Light-induced depigmentation in planarians models the pathophysiology of acute porphyrias

open access: yeseLife, 2016
Porphyrias are disorders of heme metabolism frequently characterized by extreme photosensitivity. This symptom results from accumulation of porphyrins, tetrapyrrole intermediates in heme biosynthesis that generate reactive oxygen species when exposed to ...

Melav2, an elav-like gene, is essential for spermatid differentiation in the flatworm Macrostomum lignano [PDF]

open access: yes, 2009
BackgroundFailure of sperm differentiation is one of the major causes of male sterility. During spermiogenesis, spermatids undergo a complex metamorphosis, including chromatin condensation and cell elongation.

Invloed van hexavalent chroom op de stamcellen van de platworm Schmidtea mediterranea. Cellulair onderzoek en vergelijking met cadmium. [PDF]

open access: yes
SAMENVATTING. Hexavalent chroom (Cr(VI)) en cadmium (Cd) zijn allebei zware metalen die zich in het milieu opstapelen, voornamelijk ten gevolge van menselijke, vooral industriële, activiteiten.

A schistosome [beta] subunit remodels inactivation of a calcium channel _via_ an N-terminal polyacidic motif [PDF]

open access: yes, 2010
The beta subunit of high voltage-activated Ca (Cav) channels targets the pore forming [alpha]~1~ subunit to the plasma membrane and defines the biophysical phenotype of the Cav channel complex. Cav channel inactivation following activation and opening is

A Dynamically Diluted Alignment Model Reveals the Impact of Cell Turnover on the Plasticity of Tissue Polarity Patterns

open access: yes, 2017
The polarisation of cells and tissues is fundamental for tissue morphogenesis during biological development and regeneration. A deeper understanding of biological polarity pattern formation can be gained from the consideration of pattern reorganisation ...

Stochastic cell-intrinsic stem cell decisions control colony growth in planarians

open access: yeseLife
Stem cells contribute to organismal homeostasis by balancing division, self-renewal, and differentiation. Elucidating the strategies by which stem cells achieve this balance is critical for understanding homeostasis and for addressing pathogenesis ...
