BACKGROUND: Magnolin is the most active ingredient in the herb Magnolia fargesii, which has been traditionally used in oriental medicine to treat headaches and nasal congestion. Recent researches demonstrate that Magnolin inhibits cancer cell migration and invasion. MATERIALS AND METHODS: This study used cell culture and the BALB/c nu/nu mouse xenograft model to investigate whether or not magnolin can inhibit the growth of PC3 and Du145 prostate cancer cells. MTT assay and flow cytometry were performed to estimate the proliferation, cycle, and apoptosis of the cells in vitro...

Protein arginine N-methyltransferase 2 (PRMT2) functions in JAK-STAT and Wnt/β-catenin signaling pathways, serves as a nuclear receptor-dependent transcriptional co-activator, and represses NF-κB and E2F1 transcription factor activities to promote apoptosis. We have previously demonstrated that PRMT2 interacts with PRMT1 and increases its activity. Here, we reveal associations using proteomics between the PRMT2 SH3 domain and splicing factors including Src-associated in mitosis 68 kDa protein (SAM68), a PRMT1 substrate and trans-acting factor that mediates BCL-X alternative splicing...

Honokiol, derived from Magnolia officinalis, has various pharmacological properties. Platelet activation plays a critical role in cardiovascular diseases. Honokiol has been reported to inhibit collagen-stimulated rabbit platelet aggregation. However, detailed further studies on the characteristics and functional activity of honokiol in platelet activation are relatively lacking. In the present study, honokiol specifically inhibited platelet aggregation and Ca(+2) ion mobilization stimulated with collagen or convulxin, an agonist of glycoprotein (GP) VI, but not with aggretin, an agonist of integrin α2β1...

AML1-ETO is the most common oncoprotein leading to acute myeloid leukemia (AML), in which 5-year survival rate is only about 30%. However, currently there are no specific therapies for AML patients with AML1-ETO. Here, we report that AML1-ETO protein is rapidly degraded by Honokiol (HNK), a natural phenolic compound isolated from the plant Magnolia officinalis. HNK induced the degradation of AML1-ETO in a concentration- and time-dependent manner in leukemic cell lines and primary AML blasts with t(8;21) translocation...

Xylitol production from xylose by the yeast Candida magnoliae TISTR 5663 was enhanced by supplementing the fermentation medium with furfural (300mg/L) and glucose (3g/L with an initial mass ratio of glucose to xylose of 1:10) together under oxygen limiting conditions. In the presence of furfural and glucose, the final concentration of xylitol was unaffected relative to control cultures but the xylitol yield on xylose increased by about 5%. Supplementation of the culture medium with glucose alone at an initial concentration of 3g/L, stimulated the volumetric and specific rates of xylose consumption and the rate of xylitol production from xylose...

Despite the development of more advanced medical therapies, cancer management remains a problem. Head and neck squamous cell carcinoma (HNSCC) is a particularly challenging malignancy and requires more effective treatment strategies and a reduction in the debilitating morbidities associated with the therapies. Phytochemicals have long been used in ancient systems of medicine, and non-toxic phytochemicals are being considered as new options for the effective management of cancer. Here, we discuss the growth inhibitory and anti-cell migratory actions of proanthocyanidins from grape seeds (GSPs), polyphenols in green tea and honokiol, derived from the Magnolia species...

Counter-current chromatography (CCC) has been widely used as a preparative separation method to purify natural products from plant extracts and fermentation broths. Traditionally, throughput optimization in CCC has focused on sample concentration and sample volume. In this paper sample injection was considered as consisting of three variables: injection flow rate, post-injection flow rate and sample solvent. The effects of these parameters were studied using a honokiol purification from a Magnolia officinalis bark extract as a case study aiming to achieve the highest throughput/yield ratio for greater than 99% purity of this potential anti-cancer drug obtained for submission to the Chinese FDA...

Lung cancer is the leading cause of cancer death in the United States. Metastasis to lymph nodes and distal organs, especially brain, leads to severe complications and death. Preventing lung cancer development and metastases is an important strategy to reduce lung cancer mortality. Honokiol (HNK), a natural compound present in the extracts of magnolia bark, has a favorable bioavailability profile and recently has been shown to readily cross the blood-brain barrier. In the current study, we evaluated the antimetastatic effects of HNK in both the lymph node and brain mouse models of lung tumor metastasis...

Since implementation, the new UNOS OPTN kidney allocation system (KAS) has drastically expanded the pool of available kidneys to candidates that may have previously waited extended periods for an organ offer. This is particularly true for highly sensitized patients. The changes to the KAS have had ramifications throughout the transplant process, including for organ procurement organizations (OPO) and local transplant hospital call centers. Here, we will examine the impact of the new KAS on the organ donation process and highlight the necessary interactions between the OPO and transplant centers to best match donor kidneys and highly sensitized recipients...

Next-generation sequencing is empowering a deeper understanding of biology by enabling RNA expression analysis over the entire transcriptome with high sensitivity and a wide dynamic range. One powerful application within this field is stranded RNA sequencing (RNA-seq), which is necessary to distinguish overlapping genes and to conduct comprehensive annotation and quantification of long non-coding RNAs. Commonly used methods for generating strand-specific RNA-seq libraries are often complicated by protocols that require several rounds of enzymatic treatments and clean-up steps, making them time-intensive, insensitive, and unsuitable for processing several samples simultaneously...
