Abstract
Introduction and importance Pyoderma gangrenosum is an unusual inflammatory pathology, with neutrophilic dermatosis, of unknown etiology. It is associated with diseases such as bowel disease. Generally, it is treated with anti-inflammatory drugs, corticosteroids, immunosuppressants, and antibodies against tumor necrosis factor, but relapse and adverse effects are persistent. Pentoxifylline is a drug with immunoregulatory and anti-inflammatory properties. Case presentation A 47-year-old male with a diagnosis of ulcerative colitis initially managed favorably for 7 years with mesalazine. At 3 years of treatment, he presented a sudden ulcer that affected skin and subcutaneous tissue (13×10 cm) in the lower right limb. During the last 2 years, he was treated with mesalazine and infliximab with partial results and permanent relapses. Therefore, pentoxifylline was added to his treatment. Clinical discussion The justification for the addition of pentoxifylline is mainly its action as an inhibitor of Nuclear Factor-kappa Beta (NF-κB) transcription, which stimulates the expression of proinflammatory interleukin genes such as IL-1, IL-6, IL- 8, and TNF-α and showing immunoregulatory and antioxidant activities. Conclusion With pentoxifylline, this lesion healed at 6 weeks without relapses after 2 years.

Abstract
Cervical cancer (CC) is one of the most common and deadly types of female cancer worldwide. Late diagnosis in CC increases the risk of tumor cells spreading to distant organs (metastasis). The epithelial-mesenchymal transition (EMT) is a fundamental process of cancer metastasis. Inflammation can lead to tumor progression, EMT induction, and metastasis. The inflammatory microenvironment is a potent inducer of EMT; inflammatory cytokines such as Tumor Necrosis Factor-alpha (TNF-α) and Transforming growth factor-beta (TGF-β1) activate transcriptional factors such as STAT3, Snail, Smad, and the Nuclear Factor kappa light-chain-enhancer of activated beta cells (NF-κΒ), which drive EMT. Anti-inflammatory compounds may be an option in the disruption of EMT. PenToXifylline (PTX) possesses potent anti-inflammatory effects by inhibiting NF-κB activity. In addition, PTX exerts an anti-fibrotic effect by decreasing Smad2/3/4. We hypothesize that PTX could exert anti-EMT effects. CaSki human cervical tumor cells were exposed to TNF-α 10 ng/mL and TGF-β1 alone or in combination for 5 days. Our results revealed that TNF-α and TGF-β1 induced N-cadherin and Vimentin, confirming the induction of EMT. Furthermore, the combination of cytokines synergized the expression of mesenchymal proteins, enhanced IκBα and p65 phosphorylation, and upregulated Serpin family E member 1 (SERPINE1) mRNA. PTX pretreatment prior to the addition of TNF-α and TGF-β1 significantly reduced N-cadherin and Vimentin levels. To our knowledge, this is the first time that this effect of PTX has been reported. Additionally, PTX reduced the phosphorylation of IκB-α and p65 and significantly decreased SERPINE1 expression, cell proliferation, migration, and invasion. In conclusion, PTX may counteract EMT in cervical cancer cells by decreasing the NF-κB and SERPINE1.

Abstract
Acute lymphoblastic leukemia (ALL) in children or adults is characterized by structural and numeric aberrations in chromosomes; these anomalies strongly correlate with prognosis and clinical outcome. Therefore, this work aimed to identify the genes present in chromosomal gain regions found more frequently in patients with acute lymphoblastic leukemia (ALL) and ALL-derived cell lines using comparative genomic hybridization (CGH). In addition, validation of the genes found in these regions was performed utilizing RNAseq from JURKAT, CEM, and SUP-B15 cell lines, as well as expression microarrays derived from a MILE study. Chromosomes with common gain zones that were maintained in six or more samples were 14, 17, and 22, in which a total of 22 genes were identified. From them, NT5C3B, CNP, ACLY, and GNB1L maintained overexpression at the mRNA level in the cell lines and in patients with ALL. It is noteworthy that SALL2 showed very high expression in T-ALL, while JUP was highly expressed in B-ALL lineages. Interestingly, the latter correlated with worse survival in patients. This provided evidence that the measurement of these genes has high potential for clinical utility; however, their expressions should first be evaluated with a sensitive test in a more significant number of patients.

Abstract
Prostate cancer (PCa) is a key public health problem worldwide; at diagnosis, a high percentage of patients exhibit tumor cell invasion of adjacent tissue. STAT‑3, IL‑6 receptor (R) and IL‑6 serum levels are associated with enhanced PCa migratory, invasive, clonogenic and metastatic ability. Inhibiting the STAT‑3 pathway at different levels (cytokines, receptors, and kinases) exhibits relative success in cancer. The present study investigated the effect of Stattic (Stt) + Tocilizumab (Tcz) on proliferative, clonogenic, migratory and invasive ability of human metastatic PCa (assessed by colony formation, wound healing and migration assay). RWPE‑1 (epithelial prostate immortalized cells), 22Rv1 (Tumor cells), LNCaP (Metastatic cells) and DU‑145 (metastatic, castration‑resistant prostate cells) cells were used in vitro to evaluate levels of cytokines, chemokines, growth factors (Cytometric Bead Array), STAT‑3, phosphorylated STAT‑3 (In‑Cell Western), IL‑6R, vimentin and epithelial (E‑) cadherin (Western Blot). The effect of inhibition of STAT‑3 (expressed constitutively in DU‑145 cells) with Stt and/or Tcz on expression levels of vimentin, VEGF, and E‑cadherin, as well as proliferative, clonogenic, migratory and invasive capacity of metastatic PCa cells was assessed. The expression levels of IL‑6, C‑X‑C chemokine ligand 8, VEGF and vimentin, as well as proliferation and migration, were increased in metastatic PCa cells. Treatment with Stt or Tcz decreased vimentin and VEGF and increased E‑cadherin expression levels and inhibited proliferative, clonogenic, migratory and invasive capacity of DU‑145 cells; addition of IL‑6 decreased this inhibitory effect. However, Stt + Tcz maintained inhibition even in the present of high concentrations of IL‑6. Stt + Tcz decreased expression of vimentin and VEGF and inhibited the proliferative, clonogenic, migratory and invasive capacity of metastatic PCa cells. To the best of our knowledge, the present study is the first to combine Stt, a STAT‑3 inhibitor, with Tcz, an antibody against IL‑6R, to target tumor cells.

Abstract
Although acute stress generally exerts positive effects on the immune system, chronic stress typically causes immunosuppression via the hypothalamic-pituitary-adrenal (HPA) axis. In this study, the effects of capsaicin (1.28 mg/kg intraperitoneally [i.p.] for 7 days) on immune parameters were evaluated under conditions of chronic stress. Capsaicin treatment significantly increased the immune response as evaluated by the delayed-type hypersensitivity (DTH) reaction to dinitrofluorobenzene (DNFB) and splenocyte proliferation assays- It also is able to rescue the splenocytes of the apoptosis induced by stress. The capsaicin treatment increased the production of Th1 cytokines and decreased the production of Th2 cytokines and TGF-β1 in the plasma and culture supernatants of immunosuppressed mice, which is associated with the modulation of Th2 induced by stress cells. Moreover, the production of corticosterone significantly decreased in capsaicin-treated animals as compared to control groups. The capsaicin treatment further attenuated the immunosuppression induced by the corticosterone treatment (40 mg/kg i.p. for 7 days), albeit less potently, as exhibited in the DTH response. Intriguingly, the capsaicin treatment decreased the induction of IL-10, IL-4, and TGF-β1 through high doses of corticosterone, indicating direct cellular immunomodulation. These results show, that capsaicin is able to modulate chronic stress-induced immunosuppression, mediating corticosterone released inhibition, but also, that capsaicin significantly modulates the pharmacological action of corticosterone in vivo.

Abstract
BACKGROUND Prostate cancer is one of the most frequently diagnosed types of cancers worldwide. In its initial period, the tumor is hormone-sensitive, but in advanced states, it evolves into a metastatic castration-resistant tumor. In this state, chemotherapy with taxanes such as Docetaxel (DTX) comprises the first line of treatment. However, the response is poor due to chemoresistance and toxicity. On the other hand, Pentoxifylline (PTX) is an unspecific inhibitor of phosphodiesterases; experimental, and clinically it has been described as sensitizing tumor cells to chemotherapy, increasing apoptosis and decreasing senescence. We study whether the PTX sensitizes prostate cancer cells to DTX for greater effectiveness. METHODS PC3 human prostate cancer cells were treated in vitro at different doses and times with PTX, DTX, or their combination. Viability was determined by the WST-1 assay by spectrophotometry, cell cycle progression, apoptosis, generic caspase activation and senescence by flow cytometry, DNA fragmentation and caspases-3, -8, and -9 activity by ELISA. RESULTS We found that PTX in PC3 human prostate cancer cells induces significant apoptosis per se and increases that generated by DTX, while at the same time it reduces the senescence caused by the chemotherapy and increases caspases-3,-8, and -9 activity in PTX + DTX-treated cells. Both treatments blocked the PC3 cell in the G1 phase. CONCLUSIONS Our results show that PTX sensitizes prostate tumor cells to apoptosis induced by DTX. Taken together, the results support the concept of chemotherapy with rational molecular bases.

Abstract
Background Cervical cancer continues to be a major public health problem worldwide, and Cisplatin is used as first-line chemotherapy for this cancer; however, malignant cells exposed to CISplatin (CIS) become insensitive to the effects of this drug. PenToXifylline (PTX) is a xanthine that sensitizes several types of tumor cells to apoptosis induced by antitumor drugs, such as Adriamycin, Carboplatin, and CIS. The effects of PTX on tumor cells have been related to the disruption of the NF-κB pathway, thus preventing the activation of cell survival mechanisms such as the expression of anti-apoptotic genes, the secretion of proinflammatory interleukins, and growth factors. Objective In this work, we studied the antitumor proprieties of PTX in human SiHa cervical carcinoma cells resistant to CIS. Materials and Methods SiHa and HeLa cervical cancer cells and their CIS-resistant derived cell lines (SiHaCIS-R and HeLaCIS-R, respectively) were used as in-vitro models. We studied the effects of PTX alone or in combination with CIS on cell viability, apoptosis, caspase-3, caspase-8, and caspase-9 activity, cleaved PARP-1, anti-apoptotic protein (Bcl-2 and Bcl-xL) levels, p65 phosphorylation, cadmium chloride (CdCl2) sensitivity, Platinum (Pt) accumulation, and glutathione (GSH) levels, as well as on the gene expression of GSH and drug transporters (influx and efflux). Results PTX sensitized SiHaCIS-R cells to the effects of CIS by inducing apoptosis, caspase activation, and PARP-1 cleavage. PTX treatment also decreased p65 phosphorylation, increased Pt levels, depleted GSH, and downregulated the expression of the ATP7A, ATP7B, GSR, and MGST1 genes. Conclusion PTX reverses the acquired phenotype of CIS resistance close to the sensitivity of parental SiHa cells.

Abstract
Breast cancer is the most frequent cancer in women worldwide, and drug resistance is common in all breast cancer types. The combination of natural products with chemotherapies has attracted attention, as it was found that natural compounds enhance the effects of standard cancer chemotherapeutic drugs and protect from side effects. Into the different natural products, garlic has been recognized for its antitumor properties. It is suggested that its anticancer effects are associated with its organo-sulfur compounds, especially alliin and allicin. Here, we evaluated the effects of both molecules on cell death, senescence, and their senolytic potential in luminal A and triple-negative breast cancer cells. MCF-7 (luminal A) and HCC-70 (triple-negative) cells were cultured and treated with different concentrations of alliin or allicin. Then, cell viability was determined using the WST-1 reagent. Apoptosis and caspase activity were evaluated by flow cytometry; ΔΨm was assessed using a JC-10 fluorometric assay kit. Apoptosis-related genes were evaluated by RT-PCR. Proliferation was measured using bromodeoxyuridine incorporation. We also evaluated clonogenicity, senescence (β-Galactosidase Staining), and the senolytic effect of the compounds. Our results showed that allicin has antiproliferative, anticlonogenic, and senolytic effects. In addition, allicin decreased cell viability and induced apoptosis by loss of ΔΨm, caspase-3, caspase-8, and caspase-9 activation, upregulation of NOXA, P21, and BAK, as well as downregulation of BCL-XL expression. Contrary to allicin, alliin promoted clonogenicity, induced senescence, and did not exhibit pro-apoptotic effects in breast cancer cells.

Abstract
Macrophages are presents in the tumor microenvironment and acquire
different phenotypic and functional characteristics in response to
microenvironmental signals. Macrophages can be differentiated into two
phenotypes: M1 or pro-inflammatory (classically activated), and M2 or
anti-inflammatory macrophage (alternatively activated). In response to
the microenvironment, macrophages activate transcription factors as
STAT1 and NF-κB-p65 for M1 macrophages or STAT3 and STAT6 for M2
macrophages; activation impacts on the profile of cytokine, chemokines
and growth factors secreted by macrophages. We evaluated the effect of
the supernatant of cervical-derived carcinoma cell lines HeLa, SiHa,
and C-33A on the phosphorylation of transcriptional factors STAT1,
NF-κB-p65, and STAT6, and their impact in the profile of secretion of
cytokines and growth factors by macrophages derived from the U937 cell
line. The results show that in macrophages, these supernatants induce
a decrease in the phosphorylation of NF-κB-p65 and STAT1 in
U937-macrophages accompanied by an increase in the secretion of IL-10,
IL-6, MCP-1, and IL-8, as well as GM-CSF, G-CSF, PDGF-AA, PDGF-BB, and
VEGF. Our results suggest that HeLa, SiHa, and C-33A cell lines
down-regulate the activation of transcription factors characteristic
of M1 macrophages (STAT1, NF-κB-p65) and induce the secretion of
factors that favor tumor growth.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the sixth most frequent tumor worldwide and it is responsible for approximately 750 000 deaths each year. It is the third leading cause of cancer death in Mexico. Despite the existing therapeutic regimens, HCC has a poor prognosis with a life expectancy of approximately one month in advanced cases. The use of celecoxib and pentoxifylline has recently been reported in tumor patients with promising results due to its anti-inflammatory, antiangiogenic, antifibrotic and proapoptotic effects. Nonetheless, the combination of both drugs for the treatment of HCC has never been employed. CLINICAL CASE 58-year-old male patient, who arrived to the examination room for presenting nausea, jaundice, asthenia, adynamia and encephalopathy grade I-II. The patient had a history of alcoholism for 47 years and diagnosis of cirrhosis in Child C stage. An image with focal lesion in the right lobe of 8 x 8 cm, which was highly vascularized, suggested HCC by means of imaging studies (ultrasound, computed axial tomography [CAT] and magnetic resonance imaging). Management began in January, 2015, and continues until today with 400 mg of pentoxifylline every 12 hours, 200 mg of celecoxib every 12 hours and vitamin supplements. CONCLUSION After one month, patient showed a surprising response, reduction in tumor size almost in its entirety, improvement of clinical condition, and turned into Child A stage. Eight months after treatment it was observed by CAT that the tumor had practically disappeared. Patient has survived for more than two years. These results are encouraging; however, it is necessary to conduct multicenter studies that prove the efficacy of the treatment.

Abstract
The transcription factor grainyhead-like 2 (GRHL2) is evolutionarily conserved in many different species, and is involved in morphogenesis, epithelial differentiation, and the control of the epithelial-mesenchymal transition. It has also recently been implicated in carcinogenesis, but its role in this remains controversial. Expression of GRHL2 has not previously been reported in cervical cancer, so the present study aimed to characterize GRHL2 expression in cervical cancer-derived cell lines (CCCLs) and cervical tissues with different grades of lesions. Microarray analysis found that the expression of 58 genes was down-regulated in CCCLs compared to HaCaT cells (non-tumorigenic human epithelial cell line). The expression of eight of these genes was validated by quantitative real-time PCR (qPCR), and GRHL2 was found to be the most down-regulated. Western blot assays corroborated that GRHL2 protein levels were strongly down-regulated in CCCLs. Cervical cells from women without cervical lesions were shown to express GRHL2, while immunohistochemistry found that positivity to GRHL2 decreased in cervical cancer tissues. In conclusion, a loss or strong reduction in GRHL2 expression appears to be a characteristic of cervical cancer, suggesting that GRHL2 down-regulation is a necessary step during cervical carcinogenesis. However, further studies are needed to delineate the role of GRHL2 in cervical cancer and during malignant progression.

Abstract
Background Natural killer (NK) cells eliminate virus-infected and tumor cells through the release of perforins and granzymes; they also produce Interferon gamma (IFN-γ) and Tumor necrosis factor alpha (TNF-α), which induce apoptosis in target cells. Many tumors express Heme oxygenase 1 (HO-1), and this expression has been associated with avoiding immunosuppression and apoptosis. In this work, HO-1+ Cervical cancer cell (CCC) lines were pre-treated with HO-1 inhibitor and we assessed whether this inhibition enhanced the sensitivity of CCC to NK cell activity. Methods We assessed the expression of HO-1 in HeLa, SiHa, and C-33A CCC by Flow cytometry (FC). CCC were pre-treated with SnPP or ZnPP HO-1 inhibitors. After that, NK-92 cells were co-cultured with HeLa, SiHa, and C-33A CCC pre-treated or not with HO-1 inhibitors, and the expression of IFN-γ, TNF-α, CD107a, Granzyme B, NKp44, NKp46, NKp30, and NKG2D was evaluated by FC. Results CCC lines HeLa, SiHa, and C-33A expressed HO-1. Inhibition of HO-1 in these cells increased the expression of IFN-γ and TNF-α in CD107a + NK-92 cells. We observed a reduction in the expression of NKG2D, NKp46, and NKp30 in NK cells co-cultured with HeLa and SiHa cells, and when HeLa and SiHa cells were pre-treated with the HO-1 inhibitors, the expression of NKG2D and NKp30 in NK cells was restored. We observed a similar effect in NK cells co-cultured with C-33A cells in NKp30 expression. Conclusion Inhibition of HO-1 in CCC induces an increase in IFN-γ and TNF-α production in CD107a + NK-92 cells and restores NKG2D, NKp46 and NKp30 downmodulation in NK cells.

Abstract
Background The resistance of cancerous cells to chemotherapy remains the main limitation for cancer treatment at present. Doxorubicin (DOX) is a potent antitumor drug that activates the ubiquitin-proteasome system, but unfortunately it also activates the Nuclear factor kappa B (NF-кB) pathway leading to the promotion of tumor cell survival. MG132 is a drug that inhibits I kappa B degradation by the proteasome-avoiding activation of NF-кB. In this work, we studied the sensitizing effect of the MG132 proteasome inhibitor on the antitumor activity of DOX. Methods U937 human leukemia cells were treated with MG132, DOX, or both drugs. We evaluated proliferation, viability, apoptosis, caspase-3, -8, and −9 activity and cleavage, cytochrome c release, mitochondrial membrane potential, the Bcl-2 and Bcl-XL antiapoptotic proteins, senescence, p65 phosphorylation, and pro- and antiapoptotic genes. Results The greatest apoptosis percentage in U937 cells was obtained with a combination of MG132 + DOX. Likewise, employing both drugs, we observed a decrease in tumor cell proliferation and important caspase-3 activation, as well as mitochondrial membrane potential loss. Therefore, MG132 decreases senescence, p65 phosphorylation, and the DOX-induced Bcl-2 antiapoptotic protein. The MG132 + DOX treatment induced upregulation of proapoptotic genes BAX, DIABLO, NOXA, DR4, and FAS. It also induced downregulation of the antiapoptotic genes BCL-XL and SURVIVIN. Conclusion MG132 sensitizes U937 leukemia cells to DOX-induced apoptosis, increasing its anti-leukemic effectiveness.

Abstract
Background WNT signaling pathways are significantly altered during cancer development. Vertebrates possess two classes of WNT signaling pathways: the “canonical” WNT/β-catenin signaling pathway, and the “non-canonical” pathways including WNT/Ca2+ and WNT/Planar cell polarity [PCP] signaling. WNT4 influences hematopoietic progenitor cell expansion and survival; however, WNT4 function in cancer development and the resulting implications for oncogenesis are poorly understood. The aim of this study was twofold: first, to determine the expression of WNT4 in mature peripheral blood cells and diverse leukemia-derived cells including cell lines from hematopoietic neoplasms and cells from patients with leukemia; second, to identify the effect of this ligand on the proliferation and apoptosis of the blast-derived cell lines BJAB, Jurkat, CEM, K562, and HL60. Methods We determined WNT4 expression by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) in peripheral blood mononuclear cells (PBMCs) and T- and B-lymphocytes from healthy individuals, as well as from five leukemia-derived cell lines and blasts derived from patients with leukemia. To analyze the effect of WNT4 on cell proliferation, PBMCs and cell lines were exposed to a commercially available WNT4 recombinant human protein. Furthermore, WNT4 expression was restored in BJAB cells using an inducible lentiviral expression system. Cell viability and proliferation were measured by the addition of WST-1 to cell cultures and counting cells; in addition, the progression of the cell cycle and the amount of apoptosis were analyzed in the absence or presence of WNT4. Finally, the expression of WNT-pathway target genes was measured by qRT-PCR. Results WNT4 expression was severely reduced in leukemia-derived cell lines and blasts derived from patients with leukemia. The exposure of cell lines to WNT4 recombinant protein significantly inhibited cell proliferation; inducing WNT4 expression in BJAB cells corroborated this observation. Interestingly, restoration of WNT4 expression in BJAB cells increased the accumulation of cells in G1 phase, and did not induce activation of canonical WNT/β-catenin target genes. Conclusions Our findings suggest that the WNT4 ligand plays a role in regulating the cell growth of leukemia-derived cells by arresting cells in the G1 cell cycle phase in an FZD6-independent manner, possibly through antagonizing the canonical WNT/β-catenin signaling pathway.

Abstract
BACKGROUND AND AIM The commonly accepted treatment for hepatitis C virus (HCV) infection, pegylated interferon alpha (PEG INF-alpha) and ribavirin, leads to 50-60% of sustained virological response (SVR). On the other hand, pentoxifylline (PTX) possesses antiviral and hepatoprotector properties. AIM To investigate whether the addition of PTX to conventional hepatitis C treatment increases SVR. MATERIAL AND METHODS Seventy two patients of both genders were studied in a randomized fashion; the diagnosis of chronic HCV infection was made according to clinical and laboratory criteria and histopathologically classified according to METAVIR scoring system criteria. HCV viral load was tested by PCR, baseline, and after 6 months of treatment, as well as anti-HCV, anti-hepatitis B virus , and anti-human immunodeficiency virus antibodies by enzyme-linked immunosorbent assay. During 48 weeks, control group patients were treated with PEG INF-alpha- 2a plus ribavirin. PTX was administered to Experimental Group patients prior to the treatment. RESULTS Demographic data were similar in both groups. Experimental- and control-group subjects were at F2 and F3 states according to the METAVIR classification. The most common HCV genotypes were 1a and 1b (39% in the control group in each case, and 42% in the experimental group in each case). At the end of the study, hepatic enzymes and viral load decreased in both groups to similar values. SVR in the experimental group increased significantly (p < 0.05) when compared with standard therapy alone. CONCLUSION Addition of PTX to conventional chronic hepatitis C treatment may increase the percentage of patients with SVR.

Abstract
Background In Oncology, the resistance of the cancerous cells to chemotherapy continues to be the principal limitation. The nuclear factor-kappa B (NF-κB) transcription factor plays an important role in tumor escape and resistance to chemotherapy and this factor regulates several pathways that promote tumor survival including some antiapoptotic proteins such as Bcl-2 and Bcl-XL. In this study, we investigated, in U937 human leukemia cells, the effects of PTX and the MG132 proteasome inhibitor, drugs that can disrupt the NF-κB pathway. For this, we evaluated viability, apoptosis, cell cycle, caspases-3, -8, -9, cytochrome c release, mitochondrial membrane potential loss, p65 phosphorylation, and the modification in the expression of pro- and antiapoptotic genes, and the Bcl-2 and Bcl-XL antiapoptotic proteins. Results The two drugs affect the viability of the leukemia cells in a time-dependent manner. The greatest percentage of apoptosis was obtained with a combination of the drugs; likewise, PTX and MG132 induce G1 phase cell cycle arrest and cleavage of caspases -3,-8, -9 and cytochrome c release and mitochondrial membrane potential loss in U937 human leukemia cells. In these cells, PTX and the MG132 proteasome inhibitor decrease p65 (NF-κB subunit) phosphorylation and the antiapoptotic proteins Bcl-2 and Bcl-XL. We also observed, with a combination of these drugs overexpression of a group of the proapoptotic genes BAX, DIABLO, and FAS while the genes BCL-XL, MCL-1, survivin, IκB, and P65 were downregulated. Conclusions The two drugs used induce apoptosis per se, this cytotoxicity was greater with combination of both drugs. These observations are related with the caspases -9, -3 cleavage and G1 phase cell cycle arrest, and a decrease in p65 phosphorylation and Bcl-2 and Bcl-XL proteins. As well as this combination of drugs promotes the upregulation of the proapoptotic genes and downregulation of antiapoptotic genes. These observations strongly confirm antileukemic potential.

Abstract
BACKGROUND Due to the complexity of the diabetic foot, its high frequency of amputations and accompanying immunosuppression, treatment is difficult. We tested the usefulness of glycophosphopetical immunoregulator as adjuvant therapy for diabetic foot injury. METHODS We carried out a prospective double-blind randomized controlled study with 19 patients per group with diabetic foot injury III and IV (Wagner injury classification). The study group was treated orally with glycophosphopeptical (1 g/every 8 h for 4 weeks). Control group was treated with placebo. Both groups received conventional treatment: wound debridement, antibiotic therapy and metabolic control. Area and depth of injury was measured at the beginning of the study and after 2 months. Patients who were healed or showed improvement were quantified as well with serum levels of TNF-α, interferon-γ and IL-1β, 15 days after treatment initiation. RESULTS The study group was comprised of 13 males and six females (mean age 61.6 ± 14.9 years) and the control group was comprised of five females and 14 males (mean age 56.7 ± 14.6 years). At the end of the study, the area and depth of the lesions were significantly lower in the study group (p <0.05). There were 13 amputations in the study group vs. 17 in the control group. In the group treated with glycophosphopeptical, there were 15 patient who were healed or improved and four failures vs. seven patients in the control group who were healed or improved and 12 failures. There were only four failures in the study group vs. seven in the control group with 12 failures (p = 0.03). TNF-α was lower in the study group than in the control group (p <0.02). CONCLUSION Glycophosphopeptical is useful as adjuvant therapy in diabetic foot injuries.

Abstract
Background WNT7a, a member of the Wnt ligand family implicated in several developmental processes, has also been reported to be dysregulated in some types of tumors; however, its function and implication in oncogenesis is poorly understood. Moreover, the expression of this gene and the role that it plays in the biology of blood cells remains unclear. In addition to determining the expression of the WNT7A gene in blood cells, in leukemia-derived cell lines, and in samples of patients with leukemia, the aim of this study was to seek the effect of this gene in proliferation. Methods We analyzed peripheral blood mononuclear cells, sorted CD3 and CD19 cells, four leukemia-derived cell lines, and blood samples from 14 patients with Acute lymphoblastic leukemia (ALL), and 19 clinically healthy subjects. Reverse transcription followed by quantitative Real-time Polymerase chain reaction (qRT-PCR) analysis were performed to determine relative WNT7A expression. Restoration of WNT7a was done employing a lentiviral system and by using a recombinant human protein. Cell proliferation was measured by addition of WST-1 to cell cultures. Results WNT7a is mainly produced by CD3 T-lymphocytes, its expression decreases upon activation, and it is severely reduced in leukemia-derived cell lines, as well as in the blood samples of patients with ALL when compared with healthy controls (p ≤0.001). By restoring WNT7A expression in leukemia-derived cells, we were able to demonstrate that WNT7a inhibits cell growth. A similar effect was observed when a recombinant human WNT7a protein was used. Interestingly, restoration of WNT7A expression in Jurkat cells did not activate the canonical Wnt/β-catenin pathway. Conclusions To our knowledge, this is the first report evidencing quantitatively decreased WNT7A levels in leukemia-derived cells and that WNT7A restoration in T-lymphocytes inhibits cell proliferation. In addition, our results also support the possible function of WNT7A as a tumor suppressor gene as well as a therapeutic tool.

Abstract
Background The Three-amino acid-loop-extension (TALE) superfamily of homeodomain-containing transcription factors have been implicated in normal hematopoiesis and in leukemogenesis and are important survival, differentiation, and apoptosis pathway modulators. In this work, we determined the expression levels of TALE genes in leukemic-derived cell lines, in blood samples of patients with Acute lymphoblastic leukemia (ALL), and in the blood samples of healthy donors. Results Here we show increased expression of MEIS1, MEIS2, and PREP1 genes in leukemia-derived cell lines compared with blood normal cells. High levels of MEIS1 and PREP1, and low levels of PBX4 expression were also founded in samples of patients with ALL. Importantly, silencing of MEIS1 decreases the proliferation of leukemia-derived cells but increases their survival after etoposide treatment. Etoposide-induced apoptosis induces down-regulation of MEIS1 expression or PREP1 up-regulation in chemotherapy-resistant cells. Conclusions Our results indicate that up-regulation of MEIS1 is important for sustaining proliferation of leukemic cells and that down-regulation of MEIS1 or up-regulation of PREP1 and PBX genes could be implicated in the modulation of the cellular response to chemotherapeutic-induced apoptosis.

Abstract
BACKGROUND The aim of this work was to determine and compare plasma levels of proinflammatory cytokines (IL-1beta, IL-6 and TNF-alpha), C-reactive protein (CRP) and lipoperoxides in patients submitted to laparoscopic cholecystectomy under general anesthesia or regional anesthesia. METHODS Two groups of 15 patients of both sexes were submitted to laparoscopic cholecystectomy either with general or regional anesthesia. In all cases we obtained three samples of plasma. The first sample was collected immediately before surgery, whereas the other samples were collected 60 min and 24 h after the cholecystectomy. Using commercial kits, plasma levels of IL-1beta, IL-6 and TNF-alpha were quantified by ELISA, whereas lipoperoxides were determined by a colorimetric method. The ultrasensitive CRP was determined in the hospital by the Prestige 24I automated method. RESULTS In all determinations, proinflammatory cytokines increased 24 h after surgery except plasma levels of IL-1beta in the regional anesthesia group. Comparison of the two different groups showed that the general anesthesia group had a similar or higher quantity of proinflammatory cytokines and oxidative stress when compared to the regional anesthesia group (p <0.05). In contrast, plasma levels of CRP were lower in the general anesthesia group (p <0.005). CONCLUSIONS The type of anesthesia influences in a different manner the secretion of soluble mediators of inflammation. These observations may have important clinical repercussions.

Abstract
BACKGROUND Chemotherapy is effective against a wide variety of tumor cells, although its use is limited by side effects. In vitro experiments and phase I and II trials have shown that phytochemicals such as perillyl alcohol (P-OH) have antitumor effects. Pentoxifylline (PTX), a synthetic methylxanthine used mainly to treat pathologies associated with hematological diseases, sensitizes tumor cells to chemotherapy. The aim of this study was to determine whether PTX amplifies the antitumor effects of P-OH in U937 human myelomonocytic leukemia cells. METHODS Apoptosis was measured by the loss of mitochondrial membrane potential determined by flow cytometry using dihexyloxacarbocyanine iodide (DiOC6) and propidium iodide. Bcl-2 and Bax protein expression was also assessed by Western blot analysis. RESULTS P-OH and PTX induced loss of the mitochondrial membrane potential in U937 cells in vitro. Culturing the cells in the presence of both compounds caused a significant increase (p < 0.001) in apoptosis and expression of anti-apoptotic Bcl-2 and pro-apoptotic Bax proteins. However, despite their coexistence, Bax expression prevailed in our experiments. These data suggest that the effects of PTX might be attributable to changes in the mitochondrial membrane potential. CONCLUSION PTX sensitizes tumor cells to the anti-neoplastic action of P-OH. These observations may have clinical relevance in the treatment of cancer patients.

Abstract
UNLABELLED The aim of this work was to investigate whether in vivo and in vitro pentoxifylline (PTX) sensitizes hematological tumor cells to adriamycin (ADM)-induced apoptosis, and to investigate the involvement of caspase cascades and phosphorylated forms of IkappaBalpha. Balb/c mice inoculated intraperitoneally with L5178-Y murine lymphoma cells were used for in vivo experiments and for survival studies. The U937 human monocytic cell line was used for in vitro experiments. Both cell lines were treated under similar experimental conditions with PTX and/or ADM to assess their effects on apoptosis. Apoptosis was evaluated by fluorescence microscopy with ethidium bromide and acridine orange staining and confirmed by electrophoretic DNA analysis. Caspase inhibitors Z-VAD-fmk, Z-DEVD-fmk, and Z-LEHD-fmk were used to investigate the involvement of caspase cascades. C-terminally and Ser32 phosphorylated forms of IkappaBalpha were evaluated in cytoplasmic extracts in the absence or presence of TNFalpha. RESULTS In vivo, PTX (50 mg/kg) with ADM (5 mg/kg) increased the apoptotic index relative to PTX or ADM administered alone, time- and dose-dependently. DNA laddering appeared in lymphoma cells treated with PTX+ADM at 24 h, whereas neither untreated control, PTX-, nor ADM-treated cells showed DNA fragmentation. All (100%) tumor-bearing mice treated with PTX (25 mg/kg)+ADM (2.5 mg/kg) survived for 1 year, whereas the mortality rates of mice treated with either PTX or ADM alone at the same doses were similar to that of untreated tumor-bearing mice (28+/-3 days). Caspase inhibitors inhibited apoptosis more efficiently in PTX- or ADM-treated cultures than in PTX+ADM-treated cultures. Pretreatment with TNFalpha (10 ng/mL) increased apoptosis in PTX- or ADM-treated U937 cells. However, the apoptotic index of PTX+ADM-treated cultures was significantly reduced and the expression of C-terminally and Ser32 phosphorylated IkappaBalpha was reduced. PTX sensitizes hematological malignancies to ADR-induced apoptosis. An independent caspase pathway is involved in PTX+ADM-induced apoptosis. The phosphorylation status of IkappaBalpha is closely related via TNFalpha to the possible mechanisms of drug resistance.

Abstract
INTRODUCTION There is some evidence that retinopathy of prematurity is due to excessive oxidative stress on the developing retina caused by high free radical production or reduced ability to eliminate these radicals. OBJECTIVE To determine the relationship between high levels of oxidative stress and retinopathy of prematurity. MATERIAL AND METHODS A prospective cohort study was designed. Fifty premature infants of less than 33 weeks' gestational age were included. Serum lipoperoxide levels were determined as a measure of oxidative stress. Samples were taken once a week for 1 month, starting from the first week of life. The results of all four samples were compared between infants who developed any degree of retinopathy of prematurity and those without it. Ophthalmological examinations were performed after the fourth week of life. RESULTS The incidence of retinopathy of prematurity was 22 % (11/50). The mean values of all the samples showed a significant difference between infants who developed retinopathy of prematurity (5.44 +/- 1.30 nmol/ml) and those who did not (2.94 +/- 0.89 nmol/ml, p = 0.0001). The relative risk of developing retinopathy of prematurity with high serum lipoperoxide levels was 5.15, 5.63, 4.15 and 12.70 for each of the weekly samples. CONCLUSIONS There is an association between high serum lipoperoxide levels, as a measure of oxidative stress, and the incidence of retinopathy of prematurity.

Abstract
Apoptosis was followed in L5178Y lymphoma cell-bearing mice at different times after intraperitoneal injections of adriamycin (ADM). Apoptosis was determined morphologically and confirmed by DNA laddering on electrophoresis. Apoptosis was observed 36h after injection of 5mg/kg ADM (apoptotic cell index 64.2+/-5.6 vs. 1.5+/-2.1 from the untreated group) and confirmed by DNA electrophoresis. However, when the animals were pretreated with (+)-alpha-tocopherol acid succinate or superoxide dismutase before ADM administration apoptotic index significantly diminished (P<0.05) and the DNA electrophoresis did not show fragmentations. We conclude that in ADM-treated mice, tumour cell death occurs in two ways: first by necrosis, then later by apoptosis. These observations are likely to be associated with or caused by the generation of reactive oxygen species.

Abstract
The in vivo and in vitro development of apoptosis induced by gamma-irradiation was studied in mouse peritoneal macrophages. The apoptosis index was measured by fluorescence microscopy and DNA electrophoresis. In vivo apoptosis was greatest eight days after 8 Gy total body gamma-irradiation. A DNA ladder electrophoretic pattern was only observed in the gamma-irradiated group. The participation of reactive oxygen species in apoptosis induction was investigated by pretreating mice with the antioxidants superoxide dismutase, catalase, vitamin E or lipopolysaccharide before gamma-irradiation. Measurement of serum lipoperoxides showed oxidative stress in the gamma-irradiated mice and the protection given by the antioxidants. These results were confirmed using in vitro cultures of peritoneal macrophages: gamma-irradiated groups and antioxidant-pretreated gamma-irradiation groups showed results similar to those observed with in vivo irradiation. A loss of mitochondrial membrane potential (delta psi(m)) was also observed by microscopy in the gamma-irradiated cell cultures. Experiments with caspase inhibitors confirmed the participation of caspase 3 and caspase 9.

Abstract
BACKGROUND Adriamycin (ADM) is a potent antitumor drug that induces apoptosis (AP) in tumor cells. AP is modulated by caspases and by mitogen-activated protein kinases (MAPK) as well as by the mitochondrial membrane potential (deltapsim). We studied the participation of these systems in peritoneal macrophages from ADM-treated mice. MATERIALS AND METHODS Balb/c mice were either treated with ADM (5 mg/kg, i.p.) or with 0.85% NaCl solution (controls). One hour later, peritoneal cells were harvested and cultured for 28 h. AP was evaluated by ethidium bromide and acridine orange staining; deltapsim was monitored using a MitoCapture stain Kit; DNA integrity was assessed by electrophoretic analysis. Animals were treated (i.p.) 1 h before ADM administration with Z-LEHD-FMK, Z-DEVD-FMK, or Z-VAD-FMK (caspase-9, caspases-3, 7,10 and general caspase inhibitors, respectively) or with PD169316 (a MAPKp38 inhibitor). RESULTS ADM induced a higher rate of AP and the characteristic electrophoretic DNA ladder pattern. Mice treated with caspases inhibitors plus ADM showed significant reductions in AP and DNA laddering; in contrast, no differences were observed in mice treated with PD169316 plus ADM in comparison with ADM alone. ADM also induced early loss of the deltapsim. CONCLUSION In these experimental conditions, ADM induced AP in a mainly caspase-9-dependent manner and this was related to a reduction in the deltapsim.

Abstract
Introducción. La Amikacina (AMK) es un antibiótico de la familia de los aminoglucósidos, utilizado contra bacterias gram negativas en el recién nacido. En su empleo es necesario obtener concentraciones séricas definidas para obtener la mejor eficiencia con la mínima toxicidad. Generalmente los esquemas clásicos llevan a concentraciones plasmáticas más elevadas que las recomendadas. Por esta razón nosotros utilizamos un esquema que considera el peso, la edad gestacional y postnatal al mismo tiempo, dado que las constantes fisiológicas del recién nacido cambian rápidamente.
Material y métodos. Este protocolo se comparó con el que se emplea de rutina en nuestro Hospital que no considera la edad postnatal. El estudio se realizó en 112 prematuros en el cual se formaron 4 grupos distribuidos de acuerdo a su edad gestacional y postnatal. Todos los RN recibieron AMK a dosis de 7.5 mg/Kg de peso, sólo difirieron los tiempos de administración. En nuestro esquema la administración de AMK fue la siguiente: cada 24 horas para prematuros menores de 33 semanas de gestación mayores o menores de 7 días de vida, cada 18 horas para los prematuros de 33 a 36 semanas de gestación con menos de 7 días de vida y cada 12 horas para aquellos de 7 a 21días.
Resultados. Las concentranciones séricas de AMK pico y valle se mantuvieron dentro de los límites recomendados.
Discusión. Estos resultados nos permiten recomendar este esquema de tratamiento en hospitales donde no se cuenta con soporte tecnológico para la determinación de la AMK.

Abstract
Aclacinomycin (ACM) is an oncostatic of the anthracycline family, largely used in patients and experimentally in mice. ACM has been reported to enhance phagocytosis, secretion of free oxygen radicals and of interleukin 1. Its injection is also followed by an increase of the cytotoxic and cytostatic activity of murine peritoneal macrophages. In the present work we investigated whether ACM modifies the antigen-presenting cell capacity of murine peritoneal macrophages. Purified T lymphocytes were cultured with peritoneal macrophages from either normal or ACM treated mice (4 mg/kg day -4) which were previously incubated with phytohemagglutinin. The T cell proliferative response was greater in cultures with normal macrophages, indicating that macrophages from ACM-treated mice had a better antigen presenting activity than normal untreated macrophages.
