Invasive and non-invasive congeneric Centaurea (Asteraceae) show contrasting patterns of herbivory by snails [PDF]

open access: yes, 2016
Background and aims – Once introduced into new regions, exotic species often experience shifts in resource allocation in response to the different environmental conditions found in the introduction range. Plants naturally respond to specialist herbivores

GATA Transcription Factors: A Cross‐Road for Erythropoiesis, Neurodevelopment, and Synucleinopathies

open access: yesDevelopmental Neurobiology, Volume 85, Issue 3, July 2025.
ABSTRACT Alpha‐synuclein (α‐syn), a 140 amino acid protein, is abundantly expressed in the central nervous system (CNS) and in the erythrocytes, playing a pivotal role in the pathogenesis of Parkinson's disease (PD) and other synucleinopathies.

Integrated Analysis of Survival, Physiological‐Biochemical, and Transcriptomic Changes Reveals the Impact of Saline Stress on the Freshwater Snail Pomacea canaliculata

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
In this study, we investigated the effects of a range of salinity on the apple snail Pomacea canaliculata, a highly invasive species and an important pest of rice. To examine the molecular response of P. canaliculata to salinity, we recorded young snails grown in a saline water environment for 4 months and compared their physiological and biochemical ...

An unexpected twist: Sperm cells coil to the right in land snails and to the left in song birds [PDF]

open access: yes, 2017
In animals, cell polarity may initiate symmetry breaking very early in development, ultimately leading to whole-body asymmetry. Helical sperm cells, which occur in a variety of animal clades, are one class of cells that show clearly visible bilateral

Transforming Growth Factor‐β Pathway: Biological Functions and Therapeutic Targets

open access: yesMedComm, Volume 6, Issue 7, July 2025.
Natural compounds modulate the TGF‐β pathway, which acts as both a tumor suppressor and promoter during cancer progression. Agents such as ginsenosides, halofuginone, and EGCG influence cell proliferation, apoptosis, and angiogenesis. These bioactive molecules may complement standard therapies, highlighting the need for advanced formulations ...

Critical time window for NO-cGMP-dependent long-term memory formation after one-trial appetitive conditioning [PDF]

open access: yes, 2002
The nitric oxide (NO)-cGMP signaling pathway is implicated in an increasing number of experimental models of plasticity. Here, in a behavioral analysis using one-trial appetitive associative conditioning, we show that there is an obligatory requirement ...
