Opis:
This short review attempts to demonstrate the usefulness of antiangiogenic gene therapy in achieving inhibition of growth in experimentally-induced metastases. Certain normal tissues (for example skeletal muscle) may be used in vivo, after genetic modification, as a "bioreactor", able to produce and secrete into the bloodstream proteins known to exert antiangiogenic effects. By inhibiting neoangiogenesis these proteins would thus prevent the development of metastases. The review discusses also the perspectives of antimetastatic therapy based on certain types of allogenic cells (for example myoblasts and fibroblasts) that had been genetically modified and then microencapsulated. The strategy of encapsulation is aimed at protecting the modified cells secreting antiangiogenic factors from being eliminated by the immune system. Secretion of antiangiogenic proteins by these microencapsulated cells can be controlled with inducible promoters. Antiangiogenic genes remaining under the transcriptional control of such promoters may be switched on and off using antibiotics, such as tetracycline derivatives, or steroid hormones.

Opis:
In the majority of potential applications gene therapy will require an effective transfer of a transgene in vivo resulting in high-level and long-term transgene expression, all in the absence of significant toxicity or inflammatory responses. The most efficient vehicles for delivery of foreign genes to the target tissues are modified adenoviruses. Adenoviral vectors of the first generation, despite the high infection efficacy, have an essential drawback: they induce strong immune response, which leads to short term expression of the transgene, and limits their usefulness in clinical trials. In contrast, helper-dependent adenoviral vectors (HdAd) lacking all viral coding sequences display only minimal immunogenicity and negligible side-effects, allowing for long-term transgene expression. Thus, HdAd vehicles have become the carrier of choice for adenoviral vector-mediated experimental gene therapy, effectively used in animal models for delivery of transgenes into the liver, skeletal muscle, myocardium or brain. Strong and long-lasting expression of therapeutic genes has allowed for successful treatment of dyslipidemias, muscular dystrophy, obesity, hemophilia, and diabetes. Additionally, the large cloning capacity of HdAd, up to 37 kb, facilitates the use of physiologically regulated, endogenous promoters, instead of artificial viral promoter sequences. This enables also generation of the single vectors expressing multiple genes, which can be potentially useful for treatment of polygenic diseases. In this review we characterize the basic features of HdAd vectors and describe some of their experimental and potential clinical applications.

Opis:
Gene therapy and genetic vaccines promise to revolutionize the treatment of inherited and acquired diseases. Since viral vectors are generally associated with numerous disadvantages when applied to humans, the administration of naked DNA, or DNA packed into lipo- or polyplexes emerge as viable alternatives. To satisfy the increasing demand for pharmaceutical grade plasmids we developed a novel economic downstream process which overcomes the bottlenecks of common lab-scale techniques and meets all regulatory requirements. After cell lysis by an in-house developed gentle, automated continuous system the sequence of hydrophobic interaction, anion exchange and size exclusion chromatography guarantees the separation of impurities as well as undesired plasmid isoforms. After the consecutive chromatography steps, adjustment of concentration and final filtration are carried out. The final process was proven to be generally applicable and can be used from early clinical phases to market-supply. It is scaleable and free of animal-derived substances, detergents (except lysis) and organic solvents. The process delivers high-purity plasmid DNA of homogeneities up to 98% supercoiled form at a high yield in any desired final buffer.

Opis:
Alterations in the expression of growth factors and their receptors are associated with the growth and development of human tumors. One such growth factor is IGF-I (insulin-like growth factor I ), a 70-amino-acid polypeptide expressed in many tissues, including brain. IGF-I is also expressed at high levels in some nervous system-derived tumors, especially in glioblastoma. When using IGF-I as a diagnostic marker, 17 different tumors are considered as expressing the IGF-I gene. Malignant glioma, the most common human brain cancer, is usually fatal. Average survival is less than one year. Our strategy of gene therapy for the treatment of gliomas and other solid tumors is based on: 1) diagnostic using IGF-I gene expression as a differential marker, and 2) application of "triple-helix anti-IGF-I " therapy. In the latter approach, tumor cells are transfected with a vector, which encodes an oligoribonucleotide - an RNA strand containing oligopurine sequence which might be capable of forming a triple helix with an oligopurine and/or oligopyrimidine sequence of the promotor of IGF-I gene (RNA-IGF-I DNA triple helix). Human tumor cells transfected in vitro become down-regulated in the production of IGF-I and present immunogenic (MHC-I and B7 expression) and apoptotic characteristics. Similar results were obtained when IGF-I antisense strategy was applied. In both strategies the transfected cells reimplanted in vivo lose tumorigenicity and elicit tumor specific immunity which leads to elimination of established tumors.

Opis:
According to statistics, ovarian cancer is the fourth cause of death due to gynecologic cancer. It results from late diagnosis of the disease, caused by the lack of characteristic symptoms, as well as from unsatisfactory treatment methods due to e.g. cell resistance to chemotherapy. The search for new therapies is still in progress. It is believed that preparations whose activity is based on RNA interference, i.e. gene silencing with the use of siRNA, are a promising group of new antineoplastic medications. Fire et al. were awarded the Nobel Prize for discovering this phenomenon. The phenomenon of siRNA interference in healthy cells is a natural protective mechanism. Genes are silenced in the cytoplasm with the use of the Dicer enzyme. siRNA gene preparations are delivered into cells with the use of viral methods such as AAV or adenoviruses, as well as non-viral methods e.g. with the use of liposomes. Clinical trials concerning siRNA preparations are now in the first phase. They are conducted on two gene preparations: CALAA-01 and siRNA nanomolecule directed against PLK1. In this paper attention was drawn to the therapeutic meaning of siRNA sequences in relation to the following genes: MDR1, VEGF, MMP, CD44, HER2, SHH, STAT. Both experimental and clinical studies give hope for the use of the described mechanisms in fight with ovarian cancer in the future.
Rak jajnika według statystyk zajmuje czwarte miejsce wśród zgonów z powodu nowotworów ginekologicznych. Wynika to zarówno z późnego rozpoznania choroby, spowodowanego brakiem charakterystycznych objawów, jak i stale niezadowalających efektów leczenia, m.in. ze względu na oporność komórek na chemioterapię. Poszukiwanie nowych metod terapii jest więc nadal aktualne. Uważa się, że obiecującą grupą potencjalnych leków przeciwnowotworowych mogą być preparaty, których aktywność opiera się na zjawisku interferencji RNA, czyli wyciszaniu genów za pomocą siRNA. Za odkrycie tego zjawiska Fire i wsp. zostali uhonorowani Nagrodą Nobla. Zjawisko interferencji siRNA w prawidłowych komórkach jest naturalnym mechanizmem obronnym. Do wyciszenia genów dochodzi w cytoplazmie przy udziale enzymu Dicer. Preparaty genowe siRNA wprowadza się do komórek, wykorzystując metody wirusowe, takie jak AAV czy adenowirusy, a także za pomocą metod niewirusowych, np. z zastosowaniem liposomów. Badania kliniczne preparatów genowych siRNA znajdują się obecnie w pierwszej fazie. Prowadzone są na dwóch preparatach genowych CALAA-01 oraz na nanocząsteczce siRNA skierowanej przeciw PLK1. W niniejszej pracy skupiono uwagę na terapeutycznym znaczeniu sekwencji siRNA w stosunku do genów: MDR1, VEGF, MMP, CD44, HER2, SHH, STAT. Zarówno badania eksperymentalne, jak i kliniczne niosą nadzieję na wykorzystanie w przyszłości omawianego mechanizmu do walki z rakiem jajnika.

Opis:
Angiogenesis, i.e. formation of new blood vessels out of pre-existing capillaries, is essential to the development of tumour vasculature. The discovery of specific antiangiogenic inhibitors has important therapeutic implications for the development of novel cancer treatments. Vasostatin, the N-terminal domain of calreticulin, is a potent endogenous inhibitor of angiogenesis and tumour growth. In our study, using B16(F10) murine melanoma model and electroporation we attempted intramuscular transfer of human vasostatin gene. The gene therapy was combined with antiangiogenic drug dosing schedule of a known chemotherapeutic (cyclophosphamide). The combination of vasostatin gene therapy and cyclophosphamide administration improved therapeutic effects in melanoma tumours. We observed both significant inhibition of tumour growth and extended survival of treated mice. To our knowledge, this is one of the first reports showing antitumour efficacy of electroporation-mediated vasostatin gene therapy combined with antiangiogenic chemotherapy.

Opis:
Manipulation of angiogenesis in vivo is an example of successful gene therapy strategies. Overexpression of angiogenic genes like VEGF, FGF or PDGF causes new vessel formation and improves the clinical state of patients. Gene therapy is a very promising procedure but requires large amounts of pharmaceutical-grade plasmid DNA. In this regard we have constructed a bicistronic plasmid DNA vector encoding two proangiogenic factors, VEGF165 and FGF-2. The construct (pVIF) contains the internal ribosome entry site (IRES) of the encephalomyocarditis virus (ECMV) which permits both genes to be translated from a single bicistronic mRNA. The IRES sequence allows for a high efficiency of gene expression in vivo. The pVIF vector was characterized in vitro and in vivo. In vivo angiogenesis studies showed that the bicistronic vector encoding two proangiogenic factors induces the formation of new vessels significantly more than pVEGF165 or pFGF-2 alone. In our opinion the combined proangiogenic approach with VEGF165 and FGF-2 is more powerful and efficient than single gene therapy. We also postulate that IRES sequence can serve as a useful device improving efficiency of gene therapy.

Opis:
Terapia genowa jest obecnie bardzo dynamicznie rozwijającą się techniką biomedyczną, która może znaleźć zastosowanie w medycynie w leczeniu chorób przewlekłych i dziedzicznych. Badania skupiają się na opracowywaniu nowych strategii dotyczących procesów kondensacji i ochrony materiału genetycznego (DNA) wprowadzanego do komórki docelowej. Struktura i stopień upakowania dostarczanego DNA wpływają na kluczowe właściwości fizykochemiczne, determinujące czy wprowadzony wektor rekombinowany ulegnie ekspresji, czy też degradacji. Związki chemiczne, zwane czynnikami kondensującymi, to substancje powodujące zwinięcie DNA, a stopień kondensacji materiału genetycznego zależy bezpośrednio od rodzaju i stężenia użytego czynnika kondensującego. Do cząsteczek wykazujących właściwości kondensujące należą poliaminy, w opisywanym eksperymencie zastosowano poliaminę – spermidynę. Przeprowadzone badania miały na celu charakterystykę nanostrukturalną materiału genetycznego pod wpływem działania czynnika kondensującego. W wyniku analizy wykonanej za pomocą mikroskopii sił atomowych (AFM) wykazano, że plazmid DNA ulega kondensacji pod wpływem spermidyny, formując struktury rozetowe.
Gene therapy is a new promising method that may find many applications in modern biomedicine. Especially, it may be a powerful tool in chronic and hereditary diseases treatment. Current studies focus on development of novel strategies concerning genetic material (DNA) condensation and protection, whilst it is introduced into the cellular nucleus. Once the DNA enters the cell, it’s either passed on and expressed in the nucleus or degraded by intracellular nucleases. The structure and the degree of compaction influence physicochemical properties that determine what will happen to delivered genetic material. DNA coiling can be caused by chemical compounds called compaction agents, such as polyamines like spermidine used in this study. The aim of this research was to examine the nanostructural characteristics of genetic material exposed to compaction agent. The measurements and analysis performed by atomic force microscopy (AFM) indicate that DNA plasmid undergoes condensation and forms rosette-like structures once subjected to spermidine.

Opis:
X-linked adrenoleukodystrophy is a genetic disease correlated with mutation of ATP-binding cassette, which results in errors of peroxisomal beta oxidation and accumulation of impaired very long chain fatty acids. This leads to degeneration of adrenal glands, spinal cord and myelin sheaths. Despite nearly 100 years of ALD history, the treatment is limited to few therapeutic options, mainly Lorenzo’s Oil and Hematopoetic stem cell transplant. Available therapy can only slow the progression of the disease in early stages. The aim of our study was to present the newest therapeutic options in X-ALD. Substantial articles on new treatment of X-ALD from period 2007-2018 in the Asian, European and American regions have been analyzed. Among 219 articles in PubMed Medline database related to therapy and treatment of X-ALD, 13 articles were selected for analysis, reviewed and divided into two main groups: cause-related treatment (11 articles) and symptoms-related treatment (2 articles). Within cause-related treatment, the usage of known medications such as eg. pioglitazone, natural phenols - resveratrol, gene therapy with adenoassociated virus serotype 9 or combined therapies (Hematopoetic Stem Cell Gene Therapy) have been reviewed. Symptoms related treatment attempted to reduce spasticity and secondary dystonia in X-ALD patients. Reviewed research presents progress in development of treatment options for X-ALD, however still in primary in vitro and animal tested stages. Secondary neurological symptoms medication is awaiting for better solutions for ALD patients, in order to improve their Quality of Life and allow symptomless course for a longer time.

We investigated suppression of murine B16(F10) melanoma tumor growth following a therapy which involved concomitant administration of cyclophosphamide and plasmid DNA bearing interleukin-12 gene. Since both therapeutic factors display antiangiogenic capabilities, we assumed that their use in blocking the formation of new blood vessels would result in augmented inhibition of tumor growth. This combined therapy regimen indeed resulted in a considerable suppression of tumor growth. We observed a statistically significant extension of treated animals' lifespan. Interestingly, the therapeutic effect was also obtained using a plasmid without an interleukin gene insert. This observation suggests that plasmid DNA, which has been widely applied for treating neoplastic tumors, contains element(s) that elicit immune response in mice.

A tumour therapy is proposed based on attenuated Salmonella typhimurium VNP20047 expressing the Escherichia coli cytosine deaminase gene. VNP20047 was administered intravenously to B16(F10) melanoma-bearing C57BL/6 mice. VNP20047 proliferated within tumours and livers regardless of the initial inoculum dose. After 10 days the number of bacteria increased in livers up to 4.2 × 106 cfu/g and decreased in tumours down to 5.9 × 106 cfu/g. VNP20047 at 1 × 105 cfu/mouse, when combined with 5-fluorocytosine, inhibited tumour growth by 85% without prolonging animal survival. Histology studies revealed severe lesions in tumours and livers. These data suggest that S. typhimurium VNP20047 induced inflammatory responses, even though the strain was attenuated.

Transfer of naked DNA carrying the IL-12 gene into growing Renca tumors causes a distinct therapeutic effect that depends on the time span between inoculation of mice with cancer cells and the beginning of the therapy. Therapy started on day 3 resulted in total cure (100%) of mice.

When angiostatin-mediated antiangiogenic therapy was used in combination with intratumor delivery of the IL-12 gene (a strategy much safer than IL-12 protein administration), this produced a synergistic therapeutic effect.

The ability of various cytokines to hamper tumor growth or to induce anti-tumor immune response has resulted in their study as antitumor agents in gene therapy approaches. In this review we will concentrate on the costimulation of antitumor immune responses using modification of various cell types by cytokine genes. Several strategies have emerged such as (i) modification of tumor cells with cytokine genes ex vivo (whole tumor cell vaccines), (ii) ex vivo modification of other cell types for cytokine gene delivery, (iii) delivery of cytokine genes into tumor microenvironment in vivo, (iv) modification of dendritic cells with cytokine genes ex vivo. Originally single cytokine genes were used. Subsequently, multiple cytokine genes were applied simultaneously, or in combination with other factors such as chemokines, membrane bound co-stimulatory molecules, or tumor associated antigens. In this review we discuss these strategies and their use in cancer treatment as well as the promises and limitations of cytokine based cancer gene therapy. Clinical trials, including our own experience, employing the above strategies are discussed.
