Dendrobium nobile protects against ovalbumin-induced allergic rhinitis by regulating intestinal flora and suppressing lung inflammation.

Antibiotic exposure-induced dysbiosis of the intestinal flora increases the risk of developing allergic rhinitis. Hence, regulating the balance of intestinal flora may be useful for preventing and treating allergic rhinitis. However, the underlying mechanism is unclear.

Yan-Hou-Qing formula attenuates allergic airway inflammation via up-regulation of Treg and suppressing Th2 responses in Ovalbumin-induced asthmatic mice.

Ethnopharmacological Relevance: Yan-Hou-Qing (YHQ), a Chinese medicine formula containing fourteen kinds of materials, has been designed for pharyngitis and cough treatment in Oriental medicine. In the present study, the anti-allergic effects and underlying mechanisms of YHQ in inhibition of airway hyper responsiveness (AHR) was explored in an ovalbumin (OVA)-induced allergic asthma mouse model.

Materials And Methods: BALB/c mice were sensitized by OVA and cholera toxin (CT) and challenged with OVA intranasally to induce allergic asthma mouse model.

The evolution of posttranscriptional regulation.

"DNA makes RNA makes protein." After transcription, mRNAs undergo a series of intertwining processes to be finally translated into functional proteins. The "posttranscriptional" regulation (PTR) provides cells an extended option to fine-tune their proteomes.

Structure of Schlafen13 reveals a new class of tRNA/rRNA- targeting RNase engaged in translational control.

Cleavage of transfer (t)RNA and ribosomal (r)RNA are critical and conserved steps of translational control for cells to overcome varied environmental stresses. However, enzymes that are responsible for this event have not been fully identified in high eukaryotes. Here, we report a mammalian tRNA/rRNA-targeting endoribonuclease: SLFN13, a member of the Schlafen family.

Global analysis of regulatory divergence in the evolution of mouse alternative polyadenylation.

Alternative polyadenylation (APA), which is regulated by both cis-elements and trans-factors, plays an important role in post-transcriptional regulation of eukaryotic gene expression. However, comparing to the extensively studied transcription and alternative splicing, the extent of APA divergence during evolution and the relative cis- and trans-contribution remain largely unexplored. To directly address these questions for the first time in mammals, by using deep sequencing-based methods, we measured APA divergence between C57BL/6J and SPRET/EiJ mouse strains as well as allele-specific APA pattern in their F1 hybrids.

GIT1 enhances neurite outgrowth by stimulating microtubule assembly.

GIT1, a G-protein-coupled receptor kinase interacting protein, has been reported to be involved in neurite outgrowth. However, the neurobiological functions of the protein remain unclear. In this study, we found that GIT1 was highly expressed in the nervous system, and its expression was maintained throughout all stages of neuritogenesis in the brain.

Asparagus polysaccharide and gum with hepatic artery embolization induces tumor growth and inhibits angiogenesis in an orthotopic hepatocellular carcinoma model.

Liver cancer is one of leading digestive malignancies with high morbidity and mortality. There is an urgent need for the development of novel therapies for this deadly disease. It has been proven that asparagus polysaccharide, one of the most active derivates from the traditional medicine asparagus, possesses notable antitumor properties.

Gastroprotective and anti-Helicobacter pylori potential of herbal formula HZJW: safety and efficacy assessment.

Background: A traditional Chinese Medicine (TCM) formula, HZJW, has been applied in clinics in China for gastrointestinal disorders. However, the therapeutic mechanism underlying its efficacy and safety remained to be defined. The present investigation was undertaken to evaluate the formula HZJW for its gastroprotective potential, possible effect on Helicobacter pylori along with safety to justify its anti-ulcer action and safe clinical application.

Sweet tea leaves extract improves leptin resistance in diet-induced obese rats.

Aim Of The Study: Dietary obesity is usually characterized by leptin resistance and abnormal lipid metabolism. Lithocarpus polystachyus Rehd.(Sweet Tea) leaf is a kind of Chinese folkloric medicine, and it has been widely used for obesity, diabetes, and hypertension in South China.

Expression level of beta-catenin is associated with prognosis of esophageal carcinoma.

Aim: To examine the association of beta-catenin with the clinicopathologic features and prognosis of esophageal squamous cell carcinoma (ESCC).

Methods: Beta-catenin mRNA expression level in 40 ESCC patients (28 males and 12 females, age range 38-82 years, median 60 years) was analyzed by real-time PCR. Beta-catenin mRNA expression levels in tumor cells were categorized as weaker (level 1) or equal to or stronger (level 2) than those in endothelial cells.

[Effect of external gastrin on apoptosis and expression of bcl-2 gene in gastric cancer cells].

Background & Objective: It has been reported that external gastrin could facilitate the growth of the cells of gastrointestinal carcinomas. However, the modifying effect of gastrin on apoptosis of the gastric carcinoma has not been well appreciated. This study was designed to investigate the modifying effect of gastrin on apoptosis of the stomach cancer cell.
