Numerous germline mutations in the adenomatous polyposis coli (APC) tumor-suppressor gene are responsible for development of multiple adenomatous colorectal polyps with their inevitable progression to cancer. Multiple attempts at dietary and pharmacological prevention of colorectal carcinoma development in patients with familial adenomatous polyposis (FAP) have provided conflicting results. Immunosuppressive treatment with tacrolimus is known to be associated with an increased risk of malignancy and should be avoided in patients with high propensity for development of neoplasia...

Background.: Although a number of risk factors have been associated with invasive fungal disease (IFD), a systematic review of the literature to document pediatric-specific factors has not been performed. Methods.: We used the Ovid SP platform to search Medline, Medline In-Process, and Embase for studies that identified risk factors for IFD in children with cancer or those who undergo hematopoietic stem cell transplantation (HSCT). We included studies if they consisted of children or adolescents (<25 years) who were receiving treatment for cancer or undergoing HSCT and if the study evaluated risk factors among patients with and those without IFD...

The occurrence of hospital-acquired acute gastroenteritis (AGE) is a major concern for public health. RotavirusA (RVA) and norovirus (NoV) are common causes of viral AGE in the pediatric population, and their role in nosocomial infections has been proven, remaining poorly investigated. To investigate RVA and NoV in hospital-acquired AGE, 55 stool samples from children with nosocomial AGE were collected between May 2014 and May 2015. To evaluate virus spreading routes, 51 environmental swabs were collected from staff and patients' rooms...

AIM: Tumor necrosis factor superfamily member 9 (TNFSF9), also known as 4-1BBL and CD137L, has been implicated in cancer immunotherapy due to its function as a T cell costimulator. However, little is known about its direct impact on cancer development, particularly for solid tumors. METHODS: The TNFSF9 expression was examined by immunohistochemistry in 106 pairs of hepatocellular carcinoma (HCC) and the adjacent non-HCC tissues, and by quantitative PCR and Western blot in HCC cell lines...

Placenta-derived mesenchymal stromal cells (MSC) have often been considered to linger behind their equivalents from other tissues, such as MSC from bone marrow, in many aspects including their therapeutic potential in regenerative medicine. Nowadays however, it is clear that certain aspects make placental MSC attractive as a cellular therapy, such as their lack of ethical concerns and ease of isolation from human term placenta, a material long regarded as biological waste. Moreover, placental MSC virtually lack expression of human leukocyte antigens and co-stimulatory molecules, making them very attractive for transplantation in allogeneic settings...

BACKGROUND: Renal cell carcinoma (RCC) is a tumor with immunogenic properties. Soluble interleukin-2 receptor (sIL-2R) has a role in T cell activation and may be important for immune regulation in various conditions, including infections, transplantation rejection, autoimmune inflammatory states, and cancer. We investigated the prognostic value of the serum sIL-2R level in patients with metastatic RCC receiving IFN-alpha and vascular endothelial growth factor (VEGF)-targeting therapy...

Fanconi anemia is a genetic bone marrow failure syndrome, variably associated with congenital anomalies and a sharply increased risk for epithelial malignancies. During the past 20 years, hematopoietic stem cell transplantation (HSCT) has dramatically improved survival. However, compared to the general population, FA patients are at greatly increased risk, and at a much younger age, for squamous cell carcinomas (SCC) of the oral cavity, esophagus and the anogenital region. The relative risk and age of onset appears to negatively correlate with HSCT in FA patients...

Hepatocellular carcinoma (HCC) is a cause of several deaths related to cancer worldwidely. In early stage, curative treatments such as surgical resection, liver transplant and local ablation can improve the patient ´s survival. However, the disease is detected in advanced stage; moreover some available therapies are restricted to palliative care and local treatment. Early detections of HCC and adequate therapy are crucial to increase survival as well as to improve the patient´s quality of life. Therefore, researchers have been investigating molecular biomarkers with high sensibility and reliability as Golgi 73 protein (GP73), Glypican-3 (GPC3), Osteopontin (OPN), microRNAs and others...

Breast cancer is an important cancer among solid organ transplant recipients. While the incidence of breast cancer in solid organ transplant recipients is comparable to the age matched general population, the outcomes are generally poor. Interventions such as cancer screening which preclude the development of late stage disease through early detection are not well-studied, and clinical practice guidelines for cancer screening rely solely on recommendations from the general population. Among those with a prior breast cancer history, disease recurrence after transplantation is a rare but fearful event...

The newer and potent immunosuppressive agents have successfully reduced the risk of rejection after kidney transplantation, but the development of cardiovascular diseases, infections, and malignancy is major factors limiting their success. Posttransplantation malignancy is the second most common cause of death in renal transplant recipients after cardiovascular disease; it is expected that mortality due to malignancy may become the most common cause of death within the next two decades. This study is designed to evaluate the incidence, risk factors, and types of malignancies occurring after renal transplantation and their impact on patient and graft survival...

BACKGROUND: Scirrhous gastric cancer is an intractable disease with a high incidence of peritoneal dissemination and obstructive symptoms (e.g., ileus, jaundice, and hydronephrosis) arising from accompanying marked fibrosis. Microenvironmental interactions between cancer cells and cancer-associated fibroblasts are the suggested cause of the disease. We elucidated the mechanisms of tumor growth and fibrosis using human peritoneal mesothelial cells (HPMCs) and investigated the effects of tranilast treatment on cells and a xenograft mouse model of fibrosis...

Background. Yiqi Huayu Jiedu Decoction (YHJD) can obviously improve the quality of life of those patients with gastric cancer and prolong their survival. Methods. In vitro experiments, we observe YHJD's effect on the cells' proliferation by MTT assay. Cell adhesion assay, wound-healing assay, and Transwell invasion assay serve to detect its influence on cells' adhesion, migration, and invasion, respectively. Inhibitor (10 μM/L of SB431542) and activator (10 ng/mL of TGF-β) of TGF-β/Smad pathway were used to estimate whether YHJD's impact on the biological behavior of gastric cancer cells was related to TGF-β/Smad pathway...

Haematopoietic stem cell transplantation (HSCT) improves the survival rate of children and adolescents with malignant and non-malignant conditions; however, the physical, psychological and social burden of such a procedure is considerable both during and after treatment. The present qualitative study investigated the long-term effects of HSCT after pediatric cancer. Thirty adolescent and young adult (AYA) survivors (Mage = 23.61 years, SD = 5.21) participated in individual interviews and were invited to speak about their life experiences following their treatment and strategies they use to deal with their past medical experiences and the long-term sequelae...

The B-cell receptor (BCR) pathway plays an important role in the survival, proliferation and trafficking of cancer cells in a variety of B-cell malignancies. Recently, a number of agents have been developed to target various components of the BCR pathway. One such target is Bruton's tyrosine kinase (BTK), a Tec family kinase member found near the cell membrane that is involved in upstream BCR signaling. The biological function of BTK in several B-cell lymphoid malignancies has led to the development of the oral BTK inhibitor ibrutinib...

At steady state, hematopoietic stem cells(HSCs), the most undifferentiated cells in the hematological system, are kept quiescent in the cell cycle. Upon hematological stresses, including radiation, anti-cancer medication, infection, and transplantation, bone marrow HSCs enter the cell cycle and robustly repopulate the entire hematopoietic system via multi-lineage differentiation and self-renewal, partly due to the alteration of their surrounding microenvironment or niche. Such hematological repopulation activity is termed "stress hematopoiesis," an activity essential for homeostatic maintenance of blood production...

O-GlcNAcylation is a dynamic O-linked glycosylation event that plays a crucial role in regulating cellular signaling. Recent studies indicate that increased O-GlcNAcylation is a general feature in cancer and contributes to various cancer phenotypes, including cell proliferation, survival, invasion, metastasis, and energy metabolism. However, the role of O-GlcNAcylation in the tumor microenvironment (TME) is not fully elucidated. Here, B16 melanoma cells were subcutaneously transplanted into O-GlcNAc transferase transgenic (Ogt-Tg) mice exhibiting elevated O-GlcNAcylation to examine the effect of O-GlcNAcylation in the TME on tumor progression...

Chronic kidney disease (CKD) exacerbating vascular disease poses a major challenge to nephrology. Surgically placed vascular fistulas, as an aid to hemodialysis prior to kidney transplant, have extended many lives, while post-surgical restenosis closure of the fistula by smooth muscle cells affects many lives. When post-surgical restenosis is developed, palliative measures are almost always surgical: there are no effective drug treatments. In this study, we offer a testable hypothesis that effects of CKD on widely distributed vascular diseases and the phenomenon of fistula restenosis are both driven by the pathologic creation of non-dividing smooth muscle cells via asymmetric division of exponentially increasing metakaryotic stem cells...
