5-Aminolevulinic acid photodynamic therapy(ALA-PDT) has been widely used for cervical cancer treatment, but the mechanisms are still not fully delineated. Here we showed that ALA-PDT significantly upregulated HMGB1 while downregulated miR-34a expression levels in cervical cancer tissues, and the percentages of mature DCs(mDCs) were increased in ALA-PDT treated patients' peripheral blood. After treating HPV-positive Hela, SiHa, Caski and HPV-negative C33 A cervical cancer cell lines with ALA-PDT, HPV-positive cells' proliferative ability was significantly inhibited and apoptosis rates were elevated, while no significant changes were found in HPV-negative C33 A cell line...

BACKGROUND: Thromboses is a rapidly growing medical problem worldwide. Low-cost, high-scale production of thrombotic drugs is needed to meet the demand. The production of biomolecules in transgenic animals might help address this issue. To our knowledge, the expression of recombinant human plasminogen activator (rhPA) in goat mammary glands has never been reported before. METHODS: We constructed a mammary gland-specific expression vector, BLC14/rhPA, which encodes only the essential K2 fibrin-binding and P domains of wild-type tPA (deletion mutant of tPA lacking the F, E, and K1 domains), along with the goat β-lactoglobulin gene signal peptide-coding sequence...

Cervico-vaginal mucus (CVM), the product of epithelial cells lining the uterus, cervix and vagina, is secreted to facilitate uterine lubrication and microbial clearance. Predominantly composed of water and mucins, CVM also contains high levels of immuno-active proteins such as immunoglobulin A (IgA), lactoferrin and lysozyme which protect against infection by blocking adhesion and mediating microbial killing. The repertoire of cytokines, chemokines and antimicrobial peptides is predominantly generated by the secretions of endometrial epithelial cells into the uterine lumen and concentrated in the CVM...

Dendritic cells (DCs) harboring tumor-associated antigen are supposed to be a potential immunotherapy for hepatocellular carcinoma (HCC). Aspartate- β -hydroxylase (AAH), an overexpressed tumor-associated cell surface protein, is considered as a promising biomarker and therapeutic target for HCC. In this study, we constructed adenovirus vector encoding AAH gene by gateway recombinant cloning technology and preliminarily explored the antitumor effects of DC vaccines harboring AAH. Firstly, the total AAH mRNA was extracted from human HCC tissues; the cDNA was amplified by RT-PCR, verified, and sequenced after TA cloning...

Ovarian cancer is the leading cause of mortality resulting from gynecologic cancer. A common anti-ovarian tumor drug is cisplatin; however, repeated use of cisplatin causes severe resistance and leads to poor long-term survival rate in ovarian cancer patients. Recently, it was reported that lanthanum chloride (LaCl3 ) may inhibit tumor growth and induce apoptosis in certain cancer cells. In the present study, the effect of LaCl3 on ovarian cancer was determined in vivo and in vitro . A cisplatin-sensitive human ovarian cancer cell line, COC1, was used in the current study...

Adult neurogenesis is widespread among metazoans, it occurs in animals with a network nervous system, as cnidarians, and in animals with a complex and centralized brain, such as mammals, non-mammalian vertebrates, ecdysozoans, and a lophotrochozoan, Octopus vulgaris . Nevertheless, there are important differences among taxa, especially in the number of the regions involved and in cell proliferation rate during the life-cycle. The comparative evaluation of adult neurogenesis among different brain regions is an arduous task to achieve with only stereological techniques...

Desmosomes are the least understood intercellular junctions in the intestinal epithelia and provide cell-cell adhesion via the cadherins desmoglein (Dsg)2 and desmocollin (Dsc)2. We studied these cadherins in Crohn's disease (CD) patients and in newly generated conditional villin-Cre DSG2 and DSC2 knockout mice (DSG2ΔIEC ; DSC2ΔIEC ). CD patients exhibited altered desmosomes and reduced Dsg2/Dsc2 levels. The intestines of both transgenic animal lines were histopathologically inconspicuous. However, DSG2ΔIEC , but not DSC2ΔIEC mice displayed an increased intestinal permeability, a wider desmosomal space as well as alterations in desmosomal and tight junction components...

Phytophthora sojae is a destructive pathogen of soybean [Glycine max (L.) Merr.] causing stem and root rot to soybean plants worldwide. However, the pathogenesis and molecular mechanism of plant defense responses against P. sojae are largely unclear. Herein, we document the underlying mechanisms and function of a novel BTB/POZ protein in soybean, GmBTB/POZ, which contains a BTB/POZ domain found in certain animal transcriptional regulators, in host soybean plants in response to P. sojae. It is located in the cell nucleus and transcriptionally up-regulated by P...

The eye is a complex organ with a series of anatomical barriers that provide protection from physical and chemical injury while maintaining homeostasis and function. The physiology of the eye is multifaceted with dynamic flows and clearance mechanisms. This review highlights that in vitro ocular transport and metabolism models are confined by the availability of clinically relevant absorption, distribution, metabolism, and excretion (ADME) data. In vitro ocular transport models used for pharmacology and toxicity poorly predict ocular exposure...

Hepatocellular carcinoma (HCC) is one of the most commonly diagnosed malignancies worldwide with poor prognosis and tends to be hypervascular. Aberrant expression of the vascular endothelial growth factor 2 (VEGFR-2) has been implicated in the progression of HCC and represents a valid target for anticancer therapy. Apatinib, a small molecule inhibitor of VEGFR-2 tyrosine kinase, shows strong antitumor activity in various tumors. This study is designed to evaluate the activity of apatinib on both human umbilical vein vascular endothelial cells (HUVECs) and HCC cell lines (in vitro and in vivo), and also to investigate the characteristics and possible mechanisms underlying these effects by molecular biology methods...

The human neurotropic polyomavirus JC, JC virus (JCV), infects the majority of human population during early childhood and establishes a latent/persistent infection for the rest of the life. JCV is the etiologic agent of the fatal demyelinating disease of the central nervous system, progressive multifocal leukoencephalopathy (PML) that is seen primarily in immunocompromised individuals. In addition to the PML, JCV has also been shown to transform cells in culture systems and cause a variety of tumors in experimental animals...
