Phytopharmacological studies of different Calendula extracts have shown anti-inflamatory, anti-viral and anti-genotoxic properties of therapeutic interest. In this study, we evaluated the in vitro cytotoxic anti-tumor and immunomodulatory activities and in vivo anti-tumor effect of Laser Activated Calendula Extract (LACE), a novel extract of the plant(More)
OBJECTIVE To assess the contribution of 2 polymorphisms within the inducible nitric oxide (NOS2A) promoter region to the susceptibility to Henoch-Schönlein purpura (HSP), and to determine if implications exist with severe systemic complications of HSP, in particular with severe renal involvement and permanent renal dysfunction (renal sequelae). METHODS(More)
Nuclear factor (NF)-kappaB plays an important role in inflammatory diseases such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). A functional insertion/deletion polymorphism (-94ins/delATTG) has been identified in the promoter of the NFKB1 gene. In addition, a polymorphic dinucleotide repeat (CA) has been identified in proximity to the(More)
OBJECTIVE The aim of this study was to assess the possible association between the interleukin-12B (IL12B) and interleukin-12 receptor beta 1 (IL12RB1) gene polymorphisms with systemic lupus erythematosus (SLE). In addition, we have undertaken a systematic search for genetic variants of interleukin 23 (IL23A). METHODS The study was conducted on 559 SLE(More)
The aim of this study was to assess the possible association of the functional (GT)(n) microsatellite polymorphism in the FOXP3 gene with predisposition to several autoimmune diseases such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), ulcerative colitis (UC), Crohn's disease, and celiac disease. We analyzed a case-control cohort composed(More)
HLA class I loss or down-regulation is a widespread mechanism used by tumor cells to avoid tumor recognition by cytotoxic T lymphocytes, and thus favor tumor immune escape. Multiple mechanisms are responsible for these HLA class I alterations. In different epithelial tumors, loss of heterozygosity (LOH) at chromosome region 6p21.3, leading to HLA haplotype(More)
The aim of this study was to assess the possible association between the IL12B and the IL12RB1 gene polymorphisms and the systemic autoimmune disease rheumatoid arthritis (RA). Our study population consisted of 545 patients with RA and 393 healthy subjects. All the individuals were of white Spanish origin. Genotyping of the IL12B (IL12Bpro and IL12B 3'(More)
BACKGROUND This study investigated the influence of the NFKB1-94ins/delATTG in the susceptibility/phenotype to ulcerative colitis. METHODS We analyzed the distribution of -94ins/delATTG NFKB1 in 258 patients and 264 healthy controls from southern Spain by a polymerase chain reaction-fluorescent method. RESULTS The genotype and allele frequencies of(More)
CONCLUSION The results of this study support the assertion that Southern European individuals have a genetically mediated predisposition to develop idiopathic sudden sensorineural hearing loss (SNHL). OBJECTIVE To assess the influence of human leukocyte antigen (HLA)-DQB1 and -DRB1 alleles on the susceptibility to and the severity of idiopathic sudden(More)
Alterations in HLA class I antigen expression have been frequently described in different epithelial tumors and are thought to favor tumor immune escape from T lymphocyte recognition. Multiple molecular mechanisms are responsible for these altered HLA class I tumor phenotypes. Some are structural defects that produce unresponsiveness to treatment with(More)
