Functional polymorphisms of the receptor for the advanced glycation end product promoter gene in inflammatory bowel disease: a case –control study
AbstractThe receptor for the advanced glycation end products (RAGE) is a multiligand transmembrane receptor involved in chronic inflammation whose specific polymorphisms of the promoter gene were found to increase its transcriptional activity. We investigated the association of both allelic and genotypic -374T/A and -429T/C polymorphisms with inflammatory bowel disease. The STREGA guidelines were applied for planning and reporting. We enrolled 133 patients with Crohn ’s disease (CD), 149 with ulcerative colitis (UC), and 128 blood donors. Genomic DNA was extracted from peripheral blood leukocytes collected from each ...

Neutrocyte-to-lymphocyte ratio predicts the presence of a replicative hepatitis C virus strand after therapy with direct-acting antivirals
AbstractResidual HCV-RNA can persist in liver tissue and peripheral blood mononuclear cells (PBMCs) long after antiviral therapy of chronic hepatitis C in patients repeatedly negative for viral RNA in serum. This occult infection associates with impaired immune response and the risk of lymphoproliferative disorders or progressive liver disease. There are currently no monitoring strategies for patients after treatment. We investigated if serum inflammation markers and interferon lambda (IFNL) genotype can be predictors of the presence of HCV-RNA and the replicative HCV-RNA ( −) strand in patients who reached sustained...

Circulating soluble levels of MIF in women with breast cancer in the molecular subtypes: relationship with Th17 cytokine profile
AbstractBreast cancer (BC) is a health problem worldwide; there is evidence that inflammatory cytokines are increased in BC. Macrophage migration inhibitory factor (MIF) has multiple effects on immune cells, inflammation and cancer. Besides, in previous studies, contradictory and uncertain results have been presented on the implication of Th17 cytokine profile in BC. The aim of this study was to evaluate the plasma levels of MIF and the Th17 cytokine profile in BC and their association with their molecular subtypes and clinical stage. A total of 150 women with BC of Ella Binational Breast Cancer Study and 60 healthy women ...

Adeno-associated virus as a gene therapy vector: strategies to neutralize the neutralizing antibodies
AbstractAdeno-associated virus (AAV)-derived vectors are currently the most common type of viral vectors used in gene therapy clinical trials. The presence of neutralizing antibodies (NAbs) against wild-type AAVs in the host body is one of the limitations for the successful use of AAV vectors. AAV capsid manipulation, by which recombinant vectors lose their ability to interact with NAbs, can help overcome this obstacle. Various methods can be used for this purpose, including directed evolution as well as conjugation of certain chemical groups to AAV epitopes. The present review concisely explains the use of AAV vectors in ...

AbstractThe colorectal cancer harbor germline, somatic or epimutations in mismatch repair genes,MUTYH orPOLE gene, which lead to the hypermutated and ultramutator phenotypes with increased immune response. The mutations inPOLE gene were reported to occur more frequently in early-onset colorectal cancer (EOCRC), and the patients are strong candidates for checkpoint inhibitor therapy. Here, we report mutation analysis within the endonuclease domain of thePOLE gene in the cohort of patients with EOCRC in order to identify recurrent or new mutations and evaluate their association with the presence of tumor-infiltrating lymphoc...

Expression of tetraspanins NET-6 and CD151 in breast cancer as a potential tumor biomarker
AbstractTetraspanins have been implicated in multiple biological functions including protein networking and cell signaling. NET-6 (TSPAN 13) has been demonstrated to be a tumor suppressor gene in breast cancer, while CD151 is more likely to act as an oncogene. However, the biological function of both proteins is still inconclusive. Immunohistochemistry was used to analyze the expression of NET-6 and CD151 proteins in breast tumors and benign epithelial cells. The cellular expression of both markers was correlated with HER2, ER, and PR status as well as tumor grade, Ki-67 scores, invasion, and metastasis. Expression of NET-...

Iloprost use and medical management of systemic sclerosis-related vasculopathy in Italian tertiary referral centers: results from the PROSIT study
AbstractVasculopathy is a crucial feature of systemic sclerosis (SSc), and Raynaud ’s phenomenon (RP) and digital ulcers (DU) have a deep impact on the quality of patients’ life. The management of vascular disease can be challenging for the clinician because of the suboptimal tolerability of the treatments and lack of consensus on the best therapeutic approach. Intravenous ilo prost, a synthetic analogue of prostacyclin, is broadly used for the treatment of RP and ischemic ulcers secondary to SSc. However, no standardized protocol on iloprost use is currently available and, consequently, the management of this ...

Comparison between clinical significance of serum CXCL-8 and classical tumor markers in oesophageal cancer (OC) patients
AbstractC-X-C motif chemokine 8 (CXCL-8), known as interleukin-8, is a pro-inflammatory cytokine which acts as a chemotactic factor, mainly for leukocytes. CXCL-8 is produced by malignant cells, and therefore it can stimulate the growth and progression of various neoplasms, including oesophageal cancer (OC). The aim of the current study was to measure serum concentrations of chemokine CXCL-8 in OC patients and establish whether this protein might be considered a potential candidate for a tumor marker in the diagnosis and progression of OC.

TRAF6 regulates YAP signaling by promoting the ubiquitination and degradation of MST1 in pancreatic cancer
AbstractTNF receptor-associated factor 6 (TRAF6), a regulator of NF- κB signaling, has been reported to be associated with the oncogenesis of various tumors including pancreatic cancer, but the underlying mechanisms remain unknown. Here, we found that knocking down the expression of TRAF6 impaired YAP signaling. Moreover, TRAF6 promoted the migration and colony form ation of pancreatic cancer cells through YAP. Then, we found that TRAF6 interacted with and promoted the ubiquitination and degradation of MST1, and the expression of TRAF6 and MST1 was negatively correlated in primary human pancreatic cancer samples.

Effect of antithyroid drugs on the occurrence of antibodies against type 2 deiodinase (DIO2), which are involved in hyperthyroid Graves ’ disease influencing the therapeutic efficacy
AbstractGraves ’ disease is an organ-specific autoimmune disease with hyperthyroidism, diffuse goiter and autoantibodies against TSH receptor, thyroid peroxidase (TPO) and/or thyroglobulin (Tg). Graves’ hyperthyroidism is characterized by T3 dominance due to the conversion of T4 into T3 through type 1 and 2 deiodinase enzymes (DIO1, DIO2). Methimazole (MMI) and propylthiouracil (PTU) therapies inhibit thyroid hormone synthesis blocking the activity of deiodinase and TPO enzymes. The study investigated the occurrence of autoantibodies against DIO2 peptides (cys- and hom-peptides) with the effect of antithyroid d...

AbstractThe complement system (CS) has recently been recognized as a bridge between innate and adaptive immunity that constitutes a very complex mechanism controlling the clearance of pathogens, cellular debris, and immune complexes. Out of three known pathways of complement activation, the alternative pathway (AP) plays a critical role in host defense by amplifying the complement response, independently of initiation pathway and continuously maintaining low-level activity in a process called ‘thick-over.’ A key molecule of the CS is C3, in which the AP is constantly activated. To prevent host cell destruction,...
