N-Terminally extended analogues of the K⁺ channel toxin from Stichodactyla helianthus as potent and selective blockers of the voltage-gated potassium channel Kv1.3. [PDF]

open access: yesFEBS J, 2015
The voltage-gated potassium channel Kv1.3 is an important target for the treatment of autoimmune diseases and asthma. Blockade of Kv1.3 by the sea anemone peptide K+-channel toxin from Stichodactyla helianthus (ShK) inhibits the proliferation of effector

Sticholysins, two pore-forming toxins produced by the Caribbean Sea anemone Stichodactyla helianthus: their interaction with membranes.

open access: yesToxicon, 2009
Sticholysins (Sts) I and II (StI/II) are pore-forming toxins (PFTs) produced by the Caribbean Sea anemone Stichodactyla helianthus belonging to the actinoporin family, a unique class of eukaryotic PFTs exclusively found in sea anemones. As for the rest of the members of this family, Sts are cysteine-less proteins, with molecular weights around 20 kDa ...

Sticholysin I–II oligomerization in the absence of membranes

open access: yesFEBS Letters, Volume 596, Issue 8, Page 1029-1036, April 2022., 2022
In this study, the oligomerization in solution of StnI and StnII, two pore‐forming toxins produced by Stichodactyla helianthus, has been studied using analytical ultracentrifugation. Our results show that while StnI is more prone to oligomerize than StnII when assayed independently, the addition of a small amount of StnII favours oligomerization ...

Discovery of KV1.3 ion channel inhibitors: Medicinal chemistry approaches and challenges

open access: yesMedicinal Research Reviews, Volume 41, Issue 4, Page 2423-2473, July 2021., 2021
Abstract The KV1.3 voltage‐gated potassium ion channel is involved in many physiological processes both at the plasma membrane and in the mitochondria, chiefly in the immune and nervous systems. Therapeutic targeting KV1.3 with specific peptides and small molecule inhibitors shows great potential for treating cancers and autoimmune diseases, such as ...

Omics‐based molecular analyses of adhesion by aquatic invertebrates

open access: yesBiological Reviews, Volume 96, Issue 3, Page 1051-1075, June 2021., 2021
ABSTRACT Many aquatic invertebrates are associated with surfaces, using adhesives to attach to the substratum for locomotion, prey capture, reproduction, building or defence. Their intriguing and sophisticated biological glues have been the focus of study for decades.

Treatment of Radiation‐Induced Brain Necrosis

open access: yesOxidative Medicine and Cellular Longevity, Volume 2021, Issue 1, 2021., 2021
Radiation‐induced brain necrosis (RBN) is a serious complication of intracranial as well as skull base tumors after radiotherapy. In the past, due to the lack of effective treatment, radiation brain necrosis was considered to be progressive and irreversible. With better understanding in histopathology and neuroimaging, the occurrence and development of

Panorama of the Intracellular Molecular Concert Orchestrated by Actinoporins, Pore-Forming Toxins from Sea Anemones

open access: yesToxins, 2021
Actinoporins (APs) are soluble pore-forming proteins secreted by sea anemones that experience conformational changes originating in pores in the membranes that can lead to cell death. The processes involved in the binding and pore-formation of members of
