Development of a novel denture care agent with highly active enzyme, arazyme.

Background: The importance of efficient denture deposit removal and oral hygiene has been further underscored by the continuous increase of denture wearers. Denture hygiene management has also become an important aspect associated with denture-induced stomatitis. This study aims to evaluate the denture cleaning effect of arazyme, the metalloprotease produced from the Serratia proteamaculans HY-3.

Nemopilema nomurai jellyfish venom exerts an anti-metastatic effect by inhibiting Smad- and NF-κB-mediated epithelial-mesenchymal transition in HepG2 cells.

Epithelial-mesenchymal transition (EMT) is a key initial step in metastasis for malignant cancer cells to obtain invasive and motile properties. Inhibiting EMT has become a new strategy for cancer therapy. In our previous in vivo study, Nemopilema nomurai jellyfish venom (NnV) -treated HepG2 xenograft mice group showed that E-cadherin expression was strongly detected compared with non-treated groups.

In vitro characterization of jellyfish venom fibrin(ogen)olytic enzymes from .

Background: Because jellyfish are capable of provoking envenomation in humans, they are considered hazardous organisms. Although the effects of their toxins are a matter of concern, information on the venom components, biological activity and pathological mechanisms are still scarce. Therefore, the aim of the present study was to investigate a serine protease component of jellyfish venom (NnV) and unveil its characteristics.

Anticancer Effect of Jellyfish Venom on HepG2 Cells and a Tumor Xenograft Animal Model.

Various kinds of animal venoms and their components have been widely studied for potential therapeutic applications. This study evaluated whether jellyfish venom (NnV) has anticancer activity. NnV strongly induced cytotoxicity of HepG2 cells through apoptotic cell death, as demonstrated by alterations of chromatic morphology, activation of procaspase-3, and an increase in the Bax/Bcl-2 ratio.

The Hair Growth-Promoting Effect of Houtt. Extract.

Houtt. is traditionally used as a medicinal plant to treat patients suffering from skin disease in Korea. However, the beneficial effect of Houtt.

Cloning a Chymotrypsin-Like 1 (CTRL-1) Protease cDNA from the Jellyfish Nemopilema nomurai.

An enzyme in a nematocyst extract of the Nemopilema nomurai jellyfish, caught off the coast of the Republic of Korea, catalyzed the cleavage of chymotrypsin substrate in an amidolytic kinetic assay, and this activity was inhibited by the serine protease inhibitor, phenylmethanesulfonyl fluoride. We isolated the full-length cDNA sequence of this enzyme, which contains 850 nucleotides, with an open reading frame of 801 encoding 266 amino acids. A blast analysis of the deduced amino acid sequence showed 41% identity with human chymotrypsin-like (CTRL) and the CTRL-1 precursor.

Nemopilema nomurai Jellyfish venom treatment leads to alterations in rat cardiomyocytes proteome.

This data article restrains data associated to the Choudhary et al. [1]. Nemopilema nomurai Jellyfish venom (NnV) can lead to cardiac toxicity.

Evaluation of Phototoxic and Skin Sensitization Potentials of PLA 2 -Free Bee Venom.

Bee venom (BV) from honey bee (Apis mellifera L.) has been used in oriental medicine and cosmetic ingredients because of its diverse pharmacological activities. In many studies, among BV components, phospholipase A2 (PLA2) is known as a major player in BV-induced allergic reaction.

Proteomics approach to examine the cardiotoxic effects of Nemopilema nomurai Jellyfish venom.

Unlabelled: Nemopilema nomurai is one of the largest species of jellyfish in the world. It blooms mainly offshore of Korea, China, and Japan. Increasing population numbers of N.

Improved Therapeutic Profiles of PLA2-Free Bee Venom Prepared by Ultrafiltration Method.

Bee venom (BV) has long been used in traditional Eastern and Western medicine for chronic inflammation, pain and skin therapy. Human exposure to BV, however, often causes unwanted adverse effects and is even fatal in some cases. Phospholipase A2 (PLA2) of BV is now suspected to play a key role in these adverse effects.
