Recent reports have confirmed highest levels of growth hormone (GH) receptor (GHR) transcripts in melanoma, one of the most aggressive forms of human cancer. Yet the mechanism of GH action in melanoma remains mostly unknown. Here, using human malignant melanoma cells, we examined the effects of GH excess or siRNA mediated GHR knock-down (GHRKD) on tumor proliferation, migration and invasion. GH promoted melanoma progression while GHRKD attenuated the same. Western blot analysis revealed drastic modulation of multiple oncogenic signaling pathways (JAK2, STAT1, STAT3, STAT5, AKT, mTOR, SRC and ERK1/2) following addition of GH or GHRKD...

BACKGROUND: In a previously reported study, patients with regionally advanced melanoma were treated with neoadjuvant ipilimumab (ipi) (Tarhini in PLoS ONE 9(2): e87705, 3). Significant changes in circulating myeloid derived suppressor cells (MDSC), regulatory T cells (Treg) and peptide specific type I CD4(+) and CD8(+) T cells were noted at week 6 that correlated with clinical outcome. Characterization of antigen-specific effector T cell secreted cytokines may shed insights into ipi associated T cell activation and function...

Malaria liver stage infection is an obligatory parasite development step and represents a population bottleneck in Plasmodium infections, providing an advantageous target for blocking parasite cycle progression. Parasite development inside hepatocytes implies a gross cellular insult evoking innate host responses to counteract intra-hepatocytic infection. Using primary hepatocyte cultures, we investigated the role of Kupffer cell-derived hepatocyte growth factor (HGF) in malaria liver stage infection. We found that Kupffer cells from Plasmodium-infected livers produced high levels of HGF, which trigger apoptosis of infected hepatocytes through a mitochondrial-independent apoptosis pathway...

The number of elderly patients with spinal cord injury (SCI) is increasing worldwide, representing a serious burden for both the affected patients and the community. Previous studies have demonstrated that neural stem cell (NSC) transplantation is an effective treatment for SCI in young animals. Here we show that NSC transplantation is as effective in aged mice as it is in young mice, even though aged mice exhibit more severe neurological deficits after SCI. NSCs grafted into aged mice exhibited better survival than those grafted into young mice...

AIM: Anastomotic leak is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. We hypothesized that the infection-induced inflammatory response may induce overexpression of tumour progression-related genes in immune cells. The aim was to investigate the effect of postoperative intra-abdominal infection on the gene expression patterns of peripheral blood leukocytes (PBL) after surgery for colorectal cancer. METHODS: Prospective matched cohort study...

Hepatocyte growth factor (HGF) and MET are candidates of targeted therapies for cancer patients. Although MET and HGF are commonly expressed in biliary tract cancers, their expression and gene copy number status and their association with KRAS mutations have not been investigated in pancreatobiliary-type ampullary adenocarcinomas (A-ACs), one of the aggressive periampullary cancers. MET and HGF expressions and MET copy number status were examined by performing immunohistochemistry (IHC) and silver in situ hybridization (SISH) in 62 surgically resected, paraffin-embedded tumors, respectively...

C-Met is a receptor tyrosine kinase with multiple functions throughout embryonic development, organogenesis and wound healing and is expressed in various epithelia. The ligand of c-Met is Hepatocyte Growth Factor (HGF) which is secreted among others by mesenchymal stroma/stem (MSC) cells.Physiological c-Met functions are centred around processes that underly cellular motility and invasive growth. Aberrant c-Met expression and activity is observed in numerous cancers and makes major contributions to cell malignancy...

Previous studies in rat hepatocytes have shown that the MEK/ERK, PI3K/Akt and p38 pathways are all involved in the activation of DNA synthesis by EGF and that sustained activation of MEK/ERK is required. Here, we show that although HGF stimulated DNA synthesis and activated signaling in the same manner as EGF, the contribution of the signaling pathways to the induction of DNA synthesis differed. While HGF-induced DNA synthesis was dependent on MEK/ERK, with no significant contribution from PI3K/Akt, p38 suppressed HGF-induced DNA synthesis...

It has been reported that p21-activated kinase 4 (PAK4) is amplified in pancreatic cancer tissue. PAK4 is a member of the PAK family of serine/threonine kinases, which act as effectors for several small GTPases, and has been specifically identified to function downstream of HGF-mediated c-Met activation in a PI3K dependent manner. However, the functionality of PAK4 in pancreatic cancer and the contribution made by HGF signalling to pancreatic cancer cell motility remain to be elucidated. We now find that elevated PAK4 expression is coincident with increased expression levels of c-Met and the p85α subunit of PI3K...

Many tumors display intracellular heterogeneity, with subsets of cancer stem cells (CSC) that sustain tumor growth, recurrence, and therapy resistance. Cancer associated fibroblasts (CAF) have been shown to support and regulate CSC function. Here we investigated the interactions between CSCs and CAFs in mammary gland tumors driven by combined activation of Wnt/β-catenin and Hgf/Met signaling in mouse mammary epithelial cells. In this setting, CSCs secreted the hedgehog ligand SHH, which regulated CAFs via paracrine activation of Hedgehog signaling...

NG2-expressing neural progenitor cells (i.e., NG2 glial cells) maintain their proliferative and migratory activities even in the adult mammalian central nervous system (CNS) and produce myelinating oligodendrocytes and astrocytes. Although NG2 glial cells have been observed in close proximity to neuronal cell bodies in order to receive synaptic inputs, substantive non-proliferative roles of NG2 glial cells in the adult CNS remain unclear. In the present study, we generated NG2-HSVtk transgenic rats and selectively ablated NG2 glial cells in the adult CNS...

BACKGROUND: Anaplastic lymphoma kinase (ALK), which is a receptor tyrosine kinase, is essentially and transiently expressed in the developing nervous system. Recently, the deregulated expression of full-length ALK has been observed in some primary solid tumors, but little is known about its involvement in the tumorigenesis of uterine carcinosarcomas (UCSs). Here we examined the functional role of the ALK gene in UCSs. METHODS: Regulation and function of the ALK gene were assessed using two endometrial carcinoma cell lines...

The aim of the study was to identify significant abnormalities in angiogenic factor profiles occurring at early-stage non-small cell lung cancer (NSCLC). Contrary to the previous studies, our research included patients with only stage I NSCLC, which allowed for estimating the utility of circulating angiogenic factors in early NSCLC detection. The investigation was performed in serum samples collected from individuals with untreated NSCLC (n=41) and a matched control group of healthy individuals (n=61). All patients had histopathologically-confirmed stage IA or IB NSCLC...

BACKGROUND: Vascular endothelial growth factor (VEGF) promotes angiogenesis in vivo. We hypothesized that exogenous delivery of VEGF prior to bone marrow-derived endothelial precursor cell (EPC) transplantation may improve orthotopic liver transplantation (OLT)-induced hepatic ischemia-reperfusion injury (HIRI). METHODS: OLT between Sprague Dawley donor rats and inbred LEW Wistar recipient rats was performed in six experimental groups to comparatively assess the effects of VEGF gene: an untreated normal control group, a surgical control group, a liposomal control group, a VEGF group receiving only the liposome-encapsulated VEGF plasmid, an EPC group receiving only EPCs, and an EPC+VEGF group receiving the liposome-encapsulated VEGF plasmid followed by EPCs...

Mesenchymal stem cells (MSC) offer a novel approach to treatment of inflammatory disorders in humans and companion animals. Cats spontaneously develop a wide variety of inflammatory disorders and may potentially benefit from MSC-based therapies. Multiple genes are involved in immunomodulation by MSC and interspecies differences between expressions of these genes exist. The goals of the study were to characterize the expression of genes known to be involved in MSC-based immunomodulation and determine the effect of MSC on proliferation of T-cells in co-culture experiments with PBMC...
