Mapping molluscan endocrinology: a systematic and critical appraisal
Biological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Ergosterol biosynthesis inhibition: a target for antifungal agents.
Acta Biochimica Polonica, 1995 The isoprenoid sterols play a crucial role in the viability of all fungi; those unable to synthesise ergosterol because of inhibition, growth conditions or mutation must take it up from the environment. A range of compound types have been discovered which interfere with the biosynthetic pathway from acetate to ergosterol and these compounds have ...
