Modulation of Locomotion and Reproduction by FLP Neuropeptides in the Nematode Caenorhabditis elegans. [PDF]

open access: goldPLoS ONE, 2015
Neuropeptides function in animals to modulate most, if not all, complex behaviors. In invertebrates, neuropeptides can function as the primary neurotransmitter of a neuron, but more generally they co-localize with a small molecule neurotransmitter, as is

Insect Mating Behaviors: A Review of the Regulatory Role of Neuropeptides [PDF]

open access: yesInsects
Insect mating behaviors are complex, diverse, and primarily regulated by neuropeptides and their receptors. Neuropeptides are peptide signaling molecules mainly secreted by insects’ central nervous system (CNS) to reach target organs.

Antinociceptive and Cytotoxic Activity of Opioid Peptides with Hydrazone and Hydrazide Moieties at the C-Terminus

open access: yesMolecules, 2020
In the present contribution, we analyze the influence that C-terminal extension of short opioid peptide sequences by organic fragments has on receptor affinity, in vivo analgesic activity, and antimelanoma properties.

Can keratin scaffolds be used for creating three-dimensional cell cultures?

open access: yesOpen Medicine, 2020
Three-dimensional (3D) cell cultures were created with the use of fur keratin associated proteins (F-KAPs) as scaffolds. The procedure of preparation F-KAP involves combinations of chemical activation and enzymatic digestion.

LIT01-196, a Metabolically Stable Apelin-17 Analog, Normalizes Blood Pressure in Hypertensive DOCA-Salt Rats via a NO Synthase-dependent Mechanism

open access: yesFrontiers in Pharmacology, 2021
Apelin is a neuro-vasoactive peptide that plays a major role in the control of cardiovascular functions and water balance, but has an in-vivo half-life in the minute range, limiting its therapeutic use.

Neuropeptidomics: Mass Spectrometry-Based Identification and Quantitation of Neuropeptides [PDF]

open access: yesGenomics & Informatics, 2016
Neuropeptides produced from prohormones by selective action of endopeptidases are vital signaling molecules, playing a critical role in a variety of physiological processes, such as addiction, depression, pain, and circadian rhythms.

Radiochemical Synthesis and Evaluation of Novel Radioconjugates of Neurokinin 1 Receptor Antagonist Aprepitant Dedicated for NK1R-Positive Tumors

open access: yesMolecules, 2020
Aprepitant, a lipophilic and small molecular representative of neurokinin 1 receptor antagonists, is known for its anti-proliferative activity on numerous cancer cell lines that are sensitive to Substance P mitogen action.

Starfish smooth muscle relaxing activity of SALMFamide isotype peptide and its analog derived from starfish, Asterias rubens

open access: yesFisheries and Aquatic Sciences, 2022
An organism’s physiological processes and behaviors are regulated by neuropeptides and hormone peptides. The first neuropeptide identified from echinoderms is SALMFamide.

Best Practices for Comprehensive Annotation of Neuropeptides of Gryllus bimaculatus

open access: yesInsects, 2023
Genome annotation is critically important data that can support research. Draft genome annotations cover representative genes; however, they often do not include genes that are expressed only in limited tissues and stages, or genes with low expression ...
