SOCS3 Attenuates Dexamethasone-Induced M2 Polarization by Down-Regulation of GILZ via ROS- and p38 MAPK-Dependent Pathways.

Suppressors of cytokine signaling (SOCS) have emerged as potential regulators of macrophage function. We have investigated mechanisms of SOCS3 action on type 2 macrophage (M2) differentiation induced by glucocorticoid using human monocytic cell lines and mouse bone marrow-derived macrophages. Treatment of THP1 monocytic cells with dexamethasone (Dex) induced ROS generation and M2 polarization promoting IL-10 and TGF-β production, while suppressing IL-1β, TNF-α and IL-6 production.

NaHCO- and NaCl-Type Hot Springs Enhance the Secretion of Inflammatory Cytokine Induced by Polyinosinic-Polycytidylic Acid in HaCaT Cells.

Background: Background: Hot springs have been traditionally used as an alternative treatment for a wide range of diseases, including rheumatoid arthritis, bronchial asthma, diabetes, hypertension, psoriasis and atopic dermatitis. However, the clinical effects and therapeutic mechanisms associated with hot springs remain poorly defined.

Objective: The purpose of this study was to demonstrate the different effects of hot springs on cellular viability and secretion of inflammatory cytokines on keratinocyte in two geographically representative types of hot springs: NaHCO-type and NaCl-type, which are the most common types in South Korea.

Hispolon as an inhibitor of TGF-β-induced epithelial-mesenchymal transition in human epithelial cancer cells by co-regulation of TGF-β-Snail/Twist axis.

Hispolon (HPL), isolated from , has been used to treat various types of pathology, including inflammation, gastroenteric disorders, lymphatic diseases and numerous cancer subtypes. HPL has previously been reported to demonstrate a significant therapeutic efficacy against various types of cancer cells, including melanoma, leukemia, hepatocarcinoma, bladder and gastric cancer cells. However, its potential role in the epithelial-mesenchymal transition (EMT) has not been demonstrated.

Hydrophobically modified polysaccharide-based on polysialic acid nanoparticles as carriers for anticancer drugs.

This study presented the development of hydrophobically modified polysialic acid (HPSA) nanoparticles, a novel anticancer drug nanocarrier that increases therapeutic efficacy without causing nonspecific toxicity towards normal cells. HPSA nanoparticles were prepared by 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide (EDC)/N-hydroxysuccinimide (NHS) coupling between N-deacetylated polysialic acid (PSA) and 5β-cholanic acid. The physicochemical characteristics of HPSA nanoparticles (zeta-potential, morphology and size) were measured, and in vitro cytotoxicity and cellular uptake of PSA and HPSA nanoparticles were tested in A549 cells.

Shikonin as an inhibitor of the LPS-induced epithelial-to-mesenchymal transition in human breast cancer cells.

Shikonin (SK), a natural naphthoquinone isolated from the Chinese medicinal herb, has been known to suppress the proliferation of several cancer cells. However, its role in the epithelial mesenchymal transition (EMT) has yet to be demonstrated. The aim of the present study was to examine the effects of SK on EMT.

Suppression of LPS-induced epithelial-mesenchymal transition by aqueous extracts of Prunella vulgaris through inhibition of the NF-κB/Snail signaling pathway and regulation of EMT-related protein expression.

Epithelial-mesenchymal transition (EMT) is a pivotal event in the invasion and metastasis of cancer cells. Prunella vulgaris (PV) inhibits the proliferation of various cancer cells; however, its possible role in EMT has not been demonstrated. In the present study, we explored the effect of PV aqueous extract (PVAE), a typical medicine for decoction, on EMT.

Aqueous extract of Psoralea corylifolia L. inhibits lipopolysaccharide-induced endothelial-mesenchymal transition via downregulation of the NF-κB-SNAIL signaling pathway.

The epithelial-mesenchymal transition (EMT) is a pivotal event in the invasion and metastasis of cancer cells. Psoralea corylifolia L. (PC) inhibits the proliferation of various cancer cells.

Hispolon inhibits the growth of estrogen receptor positive human breast cancer cells through modulation of estrogen receptor alpha.

Human estrogen receptor α (ERα) is a nuclear transcription factor that is a major therapeutic target in breast cancer. The transcriptional activity of ERα is regulated by certain estrogen-receptor modulators. Hispolon, isolated from Phellinus linteus, a traditional medicinal mushroom called Sanghwang in Korea, has been used to treat various pathologies, such as inflammation, gastroenteric disorders, lymphatic diseases, and cancers.
