this study was performed to investigate two polymorphic sites from cyp19 gene (pvuii and mspi) and one polymorphic site from erα gene (snabi) in four cattle breeds including mazandarani, taleshi, sistani and simmental. in overall 278 samples for cyp19 and 206 samples for erα marker sites were genotyped using polymerase chain reactionsingle-strand conformation polymorphism (pcr-rflp) procedure. ...

suicide is a major public health concern, with approximately one million people committing suicide world-wide each year .risk factors for suicidal behavior include, psychiatric and medical illness, impulsivity, aggression, alcohol and drug abuse specially stimulants, and  stress. neurobiological, brain mappings and biochemical studies have revealed that suicide victims experiencing a large numb...

background: molecular diversity of leishmania major and its morphological changes have become a controversial issue among researchers. some aspects of polymorphic shapes of amastigotes in clinical manifestations along with molecular variation were evaluated among suspected patients of some exceptional zoonotic cutaneous leishmaniasis locations in northern khuzestan, southwestern iran. methods: ...

essential hypertension (eh) accounts for 90-95% of hypertension cases. eh, as a progressive cardiovascular syndrome arising from complex and interrelated etiologies, results from combined and interactive effects of genetic and environmental factors. the objective was to investigate the ace i/d and gnb3 c825t polymorphisms and both genotypes combined with seeking gene-gene interactions to furthe...

objective(s): foxp3 gene is an x-linked gene that encodes foxp3 protein, an essential transcription factor in cd4+cd25+foxp3+ regulatory t (treg) cells.  we aimed, in the present study, to investigate the association of two foxp3 polymorphisms, -2383 c/t (rs3761549) and ivs9+459 t/c (rs2280883), with lung cancer. materials and methods:  in a case-control study we analyzed genotypes and alleles ...

present investigation was carried out to identify dna polymorphism of il-2rγ and chb6 genes. sixty five birds belonging to the indigenous chicken of himachal pradesh were utilized. good quality dna samples were subjected to pcr-rflp analysis using chicken specific primers. overnight restriction enzyme digestion was carried out at 37°c with iu hph i and pvu ii for il-2rγ and chb6 genes, respecti...

canine distemper virus (cdv) creates a very contagious viral multi-systemic canine distemper (cd) disease that affects most species of carnivora order. the virus is genetically heterogeneous, particularly in section of the hemagglutinin (h) gene. sequence analysis of the h gene can be useful to investigate distinction of various lineages related to geographical distribution and cdv molecular ep...

In situ hybridization of mouse embryo sections demonstrated expression of mRNAs encoding two polypeptide inhibitors (p18INK4c and p19INK4d) of cyclin D-dependent kinase (CDK) 4 and CDK6 in the central nervous system. No expression of two other INK4 members, p16INK4a and p15INK4b, was observed. The p19INK4d and p18INK4c proteins formed complexes with either CDK4 or CDK6 in a temporal pattern con...

Leukotriene B4 (LTB4) is a potent pro-inflammatory eicosanoid that is derived from arachidonic acid, and its signaling is known to have a tumor-promoting role in several cancer types. In this study, we investigated whether enhanced LTB4 signaling confers resistance to the cytostatic transforming growth factor-β1 (TGF-β1) response. We found that LTB4 pretreatment or ectopic expression of BLT1, a...

Pancreatic cancer (PaCa) is the fourth leading cause of cancer deaths in Western societies, with pancreatic ductal adenocarcinomas (PDACs) accounting for >90% of such cases. PDAC is a heterogeneous disease that includes a subset showing overexpression of the secreted glycoprotein Dickkopf-related protein 3 (Dkk-3), a protein shown to be downregula...
