    Abstract Cancer is the second leading cause of death in humans. Despite rapid developments in diagnostic methods and therapies, metastasis and resistance to administrated drugs are the main obstacles to successful treatment. Therefore, the main challenge should be the diagnosis and design of optimal therapeutic strategies for patients to increase their chances of responding positively to treatment and increase their life expectancy. In many types of cancer, a deregulation of multiple pathways has been found. This includes disturbances in cellular metabolism, cell cycle, apoptosis, angiogenesis, or epigenetic modifications. Additionally, signals received from the microenvironment may significantly contribute to cancer development. Chemical agents obtained from natural sources seem to be very attractive alternatives to synthetic compounds. They can exhibit similar anti-cancer potential, usually with reduced side effects. It was reported that natural compounds obtained from fruits and vegetables, e.g., polyphenols, flavonoids, stilbenes, carotenoids and acetogenins, might be effective against cancer cells in vitro and in vivo. Several published results indicate the activity of natural compounds on protein expression by its influence on transcription factors. They could also be involved in alterations in cellular response, cell signaling and epigenetic modifications. Such natural components could be used in our diet for anti-cancer protection. In this review, the activities of natural compounds, including anti-cancer properties, are described. The influence of natural agents on cancer cell metabolism, proliferation, signal transduction and epigenetic modifications is highlighted.

    Abstract Mitochondria play important roles as energetic centers. Mutations in mitochondrial DNA (mtDNA) were found in several diseases, including cancers. Studies on cytoplasmic hybrids (cybrids) confirm that directed mutation introduced into mtDNA could be a reason for cancer induction. Mitochondria could also be a factor linking cancer transformation and progression. The importance of mitochondria in cancer also confirms their involvement in the resistance to treatment. Resistance to treatment of cancer cells can frequently be a reason for glycolysis acceleration. It could be explained by cancer cells' high proliferation index and high energy request. The involvement of mitochondria in metabolic disturbances of several metabolic diseases, including cancers, was reported. These data confirm that cancer induction, as well as cancer progression, could have metabolic roots. The aberrant products observed in prostate cells involved in the Krebs cycle could promote cancer progression. These multiple relationships between alterations on a genetic level translated into disturbances in cellular metabolism and their potential relation with epigenetic control of gene expression make cancerogenesis more complicated and prognoses' success in studies on cancer etiology more distant in time.

    Title translation Potential application for stem cells in regenerative medicine and transplantology.
    Abstract There are some cells in human body which have an ability to self-renewal and differentiation into particular type of cell. They are classified according to the source of gain and ability to differentiate. Several studies carry on directed stem cells programming toward formation of particular type of cells and also reprogramming somatic stem cells for induced pluripotent stem cells. In the future it could bring hope in elaboration of new ways of disease curing that will give a chance for getting healthy (especially cancers). Stem cells display application in regenerative medicine. They facilitate in repair of damaged or dysfunctional tissues using cells derived from patients. In many cancer types the presence of cancer stem cells was observed. Their ability to self-renewal and unlimited proliferation might be the reason of metastasis and relapse of cancer. The knowledge on complexed signaling pathways and mechanisms of their regulation may be crucial and should lead to elaboration of effective anticancer therapies.

    Title translation Evolution of monoclonal antibodies in cancer treatment.
    Abstract Since late 90s of last century the new age of directed therapy began using mainly biological constructs produced in rodents called monoclonal antibodies. The side effects of monoclonal antibodies were a challenge for pharmaceutical companies to improve the biological properties of these biological drugs. The humanization of monoclonal constructs was an idea to improve monoclonal antibodies next generation activity cancer cell reduction in humans. Moreover for some other patients sensitive for monoclonal antibodies therapy could also potentially induce immunological differences that might imply on human health. The new idea related to monoclonal antibodies was to design a small molecule constructs of nanoantibodies with ability to enter into cells. Such small molecules could find their targets inside human cells, even in nuclei leading to differences in cancer cells expression. The existing knowledge on monoclonal antibodies as well as directed activity of nanoantibodies could improve anticancer treatment efficancy of diseases.

    Abstract Apoptosis is a genetically programmed phenomenon that aids in maintaining homeostasis in multicellular organisms. The characteristic morphological features of apoptosis are highly conservative and are dependent on the cell type and the apoptotic inducer. The nuclear events occurring during apoptosis include changes at the molecular level (i.e. DNA cleavage, modifications of nuclear polypeptides, and proteolysis of several proteins important for cell maintenance), and, consequently, alterations at the morphological level (i.e. chromatin condensation, nuclear shrinkage, DNA fragmentation and apoptotic body formation). These events are still not fully understood. It is very probable that a progressive decrease in pH could also be an essential factor for the induction of nuclease and protease activities, and an important element of the optimal conditions for their function. This review details the current state of knowledge on apoptotic nuclear events, with particular focus on the proteins involved in the execution of apoptosis in cell nuclei, and on the differences in substrate cleavage profiles for different types of cell undergoing cell death.

    Abstract Chronic lymphocytic leukemia (CLL) treatment is improving; however, some patients do not respond to therapy. Due to the high heterogeneity in disease development, there is an urgent need for personalization of therapy. In the present study, the response of leukemic mononuclear cells to anticancer drugs used for CLL treatment (cladribine + mafosfamide; CM or CM combined with rituximab; RCM) was compared with the response to new cyclin‑dependent kinase (CDK) inhibitors: BP14 and BP30. Viable apoptotic and necrotic cells were quantified by flow cytometry using propidium iodide and Yo‑Pro stains. CDK inhibitors were studied in several doses to determine the reduction of necrosis and simultaneous increase of apoptosis in leukemic cell incubations with anticancer agents. The distinct cell response to applied doses/anticancer agents was observed. Results obtained in the current manuscript confirmed that modulation of doses is important. This was particularly indicated in results obtained at 24 h of cells incubation with anticancer agent. While an important time for analysis of anticancer response efficacy (monitoring of apoptosis induction potential) seems to be 48 h of cells exposition to anticancer agents. High variability in response to the drugs revealed that both the nature and the dose of the anticancer agents could be important in the final effect of the therapy. The present findings support the thesis that personalized medicine, before drug administration in the clinic, could be important to avoid the application of ineffective therapy.

    Abstract Chronic lymphocytic leukemia (CLL) is the most frequent type of hematological cancer in the Western World. An accumulation of leukemic cells in peripheral blood of patients is a result of apoptosis disturbances as well as an increase in germinal centers CLL cell proliferation. The differences between CLL patients in the course and response to therapy reflects personal variability between patients in their genetic material. It was documented that many sufferers from CLL are over 60 years old, and because of many countries' population obsolescence this type of leukemia could become more frequent in the future. CLL remains incurable, and the therapy regimens available at present could induce even complete remissions, but finally a relapse of the disease. The etiology of this disease is still not known, but our understanding of the processes running in CLL cells has significantly increased. A number of new agents with potential of CLL cell elimination by apoptosis or autophagy were characterized. Some of them reflect potential in cell sensitization to standard therapy. The major challenge for the future is to develop targeted anti-cancer therapy and design the optimal personalized manner of CLL treatment. A special interest is focused on anti-cancer agents - natural substances of plant origin. This paper reviews chosen new anti-leukemic agents belonging to different drug-classes (new monoclonal antibodies or apoptosis-, BCR signaling- and cell cycle-related inhibitors, substances of plant origin) which are under intense investigation in preclinical studies and early clinical trials.

    Abstract There is individual variation in the course of disease development and response to therapy of patients with chronic lymphocytic leukemia (CLL). Novel treatment options for CLL include a new generation of purine analogs, antibodies and inhibitors of specific cell signaling pathways, which typically induce apoptosis or necrosis. A prospective analysis of patient blood samples revealed that a combination of four tests allowed the most appropriate and effective type of treatment to be selected prior to drug administration, and for the analysis of leukemic cell sensitivity to anticancer drug(s) during disease development. The comparative analysis of blood from the stable and progressive form of CLL in an individual patient revealed diversity in the response to anticancer agents. CLL peripheral blood mononuclear cells were incubated with cladribine + mafosfamide (CM), fludarabine + mafosfamide, CM + rituximab, rituximab alone (Rit) or kinetin riboside (RK). A combination of cell viability, differential scanning calorimetry (DSC) profiles of nuclear preparations and poly(ADP-ribose) polymerase 1 (PARP-1) protein expression analysis of the leukemic cells was performed to evaluate the anticancer effects of the tested agents during CLL development. The results of the present study indicate that such studies are effective in determining the most appropriate anticancer drug and could monitor disease progression on an individual level. In addition, the results of the current study suggest that CLL progression leads to diversification of the cellular drug response. The most efficient apoptosis inducer for the patient was purine analog RK when the disease was stable, while the CM combination was the most effective agent for the progressive form of disease.

    Abstract To improve the efficacy of therapeutic options in chronic lymphocytic leukemia (CLL) an in vitro system to determine the response of mononuclear blood cells from blood of patients was elaborated. The study combines four approaches, i.e., cell viability, apoptosis rate, differential scanning calorimetry (DSC), and immunoblotting to develop personalized therapy protocols based on the cell sensitivity to drug exposure of individual CLL patients. The complementary analyses were performed on 28 peripheral blood samples from previously untreated CLL patients before therapy. The induction and progress of apoptosis in CLL cells exposed in vitro to purine analogs combined with mafosfamide, i.e., cladribine + mafosfamide (CM) and fludarabine + mafosfamide (FM) were assessed using the above approaches. The changes in thermal profiles (decrease/loss of transition at 95±5˚C) coincided with an accumulation of apoptotic cells, a decrease in the number of viable cells, and differences in the expression of the apoptosis‑related protein PARP‑1. No significant changes were observed in the thermal profiles of nuclei isolated from CLL cells resistant to the treatment. The complementary assays revealed a strong relationship between both the in vitro sensitivity of leukemia cells to drugs and the clinical response of the patients, determined usually after the sixth course of treatment (after ~6 months of therapy). As a summary of studies followed by complementary tests, our findings demonstrate the value of in vitro exposure of CLL cell samples to drugs intended to treat CLL patients, before their administration in order to recommend the most suitable and effective therapy for individual patients.
