Spatiotemporal expression of a twist homolog in the leech Helobdella austinensis [PDF]
Development Genes and Evolution, 2017 Genes of the twist family encode bHLH transcription factors known to be involved in the regulation and differentiation of early mesoderm. Here, we report our characterization of Hau-twist, a twist homolog from the leech Helobdella austinensis, a tractable lophotrochozoan representative.

The effects of loose, firm, fine, and coarse substrates on the movement of the red flour beetle
Insect Science, Volume 32, Issue 2, Page 662-674, April 2025.The study focused on the impact of substrate roughness on movement properties, utilizing the red flour beetle as a model organism. Findings revealed significant variations in movement behavior between rough and smooth substrates, with beetles traveling longer distances on smooth surfaces compared to sandpaper and loose sand.

Appearance and localization of acetylcholinesterase in embryos of the leech Helobdella triserialis [PDF]
The Journal of Neuroscience, 1981 The appearance and localization of acetylcholinesterase (AchE) were studied during embryonic development of the leech Helobdella triserialis. Use of a histochemical stain showed that AchE is present in the polar plasms of the uncleaved leech egg. in the course of the first two cleavages, the AchE is transmitted along with the polar plasms mainly to the
