BACKGROUND: Radiation therapy is commonly used to treat thoracic malignancies. However, it may lead to severe lung pneumonitis and ultimately fibrosis. Irradiation has been reported to increase epithelial-mesenchymal transition (EMT) of type II alveolar epithelial cells (AEC), which play an important role in pulmonary fibrosis. The transforming growth factor-β (TGF-β) and ERK/glycogen synthase kinase 3β (GSK3β) pathways are critically involved in radiation-induced EMT. In the present study, we investigated whether baicalin was a novel therapeutic candidate for radiation-induced EMT in type II AEC...

Baicalin and baicalein are flavonoid compounds derived from Scutellaria baicalensis Georgi. These compounds have been used in the treatment of numerous diseases, including fibrotic diseases. However, research regarding their antifibrotic effects and mechanism of action in renal fibrosis is limited. In the present study, normal rat kidney interstitial fibroblast (NRK-49F) cells were stimulated with transforming growth factor (TGF)-β1, with or without baicalin/baicalein, and assessed for proliferation, apoptosis, extracellular matrix (ECM) accumulation, collagen expression, TGF-β1 expression and mothers against decapentaplegic homolog 3 (SMAD3) protein activation...

Modular targeting is promising in drug research at network level, but it's challenging to quantificationally identify the precise On-modules. Based on a proposed Modudaoism (MD), we defined conserved MD (MDc) and varied MD (MDv) to quantitatively evaluate the conformational and energy variations of modules, and thereby identify the conserved and discrepant allosteric modules. Compared with the Zsummary , MDc/MDv got an optimized result of module preserved ratio and modular structure. In mice anti-ischemic networks, 3, 5, and 1 conserved allosteric modules as well as 4, 1, and 3 On-modules of baicalin (BA), jasminoidin (JA), and ursodeoxycholic acid (UA) were identified by MDc and MDv, 5 unique allosteric modules and their characteristic actions were revealed...

Posttraumatic stress disorder (PTSD) gains a lot of attention due to high prevalence and strong psychological upset, but the etiology remains undefined and effective treatment is quite limited. Growing studies demonstrated the involvement of oxidative stress in various psychiatry diseases, suggesting anti-oxidation therapy might be a strategy for PTSD treatment. Free and Easy Wanderer (FAEW) is a poly-herbal drug clinically used in China for hundreds of years in the treatment of psychiatric disorder. We hypothesized that FAEW exerts clinical effects through the activity against oxidative stress with fluoxetine as antidepressant control drug...

The radix of Scutellaria baicalensis (SB) is a herb widely used in traditional Chinese medicine to treat metabolic diseases. Several main components, including baicalin and wogonoside, possess anti-dyslipidemia, anti-obesity and anti-diabetic effects. We hypothesized that co-administration of SB extract and metformin exerts a better effect on obesity-induced insulin resistance and lipid metabolism than treatment with metformin alone. We compared the effect of metformin (100 mg/10 mL/kg/day) alone with co-administration of metformin (100 mg/5 mL/kg/day) and SB extract (200 mg/5 mL/kg/day) on Otsuka Long Evans Tokushima Fatty rats, a useful model of type II diabetes with obesity, and used Long-Evans Tokushima Otsuka rats as a control...

Previous studies have shown that compounds in the form of precipitate (CFP) from Huang-Lian-Jie-Du-Tang (HLJDT) were stable, and the CFP content reached 2.63% of the whole decoction and had good neuroprotective effects. However, there has been no research on their specific source. In this study, it was found that HLJDT CFP mainly came from the reaction of Scutellaria baicalensis and Coptis chinensis by studying the separated prescription components (accounting for 81.33% of HLJDT CFP). Unlike previous studies on HLJDT CFP, in this research the chemical composition of Scutellaria baicalensis-Coptis chinensis (SB-CC) CFP was identified by high performance liquid chromatography coupled with mass spectrometry (HPLC-MS(n)), which further proved that the main source of HLJDT CFP was Scutellaria baicalensis-Coptis chinensis CFP compared with previous HLJDT CFP studies...
