Bioactive daphnane diterpenes from the flower buds of (Thymelaeaceae).

Four diterpenes of the daphnane type were isolated from a methanol extract of the flower buds of , the two of them were new structures named genkwadanes J () and K (). Their structures were determined based on analysis of their 1D- and 2D-NMR, HRESIMS and ECD calculations. Among the isolates, the cytotoxicity was assessed the MTT method using the K562, MCF-7 and HeLa cancer cell lines, the positive control was taxol.

The complete chloroplast genome of (Ranunculaceae).

Thunb. 1784 is a plant with important medicinal values. Here we report its chloroplast genome.

Revealing disparities in different types of park visits based on cellphone signaling data in Guangzhou, China.

Urban parks play a crucial role in promoting the urban ecological environment and the health and well-being of dwellers. However, existing research on park visits and drivers has largely ignored the classification of parks. Using the four-level park system in Guangzhou as a case, this study first measured park visits based on cellphone signaling data.

Curcumin suppresses glioblastoma cell proliferation by p-AKT/mTOR pathway and increases the PTEN expression.

Background: Glioblastoma (GB) is the most common neoplasm in the brain. Curcumin, as a known polyphenolic compound extracted from turmeric, is a chemotherapy used in some cancer treatments in China. However, the effect of curcumin on the survivability of GB cells remains to be elucidated.

Captopril Attenuates the Upregulated Connexin 43 Expression in Artery Calcification.

Objective: Vascular calcification is commonly observed in atherosclerosis and diabetes. The renin-angiotensin II system is associated with the regulation of arterial stiffening. The aim of this study was to examine whether the angiotensin-converting enzyme inhibitors captopril attenuates artery calcification.

Vildagliptin and G-CSF Improved Angiogenesis and Survival after Acute Myocardial Infarction.

Background: Myocardial infarction (MI) is one of the most important diseases that has stimulated interest in understanding cardiac function recovery. SDF-1 is a chemotactic factor and a pro-angiogenic molecule; SDF-1 degradation is inhibited by dipeptidyl peptidase-4 (DPP4) inhibitors, such as vildagliptin. We investigated whether vildagliptin affects angiogenesis in MI and improves cardiac function recovery.

Lycorine inhibits glioblastoma multiforme growth through EGFR suppression.

Background: Lycorine has been revealed to inhibit the development of many kinds of malignant tumors, including glioblastoma multiforme (GBM). Although compelling evidences demonstrated Lycorine's inhibition on cancers through some peripheral mechanism, in-depth mechanism studies of Lycotine's anti-GBM effects still call for further exploration. Epidermal Growth Factor Receptor (EGFR) gene amplification and mutations are the most common oncogenic events in GBM.

Isomangiferin, a Novel Potent Vascular Endothelial Growth Factor Receptor 2 Kinase Inhibitor, Suppresses Breast Cancer Growth, Metastasis and Angiogenesis.

Purpose: Vascular endothelial growth factor (VEGF) signal transduction mainly depends on its binding to VEGF receptor 2 (VEGFR-2). VEGF downstream signaling proteins mediate several of its effects in cancer progression, including those on tumor growth, metastasis, and blood vessel formation. The activation of VEGFR-2 signaling is a hallmark of and is considered a therapeutic target for breast cancer.

Suppression of Non-Small Cell Lung Cancer Growth and Metastasis by a Novel Small Molecular Activator of RECK.

Background/aims: Reversion-inducing cysteine-rich protein with kazal motifs (RECK) is a novel tumor suppressor gene that is critical for regulating tumor cell invasion and metastasis. The expression of RECK is dramatically down-regulated in human cancers. Harmine, a tricyclic compound from Peganum harmala, has been shown to have potential anti-cancer activity.
