Prostate cancer is the most common malignancy diagnosed in men in the western world. The development of distant metastases and therapy resistance are major clinical problems in the management of prostate cancer patients. In order for prostate cancer to metastasize to distant sites in the human body, prostate cancer cells have to migrate and invade neighboring tissue. Cancer cells can acquire a migratory and invasive phenotype in several ways, including single cell and collective migration. As a requisite for migration, epithelial prostate cancer cells often need to acquire a motile, mesenchymal-like phenotype...

Periprosthetic osteolysis belongs to osteolytic diseases, which often occur due to an imbalance between osteoclast and osteoblast number or activity. Fraxetin, a natural plant extract, inhibits osteoblast apoptosis and has therapeutic potential for treating osteolytic diseases. However, data pertaining to the effects of fraxetin on osteoclasts are limited. In the present study, it was demonstrated that the inhibition of osteoclastogenesis by fraxetin had an important role on the therapy of titanium particle‑induced osteolysis in vivo...

The recent development in immune checkpoint inhibitors and chimeric antigen receptor (CAR) T-cells in the treatment of cancer has not only demonstrated the potency of utilising T-cell reactivity for cancer therapy, but has also highlighted the need for developing new approaches to discover targets suitable for such novel therapeutics. Here we analysed the immunopeptidomes of 6 HLA-A2-positive triple negative breast cancer (TNBC) samples by nano-ultra performance liquid chromatography tandem mass spectrometry (nUPLC-MS2 )...

Programmed cell death ligand 1 (PD-L1) interacts with programmed cell death protein-1 (PD-1) as an immune checkpoint. Reactivating the immune response by inhibiting PD-L1 using therapeutic antibodies provides substantial clinical benefits in many, though not all, melanoma patients. However, transcriptional suppression of PD-L1 expression as an alternative therapeutic anti-melanoma strategy has not been exploited. Here we provide biochemical evidence demonstrating that ultraviolet radiation (UVR) induction of PD-L1 in skin is directly controlled by nuclear factor E2-related transcription factor 2 (NRF2)...

Background: Development of innovative immunotherapy is imperative to improve the poor survival of the nasopharyngeal carcinoma (NPC) patients. In this study, we evaluated the T cell response to melanoma-associated antigen (MAGE)-A1, MAGE-A3, or synovial sarcoma X-2 (SSX-2) in the peripheral blood of treatment-naive NPC patients. The relationship of responses among the three proteins and the human leukocyte antigen (HLA)-A types were analyzed to provide evidence of designing novel therapy...

Since reprogramming energy metabolism is considered a new hallmark of cancer, tumor metabolism is again in the spotlight of cancer research. Many studies have been carried out and many possible therapies have been developed in the last years. However, tumor cells are not alone. A series of extracellular components and stromal cells, such as endothelial cells, cancer-associated fibroblasts, tumor-associated macrophages, and tumor-infiltrating T cells, surround tumor cells in the so-called tumor microenvironment (TME)...

Primary liver cancer is a common kind of digestive cancers with high malignancy, causing 745,500 deaths each year. Hepatocellular carcinoma is the major pathological type of primary liver cancer. Traditional treatment methods for patients with hepatocellular carcinoma have shown poor efficacy in killing residual cancer cells for a long time. In recent years, tumor immunotherapy has emerged as a promising method owing to its safety and efficacy with respect to delaying the progression of advanced tumors and protecting postoperative patients against tumor relapse and metastasis...

Although germline alterations and somatic mutations in disease cells have been extensively analyzed, molecular changes in immune cells associated with disease conditions have not been characterized in depth. It is clear that our immune system has a critical role in various biological and pathological conditions, such as infectious diseases, autoimmune diseases, drug-induced skin and liver toxicity, food allergy, and rejection of transplanted organs. The recent development of cancer immunotherapies, particularly drugs modulating the immune checkpoint molecules, has clearly demonstrated the importance of host immune cells in cancer treatments...

Acute lymphoblastic leukemia (ALL) comprises a heterogeneous group of diseases with different morphologic, cytogenetic, and molecular subgroups, some of which have significant therapeutic implications. It typically presents with an aggressive clinical course, and among adults, responds poorly to standard chemotherapy, and carries a high risk for relapse. Despite the significant progress made in inducing remission, frequent relapses remain a challenge. Novel drugs, such as potent later-generation tyrosine kinase inhibitors, antibody-drug conjugates, bispecific monoclonal antibodies, and chimeric antigen receptor (CAR) T-cell therapies, are being investigated in patients with ALL...

PURPOSE: Radiation is used extensively to treat localized cancer, but improved understanding of its effects on the immune system have increased interest in its potential systemic (abscopal) effects, particularly in combination with checkpoint inhibitors such as anti-PD1. The majority of patients either do not respond or develop resistance to monotherapy over time. Here, we investigated the efficacy of OX40 (CD134) stimulation as an alternative immunotherapeutic approach in combination with radiotherapy (XRT) in a murine model of anti-PD1-resistant lung tumors...

PURPOSE: High-risk neuroblastoma is an aggressive disease. DNA sequencing studies have revealed a paucity of actionable genomic alterations and a low mutation burden, posing challenges to develop effective novel therapies. We used RNA sequencing (RNA-seq) to investigate the biology of this disease including a focus on tumor-infiltrating lymphocytes (TILs). EXPERIMENTAL DESIGN: We performed deep RNA-seq on pre-treatment diagnostic tumors from 129 high-risk and 21 low- or intermediate-risk patients with neuroblastomas...

BACKGROUND: Tumor-promoting inflammation is an emerging hallmark of cancer, which participates in both cancer progression and immune escape. Hepatocellular carcinoma (HCC) is a typical inflammation-related cancer with an extremely poor prognosis. Frankincense and myrrh are anti-inflammation agents commonly used in clinic. The purpose of this study is to investigate whether extract of frankincense and myrrh (FM) downregulates inflammatory microenvironment of HCC and thereby restores antitumor immune responses...

The rapid antitumor cytokine production and direct cytotoxicity confer invariant NKT (iNKT) cells ideal candidates for cancer therapy. However, the therapeutic potential of iNKT cells in T-cell malignant diseases remains elusive, as antigen presentation by T cells (T-T presentation) has been suggested to induce hyporesponsiveness of iNKT cells. In this study, we found discrepancies in iNKT cell responses against two T cell-origin cell lines (Jurkat and Molt-4). Human iNKT cells exhibited more intensive cytotoxicity and less efficient cytokine production in response to Fas-bearing Jurkat cells than those to the Fas-negative tumor cells (Molt-4 and myeloid-derived K562)...

Loss of photoreceptors and other retinal cells is a common endpoint in retinal degenerate (RD) diseases that cause blindness. Retinal transplantation is a potential therapy to replace damaged retinal cells and improve vision. In this study, we examined the development of human fetal retinal sheets with or without their retinal pigment epithelium (RPE) transplanted to immunodeficient retinal degenerate rho S334ter-3 rats. Sheets were dissected from fetal human eyes (11-15.7 weeks gestation) and then transplanted to the subretinal space of 24-31 d old RD nude rats...

In recent years the number of articles on damages of high-density lipoproteins (HDL) properties in patients with atherosclerosis has sharply increased. First, it concerns their ability to accept cholesterol (CH) from macrophages - the basis of antiatherogenic action of HDL. This ability was assessed ex vivo - by activity of cell cholesterol (CH) efflux to HDL or into patient's serum. In many works inverse relationship was shown between CH acceptor capacity of HDL and severity of atherosclerotic disease or frequency of its exacerbations during long-term observation, independent from HDL CH concentration...

Beta cell replacement has the potential to restore euglycemia in patients with insulin dependent diabetes. While great progress has been made in establishing allogeneic islet transplantation from deceased donors as the standard of care for those with the most labile diabetes, it is also clear that the deceased donor organ supply cannot possibly treat all those who could benefit from restoration of a normal beta cell mass, especially if immunosuppression were not required. Against this background, the International Pancreas and Islet Transplant Association (IPITA) in collaboration with the Harvard Stem Cell Institute (HSCI), the Juvenile Diabetes Research Foundation (JDRF), and the Helmsley Foundation held a 2-day Key Opinion Leaders Meeting in Boston in 2016 to bring together experts in generating and transplanting beta cells derived from stem cells...

BACKGROUND: Mechanisms leading to neurocognitive impairment (NCI) in people living with HIV (PLWHIV) on stable antiretroviral therapy (cART) remain unknown. We investigated the association between CMV immunity, HIV-specific variables and NCI in PLWHIV on stable cART and with low comorbidity. METHODS: 52 PLWHIV on stable cART and 31 HIV-uninfected controls matched on age, gender, education and comorbidity were tested with a neurocognitive test-battery and CMV-immunoglobulin G (CMV-IgG) levels were measured...

The population is aging, and the prevalence of chronic wounds is increasing. Because neovascularization is essential for tissue repair and both local and systemic factors affect new blood vessel formation, we hypothesize that altering either pathway would reciprocally enhance wound healing in the aged. To test this hypothesis, p53 was locally suppressed and endothelial progenitor cells (EPCs) were systemically mobilized in a murine model of senescent wound healing.Bilateral 6-mm full-thickness stented wounds were made on the dorsum of Zmpste24 mice...
