Assessment of PIT tag retention and post-tagging survival in metamorphosing juvenile sea lamprey

open access: yesAnimal Biotelemetry, 2017
Background Passive integrated transponder (PIT) tags have been used to document and monitor the movement, behavior, or survival of numerous species of fishes.

Ancient Pbx-Hox signatures define hundreds of vertebrate developmental enhancers [PDF]

open access: yes, 2011
Background: Gene regulation through cis-regulatory elements plays a crucial role in development and disease. A major aim of the post-genomic era is to be able to read the function of cis-regulatory elements through scrutiny of their DNA sequence ...

Ethnozoological knowledge of traditional fishing villages about the anadromous sea lamprey (Petromyzon marinus) in the Minho river, Portugal

open access: yesJournal of Ethnobiology and Ethnomedicine, 2019
Background Sea lamprey (Petromyzon marinus) is a diadromous fish compromised by various stressors, which can lead to population decline and the urgency of stronger conservation regulation.

3D model of lamprey estrogen receptor with estradiol and 15alpha-hydroxy-estradiol. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:Lamprey, basal vertebrate, is an important model system for understanding early events in vertebrate evolution. Lamprey contains orthologs of the estrogen receptor [ER], progesterone receptor and corticoid receptor.

Life cycle of the sea lamprey Petromyzon marinus: duration of and growth in the marine life stage

open access: yesAquatic Biology, 2013
Little is known about the marine life-history phase of the anadromous sea lamprey Petromyzon marinus. The most widely accepted hypothesis suggests a hematophagous feeding phase of 2.5 yr.

Shedding light on the river and sea lamprey in western European marine waters

open access: yesEndangered Species Research, 2021
Lampreys are ancestral jawless vertebrates with particularly complex life histories. Population declines resulting from increased anthropogenic pressure have been observed. For semelparous diadromous lampreys, the marine phase remains largely a black box,

Enantioselective synthesis of (+)-petromyroxol, enabled by rhodium-catalyzed denitrogenation and rearrangement of a 1-sulfonyl-1,2,3-triazole [PDF]

open access: yes, 2015
Petromyroxol is a non-racemic mixture of enantiomeric oxylipids isolated from water conditioned with larval sea lamprey. The (+)-antipode exhibits interesting biological properties but only 1 mg was isolated from >100000 L of water.

Hsp90 and hepatobiliary transformation during sea lamprey metamorphosis [PDF]

open access: yesBMC Developmental Biology, 2015
Abstract Background Biliary atresia (BA) is a human infant disease with inflammatory fibrous obstructions in the bile ducts and is the most common cause for pediatric liver transplantation. In contrast, the sea lamprey undergoes developmental BA with transient cholestasis and fibrosis during metamorphosis, but emerges as

Registration and application of sea lamprey pheromones for sea lamprey control in the United States and Canada

open access: yesJournal of Great Lakes Research, 2021
Abstract Since the identification of 3-trifluoromethyl-4-nitrophenol as a lampricide in the 1950s, control of sea lamprey populations in the Great Lakes has largely relied on lampricides, barriers, and traps. Lampricide treatments target larval lampreys in tributaries of the Great Lakes. The Great Lakes Fishery Commission oversees sea lamprey control

Generation of Lamprey Monoclonal Antibodies (Lampribodies) Using the Phage Display System. [PDF]

open access: yes, 2019
The variable lymphocyte receptors (VLRs) consist of leucine rich repeats (LRRs) and comprise the humoral antibodies produced by lampreys and hagfishes.
