Abstract
Osteoarthritis (OA) is the most common disease of arthritis, a chronic joint disease that is always correlated with massive destruction such as cartilage destruction, inflammation of the synovial membrane, and so on. This study aims to explore the role of long noncoding RNA (lncRNA) LOC101928134 in the synovial hyperplasia and cartilage destruction, more specifically, in the Janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling pathway in an OA rat model. Microarray-based gene expression analysis was conducted to screen out the lncRNA differentially expressed in OA and predict the target gene of the lncRNA with the involvement of the signaling pathway through Kyoto encyclopedia of genes and genomes (KEGG) analysis. A model of OA was established and treated with the small interfering RNA LOC101928134/inhibitor of JAK/STAT signaling pathway to investigate the relationship among LOC101928134, IFNA1, and the JAK/STAT signaling pathway in OA. The effect of LOC101928134 on the serum levels of IFNA1, interleukin-1β, and tumor necrosis factor-α, and the apoptosis of synovial and cartilage cells was evaluated. LOC101928134, which was found to be highly expressed in knee joint synovial tissues of OA rats, regulated the expression of IFNA1 gene and inhibited JAK/STAT signaling pathway. Downregulation of LOC101928134 resulted in reduced knee joint synovitis, relived inflammatory damage, and knee joint cartilage damage of OA rats. Besides, synovial cell apoptosis was enhanced upon LOC101928134 downregulation, while cartilage cell apoptosis of OA rats was suppressed. These results demonstrate that downregulation of LOC101928134 suppresses the synovial hyperplasia and cartilage destruction of OA rats via activation of JAK/STAT signaling pathway by upregulating IFNA1, providing a new candidate for the treatment of OA.

Abstract
Different approaches have been used to study the pattern of cytokines in celiac disease (CD). Laser capture microdissection (LCM) is a powerful tool for the isolation of specific tissue compartments. We aimed to investigate the mucosal immune response that takes place in different intestinal compartments of CD patients, dissected by LCM, analyzing cytokine expression profile. Frozen section of jejunum was obtained from 15 untreated CD and 15 control. Surface epithelium and lamina propria compartment were isolated by LCM. RNA from each LCM sample was extracted and, after a retrotranscription step, messenger RNA levels for MxA, IL-15, TNF-α, IFN-γ, IL-17α, IL-21, IL-10, and TGF-β were determined by quantitative reverse transcriptase-PCR. Increased gene expression levels of MxA, IL-15, TNF-α, IL-10, and TGF-β was observed in the surface epithelium of untreated CD with respect to control. Furthermore, all the cytokines investigated were upregulated in the lamina propria of untreated CD as compared to control. Within the untreated CD group the expression of IL-15 was higher, in the surface epithelium than in the lamina propria, whereas the expression levels of IL-17 and IL-21 were higher in the lamina propria than in the surface epithelium. Finally, high levels of IL-10 and TGF-β were detected in both compartments of untreated CD biopsies. In CD, surface epithelium and lamina propria compartments, play a prominent role in determining innate and adaptive immunity, respectively. Conversely, surface epithelium and lamina propria produce high levels of anti-inflammatory cytokines, suggesting that both compartments are involved in the immunoregulatory response.

Abstract
Heme oxygenase (HO) plays a critical role in attenuating the production of reactive oxygen species through its ability to degrade heme in an enzymatic process that leads to the production of equimolar amounts of carbon monoxide and biliverdin/bilirubin and the release of free iron. The present review examines the beneficial role of HO-1 (inducible form of HO) that is achieved by increased expression of this enzyme in renal tissue. The influence of the HO system on renal physiology, obesity, vascular dysfunction, and blood pressure regulation is reviewed, and the clinical potential of increased levels of HO-1 protein, HO activity, and HO-derived end products of heme degradation is discussed relative to renal disease. The use of pharmacological and genetic approaches to investigate the role of the HO system in the kidney is key to the development of therapeutic approaches to prevent the adverse effects that accrue due to an impairment in renal function.

Abstract
OBJECTIVE To optimize transduction efficiency of mobilized CD34(+) cells with serotype-5 adenoviruses (Ad5s), we investigated the activity of the chemical cocktail BoosterExpress Reagent in enhancing Ad5-mediated gene transfer into CD34(+) cells. METHODS Enriched CD34(+) cells were transduced with three different Ad5s at increasing multiplicity of infections (MOIs) in the presence and absence of BoosterExpress Reagent. Percentages of transduced cells and levels of transgene expression were quantified by flow cytometry. Propidium iodide staining and colony growth were used to assess the toxicity of the transduction protocol. Expression of adenovirus receptors was investigated by flow cytometry. RESULTS Irrespective of the Ad5 used, transduction with BoosterExpress Reagent using an MOI of 500 resulted in an average six- to seven-fold increase of transduction efficiencies and 1.5- to 2-fold increase of the levels of transgene expression, which could be detected up to 7 days post-transduction. Although BoosterExpress Reagent alone did not affect the plating efficiency of CD34(+) cells, adenovector transduction plus BoosterExpress Reagent significantly reduced the plating efficiency due to the marked increase of transduced cells. However, adenoviral transduction in the presence of BoosterExpress Reagent failed to significantly reduce the recovery of CD34(+) cells as compared with transduction in the absence of the compound. Coxsackievirus and adenovirus receptor as well as alpha(v)beta(3), alpha(v)beta(5), alpha(5), and beta(1) integrins were upregulated by BoosterExpress Reagent. CONCLUSIONS BoosterExpress Reagent allows high-levels of durable transgene expression, thus making CD34(+) cells a suitable target for Ad5-mediated gene transfer.

Abstract
Efficient gene transfer with adenoviral type 5 (Ad5) vectors depends on the initial attachment of their fiber, which binds the coxsackie-adenovirus receptor (CAR), and their subsequent internalization, mediated by the interaction of viral penton base with target cell alphav integrins. We previously demonstrated that human leukemic cells lack these receptors and are therefore resistant to Ad5 transduction, limiting efforts to genetically modify these cells. Human leukemic blasts are, however, susceptible to transduction with an adenovector made CAR independent by substitution of a chimeric Ad5/35 fiber [Yotnda et al. (2001). Gene Ther. 8, 930-937]. Other receptors can also be targeted with recombinant ligand moieties incorporated into adenovirus fiber. We have determined which of these fiber-modified adenovectors is most effective at modifying human primary leukemia cells, and lines. We used a replication-incompetent Ad5-beta-gal vector, in which the Ad5 fiber was replaced with fiber from various adenovirus serotypes (Ad35 and Ad11), or modified either with variable length polylysine (K4, K7, K21) or RGD-4C peptide. All the modified fiber vectors transduced primary leukemia cells and cell lines more efficiently than Ad5. Polylysine-substituted Ad5F/K21 and peptide-modified Ad5F/RGD vectors were most effective overall (up to 100% efficiency), whereas Ad5F/RGD was the most effective at transducing B cell acute lymphoblastic leukemia cells (90% efficiency). Ad5F/K21 and Ad5F/RGD should be of value for the genetic modification of human primary leukemia cells.

Abstract
Using a nonviral, electroporation-based gene transfection approach, we demonstrate the efficient and consistent transfection of two poorly immunogenic tumor cell lines: B16F10 melanoma and renal carcinoma (RENCA). Three genes, IL-12, angiostatin (AS), and an endostatin:angiostatin fusion protein (ES:AS) were subcloned into a DNA plasmid containing EBNA1-OriP, which was then transfected into B16F10 and RENCA cells. Significant levels of protein were secreted into the culture supernatants of transfected cells in vitro. Transfected tumor cells were injected subcutaneously into mice. All the three transgenes were capable of significantly delaying and reducing the formation of primary B16F10 and RENCA tumors, as well as B16F10 lung metastases. By day 11 post-injection, all control mice that received either mock-transfected or empty vector DNA-transfected B16F10 tumor cells had developed large primary tumors. In contrast, mice that received IL-12-transfected B16F10 cells did not develop appreciable tumors until day 17, and these were significantly smaller than controls. Similar results were observed for the RENCA model, in which only one of the IL-12 mice had developed tumors out to day 31. Expression of AS or ES:AS also significantly delayed and reduced primary tumors. Overall, ES:AS was more effective than AS alone. Furthermore, 25% of the AS mice and 33% of the ES:AS mice remained tumor-free at day 17, by which point all control mice had significant tumors. Mouse survival rates also correlated with the extent of tumor burden. Importantly, no lung metastases were detected in the lungs of mice that had received either AS or ES:AS-transfected B16F10 tumor cells and significantly fewer metastases were found in the IL-12 group. The consistency of our transfection results highlight the feasibility of directly electroporating tumor cells as a means to screen, identify, and validate in vivo potentially novel antiangiogenic and/or antineoplastic genes.

Abstract
Present cancer gene therapy using proapoptotic genes has had limited success because the therapy is prone to cause side effects as a result of the lack of tissue and cancer specificity. To target cancer cells without damaging normal cells, we have designed a novel dual promoter system in which a tissue-specific transcription system under the control of a cancer-specific promoter drives expression of a therapeutic gene. The applicability of this system was demonstrated by adapting it to target lung cancer. We termed this lung cancer system TTS (TTF1 gene under the control of human telomerase reverse transcriptase promoter and human surfactant protein A1 promoter). The TTS system showed much higher promoter activity in lung cancer cells compared with other kinds of cancer and normal lung cells, including stem cells. Moreover, insertion of negative glucocorticoid responsive elements in the system allows it to be drug controllable. The approaches that we have used could be adapted to target other types of cancer. We report a novel cancer-targeted tissue-specific dual promoter system designed for gene therapy.

Abstract
Using a binary adenoviral system, we recently showed that the human telomerase reverse transcriptase (hTERT) promoter induces tumor-specific Bax gene expression. However, the strong cytotoxicity of Bax and other pro-apoptotic genes to packaging 293 cells has so far hindered construction of the desired single adenoviral vectors expressing toxic genes. We report here the construction of a single bicistronic adenoviral vector for tumor-specific Bax expression. The vector (Ad/gBax) utilizes the Tet-Off system and expresses a GFP/Bax fusion protein for easy detection. The hTERT promoter drives the expression of tTA, a transactivator capable of binding to TRE (tetracycline-responsive element) in the absence of tetracycline, which in turn induces expression of the GFP-Bax gene. The addition of tetracycline in 293 cells blocks the binding of tTA to TRE and substantially inhibits GFP-Bax expression and toxicity, thus allowing the packaging and production of Ad/gBax. Our data show that Ad/gBax could drive the high expression of GFP-Bax in tumor cells but not in normal cells and mouse tissues. Furthermore, the expression of GFP-Bax fusion protein elicited tumor-specific apoptosis in a variety of human cancer cells in vitro and in vivo at a level comparable to that induced by the binary system. Thus, Ad/gBax may become a potent therapeutic agent for the treatment of cancers.

Abstract
Inducible synthesis and secretion of therapeutic proteins following gene transfer could be a viable strategy to deliver biopharmaceuticals that currently require parenteral administration. Evaluating the protein pharmacokinetics and biological responses generated by different delivery modalities will provide a better understanding of the advantages and disadvantages of each strategy. The interferon-alpha (IFN-alpha) family of proteins, used clinically for infectious and malignant diseases, has a short half-life, and IFN-alpha therapy requires frequent administration of the drug by injection. Subcutaneous xenograft tumors were inhibited by weekly administration of polyethylene glycol modified (PEGylated) IFN-alpha protein or by a single administration of an adenovirus constitutively expressing IFN-alpha (IACB). Both treatment modalities inhibited tumor growth in a dose-dependent manner, suggesting that increasing exposure to IFN-alpha could result in effective tumor control. A single adenovirus that encodes the components necessary for tetracycline induction (IADR) expressed IFN-alpha in a ligand-dependent manner. Adding doxycycline to the drinking water of mice treated intravenously with the inducible adenovirus IADR inhibited tumor growth by 85% compared with mice that were not given doxycycline. The correlation between serum IFN-alpha concentration and the degree of tumor growth inhibition did not depend on the delivery technology used. It is likely that it will be feasible to control expression of IFN-alpha by oral administration of small molecule drugs after gene delivery to induce therapeutic concentrations of proteins.

Abstract
We recently showed that the human telomerase reverse transcriptase (hTERT) promoter induces tumor-specific Bax gene expression and selectively kills various human cancer cells both in vitro and in xenograft tumors. However, it remains unclear whether the hTERT promoter can be used to induce transgene expression in syngenic tumors in mice and whether Bax gene expression driven by the hTERT promoter will cause long-term, stem cell-related toxicity. To address these questions, we tested hTERT promoter-driven, adenovirus-mediated Bax transgene expression in an established syngenic mouse tumor model and its effects on tumor and normal murine tissues. The hTERT promoter was highly active in several murine tumor cell lines and a transformed cell line, but not in non-transformed and normal murine cell lines. The hTERT promoter induced tumor-specific Bax gene expression in mouse UV-2237m fibrosarcoma cells both in vitro and in vivo and suppressed syngenic tumor growth in immune-competent mice with no obvious acute or long-term toxic effects. Moreover, hTERT promoter-driven transgene expression in human CD34(+) bone marrow progenitor cells had effects similar to those observed in other normal human cells, suggesting that the hTERT promoter is much less active in CD34(+) cells than in tumor cells. Together, our data demonstrate that the hTERT promoter may allow the use of proapoptotic genes for cancer treatment without noticeable effects on progenitor cells.

Abstract
The expression level of the coxsackievirus and adenovirus receptor (CAR) gene in human cervical cancer cell lines (Hela, Caski, HT-3, and SiHa) appears to be correlated with their susceptibility to adenoviral vector-based gene transfer. Hela, Caski, and HT-3 cells, which express the CAR molecule on the cell surface, showed a higher susceptibility to infection of AdCMVGFP than SiHa cells with no detectable level of CAR expression. Transient expression of the CAR gene in SiHa cells dramatically enhanced the susceptibility to adenoviral infection. Furthermore, SiHa-CAR, a stable transfectant which expresses the CAR gene showed a highly increased susceptibility to adenoviral infection in contrast to SiHa. These results demonstrate that the low susceptibility of SiHa to adenoviral infection is closely related to its loss of the CAR gene expression. In addition, the low infection efficacy can be overcome by the ectopic expression of the CAR gene. These results also give insight into a possible application of the CAR gene to adenovirus-mediated gene delivery.

Abstract
Efficient infection with adenovirus (Ad) vectors based on serotype 5 (Ad5) requires the presence of coxsackievirus-adenovirus receptors (CAR) and alpha(v) integrins on cells. The paucity of these cellular receptors is thought to be a limiting factor for Ad gene transfer into hematopoietic stem cells. In a systematic approach, we screened different Ad serotypes for interaction with noncycling human CD34(+) cells and K562 cells on the level of virus attachment, internalization, and replication. From these studies, serotype 35 emerged as the variant with the highest tropism for CD34(+) cells. A chimeric vector (Ad5GFP/F35) was generated which contained the short-shafted Ad35 fiber incorporated into an Ad5 capsid. This substitution was sufficient to transplant all infection properties from Ad35 to the chimeric vector. The retargeted, chimeric vector attached to a receptor different from CAR and entered cells by an alpha(v) integrin-independent pathway. In transduction studies, Ad5GFP/F35 expressed green fluorescent protein (GFP) in 54% of CD34(+) cells. In comparison, the standard Ad5GFP vector conferred GFP expression to only 25% of CD34(+) cells. Importantly, Ad5GFP transduction, but not Ad5GFP/F35, was restricted to a specific subset of CD34(+) cells expressing alpha(v) integrins. The actual transduction efficiency was even higher than 50% because Ad5GFP/F35 viral genomes were found in GFP-negative CD34(+) cell fractions, indicating that the cytomegalovirus promoter used for transgene expression was not active in all transduced cells. The chimeric vector allowed for gene transfer into a broader spectrum of CD34(+) cells, including subsets with potential stem cell capacity. Fifty-five percent of CD34(+) c-Kit(+) cells expressed GFP after infection with Ad5GFP/F35, whereas only 13% of CD34(+) c-Kit(+) cells were GFP positive after infection with Ad5GFP. These findings represent the basis for studies aimed toward stable gene transfer into hematopoietic stem cells.

Abstract
Human interferon-alpha (IFN-alpha) has been used in the management of leukemia, but its diverse adverse effects may influence the ability of IFN-alpha to treat this disease. We constructed two retroviral vectors, LSN-IFN-alpha and LNC-IFN-alpha, in which IFN-alpha cDNA was driven by viral LTR and CMV promoters, respectively. After transduction into the PA317 and PG13 retroviral packaging cells, high titers of retrovirus were produced and were used to infect K562 and human BM CD34+ hematopoietic cells. The IFN-alpha gene expression in transduced K562 cells was confirmed by Northern blot, RT-PCR, RIA, and biologic assay. Cell proliferation and cell viability in IFN-alpha-transduced K562 cells were significantly suppressed as compared with control K562 cells. Although the IFN-alpha expression in K562 cells did not affect BCR/ABL expression, it apparently upregulated the production of adhesion molecules (VLA-4 and Mac-1). We evaluated the effect of IFN-alpha gene transfer on human CD34+ cells infected with LSN-IFN-alpha retrovirus with the aid of fibronectin (FN) fragment CH-296 and growth factors. RIA showed that IFN-alpha-transduced CD34+ cells produced 72.2+/-15 U/ml of IFN-alpha compared with 4.3+/-1.2 U/ml in control CD34+ cells. Methylcellulose clonogenic assay indicated that IFN-alpha-transduced CD34+ cells produced similar numbers of burst-forming units-erythrocytes (BFU-E)/colony-forming units-GM (CFU-GM) colonies as compared with control CD34+ cells. Selected colonies expressed IFN-alpha and neo(r) mRNA, as measured by RT-PCR. These studies indicate that retrovirus-mediated IFN-alpha gene transfer may provide a useful tool for studying the effect of IFN-alpha gene transfer on leukemic cells and long-lived CD34+ cells.

Abstract
To achieve long-term expression of human interferon alpha-5 (IFNalpha) gene in the bone marrow (BM) hematopoietic microenvironment, replication-deficient retroviral vector LSN-IFNalpha was used to deliver the IFNalpha gene into human BM CD34+ cells. After fibronectin-facilitated transduction, a fraction of CD34+ cells was plated in methylcellulose medium with or without G418 to assess transduction efficiency and the effect of IFNalpha gene transfer on colony formation. Colony-forming assay in the presence of G418 (400 microg/mL) revealed that 41% CFU-GM colonies are G418 resistant after infection with LSN-IFNalpha retrovirus. There was no significant difference in CFU-GM/BFU-E colony formation among IFNalpha gene-transduced CD34+ cells, control vector (LXSN) transduced-CD34+ cells and nontransduced CD34+ cells. Another portion of CD34+ cells was grown in liquid medium to measure IFNalpha production. RIA revealed that IFNalpha gene-transduced CD34+ cells produced 72.2 +/- 15.4 U/mL (10(6) cells/24 hours) of IFNalpha compared with 8.3 +/- 2.1 U/mL and 4.3 +/- 1.2 U/mL in LXSN-transduced or nontransduced CD34+ cells, respectively. The remaining portion of transduced CD34+ cells was transplanted into immunodeficient (NOD/SCID) mice to allow analysis of long-term expression of IFNalpha. Transplantation of 1x10(6) CD34+ cells into sublethally irradiated NOD/SCID mice showed that IFNalpha and neo(r) mRNA were detectable in engrafted mouse BM cells for up to 6 months. We conclude that continual local expression of IFNalpha in transduced CD34+ cells does not impair either CD34+ cell growth and differentiation or engraftment and long-term survival in NOD/SCID mice.

Abstract
Heme oxygenase (HO)-1 is a stress protein that has been implicated in defense mechanisms against agents that may induce oxidative injury, such as endotoxins, heme, and cytokines. Overexpression of HO-1 in cells might, therefore, protect against oxidative stress produced by certain agents, specifically heme, by catalyzing its degradation to bilirubin, which by itself has antioxidant properties. We report for the first time the successful transduction of human HO-1 gene into rat lung microvessel endothelium using replication-defective retroviral vector. Cells transduced with human HO-1 gene exhibited a 2.1-fold increase in HO-1 protein level, which was associated with a 2.3-fold elevation in enzyme activity compared with that in nontransduced cells. The cGMP content in transduced endothelial cells was increased by 2.9-fold relative to that in nontransduced cells. Moreover, human HO-1 gene-transduced endothelial cells acquired substantial resistance to toxicity produced by exposure to heme and H(2)O(2) compared with that in nontransduced cells. The protective effect of enhancement of HO-1 activity against heme and H(2)O(2) was reversed by pretreatment with stannic mesoporphyrin, a competitive inhibitor of HO. These data demonstrate that the induction of HO-1 in response to injurious stimuli represents an important mechanism for moderating the severity of cell damage. Regulation of HO activity in this manner may have clinical applications.

Abstract
Adenoviral vectors have the potential to infect a large number of cell types including quiescent cells. Their use in hematopoietic cells is limited by the episomal form of their DNA, leading to transgene loss in the progeny cells. However, the use of this vector may be interesting for short-term in vitro modifications of primitive human hematopoietic cells. Therefore, we have investigated the ability of adenovirus to transduce cord blood CD34+ cells. Several promoters were tested using the lacZ reporter gene. The PGK and CMV promoters induced transgene expression in 18-25% of the cells, whereas the HTLV-I and especially the RSV promoter were almost inactive. To improve infection efficiency, adenovirus was complexed with cationic lipids. Lipofectamine, Cellfectin, and RPR120535b, but not Lipofectin, Lipofectace, or DOTAP, markedly improved transgene expression in CD34+ cells (from 19 to 35%). Lipofectamine strongly enhanced infection efficiency of the poorly infectable primitive CD34+CD38low cells (from 11 to 28%) whereas the more mature CD34+CD38+ cells were only slightly affected (from 24 to 31%). Lipofectamine tripled the infection of CFU-GMs and LTC-ICs derived from the CD34+CD38low cell fraction (from 4 to 12% and from 5 to 16%, respectively) and doubled that of BFU-Es (from 13 to 26%). We conclude that cationic lipids can markedly increase the efficiency of adenovirus-mediated gene transfer into primitive hematopoietic cells.
