Natural killer cells harnessed from healthy individuals can be expanded ex vivo using various platforms to produce large doses for adoptive transfer into cancer patients. During such expansion, NK cells are increasingly activated and more efficient at killing cancer cells. Adoptive transfer however introduces these activated cells into a highly immunosuppressive tumor microenvironment mediated in part by excessive transforming growth factor beta (TGF-beta) from both cancer cells and their surrounding stroma...

Chemotherapy is one of the main approach for ovarian cancer. Cancer stem cells (CSCs) escape chemotherapy and lead to chemoresistance. We previously demonstrated that cordycepin (Cd) inhibited metastasis in human ovarian carcinoma cells, the aim of this study is to investigate the effects of Cd on ovarian cancer stemness. TGF-beta was used to induce chemoresistance of chemotherapeutic agent cisplatin in SKOV-3 ovarian cancer cells. After treating with 100 μM of Cd, cell viability, the percentage of cancer stem cells, and the levels of matrix metalloproteinases (MMPs) were decreased in TGF-beta-induced SKOV-3 cells...

BACKGROUND: Omalizumab is an anti-immunoglobulin E (IgE) monoclonal antibody used in the treatment of severe asthma. Its therapeutic efficacy is primarily attributed to reduction of serum-free IgE and in the expression of high-affinity IgE receptor, fc epsilon RI. However, its effect on the low-affinity IgE receptor fc epsilon RII/CD23 in vivo has not been evaluated. AIM: To determine whether CD23 plays a role in the inflammatory process in severe uncontrolled asthma and whether anti-IgE therapy modulates fc epsilon RII/CD23 expression in these patients...

A cohort of 19 patients affected by chronic venous ulcers was recruited from our centre. A 4-mm punch biopsy from wound bed was taken before application of ALA 20% gel and repeated one hour after the first PDT irradiation. We observed a significant and progressive reduction of wounds mean volumes right after three ALA-PDT sessions (once per week; 4479.9 +/- 345.5 mm3 vs 34599 +/- 190.3 mm3, p < 0.01). On immunofluorescence staining from biopsy specimens, we observed a change in all tested stains of post treatment specimens compared to pre-treatment ones...

Avian primordial germ cells (PGCs) have valuable potentials to cell-based approaches for transgenic bird production. In this regard, improvement of avian PGC expansion in vitro is necessary. Among experimental avian species, quail is a good model for transgenic technology, especially due to its short generation time. In the present study, we have examined the proliferative effects of transforming growth factor β (TGF-β) on the quail PGCs. After isolation of quail PGCs from blood [Hamburger-Hamilton (HH stages 13-15)] and gonads (HH stages 28-30), these cells were cultured on quail embryonic fibroblasts (QEF)...

Obesity is associated with an increased incidence of high-grade prostate cancer (PC) and poor prognosis for PC patients. Recently, we showed that obesity-related periprostatic white adipose tissue (WAT) inflammation, characterized by crown-like structures (CLS) consisting of dead or dying adipocytes surrounded by macrophages, was associated with high-grade PC. It's possible, therefore, that agents that suppress periprostatic WAT inflammation will alter the development or progression of PC. Pioglitazone, a ligand of PPARγ is used to treat diabetes and possesses anti-inflammatory properties...

T-cell acute lymphoblastic leukemia (T-ALL) is a disease of the blood affecting T-lymphocytes. Although notable improvements have been achieved in T-ALL treatment, half of the adult T-ALL patients still experience treatment failure. In order to develop a targeted therapy, we need a better understanding of T-ALL pathogenesis. In this study, we used patient-derived cell lines which display resistance to glucocorticoids. We observed that different cell lines are dependent on different survival signaling pathways...

Recent studies have shown that several long noncoding RNAs (lncRNAs) are involved in regulating the immune response to cope with pathogenic invasion. To date, the roles of lncRNAs in the CD4+ T cell response to Treponema pallidum (T. pallidum) infection in neurosyphilis patients remain unknown. The mRNA and lncRNA expression profiles of CD4+ T cells that were isolated from neurosyphilis patients and healthy controls were analyzed by microarray. A total of 2258 lncRNAs and 1728 mRNAs were identified as over-expressed or under-expressed, respectively (fold change > 1...

The molecular mechanisms underlying thoracic aortic aneurysm (TAA) in patients with bicuspid aortic valve (BAV) are incompletely characterized. MicroRNAs (miRNAs) may play a major role in the different pathogenesis of aortopathy. We sought to employ next-generation sequencing to analyze the entire miRNome in TAA tissue from patients with BAV and tricuspid aortic valve (TAV). In the discovery stage, small RNA sequencing was performed using the Illumina MiSeq platform in 13 TAA tissue samples (seven patients with BAV and six with TAV)...

Mediator is a conserved, multi-subunit macromolecular machine divided structurally into head, middle, and tail modules, along with a transiently associating kinase module. Mediator functions as an integrator of transcriptional regulatory activity by interacting with DNA-bound transcription factors and with RNA polymerase II (Pol II) to both activate and repress gene expression. Mediator has been shown to affect multiple steps in transcription, including chromatin looping between enhancers and promoters, pre-initiation complex formation, transcriptional elongation, and mRNA splicing...

Nodal is considered the key inducer of mesendoderm in vertebrate embryos and embryonic stem cells. Other TGF-beta-related signals, such as Vg1/Dvr1/Gdf3, have also been implicated in this process but their roles have been unclear or controversial. Here we report that zebrafish embryos without maternally provided vg1 fail to form endoderm and head and trunk mesoderm, and closely resemble nodal loss-of-function mutants. Although Nodal is processed and secreted without Vg1, it requires Vg1 for its endogenous activity...

To elucidate whether the endometriotic cells of endometriomas synthesize transforming growth factor beta1 (TGF-beta1) and understand how it affects surrounding ovarian tissue. We collected biopsies of the cystic walls from 42 endometriomas and 29 mature teratomas and compared mRNA and protein expression of fibrosis-related factors between the cystic walls. Then we detected TGFB1 mRNA synthesis in endometriomas, and tested TGF-beta1 fibrotic effect in vitro. Moreover, we verified the expression of Smad2/3 Signaling components in the endometriotic cystic wall in order to understand whether TGF-beta1/Smad signaling is involved in fibrosis formation of the tissue surrounding endometriomas...
