Abstract
Background Classic Kaposi sarcoma (CKS) is a vascular sarcoma associated with human herpesvirus 8 (HHV-8), which is known to be more common in Mediterranean elderly men and is characterized by indolent clinical behavior. Xinjiang province in China is considered an endemic region for Kaposi’s sarcoma-associated herpesvirus (KSHV), with higher incidence among adults of Kazak and Uyghur ethnicities. Cases of CKS are rarely reported in inland China. Here, we followed a case of CKS for 7 years in a patient of Miao ethnic background in southwestern China. Case presentation A 63-year-old Miao (southwestern China) man was initially diagnosed with CKS in 2010, having a history of limb lesions for 37 years, with left eyelid and binaural lesions for 9 years. He did not have sexual contact with men and was human immunodeficiency virus (HIV)-negative. Due to his lumbago and fever, spinal tuberculosis in the lumbar vertebra was highly suspected after computed tomography (CT) scan. However, diagnostic antituberculosis treatment for 4 weeks failed. The patient was followed up in 2016, when the rash was recovering as the systemic symptoms improved. A new CT was performed, which showed a partial response despite the absence of any medical treatment. The open reading frame (ORF)-K1 of KSHV from skin tissue of the foot was amplified and sequenced, and K1 belonged to subtype A. This genotype is consistent with the typical subtype present in Xinjiang. Conclusions We describe spontaneous partial regression of CKS in a patient of Miao ethnicity in inland China. Our sample may represent an unknown, novel genotype. Surveillance and regulating the immune state may represent a valuable approach for this rare disease.

Abstract
While Kaposi's sarcoma (KS) was common in the 1980s and early 1990s in HIV-positive patients and one of the most common AIDS-defining diseases, its prevalence today has decreased significantly due to the early and widespread use of chimeric antigen receptor T-cell (cART) therapy. The rapid initiation of cART or, if occurring during ongoing cART, an optimization of antiretroviral therapy leads to a healing of this tumour disease in most patients. The aim of the therapy is immune reconstitution, as the immunodeficiency resulting from the HIV disease (reduced CD4+-T helper cells) promotes the development and spread of KS. This case report describes the course of KS in the first diagnosis of AIDS in a 36-year-old patient. The HIV copy count was below the detection limit and the CD3+/CD4+ T-helper cell count was only slightly below the normal value in the six-month follow-up after initial diagnosis and initiation of cART therapy. However, the clinical findings in the one-year follow-up showed only a partial response, whereby it was noted that new tumour lesions also developed focally in addition to individual progressive lesions. This was demonstrated clinically, dermatoscopically and by laser Doppler fluxmetry measurements of the lesions. Such a progression was observed in about one-third of the patients affected in various studies and is called Immune Reconstitution Inflammatory Syndrome. Other therapies in addition to cART are necessary here to suppress this immunological phenomenon (including cytostatic drugs). Promising studies are currently underway, including utilising checkpoint inhibitors. These are of great therapeutic interest due to the high immunological activity of KS itself and usually of systemic inflammatory response syndrome.

Abstract
BACKGROUND: Kaposi’s sarcoma (KS) is a tumour of endothelial, blood and lymphatic cells, caused by an infection with human herpesvirus-8 (HHV-8). The skin lesions of KS, especially of the classical or Mediterranean variant (CKS), are represented by red-purple macules, plaques and nodules, localised mainly on the extremities. CASE REPORT: This case series intend to describe multifocal atypical kaposian manifestations in two HIV negative subjects, affected by CKS, treated with successful chemotherapy. CONCLUSIONS: Although atypical manifestations are extremely rare events, we suggest an accurate, objective examination because a prompt diagnosis can lead to a vital intervention in the patient’s health and sometimes to the identification of the disease itself.

Abstract
BACKGROUND: Kaposi’s sarcoma was first described in 1872 by Moritz Kaposi. To date, it is considered a malignant disease is originating from the endothelial cells of the lymphatic vessels believed to be infected with HHV-8. The current classification defines four major epidemiological forms of Kaposi’s sarcoma: classical, endemic, AIDS-associated, and iatrogenic. CASE REPORT: A 90-year-old male is presented with multiple plaques- and tumour-shaped brown-violet formations located on an erythematous-livid base in the area of both feet and both shanks. Two samples were taken from the lesions on the skin of the shanks, with histopathological examination and the subsequent immunohistochemistry showing Kaposi’s sarcoma. CONCLUSIONS: Kaposi sarcoma is a disease that causes difficulties both in diagnostic and therapeutic respect. The only sure way to determine the correct diagnosis is immunohistochemical staining with the anti-HHV8 antibody. Despite the wide range of systematic and local treatment options, there is still no unified algorithm and a unified strategy for the treatment of Kaposi’s sarcoma.

Abstract
Kaposi's sarcoma-associated herpesvirus (KSHV) is etiologically related to Kaposi's sarcoma (KS), primary effusion lymphoma (PEL) and multicentric Castleman's disease (MCD). It typically displays two different phases in its life cycle, the default latency and occasional lytic replication. The epigenetic modifications are thought to determine the fate of KSHV infection. Previous studies elegantly depicted epigenetic landscape of latent viral genome in in vitro cell culture systems. However, the physiologically relevant scenario in clinical KS tissue samples is unclear. In the present study, we established a protocol of ChIP-Seq for clinical KS tissue samples and mapped out the epigenetic landscape of KSHV genome in classic KS tissues. We examined AcH3 and H3K27me3 histone modifications on KSHV genome, as well as the genome-wide binding sites of latency associated nuclear antigen (LANA). Our results demonstrated that the enriched AcH3 was mainly restricted at latent locus while H3K27me3 was widespread on KSHV genome in classic KS tissues. The epigenetic landscape at the region of vIRF3 gene confirmed its silenced state in KS tissues. Meanwhile, the abundant enrichment of LANA at the terminal repeat (TR) region was also validated in the classic KS tissues, however, different LANA binding sites were observed on the host genome. Furthermore, we verified the histone modifications by ChIP-qPCR and found the dominant repressive H3K27me3 at the promoter region of replication and transcription activator (RTA) in classic KS tissues. Intriguingly, we found that the TR region in classic KS tissues was lacking in AcH3 histone modifications. These data now established the epigenetic landscape of KSHV genome in classic KS tissues, which provides new insights for understanding KSHV epigenetics and pathogenesis. Epigenetic modifications are thought to determine the fate of KSHV infection. The epigenetic landscape of KSHV genome in in vitro cell culture systems was well studied previously. However, the physiologically relevant scenario in clinical KS tissues is unclear. In this study, we performed ChIP-Seq experiments in classic KS tissues and mapped out the AcH3 and H3K27me3 histone modifications on KSHV genome, as well as the genome-wide LANA binding sites. The results revealed a similar H3K27me3 landscape but distinct AcH3 patterns on the KSHV genome compared to the results from in vitro cultured PEL and KSHV infected SLK cells. Intriguingly, there were different LANA binding sites seen on the host genome and a reduced number of AcH3 histone modifications at the TR region of KSHV genome were found. The established epigenetic landscape of KSHV genome in classic KS tissues provides new insights towards our understanding of KSHV epigenetics, which is important for future studies on the mechanism of KSHV infection and pathogenesis.

Abstract
Lenalidomide, an oral immunomodulating agent, has shown promising activity in HIV-infected individuals with Kaposi's sarcoma (KS). This single-arm, multicenter, open-label, Gehan's two-stage phase II trial evaluated the efficacy and safety of lenalidomide in HIV-infected patients with progressive KS despite previous chemotherapy (NCT01282047, ANRS 154 Lenakap trial). The primary endpoint was the rate of partial response (PR) or complete response (CR) at week 24, evaluated by both the study investigators and the patients using the Physical Global Assessment (PGA). AIDS Clinical Trials Group (ACTG) criteria for KS treatment evaluation were used as a secondary endpoint. The data and safety monitoring board recommended that enrollments be halted on April 24, 2013, because of lack of responses. We enrolled 12 antiretroviral-treated HIV-infected men with progressive KS despite previous chemotherapy. Their HIV plasma viral load was <50 copies/ml and their median CD4 cell count 444/mm3. One patient stopped taking lenalidomide because of hives at week 1 and a second patient died at week 7. The remaining 10 patients were assessable at week 24, when none had PGA-defined CR or PR and one had ACTG-defined PR. There were no additional PGA responses at week 48, but an additional three patients had ACTG responses, for a total of four patients with ACTG PR at week 48 (40%; 95% confidence interval: 12.2-73.8). Fourteen grade 3-4 adverse events were considered at least possibly related to lenalidomide during a total of 101 cycles. Lenalidomide was well tolerated in antiretroviral experienced patients with progressive KS previously treated with chemotherapy. The ACTG-defined response rate at week 48 was 40%, while it was 0% using PGA criteria.

Abstract
Retinoids are natural and synthetic vitamin A analogs with effects on cell proliferation, differentiation, and apoptosis. They have significant activity in hematologic malignancies and have been studied extensively in cutaneous T-cell lymphoma. Retinoids bind to nuclear receptors and exert their effects through moderation of gene expression. Retinoic acid receptor and retinoic X receptor exert regulatory activity in vivo, binding to distinct ligands. Studies investigating systemic retinoids as monotherapy and in combination with other agents active against cutaneous lymphoma are reviewed. Side effects associated with retinoids include teratogenicity, dyslipidemias, and hypothyroidism, which should be carefully monitored in patients receiving treatment.

Abstract
Kaposi's sarcoma (KS) is an AIDS-defining cancer caused by the KS-associated herpesvirus (KSHV). KS tumors are composed of KSHV-infected spindle cells of vascular origin with aberrant neovascularization and erythrocyte extravasation. KSHV genes expressed during both latent and lytic replicative cycles play important roles in viral oncogenesis. Animal models able to recapitulate both viral and host biological characteristics of KS are needed to elucidate oncogenic mechanisms, for developing targeted therapies, and to trace cellular components of KS ontogeny. Herein, we describe two new murine models of Kaposi's sarcoma. We found that murine bone marrow-derived cells, whether established in culture or isolated from fresh murine bone marrow, were infectable with rKSHV.219, formed KS-like tumors in immunocompromised mice and produced mature herpesvirus-like virions in vivo. Further, we show in vivo that the histone deacetylase (HDAC) inhibitor suberoylanilide hydroxamic acid (SAHA/Vorinostat) enhanced viral lytic reactivation. We propose that these novel models are ideal for studying both viral and host contributions to KSHV-induced oncogenesis as well as for testing virally-targeted antitumor strategies for the treatment of Kaposi's sarcoma. Furthermore, our isolation of bone marrow-derived cell populations containing a cell type that, when infected with KSHV, renders a tumorigenic KS-like spindle cell, should facilitate systematic identification of KS progenitor cells.

Abstract
A case of Kaposi's sarcoma (KS) presenting as an immune reconstitution inflammatory syndrome in pregnancy with conservative management is reported. Successful outcomes for mother and baby were achieved. HIV was diagnosed at antenatal booking and highly active antiretroviral therapy commenced at 20 weeks. Multiple lymphadenopathies developed two months later. Excision biopsy of a node confirmed KS. In the absence of advanced disease, she was managed conservatively until delivery. The placenta showed no evidence of KS or human herpes virus 8 (HHV-8). The baby had negative HIV and HHV-8 polymerase chain reaction tests at zero, six and 12 weeks of life. Six months postpartum, the KS had regressed and HHV-8 viral load was undetectable.

Abstract
Thalidomide is an effective drug for chronic inflammatory diseases, but the mechanism underlying its immunomodulatory action remains uncertain. Thalidomide has been reported to clinically improve chronic inflammatory granulomatous disorders. In such disorders, the granulomas consist of epithelioid cells, scattered lymphocytes and multinucleated giant cells (MNGC; Langhans-type cells). The present experimental approach permitted the reproduction of MNGC formation from peripheral blood monocytes and examination of thalidomides effect on it. MNGC can be effectively generated from monocytes cultured in the presence of interleukin-4 (IL-4) and macrophage colony-stimulating factor(M-CSF) for 14 days. Thalidomide can inhibit the formation of MNGC in a dose-dependent manner. MNGC formation was partly inhibited by the presence of neutralizing TNF-alpha antibody in the responses induced by IL-4 and M-CSF. Autocrinal TNF-alpha production and modulation of cadhelin expression to regulate cell adhesion might be involved in this inhibitory action of thalidomide. Our results support thalidomides clinical efficacy in the treatment of chronic granulomatous disorders (granulomatosis).

Abstract
UNLABELLED Kaposi sarcoma (KS) remains a challenge. Its classic or Mediterranean form tends to be benign. In transplant recipients it may be less so. As part of the AIDS pandemic, of which it was an original defining component, it may be life-threatening. It is due to human herpesvirus-8, which is necessary but not sufficient to produce the disease. KS has a low prevalence in the general population of the United States and United Kingdom, with an intermediate rate in Italy and Greece, and a high one in parts of Africa. In Italy, hot spots include its southern regions, the Po River Valley, and Sardinia, possibly related to a high density of blood-sucking insects. An important challenge is to treat KS patients without immunocompromising them. The potential of effective anti-herpes virus therapy and the use of sirolimus in transplantation recipients have added new opportunities for KS prevention. LEARNING OBJECTIVES At the conclusion of this learning activity, participants should be able to provide the most recent information about Kaposi sarcoma in the context in which it occurs. Its classic or Mediterranean form, its pattern in transplant recipients and others iatrogenically immunosuppressed, and its occurrence as a potentially life-threatening part of the AIDS pandemic will be stressed. Its etiology and transmission will be discussed in detail to facilitate understanding of Kaposi sarcoma and of human herpesvirus-8 infection in the general population of the United States and United Kingdom, in Italy and Greece, and in certain parts of Africa. Its therapy, including the concept of doing it without immunocompromising the patient, will be stressed. New opportunities for Kaposi sarcoma prevention will also be discussed.

Abstract
Soft tissue sarcomas are a heterogeneous group of connective tissue tumors, with more than 50 different subtypes. Given the heterogeneity, and the relative small numbers of patients, performing large adequately powered clinical trials in which one can glean any overall broad treatment decisions based on outcome is difficult at best. There is controversy on which chemotherapeutic agents to use in the adjuvant and metastatic settings, or even if to use chemotherapy in the adjuvant setting. In the metastatic setting, doxorubicin and ifosfamide have remained the standards of care for more than 20 years. This review discusses the data on chemotherapy for treatment of metastatic sarcomas and the utility of chemotherapy in the adjuvant and neoadjuvant settings. In addition, the utility of newer biologic agents in the treatment for sarcomas is considered.

Abstract
BACKGROUND Thalidomide has been identified and its anti-inflammatory and immunomodulatory properties clarified. This report expands our report of 2 entero-Behçet disease children who developed significant steroid toxicity and improved dramatically with thalidomide. METHODS We studied the effects of thalidomide in 7 juvenile-onset patients with severe, recurrent intestinal involvement of Behçet disease. Thalidomide was given at an initial dose of 2 mg/kg per day, and the dose was increased to 3 mg/kg per day if necessary (3 of 7 patients) or decreased to 1-0.5 mg/kg per day according to the responses to the drug. RESULTS All 7 patients showed dramatic improvement in clinical symptoms with thalidomide therapy, and they successfully discontinued steroid therapy. Patients receiving thalidomide were monitored for prolonged neurotoxicity, and the treatment and a few side effects were well tolerated by all patients. CONCLUSIONS Our results indicate that thalidomide can be an efficacious medication in appropriately selected patients with some inflammatory bowel diseases with many chances of success.

Abstract
Kaposi's sarcoma-associated herpesvirus (KSHV) is the causal agent of both KS and primary effusion lymphoma (PEL). Although treatment with paclitaxel has significant antitumor activity in KS, drug resistance represents a major obstacle for improving the overall response and survival of PEL patients. The transcriptional pattern of KSHV is cell/tissue specific, as revealed by the fact that the viral latent protein LANA2 is detected exclusively in B cells. This paper focuses on the mechanism of paclitaxel resistance observed in PEL cells. Here we show that LANA2 protein modulates microtubule dynamics through its direct binding to polymerized microtubules, preventing microtubule stabilization induced by paclitaxel. This is the first demonstration of paclitaxel resistance induced by a viral protein and suggests a link between the expression of LANA2 and the resistance of PEL cells to paclitaxel.

Abstract
BACKGROUND Kaposi's sarcoma (KS) is a lymphangioproliferative tumour. Therapy of KS depends on the characteristics of the disease, especially area and growth rate of lesions, and patient condition. Currently symptomatic resectable lesions are excised, whereas more advanced disease and unresectable lesions are treated with radiotherapy. If a large area or internal organs are affected or other treatments fail, chemotherapy is used. Recently some authors have reported their encouraging experience in the use of thalidomide in patients with AIDS-related KS. OBJECTIVE To evaluate the efficacy of thalidomide in 3 patients with non-AIDS-related KS. METHODS Two patients with classic widespread cutaneous and 1 with iatrogenic cutaneous and visceral KS were treated with thalidomide (100 mg/day) for 12 months. RESULTS In all 3 patients partial remission was evident after 4 months of thalidomide therapy; in 2 out of 3 complete remission was achieved after 12 months of treatment. CONCLUSIONS Our results seem to confirm the utility of thalidomide in the treatment of non-AIDS-related KS.

Abstract
A number of lifestyle factors that reduce cancer risk in the primary prevention setting may be potential new targets for use in combination with cancer vaccines. This review discusses the modulation of energy balance (physical activity, calorie restriction, and obesity prevention), and the supplementation with natural and synthetic analogs of vitamins A and E, as potential interventions for use in combination with cancer vaccines. Additionally, the pharmacologic manipulation of nutrient metabolism in the tumor microenvironment (e.g., arachidonic acid, arginine, tryptophan, and glucose metabolism) is discussed. This review includes a brief overview of the role of each agent in primary cancer prevention; outlines the effects of these agents on immune function, specifically adaptive and/or anti-tumor immune mechanisms, when known; and discusses the potential use of these interventions in combination with therapeutic cancer vaccines. Modulation of energy balance through exercise and strategies targeting nutrient metabolism in the tumor microenvironment represent the most promising interventions to partner with therapeutic cancer vaccines. Additionally, the use of vitamin E succinate and the retinoid X receptor-directed rexinoids in combination with cancer vaccines offer promise. In summary, a number of energy balance- and nutrition-related interventions are viable candidates for further study in combination with cancer vaccines.

Abstract
The eye is a common site for complications of human immunodeficiency virus (HIV) infection. Although cytomegalovirus retinitis remains the most prevalent of the blinding ocular disorders that can occur in individuals with the acquired immunodeficiency syndrome (AIDS), several important HIV-associated disorders may involve the anterior segment, ocular surface, and adnexae. Some of these entities, such as Kaposi sarcoma, were well described, but uncommon, before the HIV epidemic. Others, like microsporidial keratoconjunctivitis, have presentations that differ between affected individuals with HIV disease and those from the general population who are immunocompetent. The treatment of many of these diseases is challenging because of host immunodeficiency. Survival after the diagnosis of AIDS has increased among individuals with HIV disease because of more effective antiretroviral therapies and improved prophylaxis against, and treatment of, opportunistic infections. This longer survival may lead to an increased prevalence of anterior segment and external ocular disorders. In addition, the evaluation and management of disorders such as blepharitis and dry eye, which were previously overshadowed by more severe, blinding disorders, may demand increased attention, as the general health of this population improves. Not all individuals infected with HIV receive potent antiretroviral therapy, however, because of socioeconomic or other factors, and others will be intolerant of these drugs or experience drug failure. Ophthalmologists must, therefore, still be aware of the ocular findings that develop in the setting of severe immunosuppression. This article reviews the spectrum of HIV-associated anterior segment and external ocular disorders, with recommendations for their evaluation and management.

Abstract
Suramin inhibits the proliferation of several human tumors in vivo and in vitro. In this study, the effects of Suramin on proliferation and angiogenesis were investigated in human pancreatic cancer cell lines and in an orthotopic nude mouse model of human pancreatic cancer. The effects of Suramin on proliferation, viability, cell cycle, and apoptosis were studied in five human pancreatic cancer cell lines. Suramin inhibited the proliferation of pancreatic cancer cells in a dose-dependent manner and reduced viability at high concentrations. Cell cycle analysis revealed a decreased S-phase fraction in most cell lines, whereas the apoptotic fraction was not notably different. In vivo treatment with Suramin significantly reduced pancreatic tumor size (MiaPaCa-2, -74%; AsPC-1, -41%; and Capan-1, -49%) and metastatic spread (MiaPaCa-2, -79%; AsPC-1, -34%; and Capan, -38%). As a parameter for angiogenic activity, vascular endothelial growth factor (VEGF) secretion was measured, revealing reduced VEGF concentrations under Suramin treatment in both cell culture medium and ascites. Also, microvessel density quantified in primary tumors was reduced in animals treated with Suramin. Therefore, Suramin inhibits the proliferation of human pancreatic cancer in vitro and in vivo. The therapeutic effects seem to involve cell cycle kinetics and may be in part related to the antiangiogenic action of the drug.

Abstract
We have investigated the pharmacokinetics of nevirapine and paclitaxel in a patient who used both drugs concomitantly, as there are strong theoretical indications for a potential pharmacokinetic drug-drug interaction. Plasma concentrations of nevirapine (dose: 200 mg twice daily orally) and paclitaxel (dose: 100 mg/m(2) 3-h i.v. infusion) were determined in a HIV-1-infected patient with Kaposi's sarcoma. Since both drugs are metabolized via the same cytochrome P450 isoenzymes, investigation of a drug-drug interaction was considered important. We found that the plasma concentrations of nevirapine given together with paclitaxel were similar to those given without paclitaxel. The exposures to paclitaxel (AUC(0-infinity) = 3787 h.ng/ml) and its hydroxy metabolites when co-administered with nevirapine were comparable to the mean exposure to paclitaxel and its metabolites from eight historical controls (AUC(0-infinity) = 3614 h.ng/ml) treated with the same dose. No pharmacokinetic drug-drug interaction between nevirapine and paclitaxel could be demonstrated in our HIV-1-infected patient.

Abstract
Infection with human immunodeficiency virus (HIV) and progression to acquired immune deficiency syndrome (AIDS) are associated with a vide variety of morbidities. Local and systemic diseases can develop in association with HIV infection and may manifest themselves as malignancies of the oropharynx. Advances in HIV management, fueled by increasing understanding of molecular pathogenesis, have resulted in marked changes in the prevalence of oral malignant disease. This paper discusses recent trends in the presentation and treatment of malignancies related to HIV and AIDS with an emphasis on malignancies seen in the oral cavity.

Abstract
HIV infection affects residents of all countries of the world, but the greater majority of affected individuals reside in the developing world. In the past decade there have been substantial changes in the management of HIV disease, particularly the introduction of highly active antiretroviral therapy (HAART). Such agents have reduced significantly the morbidity and mortality associated with HIV disease, however, they are not available for most HIV-infected individuals in the developing world. There is now considerable understanding of the molecular epidemiology, transmission and therapy of the common opportunistic oral infections of HIV disease, and as a consequence of improved anti-HIV strategies, the frequency and severity of oral disease associated with HIV infection have reduced considerably, although HAART may predispose to human papilloma virus infection of the mouth and potentially increase the risk of later oral squamous cell carcinoma. Despite advances in clinical care the majority of individuals with HIV disease worldwide will continue to develop oral disease, as they are resident in the developing world and do not have ready access to even simple therapies.

Abstract
Human herpesvirus-8/Kaposi's sarcoma-associated herpesvirus infection is associated with three proliferative disorders in immunocompromised patients - Kaposi's sarcoma, primary effusion lymphoma and multicentric Castleman's disease. These disorders often develop in patients with advanced AIDS who present a number of therapeutic challenges, underscoring the importance of continuing efforts dedicated to basic and clinical research in this field. In the era of highly active antiretroviral therapy, the incidence of AIDS and Kaposi's sarcoma has considerably decreased, presumably due to enhanced anti-Kaposi's sarcoma-associated herpesvirus immune responses, whereas the situation with primary effusion lymphoma and multicentric Castleman's disease is more complex. Based on advances in the understanding of Kaposi's sarcoma-associated herpesvirus-related disorders and availability of antiretroviral agents, current and future therapeutic approaches will be discussed.

Abstract
Staurosporine, an inhibitor of protein kinase C, is a potential antitumor drug and its derivatives are used as anticancer drugs in clinical trials. Human herpesvirus 8 (HHV-8) is implicated in all forms of Kaposi's sarcoma (KS), primary effusion lymphoma (PEL), and multicentric Castleman's disease (MCD), indicating it to be a DNA tumor virus. It is difficult to culture cell lines derived from KS patients; we therefore used a cell line derived from PEL (BCBL-1) to investigate whether staurosporine affects the HHV-8-related tumors. Our results show that staurosporine treatment reduces the cell viability of BCBL-1 cells and causes cell cycle arrest in the G2/M phase. The G2/M arrest was associated with the decrease in the expression of Cdc2 and cyclin B. Furthermore, the induction of the HHV-8 lytic cycle was not observed under the staurosporine treatment.

Abstract
BACKGROUND The objectives of this study were to (1) compare two techniques (computerized image analysis and visual morphological evaluation) for the assessment of fetal forelimb malformations and (2) increase the robustness of the dose-response curve for forelimb and cleft palate malformations resulting from all-trans retinoic acid (RA) exposure in GD 11 mice. METHODS Pregnant CD-1 mice were administered a single oral dose of all-trans RA (0, 2.5, 10, 30, 60, or 100 mg/kg) on GD 11. GD 18 fetuses were examined for malformations using visual morphological scoring and computerized image analysis. RESULTS Dose-dependent changes occurred in the size and shape of the humerus, radius, and ulna based on both assessment methodologies. The most sensitive indicators for the lowest effect level (10 mg/kg) on forelimbs were roundness, a shape measurement determined by image analysis, and visual morphological scoring. For all other bone measurements (proximal and distal width, area, length, and perimeter), the lowest effect level was 30 mg/kg. The maximum effect for limb defects and total malformed fetuses was seen at 60 mg/kg and higher. Incidence of cleft palate increased over the entire range of administered doses reaching a maximum of 74% (100 mg/kg). CONCLUSIONS Overall, results indicate that computerized image analysis was no more sensitive in detecting changes in the humerus, radius, and ulna than gross visual examination. Dose-response modeling of developmental endpoints yielded comparable benchmark dose levels for long bones and cleft palate that ranged from 0.24 to 7.6 mg/kg all-trans RA.
