OBJECTIVE: In recent years, microRNAs have been identified to participate in tumor genesis and progression of different tumors including gastric cancer. However, the role of miR-377 played in gastric cancer (GC), and its mechanisms have not been demonstrated. PATIENTS AND METHODS: We detected miR-377 expression level in 86 GC and adjacent normal tissue samples by quantitative reverse transcription PCR (qRT-PCR) as well as in GC cell lines. The relationship between miR-377 and clinical pathological features was analyzed...

Microorganisms killing by dendritic cells (DCs) is an important effector mechanism during innate immune response, as it can avoid dissemination of infection during migration of these cells toward draining lymph nodes. However, this function depends on pattern recognition receptors (PRRs) to which the microorganism will bind in these cells. Regarding this, TLR9 activation, by stimulating the oxidative metabolism, induces increase in microbicidal activity of these cells. Accordingly, we showed that DCs treatment with a TLR9 agonist results in an increase in fungicidal activity of these cells against the fungus Paracoccidioides brasiliensis (Pb), which however, was not associated to higher H2O2 levels...

Zuotin-related factor 1 (ZRF1) is a recently characterized epigenetic factor involved in transcriptional regulation and is highly overexpressed in several malignancies, but it is not known whether it plays a role in gastric cancer (GC). In this study, we investigated whether ZRF1 acts as a cancer-promoting gene through its activation/overexpression in GC. We analyzed five GC cell lines and 133 primary tumors, which had been curatively resected in our hospital between 2001 and 2003. Overexpression of ZRF1 was detected in GC cell lines (four out of five lines, 80...

Ganciclovir (GCV) has been implicated in the development of testicular alterations. Exposure on gestational day (GD) 10 in rats induced permanent effects, including focal reduction or absence of germ cells (Sertoli cell-only tubules). Because the timing of exposure can be critical for testicular effects, we exposed rat dams to 300 mg/kg GCV (three 100mg/kg subcutaneous injections) on GD10, 14 and 19, when germ cells have high rates of migration, proliferation and are mitotically quiescent, respectively. Males exposed to GCV in utero on GD10 and 14 were evaluated for androgenization markers, serum and fecal androgens, and testicular histomorphometry at adulthood...

Folding of the cerebral cortex during brain development is a complex process that depends on the orchestrated action of a number of factors, including generation and proliferation of basal progenitor cells, and the radial migration of neurons. Patterns of primary cortical folding are stereotyped between individuals and across phylogeny, reflecting a strong genetic regulation of the underlying cellular mechanisms. Here we summarize recent findings on cellular and genetic mechanisms regulating this fascinating process that underlies expansion and functional complexification of the mammalian cerebral cortex...

The anticancer properties of ursolic acid (UA) and metformin (Met) have been well demonstrated. However, whether these compounds can act synergistically to prevent and treat cancer is not known. We present in this study, the synergism between UA and Met, and that of a new codrug made of UA and Met (UA-Met) against several cancer cell lines. The combination of high concentration of UA (25, 50, 75, 100 μM) and Met (5, 10, 20, 40 mM) resulted in synergetic cytotoxicity on MDA-MB-231 and MCF-7 cells (CI < 0...

Photodynamic therapy (PDT) has been indicated for oral squamous cell carcinoma (OSCC) at early stages. Chemo and radio-resistance are frequently observed in OSCC, but it is unknown whether this tumor can develop resistance to PDT. It was investigated the process of acquiring resistance to multiple cycles of PDT by using OSCC cells. We also analyzed the expression of anti-apoptotic proteins and those related to Akt/mTOR pathway. Sub-lethal doses of PDT were applied, consisting of a constant concentration of 5-aminolevulinic acid (5-ALA) (1 mM, 4-hour incubation) and increasing irradiation dose with LED (from 5...

Hepatocellular carcinoma (HCC) is the most common primary tumor of the liver and the sixth most common lethal cancer worldwide. Recent evidences demonstrated that oxidored nitro domain containing protein 1(NOR1), a putative tumor suppressor gene, is overexpressed in human HCC tissues. However, the role of NOR1 in HCC development remains unclear. Here, we described that NOR1 protein level is elevated in HCC and is associated with poorer clinical outcome. However, ecotopic overexpression of NOR1 protein in human HCC cell line HepG2 cells had no effect on cells proliferation, migration and clonality...

Increasing evidence highlights the important role of XIST, a long non-coding RNA (lncRNA), in the regulation of multiple cancers. However, the underlying mechanism of XIST in human hepatocellular carcinoma (HCC) still remains to be explored. Herein, intended to investigate the functional role of XIST in HCC initiation and progression. We first detected that XIST was significantly upregulated in HCC tissues and associated with tumor size and vascular invasion. Gain- and loss-of-function of XIST further presented that XIST promoted the progression of HCC cells, including proliferation, migration, and invasion...

Mesenchymal stem cells (MSCs), also known as stromal mesenchymal stem cells, are multipotent cells, which can be found in many tissues and organs as bone marrow, adipose tissue and other tissues. In particular MSCs derived from Adipose tissue (ADSCs) are the most frequently used in regenerative medicine because they are easy to source, rapidly expandable in culture and excellent differentiation potential into adipocytes, chondrocytes and other cell types. Acetylcholine (ACh), is one of the most important neurotransmitter in central (CNS) and peripheral nervous system (PNS), playing important roles also in non-neural tissue, but its functions in MSCs are still not investigated...

Long non-coding RNAs (lncRNAs) are emerging as important players in regulation of gene expression in higher eukaryotes. DDX5/p68 RNA helicase protein which is involved in splicing of precursor mRNAs also interacts with lncRNAs like, SRA and mrhl, to modulate gene expression. We performed RIP-seq analysis in HEK293T cells to identify the complete repertoire of DDX5/p68 interacting transcripts including 73 single exonic (SE) lncRNAs. The LOC284454 lncRNA is the second top hit of the list of SE lncRNAs which we have characterized in detail for its molecular features and cellular functions...

Melanoma is the leading cause of skin cancer deaths in the United States, and its incidence has been rising steadily for the past 30 years (Aftab et al, 2014). A more complete understanding of the molecular mechanisms that drive melanomagenesis is crucial to improve diagnosis, prognostication, and treatment of this disease. Given that melanoma survival rates are better when the disease is detected early, precise diagnostic tests for early melanoma detection would be extremely useful. In addition, as survival rates decrease drastically when the disease becomes metastatic, improved tools to more precisely identify high-risk patients as well as to predict treatment response are necessary...

Syndecans (SDCs) are a family of heparan sulfate proteoglycans (HSPGs) glycoproteins ubiquitously expressed on the cell surfaces and extracellular matrix of all mammalian tissues. There are four mammalian syndecans, SDC-1 thorough 4, which play a critical role in cell adhesion, migration, proliferation, differentiation, and angiogenesis through independent and growth factor mediated signaling. An altered expression of SDCs is often observed in autoimmune disorders, cancer, HIV infection, and many other pathological conditions...

Curcumin is the main curcuminoid found in turmeric rhizomes and is a strong candidate to formulate foodstuff with specific properties. Among various bioactive properties of curcumin, its antiinflammatory activity is remarkable; on the other hand, its low water solubility leads to low absorption. Thus, new formulations need to be developed to improve its efficacy, and encapsulation is a promising alternative strategy in this regard. The objective of the present study was to obtain curcumin-loaded polyvinylpyrrolidone (PVP) nanoparticles and evaluate their acute in vivo antiinflammatory activity...
