BPA on the freshwater planarian Girardia tigrina, a recognized model for ...

eLife, 2016 Mechanisms enabling positional identity re-establishment are likely critical for tissue regeneration. Planarians use Wnt/beta-catenin signaling to polarize the termini of their anteroposterior axis, but little is known about how regeneration signaling ...

The Journal of Physiology, EarlyView.Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Body size-dependent energy storage causes Kleiber’s law scaling of the metabolic rate in planarians
eLife, 2019 Kleiber’s law, or the 3/4 -power law scaling of the metabolic rate with body mass, is considered one of the few quantitative laws in biology, yet its physiological basis remains unknown.

Temporally-patterned magnetic fields induce complete fragmentation in planaria. [PDF]
PLoS ONE, 2013 A tandem sequence composed of weak temporally-patterned magnetic fields was discovered that produced 100% dissolution of planarian in their home environment. After five consecutive days of 6.5 hr exposure to a frequency-modulated magnetic field (0.1 to 2

Fraternal cooperation of hierarchical cancer parallels metazoan multicellularity and eusociality
Biological Reviews, Volume 101, Issue 1, Page 400-418, February 2026.ABSTRACT Metazoan multicellularity and eusociality — both outcomes of the fraternal major transitions — have numerous features in common such as uneven distribution of group‐establishing potential. In addition to this framework, I argue herein that the group‐forming principles of metazoan multicellularity and eusociality are analogous to hierarchical ...

Retinoic acid inhibition impairs planarian eye regeneration.
Impulse: The Premier Undergraduate Neuroscience Journal, 2019 Retinoic acid is a known morphogen in regulating animal growth and development. Planaria are a key model system for regeneration and their eyes are a morphological marker of anterior differentiation.
