Ser-10 phosphorylation of histone H3 is revealed to be relative to chromosome condensation at prophase during mitosis. In this report, we demonstrate using immunofluorescence microscopy that the subcellular distribution of the Ser-10 phosphorylated histone H3 was similar to that characteristic of chromosomal passenger proteins during the terminal stages of(More)
In this study, indirect immunofluorescence labeling was used to examine the cellular dynamic distribution of Thr11 phosphorylated H3 at mitosis in MCF-7 cells. The Thr11 phosphorylation was observed beginning at prophase at centromeres. Upon progression of mitosis, fluorescence signal was enhanced in the central region of the metaphase plate and maintained(More)
Pancreatic cancer is a devastating disease with the worst prognosis among all the major human malignancies. The propensity to rapidly metastasize contributes significantly to the highly aggressive feature of pancreatic cancer. The molecular mechanisms underlying this remain elusive, and proteins involved in the control of pancreatic cancer cell motility are(More)
Paclitaxel is a microtubule-targeting agent widely used for the treatment of many solid tumors. However, patients show variable sensitivity to this drug, and effective diagnostic tests predicting drug sensitivity remain to be investigated. Herein, we show that the expression of end-binding protein 1 (EB1), a regulator of microtubule dynamics involved in(More)
Cell migration, a complex process critical for tumor progression and metastasis, requires a dynamic crosstalk between microtubules (MTs) and focal adhesions (FAs). However, the molecular mechanisms underlying this event remain elusive. Herein we identify the proto-oncogenic protein Src as an important player in the regulation of the MT-FA crosstalk. Src(More)
4-Vinyl-2, 6-dimethoxyphenol (canolol) is an antioxidant phenolic compound extracted from crude canola oil. In current research, K19-C2mE transgenic mice, developing hyperplastic tumors spontaneously in the glandular stomach, were used to study the mechanisms involved in the anti-inflammation and anti-tumor effects of canolol. Tg mice receiving canolol diet(More)
In this study, a three layered poly (ε-caprolactone) (PCL) graft (tPCL) was fabricated by electrospinning PCL and electrospraying poly (ethylene oxide) (PEO), which has a thin dense inner layer, a loose middle layer, and a dense outer layer. Regular PCL grafts (rPCL) with only a dense layer were used as control. In vivo evaluation was performed in rabbit(More)
The lack of efficient vascularization within frequently used poly(ε-caprolactone) (PCL) scaffolds has hindered their application in tissue engineering. Hydrophobin HGFI, an amphiphilic protein, can form a self-assembly layer on the surface of PCL scaffolds and convert their wettability. In this study, a fusion protein consisting of HGFI and vascular(More)
Nanoparticles (NPs) assembled from amphiphilic polycations have been certified as potential carriers for gene delivery. Structural modification of polycation moieties may be an efficient route to further enhance gene delivery efficiency. In this study two electroneutral monomers with different hydrophobicities, 2-hydroxyethyl methacrylate (HEMA) and(More)
CENP-A locates at nucleosome as histone H3-like proteins, and is phosphorylated during mitosis. We investigated the dynamic distribution of p-CENP-A to explore the details of its function. We found that p-CENP-A was phosphorylated at late prophase, and the signal of p-CENP-A arranged at equatorial plate along with nucleosomes at metaphase, but moved to(More)
