The mandibular glands (MGs) of honeybee workers are vital for the secretion of lipids, for both larval nutrition and pheromones. However, knowledge of how the proteome controls MG development and functionality at the different physiological stages of worker bees is still lacking. We characterized and compared the proteome across different ages of MGs in(More)
Macroautophagy (autophagy) is an important factor affecting the function of vascular endothelial cells (VECs) and must be tightly regulated in these cells. However, the precise mechanisms underlying this process, particularly in the presence of serum, remain obscure. In this study, we identified trans-3,5,4'-trimethoxystilbene (TMS) as a potent small(More)
Royal jelly (RJ), secreted by honeybee workers, plays diverse roles as nutrients and defense agents for honeybee biology and human health. Despite being reported to be glycoproteins, the glycosylation characterization and functionality of RJ proteins in different honeybee species are largely unknown. An in-depth N-glycoproteome analysis and functional assay(More)
The hypopharyngeal gland (HG) in honeybee workers changes functions according to physiological age in the bee colony from producing royal jelly (RJ) in nurse bees to digestive enzymes in foragers. The same set of secretory cells expresses different genes or proteins to create these age-dependent changes; however, it is unknown precisely how the(More)
The worker and drone bees each contain a separate diploid and haploid genetic makeup, respectively. Mechanisms regulating the embryogenesis of the drone and its mechanistic difference with the worker are still poorly understood. The proteomes of the two embryos at three time-points throughout development were analyzed by applying mass spectrometry-based(More)
Vascular smooth muscle cells (VSMCs) are a major cell type of the arterial wall and their functionality is associated with blood pressure regulation. Although royal jelly (RJ) has reported effects on anti-hypertension, the mechanism of blood pressure regulation by major royal jelly protein 1 (MRJP1), the most abundant RJ protein, is still unknown. The mrjp1(More)
AIM To explore a simple and pragmatic method to obtain sufficient olfactory ensheathing cells from human fetal by using different attachment rates in harvested cells with the combinating of the technique of using NT3 intermittently. METHODS DMEM/F12 culture solution including 100 mL/L of fetal bovine serum or including NT3 was used to culture olfactory(More)
PURPOSE We aimed to explore the value of contrast-enhanced ultrasonography (CEUS) in guidance of percutaneous biopsy of anterior mediastinal lesions. METHODS Ninety patients with solitary anterior mediastinal lesions (55 males, 35 females; mean age, 46±4 years) were included. Patients were randomly divided into CEUS group (n=45) and conventional(More)
OBJECTIVE To explore the method for obtaining olfactory ensheathing cells from human fetal olfactory mucosa by cell culture for selective adhesion in the presence of neurotrophin-3 (NT3) and low-concentration serum. METHODS The olfactory ensheathing cells were cultured alternatively in DMEM/F12 culture medium containing 10% fetal bovine serum (FBS) and(More)
