OBJECTIVES The tumor necrosis factor-alpha (TNF-α) gene may play an important role in coronary heart disease (CHD) and myocardial infarction (MI) risk. Recently, controversial results regarding the association of the G-308 A (rs1800629)polymorphism of the TNF-α gene with CHD/MI have been reported. We herein examine a possible association between the G-308 A (rs1800629)polymorphism of the TNF-α ...

BACKGROUND The tolerogenic peptide, hCDR1, ameliorated manifestations of systemic lupus erythematosus (SLE) via the immunomodulation of pro-inflammatory and immunosuppressive cytokines and the induction of regulatory T cells. Because type I interferon (IFN-α) has been implicated to play a role in SLE pathogenesis, we investigated the effects of hCDR1 on IFN-α in a murine model of SLE and in hum...

Abstract Wilt disease with unknown etiology causes mass mortality in commercial Acacia mangium nurseries South Sumatra. This pathogen induces symptoms of chlorosis the lower leaves and develops into shoots; subsequently, plants wither die. research identifies pathogenic species causing this wilt to assess its pathogenicity or virulence. Fifteen isolates Fusarium oxysporum varying colony sizes c...

ICP22 is a multifunctional herpes simplex virus 1 (HSV-1) immediate early protein that functions as a general repressor of a subset of cellular and viral promoters in transient expression systems. Although the exact mechanism of repression remains unclear, this protein induces a decrease in RNA polymerase II Serine 2 (RNAPII Ser-2) phosphorylation, which is critical for transcription elongation...

Maize transcription factors (TFs) opaque2 (O2) and the O2 heterodimerizing proteins (OHP1 and OHP2) originated from an ancient segmental duplication. The 22-kDa (z1C) and 19-kDa (z1A, z1B, and z1D) α-zeins are the most abundant storage proteins in maize endosperm. O2 is known to regulate α-zein gene expression, but its target motifs in the 19-kDa α-zein gene promoters have not been identified. ...

BACKGROUND We aimed to determine the incidence of co-inheritance as well as interaction of sickle cell trait (SCT) and α(thal)/β(thal) mutations in south and south central of Iran. METHOD We employed a PCR and restriction fragment length polymorphism techniques to confirm diagnosis of sickle cell trait. All subjects were screened for any α/β -thalassemia mutations using a gap-polymerase chain...

OBJECTIVE To investigate the relationship between gene mutations and protein expressions of PDGFR α and C-kit in gastrointestinal stromal tumors (GIST) and its significance in tumorigenesis. METHODS Single strand conformation polymorphism-polymerase chain reaction (PCR-SSCP), immunohistochemistry and Western blot were used to detect the gene mutations in PDGFR α and C-kit and their protein ex...

introduction: although the initial hypothesis for the action of doxepin was based on the inhibition of the reuptake of neurotransmitters, it has been suggested that it may also involve other mechanisms. therefore, this study aims to investigate the effect of doxepin on spatial memory, tumor necrosis factor alpha (tnf-α) level, expression of pro-apoptotic (bad and bax) and anti-apoptotic (bcl-2)...

conclusions our results show a significant association of nos3 and mthfr gene polymorphisms with coronary atherosclerotic lesions. therefore, these variants might influence the risk of coronary artery disease, specifically in the iranian population. results we specifically detected the nos3 tt genotype in 12 patients (11.11%) and did not find the same genotype in any of the controls. the freque...

The apparent stasis in the evolution of avian chromosomes suggests that birds may have experienced relatively low rates of gene gain and loss in multigene families. To investigate this possibility and to explore the phenotypic consequences of variation in gene copy number, we examined evolutionary changes in the families of genes that encode the α- and β-type subunits of hemoglobin (Hb), the te...
