Paired-related homeobox 1 induces epithelial-mesenchymal transition in oesophageal squamous cancer.

Background: It is unclear that paired-related homeobox 1 (PRRX1) induces epithelial-mesenchymal transition (EMT) in oesophageal cancer and the specific function of PRRX1 in oesophageal cancer metastasis.

Aim: To assess the significance of PRRX1 expression and investigate the mechanism of EMT in oesophageal cancer metastasis.

Methods: Detect the expression of PRRX1 by immunohistochemistry in oesophageal tumour tissues and adjacent normal oesophageal tissues; the PRRX1 short hairpin RNA (shRNA) or blank vector lentiviral gene delivery system was transfected into cells; cell proliferation assay, soft agar colony formation assays, cell invasion and migration assays and animal studies were used to observe cells biological characteristics and ; XAV939 and LiCl were used to alter the activity of Wnt/β-catenin pathway.

Clinical significance of serum S100A10 in lung cancer.

Objective: To investigate the clinical significance of serum S100 calcium-binding protein A10 (S100A10) levels in lung cancer.

Methods: This prospective study enrolled patients with lung cancer, patients with benign lung nodules and healthy control subjects. Serum S100A10 levels and three biomarkers were measured and compared between the groups.

Sestrin 2 suppresses cells proliferation through AMPK/mTORC1 pathway activation in colorectal cancer.

Sestrin 2 is a conserved antioxidant protein that reduces reactive oxygen species (ROS) and inhibits mammalian target of rapamycin complex 1 (mTORC1). We previously showed that sestrin 2 is abnormally decreased in colorectal cancer (CRC). To elucidate the molecular mechanism behind the potential contribution of sestrin 2 to CRC, we used a lentiviral expression vector system to determine the effects of sestrin 2 overexpression on human CRC cells.

Decreased expression of sestrin 2 predicts unfavorable outcome in colorectal cancer.

Sestrin 2 is a conserved antioxidant protein that is involved in p53‑dependent antioxidant defenses and protects cells against oxidative stresses. The present study was conducted to examine the expression of sestrin 2 in colorectal cancer (CRC) and investigate a possible relationship between sestrin 2 expression and prognosis in CRC. The expression of sestrin 2 in human CRC tissues and cell lines was evaluated by immunohistochemical or immunofluorescent staining and western blot analysis.

High expression of CASK correlates with progression and poor prognosis of colorectal cancer.

Calcium/calmodulin-dependent serine protein kinase (CASK), which localizes at cell-cell adhesion sites and binds to the heparan sulfate proteoglycan syndecan-2, is involved in cell proliferation, cytoskeletal remodeling, and cell migration. To demonstrate the role of CASK in colorectal cancer (CRC) carcinogenesis, we examined the expression of CASK and its binding protein syndecan-2 in human CRC tissues. The expression of CASK was measured in CRC specimens and the controls from adenomas and normal mucosae by immunohistochemical staining and Western blot analysis.

2-Bromo-4-chloro-6-[(E)-o-tolyl-imino-meth-yl]phenol.

The title compound, C(14)H(11)BrClNO, is a Schiff base compound derived from the condensation of 3-bromo-5-chloro-salicyl-aldehyde and o-toluidine in methanol. The aromatic rings make a dihedral angle of 38.3 (1)°.

[Study on the interaction of hesperidin or icariin with lysozyme by fluorescence spectroscopy].

The interaction of hesperidin (HES) or icariin (ICA) and lysozyme (LYS) was studied by fluorescence spectroscopy in physiological buffer solution. It was observed that there was a strong fluorescence quenching effect of hesperidin or icariin on lysozyme. The quenching constants of the drugs with lysozyme were measured at different temperatures, and the quenching mechanism was suggested as dynamic quenching for HES-LYS system and both static and dynamic quenching for ICA-LYS system.
