First record of hagfish (Cyclostomata: Myxinidae) in Indian waters

Journal of Threatened Taxa, 2017
One specimen of hag fish Eptatretus sp. was collected from the Arabian Sea, off Kerala coast of India at 500-600 m depth. The phylogenetic analysis using the sequence of mitochondrial gene cytochrome oxidase C (CO1) suggested the Eptatretus sp. collected

A novel feature of the ancient organ: A possible involvement of the subcommissural organ in neurogenic/gliogenic potential in the adult brain

Frontiers in Neuroscience, 2023
The subcommissural organ (SCO) is a circumventricular organ highly conserved in vertebrates from Cyclostomata such as lamprey to mammals including human.

Phylogenetically Widespread Polyembryony in Cyclostome Bryozoans and the Protracted Asynchronous Release of Clonal Brood-Mates. [PDF]

PLoS ONE, 2017
Polyembryony-the production of multiple cloned embryos from a single fertilised egg-is a seemingly paradoxical combination of reproductive modes that nevertheless persists in diverse taxa. We document features of polyembryony in the Cyclostomata (Bryozoa)

The First Analysis of Synaptonemal Complexes in Jawless Vertebrates: Chromosome Synapsis and Transcription Reactivation at Meiotic Prophase I in the Lamprey Lampetra fluviatilis (Petromyzontiformes, Cyclostomata)

Life, 2023
Transcription is known to be substage-specific in meiotic prophase I. If transcription is reactivated in the mid pachytene stage in mammals when synapsis is completed, then this process is observed in the zygotene stage in insects.

iso-Petromyroxols: Novel Dihydroxylated Tetrahydrofuran Enantiomers from Sea Lamprey (Petromyzon marinus)

Molecules, 2015
An enantiomeric pair of new fatty acid-derived hydroxylated tetrahydrofurans, here named iso-petromyroxols, were isolated from sea lamprey larvae-conditioned water.

Genomic and transcriptomic survey of bryozoan Hox and ParaHox genes with emphasis on phylactolaemate bryozoans

BMC Genomics, 2023
Background Bryozoans are mostly sessile aquatic colonial invertebrates belonging to the clade Lophotrochozoa, which unites many protostome bilaterian phyla such as molluscs, annelids and brachiopods.

Petromylidenes A–C: 2-Alkylidene Bile Salt Derivatives Isolated from Sea Lamprey (Petromyzon marinus)

Marine Drugs, 2018
Three novel bile acid derivatives, petromylidenes A–C (1–3), featuring uncommon alkylidene adductive scaffolds, were isolated from water conditioned with sexually mature male sea lampreys (Petromyzon marinus). Their structures were elucidated

Benthic bryozoan fauna from the Northern Egyptian coast

Egyptian Journal of Aquatic Research, 2014
The present paper presents taxonomical information on a small bryozoan fauna collected from the Eastern Mediterranean coast of Egypt. Eight species of benthic bryozoans are reported from the trash crop of a trawling net in the area between Damietta and ...

Evolution of hes gene family in vertebrates: the hes5 cluster genes have specifically increased in frogs

BMC Ecology and Evolution, 2021
Background hes genes are chordate homologs of Drosophila genes, hairy and enhancer of split, which encode a basic helix-loop-helix (bHLH) transcriptional repressor with a WRPW motif.
